Description

Technical Field

[0001] The utility model relates to the technical field of wind power generator sets, in particular to a hanger balancing device and a wind power generator set hoisting structure. Background Art

[0002] At present, the transmission chain, gearbox, generator and other components of wind turbines involve single-hook lifting, steering and other requirements during the assembly, lifting and transportation lifting processes.

[0003] When hoisting under this condition, since the center of gravity of the hoisted object is generally biased to one end (the center of gravity of the hoisted object is not in the center), the mountain-shaped hook tilts due to the different pulling forces on both sides. At this time, the rotating bearing of the mountain-shaped hook is subjected to a huge eccentric load, which will cause abnormal wear of the bearing during the rotation of the mountain-shaped hook. In extreme cases, bearing failure or even safety accidents may occur, which greatly shortens the life of the crane and poses a major safety hazard. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a hoisting device balancing device and a wind turbine generator set hoisting structure, which can effectively solve the problem that when hoisting components such as the transmission chain, gear box and generator of the current wind turbine generator set, the center of gravity is biased to one end, which is easy to damage the crane and poses a great safety risk.

[0005] Another purpose of the utility model is to provide a wind turbine generator set hoisting structure.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A sling balancing device comprises a balancing block, a first shackle assembly, a second shackle assembly and a third shackle assembly, wherein the top of the balancing block is connected to a U-shaped hook via the first shackle assembly, and the left and right ends of the bottom of the balancing block are respectively connected to the left and right ends of a suspended object via the second shackle assembly and the third shackle assembly, and the tension on both sides of the U-shaped hook is balanced by the balancing block to prevent the U-shaped hook from tilting.

[0008] Furthermore, three through holes for installing the first shackle assembly, the second shackle assembly and the third shackle assembly are processed on the balancing block, and the three through holes are distributed in an equilateral triangle.

[0009] Furthermore, the balancing block is in the shape of an equilateral triangle with rounded corners.

[0010] Furthermore, the first shackle assembly, the second shackle assembly and the third shackle assembly each include a shackle and a sling.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] like Figure 1 , Figure 2 As shown, this embodiment provides a sling balancing device, including a balancing block 1, a first shackle assembly 2, a second shackle assembly 3 and a third shackle assembly 4. The top of the balancing block 1 is connected to the mountain hook 6 through the first shackle assembly 2, and the left and right ends of the bottom of the balancing block 1 are connected to the left and right ends of the suspended object 5 through the second shackle assembly 3 and the third shackle assembly 4 respectively. The first shackle assembly 2, the second shackle assembly 3 and the third shackle assembly 4 all include shackles and slings.

[0023] Due to the different tensions on the two side straps below the balance block 1, the balance block 1 is in a tilted state. However, for the straps above the balance block 1, since the tensions on both sides of the straps are the same, the mountain-shaped hook 6 is still in a balanced state. The balance block 1 converges the resultant forces in three directions at one point. At this time, the tensions on both sides of the mountain-shaped hook 6 are equal, achieving the purpose of vertical lifting and solving the tilting problem.

[0024] like Figure 3 , Figure 4 As shown, the balancing block 1 is processed with three through holes 101 for installing the first shackle assembly 2, the second shackle assembly 3 and the third shackle assembly 4, and the three through holes are distributed in an equilateral triangle. Further, the balancing block 1 is an equilateral triangle structure with rounded corners.

[0025] The installation method of the balancing device of the sling in this embodiment is as follows:

[0026] The upper end of the balancing block is hung on the mountain-shaped hook through the first shackle assembly, and the left and right ends of the bottom of the balancing block are connected to the left and right ends of the hoisted object (such as a transmission chain) through the second shackle assembly and the third shackle assembly respectively. After the installation of the balancing device is completed, the hoisting can be carried out.

[0027] Embodiment 2:

[0028] This embodiment provides a wind turbine generator set hoisting structure, including the hoisting device balancing device described in Example 1.

[0029] The hoist balancing device and hoisting structure of this embodiment are not only suitable for the hoisting of wind turbines, but are also applicable to other hoisted objects when the hoisting conditions occur. It is highly practical and has a wide range of applications.
