| A self-adjusting spinner is provided that is capable of accommodating various pipe sizes without requiring the need for an operator to climb up the support mechanism and manually change the position of the drive assembly. The self-adjusting spinner includes a case having two pivotally connected members: a stationary case member and a moving case member. Upper and lower plates having gear racks are mounted on the stationary case member for moving a drive assembly horizontally across the case. The drive assembly includes a motor that drives gear sprocket through a drive shaft. The drive sprocket then drives a chain that rotates a drill pipe in an operative position relative to the case. The spinner also includes an adjusting assembly mounted on the case that moves the drive assembly along the gear rack upon the actuation of an adjustment sequence. When the adjustment sequence is initiated, the effective length of the chain is adjusted to accommodate drill pipes of varying diameters. | ||||||

The system 10 and more particularly the mechanisms 12 and 14 engage and hold the rod R from a location radially adjacent a circumferential surface of the rod R inboard of its opposite ends, rather than from an end of the rod R. The surface engagement mechanism 12 is a distributed mechanism having two parts 12a and 12b that act at axially spaced locations on the rod R. The holding mechanism 14 is located and operates on the rod R between these axially spaced locations. The surface engagement mechanism 12 initially operates to engage the surface of the rod R which may for example be lying on a rod tray, to enable the rod to be lifted from a tray. Thereafter the holding mechanism 14 is operable to support and hold the rod. | ||||||

| In spinner tongs, a so-called spinner (30), incorporated in an iron roughneck and thus serving to rotate a drill pipe during connection thereof to a drill string or during division of the drill string into individual pipes, the aim has been to reduce damage on the threaded connections (the pin-and-box joints) in the screwing/unscrewing operations. This is realised in an operation for the simultaneous centering and rotating of the drill pipe. Four spinner rollers (42) known in themselves, which are brought to bear on the drill pipe when surrounding it, are mounted according to the invention, preferably in pairs, at the outer ends of driven clamping arms (46), by bogies (50). At their opposite outer ends the clamping arms (46) are pivotally supported on a fixed frame part/structure (56) and are jointed to each other by means of a piston and cylinder (48) driven by pressure fluid and arranged to carry the clamping arms (46) towards and away from each other. For their forced centering the clamping arms (46) have a centering stay (58) arranged thereto, which is connected by its outer end to one clamping arm (46), and is connected by its other outer end to the other clamping arm (46). For the parallel displacement of the rollers (42), each bogie (50) has a parallel stay (54) arranged thereto, whose other end is supported on a fixed frame part/structure (56). | ||||||

| The invention relates to an improved drill pipe spinner. The improved spinner may be used as a stand-alone piece of pipe handling equipment or may be used in an Iron Roughneck. The spinner comprises a pair of clamping arms that are movable between an open position and a closed position, wherein in the closed position, the arms will clamp about a pipe to be made up or broken out and in the open position, the spinner may be moved away from or towards the pipe. The arms are preferably moved between the open and closed positions by a hydraulically actuated clamping cylinder. Attached to the distal ends of each arm is a roller bracket. The roller brackets are preferably attached to the clamping arms by a roller bracket pin. Each roller bracket includes a pair of drive roller assemblies, which together form the spinning unit. Each drive roller assembly preferably comprises a pair of drive rollers, with each roller rotated by a pair of hydraulic motors. If the rollers of the spinner have to be repaired, serviced or replaced, the arm brackets are easily removed by simply pulling the roller bracket pin and removing the roller bracket. A new roller bracket may then be picked up, aligned with and pinned to the arm by reinserting the roller bracket pin. The spinning unit can easily be removed and replaced on the rig floor by changing out the roller bracket. | ||||||

| Drilling rig apparatus for connecting and disconnecting well pipe at a drilling rig. A remotely controlled power wrench assembly is mounted on a remotely controlled lifting mechanism attached to a base spaced about the well axis on the rig floor. The wrench assembly includes upper and lower wrenches carried by the lifting mechanism. The wrench assembly includes a lower wrench for gripping a lower box coupling of a drill pipe section at the well center. An upper wrench is provided for spinning an upper pin coupling into or out of threaded engagement with the lower box coupling. The upper wrench has two opposed spinner-roller pairs which translate between open and closed positions for spinning the upper pin coupling when in a closed position. The upper wrench also has two opposed jaw blocks which translate between open and closed positions for gripping the pin coupling in a closed position. The spinner roller pairs and the jaw blocks move in directions perpendicular to each other into and out of a cavity through which the well axis passes vertically. Torque cylinders are provided by which the upper wrench is torqued in a first or nulltorquing upnull direction while the jaw blocks are gripping the pin coupling and in a second or nullbreaking loosenull direction. A manipulator is pivotably carried on a rod supported from the wrench assembly. The manipulator includes a remotely controlled arm and hand assembly which captures a drill pipe section in its hand and transfers the drill pipe while being supported vertically by the drilling rig between the well axis and a position at the side-of the wrench assembly. The drilling rig apparatus includes a bore arranged and designed for placement on the rig floor around the well axis. A slot is provided between frame members for placement of a pneumatically remotely controlled power slip manipulator for setting and releasing slips in the rotary table for supporting the drill pipe string in the well bore during connecting and disconnecting operations of drill pipe sections. | ||||||
| 120 | Power wrench for drill pipe | US89750 | 1998-06-02 | US6065372A | 2000-05-23 | Vernon Rauch |
| A motorized wrench for spinning together (or apart) lengths of drill pipe as typically used in water well drilling. A single motor is connected by a pair of drive chains to two toothed drive rollers to spin the rollers and, thus, spin drill pipe engaged against them. The pipe is so engaged by means of a smooth idler roller within a pivot arm driven open or closed by an air ram. The invention is typically supported via light wire cable from a drill rig mast and when so supported is fast and easy to place, operate, and remove. The preferred configuration of the device operates on hydraulic power and compressed air, both of which are normally present on drill rigs. | ||||||
