[0002] The stator support of a wind turbine is a structural component that fixes the stator core and windings, and is directly mounted on the generator frame or tower. It must not only bear the weight of the stator itself and electromagnetic forces, but also maintain long-term stability under extreme environments (such as strong winds, temperature differences, and vibrations) to ensure efficient generator operation.

[0003] The wind turbine stator support welding flipping fixture is a special equipment used to solve the flipping problem in the assembly and welding process of the stator support. Its core function is to achieve flat welding operation through horizontal flipping design, thereby reducing welding difficulty and improving quality.

[0004] The existing turning fixtures used for welding wind turbine stator supports require lifting the stator support with a hoisting device and placing it on the surface of a special turning device. After the stator support has completed the turning action, it needs to be lifted off the turning device again with a hoisting device. Such a cumbersome operation process will significantly reduce the turning efficiency of the stator support. Utility Model Content

[0005] The purpose of this utility model is to provide a flipping fixture for welding stator supports of wind turbine generators, which aims to solve the problem that in the prior art, the stator support needs to be lifted and placed on the surface of a special flipping device with the help of a lifting device, and after the flipping is completed, it needs to be lifted off the flipping device again with the lifting device. Such a cumbersome operation process will lead to a significant reduction in the flipping efficiency of the stator support.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flipping fixture for welding the stator support of a wind turbine generator, comprising a flipping support assembly, a clamping assembly and a flipping assembly, wherein a lifting assembly connected to the clamping assembly and used for height adjustment is installed on the top of the flipping support assembly, and a flipping assembly for flipping is installed on the side surface of the clamping assembly.

[0007] The flip support assembly includes a flip gantry and rollers, with rollers installed at the bottom of the flip gantry to enable movement.

[0008] As a preferred embodiment of the present invention, a tilting fixture for welding stator supports of wind turbine generators includes a lifting assembly comprising a hydraulic lift, a guide sleeve, and a guide rod. The hydraulic lift is installed on the top of the tilting gantry and connected to the clamping assembly.

[0009] As a preferred embodiment of the present invention, a flipping fixture for welding stator supports of wind turbine generators is provided, wherein a guide sleeve is connected through the top surface of the flipping gantry, and a guide rod connected to the upper surface of the lifting assembly is passed through the inside of the guide sleeve, and the guide sleeve and the guide rod are symmetrically arranged on both sides of the hydraulic lift.

[0010] As a preferred embodiment of the present invention, a flipping fixture for welding stator supports of wind turbine generators includes a clamping frame and telescopic rods, side plates, clamping plates, and rubber pads symmetrically arranged on both sides of the clamping frame. The clamping frame is connected to the movable end of a hydraulic lift. The telescopic rods are installed on the side surface of the clamping frame, and the movable end of the telescopic rods extends to the other side of the clamping frame. The movable end of the telescopic rods is connected to a side plate. The side surface of the side plate is connected to a clamping plate through the flipping assembly. The side surface of the clamping plate is connected to a rubber pad.

[0011] As a preferred embodiment of the present invention for a flipping fixture for welding stator supports of wind turbine generators, the clamping assembly further includes a guide rail connected to the bottom side of the clamping frame and a sliding groove opened on the top of the two side plates and adapted to the size of the guide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when the hydraulic lift extends and moves the two clamping plates of the clamping assembly to both sides of the stator support, the telescopic rod is activated. The telescopic rod extends and moves the rubber pad to the surface of the stator support through the side plates and clamping plates, thus achieving clamping and fixing of the stator support. Then, when the hydraulic lift retracts, it drives the stator support to move upward through the clamping assembly. Then, the drive motor drives the rotating shaft to rotate through the active bevel gear and the driven bevel gear.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a flipping fixture for welding stator brackets of wind turbine generators, including a flipping support assembly 100, a clamping assembly 200 and a flipping assembly 400. The top of the flipping support assembly 100 is equipped with a lifting assembly 300 connected to the clamping assembly 200 and used for height adjustment. The side surface of the clamping assembly 200 is equipped with a flipping assembly 400 for flipping.

[0023] The flip support assembly 100 includes a flip gantry 101 and rollers 102, with the rollers 102 mounted on the bottom of the flip gantry 101 to enable movement.

[0024] Preferably, the lifting assembly 300 includes a hydraulic lift 301, a guide sleeve 302, and a guide rod 303. The hydraulic lift 301 is installed on the top of the tilting gantry frame 101 and connected to the clamping assembly 200.

[0025] In practical use, when the hydraulic lift 301 extends, it can drive the clamping component 200 to move longitudinally, so that the height of the clamping component 200 can be adjusted to lift and adjust the wind turbine stator support on the ground.

[0026] Preferably, a guide sleeve 302 is connected through the top surface of the tilting gantry frame 101, and a guide rod 303 connected to the upper surface of the lifting assembly 300 is connected through the inside of the guide sleeve 302. The guide sleeve 302 and the guide rod 303 are symmetrically arranged on both sides of the hydraulic lift 301.

[0027] In practical use, when the clamping component 200 is subjected to a force, it can drive the guide rod 303 to slide inside the guide sleeve 302, which can limit the movement direction of the clamping component 200 and maintain its movement stability.

[0028] Preferably, the clamping assembly 200 includes a clamping frame 201 and telescopic rods 202, side plates 203, clamping plates 204 and rubber pads 205 symmetrically arranged on both sides of the clamping frame 201. The clamping frame 201 is connected to the movable end of the hydraulic lift 301. The telescopic rods 202 are installed on the side surface of the clamping frame 201 and the movable end of the telescopic rods 202 extends to the other side of the clamping frame 201. The movable end of the telescopic rods 202 is connected to the side plates 203. The side surface of the side plates 203 is connected to the clamping plates 204 through the flipping assembly 400. The side surface of the clamping plates 204 is connected to the rubber pads 205.

[0029] In practical use, when the telescopic rod 202 extends, it can squeeze the side plate 203 to move laterally. When the side plate 203 moves laterally, it can drive the rubber pad 205 to move laterally through the clamping plate 204, thereby realizing the clamping of the annular wind turbine stator support.

[0030] Preferably, the clamping assembly 200 further includes a guide rail 206 connected to the bottom side of the clamping frame 201 and a slide groove 207 formed on the top of the two side plates 203 and adapted to the size of the guide rail 206.

[0031] In practical use, when the side plate 203 is subjected to a force, it can drive the slide groove 207 to slide on the surface of the guide rail 206, which can limit the movement direction of the side plate 203 and maintain its movement stability.

[0032] Preferably, the flipping assembly 400 includes a bearing 401, a rotating shaft 402, a driven bevel gear 403, a drive motor 404, and a driving bevel gear 405. The side surfaces of the two side plates 203 are respectively fitted with bearings 401. The interior of each of the two bearings 401 is through a rotating shaft 402 connected to the two clamping plates 204. The ends of the two rotating shafts 402 are respectively connected to a driven bevel gear 403. The side surfaces of the two side plates 203 are respectively fitted with a drive motor 404. The output ends of the two drive motors 404 are respectively connected to a driving bevel gear 405 that meshes with the two driven bevel gears 403.

[0033] In practical use, when the drive motor 404 is running, it can drive the active bevel gear 405 to rotate. When the active bevel gear 405 rotates, it drives the driven bevel gear 403 to rotate through the meshing structure. When the driven bevel gear 403 rotates, it can drive the rotating shaft 402 to rotate inside the bearing 401. When the rotating shaft 402 rotates, it can drive the clamping plate 204 to rotate, thereby enabling the annular wind turbine stator support held by the clamping plate 204 to be flipped.

[0034] Working principle: When using the flipping fixture for welding the stator support of the wind turbine, the flipping gantry 101 can be moved by the roller 102 and the clamping assembly 200 can be moved to the top of the horizontally placed annular wind turbine stator support. Then, the hydraulic lift 301 can be operated. When the hydraulic lift 301 extends and moves the two clamping plates 204 of the clamping assembly 200 to both sides of the stator support, the telescopic rod 202 can be operated. When the telescopic rod 202 extends, it moves the clamping plates 204 closer to the stator support through the side plate 203. When the clamping plates 204 move the rubber pad 205 to the surface of the stator support, the stator support can be clamped and fixed.

[0035] Then the hydraulic lift 301 can be controlled to retract. When the hydraulic lift 301 retracts, it can drive the clamping component 200 to move upward and drive the stator bracket to move upward. When the stator bracket moves to the highest point, the drive motor 404 can be controlled. When the drive motor 404 runs, it can drive the rotating shaft 402 to rotate through the active bevel gear 405 and the driven bevel gear 403. The rotation of the rotating shaft 402 can drive the clamping plate 204 to rotate. When the clamping plate 204 drives the stator bracket to rotate 180°, the stator bracket can be flipped.

[0036] After the stator support is flipped, the hydraulic lift 301 can be extended and the stator support can be driven to move downward through the clamping assembly 200. When the stator support moves to the ground, the telescopic rod 202 can be retracted. When the telescopic rod 202 retracts, the clamping plate 204 can be driven to move away from the stator support through the side plate 203, thereby releasing the stator support.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
