Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbines, and particularly relates to a hoisting device for large wind turbine generator sets. Background Art

[0002] A wind turbine is a power device that converts wind energy into mechanical energy and then into electrical energy. Wind power generation utilizes natural energy, which can use the sun as a heat source and the atmosphere as a working medium for power generation. In a wind farm, a crane is used to lift large-sized components of a wind turbine. Through a series of operations such as moving, flipping, and positioning, the components are assembled together to form a wind turbine, which is an essential link in the installation of a wind turbine.

[0003] Existing hoisting devices generally use hoisting ropes to directly lift the components of a wind turbine. However, due to the large weight and volume of the components of a wind turbine, during multiple hoisting processes, the hoisting ropes are prone to wear. If only the hoisting ropes are replaced, it is easy to have an unstable interface, resulting in the situation of component shaking during hoisting. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for large wind turbine generator sets. Through the action of the mounting block, since the components of the wind turbine generator set are large in volume and heavy in weight, the device assembles the lifting beam and the sling part, which is convenient for timely replacement when the connection end of the sling wears. Moreover, the connection between the mounting groove and the mounting block is stable, and the assembly structure is simple, which is convenient for the staff to quickly replace it, thereby ensuring the stability of the hoisting process and solving the problem that when only the hoisting rope is replaced, it is easy to have an unstable interface, resulting in the situation of component shaking during hoisting.

Specific embodiment one

[0043] Please refer to Figures 1-8 , the present utility model is a hoisting device for a large wind turbine generator, including a suspension beam 1, installation grooves 2 are opened on both sides of the suspension beam 1, and installation blocks 3 are movably connected inside the installation grooves 2; a fixed plate 4 is fixed on the top of the installation block 3, and a plurality of reinforcement frames 5 are fixed on the top of the fixed plate 4; a plurality of slide grooves 6 are opened on the top of the suspension beam 1, slide blocks 7 are slidably connected inside the slide grooves 6, and a connection plate 8 is fixed on one side of the slide block 7; a handle 9 is fixed on the top of the connection plate 8, and a plurality of reinforcement rods 10 are fixed on one side of the connection plate 8; an iron block 11 is fixed on one side of the handle 9, a positioning plate 12 is fixed at one end of the slide groove 6, and a magnet 13 is fixed on one side of the positioning plate 12; the reinforcement rods 10 penetrate through the reinforcement frames 5, a suspension strap 14 is fixed on one side of the fixed plate 4, and a shackle 15 is fixed at one end of the suspension strap 14; first threaded holes 16 are opened on the top and side of the suspension beam 1, a plurality of second threaded holes 17 are opened on the surface of the fixed plate 4, and a plurality of third threaded holes 18 are opened on the surface of the reinforcement rods 10.

[0044] Specifically, the installation block 3 is of a "T" - shaped structure, and the installation block 3 matches the inner wall of the installation groove 2.

[0045] Furthermore, a fixing block 19 is fixed to the top of the hanging beam 1, and a lifting rope 20 is fixed to one side of the fixing block 19.

[0046] The operation process of this embodiment is as follows: When this device is in use, if hoisting is required, the mounting block 3 can be snapped into the mounting groove 2. After the "T"-shaped mounting block 3 is snapped into the mounting groove 2, the second threaded hole 17 on the surface of the fixing plate 4 corresponds to the first threaded hole 16 opened on the hanging beam 1. Then, pull the handle 9 to separate the iron block 11 on one side of the handle from the magnet 13 on one side of the positioning plate 12, so that the slider 7 can slide along the sliding groove 6. At this time, the reinforcing rod 10 on one side of the handle 9 is snapped into the reinforcing frame 5 on the fixing plate 4. At this time, the third threaded hole 18 on the reinforcing rod 10 is aligned with the corresponding second threaded hole, and bolts can be screwed into each threaded hole respectively to reinforce the mounting block 3. After the mounting block 3 is fixed, the hoisting operation can be carried out by using the sling 14 and the shackle 15.

At this time, the mounting plate 24 on one side of the counterweight block 23 faces the direction of several positioners 26. Pull the adjusting block 264, and the adjusting block 264 drives the clamping rod 265 to move outwards, pushing the mounting plate 24. When the mounting plate 24 is tightly attached to the outer wall of the counterweight shell 21, release the adjusting block 264. At this time, under the action of the spring 266, the spring 266 pushes the adjusting plate 263, and the adjusting plate 263 drives the clamping rod 265 to move. One end of the clamping rod 265 can be snapped into the through hole 25 on one side of the mounting plate 24.
