Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a device for quickly disassembling the motor backrest wheel. Background Technology

[0002] Traditional manual disassembly of the motor backrest wheel requires tools such as a lead screw, jack, jacking block, and fixing nut. During operation, the lead screw is passed through the pin hole of the backrest wheel and locked in place by the nut. Then, the jack simultaneously presses against the motor rotor and pulls the lead screw, which, relying on the pulling force and the nut's locking mechanism, removes the backrest wheel. However, this method has the following drawbacks:

[0003] 1. The height of the backrest wheels is different, and the existing device is not convenient for adjusting the height of the disassembly tools.

[0004] 2. When disassembling, the axis of the telescopic end of the jack must be parallel to the axis of the rotor so that the backrest wheel can be pulled out axially. If the two axes are not parallel, the backrest wheel will be subjected to a biased force angle, making it easy to jam when pulling out the backrest wheel, or even causing wear.

[0005] 3. During the application of force, the device is prone to displacement, which causes the backrest wheel to be unable to bear force in a stable direction, resulting in low efficiency and difficulty in pulling out the backrest wheel. Summary of the Invention

[0006] This invention discloses a device for quickly disassembling the motor backrest wheel, with the aim of solving the problems described in sections 1-3 of the background art.

[0007] To achieve the above objectives, the technical solution of this invention is as follows:

[0008] A device for quickly disassembling motor backrest wheels includes a base, a counterweight, a fixing plate, a linear lifting mechanism, a disassembly mechanism, a robotic arm, and a pressure foot. The base has a universal wheel with a brake at its bottom end, a counterweight at its top end, a fixing plate at its front end, a linear lifting mechanism on the fixing plate, and a disassembly mechanism connected to the linear lifting mechanism. The left and right sides of the counterweight are respectively connected to robotic arms, and the ends of the robotic arms are connected to pressure feet for pressing against the ground.

[0009] Preferably, the fixing plate is fixedly disposed longitudinally at the front end of the base, the rear end of the fixing plate is fixedly connected to the counterweight, and a rectangular groove is formed longitudinally in the middle of the fixing plate. The linear lifting mechanism includes a lead screw disposed longitudinally in the rectangular groove. The two ends of the lead screw are rotatably connected to the top and bottom of the rectangular groove, respectively. The top end of the lead screw passes through the top of the fixing plate and is fixedly connected to a disc handle. A movable seat is slidably connected in the rectangular groove. The outer end of the movable seat is connected to the disassembly mechanism, and the movable seat is screwed to the lead screw.

[0010] Preferably, the robotic arm includes an electrically controlled telescopic mechanism, the fixed end of which is fixedly connected to the side wall of the counterweight, and the telescopic end is hinged with a pressure foot.

[0011] Preferably, the counterweight has a cubic structure, and the electrically controlled telescopic mechanism is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0012] Preferably, the telescopic end is coaxially fixedly connected to a connecting rod, the end of the connecting rod is hinged to the presser foot, and a spring is connected between the upper end of the inner surface of the presser foot and the inner end of the outer wall of the connecting rod.

[0013] Preferably, the disassembly mechanism includes a mounting plate fixedly connected to the front end of the movable seat. A hydraulic cylinder is mounted in the middle of the mounting plate in a direction perpendicular to the mounting plate. The fixed end of the hydraulic cylinder is fixedly connected to the mounting plate, and the telescopic end is connected to a rubber anti-slip pad. Four telescopic rods are arranged in a rectangle around the outer periphery of the hydraulic cylinder. The ends of the four telescopic rods are fixedly connected to a positioning ring. Two lead screws are symmetrically arranged on the outer surface of the mounting plate outside the four telescopic rods about the axis of the hydraulic cylinder. The ends of the lead screws are provided with threaded sections, and the threaded sections are equipped with limit nuts.

[0014] Preferably, the positioning ring is a rectangular ring structure, and the front and rear surfaces of the positioning ring are parallel to the outer surface of the mounting plate.

[0015] Preferably, a tension bearing is coaxially fixedly connected to the front end of the mounting plate, and a fixing ring is connected to the mounting plate through the tension bearing. The lead screw is symmetrically arranged on the outer surface of the fixing ring.

[0016] Preferably, the rear end of the base is also provided with a handrail.

[0017] The advantages of this novel device for quickly disassembling motor backrest wheels are as follows:

[0018] This new type of device allows for easy adjustment of the disassembly mechanism's height. By setting a positioning ring, the hydraulic cylinder can be ensured to apply force along the axial direction of the backrest wheel. By setting a counterweight, a robotic arm, a pressure foot, and universal wheels with brakes, the stability of the device during use can be ensured. By connecting the fixing ring with a tension bearing, the ease of screw alignment can be improved. With the above settings, the difficulty of disassembling the backrest wheel can be greatly reduced, and the disassembly efficiency can be improved. Attached Figure Description

Detailed Implementation

[0022] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0023] In this embodiment, a device for quickly disassembling the motor backrest wheel is provided, such as... Figure 1 , 2 As shown, the device includes a base 1, a counterweight 18, a fixing plate 3, a linear lifting mechanism, a disassembly mechanism, a robotic arm 15, and pressure feet 16. The base 1 has casters 2 with brakes at its bottom, a counterweight 18 at its top, and a fixing plate 3 at its front. A linear lifting mechanism is mounted on the fixing plate 3, and this mechanism is connected to the disassembly mechanism. Robotic arms 15 are connected to the left and right sides of the counterweight 18, and pressure feet 16 are connected to the ends of the robotic arms 15 for pressing against the ground. The linear lifting mechanism raises and lowers the disassembly mechanism to a suitable height for assembly and disassembly. Once the working position is reached, the casters are locked, and then the robotic arm is activated to press the two pressure feet against the ground on both sides, achieving relative fixation of the device to the ground and preventing displacement during disassembly. The counterweight increases the weight of the device, further improving its stability during use.

[0024] In this embodiment, as Figure 1 , 2 As shown, the fixing plate 3 is fixedly mounted longitudinally at the front end of the base 1, and the rear end of the fixing plate 3 is fixedly connected to the counterweight 18. A rectangular groove 4 is longitudinally formed in the middle of the fixing plate 3. The linear lifting mechanism includes a lead screw 5 longitudinally mounted in the rectangular groove. The two ends of the lead screw 5 are rotatably connected to the top and bottom of the rectangular groove 4, respectively. The top end of the lead screw 5 passes through the top of the fixing plate 3 and is fixedly connected to a disc handle 6. A movable seat 10 is slidably connected in the rectangular groove 4. The outer end of the movable seat 10 is connected to the disassembly mechanism, and the movable seat 10 is screwed to the lead screw 5. Rotating the disc handle causes the lead screw to rotate, thereby driving the movable seat to move up and down along the rectangular groove, and the movable seat in turn drives the disassembly mechanism to move up and down.

[0025] In this embodiment, as Figure 1 , 2As shown, the robotic arm 15 includes an electrically controlled telescopic mechanism. The fixed end of the electrically controlled telescopic mechanism is fixedly connected to the side wall of the counterweight block 18, and the telescopic end is hinged with a pressure foot 16.

[0026] In this embodiment, as Figure 1 , 2 As shown, the counterweight 18 has a cubic structure, and the electrically controlled telescopic mechanism is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0027] In this embodiment, as Figure 1 , 2 As shown, the telescopic end is coaxially fixedly connected to a connecting rod (such as...). Figure 1 As shown in the figure (not marked), the end of the connecting rod is hinged to the pressure foot 16. A spring 17 is connected between the upper end of the inner surface of the pressure foot 16 and the inner end of the outer wall of the connecting rod. The spring is used to maintain a certain angle between the pressure foot and the connecting rod, so as to adapt to the change of angle between the connecting rod and the ground when in contact with the ground. After the two sides of the device are fixed to the ground by the pressure feet, the stability of the device can be fully guaranteed during disassembly with the cooperation of the counterweight and the locked universal wheels, and the force direction of the backrest wheels can be continuously changed.

[0028] In this embodiment, as Figure 1 , 2 As shown, the disassembly mechanism includes a mounting plate 7 fixedly connected to the front end of the movable seat 10. A hydraulic cylinder 13 is mounted in the middle of the mounting plate 7 in a direction perpendicular to the mounting plate. The fixed end of the hydraulic cylinder 13 is fixedly connected to the mounting plate 7, and the telescopic end is connected to a rubber anti-slip pad (for anti-slip when pressed against the output shaft of the rotor or motor). Four telescopic rods 14 are arranged in a rectangle around the outer periphery of the hydraulic cylinder 13. The ends of the four telescopic rods 14 are fixedly connected to a positioning ring 12. Two lead screws 9 are symmetrically arranged on the outer surface of the mounting plate 7, which is located outside the four telescopic rods 14, about the axis of the hydraulic cylinder. The ends of the lead screws 9 are provided with threaded sections, and the threaded sections are equipped with limit nuts 11.

[0029] In this embodiment, as Figure 1 , 2 As shown, the positioning ring 12 is a rectangular ring structure, and the front and rear surfaces of the positioning ring are parallel to the outer surface of the mounting plate.

[0030] In this embodiment, as Figure 1 , 2 As shown, a tension bearing 19 is coaxially fixedly connected to the front end of the mounting plate 7, and a fixing ring 8 is connected to the mounting plate 7 through the tension bearing 19. The lead screw 5 is symmetrically arranged on the outer surface of the fixing ring 8, and a handrail 20 is also provided at the rear end of the base 1.

[0031] How to use this new invention:

[0032] Move the device to the disassembly position, rotate the disc handle to raise the disassembly mechanism to the required height, and pull out the positioning ring 12. The four telescopic rods extend synchronously by the same length, so that all four sides of the outer surface of the positioning ring are in contact with the surface of the backrest wheel. At this time, the axis of the hydraulic cylinder is parallel to the axis of the backrest wheel. While maintaining the contact between the positioning ring and the backrest wheel, rotate the fixing ring and move the device forward. Pass the two lead screws through the two symmetrical pin holes of the backrest wheel and lock them in place with the limit nuts. Since all four sides of the positioning ring are in contact with the surface of the backrest wheel, the two limit nuts are locked in the same position relative to the lead screws. Due to the limit between the two lead screws and the pin holes, the telescopic end of the hydraulic cylinder is now directly opposite the rotor or output shaft of the motor. Start the hydraulic cylinder to make the rubber anti-slip pad contact the end of the rotor or output shaft. Start the robotic arm 15 to fix the pressure foot to the ground and lock the caster wheel to make the device reach the most stable state. Continue to start the hydraulic cylinder to pull the backrest wheel out axially through the lead screw.
