[0002] In wind power generation equipment, the tower serves as the main support for the wind turbine, and its installation quality directly affects the working efficiency and safe operation of the wind turbine. With the development of wind power technology, the size and specifications of towers used in different wind power projects have become increasingly diverse. The overall tower supporting the wind turbine is assembled from multiple tower sections on the ground and then installed on the tower foundation using hoisting equipment. The assembly of multiple tower sections on the ground is carried out on horizontal tooling supports. The tooling supports for the tower sections must be compatible with the outer diameter of the cylindrical tower. Towers with different outer diameters require tooling supports of specific sizes, increasing the construction costs for the construction unit. How to develop a universal combined tooling support that can be suitable for towers of various outer diameters, thereby reducing construction costs and improving tower assembly efficiency, has become a problem that needs to be solved on-site.
