[0009] Furthermore, a positioning hole is provided on the fixing plate, and the end of the high-speed shaft is plugged into the positioning hole and fixedly connected to the fixing plate by bolts.

[0010] Furthermore, the plurality of threaded holes are arranged near an end of the connecting beam crossbar away from the fixing plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This patent connects the fixed plate through an L-shaped connecting beam, so that the end of the high-speed shaft is connected to the fixed plate through bolts, and then different lifting points are selected according to the center of gravity of the hoisted object, and the universal rotating lifting ring is threadedly connected to the threaded hole corresponding to the lifting point. The universal rotating lifting ring is hung by the crane hook to make the high-speed shaft achieve overall balance when dismantled, so that the high-speed shaft can be lifted, disassembled and replaced conveniently and labor-savingly, and the tooling has a simple structure, is easy to produce and process, and has low cost. In addition, when using the tooling of this patent, the lifting point has high balance, is easy to use, saves manpower, and can meet the needs of rapid disassembly and replacement of the high-speed shaft of the gear box in the cabin.

[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0018] The utility model discloses a novel wind power generation gearbox high-speed shaft disassembly tool, the main structure comprises an L-shaped connecting beam 1, a fixing plate 2 is arranged on the outer side of the vertical rod of the connecting beam 1, the end of the high-speed shaft is detachably connected to the fixing plate 2 by bolts, the end of the cross rod of the connecting beam 1 is far away from the connecting end of the high-speed shaft and the fixing plate 2, a plurality of threaded holes 3 are arranged in an array evenly spaced on the cross rod of the connecting beam 1, a universal rotating lifting ring 4 is threadedly connected to one of the threaded holes 3, and a lifting device, each threaded hole 3 represents a balance lifting point, and the universal rotating lifting ring 4 can be installed by selecting the threaded holes 3 corresponding to different lifting points according to the center of gravity of the lifting object, so that the high-speed shaft can reach a balanced state by hooking the universal rotating lifting ring 4 for lifting during disassembly, which can save manpower and improve loading and unloading efficiency, and the lifting point of the tool has high balance, which can meet the requirements of rapid disassembly and replacement of the high-speed shaft of the gearbox in the cabin.

[0019] Preferably, the connecting beam 1 and the fixing plate 2 are detachably connected via bolts, so that a suitable fixing plate 2 can be easily replaced according to different specifications of the high-speed shaft.

[0020] Preferably, the fixing plate 2 is provided with a slot 5 which is slidably plugged into the vertical rod of the connecting beam 1. After the connecting beam 1 is plugged into the slot 5, it is detachably connected to the fixing plate 2 by bolts, which is convenient for fixing the relative position of the connecting beam 1 and the fixing plate 2, preventing the relative position of the fixing plate 2 and the connecting beam 1 from changing during the lifting and disassembly process, thereby ensuring stability during lifting.

[0021] Preferably, a positioning hole 6 is provided on the fixed plate 2. After the end of the high-speed shaft is inserted into the positioning hole 6, it is fixedly connected to the fixed plate 2 by bolts. This can limit the installation position of the high-speed shaft and ensure stability during the lifting process. At the same time, it plays a positioning role in the installation of the high-speed shaft and can achieve rapid connection between the high-speed shaft and the fixed plate 2, thereby improving work efficiency.

[0022] Preferably, the plurality of threaded holes 3 are arranged near a position of the cross bar of the connecting beam 1 away from one end of the fixed plate 2, and the cross bar of the connecting beam 1 is located directly above the high-speed shaft, so that the space occupied by the cross bar of the connecting beam 1 and the high-speed shaft overlaps, which can occupy less working area and enable the hanging point and the installation point of the high-speed shaft to achieve a better balance state.

[0023] This patent can make the high-speed shaft achieve overall balance when dismantled, so the high-speed shaft can be lifted, disassembled and replaced conveniently and labor-savingly, and the tooling structure is simple, easy to produce and process, and has low use cost. In addition, when using the tooling of this patent, the lifting point has high balance, is easy to use, saves manpower, and can meet the needs of rapid disassembly and replacement of the high-speed shaft of the gearbox in the cabin.
