Pull-type drilling rig derrick base structure

The invention relates to the field of petroleum drilling and production equipment, in particular to an automated and modular pull-type drilling rig derrick base structure. The pull-type drilling rig derrick base structure comprises a base assembly connected with a foundation, a derrick assembly movably connected with the base assembly, and a trailer frame assembly movably connected with the base assembly and the derrick assembly, and further comprises connection fasteners movably connected with the base assembly, the derrick assembly and the trailer frame assembly correspondingly, jacking hydraulic cylinders fixedly connected with the trailer frame assembly or the base assembly, and supporting rods fixedly connected with the connection fasteners or the base assembly. The pull-type drillingrig derrick base structure has the beneficial effects that the turning radius is small, a using area is not limited, transferring can be conducted at a time, the mounting and carrying time is reduced, and automation and modu
