[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a wind turbine blade lifting device having the following features:

[0015] Beneficial effects:

[0016] The design of the bearing seat of the wind turbine blade lifting device enables the support frame to flexibly adjust the angle according to the movement of the transportation equipment, especially when turning, effectively reducing the lateral force on the blade and protecting the blade from unnecessary stress damage;

[0017] The first telescopic mechanism cooperates with the design of the tooth column and the gear ring. When the wind turbine blades need to be stored for a long time, the tooth block can be used to press against the gear ring to limit its rotation and increase stability. The meshing of the iron column driven by the second telescopic mechanism and the tooth column further strengthens the locking effect. Combined with the application of the electromagnetic lock, even in the event of external collision, it can ensure that the support frame and the blades are stable and immobile, greatly reducing the risk of accidental damage.

[0018] The use of electromagnetic locks consumes electricity only when locking and unlocking, and does not consume electricity at other times. It is both energy-saving and environmentally friendly. Its quick response characteristics simplify the operating process and improve transportation efficiency, especially in cases of frequent loading and unloading or when emergency braking is required, it can quickly ensure the safety of the blades.
