[0002] Wind turbine blades are the core components that convert wind energy into mechanical energy. Their appearance is similar to that of an airplane wing. Through aerodynamic design, the upper surface is convex and the lower surface is relatively flat. The pressure difference is generated by the flow velocity difference between the upper and lower surfaces when wind blows through, driving the blades to rotate. The blades are usually composed of a blade root, a blade body and a blade tip. Wind turbine blade installation auxiliary tools refer to mechanical equipment used to assist in blade installation.

[0003] During the installation of wind turbine blades, existing technologies have significant technical bottlenecks. The lack of effective fixing points at the blade ends makes installation and docking operations extremely difficult. In particular, when inserting the bolts on the blades into the hub, it is difficult to manually accurately control their position and angle due to the large size and heavy weight of the blades. In addition, the blades have no reliable fixed fulcrums, which makes it very easy for them to shake and deviate during installation fine-tuning.
