Anti-corrosion natural gas pipeline laying and welding auxiliary device

Abstract

The invention relates to the technical field of natural gas pipeline welding, in particular to an anti-corrosion natural gas pipeline laying and welding auxiliary device. The anti-corrosion natural gas pipeline laying and welding auxiliary device comprises a supporting seat, and a lifting structure is arranged in the supporting seat; a limiting structure is arranged between the lifting structure and the supporting seat; the side face of the supporting seat is connected with a guide structure; a moving structure is arranged on the bottom side of the guide structure; a clamping and fixing structure is arranged on the top side of the guide structure; and a connecting structure is connected between the clamping structure and the guide structure. The overall stability of the auxiliary device is guaranteed through the lifting structure, the stability of the supporting seat is further guaranteed through the limiting structure, lifted pipelines are preliminarily positioned through the guide structure, alignment between the pipelines is facilitated, guiding and position calibration are conducted on the lifted natural gas pipelines through the moving structure, the pipelines have better stability in the position calibration process through the clamping and fixing structure, shaking between the structures is avoided through the connecting structure, and meanwhile installation is convenient.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline welding, in particular to an anti-corrosion natural gas pipeline laying welding auxiliary device. Background technique [0002] Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is the main way of natural gas transport on land. In the laying of natural gas pipelines, in addition to the corrosion resistance of the natural gas pipeline itself, it is also necessary to ensure the neat butt joint of the pipeline connections during the welding process of the natural gas pipeline, to ensure the tightness inside the pipeline and the tightness of the pipeline itself. Shock resistance. [0003] However, when connecting natural gas pipeli...

Problems solved by technology

[0003] However, when connecting natural gas pipelines, in order to facilitate the welding between pipelines, it is usually necessary to lift the pipelines to be connected by lifting equipment to ensure that the pipeline connection surface is suspended above the ground. It is difficult to connect accurately. Because the pipe on one side is in the state of being lifted, it is difficult for workers to calibrate, which reduces the welding efficiency. At the same time, the external ground environment is uneven, and it is inconvenient to raise the pipe. way, it is also inconvenient to move the hoisted pipeline
