[0002] A published Chinese patent (CN208046407U) discloses a disassembly device for a large traction motor rotor, comprising a base plate, a fixed frame, a slide groove, a pressing hydraulic cylinder, a fixed plate, a horizontal pushing hydraulic cylinder, an arc-shaped block, a fixed sleeve, a slide rail, a horizontal plate, a fixed column, a bracket, a fixed hydraulic cylinder, a motor, and a rotor. The device is characterized by a fixed frame and a slide groove on the base plate; the pressing hydraulic cylinder is located on the lower surface of the fixed frame's horizontal bar; a fixed plate is located at the free end of the horizontal pushing hydraulic cylinder; the horizontal pushing hydraulic cylinder is located on the lower surface of the fixed plate; an arc-shaped block is located at the free end of the horizontal pushing hydraulic cylinder; and a slide rail is located on the lower surface of the horizontal plate, within the slide groove. After the device is completed, the rotor can be removed without damage using different models of traction motors via the fixed column, allowing for internal maintenance, cleaning, and inspection of the motor. While this device can remove rotors from different motor models, it requires clamping and fixing one end of the rotor before horizontally separating it from the motor casing. During removal, the rotor's center of gravity shifts, causing the unclamped end to tilt, increasing the probability of secondary damage to the rotor. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 As shown, the large motor rotor disassembly device includes a base 1 and a bracket 2 mounted on the base 1, and also includes:

[0037] Positioning ring 3 is set on base 1;

[0038] Square grooves 4 are evenly distributed around the circumference of positioning ring 3;

[0039] The top plate assembly is located at square groove 4;

[0040] Telescopic element 5 is installed on the top surface of bracket 2;

[0041] U-shaped plate 6 is used to connect to the output end of telescopic element 5;

[0042] Motor 7 is mounted on U-shaped plate 6;

[0043] Connecting rod 8 is used to connect to the output shaft of motor 7. Connecting shaft 9 is provided at both ends of connecting rod 8.

[0044] The second connecting rod 10 is connected to the first connecting shaft 9 at one end and has a second connecting shaft 11 at the other end;

[0045] Square plate 12 is disposed at the bottom of U-shaped plate 6, and the square plate 12 is provided with a sliding groove 13;

[0046] Slider 14 is used to connect with the second connecting shaft 11 and to cooperate with the slide groove 13;

[0047] The clamping plate 15 is located at the bottom of the slider 14.

[0048] The telescopic element 5 is a hydraulic cylinder, and a controller is installed on the bracket 2. During operation, the motor to be disassembled is vertically placed into the positioning ring 3. The top plate assembly passes through the square groove to fix the motor to be disassembled. The first motor 7 drives the first connecting rod 8 to rotate, which in turn drives the second connecting rod 10 to move. Then, the second connecting rod 10 drives the slider 14 to slide in the slide groove 13. At the same time, the slider 14 will move the clamping plate 15 to clamp the rotor. Then, the piston rod of the hydraulic cylinder is activated to retract, which drives the clamping plate 15 to move upward. This can effectively pull the rotor vertically out of the motor, keep the rotor's center of gravity vertical, avoid tilting due to the center of gravity shifting during the rotor's extraction, and reduce the probability of secondary damage to the rotor.

[0049] In the embodiments, such as Figure 3 , Figure 5 As shown, the inner wall of the slide groove 13 has grooves 16 on both sides, and the slider 14 has protrusions 17 on both sides for engaging with the grooves 16. This ensures the linearity and stability of the slider 14's movement within the slide groove 13.

[0050] In the embodiments, such as Figure 7 , Figure 8 , Figure 9 As shown, the top plate assembly includes a fixing base 18 and a top plate 19. The fixing base 18 is provided with a threaded rod 20 for connecting with the top plate 19, and the threaded rod 20 cooperates with the fixing base 18. The top plate assembly has at least three sets. By rotating the threaded rod 20, the top plate 19 is moved back and forth, thereby achieving the clamping or loosening of the motor housing to be disassembled, which is convenient to operate.

[0051] In the embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the fixed base 18 is provided with a threaded sleeve 21 for engaging with the threaded rod 20. The threaded sleeve 21 is rotatably mounted on the fixed base 18. The base 1 is provided with a power device 22, and a transmission assembly is provided between the threaded sleeve 21 and the power device 22. The power device 22 realizes the rotation of the threaded sleeve 21 through the transmission assembly, thereby enabling the threaded rod 20 to move automatically back and forth without manual operation.

[0052] In the embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the power unit 22 is a second motor. The transmission assembly includes a first gear 23 mounted on the second motor, a second gear 24 mounted on the threaded sleeve 21, a fixed ring 25, a gear ring 26, and a crown gear 27 mounted on the base 1. The crown gear 27 is rotatably mounted on the fixed ring 26. The gear ring 26 is connected to the crown gear 27. The gear ring 26 meshes with the first gear 23, and the crown gear 27 meshes with the second gear 24. The second motor drives the first gear 23 to rotate, which in turn drives the gear ring 26 to rotate. The gear ring 26 then drives the crown gear 27 to rotate, which in turn drives the second gear 24 to rotate. Simultaneously, the second gear 24 drives the threaded sleeve 21 to rotate. When the threaded sleeve 21 rotates, it causes the threaded rod 20 to move, thus achieving automatic back-and-forth movement of the threaded rod 20.

[0053] In the embodiments, such as Figure 7 , Figure 8 , Figure 9 As shown, a guide rod 28 is installed on the top plate 19 for cooperating with the fixed seat 18. The guide rod 28 is used to ensure the straightness of the top plate 19 during movement.

[0054] In the embodiments, such as Figure 7 , Figure 8 As shown, the clamping surface of the top plate 19 is provided with an elastic anti-slip layer 29. The elastic anti-slip layer 29 is used to contact the motor housing to be disassembled, preventing the motor housing from moving during the disassembly process, and at the same time preventing the top plate 19 from damaging the surface of the motor housing.

[0055] Detailed Implementation: When the operator needs to use the equipment, first, the motor to be disassembled is vertically placed into the positioning ring 3. After the motor is placed, the operator starts the second motor through the controller. After the second motor starts, it will drive the first gear 23 to rotate. The first gear 23 will drive the gear ring 26 to rotate. When the gear ring 26 rotates, it will drive the crown gear 27 to rotate. When the crown gear 27 rotates, it will drive the second gear 24 to rotate. At the same time, the second gear 24 will drive the threaded sleeve 21 to rotate. When the threaded sleeve 21 rotates, it will cause the threaded rod 20 to move. When the threaded rod 20 moves, it will drive the top plate 19 to move. During the movement of the top plate 19, the guide rod 28 ensures the straightness of the movement of the top plate 19. Then the top plate 19 will pass through the square groove 4 and fix the motor to be disassembled, avoiding displacement and shaking during subsequent rotor disassembly, making the disassembly process more stable. After the motor is fixed, the operator starts the extension through the controller. The telescopic element 5 moves up and down along with the U-shaped plate 6 and the square plate 12. When the clamping plate 15 moves to both sides of the rotor, the operator starts the first motor 7 through the controller. After the first motor 7 starts, it will rotate the first connecting rod 8. The second connecting rod 10 moves through the first connecting shaft 9. Then the second connecting rod 10 moves the second connecting shaft 11. When the second connecting shaft 11 moves, it will slide the slider 14 in the slide groove 13. At the same time, the slider 14 will move the clamping plate 15. When the clamping plate 15 moves relative to the rotor, it will clamp the rotor. After the rotor is clamped, the operator uses the controller to retract the telescopic element 5. When the telescopic element 5 retracts, it will move the clamping plate 15 upward through the cooperation of multiple parts. When the clamping plate 15 moves, it will move the rotor vertically, so that the rotor can be removed from the motor, avoiding swaying due to unstable center of gravity and reducing the probability of secondary rotor damage.

[0056] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
