[0001] This utility model relates to the field of wind turbine impeller disassembly and assembly technology, specifically a wind turbine impeller quick disassembly and assembly device. Background Technology

[0002] As the core component of a wind turbine generator set, the wind turbine impeller plays a crucial role. It directly withstands wind force and converts wind energy into mechanical energy to drive the generator. The design and manufacturing quality of the impeller directly affects the efficiency, reliability, and service life of the wind turbine generator. Typically, a wind turbine impeller consists of multiple blades designed using aerodynamic principles to maximize wind energy capture. The size, shape, and material selection of the impeller must undergo precise calculations and experimental verification to ensure stable and efficient operation under various wind conditions.

[0003] In the existing process of disassembling and assembling wind turbine impellers, most operations still rely on manual labor and lack effective alignment methods. Due to insufficient alignment, the disassembly and assembly speed is slow and prone to misoperation, thereby reducing the efficiency and quality of wind turbine impeller disassembly and assembly. To solve the above problems, we propose a rapid disassembly and assembly device for wind turbine impellers. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a quick assembly / disassembly device for a wind turbine impeller includes a movable base 1. Two L-shaped guide blocks 10 are slidably connected to one side of the movable base 1. A clamping assembly is provided on one side of the movable base 1 to move the two L-shaped guide blocks 10. A column 12 is slidably connected to the top of the movable base 1. A displacement assembly is provided on the top of the movable base 1 to move the column 12. A movable plate 16 is slidably connected to one side of the column 12. A lifting assembly is provided on one side of the column 12 to move the movable plate 16. A positioning block 17 is fixedly connected to one side of the movable plate 16. Two push plates 19 are slidably connected to one side of the movable plate 16 and outside the positioning block 17. Two telescopic electric cylinders 18 are fixedly installed on one side of the movable plate 16. The output ends of the two telescopic electric cylinders 18 pass through the movable plate 16 and are fixedly connected to the two push plates 19 respectively.

[0018] During the installation of the fan impeller, the mobile base 1 (which is equipped with a power carrier to provide power support for the controller and electrical equipment) is first moved to the installation area. Then, the clamping assembly drives the two clamping plates 11 to move on one side of the mobile base 1 to clamp the external fan and ensure the stability of the mobile base 1. The fan impeller is then placed outside the positioning block 17. Next, the lifting assembly drives the movable plate 16 to move on one side of the column 12 to align the fan impeller with the external fan. Then, the displacement assembly drives the column 12 to move on top of the mobile base 1, thereby bringing the fan impeller closer to the external fan. At the same time, the controller activates the two telescopic electric cylinders 18, which push the two push plates 19 to move outside the positioning block 17, thereby pushing the fan impeller into the interior of the external fan. Finally, the fan impeller is fixed with external bolts, thus completing the installation of the fan impeller.

[0019] When the fan impeller is removed, the external bolts are first removed to release the fan impeller from its fixation. Then, the positioning block 17 is used to support the fan impeller. Finally, the displacement component is used to move the column 12 to the top of the moving base 1 and move the fan impeller out of the fan, thus completing the removal of the fan impeller and improving the efficiency and quality of the fan impeller removal and assembly.

[0020] like Figures 1-4 As shown, the clamping assembly includes a first fixing plate 5 and a second fixing plate 6. Both the first fixing plate 5 and the second fixing plate 6 are fixedly connected to one side of the movable base 1. A bidirectional lead screw 7 is rotatably connected between the first fixing plate 5 and the second fixing plate 6. Two L-shaped guide blocks 10 are threadedly connected to the outer side of the bidirectional lead screw 7. One side of the two L-shaped guide blocks 10 is fixedly connected to two clamping plates 11 respectively. A turntable 8 is rotatably connected to one side of the first fixing plate 5. One end of the turntable 8 passes through the first fixing plate 5 and is fixedly connected to the bidirectional lead screw 7. A handle 9 is fixedly connected to one side of the turntable 8.

[0021] By pushing the handle 9 to drive the turntable 8 to rotate, and driving the bidirectional lead screw 7 to rotate between the first fixed plate 5 and the second fixed plate 6, the two L-shaped guide blocks 10 are driven to move the two clamping plates 11 on one side of the movable base 1, thereby improving the stability of the disassembly and assembly device.

[0022] like Figures 1-4 As shown, the displacement assembly includes a displacement groove 2, which is opened on the top of the movable base 1. A displacement threaded rod 3 is rotatably connected between the inner walls of the displacement groove 2. A displacement block 20 is threadedly connected to the outer side of the displacement threaded rod 3. The top of the displacement block 20 is fixedly connected to the column 12. A displacement motor 4 is fixedly installed on one side of the movable base 1. The output end of the displacement motor 4 extends into the interior of the displacement groove 2 and is fixedly connected to the displacement threaded rod 3.

[0023] The displacement motor 4 drives the displacement threaded rod 3 to rotate between the inner walls of the displacement groove 2, thereby driving the displacement block 20 to move the column 12 on the top of the movable base 1, thus improving the disassembly and assembly efficiency of the fan impeller.

[0024] like Figures 1-4 As shown, the lifting assembly includes a lifting groove 13, which is opened on one side of the column 12. A lifting threaded rod 14 is rotatably connected between the inner walls of the lifting groove 13. A lifting block 21 is threadedly connected to the outer side of the lifting threaded rod 14. One side of the lifting block 21 is fixedly connected to the movable plate 16. A lifting motor 15 is fixedly installed on the top of the column 12. The output end of the lifting motor 15 extends into the interior of the lifting groove 13 and is fixedly connected to the lifting threaded rod 14.

[0025] The lifting motor 15 drives the lifting threaded rod 14 to rotate between the inner walls of the lifting groove 13, and drives the lifting block 21 to move the movable plate 16 on one side of the column 12, thereby improving the accuracy of the fan impeller disassembly and assembly.

[0026] This utility model provides a quick-release and installation device for a fan impeller. The specific working principle is as follows: When installing the fan impeller, firstly, the movable base 1 (which has a power carrier to provide power support for the controller and electrical equipment) is moved to the installation area. Then, by pushing the handle 9, the turntable 8 is rotated, driving the bidirectional lead screw 7 to rotate between the first fixed plate 5 and the second fixed plate 6. Simultaneously, the two L-shaped guide blocks 10 drive the two clamping plates 11 to move on one side of the movable base 1, thereby clamping the external fan and ensuring the stability of the movable base 1. Then, the fan impeller is placed outside the positioning block 17. Next, the lifting motor 15 is started using the controller to lift the impeller. The lowering motor 15 drives the lifting threaded rod 14 to rotate between the inner walls of the lifting groove 13, and drives the lifting block 21 to move the movable plate 16 to one side of the column 12, thereby aligning the fan impeller with the external fan. Then, the displacement motor 4 drives the displacement threaded rod 3 to rotate between the inner walls of the displacement groove 2, thereby driving the displacement block 20 to move the column 12 to the top of the movable base 1, thereby moving the fan impeller closer to the external fan. At the same time, the two telescopic electric cylinders 18 will push the two push plates 19 to move outside the positioning block 17, thereby pushing the fan impeller into the interior of the external fan. Then, the fan impeller is fixed with external bolts, thus completing the installation of the fan impeller.

[0027] When the fan impeller is removed, the external bolts are first removed to release the fan impeller from its fixation. Then, the fan impeller is supported by the positioning block 17. Finally, the displacement motor 4 drives the displacement threaded rod 3 to rotate between the inner walls of the displacement groove 2, thereby driving the displacement block 20 to move the column 12 on the top of the moving base 1 again, and moving the fan impeller out of the interior of the external fan, thus completing the removal of the fan impeller. This completes the quick removal and installation of the fan impeller by the disassembly and assembly device.
