Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower mold hoisting, in particular to a hoisting device for hoisting a wind power tower mold. Background Art

[0002] Wind turbine towers are the masts that support wind turbines and absorb vibrations. Because they must withstand wind, earthquakes, and other environmental impacts, and must consider transportation requirements and costs, their structure and materials must be strictly controlled.

[0003] Wind turbine towers are assembled from several sections, each of which is further divided into several pieces. The tower mold is the foundation for each piece. The quality of the lifting equipment can affect the integrity of the components and the efficiency of the work.

[0004] At present, when hoisting wind turbine tower components, multi-point hoisting slings are mostly used. It is cumbersome to use the same sling for tower segments of different sizes, and workers need to repeatedly observe the balance point of the sling and the mold. If the slings for large-diameter segments and small-diameter segments are considered separately, more costs will be required. At the same time, the existing slings have many welded parts, high material costs, and are time-consuming and labor-intensive, which is not conducive to production. They are also inconvenient for workers to disassemble and are not conducive to the integrity of the components. In addition, when the existing slings are not in use, they cannot be placed on the ground without removing the shackles, which increases the workers' operating steps and makes it inconvenient for workers to disassemble. It is also not conducive to the integrity of the components, thereby wasting workers' working time, reducing their work efficiency and the utilization efficiency of the mold. In view of this, in-depth research on the above issues has led to the creation of this case. Utility Model Content

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hoist for hoisting wind turbine tower molds, comprising a crane hoisting plate, a mold hoisting plate, a limiting square tube, a rib plate and a floor support plate, the mold hoisting plate is arranged at the lower part of the crane hoisting plate, the rib plate is symmetrically welded on both sides of the mold hoisting plate and the crane hoisting plate along a certain interval, the floor support plate is welded at both ends of the mold hoisting plate and the crane hoisting plate, the limiting square tube is welded on both sides of the mold hoisting plate and the crane hoisting plate and is respectively welded and fixed to the rib plate and the floor support plate, the crane hoisting plate is symmetrically provided with lifting holes, and the mold hoisting plate is symmetrically provided with a number of connecting holes.

[0007] The mold hoisting plate and the crane hoisting plate are integrated structural steel plates.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] Example: In conjunction with the specification Figure 1It can be seen that the present application is to solve the problem that in the prior art, when hoisting wind turbine tower components, a multi-point hoisting sling is often used. It is cumbersome to use the same hoist for tower segments of different sizes, and workers need to repeatedly observe the balance point of the sling and the mold. If the slings for large-diameter segments and small-diameter segments are considered separately, more costs need to be invested. A sling for hoisting wind turbine tower molds is specifically designed, comprising a crane hoisting plate 1, a mold hoisting plate 2, a limiting square tube 3, a rib plate 4 and a ground support plate 5. The mold hoisting plate 2 is arranged at the lower part of the crane hoisting plate 1, and the rib plate 4 is provided on the ground support plate 5. The plate 4 is symmetrically welded on both sides of the mold lifting plate 2 and the crane lifting plate 1 along a certain interval, and the floor support plate 5 is welded at both ends of the mold lifting plate 2 and the crane lifting plate 1. The limiting square tube 3 is welded on both sides of the mold lifting plate 2 and the crane lifting plate 1 and is respectively welded and fixed to the rib plate 4 and the floor support plate 5. The crane lifting plate 1 is symmetrically provided with lifting holes 6, and the mold lifting plate 2 is symmetrically provided with several connecting holes 7; the mold lifting plate 2 and the crane lifting plate 1 are an integrated structural steel plate; the above-mentioned rib plate 4 is arranged to avoid the positions of the lifting holes 6 and the connecting holes 7.

[0014] The tower mold hoist is mainly welded by a crane lifting plate 1, a mold lifting plate 2, a limiting square tube 3, a rib plate 4 and a floor support plate 5. It uses general specification profiles and rib plates 4 for welding, which is convenient for workers to weld and use; and the hoist itself is equipped with a floor support plate 5, which can be placed directly on the ground without removing the shackle, reducing the number of operating steps for workers; the hoist greatly saves manpower, working time and materials, and facilitates production; at the same time, the hoisting of tower molds of different diameters can be achieved through a single hoist; the crane lifting plate 1 is provided with a lifting hole 6, which is used to connect with the crane lifting wire rope or sling hook: according to the crane lifting height and hook size The position and size of the lifting hole 6 are calculated according to the size of the mold and the load of the sling or wire rope; the above-mentioned mold lifting plate 2 is provided with a connecting hole 7, which is used to connect with the shackle used for suspending the upper part of the mold during the lifting operation: the holes are opened according to the range of the tower mold size, and the holes are opened at a spacing of 125mm. The hole diameter is larger than the corresponding shackle diameter selected according to the mold weight; the square tube is used as a bending, tensile and torsion-resistant profile to strengthen and bear the weight; the rib plate 4 plays a reinforcing and supporting role, and the position needs to avoid the lifting hole 6 and not hinder the insertion of the shackle, so as to facilitate hanging and lifting; the setting of the ground support plate 5 enables the sling to be placed on the ground without removing the shackle.
