Description

Technical Field

[0001] The utility model belongs to the field of welding auxiliary tools, in particular to an adjustable auxiliary pipe welding mobile trolley. Background Technique

[0002] With the continuous improvement of the urbanization rate and the requirements for energy conservation and environmental protection, the use of clean energy in thermal engineering has become a trend, and the use of waste heat from power plants for urban central heating has developed rapidly in recent years. Under this trend, there are more and more engineering constructions of municipal long-distance heat supply pipe networks.

[0003] In the engineering construction of municipal long-distance heat supply pipe networks, it is inevitable to carry out welding construction on pipes. There are many difficulties in actual welding construction. For example, when the pipe laying span is large, it is necessary to manually move the electric welding machine section by section. The electric welding machine is relatively heavy, and the manual moving method is time-consuming and laborious, bringing unnecessary difficulties to workers. At the same time, there are problems such as unevenness and small space at the bottom of the pipe trench, which not only makes it inconvenient to place the electric welding machine, but also very difficult to set up welding auxiliary measures in the pipe trench. Especially, pipe construction is generally in the open air, and there will be problems of water accumulation and mud in the pipe trench after rain, which poses a greater challenge to the placement and use of the electric welding machine. Therefore, solving the problems of inconvenient placement and movement of the electric welding machine is of great significance to the pipe welding project. Content of the Utility Model
