Description

Technical Field

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

[0002] Pipe welding is a common metal joining method to connect two sections of pipes or pipes and fittings. This connection method is commonly used in industry, construction and piping systems.

[0003] When the existing pipeline welding device is used to weld the metal pipeline, the existing pipeline welding device often fixes the pipeline through a clamping device and welds it through a welding machine. However, due to its relatively fixed structure when welding the pipeline, the device can only weld half of the pipeline when welding the pipeline. When welding the other half of the pipeline, it is necessary to loosen the fixing structure and manually rotate the pipeline for secondary fixation before welding the lower half of the pipeline. This welding method not only takes a long time to weld, but also the welding points of the two pipelines are very easy to loosen during the rotation process, which greatly affects the welding effect of the pipeline.

[0004] Therefore, in order to solve the problems that when a pipeline welding device is welding a metal pipeline, it is difficult to perform circumferential welding on the four sides of the pipeline due to its welding structure, the half-and-half welding has a greater impact on the welding effect of the pipeline, and its detection structure has a poor fixing effect on the pipeline, a welding device for pipeline installation is developed. By adding a tooth transmission structure, a rotary welding structure and a limit fixing structure to the pipeline welding device, the effect of the device on the stable welding of the welding points of two pipelines can be greatly improved.
