Abstract

A method and apparatus for manipulating and deploying lengths of pipe when drilling wells is provided. The apparatus has a motor assembly with a rotor shaft coupled to a drive gear, and a torque assembly with a planetary gear set coupled to the drive gear of the motor and an annular gear. Planet gears are coupled to a torque converter, which is coupled to a stub for connecting to pipe joints. The torque converter has inclined surfaces for circulating lubricant through the gear assembly, and the planet gears have openings in registration with the inclined surfaces. A drilling fluid pipe is disposed through the rotor shaft of the motor assembly, and is coupled to the torque converter. Lead-screw linear actuators position an elevator, which hangs from links hooked to the apparatus, to manipulate the drill string, and a self-locking pipe jaw handles pipe joints.
