Steerable heavy duty axle unit

Abstract

A steerable heavy-duty vehicle bridge device comprises a main bearing beam and a vehicle bridge assembly, wherein a connecting base is arranged on the vehicle bridge assembly, and a rotating shaft is vertically and fixedly arranged on the connecting base; a vertical shaft hole is formed in the rear part of the main bearing beam; the rotating shaft is arranged in the shaft hole in a penetrating manner; the lower end of the main bearing beam is propped against and matched with the connecting base via a friction plate which is arranged on the rotating shaft in a sleeving manner; a steering driving mechanism is arranged on the main bearing beam; the power driving end of the steering driving mechanism is connected with the upper end of the rotating shaft. According to the steerable heavy-duty vehicle bridge device, the design is reasonable, the steering ability of the overall moving and transporting system of a drilling machine is greatly improved, the turning radius is reduced, the labor intensity is lowered, and the moving and transporting efficiency is improved; moreover, the structure is simple, the mounting operation is convenient, and the manufacturing cost is low. Furthermore, through the adoption of the device, the steering performance of the vehicle bridge is optimized, the moving and transporting performance of the overall drilling machine is qualitatively improved, and the problems that the turning is difficult and a well opening is difficult to align during well maintenance work are solved.

Description

technical field [0001] The invention relates to a transportation device for an oil drilling rig, in particular to a new type of special steerable heavy-duty axle device for drilling rigs with high transportation efficiency and low transportation cost. Background technique [0002] At present, the rear part of the overall transportation system of oil drilling rigs uses a non-steerable load-bearing bridge for transportation; the overall transportation of drilling rigs has a large turning radius, which is difficult to turn and labor-intensive. The device cannot be turned, and it is difficult to move, especially the rear axle of the overall movement system of the drilling rig cannot be turned and it is difficult to align the wellhead, requiring multiple adjustments, wasting manpower, material and financial resources. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a steerable heavy-duty axle device with sma...
