Abstract
A wrench assembly comprising an upper clamp assembly, a lower clamp assembly coupled to the upper clamp assembly, an alignment device disposed between the upper and lower clamp assemblies to allow the upper clamp assembly to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly, and an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly.
Claims20
A wrench assembly, comprising;
- a lower clamp assembly;
- an upper clamp assembly coupled to the lower clamp assembly that is adapted to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly;
- and
- an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly and configured to stop the lower or upper clamp assembly from applying torque to a tubular connection.

A wrench assembly, comprising;
- an upper clamp assembly;
- a lower clamp assembly coupled to the upper clamp assembly;
- an alignment device disposed between the upper and lower clamp assemblies, wherein the alignment device is configured to adjust an axis about which the wrench assembly applies torque by allowing the upper clamp assembly to move laterally relative to the lower clamp assembly;
- and
- an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly and configured to stop the lower or upper clamp assembly from applying torque to a tubular connection.

A wrench assembly, comprising;
- an upper clamp assembly;
- a lower clamp assembly coupled to the upper clamp assembly;
- an alignment device disposed between the upper and lower clamp assemblies, wherein the alignment device is configured to adjust an axis about which the wrench assembly applies torque by allowing the upper clamp assembly to move laterally relative to the lower clamp assembly, wherein the alignment device includes a wedge that engages a groove, the wedge being movable relative to a plate member of the lower clamp assembly;
- and
- an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly and configured to stop the lower or upper clamp assembly from applying torque to a tubular connection.
