Abstract

A torque slider tong assembly provides a safe, convenient, light weight, portable, hand-operable dual pipe wrench for use in makeup and breakout of tubular connections. The torque-slider tong assembly includes a backup arm forming a first pipe wrench gripping a first pipe, a torque arm forming a second pipe wrench gripping a second pipe, and an actuator providing motive force moving the torque arm relative to the backup arm transverse to the pipes, which rotates the pipes relative to each other. A torque slider adjustably connects the actuator to the backup arm to adjust the mechanical advantage between the backup arm and the torque arm providing additional setup flexibility. Similarly, a movable pivot point, such as a clevis, adjustably connects the actuator to the torque arm providing additional setup flexibility. Quick-change pins allow positional adjustment of multiple components.

Dependent claims

A tong assembly for rotating a first pipe with respect to a second pipe about an alignment axis, comprising:

a backup arm comprising a backup arm jaws for selectively gripping the first pipe;
the back up arm having a plurality of torque slider position holes arrayed along a length of the backup arm;
a torque arm comprising a torque arm jaws for selectively gripping the second pipe;
the torque arm having a plurality of actuator position holes arrayed along a length of the torque arm;
the torque arm jaws being a modular backer jaws slidably received in a socket in the torque arm;
an actuator pivotably connected to the torque arm at a first end of the actuator and pivotably linked to the backup arm at a second end of the actuator for causing relative movement of the torque arm with respect to the backup arm transverse to the alignment axis, thereby causing relative rotation of the second pipe with respect to the first pipe about the alignment axis;
the actuator is a hydraulic actuator;
a torque slider movably captured on the backup arm at one or more of said plurality of torque slider position holes for selectively adjusting a connection point between the second end of the actuator and the backup arm for adjusting the relative movement of the torque arm with respect to the backup arm transverse to the alignment axis caused by extension and retraction of the actuator;
a pivot point movably and removably connected to the torque arm for selectively adjusting a connection point between the first end of the actuator and the torque arm at one of said plurality of actuator position holes for adjusting the relative movement of the torque arm with respect to the backup arm transverse to the alignment axis caused by extension and retraction of the actuator;
a torque angle gauge disposed at a pivot point between the torque arm and the actuator whereby said torque angle gauge indicates a relative angle between the torque arm and the back up arm;
and
a telescoping cross-arm stabilizer extends between the torque arm and the backup arm and is removably pivotably linked to the torque arm and is removably and slidably fixably linked to the back up arm.
