摘要： An apparatus for making up or breaking out of two members having mating threaded connections, such as pipe joints or bolts for avoiding undesirable transverse forces relative to the two members during tightening (or loosening), thereby insuring the connection is made up (or broken out) by essentially pure torque loads.The apparatus includes a power-driven lead tong, a back-up tong, a load cell which cooperates with either tong to produce a torque measurement and an interconnecting frame and isolation apparatus which eliminates transverse forces relative to the two threaded members. The power-driven lead tong rotatingly drives the first threaded member about its axis either clockwise or counterclockwise, as required. The back-up tong secures the second threaded member against axial rotation in response to the rotation of the first member. The interconnecting frame and isolation apparatus adapts the lead tong to the back-up tong in such a manner that their relative tendencies to rotate about the threaded members, in opposite directions, counteract each other. Also, by means of interconnecting members and isolation apparatus allowing relative movement along x, y and z axis between the lead tong and the back-up tong, but which does not allow relative rotation about the z axis, the interconnecting frame prevents undesirable transverse forces from occurring, between the lead tong and the back-up tong in response to the driving torque of the lead tong. Further, by means of said interconnecting members and isolation apparatus, the interconnecting means eliminates transverse forces which would otherwise develop because of irregularities of the threaded members (such as bent members or eccentric lead). A load cell cooperating with the isolation apparatus, internally disposed in the interconnecting frame, cooperates between the isolation apparatus and the tong housing to produce a torque measurement without inducing transverse forces on the threaded members.

摘要： An apparatus for making up and breaking out of pipe, bolts or other threaded members, and for measuring the amount of torque being applied to the threaded connection, without causing the application of undesirable transverse forces during the tightening or loosening process.The apparatus includes a conventional power-driven lead tong, a back-up tong with a pivotal mounted inner frame which cooperates with a load cell, and an isolated torsional transfer structure which interconnects the lead tong and back-up tong through pairs of three mutually peripendicular linear slides. The load cell, pivotally mounted inner frame and external housing of the back-up tong cooperate to produce a torque measurement without creating any unpaired linear forces against the connection being made. The three mutually perpendicular slides of the interconnecting frame allow for the transferal of torque between the lead tong and back-up tong, so that their relative tendencies to rotate about the work piece in opposite direction is resisted, but the slides eliminate any net linear forces between tongs. By eliminating all unpaired linear forces arising out of the torque measuring process, and by eliminating all unpaired linear forces arising out of each tong resisting the other tong's tendency to rotate, threaded connections are tightened and loosened by pure torque alone, with no transverse or bending forces applied to the connection.

摘要： A spider, preferably a flush mounted spider, and powered lead tong are coupled by a rotationally rigid structure so that torque reaction forces apply no side load to pipe. The tong preferably tilts upward to clear larger objects approaching the spider. An optional grabber is mounted, preferably atop the lead tong, and may tilt with the lead tong. Fluid powered motors, linear or rotary, provide the tilting energy and extend and retract the grabber. The tong and related structure has quick coupler provisions for removal from the spider.

摘要： An apparatus for gripping tubular members about their outer diameter without causing surface damage or structural deformation to the tubular members, so that they may be axially rotated or secured against axial rotation. A generally cylindrical internal sleeve is contained within a molded flexible liner. One side of the internal sleeve is releasably attached to the flexible liner, forming an annular bladder-like structure within the flexible liner. Introduction of pressure into the bladder-like structure causes the flexible liner to inflate radially inward and thereby grip tubular workpieces within the friction grip. Axial splines on the releasable side of internal sleeve interfit mate with corresponding splines of the molded flexible liner, thereby evenly distribute torque forces throughout the flexible liner rather than such torque forces being concentrated at only the edges of the flexible liner. Movable anti-extrusion rings at the axial edges of the flexible linear prevent deformation of the liner into the annular space between the outer sleeve of the friction grip, and also prevent wear between the axial edges of the liner and the edges of the outer sleeve. An additional, non-rigid sleeve, or coating, of friction enhancing material may be placed on the inner face of the flexible liner to increase the frictional characteristics of the grip and/or increase service life of the surface of the flexible liner. Instead of being made of one annular section, the friction grip may be made of two, or more, hingedly connected sections so as to allow the gripper to be attached at the midpoint of tubular workpieces without having to slide it over one end of workpiece.
