Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline welding, and particularly relates to a dust collector pipeline welding mechanism and a welding method. Background Art

[0002] In modern industrial production and municipal engineering construction, pipeline welding is a key technological process involved in fields such as energy transmission, chemical systems, water supply and drainage, etc.

[0003] Traditional high-altitude pipeline welding operations mainly rely on manual operation. Welders need to carry equipment and climb to high-altitude operation platforms, manually adjust the pipeline position and perform welding. However, such operation methods have significant defects: Firstly, the high-altitude operation environment has prominent safety hazards, and welders face occupational health risks such as falling and electric shock; secondly, the efficiency of manual welding is limited by the operator's technical level and physical conditions, the quality of welds fluctuates greatly, and defects such as pores and lack of fusion are likely to occur, resulting in a low qualified rate of non-destructive testing; thirdly, in complex working conditions (such as multi-angle connection of pipelines, staggered spatial layouts, etc.).

[0004] Existing fixing devices are difficult to achieve precise alignment and stable clamping of pipelines. During the welding process, the welds are likely to shift or have insufficient strength due to pipeline displacement, affecting the reliability of the overall structure. In addition, traditional equipment has a single function, lacking both automated feeding support for uninstalled pipelines and the ability to take into account the dynamic reinforcement of installed pipelines, further restricting the construction efficiency and quality. Therefore, there is an urgent need for a pipeline welding device with safety, high efficiency, and adaptability to solve the core problems such as high risk of high-altitude operation, unstable welding quality, and difficulty in complex angle docking in the prior art.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention
