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： Method and apparatus for handling a supported tubular string with a string elevator and a spider on a rig to prevent damaging contact between the string elevator and spider while facilitating further connections of add-on tubular segments. The string elevator and supported tubular string descend toward the spider until reaching a predetermined position. The process of setting the spider into engagement of the tubular string is automatically initiated in response to detecting the predetermined position of the string elevator. With the spider set, the string elevator can be unloaded. Optionally, the method may also automatically terminate the string elevator descent in response to detecting that the spider has been set. A preferred apparatus for detecting the position of the elevator includes a tilt switch secured to a fixed position along the length of the Kelly hose.

摘要： A spider for use within the rotary table opening has all movable elements flush with or below the rig floor. The conventional wedge shaped slips are supported and aligned by a slip carrier that has a spherical outer surface that slideably mates with a spherical bowl inner surface in the spider such that the pipe, slip, and slip carrier can tilt as a unit about any horizontal axis that passes through the spherical surface center.

摘要： The apparatus of the present invention is directed to a replacement cage assembly (106) to modify a conventional power tong (100) to enable the power tong to grip and rotate smaller diameter tubular segments (90). The method of the invention is directed to modifying a power tong (100) to grip and rotate a tubular segment of a diameter smaller than could be gripped by the unmodified power tong (100). The invention provides a rotary gear insert (240), having an interior second cam surface, rotatably captured intermediate an upper cage plate (230) and a lower cage plate (210) and slidably receivable within the conventional rotary gear of the power tong (100) and to cam and rotate a plurality of replacement gripping jaws (220, 221) pivotally captured adjacent the second cam surface (240) and intermediate the upper cage plate (230) and the lower cage plate (210).

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.
