Description

Technical Field

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

[0002] The impeller is a key rotating component in a fan. It is typically a rigid, shaft-mounted assembly consisting of multiple blades arranged at specific angles and shapes on a hub or disc, enclosed within a casing or volute to form specific flow channels, as shown in the instruction manual. Figure 4-5 As shown, a fan impeller includes an impeller body, a fan shaft, a shaft disc, and a fixed disc. One side of the impeller body is fixedly connected to one side of the shaft disc, one end of the fan shaft is fixedly connected to one end of the fixed disc, and the other end of the fan shaft is rotatably connected to the inner wall of a through hole opened on the surface of the shaft disc.

[0003] Existing wind turbine impeller disassembly devices often use ordinary pullers. When disassembling the impeller, the connection stability between the puller and the wind turbine shaft is poor, and slippage and misalignment are prone to occur. This not only reduces disassembly efficiency but may also damage the impeller or shaft. Furthermore, some disassembly devices connect bolts to the wind turbine shaft and then push it with a hydraulic puller. Due to the lack of an effective limiting and stabilizing structure for the bolts, the bolts are prone to displacement under the thrust of the hydraulic puller, resulting in uneven force during disassembly, affecting the disassembly effect, and even causing safety hazards.

[0004] Therefore, it is necessary to provide a new wind turbine impeller disassembly device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fan impeller disassembly device.

[0006] The present invention provides a fan impeller disassembly device comprising: a fixed plate, a guide rod, a transmission assembly, a pushing assembly, and two limiting assemblies. The fixed plate has a partition inside and a sliding groove on its surface. One end of the guide rod is fixedly connected to one side of the partition, and the other end of the guide rod is fixedly connected to the inner wall of the fixed plate. One end of the transmission assembly is fixedly connected to one side of the partition, and the surface of the transmission assembly is rotatably connected to the inner wall of the through hole on one side of the two limiting assemblies. One end of the pushing assembly is fixedly connected to one side of the fixed plate. Preferably, the limiting component includes a sliding block, a gear ring, a connecting ring, a driving mechanism, and multiple driven mechanisms. The inner wall of the through hole on the surface of the sliding block is threadedly connected to the surface of the lead screw. The inner wall of the through hole on the surface of the sliding block is slidably connected to the surface of the guide rod. The surface of the gear ring is rotatably connected to the inner wall of the sliding block. Both ends of the connecting ring are fixedly connected to both sides of the inner wall of the sliding block. The surfaces of the multiple driven mechanisms are slidably connected to the inner walls of the multiple through slots on the surface of the connecting ring. One end of the driving mechanism is rotatably connected to the inner wall of the sliding block.

[0007] Preferably, the driven mechanism includes a rack and a gear 1. The surface of the rack is slidably connected to the inner wall of a through groove on the surface of the connecting ring. One side of the rack meshes with the surface of the gear 1. One side of the gear 1 is rotatably connected to the inner wall of the sliding block. The surface of the gear 1 meshes with the inner side of the gear ring.

[0008] Preferably, the driving mechanism includes a second gear and a second motor. One side of the second gear is rotatably connected to the inner wall of the sliding block, and the other side of the second gear is fixedly connected to the output end of the second motor. One end of the second motor is fixedly connected to the inner wall of the sliding block.

[0009] Preferably, the transmission assembly includes a motor and a lead screw. One end of the motor is fixedly connected to one side of the partition, the output end of the motor is fixedly connected to one end of the lead screw, and the other end of the lead screw is rotatably connected to the inner wall of the fixed plate.

[0010] Preferably, the pushing assembly includes a fixed cylinder, a hydraulic cylinder, and a hydraulic oil pipe. One end of the fixed cylinder is fixedly connected to one side of a fixed plate. The outer surface of the hydraulic cylinder is threaded and is threadedly connected to the inner wall of the fixed cylinder. The end of the hydraulic cylinder away from the fixed cylinder is fixedly connected to one end of the hydraulic oil pipe.

[0011] Preferably, the rack has a threaded ring on its inner side that abuts against the bolt surface.

[0012] Compared with related technologies, the fan impeller disassembly device provided by this utility model has the following advantages: When disassembling the impeller, one side of the fixing plate is attached to one end of the shaft disk. The motor drives the lead screw to rotate, aligning the center of the two sliding blocks with the two threaded holes on the surface of the shaft disk. This facilitates the insertion of screws to connect with the shaft disk, improving the positioning accuracy and operational stability of the device. The guide rod limits the movement of the two sliding blocks, ensuring that the sliding blocks move smoothly along a straight line under the drive of the lead screw.

[0013] Motor 2 drives gear 2 to rotate, which in turn drives multiple gears 1 to rotate. Simultaneously, multiple racks slide along the inner wall of the groove on the surface of the connecting ring, limiting and fixing the bolts that are threaded into the threaded holes. This ensures that the limiting and fixing operations of multiple racks on the bolts are highly consistent, ensuring that the bolts are subjected to uniform force in the circumferential direction. This prevents the bolts from loosening or being damaged due to uneven force. At the same time, when the threaded surface of the rack abuts against the surface of the bolt, it enhances the limiting and fixing effect on the bolts, avoids vibration or external force interference, and effectively prevents the bolts from rotating or displacing.

[0018] In the specific implementation process, such as Figure 1-5 As shown, it includes: a fixed plate 3, a guide rod 304, a transmission assembly, a pushing assembly, and two limiting assemblies. The fixed plate 3 has a partition 301 inside and a sliding groove on its surface. One end of the guide rod 304 is fixedly connected to one side of the partition 301, and the other end of the guide rod 304 is fixedly connected to the inner wall of the fixed plate 3. One end of the transmission assembly is fixedly connected to one side of the partition 301, and the surface of the transmission assembly is rotatably connected to the inner wall of the through hole opened on one side of the two limiting assemblies. One end of the pushing assembly is fixedly connected to one side of the fixed plate 3. The limiting assembly includes a sliding block 5, a gear ring 501, a connecting ring 502, a driving mechanism, and multiple driven mechanisms. The inner wall of the through hole on the surface of the sliding block 5 is threadedly connected to the surface of the lead screw 303. The inner wall of the through hole on the surface of the sliding block 5 is slidably connected to the surface of the guide rod 304. The surface of the gear ring 501 is rotatably connected to the inner wall of the sliding block 5. Both ends of the connecting ring 502 are fixedly connected to both sides of the inner wall of the sliding block 5. The surfaces of multiple driven mechanisms are slidably connected to the inner walls of multiple through slots on the surface of the connecting ring 502. One end of the driving mechanism is rotatably connected to the inner wall of the sliding block 5. The driven mechanism includes a rack 503 and a gear 504. The surface of the rack 503 is slidably connected to the inner wall of the through groove opened on the surface of the connecting ring 502. One side of the rack 503 meshes with the surface of the gear 504. One side of the gear 504 is rotatably connected to the inner wall of the sliding block 5. The surface of the gear 504 meshes with the inner side of the gear ring 501. The inner side of the rack 503 is provided with a threaded ring that abuts against the surface of the bolt. The drive mechanism includes a second gear 505 and a second motor 506. One side of the second gear 505 is rotatably connected to the inner wall of the sliding block 5, and the other side of the second gear 505 is fixedly connected to the output end of the second motor 506. One end of the second motor 506 is fixedly connected to the inner wall of the sliding block 5. The second motor 506 drives the second gear 505 to rotate, which causes the gear ring 501 to drive multiple gears 504 to rotate. Simultaneously, multiple racks 503 slide along the inner wall of the through groove on the surface of the connecting ring 502, limiting and fixing the bolts that are threaded to the threaded hole 103. This ensures that the limiting and fixing operation of the multiple racks 503 on the bolts is highly consistent, ensuring that the bolts are evenly stressed in the circumferential direction and avoiding bolt loosening or damage due to uneven stress. The transmission assembly includes a motor 302 and a lead screw 303. One end of the motor 302 is fixedly connected to one side of the partition 301, and the output end of the motor 302 is fixedly connected to one end of the lead screw 303. The other end of the lead screw 303 is rotatably connected to the inner wall of the fixed plate 3. When the impeller body 1 is disassembled, one side of the fixed plate 3 is attached to one end of the shaft disk 104. The motor 302 drives the lead screw 303 to rotate, so that the center of the two sliding blocks 5 is aligned with the two threaded holes 103 on the surface of the shaft disk 104, which improves the positioning accuracy and operational stability of the device. The guide rod 304 limits the two sliding blocks 5 to ensure that the sliding blocks 5 move smoothly along a straight line under the drive of the lead screw 303. The pushing assembly includes a fixed cylinder 4, a hydraulic cylinder 401, and a hydraulic oil pipe 402. One end of the fixed cylinder 4 is fixedly connected to one side of the fixed plate 3. The outer surface of the hydraulic cylinder 401 is threaded and is threaded to the inner wall of the fixed cylinder 4. The end of the hydraulic cylinder 401 away from the fixed cylinder 4 is fixedly connected to one end of the hydraulic oil pipe 402. The hydraulic oil pipe 402 is connected to the output end of the manual hydraulic pump. When the fixed plate 3 is fixed to the shaft disk 104, the manual hydraulic pump pushes out the abutment rod inside the hydraulic cylinder 401, forcing and squeezing the surface of the fan shaft 102, so that the fan shaft 102 and the fixed disk are pushed out of the inner wall of the shaft disk 104, thus completing the disassembly of the impeller body 1. The impeller body 1, the fan shaft 102, the shaft disk 104 and the fixed disk 2 are fixedly connected to one side of the impeller body 1 and one side of the shaft disk 104. One end of the fan shaft 102 is fixedly connected to one end of the fixed disk 2. The other end of the fan shaft 102 is rotatably connected to the inner wall of the through hole opened on the surface of the shaft disk 104. The fixed plate 3 is threadedly connected to the inner wall of the two threaded holes 103 opened on one side of the shaft disk 104 by two bolts.

[0019] The working principle provided by this utility model is as follows: When disassembling the impeller body 1, one side of the fixing plate 3 is attached to one end of the shaft disk 104. The motor 302 drives the lead screw 303 to rotate, aligning the center of the two sliding blocks 5 with the two threaded holes 103 on the surface of the shaft disk 104. This improves the positioning accuracy and operational stability of the device. The guide rod 304 limits the movement of the two sliding blocks 5, ensuring that the sliding blocks 5 move smoothly in a straight line under the drive of the lead screw 303. The motor 506 drives the gear 505 to rotate, causing the gear ring 501 to drive multiple gears 5. 04 rotates, simultaneously driving multiple racks 503 to slide along the inner wall of the through groove on the surface of the connecting ring 502, limiting and fixing the bolts threaded to the threaded hole 103. This ensures that the limiting and fixing operation of the multiple racks 503 on the bolts is highly consistent, ensuring that the bolts are subjected to uniform force in the circumferential direction, and avoiding bolt loosening or damage due to uneven force. At the same time, when the threaded surface of the rack 503 abuts against the bolt surface, it can enhance the limiting and fixing effect on the bolts, avoid vibration or external force interference, and effectively prevent the bolts from rotating or displacing.
