Description

Technical Field

[0001] This application relates to the field of impeller disassembly, and in particular to a tooling table for disassembling multi-stage impellers of wind turbines. Background Technology

[0002] The impeller is the core power component of a wind turbine. Its structure typically consists of a disc, blades, and a shaft sleeve, and it is primarily responsible for converting mechanical energy into the kinetic and pressure energy of the fluid, thereby driving the efficient transport of gas. Because the impeller operates under high-speed rotation, alternating loads, and complex media environments for extended periods, its structural components are prone to wear, corrosion, or fatigue damage. Therefore, regular disassembly, maintenance, or replacement is necessary to ensure the safe and reliable operation of the wind turbine system.

[0003] For larger wind turbines, disassembly tools are often required. Specifically, the disassembly tool is connected to the impeller, and then the reaction force drives the impeller shaft, causing the impeller and shaft to loosen from each other, thus allowing for disassembly of the impeller. Existing disassembly tools are cumbersome to connect to the impeller, resulting in low disassembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling table for disassembling multi-stage impellers of wind turbines, which can improve the disassembly efficiency of impellers.

[0009] Preferably, the force-bearing rod is further provided with a clamping bolt, one side of which can abut against the clamping claw.

[0010] Preferably, the jacking assembly includes a jack and an extension rod. The output end of the jack is connected to the force-bearing platform, and the output end of the jack is provided with a jack head. The extension rod is connected to the jack head.

[0011] Preferably, the receiving assembly includes a telescopic rod disposed on the tooling table and a net bag disposed on the top of the telescopic rod, the net bag being located below the pushing assembly.

[0012] Preferably, the telescopic rod includes a lower rod fixed to the tooling table and an upper rod slidably connected to the lower rod; a spring is connected between the lower rod and the upper rod, the lower rod has a vent hole, and the net is connected to the top of the upper rod.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0025] This application discloses a tooling table for disassembling multi-stage impellers of a wind turbine.

[0026] A tooling table for disassembling multi-stage impellers of a wind turbine includes a tooling table 1. Two support rods 11 are mounted on the tooling table 1. A handle 5 is detachably connected to the top of each support rod 11. The support rods 11 have connecting grooves 52, and a connecting rod 51 is fixed to the handle 5, with the connecting rod 51 inserting into the connecting groove 52. Rollers are provided at the bottom of the tooling table 1. The handle 5 helps the operator push the tooling table 1. A clamping assembly 2 is also provided on the support rods 11. The handle 5 is detachable, allowing the clamping assembly 2 to be easily removed from the support rods 11. This allows the clamping assembly 2 to work independently without relying on the tooling table 1 (e.g., ...). Figure 4 As shown in the image, this is mainly because the fan is too high, and the tooling platform cannot be raised to a suitable height. This is one of the possible solutions.

[0027] The clamping assembly 2 is also equipped with a pushing assembly 3. The clamping assembly 2 includes a force-bearing platform 21, a force-bearing rod 24, a clamping jaw 26, and a clamping bolt 27. The force-bearing platform 21 is slidably connected to the support rod 11. The force-bearing platform 21 includes two force-bearing plates 22 and a force-bearing bolt 23 for connecting the two force-bearing plates 22. A clamping area exists between the two force-bearing plates 22, and part of the force-bearing rod 24 is located within this area. The force-bearing bolt 23, through the engagement of a nut, allows the force-bearing plates 22 to clamp the force-bearing rod 24. The force-bearing rod 24 has a threaded section, and the clamping jaw 26 is slidably mounted on the force-bearing rod 24. The clamping bolt 27 can rotate on the threaded section of the force-bearing rod 24. After the clamping jaw 26 abuts against the impeller of the fan, the pushing assembly 3 is placed between the force-bearing plate 22 and the impeller shaft. Then, the clamping bolt 27 is rotated, and the clamping jaw 26 presses against the impeller. The force-bearing rod 24 is also fixed with an anti-detachment part 25, the size of which is larger than the distance between the two force-bearing plates 22. When the clamping bolt 27 is tightened, the clamping jaw 26 abuts against the impeller, and the anti-detachment part 25 abuts against the force-bearing plate 22. This makes the force-bearing rod 24 a tensioned two-force rod. At the same time, both sides of the pushing assembly 3 are abutted by the force-bearing plate 22 and the shaft of the impeller, respectively, making the pushing assembly 3 a compression two-force rod. When the clamping assembly 2 works alone, such as Figure 4 As shown, the tension bolt 23 can be connected at the original position where the support rod passes through to clamp the two load-bearing plates. At this time, two tension bolts 23 are needed to improve the clamping effect of the load-bearing platform 21 on the load-bearing rod.

[0028] The jacking assembly 3 includes a jack 31 and an extension rod 32. The output end of the jack 31 is connected to the force-bearing platform 21, and a jack head is provided at the output end of the jack 31. The extension rod 32 is connected to the jack head. The extension rod 32 allows the jack 31 to indirectly abut against the impeller shaft. If the jack head can directly abut against the impeller shaft, the extension rod 32 is not needed. The jack head is a detachable design, which can be used for different bore diameters on the impeller shaft.

[0029] The tooling table 1 is also equipped with a receiving assembly 4; the receiving assembly 4 includes a mesh bag 47 and four telescopic rods 41, all of which are mounted on the tooling table 1. Each telescopic rod 41 includes a lower rod 42 fixed to the tooling table 1 and an upper rod 43 slidably connected to the lower rod 42; a spring 44 connects the lower rod 42 and the upper rod 43, and the lower rod 42 has a vent hole 45. A hook 46 is fixed to the upper rod 43. The mesh bag 47 is rectangular, and its four corners are connected to the hooks 46. The mesh bag 47 is located below the pushing assembly 3.

[0030] The implementation principle of this embodiment is as follows: After the clamping assembly 2 and the pushing assembly 3 connect the impeller and the impeller shaft, the jack 31 is driven, and the jack 31 pushes against the impeller shaft through the extension rod 32. As the jack 31 pushes, the impeller and the impeller shaft will loosen. At this time, it is convenient for the staff to disassemble the impeller, and the extension rod 32 will fall freely and be caught by the net bag 47. In this application, the base of the jack 31 is fixedly connected to one of the force plates 22. In other embodiments, it may not be fixedly connected. In this case, when the impeller and the impeller shaft are loosened, both the jack 31 and the extension rod 32 will fall freely onto the net bag 47, thus not interfering with the impeller on the impeller shaft. It also makes it convenient for the staff to disassemble the impeller.

[0031] Because the gripper of this application can slide on the force-bearing rod, the working depth of the gripper is relatively large, thus allowing for the disassembly of impellers deep within the impeller shaft. Furthermore, the force-bearing rod can be adjusted in position within the clamping area, resulting in a relatively large working width of the gripper, enabling the clamping of larger impellers. Through the rational use of working depth and working width, the gripper can disassemble different impellers of the same fan, thereby achieving the disassembly of multi-stage impellers.

[0032] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
