Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and more specifically, to an acetylene pipeline welding device. Background Technology

[0002] During the installation and positioning of acetylene gas pipelines, welding equipment is required to weld the pipeline ends to facilitate the positioning and laying of the pipeline and make it easier to transport and use acetylene.

[0003] The utility model patent with authorization announcement number CN 218487644 U discloses a pipeline welding positioning fixture, relating to the field of pipeline welding. To address the limitation of existing positioning devices, which can only weld one type of steel pipe and are difficult to weld at the bottom of the pipe, this pipeline welding positioning fixture includes a base. A mounting plate is vertically mounted on the upper left side of the base, and a rotating mechanism is mounted on the mounting plate. A fixing mechanism is mounted on the side of the rotating mechanism away from the mounting plate. An installation groove is formed on the upper surface of the base, and an adjustment mechanism is mounted at the bottom of the groove. The adjustment mechanism has a clamping mechanism. This pipeline welding positioning fixture facilitates the fixing of steel pipes of different sizes, improving the practicality of the device. It facilitates welding at the bottom of the steel pipe, making it more convenient to use and improving the efficiency of pipeline welding. The limiting rod makes the moving block more stable during movement, preventing wobbling and ensuring more stable fixing of the steel pipe, thereby improving welding quality.

[0004] In the aforementioned disclosed structure, the pipe is positioned by clamping the structure and then aligned and welded. This method can only weld the pipe separately before laying and installing it. It cannot be directly aligned and welded to the pipe on-site for circumferential welding. The accuracy and stability are poor, and it cannot be aligned and welded along the pipe end position. The adaptability is insufficient and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an acetylene pipeline welding device. This device connects a semi-circular positioning ring and a semi-circular guide ring via a semi-circular support ring, allowing for separate installation and positioning. This facilitates fitting the pipeline for installation and use. Furthermore, the device allows for combined installation and positioning by threading an adjusting threaded rod and welding head onto a mounting block at one end of the adjusting frame. This enables welding to be performed by rotating the device around the pipeline end, resulting in precision, efficiency, ease of on-site operation, and high adaptability.
