MOBILE SERVICE RIG WITH INTEGRATE PIPE HANDLING ASSEMBLY

摘要

A mobile service rig with an integrated pipe handling assembly is provided. The rig includes an elongate frame, an attached elongate mast, and an attached a pipe handling assembly. The mast base is pivotally attached to the frame for moving the mast between horizontal and vertical orientations. The pipe handling assembly includes a pipe trough and a trough lifting arm pivotally attached to frame and pipe trough to move a pipe between a horizontal orientation and a vertical orientation collinear with the mast in the vertical orientation. The pipe handling assembly may also include a pair of pipe racks pivotally attached to the frame to extend transversely away from the frame.

1. A mobile service rig for handling a pipe, the rig comprising:
(a) an elongate frame defining a longitudinal axis and a transverse axis perpendicular to the longitudinal axis in a substantially horizontal plane; (b) a mast assembly comprising an elongate mast substantially aligned longitudinally with the frame and extending from a mast base to a mast crown, wherein the mast base is pivotally attached to the frame and moveable between a substantially horizontal orientation and a substantially vertical orientation; and (c) a pipe handling assembly attached to the frame and comprising:
(i) an elongate pipe trough substantially aligned longitudinally with the frame and moveable between a substantially horizontal position level with the frame and a pipe delivery position substantially parallel with the mast; and(ii) at least one trough lifting arm having a first end pivotally connected to the frame directly or indirectly, and a second end pivotally attached to the pipe trough for moving the pipe trough between the horizontal position and the pipe delivery position.
