AI Technical Summary
When lifting wind turbine blades, the blades are prone to swaying due to the wind, which can lead to unstable power transmission and affect the ease of installation.
An adjustable lifting device was designed, including a crossbar, grippers, a traction rope, an L-shaped rod, and a telescopic sleeve. The grippers hold the blades, and the stability of the blades is maintained by the pulling of the traction rope and the rotation of the L-shaped rod. The position of the grippers is adjusted by the extension and retraction of the telescopic sleeve to ensure a smooth conveying process.
This ensures the stability of the blades during lifting and transportation, improving the convenience and safety of installation.
