Abstract:
An apparatus for transferring torque comprising a pipe handling assembly configured to use fluid pressure to provide torque forces to set or release slips from a pipe. Set down force or other frictional measures on a pipe collar are not required. A method to create reactive torque force comprising a series of gears interconnected with each other through a clutch that can be engaged and disengaged. A link may be provided to a top drive rail via a gripperbox which provides reactive force to stop rotation of a power screw female (threaded nut) to facilitate threading action to set or release slips on pipe. Reactive force may be created using a plurality of axial pistons attached to a moveable half of a hirth coupling. Other friction-creating members (such as, for example, a brake pad material or similar material) may be used to create frictional forces between two surfaces.
