Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a pipeline welding device. Background Art

[0002] A pipeline is a device connected by pipes, fittings, and valves for transporting gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of uses, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] After searching, it was found that the Chinese patent with announcement number CN221910348U discloses a ventilation duct welding device, including a welding assembly and a pipe fixing assembly; the two groups of pipes are placed in the two groups of pipe rotating grooves respectively, the connection points of the two groups of pipes are closely aligned, and the bidirectional electric screw is started to make the two sliding columns slide relative to each other, driving the pipe rotating groove to move relative to each other, so that the pipe rotating groove is close to the pipe wall of the pipe, and at the same time, the rod tube inside the bidirectional fixing rod is continuously shortened as the two sliding columns approach each other. When the pipe rotating groove is close to the pipe wall of the pipe, the bidirectional fixing rod is tightened, so that the upper end of the sliding column is tightened, so that the two groups of pipes are fastened to the pipe rotating groove, and then the movable welding machine is adjusted left and right and up and down to align the movable welding machine with the tight connection of the two groups of pipes. By being able to rotate the two groups of pipes in the pipe rotating groove during welding, the welding of one circle at the connection can be completed.

The smoke can cause harm to nearby workers, and the increased temperature may cause burns to workers.

[0006] Therefore, those skilled in the art provide a pipeline welding device to solve the problems raised in the above background technology. Utility Model Content
