Wind power blade demoulding hoisting clamp and wind power blade demoulding method

Abstract

The invention provides a wind power blade demoulding hoisting clamp. The wind power blade demoulding hoisting clamp comprises a C-shaped seat, a pressing block connecting rod obliquely arranged and installed on the C-shaped seat in a swinging mode and a pressing block assembly installed at the lower end of the connecting rod and used for compressing a blade on the C-shaped seat. The wind power blade demoulding hoisting clamp is characterized by further comprising an elastic hoisting assembly capable of driving the pressing block connecting rod to swing, the elastic hoisting assembly is movablyinstalled on the C-shaped seat and enables the initial spacing between the pressing block assembly and the C-shaped seat to be the largest through an initial oblique angle of an elastic positioning pressing block connecting rod, the blade extends between the C-shaped seat and the pressing block assembly, blade gravity is located on the C-shaped seat with the upward hoisting of the elastic hoisting assembly, and the pressing block connecting rod swings downwards with the hoisting of the elastic hoisting assembly to enable the spacing between the pressing block assembly and the C-shaped seat tobe reduced and pressed on the blade. According to the wind power blade demoulding hoisting clamp, the blade is effectively protected from being damaged in the demoulding process due to clamping, thereliability and safety of the clamp are improved, the demoulding efficiency of the blade is improved, and the service life is long.

Description

technical field [0001] The invention relates to a wind power blade stripping lifting fixture and a wind power blade stripping method, and belongs to the technical field of wind power blade stripping. Background technique [0002] At present, wind turbine blades are mostly hoisted by slings and ordinary slings. Because the slings or slings cannot effectively clamp the lifted blades, sometimes slings will appear during the air transfer process after the blades are lifted. Or the situation that the spreader and the lifting blade are tripped, once the blade is tripped and falls from the air, it will damage the blade and hit the equipment or personnel below, causing a major safety accident, which is extremely unsafe. [0003] The existing blade root lifting fixture is a C-shaped seat. Since the distance between the C-shaped seat is generally greater than the thickness of the blade root and does not have a self-locking function, there is a risk of the blade slipping during the dem...

Problems solved by technology

[0002] At present, wind turbine blades are mostly hoisted by slings and ordinary slings. Because the slings or slings cannot effectively clamp the lifted blades, sometimes slings will appear during the air transfer process after the blades are lifted. Or when the sling is disconnected from the lifting blade, once the blade is disconnected and falls from the air, it will damage the blade and hit the equipment or personnel below, causing major safety accidents, which is extremely unsafe

[0003] The existing blade root lifting fixture is a C-shaped seat. Since the distance between the C-shaped seat is generally greater than the thickness of the blade root and does not have a self-locking function, there is a risk of the blade slipping during the demoulding process.

In the self-locking process, if the self-locking force is too large, and the contact surface between the fixture and the wind turbine blade is relatively small, the wind turbine blade, as a kind of FRP material, is relatively brittle and may easily cause crush damage
