[0002] The wind turbine tower is the tower pole for wind power generation. The production of wind turbine tower is generally completed in the production workshop, during which welding technology is required. The flange is welded first, and then the weld is non-destructively tested and the flatness is checked, sandblasted, painted, etc. After the internal parts are installed and the finished product is inspected, it is transported to the installation site before it can be transported to the site for installation. When welding the wind turbine tower in the workshop, since the wind turbine tower is relatively heavy, it needs to be transferred with the help of lifting equipment.

[0003] In the prior art, when hoisting and transferring a tower, the tower is generally tied and fixed by a lifting rope, and then lifted and transported. In practical applications, there are some shortcomings: it is very inconvenient to use the lifting rope to tie and fix the tower, and the tower is cylindrical and not easy to tie. During hoisting and transportation, the lifting rope is easy to shake, and the tower will also shake, which is easy to collide with surrounding objects, which is not safe enough. Therefore, improvements are needed. Utility Model Content
