The operator can control the position of the hydraulic propulsion rod by operating the hydraulic handle, and use the top block to contact the generator to lift and fix the generator to the left and right. At the same time, the position of the tooling hook can be changed by rotating the threaded rod so that it is aligned and fixed with the lower frame. While inserting the tooling hook, press the connecting rod to fix the tooling hook to prevent displacement when the threaded rod rotates. This simple tooling design can improve work efficiency and safety, ensure the stable connection and correct centering of the generator, and is suitable for the maintenance and repair of wind turbine generator sets.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides Figure 1-4 A simple tool for centering a wind turbine generator set shown in FIG. 1 includes a fixing frame 1 and a connecting frame 3 arranged at a middle position on the upper side of the fixing frame 1;

[0031] The fixing holes 2 are respectively opened at the inner positions of the four corners of the fixing frame 1, and the hydraulic propulsion rod 5 is connected to the inner position of the upper side of the connecting frame 3. The left end of the hydraulic propulsion rod 5 is connected to the hydraulic handle 4, and the upper side of the right end of the hydraulic propulsion rod 5 is provided with a top block 6;

[0032] A threaded rod 7 is connected to the interior of the lower side of the connecting frame 3, and handles 8 are respectively provided at the left and right ends of the threaded rod 7, and a tool hook 9 is connected to the lower left side of the threaded rod 7;

[0033] Four fixing blocks 13 are respectively arranged at the outer positions of the four corners of the lower right side of the tooling hook 9, a connecting rod 10 is connected to the upper position of the fixing block 13, and a fixing bolt 11 is arranged at the connection position between the connecting rod 10 and the fixing block 13;

[0034] A pulley 12 is provided at the middle inner position of the lower right side of the tooling hook 9 , and a rotating shaft 15 is provided at the connection position between the pulley 12 and the tooling hook 9 .

[0035] In this embodiment, when the operator is centering the generator, the rear tooling is required to support the generator to prevent the generator from tilting backward after the four anchor bolts of the generator are loosened. When the generator is centered, the left and right tooling still needs to be adjusted, and the equipment can be used to fix the left and right. First, the tooling hook 9 is hooked into the gap of the lower frame, and at the same time, the hydraulic handle 4 is turned to push the hydraulic propulsion rod 5 to the left and right ends of the rear side of the generator, and the top block 6 is used to contact the generator to lift and fix the generator to the left and right. In this process, the fixed frame 1 plays a supporting role with the lower frame, and the tooling hook 9 plays a fulcrum role. At the same time, the operator can change the position of the tooling hook 9 on the threaded rod 7 so as to better align and fix it with the lower frame.

[0036] like Figure 1-4As shown, the four fixing blocks 13 are connected to the tooling hook 9 by an integrated connection method, and the height and thickness of the four fixing blocks 13 are equal. The fixing bolts 11 are connected and fixed to the connecting rod 10 and the fixing block 13 by a threaded connection method. The length of the connecting rod 10 is longer than the length of the tooling hook 9. The tooling hook 9 is connected to the threaded rod 7 by a threaded connection method. The threaded rod 7 is connected to the connecting frame 3 by a threaded connection method, and the threaded rod 7 can be moved left and right on the connecting frame 3 by screwing the thread. The hydraulic propulsion rod 5 is connected by an integrated connection method. It is connected to the connecting frame 3, the hydraulic propulsion rod 5 is specifically a hydraulic sleeve rod setting, the top block 6 is connected to the hydraulic propulsion rod 5 through an integrated connection method, the connecting frame 3 is connected to the fixed frame 1 through an integrated connection method, and the fixed frame 1 and the connecting frame 3 are respectively composed of metal materials, the rotating shaft 15 is connected to the pulley 12 through an integrated connection method, and a slide rail 14 is provided at the connecting position of the rotating shaft 15 and the tooling hook 9, the pulley 12 is specifically a sixteen-sided equilateral polygon, and the pulley 12 can move left and right on the inner side of the tooling hook 9 through the rotating shaft 15.

[0037] Preferably, when the operator uses the tooling hook to insert into the gap of the frame below, the pulley 12 can be set to better perform the insertion operation. The pulley 12 is an equilateral hexagon and is made of metal material. It has the characteristics of high strength, which helps the hook 9 to be better inserted and slid out. When the operator inserts the tooling hook into the gap of the frame, the two connecting rods 10 can be pressed to fix the tooling hook to prevent the tooling hook from being displaced while the threaded rod 7 rotates.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
