Abstract
Description

[0002] As a clean and renewable energy, wind energy plays an increasingly important role in the development of energy in today's world. Wind turbine towers mainly play a supporting role in wind turbine generator sets. Wind turbine towers are assembled and welded by multiple single-section cylinders. The misalignment of adjacent cylinder sections and the welding quality of welds are crucial links that affect the bearing capacity and performance of wind turbine towers.
[0003] In the prior art, the bottom section of the wind turbine tower is usually connected to the tower section by a T-shaped flange, and the flange diameter exceeds the tower diameter; and the existing integral tower assembly device has a small adjustment range, making it difficult to assemble using the integral tower assembly device. Therefore, in actual operation, due to the large diameter and heavy weight of the T-shaped flange, the traditional hoisting assembly requires more manpower and time, resulting in low assembly efficiency, and the safety and assembly quality cannot be guaranteed.
[0004] In the prior art, due to the interference between the integral assembly device and the welding roller frame, the integral assembly device is difficult to be placed between two welding roller frames. When repairing and replacing the cylinder segments of wind turbine towers, sleepers or steel sections are generally used to pad the lower part of the cylinder body, and the steel sections are supported and welded to the cylinder body and fixed to the ground. Then, a carbon arc air gouging is used to cut off the weld between the cylinder segment to be replaced and the cylinder body, and finally a crane is used to replace the cylinder segment. However, the straightness and coaxiality of the cylinder replaced by this replacement method are difficult to guarantee, and multi-directional welding is used during welding, which has a great test on welding quality, welding efficiency and operation safety.
