[0004] When the stator bracket is turned over by the conventional method, it is turned over by a hoisting crane. However, when using a hoisting crane, the site problem needs to be considered, and two hooks need to cooperate for operation. Through the lifting holes on the core shaft connecting piece of the outer shaft body on the stator bracket, the stator bracket is turned over by a lifting device. However, when facing the turnover requirements of stator brackets of different sizes, corresponding models of core shaft connecting pieces need to be selected. When deflecting, it is easy to cause the reset position to shift after inspection because the core shaft connecting piece and the outer shaft body of the stator bracket are not in full contact, affecting the normal use of the stator bracket.

[0030] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0031] Embodiment 1

[0032] Refer to Figure 1-6, which is the first embodiment of the present utility model, provides a turnover tooling for the stator support of a semi-direct drive wind turbine generator. This turnover tooling for the stator support of a semi-direct drive wind turbine generator includes a base 1 and a stator support body 2. The stator support body 2 is located at the top of the base 1. A positioning component 3 is arranged at the top of the base 1. The positioning component 3 is connected to the base 1 through a flipping component 4. The positioning component 3 includes a clamping component 31 and a locking component 32. The clamping component 31 and the locking component 32 are respectively distributed at both ends of the stator support body 2. The clamping component 31 includes a sleeve 311. One end of the sleeve 311 close to the stator support body 2 is fixedly installed with a protective cover 312. A clamping block 313 is movably connected inside the protective cover 312. The clamping blocks 313 are distributed in a circular array around the sleeve 311. A threaded slip ring 314 is movably connected to the outside of the sleeve 311. A connecting shaft 315 is hinged to the outside of the threaded slip ring 314. The threaded slip ring 314 is connected to the clamping block 313 through the connecting shaft 315, and the connecting shaft 315 corresponds to the clamping block 313 one by one. A threaded shaft 316 is also arranged in the sleeve 311. The threaded slip ring 314 is in threaded fit connection with the threaded shaft 316. One end of the threaded shaft 316 is connected to the output shaft of a motor 317. The motor 317 is fixedly installed at the end of the sleeve 311 away from the protective cover 312. A reinforcing shaft for preventing tipping is fixedly installed on the outside of the base 1. The stator support body 2 is a prior art and is mainly divided into an inner shaft body and an outer shaft body, providing protection for the stator. The sleeve 311 is a hollow cylindrical shape, and one end close to the stator support body 2 is provided with a rubber gasket for reducing wear. The diameter of the protective cover 312 is larger than the maximum diameter of the stator support body 2, providing protection when the stator support body 2 is flipped. The clamping block 313 can move inward or outward with the center of the sleeve 311 as the center within the limit of the protective cover 312, so as to complete the adaptation and fixing requirements for stator support bodies 2 of different sizes. The inner side of the threaded slip ring 314 is provided with threads adapted to the threaded shaft 316, and when the threaded shaft 316 rotates, it moves along the groove in the sleeve 311. By restricting the movement of the inner shaft body in the stator support body 2 through the sleeve 311, and through the extrusion of the clamping block 313, the adaptation of the outer shaft body of the stator support body 2 of different sizes is completed. Thus, when the stator support body 2 deflects, the stator support body 2 is not easily misaligned and offset after resetting.

[0033] A first lifting ear 318 is fixedly installed on the outside of the sleeve 311. The first lifting ear 318 is arranged at the end of the sleeve 311 away from the protective cover 312. A lifting hole for lifting equipment is opened on the first lifting ear 318. Through the lifting hole, one end of the stator support body 2 located in the sleeve 311 can be lifted.

[0034] A first flip frame 319 is provided on the top of the base 1. The top of the first flip frame 319 is fixedly mounted on the outside of the protective cover 312. The first flip frame 319 provides support for the stator bracket body 2 restricted by the sleeve 311 in the protective cover 312, so that the stator bracket body 2 is in a suspended state when in the placed state.

[0035] The locking member 32 includes a load-bearing ring 321, which is located at one end of the stator support body 2 away from the sleeve 311. A locking ring 322 is hingedly connected to the bottom of the load-bearing ring 321. The load-bearing ring 321 and the locking ring 322 are threadedly connected via a locking bolt 323. The locking ring 322 can be deflected and opened under the restriction of the load-bearing ring 321 to be assembled to one end of the stator support body 2. The locking bolt 323 can adjust the tightness between the load-bearing ring 321 and the locking ring 322, thereby fixing them to the stator support body 2.

[0036] A second lifting ear 324 is fixedly installed on the top of the locking ring 322, and a second flip frame 325 is fixedly installed on the bottom of the load-bearing ring 321. The first lifting ear 318 is provided with a lifting hole for lifting equipment, through which one end of the stator support body 2 located in the load-bearing ring 321 can be lifted. The second flip frame 325 provides support for the stator support body 2 on the load-bearing ring 321, and cooperates with the first flip frame 319 to complete the support of the stator support body 2 as a whole, so that the stator support body 2 remains stable when it is not flipped.

[0037] The flip member 4 includes a column 41, which is fixedly mounted at both ends of the base 1. A rotation slot 42 is provided on the top of the column 41. The column 41 is movably hinged to the first flip frame 319 and the second flip frame 325 through the rotation slot 42. The column 41 raises the stator support body 2 so that one end of the stator support body 2 is not easily in contact with the ground when the stator support body 2 is deflected. When the stator support body 2 is flipped at either end, the rotation slot 42 is used as the center of the circle.

[0038] A positioning groove 43 is further provided at the end of the column 41 facing away from the base 1. The positioning groove 43 is located at the bottom of the protective cover 312 and is adapted to the clamping block 313. When the first flip frame 319 deflects the transfer groove 42 in the column 41 as the center of the circle, the corresponding clamping block 313 is fully engaged with the positioning groove 43, thereby fixing the clamping block 313 on the base 1, thereby preventing the stator bracket body 2 from loosening and falling off when placed.

[0039] Before the hoisting preparation work, by feeding one end of the stator bracket body 2 into the sleeve 311, the inner shaft body of the stator bracket body 2 is in full contact with the silica gel washer in the sleeve 311. After reaching the maximum moving distance, the output shaft of the motor 317 drives the threaded shaft 316 to rotate, so that the threaded slip ring 314 connected by threads moves along the groove in the sleeve 311, thereby changing the deflection angle of the connected coupling shaft 315, and making the clamping block 313 move inwardly centered on the center of the sleeve 311, so as to complete the fixation requirement for the outer shaft body in the stator bracket body 2 of different sizes. Thus, when the stator bracket body 2 deflects, the stator bracket body 2 is not easily displaced and offset after reset. At the same time, by placing the bearing ring 321 at one end of the stator bracket body 2 away from the sleeve 311 and buckling the hinged locking ring 322, and adjusting the tightness through the locking bolt 323 connected by threads, the locking ring 322 is fixed at one end of the stator bracket body 2. The hook of the hoisting equipment cooperates with the second lifting lug 324 to make the stator bracket body 2 deflect with the rotating groove 42 where the first turning frame 319 is located as the center, or cooperate with the first lifting lug 318 to make the stator bracket body 2 deflect with the rotating groove 42 where the second turning frame 325 is located as the center, so as to meet the different angle turning requirements of the stator bracket body 2. When the stator bracket body 2 is in a non-deflected state, the overall height of the stator bracket body 2 is raised by the column 41 to prevent the stator bracket body 2 from contacting the ground during turning, and the clamping block 313 is clamped with the positioning groove 43 on the column 41, so as to fix the position of the clamping block 313 on the base 1, so that the stator bracket body 2 is not easily loosened and fallen off when placed.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
