81 Drill tool EP81850019.1 1981-02-06 EP0036847A2 1981-09-30 Wiredal, Harry Artur Ingvar

A drill tool for rotary and/or percussion drilling with drill rod means (14) within casing tube means (15) comprises a centric cutting bit (11) and an eccentric reamer cutter (12), both provided with hard metal inserts. For purposes of obtaining a life of the drill tool as long as possible the first frontal insert (23) on the reamer cutter (12) is positioned in front of the first peripheral insert (18) when seen in the rotational direction (D) during drilling, and the centric cutting bit (11) provided with more inserts on the half (38) of its front surface opposed to the reamer cutter (12) during drilling than on the other half (39).

Die Erfindung betrifft eine sich öffnende Dreh-Schlagbohrkrone, die nach durchlaufen einer Außenverrohrung bei Grundkontakt zwangsläufig aufklappt und größer bohrt als der Durchmesser der Außenverrohrung misst, wobei die beweglichen Teile der Dreh-Schlagbohrkrone quer zum Kronenschaft drehbar gelagert sind und einen Bohrkopf bilden und die zum Bohren benötigte Energie durch Hydraulikhämmer oder Imlochhämmer zugeführt bekommt und zum Gestängewechsel oder nach vollendeter Arbeit ohne Verdrehen entgegen der Arbeitsdrehrichtung einfach in das Außenrohr zurückgezogen werden kann.

Ferner betrifft die Erfindung eine Bohrkrone (10), insbesondere zum Überlagerungsbohren, mit einem Bohrkopf (30) und einem den Bohrkopf (30) tragenden Bohrkronenträger (20), mit zumindest einem Klappflügel (32, 34), der zwischen einer ersten Position und einer zweiten Position hin und her bewegbar ist, wobei der zumindest eine Klappflügel (32, 34) in der ersten Position innerhalb eines Bohrkronendurchmessers (d10) angeordnet ist und in der zweiten Position über den Bohrkronendurchmesser (d10) hinausragt, und wobei der Klappflügel (32, 34) an seinem freien Ende eine Stirnfläche (40) aufweist. Der wenigstens eine Klappflügel (32, 34) ist quer zu einer Bohrkronenträgerlängsachse (70) schwenkbar am Bohrkronenträger (20) angeordnet und konstruktiv so ausgebildet, dass bei rotierendem Bohrkopf (30) eine Wirkverbindung mit einem Bohrobjekt ein Drehmoment an dem Klappflügel (32, 34) quer zur Bohrkronenträgerlängsachse (70) erzeugt und den Klappflügel (32, 34) von der ersten in die zweite Position treibt.

The invention relates to a drilling tool and a method for down-the-hole drilling, the drilling tool being intended to drill a hole ahead of a following casing tube (13). The drilling tool comprises a central pilot drill bit (20), a reamer (33) and a guide body (12) for steering the drilling tool and casing tube relative to one another. To avoid problems with threaded connections, the guide body (12), reamer (33) and pilot drill bit (20) are mutually formed so that the rotational power is transferred from the guide body (12) to the reamer (33) and from the reamer (33) to the pilot drill bit (20), but without either of the two transfers of rotational power comprising any threaded connection, and so that an essentially radial displacement exists between the guide body (12) and the reamer (33). The construction also facilitates retraction of the reamer (33) without the pilot drill bit also needing to rotate.

A tool (20) is described for transporting cutting segments (22) to and from a ground drill (12) to enable in situ replacement of the cutting segments (22). The ground drill is provided with seating means (30) for seating the cutting segments (22). The tool has a carrier cradle (176) onto which the segments can be loaded for transport to and from the ground drill (12) and is operable to cause the segments to slide relative to the tool when the tool passes a predetermined position within the ground drill, so that one end (70) of the segments can extend laterally of the tool an the segments engage the seating means (30) for retention in the cutting position.

An insert (24) is described for releasably retaining cutting means (22) in a ground drill (12). The insert is in the form of a substantially cylindrical member and is movable within the ground drill between an installation position and a retrieval position. In the installation position the insert (24) retains the cutting means in a cutting position between an outer circumferential surface (212) of the insert and an inner circumferential surface (26) of the ground drill. In the retrieval position the insert (24) is retracted to release the cutting means from between the outer circumferential surface of the insert and the inner circumferential surface of the ground drill.

97 Flushing means for drilling tools EP90850128.1 1990-04-03 EP0391874A3 1991-04-03 Löf, Stig Uno

A flushing means for drilling tools comprises a guide member (10) carrying a drill bit (20) and being rotatably centered by the mouth of a casing tube (11) which is adapted to follow the drilling tool downhole during drilling. The drill bit (20) has a bit portion (22) that projects laterally beyond and is spaced axially in front of the casing tube (11) so as to drill a hole larger than the casing tube (11). There are external flushing grooves (70,71) on the guide member (10) adapted to lead the outflow of flushing medium and debris from the hole during drilling into the casing tube (11). At least one of these grooves (70) extends from front to rear of the guide member (10). One or more further grooves (71) are open towards said rear while ending blindly into the peri­phery of the guide member (10) spaced from its front. By re­traction of the guide member (10) its front enters the casing tube (11). That closes the blind grooves (71) and an intensi­fied flushing is thus possible via the remaining open grooves (70) that extends from front to rear of the guide member (10). The cutting front (40) of the bit portion (22) is flushed rotatively in counter flow to the rotational drilling direc­tion (8) towards the full length groove (70).

A drilling tool is followed by a casing tube (11) down the drilled hole. The mouth of the casing tube (11) centers rotatably a guide member (10) which receives rotation and impact energy via the interior of the casing tube (11). A drill bit (20) consists integrally of an axially protruding pilot portion (23), a sidewise projecting eccentric portion (22) and a rear shaft (21). The shaft (21) extends pivotally and axially movably into an eccentrically disposed bore (24) in the guide member (10). Axially spaced peripheral end grooves (30,32) extend in opposite direction from an axial cam groove (31) on the shaft (21) and are engaged by a follo­wer (28) in the guide member (10) defining positively the axial and angular movability and positions thereof relative to the drill bit (20). In the forward end groove (32) the follower (28) maintains the drill bit (20) axially in dril­ling position adjacent to the guide member (10) with the eccentric portion (22) protruding to drill a hole larger than the casing tube (11). In an intermediate position 90° away from the drilling position, the follower (28) enters the cam groove (31) whereby the guide member (10) becomes axially movable the distance between the end grooves (30,32). In a rear axial position the guide member (10) by a continued 90° turn brings the follower (28) into the rear end groove (30) to axially define the retracted position of the drill bit (20), wherein it can be raised or lowered freely through the casing tube (11).
