[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-2It can be seen that when the utility model is installed, the personnel first install the clamps 2 at the top and bottom of the tower 1. The clamps 2 can be made of steel sheets and fixed by screws. The installation is simple and convenient. The fixing plate 5 is fixed in advance and can be welded. A pair of parallel limiting ropes 6 are provided between the fixing plate 5 at the top of the tower 1 and the fixing plate 5 at the bottom. The limiting ropes 6 are tightened and fixedly connected to the fixing plates 5. One fixing method is that the end face of the fixing plate 5 is provided with a first screw 15, and the first screw 15 can squeeze against the limiting rope 6 to fix it. When installing the limiting rope 6, the movable plate 8 is set on the pair of limiting ropes 6 through the limiting hole 17. The movable plate 8 can move vertically on the limiting rope 6. The bearing plate 9 is connected to the movable plate 8. The best connection is detachable. During hoisting, the components of the wind turbine generator set are installed on the supporting plate 9 through the binding rope 12. The supporting plate 9 is connected to the four corners by multiple balancing ropes 11, and the upper end is connected to the hook 13. The external hoisting power source pulls the traction rope 14 and the hook 13 and the balancing rope 11 connected to the traction rope 14 to pull up the supporting plate 9. The external hoisting power source here is the existing technology. A winch set at the top of the tower 1 can be used, or a heavy crane can be used. The external hoisting power source here pulls the traction rope 14 in the vertical direction. When the supporting plate 9 is pulled upward, the limiting rope 6 limits the movable plate 8 and the supporting plate 9 connected to the movable plate 8, so that it can only move vertically and cannot shake in the horizontal direction. The hoisting is stable, the installation performance of the hoisting is improved, and it is accurately hoisted to the top of the tower 1, which is convenient for personnel to operate.

[0023] It should be noted that there are many parts in a wind turbine generator set, which requires multiple lifting operations. The clamp 2 is easy to install and can be retained. It can be used when replacing parts later by simply removing the limit rope 6. The drawings in this utility model specification are only schematic diagrams, and the dimensions and proportions in the drawings do not represent the actual dimensions and proportions.

[0024] Among them, an inserting plate 10 is provided on the side of the supporting plate 9 corresponding to the movable plate 8, and a socket 16 is opened at the position of the movable plate 8 corresponding to the inserting plate 10. The inserting plate 10 is inserted into the socket 16, and the inserting plate 10 and the socket are fixed by a second bolt 18, which is convenient for installation and disassembly.

[0025] Among them, the end face of the movable plate 8 is provided with a second screw 7, which can press against the limit rope 6 to fix it. Here, the second screw 7 serves to temporarily fix the movable plate 8. When the movable plate 8 is fixed during the hoisting process, personnel involved in high-altitude operations can press the second screw 7 against the limit rope 6 to fix the movable plate 8, so that the load-bearing plate 9 can be stopped in mid-air without traction. Of course, in this case, the selection of the limit rope 6, the connection of the clamp 2 and the fixed plate 5 are all highly demanding, and technicians need to pay attention. In the present utility model, under normal circumstances, the limit rope 6 only serves to limit the horizontal direction and does not perform traction work.

[0026] Among them, a reinforcing rib 4 is provided between the fixing plate 5 and the clamp 2 to further increase the stability of the connection between the fixing plate 5 and the clamp 2.

[0027] Among them, the limiting rope 6 is made of steel wire rope with high strength, and personnel can choose it according to experience and actual situation on site.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
