AI Technical Summary
Conventional self-climbing wind power maintenance cranes are prone to causing wear and tear on the tower surface when handling heavy materials, which requires increased fixing force when the self-climbing robot climbs, affecting the stability and safety of the equipment.
The system employs a rope-pulling structure, including a support arm, a rotating rod, a winding frame, a motor, a limiting plate, and an auxiliary frame. The motor drives the rotating rod to rotate and wind up the rope. Combined with the limiting plate and support wheels, this reduces the fixing force between the self-climbing robot and the tower, avoids direct contact, and improves stability.
It effectively reduces wear and tear on the self-climbing robot and the tower, improves the stability and safety of the equipment, reduces the amount of manual operation, and enhances the usage effect.
