AI Technical Summary
In existing wind turbine rotor locking devices, the metal contact surface between the positioning rod and the guide sleeve is too rigid, which makes it impossible for the locking screw to effectively fix the rotor, making it easy to loosen or increase rotor damage.
The system employs a combination structure of hydraulic cylinder, positioning rod, and locking component. Hydraulic control causes the guide sleeve to be fitted onto the outside of the positioning rod, and the axial positioning of the positioning rod is achieved through threaded locking adhesive and locking component, ensuring a fixed connection at both ends.
This improves the stability and reliability of impeller locking, reduces the possibility of positioning rod loosening, and lowers the probability of impact damage to the guide sleeve.
