Technical Field

The utility model relates to the technical field of wind power blade lifting tools, in particular to an integrated lifting tool for a prefabricated blade root strip steel flange of a wind power blade.

Background

At present, most wind power blade forming processes all adopt blade root prefabrication forming processes, prefabricated blade roots need to be lifted and assembled, because pneumatic shapes of various wind power blade designs are inconsistent, the gravity center positions of the prefabricated blade roots of the wind power blades of different models are different, the existing prefabricated blade root lifting tool is basically only suitable for wind power blades of specific models, and is difficult to be compatible with various models, tools corresponding to different models need to be replaced when wind power blades of different models are produced, so that the investment of tool cost is increased, and resource waste is caused.

Disclosure of Invention

The utility model aims to provide an integral hoisting tool for a strip steel flange of a prefabricated blade root of a wind power blade so as to solve the problem that hoisting tools for prefabricated blade roots of different blade profiles cannot be compatible.

In order to achieve the above object, the basic scheme of the present utility model is as follows: the utility model provides a wind-powered electricity generation blade prefabricated blade root belted steel flange integrative frock of lifting by crane, includes lifting plate, connecting plate, shackle and two clamp splice, lifting plate and connecting plate vertical fixation, be equipped with a plurality of lifting holes on the lifting plate, the shackle can be dismantled and connect on arbitrary lifting hole, two the clamp splice cross-section is "n" type, two the bottom at the connecting plate is fixed to the clamp splice, be equipped with the bolt hole on the clamp splice, bolt hole department can be dismantled and be connected with bolt, nut.

The basic scheme has the beneficial effects that: the prefabricated blade root and the clamping blocks are fixed by bolts and nuts, the shackle is installed in the lifting hole suitable for the gravity center of the prefabricated blade root of the blade profile according to the blade profile, the lifting tool of the prefabricated blade root shared by different blade profiles can be realized, and the input cost of part of tools caused by switching between the models is reduced.

Further, a plurality of reinforcing ribs are arranged between the top surface of the clamping block and the connecting plate. The stability of the connection of the clamping blocks and the connecting plates is improved.

Further, the lifting plate and the connecting plate are both steel plates, and the lifting plate is welded with the connecting plate. The steel plate has high strength, is more suitable for hoisting, and the hoisting plate and the connecting plate are welded so that the connection of the hoisting plate and the connecting plate is firmer.

Further, the lifting plate, the connecting plate and the clamping blocks are all provided with chamfers. And the wind power blade or workers are prevented from being scratched by sharp corners.

Further, the lifting plate is L-shaped, a plurality of lifting holes are formed in the horizontal section of the lifting plate, a strip-shaped groove is formed in the lower portion of the vertical section of the lifting plate, and the connecting plate is fixed in the strip-shaped groove. So that the connection between the connecting plate and the lifting plate is more stable. .
