A derrick moving device

Abstract

The invention relates to a derrick carrying unit and belongs to the technical field of carrying equipment for oil rig derricks. The derrick carrying unit comprises an axle assembly and a leg assembly. The frame assembly is fixedly connected to the axle assembly. A traction pin is disposed at the front end of the frame assembly. At least two bearing beams are detachably fixed on the frame assembly. Two ends of each bearing beam are provided with adjustable support fixtures capable of moving on the bearing beam. The leg assembly is disposed at the lower end of the frame assembly in the front-back direction of the axle assembly. When a derrick is carried, the bearing beams are arranged rotatably in the longitudinal direction and are connected to the frame assembly. The derrick carrying unit can be used to carry the whole derrick with no need for demounting the derrick module, is available for carrying derricks of all specifications and sizes, and is highly universal. In addition, the derrick carrying unit can be independently carried with a traction car with no need for hauling with large transporters or large cranes, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the transport equipment of the derrick of an oil drilling rig, in particular to a new special trailer device for the derrick of the drilling rig with high transport efficiency and low transport cost. Background technique [0002] At present, the overall transportation of the derrick of the oil drilling rig usually adopts the method of directly installing the ordinary trailer on the lower part of the derrick, and different types of derricks are transported by different types of trailers, and it is not convenient to place the parts. Parts, complex structure. With this structure, the transfer of the trailer itself is also inconvenient. It is necessary to use a large transport vehicle or a crane to transport the trailer to the hauling position. This moving device is time-consuming, laborious and economical. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide and design a d...
