[0002] A wind turbine is a device that can convert wind energy into electrical energy. The wind turbine blades are the key components of a wind turbine. Their function is to convert wind energy into rotational kinetic energy and drive the generator to generate electricity. When the wind blows over the blades, the blades generate lift, and due to the special shape of the blades, the direction of the lift forms an angle with the direction of the wind, causing the blades to rotate and drive the generator to generate electricity.

[0003] Therefore, the main beam of the blade, as the supporting structure of the wind turbine blade, needs to have extremely high strength and installation accuracy. The deviation of the main beam will lead to uneven force distribution of the blade, and some parts may bear excessive loads, increasing the risk of stress and fatigue damage of the blade. However, the auxiliary tooling in the existing prior art cannot be adjusted and cannot adapt to the positioning and installation of blades of various specifications and sizes.

[0004] Therefore, a new wind turbine blade supporting device is needed, which can support and adjust the posture of the main beam during the installation of the wind turbine blade. Summary of the invention
