Multipurpose cantilever skidding frame

摘要

The present subject matter provides a multipurpose cantilever skidding frame having a first frame structure, a second frame structure and two connection beams integrally forming a rigid structure to provide longitudinal and lateral movement for an exemplary cantilever. The present subject matter also provides a drilling rig that enables a cantilever to be moved in both longitudinal and transverse directions.

1. A cantilever skidding frame for a mobile platform, the frame comprising:
a first frame structure comprising a first aft corner structure, a first forward corner structure, and a longitudinal skidding foundation structure coupling the first aft and first forward corner structures; a second frame structure comprising a second aft corner structure, a second forward corner structure, and a longitudinal skidding foundation structure coupling the second aft and second forward corner structures; two beams connecting the first and second frame structures to form a rigid skidding frame; transverse skidding driving mechanisms fixedly connected to each aft and forward corner structures of the first and second frame structures; and longitudinal skidding driving mechanisms fixedly connected to one of the forward or aft corners of each first and second frame structures, wherein the rigid skidding frame is disposed on parallel transverse skidding tracks, wherein longitudinal movement of a cantilever disposed on the rigid skidding frame is effected by operation of the longitudinal skidding driving mechanisms, and wherein transverse movement of the cantilever disposed on the rigid skidding frame over the parallel transverse skidding tracks is effected by operation of the transverse skidding mechanisms and wherein the rigid skidding frame is fixed in the longitudinal direction.
