[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. In existing wind power generation, fan blades are erected at high altitudes through power generation towers, and the fan blades are rotated by the action of wind and converted into electrical energy.

[0003] During the construction of wind power generation equipment, it is necessary to weld the wind power generation tower. The existing tower welding method usually fixes the tower on the tooling, and the workers move the tower to weld the required welding positions.

The workers need to hold the welding equipment and move it continuously. In addition, due to the placement of some positions, the operating space is small, which makes it difficult to perform welding operations. This increases the difficulty in the welding process and cannot effectively improve the quality and efficiency of welding. Utility Model Content
