Abstract

The invention provides a butt-joint ring welding device used for new energy natural gas pipeline mounting, and relates to the technical field of natural gas pipeline welding. The problems that in thenatural gas pipeline butt joint process, although existing welding devices can rotate pipelines to achieve welding in the welding process, in the rotating process, welding seams can be possibly torn once the rotating speed of the pipeline at one end deviates, the rotating welding manner is prone to being influenced by welding wire winding, and in addition, in the welding process, due to the fact that the depth of welding seams cannot be controlled easily, leaking points are extremely prone to happening are solved. The butt-joint ring welding device comprises a base; and a lifting table is in fixed butt joint to the front end of the base. In the butt-joint ring welding device, due to the fact that antiskid wheels are rotationally mounted at the positions, corresponding to jacking mechanisms, on rotating pressing mechanisms, it can be guaranteed that natural gas pipelines at the left end and the right end can rotate synchronously in the rotating process, and welding seams are prevented from being torn.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline welding, in particular to a butt girth welding device used for the installation of new energy natural gas pipelines. Background technique [0002] Pipelines that transport natural gas (including associated gas produced in oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. Using natural gas pipelines to transport natural gas is the only way to transport natural gas in large quantities on land. [0003] Existing natural gas pipeline welding machine such as a natural gas pipeline welding machine in patent application CN201711160487.X, its structure includes pipeline locking structure, welding head handle, welding controller, welding button, welding ring fixing rod, welding ring, motor, Fixed plate, transmission, rotating seat, support rod, cross rod, welding clip, fixed ring, connecting ro...
