Description

Technical Field

[0001] The present application belongs to the technical field of slings, and in particular to a sling that facilitates the flipping of wind power blades. Background Art

[0002] A hoist is a device used to lift heavy objects in lifting machinery. It is an important component of lifting machinery. The selection of a hoist should be based on factors such as the weight, shape and material of the object to be lifted to ensure the safety and efficiency of the lifting operation. A wind turbine blade is a large part used in wind power generation. A complete wind turbine blade is generally assembled from a blade main shaft and three independent blades. Its lifting operation generally requires the use of a safer hoist in conjunction with a crane to carry out.

[0003] The utility model with the existing authorization announcement number CN217708821U discloses a wind turbine blade hoisting and flipping adjustment hanger, which effectively clamps one end of the wind turbine blade in the positioning ring by extending one end of the wind turbine blade into the positioning ring, and then cooperates with the driving component and the positioning hook to make the hook on the positioning hook extend into one end of the root of the wind turbine blade, effectively fix the other end of the wind turbine blade, and effectively keep the wind turbine blade in a vertical state, and then through the setting of the power component, the driving wheel drives the connecting plate and the positioning ring to deflect synchronously, and further makes the wind turbine blade in the positioning ring deflect synchronously, which is easy to install. The hanger of this scheme is simple to operate and can effectively prevent the wind turbine blade from slipping under the action of weight, thereby ensuring the safety of its operation and further improving the work efficiency.

[0004] Although the above-mentioned technical solution solves the problems of difficulty in hoisting and bundling operations of wind turbine blades and easy slipping, the above-mentioned technical solution blocks the installation head of a single blade by means of positioning hooks and positioning rings, which is not convenient for assembling a single blade after flipping it, and its flipping direction and flipping range are relatively limited. It can only perform a right-angle flip in a single direction along the axis of the blade, and lacks a flipping auxiliary structure that is convenient for multi-directional and large-angle flipping. As a result, the flipping direction and flipping angle of a single blade are relatively limited and inconvenient to use.

[0005] To this end, we propose a hanger that facilitates the flipping of wind turbine blades to solve the above problems. Utility Model Content
