Apparatus for forcing threadless joints of pipe axially into a coupling to effect a string of pipe. The apparatus includes a main frame movable longitudinally along the projected path of a pipeline to be constructed. A pipe gripper is mounted to the main frame for slidable movement longitudinally along the pipeline. The pipe gripper comprises a plurality of pipe engaging dies remotely actuated to grip and release a marginal length of a pipe. A coupling holding fixture is affixed to the main frame in spaced relation respective to the pipe gripper. The fixture includes a movable wall which enables a coupling to be releasably held in fixed relationship respective to the main frame, and remotely released when desired. A coupling is placed within the fixture, a joint of pipe is placed within the pipe gripper which forces the pipe axially into the coupling whereupon the pipe connection is effected to thereby enable a pipeline to be fabricated. |
