The swing of the pressing block connecting rod 2 in the wind power blade demoulding method is driven by the movement of the elastic hoisting component 4, the pressing block connecting rod 2 does not bear the weight of the blade and transmit hoisting force, the upward movement displacement of the elastic hoisting component 4 determines the swing angle of the pressing block connecting rod, even if the pressing block component can be pressed on the blade to form self-locking, larger self-locking pressure can not be formed on the blade, the blade is effectively protected from being damaged by clamping in the demoulding process, and the reliability and the safety of the clamp are improved. Before the fixture is hoisted and demolded or after demolding and loading are completed, the pressing block assembly and the C-shaped seat are both in an initial period, the distance is the largest, the blade can smoothly and quickly enter and exit the fixture before and after demolding, and the blade demolding efficiency is improved. Pressing force of the pressing block on the blade in the pressing block assembly is adjustable, clamping force can be adjusted on the basis that the blade is not damaged according to clamping requirements, and safety of lifting and demolding is improved.
In the above, the technical solutions of the embodiments of the present invention are fully described, and it should be noted that the described embodiments are only some embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
