[0002] With the promotion of new energy technologies, wind power generation, as a new energy technology, has the characteristics of clean and pollution-free, large single-unit capacity, good economic and social benefits, and is one of the new energy sources with the greatest development potential. The tower is an important supporting structure of a wind turbine. Common tower structures include concrete towers and steel towers. The concrete tower is an important supporting structure in a wind turbine and is usually made of concrete. The concrete tower has high strength and stability, and can withstand the load of wind turbines and strong winds to ensure the safe operation of the unit. The concrete tower has good durability, can withstand the erosion of the natural environment and the impact of climate change, and maintain the stability and safety of the structure for a long time. The manufacturing cost of the concrete tower is relatively low, and it has a long service life, so it has good economy. In addition, the concrete tower can adapt to different terrain and climatic conditions, and can be built and operated in various complex environments.

[0003] Existing concrete towers usually use a prestressed anchor structure. The prestressed anchor structure is to embed the anchor in the concrete foundation, and the bottom tower is connected to the concrete foundation through the embedded anchor. The rigidity of the connection part is ensured by applying prestress to the anchor. When installing the existing prestressed anchor, the anchor is usually lifted by hoisting equipment, and the upper and lower ends of the anchor are manually installed into the upper anchor plate and the lower anchor plate in turn. Since the length of the anchor unit of the existing concrete tower exceeds 3m and the weight usually exceeds 100KG, manual installation is adopted, which not only has low construction efficiency, but also has safety hazards. Therefore, it is necessary to propose an auxiliary installation device for prestressed anchors. Utility Model Content
