摘要： A power tong system (10) is used to make up and break out threaded pipe connections. Rotary power tongs (15) are connected to an integral backup tong (25) through an extendable hydraulic cylinder and rod (30, 31). A brake (19) is secured to the rotary tong (15) to selectively hold the pipe stationary relative to the rotary tong. When rotation of the pipe by the rotary tong (15) ceases, the brake (19) is applied, and the cylinder and rod (30, 31) are actuated to angularly displace to power tong (15) and the backup tong (25) to apply a torque force to the pipe connection disposed between the power tong (15) and the backup tong (25). A resulting torque force is obtained that is greater than the maximum torque that can be exerted by the rotary tong (15) acting alone. The system may also be deployed to apply and hold precise torque forces on the pipe connections. When used to obtain a makeup torque below the maximum rated rotary tong output, the rotary tong (15) is regulated to limit its torque output. When the limited torque is reached, the brake (19) is applied and the cylinder and rod (30, 31) are actuated to apply a smooth, closely controlled increase in torque to the connection. The final torque level may be held constant for a desired length of time. In both the high and low torque applications, the brake (19) prevents the rotary tong (15) from being turned backwardly by the increased torque force applied by actuation of the rod and cylinder assembly (30, 31). Operation of the system may be manually or automatically controlled.

摘要： A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment.

摘要： A wrench for making up or breaking up a pipe joint is provided. The wrench comprises a tong assembly having an upper tong and a lower tong. The upper tong has a first upper tong half pivotably connected to a second upper tong half at their first ends. The lower tong has a first lower tong half pivotably connected to a second lower tong half at their first ends. A central bearing operatively couples the upper tong and the lower tong to allow the upper tong to rotate relative to the lower tong or vice versa. The tong assembly has a ram assembly for pushing or pulling the upper tong at a tangential location thereof and the ram assembly is retracted or extended to move the tong assembly between an open position, a closed position, and a rotated closed position where the upper tong is rotated relative to the lower tong.

摘要： A power tong having a door that pivots in a vertical plane that is parallel to a plane that includes the axis of the tubular being made up or broken down by the power tong. The door is pivotally coupled to a power tong body for movement between an open position, that allows a tubular joint to be introduced through a throat and into a bay of the power tong, and a closed position that closes the bay of the power tong to enable the gripping and rotating components of the power tong to be engaged to grip and rotate the tubular joint introduced into the power tong. The power tong door includes structures that are engaged upon pivotal closure of the door with corresponding structures on the power tong body.

摘要： A test stand, for testing several parameters of power tongs used to make and break drill and casing pipe segments, comprises a base having a vertical, rotating shaft bearing along its length one or more disk brakes for stopping rotation of the shaft induced by tongs. In a particular embodiment, a vertical mast on the base supports a rotatable gantry which can lift and move power tongs into place above the test stand. Sensors detect several parameters which determine tong performance. Measurements of torque, RPM, temperature, pressure and speed are contrasted to standards for power tongs of like size and capacity and feedback as to the tongs' ability to make and break drill and pipe joints is provided. In another embodiment, a derrick sits atop the base and supports a second, inverted test stand for testing integrated power tongs.
