[0001] This utility model relates to the field of welding tooling technology, and in particular to an auxiliary device for welding ultra-long and ultra-heavy pipelines. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles.

[0003] During pipeline laying, pipes need to be welded together on-site. For ultra-long and ultra-heavy pipelines, the welding posture cannot be adjusted manually. Therefore, hoisting machinery is generally required to transfer the pipes to welding supports or to adjust the pipe posture directly during welding. Since this is an outdoor operation, the hoisting machinery is often powered by an internal combustion engine, and the noise and vibration generated may affect the welding operation. Furthermore, the use of this equipment increases construction costs. Utility Model Content
