Abstract
A pipe handler that can include a wrench assembly with a backup tong and a torque wrench, and a rotary actuator coupled to the torque wrench, wherein rotation of the rotary actuator about a second axis rotates the torque wrench about a first axis. An iron roughneck that can include a torque wrench configured to rotate about a first axis, and a rotary actuator coupled to the torque wrench, the rotary actuator having a second axis about which the rotary actuator rotates, where the second axis and the first axis are substantially parallel with each other and spaced apart from each other, and where rotation of the rotary actuator about the second axis rotates the torque wrench about the first axis.
Claims20
A pipe handler for a subterranean operation, the pipe handler comprising:
- a wrench assembly comprising a backup tong and a torque wrench having a first axis;
- and
- a rotary actuator coupled to the torque wrench, wherein rotation of the rotary actuator about a second axis rotates the torque wrench about the first axis.
An iron roughneck for applying a torque to a tool joint in a subterranean operation, the iron roughneck comprising:
- a torque wrench configured to rotate about a first axis;
- and
- a rotary actuator coupled to the torque wrench, the rotary actuator configured to rotate about a second axis, wherein the first axis and the second axis are substantially parallel with each other and spaced apart from each other, and wherein rotation of the rotary actuator about the second axis rotates the torque wrench about the first axis.
A method for applying a torque to a tool joint in a subterranean operation, the method comprising:
- engaging a tool joint with a first plurality of grippers of a torque wrench;
- rotating a rotary actuator about a first axis;
- rotating the torque wrench about a second axis in response to rotation of the rotary actuator;
- and
- rotating at least a portion of the tool joint about the second axis in response to the rotation of the torque wrench.
