Abstract

See full text

A system for pushing and pulling rod strings through the ground or an underground pipe. The apparatus has a downhole tool attached to the distal end of the rod string. The push/pull machine has a stationary frame that is placed against the ground to provide a reaction surface. The stationary frame has an opening for the rod string to pass through. A rod gripping assembly is supported on the machine frame and moveable relative to the stationary frame. The push/pull machine has a powered rod section spinner to add or remove rod string sections from the rod string. An actuator powers movement of jaws into a spinner bowl to cause a powered gripping of the rod string section. With the rod string section gripped a motor is activated to rotate the rod string section to connect it to a rod string or disconnect it from the rod string.
