DETAILED DESCRIPTION OF THE DRAWINGS

The following embodiments are merely illustrative and are not intended to be limiting. It will be appreciated that various modifications and/or alterations to the embodiments described herein may be made without departing from the invention and any modifications and/or alterations are within the scope of the contemplated invention.

The terms “coupled” and “connected”, along with their derivatives, may be used herein. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may be used to indicated that two or more elements are in either direct or indirect (with other intervening elements between them) physical or electrical contact with each other, or that the two or more elements co-operate or interact with each other (e.g. as in a cause and effect relationship).

With reference to FIGS. 1a and 1b, a drilling tower with a rod handling tower and a rod rack system 10 is shown. The drilling tower 10 has a central structure 20 with a main tower 30 and a rod handling tower 40. A rod rack system 50 is comprised of a first and second rod rack 52 and 54 which are not interconnected. The central structure 20 is not connected to the rod rack system 50. The drilling tower 10 shown in FIGS. 1a and 1b is a drilling tower which is incorporated within a mobile drilling platform with a number of other elements.

With reference to FIG. 2 and according to one embodiment of the present invention, the drilling tower 10 is shown without the rod rack system. The drilling tower 10 has a central structure 20 and a main tower 30. The drilling tower 10 also has a rod handling tower 40 which allows the retrieval and storing of rods used in the drilling process through the use of a rod rack system further described below. The rod handling tower 40 is shown in a lowered position which allows a rod to be retrieved from a rod rack system (not shown) or alternative to store a rod within a rod rack system. The rod handling tower 40 has a rod 60 positioned within the rod handling tower. The rod handling tower 40 will displace rod 60 from the rod handling tower 40 to the main tower. The central structure 20, main tower 30 and rod handling tower 40 are constructed from steel trusses as would be known by a worker skilled in the relevant art. The steel trusses can be modified to various sizes based on the required application.

With reference to FIG. 3, securing means on the rod handling tower 40 allow to secure rod 60 to the rod handling tower 40. An example of securing means on the rod handling tower 40 are comprised of hydraulic or pneumatic opposing clamps 70 which partially surround rod 50. As opposing clamps 70 are moved closer to one another, rod 50 is secured to the rod handling tower 40. Other types of securing means could be used to secure a rod to the rod handling tower as would be known by a worker skilled in the relevant art. The securing means can also be displaced away from the rod handling tower 40 through the use of a displacement piston 80 which can be hydraulic or pneumatic. A displacement piston 80 can be positioned on each securing means on the rod handling tower 40 or a single displacement piston can be positioned on a securing means. If a single displacement piston is utilized, the other securing means require an extendable section to be displaced with the other securing means having a displacement piston. Once the rod is within the securing means, the rod is positioned within a chuck as further described below. The Displacement of the chuck within the drilling tower would be based on chuck displacement means as known by a worker skilled in the relevant art.

With further reference to FIG. 3, the rod handling tower 40 also has receiving plates 90 which enable the placement of a rod 60 onto the rod handling tower prior to the securing means securing a rod onto the rod handling tower 40. When a rod is positioned onto the receiving plates 90 the securing means such as opposing clamps 70 are retraced underneath the receiving plates in order to allow a rod to rest on the receiving plates 90. Once the rod is positioned onto the receiving plates 90, the opposing clamps may be extended through the displacement piston 80 toward rod 60 in order to secure the rod onto the rod handling tower 40 and raising the rod away from the receiving plates. Alternatively, the displacement piston only travels a distance which positions the opposing clamps 70 at the same height as the receiving plates 90. The displacement piston 80 is also required to transfer the rod 60 from the handling tower 40 onto the main tower of the central structure.

With reference to FIG. 4 and according to one embodiment of the present invention, the rod handling tower 40 is shown with the securing means comprised of opposing clamps 62 and a support tip 100 located at one extremity of the rod handling tower. The support tip 100 allows for greater control of rod 60 when displacing the rod 60 to the main tower (not shown). The support tip 100 could also have securing means as described under FIG. 3.

With reference to FIG. 5 and according to one embodiment of the present invention, the rod handling tower 40 has displacement means which allow for the displacement of the rod handling tower 40 to the main tower (not shown). The displacement means shown in FIG. 4 consist of hydraulic or pneumatic cylinders 110 and 120 connected to the rod handling tower 40 and the central structure 20. The cylinders 110 and 120 are shown in a fully extended position which allows for the lowering of the rod handling tower 40. Support cylinders 130 and 140 are also connected to the rod handling tower and the central structure which provides added support for the rod handling tower 40. A pivot point 150 secures the rod handling tower 40 to the central structure 20 and also allows for the rod handling tower to travel from a lowered position as shown in FIG. 4 to a parallel position to the main tower 30 which is further described below. Other displacement means could be utilized allowing for the displacement of the rod handling tower such as electrical or mechanical as would be known by a worker skilled in the relevant art.

With reference to FIG. 6 and according to one embodiment of the present invention, the rod handling tower 40 is displaced from a lowered position to an inclined position through cylinders 110 and 120 being retracted which lifts the rod handling tower 40. The clamps 70 secure rod 60 onto rod handling tower to assure that rod 50 does not move during the displacement of rod handling tower 40 in closer proximity to the main tower 30.

With reference to FIG. 7, the rod handling tower 40 is adjacent to the main tower 30 which allows for a rod to be transferred from the rod handling tower 40 to the main tower 30. The cylinders 110 and 120 are fully retracted displacing the rod handling tower 40 as shown in FIG. 7. The main tower 30 has positioning cylinders 32 and 34 allowing for the main tower 30 to be in an operating position as shown or in a non-operating position by lowering the main tower 30 in close proximity to the central structure 20. The rod handling tower 40 can be displaced from pivot point 150 within an angle rotation range of −5 degrees to 120 degrees. With further reference to FIG. 7 and according to one embodiment of the present invention, the main tower 30 has a receiving platform 180 in order to transfer rod 60 from rod handling tower 40 to the main tower 30 and will be further described below.

With reference to FIG. 8 and according to one embodiment of the present invention, the receiving platform 180 on main tower 30 is shown in greater detail. The receiving platform 180 has an opening 182 with transfer means in close proximity to the opening 182. The transfer means consists of opposing rollers 190 which can be displaced along the surface of receiving platform 180 allowing for opening 182 to be narrower or larger. The displacement of the opposing rollers 190 is achieved through the use of hydraulic or pneumatic pistons 192 and 194. Through the extension of pistons 192 and 194, the opposing rollers 190 are displaced closer to one another. If the pistons 192 and 194 are retracted, the opposing rollers 190 will be displaced further apart from one another and providing a wider opening to opening 182.

With further reference to FIG. 8 and according to one embodiment of the present invention, rod 60 is displaced into opening 182 through the movement of opposing clamps 62 on the rod handling tower. Once rod 60 is positioned between opposing rollers 190, the opposing rollers 190 are moved toward rod 60 narrowing opening 182 and securing rod 60 between opposing rollers 190. With rod 60 secured within opposing rollers 190, opposing clamps 62 are released from rod 60 allowing for the rod handling tower 40 to be moved away from the main tower 30.

With reference to FIG. 9 and according to one embodiment of the present invention, the central structure 20 and main tower 30 are shown without the rod handling tower. The main tower 30 has a chuck 1010 with a gear box 1150 positioned within the main tower 30. The chuck 1010 and gear box 1150 travel in parallel relationship to the main tower 30 through extension pistons 250 and 252. During a drilling operation, the chuck 1010 and gear box 1150 remain at the lower section of the main tower 30 or at the extended position of pistons 250 and 252. The chuck 1010 and gear box 1150 travel upwards when rods (not shown) are being extracted after a drilling operation. The operation of the chuck and gear box are further described below.

With reference to FIGS. 8 and 9, once a rod (not shown) is secured within opposing rollers 190 and the rod handling tower (not shown) is lowered, the chuck 1010 and gear box 1150 can travel upward to retrieve a rod (not shown) within opposing rollers 190. The securing of a rod onto another rod being held by chuck 1010 is achieved by the mobility of displacement piston 80. Specifically, displacement piston 80 can displace opposing clamps 62 parallel to receiving platform 180 as well as parallel to the main tower 30. The movement of opposing clamps 62 parallel to the main tower 30 once the rod handling tower is parallel to the main tower 30, allows for a rod to be lowered into another rod being held in position by chuck 1010. By lowering a rod into a rod held by chuck 1010, opposing clamps 62 are released and opposing rollers are activated to engage both rods via threads present in rod being held by chuck 1010. In order to secure a rod onto chuck 1010, the chuck 1010 needs to be positioned in a manner that a rod can clear over the chuck and be held in position by the opposing rollers 190.

With reference to FIGS. 10 and 11 and according to one embodiment of the present invention, the rod rack system 50 is shown without the central structure and the rod handling tower. The rod rack system 50 has a first rod rack 52 and a second rod rack 54 which is longer in length. Rod rack 52 is not connected to rod rack 54 and a predetermined distance is measure between the racks. The desired distance between both racks 52 and 54 is the distance allowing for a rod handling tower (not shown) to be lowered in between both racks and allowing for a transfer of a rod onto a rod handling tower.

With further reference to FIG. 11 and according to one embodiment of the present invention, racks 52 and 54 have retrieving levers 300 which remove rods from the rod handling tower (not shown). Once the rod handling tower is positioned in between racks 52 and 54, levers 300 are rotated towards the opposing racks positioning tips 310 of the levers under a rod positioned on a rod handling tower (not shown). Once positioning tips are underneath a rod, levers 300 are rotated toward their respective racks lifting the rod from the rod handling tower and positioning the rod on the top surface of racks 52 or 54. The levers 300 are able to rotate a full 360 degrees in either clock or counter clockwise motion. In another embodiment levers 300 only rotate in a range of 180 degrees.

With reference to FIG. 12 and according to one embodiment of the present invention, once a rod (not shown) is positioned a top surface 600 of rack 52, a rod will travel along an inclined surface towards stoppers 400 positioned at the opposite end from levers 300 on rack 52. The stoppers 400 have a control wheel 410 positioned in close proximity to the stopper 400 allowing rods to travel to a second surface 610 on rack 52 once the control wheel 410 is activated. The rods are positioned on second surface 610 of rack 52 by allowing a rod positioned on the first surface 600 to drop into spacers 420 in control wheels 410. With the rotation of control wheel 410, a rod will travel from the first surface 600 of rack 52 to second surface 610 which is underneath first surface 600 of rack 52. Once the rod is on second surface 610 of rack 52, a rod can be displaced along the inclined surface of the second surface 610 based on a predetermined angled which will direct the rod to a second control wheel 500 positioned underneath levers 300. The second control wheel 500 allows for the positioning of rods onto a rod handling tower (not shown).

With reference to FIG. 13 and according to one embodiment of the present invention, the second control wheels 500 have contact surfaces 510 which allows a rod to be positioned onto it and with the rotation of the second control wheels 500, the rod is lifted from the rack and dropped onto a rod handling tower (not shown). The levers 300 on opposing racks will be off-set to assure that if the levers deployed simultaneously that the levers 300 will not contact each other. The racks of the rod rack system of the present invention can have one or more levers, stoppers, first and second control wheels with one or more contact surfaces. The rotational movement of the stoppers, first and second control wheels is a full 360 degrees.

With reference to FIG. 14 and according to a first embodiment of the present invention, a chuck system 1010 is shown generally comprised and encased by a housing 1015, secured to a cover 1020 by means of first bolts 1025. In turn, the cover 1020 is fastened to a cap 1030 by means of second bolts 1026, and said cap 1030 is fastened to a bushing 1035 by means of third bolts 1027. A drill rod (not shown) is secured to the chuck system 1010 by positioning said drill rod (not shown) into the main aperture 1040, said main aperture 1040 being circumferentially defined by the area within the bushing 1035, through the chuck system 1010 and out of a gear box (not shown) which is in threaded engagement with the housing 1015. Said gear box (not shown) also engages with an adapter 1045 of the chuck system 1010. The functioning of the chuck system 1010 and positioning and handling of the drill rod (not shown) is further explained below.

The operation of the drilling tower with a rod handling tower and rod rack system as described above is fully automated and does not require the use of any manual operators. The automation of the operation of these components would be based on the knowledge of a worker skilled in the relevant art.

With reference to FIGS. 15, 16 and 17 and according to a first embodiment of the present invention, the chuck system 1010 is generally comprised of a housing 1015 which is in threaded engagement with a gear box (not shown). A cylindrical bowl 1050 is operatively connected to the housing 1015 by means of a plurality of radially spaced springs 1055, serving to bias the bowl 1050 in an upward position, in the direction of the cap 1030 and bushing 1035. The springs 1055 bias an outer edge portion 1057 of the bowl 1050, forcing said bowl 1050 upwards. Therefore, in the position at rest of the springs 1055, an upper surface 1060 of the bowl 1050 is flush with an inner surface 1062 of the cover 1020. In other words, when no drill rod (not shown) is present in the chuck system 1010 and the system 1010 is at rest, the upper surface 1060 of the bowl 1050 will be flush with the inner surface 1062 of the cover 1020. The presence of the drill rod (not shown) will not allow the contact of the upper surface 1060 to the inner surface 1062 as the inherent size and shape of said drill rod (not shown) will force jaws 1070 outward towards the bowl 1050, said bowl 1050 thence forced downwards. This functioning is further described below.

With specific reference to FIG. 17, the radially spaced apart springs 1055 are shown in greater detail, exerting pressure and biasing the bowl 1050 in an upward position. FIG. 3a specifically shows the chuck system 1010 in a first position, whereby the jaws 1070 are not yet pushed inward and ready to grab onto the drill rod (not shown).

With further reference to FIGS. 15 and 18, a plurality of radially-spaced jaws 1070 are operatively engaged with the bowl 1050, said jaws 1070 able to grasp onto the drill rod (not shown). Said jaws 1070 are further comprised of friction inserts 1072 which serve to facilitate the grasping of the drill rod (not shown), and a plurality of hooks 1075 which engage corresponding cylindrical protrusions 1080 located on the bowl 1050. The jaws 1070 are held in place and biased outwards by means of a split ring (not shown) which is in an annular form and located within each jaws 1070. The split ring (not shown) can converge on itself such that inward movement of the jaws 1070 with respect to one another is permitted; however, the jaws 1070 are constantly biased in an outward position with respect to the center of the chuck system 1010. In a first position of the chuck system 1010, the hooks 1075 of the jaws 1070 are flush against and within the protrusions 1080 of the bowl 1050. As such, the jaws 1070 allow for the drill rod (not shown) to be freely inserted within and out of the chuck system 1010. In a second position of the chuck system 1010, the springs 1055 force the bowl 1050 upwards, thus the protrusions 1080 of said bowl 1050 move upwards as well and force the hooks 1075 and therefore the jaws 1070 in an inward position relative to the center of the chuck system 1010. Forcing said jaws 1070 inwardly allows the inserts 1072 to grasp onto the drill rod (not shown) and secure it within the chuck system 1010.

With reference to FIGS. 15 and 19 and according to a first embodiment of the present invention, the cylindrical bowl 1050 is shown connected to an actuator sleeve 1090 by means of connecting rods 1095. Therefore, the movement imparted upon the actuator sleeve 1090 is similarly reflected onto said bowl 1050. The connecting rods 1095 are not connected to the housing 1015, as spacers 1092 exist between said connecting rods 1095 and the housing 1015 to separate their respective movement. The actuator sleeve 1090 has an annular groove 1100 in a lower portion thereof and a retaining clip 1105 (also known in the art as a circlip) is located therein. The retaining clip 1105 is connected to a lower ring 1110 which is in turn connected to a bearing 1115. As such, the load of the bearing 1115 is transferred onto the lower ring 1110, the retaining clip 1105 and ultimately onto the actuator sleeve 1090 and the bowl 1050. A piston 1120 is also shown, operatively connected to the actuator sleeve 1090 by means of the bearing 1115, lower ring 1110 and retaining clip 1105 as was explained. A chamber 1125 is also present, which allows for a liquid such as oil to flow within said chamber 1125 to engage the piston 1120. In a first position as was explained above, liquid has been inserted within the chamber 1125 and thus forcing the piston 1125 in a downward position. Correspondingly, the piston engages the bearing 1115, lower ring 1110 and retaining clip 1105 downward, said retaining clip 1105 within an annular groove 1100 of the actuator sleeve 1090. The actuator sleeve 1090 is also forced downwards, which, due to the connecting rods 1095 connecting said actuator sleeve 1090 to the bowl 1050, also forces said bowl 1050 downward. In this first position, the jaws 1070 do not engage the drill rod (not shown). In a second position, the fluid is removed from the chamber 1125, and the biasing force of the springs 1055 forces the bowl 1050, and thus correspondingly the actuator sleeve 1090, retaining clip 1105, lower ring 1110, bearing 1115 and piston 1120, upwards. As was previously explained, this biasing force of the springs 1055 forces the jaws 1070 inwards with respect to the center of the chuck system 1010.

With reference to FIG. 20 and according to one embodiment of the present invention, the chuck system 1010 is connected to a gear box 1150. Said gear box 1150 is connected to the chuck system 1010 by means of a threaded engagement between threads on the housing 1015 and threads on a spindle 1155 of the gear box 1150. By rotating said spindle 1155 of the gear box 1150, the housing 1015 is rotated as well. Rotating motion is mimicked on all connected parts as enumerated above, including the bowl 1050, jaws 1070, springs 1055, actuator sleeve 1090, retaining clip 1105, lower ring 1110, bearing 1115 and not including the piston 1120 and a base 1166. Indeed, the movement of the piston 1120 and base 1166 are independent from the remainder of the parts on the chuck system 1010 and will not rotate with the spindle 1155 of the gear box 1150. The adapter 1045 of the chuck system 1010 is also designed to engage an upper portion 1160 of the gear box 1150, and said adapter 1045 serves to hold the base 1166 of the chuck system 1010 onto the gear box 1150, and while preventing the adapter 1045 and base 1166 from spinning with the housing 1015.

Caps (not shown) may also be required in order to cap the ends of the core samples once said core samples have been inserted into the first and second sets of circular apertures 1225, 1227. The caps (not shown) are fitted into the second apertures 1227 of the container 1220. The cold box 1215 is further comprised of its own lid 1240 to enclose and contain the core samples as described earlier.

With reference to FIG. 23 and according to a first embodiment, of the present invention, the cold box assembly 1210 is shown assembled with the cold box 1215 inserted within the insulating container 1220. An exemplary cap 1245 is shown which is inserted into the second sets of circular apertures 1227 to completely insulate the core samples within the cold box 1215. In this particular embodiment, a stand 1250 is shown which serves to secure the cold box assembly 1210 in a position above-ground.

With reference to FIG. 24 and according to a first embodiment, of the present invention, the cold box assembly 1210 is shown assembled with the insulated lid 1235 in a closed position. Front flap 1230 is in an open position in order to illustrate the second set of circular apertures 1227 and the cap 1245 which is to be inserted within said apertures 1227. Handles 1255 are located on the outer side of the insulated lid 1235 in order to facilitate the handling of the cold box assembly 1210.

With reference to FIGS. 25 and 26 and according to another embodiment of the present invention, a drilling tower 10 is shown with a structural frame 20, main tower 30 and a rod handling tower 40. The drilling tower is shown with a rod rack system comprised of a first rod rack 5200, a second rod rack 5400 and a rod support 5500. The rod handling tower 40 is positioned in between first rod rack 5200 and second rod rack 5400. As in other embodiment, rod racks 5200 and 5400 are not connected or attached to one another. The rod handling tower also is not connected or attached to either rod racks 5200 and 5400.

With reference to FIG. 27 and according to another embodiment of the present invention, a rod rack system is shown without the presence of the drilling tower and rod handling tower. The rod support 5500 is also not attached to either rod racks 5200 and 5400. The rod support 5500 is to allow the rod rack system to manipulate longer rods as would be positioned within the rod rack 5400.

With reference to FIG. 28 and according to another embodiment of the present invention, rod rack 5200 is shown in greater detail. Rod rack 5200 is comprised of a structural frame having opposing steel trusses 6200 and 6400 and ground frame 6500. A worker skilled in the relevant art would be familiar with a number of ground frames that could be utilised for a rod rack of the present invention. Rod rack 5200 also has two control wheels 6600 and 6700 which allow for the transfer of a rod from the rod rack 5200 to a rod handling tower (not shown). The control wheels 6600 and 6700 can only transfer a single rod from rod rack 5400 to a rod handling tower (not shown). The control wheels 6600 and 6700 have rod receiving indentations 6800 and 6900 allowing for the placement of a rod (not shown) within such indentations. The various steps to transfer a rod from a rod rack to a rod handling tower will be described further below. The control wheels 6600 and 6700 rotate around an axis on the structural frame of the rod rack. The rotation of control wheels 6600 and 6700 is in synchronised with both indentations 6800 and 6900 being aligned with one another. The power source for the rotation of the control wheels 6600 and 6700 can be any number of sources such as electrical, hydraulics or any other power source as would be known by a worker skilled in the relevant art. Shaft 6950 also links both control wheels 6600 and 6700 allowing for synchronisation of both control wheels and also only requiring a single power source to either control wheel in order to activate them.

With further reference to FIG. 28 and according to another embodiment of the present invention, rod rack 5200 has retrieval arms 7000 and 7100 positioned near control wheels 6600 and 6700. The retrieval arms 7000 and 7100 allow for the removal of a rod from a rod handling tower and to transfer them to the rod rack 5200. Rod rack 5200 also has two rod displacement controls 7200 and 7300. Rod displacement controls 7200 and 7400 control the travel of a rod (not shown) on steel trusses 6200 and 6400. In the present embodiment rod displacement controls consist of two hydraulic arms allowing to raise or lower the steel trusses 6200 and 6400. With the raising of the hydraulic arms 7200 and 7300, a rod will travel towards wheel controls 6600 and 6700 whereas with the lowering of hydraulic arms 7200 and 7400 a rod will travel at the opposite end of the steel trusses 6200 and 6400 which is away from control wheels 6600 and 6700.

With further reference to FIG. 28 and according to another embodiment of the present invention, rod rack 5200 also has stops 8000 and 8100 at one end of steel trusses 6200 and 6400 which assure that a rod does not fall off the rod rack 5200. Support trusses 8200 and 8300 are hinged on steel trusses 6200 and 6400 and link together steel trusses 6200 and 6400.

With reference to FIG. 29 and according to another embodiment of the present invention, control wheel 6600 is shown in greater detail. The movement of control wheel 6600 is powered by a hydraulic arm 7600 wherein with the extension of hydraulic arm 7600, control wheel 6600 will rotate away from the rod rack positioning the rod receiving indentation in a position to receive a rod (not shown). A worker skilled in the relevant art would be familiar with a number of power sources allowing for the rotation of the control wheel 6600. A shaft also links both control wheels.

With reference to FIG. 30 and according to another embodiment of the present invention, rod support 5500 is shown in greater detail. Rod support 5500 is composed of a steel frame with a steel trust 8800 wherein an end of a rod can rest upon. A control wheel 5600 is also positioned on rod support 5500 allowing for the transfer of rods from a rod rack to a rod handling tower. The control wheel 5600 is also only used to load a rod onto a rod handling tower. As indicated above, the use of any control wheels must be synchronised otherwise a rod cannot be transferred from the rod handling tower to a rod rack or vice versa. Rod support 5500 also has a power source to rotate control wheel 8800 in the form of a hydraulic arm.

The elements described for rod rack 5400 are also present in rod rack 5200 such that any opposing rod rack system would have identical elements.

The transfer of a rod from a rod rack to a rod handling will be shown through FIGS. 31 to 34 and the removal of a rod from a rod handling tower and transferred to a rod rack will be shown through FIGS. 35 to 37.

With reference to FIG. 31 and according to one embodiment of the present invention, a rod 9000 is positioned on rod rack 5200. Control wheels 6600 and 6700 are rotated in order to place rod receiving indentations 6800 and 6900 onto rod 9000. The rod displacement controls (not shown) would be positioned in a manner that would move all rods including rod 9000 toward the control wheels 6600 and 6700. Through the use of rod receiving indentations 6800 and 6900 on control wheels 6600 and 6700 assures that only one rod is selected to be moved from the rod rack 5200 onto rod handling tower 40. The rod receiving indentations 6800 and 6900 are limited in shape such that only a single rod can be positioned within the indentations.

With reference to FIG. 32 and according to another embodiment of the present invention, the control wheels 6600 and 6700 are rotated away from rod rack 5200 and towards rod handling tower 40. The rotation of control wheels 6600 and 6700 is powered by a hydraulic arm (not shown). The deployment of the hydraulic arm on control wheel 6600 and 6700 rotates the control wheels 6600 and 6700 away from rod rack 5200 and toward rod handling tower 40. With further reference to FIG. 32, rod 9000 is clearly positioned within the rod receiving indentations of control wheels 6600 and 6700 allowing for the transfer of rod 9000 to rod handling tower 40.

With reference to FIG. 33 and according to one embodiment of the present invention, rod 9000 is positioned onto rod handling tower once the control wheels 6600 and 6700 have rotated to the point that the rod receiving indentations 6800 and 6900 can no longer support rod 9000. Control wheels 6600 and 6700 do not contact rod handling tower 40. Once the rod receiving indentations are positioned as shown in FIG. 33, the mere weight of rod 9000 will transfer rod 9000 onto the rod handling tower 40 by falling on the rod handling tower 40. Rod 9000 will fall onto rod receiving plates 9100 and 9200 as positioned on rod handling tower 40.

With reference to FIG. 34 and according to one embodiment of the present invention, control wheels 6600 and 6700 will rotate towards rod rack 5200. By rotating away from rod handling tower 40, this will allow rod handling tower 40 to be raised toward the main tower (not shown) on the drilling tower (not shown). Rod 9000 will be secured to rod handling tower 40 through securing means defined as opposing clamps 70. The transfer of another rod from a rod rack to a rod handling tower can then be repeated as described under FIGS. 31-34.

With reference to FIG. 35 and according to one embodiment of the present invention, a rod 9000 is removed from rod handling tower 40. In order to remove rod 9000 from rod handing tower 40, opposing clamps 70 are raised which in turn raises rod 9000 away from rod handling tower 40. Once rod 9000 is raised, retrieval arms 7000 and 7000 are extended underneath rod 9000. Retrieval arms 7000 and 7100 are extended through the use of hydraulic arms (not shown) allowing the retrieval arms to be positioned underneath rod 9000. Once retrieval arms 7000 and 7100 are positioned underneath rod 9000, opposing clamps 70 are released and lowered which in turn transfers rod 9000 onto retrieving arms 7000 and 7100. A worker skilled in the relevant art would be familiar with various power sources allowing for the retrieving arms to be extended and retracted.

With reference to FIGS. 36 and 37 and according to one embodiment of the present invention, once rod 9000 is positioned on retrieving arms 7000 and 7100, rod 9000 will travel directly to control wheels 6600 and 6700 since retrieving arms 7000 and 7100 are angled upwards assuring the travel of rod 9000 toward control wheels 6600 and 6700. When receiving a rod at this stage, control wheels 6600 and 6700 are rotated to assure that rod receiving indentations are positioned to receive a rod as shown in FIG. 36. With reference to FIG. 37, once rod 9000 is within the rod receiving indentations on control wheels 6600 and 6700, control wheels 6600 and 6700 are rotated toward rod rack 5200 which in turn will transfer rod 9000 onto steel trusses 6200 and 6400 to roll toward the stops on the rod rack system.

A worker skilled in the relevant art would appreciate that only one rod rack could be used with a rod handling tower and a drilling tower. It is not necessary to have two rod rack system as shown.

A worker skilled in the relevant art would also understand that the control wheels as defined above could be defined as scoop wheels. A worker skilled in the relevant art would also understand the retrieving arms described above as covering indexing arms allowing for the removal of arms from the rod handling tower.

With reference to FIGS. 38 and 39 and according to another embodiment of the present invention, a chuck system 2010 is shown, generally comprised of a housing 2015 to engage the chuck system 2010 to a gear box (not shown). A cylindrical bowl 2050 is also shown, operatively connected to the housing 2015 by a plurality of radially spaced apart biasing means 2055 which in this embodiment are shown as springs. At least two cartridges 2022 are present, each cartridge 2022 further comprised of at least one sloping inner surface (not shown) to actuate at least two corresponding jaws 2070, whereby each cartridge 2022 is attached to the cylindrical bowl 2050. A worker skilled in the art would appreciate that more than two jaws 2070 and corresponding cartridges 2022 can be utilized, and that in this particular embodiment six jaws 2070 and cartridges 2022 are present to manipulate a drill rod (not shown). The jaws 2070 are operatively connected to said cartridges 2022 by means of a plurality of securing members 2024, and serve to grip onto or release a drill rod (not shown). Said jaws 2070 are further comprised of a longitudinally extending friction inserts 2072 along the length of the jaws 2070 in order to provide griping means to clasp onto the drill rod (not shown). An actuator sleeve 2090 is provided, fastened to the cylindrical bowl 2050 by means of radially spaced apart connecting rods 2095. The actuator sleeve 2090 is operatively coupled to a piston 2120 by means of a cylindrically-shaped bearing 2115. While the bearing 2115 provides for circular movement to the actuator sleeve 2090, and correspondingly to the bowl 2050, cartridges 2022, jaws 2070 and housing 2015, the position of the piston 2120 remains the same relative to said circular motion. An annular chamber 2125 is provided in order to receive a fluid therein, and thus actuates the piston 2120 in a downwards movement. Therefore, downward movement from the piston 2120 engenders corresponding vertical downward movement from the bearing 2115, actuator sleeve 2090, bowl 2050 and cartridges 2022, which will in turn push the jaws 2070 inwards horizontally. In turn, the jaws 2070 will manipulate the drill rod (not shown), which is to say that the jaws 2070 can clamp on or release the drill rod (not shown) depending on the movement of the adjacent cartridges 2022. This functioning is further explains below; however, a worker skilled in the art would appreciate that there are two positions for the chuck system: a first, clamping position whereby the biasing means 2055 are in a first position forcing the bowl 2050 upwards and thus the jaws 2070 inwards to clamp onto the drill rod (not shown), and a second, releasing position whereby a fluid is introduced into the annular chamber 2125 and forces a piston 2120 downwards, and correspondingly the bowl 2050 and biasing means 2055 downwards and thus the jaws 2070 inwards to release the drill rod (not shown). A worker skilled in the art would appreciate that the connection between the chuck system 2010 to a gear box (not shown) is similar to that which was described above.

With reference to FIGS. 40, 41 and 42, the securing members 2024 are further described, comprised of a shoulder bolt 2031, a friction pad 2032 and a coil 2033. As is shown, the shoulder bolt 2031 is secured within the jaw 2070 such that the horizontal motion of the jaw 2070 is reflected onto the shoulder bolt 2031 and the securing members 2024 overall. Indeed, a sliding aperture 2034 is present, allowing for the horizontal movement of the securing members 2024 separate from the upwards and downwards vertical movement of the cartridge 2022 and bowl 2050 as described above. Said vertical movement of the cartridge 2022 relative to the horizontal movement of the jaw 2070 is allowed by means of sloping inner surface 2036 on the cartridge 2022. As the cartridge 2022 moves upwards, the sloping inner surface 2036 pushes against a corresponding sloping outer surface 2037 of the jaw 2070 as is specifically shown in Figure E and represented by movement arrows. At any given moment in the motion of the chuck, the jaw 2070 is biased outwards, against the cartridge 2022 by means of the securing members 2024. This biasing is specifically shown in Figure C and is achieved by providing a friction pad 2032 biased flushly against the sliding aperture 2034 of the cartridge by means of coil 2033. Since the shoulder bolt 2031 is secured within the jaw 2070 and not secured to the cartridge 2022, the jaw 2070 is always forced outwardly and towards the cartridge 2022.

With reference to FIG. 43, the actuator sleeve 2090 is shown connected to both a plurality of connecting rods 2095 and operatively coupled to a piston 2120 by means of a cylindrically-shaped bearing 2115. The bearing 2115 is held in place and supported by means of a lower ring 2110 and a retaining clip 2105, and said bearing 2115 allows for the rotational movement of the actuator sleeve 2090 relative to the piston 2120 which does not rotate and is held in place by means of a lock pin 2038 thus only moves in a vertical motion. Indeed, an annular chamber 2125 is present which allows for the injection of fluid in order to move the piston 2120 in a downwards motion. Downward movement of the piston 2120 pushes the actuator sleeve 2090 downward which cause the remainder of the chuck system to move downward, with the except of the aforementioned jaws (not shown) which move inward to clasp onto the drill rod (not shown). When fluid is removed from the annular chamber 2125, upwards pressure from the biasing means (not shown) overcomes the downwards pressure exhibited from the fluid and thus forces the bowl (not shown), actuator sleeve 2090, bearing 2115 and piston 2120 upwards to a position at rest. As was previously described, when a spindle (not shown) is introduced from the gear box (not shown) into the chuck system 2010, it will rotate and thus rotate the parts enumerated above; namely, the bowl 2050, jaws 2070, biasing means 2055, actuator sleeve 2090, retaining clip 2105, lower ring 2110, bearing 2115 and not including the piston 2120.

With reference to FIG. 44, the chuck system 2010 is shown with handles 2039 connected to a cover 2020 for easy manipulation of the chuck system, while a nozzle 2041 is also provided as a lubrication point for gear box (not shown).

Logging

Normally, at the end of the coring, when the limestone is reached, a logging tool is lowered to analyze the ground in situ. This logging tool is comprised of an array of various sensors relayed to a data acquisition device on the surface. Typically the area of interest for study is situated just above or within the limestone layer. It is thus necessary to drill into or below the limestone to give the logging tool access to the area of interest. The logging is in sections and once assembled can be up to 25 M long. Hence, the hole must be drilled deeper than the point of interest to provide access for the logging tools. To avoid premature wear of the interchangeable coring assembly tools, the limestone is drilled with a standard bit.

    • Trip out all drill rods to remove core assembly.
    • Load rods (1) with standard bit.
    • Load rod (2).
