Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation equipment, and in particular relates to a supporting device for repairing a wind power generator. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine is generally composed of components such as a wind wheel, a power generation device, a direction regulator, a tower, a speed limit safety mechanism and an energy storage device. The wind wheel rotates under the action of wind. The generator rotor is the rotating part of the generator. When there is a problem with the rotor, it needs to be repaired. Due to the large size and mass of the rotor, it is very difficult to transport it, and it is also inconvenient to rotate it, causing inconvenience in maintenance work.

[0003] In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN216490149U. When in use, the generator rotor needs to be placed on a bracket, and then the bracket needs to be pushed to drive the generator rotor to move to a clamping position for clamping. However, the bracket and the maintenance platform are directly installed, so that the generator rotor is in rigid contact with the bracket when placed on the bracket. Due to the large volume and mass of the generator rotor, the impact of the generator rotor on the bracket is relatively strong when it is placed, which makes it easy for the bracket to be subjected to a large impact and be damaged. In addition, the bracket is prone to damage the surface of the generator rotor, which is not conducive to the maintenance and use of the generator rotor. Utility Model Content

[0004] The utility model aims to provide a support device for wind turbine maintenance, aiming to solve the technical problem in the prior art that the generator rotor has a large impact with the maintenance platform when placed, resulting in easy damage to the maintenance platform and the generator rotor surface.

[0005] The utility model is implemented as follows: a support device for wind turbine maintenance comprises a base, a lifting plate is arranged on the base, an adjusting component for driving the lifting plate to move up and down is arranged on the base, a top plate is arranged on the lifting plate, a plurality of groups of elastic members distributed at intervals are fixedly mounted on the lifting plate and the top plate, two groups of support shafts distributed in parallel are rotatably mounted on the top plate, and support blocks for supporting the top plate are fixedly mounted on both ends of the base.

[0006] Further technical solution: a plurality of sets of first telescopic rods spaced apart and distributed in parallel are fixedly mounted on the base, and ends of the plurality of first telescopic rods away from the base are fixedly connected to the lifting plate.

[0007] Further technical solution: A plurality of sets of second telescopic rods spaced apart and distributed in parallel are fixedly mounted on the lifting plate, and ends of the plurality of second telescopic rods away from the lifting plate are fixedly connected to the top plate.

[0008] Further technical solution: a bracket is fixedly installed on the top plate, a screw is threadedly installed on the bracket, the screw points to the rotating axis of one group of support shafts, and a pressure plate is fixedly installed on the end of the screw.

[0009] Further technical solution: The adjustment assembly includes a screw, a connecting plate and a rotating plate. The screw is rotatably installed on the base and drives two groups of moving blocks to move in opposite directions at the same time. Two groups of rotating plates are provided and are located at both ends of the screw. The rotating plate is rotatably installed on the base and is used to push the lifting plate to move. The rotating plate and the moving block on the same side are rotatably connected together with a group of connecting plates, and a worm is provided on the base to drive the screw to rotate.

[0010] Further technical solution: A support cylinder is rotatably mounted on one end of the rotating plate away from the base, and the support cylinder is in rolling contact with the lifting plate.

[0011] A further technical solution is as follows: the worm is rotatably mounted on the base and is eccentrically perpendicular to the lead screw, and the worm is meshed with a worm wheel fixedly mounted on the lead screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. When the rotor of the generator contacts the support shaft, the compression deformation of the elastic member is used for buffering, thereby avoiding direct rigid contact between the rotor of the generator and the support shaft, reducing the impact of the rotor of the generator when it is placed, and avoiding impact damage to the outer surface of the rotor of the generator.

[0014] 2. After the generator rotor is placed, the top plate is rigidly supported by the support block to improve the stability of the top plate and the generator rotor during subsequent maintenance. At the same time, the lifting plate continues to move downward until the compression deformation of the elastic part is completely released. At this time, the elastic part is in the original length state. During subsequent maintenance, the elastic part no longer maintains a continuous compression state, thereby increasing the service life of the elastic part. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-Figure 4 As shown, a support device for wind turbine maintenance provided by the utility model comprises a base 1, a lifting plate 3 is arranged on the base 1, a plurality of groups of first telescopic rods 2 spaced apart and distributed in parallel are fixedly installed on the base 1, one end of the plurality of first telescopic rods 2 away from the base 1 are fixedly connected to the lifting plate 3, an adjusting component 19 for driving the lifting plate 3 to move up and down is arranged on the base 1, a top plate 12 is arranged on the lifting plate 3, a plurality of groups of second telescopic rods 13 spaced apart and distributed in parallel are fixedly installed on the lifting plate 3, one end of the plurality of second telescopic rods 13 away from the lifting plate 3 are fixedly connected to the top plate 12, a plurality of groups of elastic members 11 spaced apart and distributed are fixedly installed together with the lifting plate 3 and the top plate 12, two groups of support shafts 14 distributed in parallel are rotatably installed on the top plate 12, and support blocks 18 for supporting the top plate 12 are fixedly installed at both ends of the base 1.

[0023] In actual application of this embodiment, the lifting plate 3 is pushed upward by the adjusting component 19, so that the top plate 12 is away from the supporting block 18, and the movement of the lifting plate 3 is guided by the first telescopic rod 2. At this time, the rotor of the generator can be placed on the supporting shaft 14, and the rotor of the generator is supported by two sets of supporting shafts 14. After the rotor of the generator is placed on the supporting shaft 14, it will press down the top plate 12 under the action of its own gravity. The top plate 12 moves downward to compress the elastic member 11. Finally, the top plate 12 is stably supported by the elastic member 11. When the rotor of the generator contacts the supporting shaft 14, the compression deformation of the elastic member 11 is used for buffering, thereby avoiding direct rigid contact between the rotor of the generator and the supporting shaft 14, reducing the impact of the rotor of the generator when it is placed, and avoiding impact damage to the outer surface of the rotor of the generator. After the rotor of the generator is placed stably, the adjusting assembly 19 drives the lifting plate 3 to move downward stably. At this time, the top plate 12 moves downward with the lifting plate 3, and finally the top plate 12 contacts the support block 18. At this time, the top plate 12 is rigidly supported by the support block 18, so as to improve the stability of the top plate 12 and the generator rotor during subsequent maintenance. After the top plate 12 contacts the support block 18, the lifting plate 3 continues to move downward until the compression deformation of the elastic member 11 is completely released. At this time, the elastic member 11 is in the original length state. During subsequent maintenance, the elastic member 11 no longer maintains a continuous compression state, thereby increasing the service life of the elastic member 11. After that, the rotor of the generator can be repaired. During maintenance, the support shaft 14 can be rotated by driving the handle at the end of one set of support shafts 14, so that the rotor of the generator can be rotated to a suitable angle, which is convenient for the maintenance and use of the rotor of the generator.

[0024] In an example of this embodiment, the elastic member 11 is a spring, and of course it can also be other elastic components such as an elastic ball. The top plate 12 is supported by the spring, thereby achieving buffering when the generator rotor is placed.

[0025] like Figure 1 , Figure 2 As shown, a support device for repairing a wind turbine provided by the utility model is provided. A bracket 15 is fixedly mounted on a top plate 12. A screw 16 is threadedly mounted on the bracket 15. The screw 16 points to the rotation axis of one group of support shafts 14. A pressure plate 17 is fixedly mounted on the end of the screw 16.

[0026] In actual application of this embodiment, when the support shaft 14 drives the generator rotor to rotate to a suitable angle, the screw 16 is rotated. The screw 16 drives the pressure plate 17 to contact the rotating axis of the support shaft 14, thereby fixing the support shaft 14, avoiding the rotation of the support shaft 14 during subsequent maintenance of the generator rotor, and improving the stability during subsequent maintenance.

[0027] like Figure 1 , Figure 2As shown, a support device for wind turbine maintenance provided by the utility model is provided. The adjustment component 19 includes a screw 4, a connecting plate 6 and a rotating plate 7. The screw 4 is rotatably installed on the base 1 and drives two groups of moving blocks 5 to move in opposite directions at the same time. Two groups of rotating plates 7 are provided and are located at both ends of the screw 4. The rotating plates 7 are rotatably installed on the base 1 and are used to push the lifting plate 3 to move. The rotating plates 7 and the moving blocks 5 on the same side are rotatably connected with a group of connecting plates 6. A worm 9 for driving the screw 4 to rotate is provided on the base 1.

[0028] Specifically, in order to make the rotating plate 7 push the lifting plate 3 to move more smoothly, a support tube 8 is rotatably mounted on one end of the rotating plate 7 away from the base 1 , and the support tube 8 is in rolling contact with the lifting plate 3 .

[0029] Specifically, the worm 9 is rotatably mounted on the base 1 and is skewed and perpendicular to the lead screw 4 . The worm 9 is meshed with a worm wheel 10 fixedly mounted on the lead screw 4 .

[0030] When this embodiment is actually used, the handle at the end of the worm 9 drives the worm 9 to rotate, and the worm 9 drives the lead screw 4 to rotate through the meshing worm wheel 10, so that the lead screw 4 can simultaneously drive the moving blocks 5 on both sides to move inward or outward at the same time. When the moving block 5 moves inward, it drives the rotating plate 7 to rotate inward through the connecting plate 6, so that the height of the support tube 8 is reduced at this time, and the lifting plate 3 moves downward. When the moving block 5 moves outward, the height of the support tube 8 rises and pushes the lifting plate 3 to move upward, thereby realizing the lifting and lowering control of the lifting plate 3, and the stability of the position of the lifting plate 3 is guaranteed by the self-locking of the worm 9 and the worm wheel 10.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
