摘要： A tool has a pair of elongate housings adapted to be joined together in a housing assembly for enclosing and supporting a flexible drive mechanism entrained about a pair of rotatable elements. Each of the rotatable elements is disposed on the housing assembly at opposite ends thereof. A flexible drive mechanism provides a transfer of power between the rotatable elements so that rotation of one rotatable element at one input end of the housing assembly will effect driven rotation of the other rotatable element at an output end of the housing assembly. The elongate housings include male and female configurations for aligning and joining the housings without independent fasteners.

摘要： A power tong system is used to make up and break out threaded pipe connections. Rotary power tongs are connected to an integral backup tong through an extendable hydraulic cylinder and rod. A brake is secured to the rotary tong to selectively hold the pipe stationary relative to the rotary tong. When rotation of the pipe by the rotary tong ceases, the brake is applied, and the cylinder and rod are actuated to angularly displace the power tongs and the backup tong to apply a torque force to the pipe connection disposed between the power tongs and the backup. A resulting torque force is obtained that is greater than the maximum torque that can be exerted by the rotary tong 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 is regulated to limit its torque output. When the limited torque is reached, the brake is applied and the cylinder and rod 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 prevents the rotary tong from being turned backwardly by the increased torque force applied by actuation of the rod and cylinder assembly. Operation of the system may be manually or automatically controlled.

摘要翻译： 动力钳系统用于组装和拆卸螺纹管道连接。 旋转动力钳通过可伸缩的液压缸和杆连接到一体式后备钳。 制动器被固定到旋转钳，以选择性地将管道相对于旋转钳固定。 当通过旋转钳的旋转管停止时，施加制动器，并且致动缸和杆以使动力钳和支撑钳角度地移位，以向设置在动力钳和备用轮之间的管连接器施加扭矩力 。 得到的扭矩力大于单独作用的旋转钳可以施加的最大扭矩。 该系统还可以部署以在管道连接上施加并保持精确的扭矩力。 当用于获得低于最大额定旋转钳输出的补油扭矩时，旋转钳被调节以限制其扭矩输出。 当达到有限的扭矩时，施加制动器，并且致动缸和杆以对连接施加平滑，紧密控制的扭矩增加。 最终扭矩水平可以在所需的时间长度内保持恒定。 在高扭矩和低扭矩应用中，制动器通过由杆和气缸组件的致动而施加的增加的扭矩力来防止旋转钳向后转动。 系统的操作可以手动或自动控制。

摘要： The hand tool includes tree main parts, a support arm, a torque application arm and a socket. The socket is intended to grip into the bolt head and mediate a torque from the axle of the hand tool. The support arm forms a holding-up against a supporting base and the torque application arm is used to apply a torque. Both the support arm and the torque application arm have latching devices with respect to the axle, which locks in the same direction and implies that a torque applied by the torque application arm is maintained by action of the latching mechanism of the support arm. Furthermore, the hand tool is preferably designed with a torque enhancement.

摘要： An open throat power tong 10 for making up and/or breaking apart an oilfield tubular connection includes an open throat in the tong body 15. Motors 18, 20 rotate a partial ring member 12 and a pair of heads 16 with respect to the tong body. A door 40, 140 may be opened to expose the open throat of the power tong, and has a planar latch surface formed from arcuate groove 58 for receiving an arcuate boss 90. The door latch mechanism reduces the effort required to safely latch the door in the closed position before operating the tong, and provides a highly reliable mechanism to minimize spreading of the tong body under a relatively high torque.
