Crawler-type pipeline aligning engineering truck

Abstract

The invention belongs to the technical field of pipeline transportation and particularly relates to a crawler-type pipeline aligning engineering vehicle. The crawler-type pipeline aligning engineeringvehicle is provided with a vehicle body, a trolley, a trolley frame, a pipe joint pushing device and a pipe joint rotating device, wherein the trolley is positioned on the trolley frames and is hinged relative to the trolley frames, the trolley horizontally ascends and descends relative to the trolley frames under the action of driving units II, the two trolley frames are arranged front and back,the trolley swings back and forth relative to a trolley body under the action of the driving units II corresponding to the two trolley frames, so the trolley, a pipe joint pushing device and a pipe joint rotating device which are positioned on the trolley are adjusted to swing back and forth, pitching angles of the pipe joint pushing device and the pipe joint rotating device on the trolley are adjusted, the two trolley frames are located on the trolley body and transversely move relative to the trolley body under the action of the driving units I, and therefore the trolleys hinged to the trolley frames are driven to transversely move or horizontally rotate. The crawler-type pipeline aligning engineering vehicle is advantaged in that aligning efficiency and safety are improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline transportation, and in particular relates to a crawler-type pipeline counterpart engineering vehicle. Background technique [0002] In the traditional laying of oil and gas pipelines, it is necessary to first arrange the pipes according to the construction route as a supporting mound, and then place the pipe joints in sequence. After the pipe joints are in place, the alignment and welding process begins. At present, the alignment process relies on two pipelayers to respectively lift the pipe joints to be welded and the pipeline ends. The matching process is complicated to operate, takes a long time, has low efficiency, and requires the intervention of large-scale lifting equipment, which has great potential safety hazards. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to propose a crawler-type pipeline counte...
