Auxiliary equipment for oil and gas long-distance pipeline construction and construction method thereof

Abstract

The invention discloses auxiliary equipment for oil and gas long-distance pipeline construction and a construction method thereof, and belongs to the technical field of oil and gas long-distance pipeline construction.The auxiliary equipment comprises a main frame and a welding part, the main frame comprises a base and two portal frames, and a rail assembly is connected between the tops of the two portal frames; the welding part is movably mounted on the rail assembly; a pipeline feeding part and a translation assembly are arranged on the side, away from the positioning part, of the base. The pipeline feeding part comprises a lifting assembly, a rotating assembly is arranged on the lifting assembly, and a pipeline conveying assembly is arranged on the rotating assembly; a clamping assembly is arranged at the top of the pipeline conveying assembly; position adjustment of the to-be-welded pipeline in three directions can be achieved, the position of the to-be-welded pipeline is adjusted through a mechanical structure, the welding part can achieve automatic welding of the pipeline, and safety and reliability are higher.

Description

technical field [0001] The invention relates to the technical field of construction of long-distance oil and gas pipelines, in particular to a construction method of auxiliary equipment for the construction of long-distance oil and gas pipelines. Background technique [0002] In the construction of long-distance oil and gas pipelines, welding is one of the main construction procedures. At present, the basic process mainly used in the welding of long-distance oil and gas pipelines is as follows: first, one or more pipelines are tailor-welded, and then the tailor-welded Pipeline groups are welded into long-distance oil and gas pipelines; the welding process relies on cranes to hoist the pipelines, and the mouth of the pipeline to be welded is manually aligned with the mouth of the target pipeline; this construction method is relatively backward, and the precision is low, and the construction process is relatively dangerous; The following issues urgently need to be resolved: ...

AI Technical Summary

Problems solved by technology

[0006] First of all, it cannot adapt to the target pipeline. In the field construction, the target pipeline is generally a fixed pipe and cannot be moved. The existing technology is mostly used for assembly welding of two movable pipes, which is not applicable to the problems in this welding.

[0007] Secondly, the clamping device is not adjustable, or only adjustable in one direction, and the applicability is low
