Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-11 As shown, a wheel disassembly and assembly machine includes a rectangular frame 1, with a support leg 5 fixed at the bottom of the rectangular frame 1; the two ends of the rectangular frame 1 are the head end and the tail end, respectively, and a fixed frame 2, a limiting frame 3, and a movable frame 4 are arranged sequentially from the head end to the tail end inside the rectangular frame 1. Both the fixed frame 2 and the limiting frame 3 are fixed to the inner wall of the rectangular frame 1. A hydraulic cylinder 6 with a stroke facing the limiting frame 3 is fixed through the fixed frame 2. A sleeve 7 is fixed to the telescopic end of the hydraulic cylinder 6. A disassembly and assembly tool 8 for disassembling and assembling the wheel axle 24 and bearing 25 is movably inserted into the sleeve 7. The telescopic end of the hydraulic cylinder 6 drives the sleeve 7 and the disassembly and assembly tool 8 to telescopically move towards the limiting frame 3. The fixing frame 2 includes a vertical housing 2.1, through which a cylinder 2.2 for fixing a hydraulic cylinder 6 is inserted and fixed, and multiple stiffening plates 2.3 are fixed between the cylinder 2.2 and the inner wall of the housing 2.1.

[0029] The disassembly and assembly tool 8 is a straight round rod 8.1 with a diameter less than or equal to the diameter of the wheel axle 24, or a variable diameter round rod 8.2 with a T-shaped cross-section. The diameter of the thick end of the variable diameter round rod 8.2 is less than or equal to the outer ring diameter of the bearing 25. The straight round rod 8.1 is inserted into the sleeve 7. As the hydraulic cylinder 6 extends, the wheel axle 24 can be pushed out of the bearing 25. After replacing the variable diameter round rod 8.2, the narrow end is inserted into the sleeve 7, and the thick end can be pushed out of the wheel 23 as the hydraulic cylinder 6 extends.

[0030] The top of the limiting frame 3 has a notch 9, and a support plate 10 is fixedly inserted through the limiting frame 3 below the notch 9. The top of the support plate 10 is recessed in the middle. The limiting frame 3 is used to axially limit the wheel 23. The notch 9 is used to provide space for the wheel axle 24. One wheel 23 is placed on the support plate 10 facing the first end of the rectangular frame 1, and another wheel 23 is placed on the top of the support plate 10 facing the last end of the rectangular frame 1. The recessed part at the top of the support plate 10 is set along the axial direction of the wheel axle 24 and protrudes on both sides. Its purpose is to allow the bottom of the wheel 23 to be matched, adapted, and placed stably. A shaft 11 is fixed on the limiting frame 3 facing the first end of the rectangular frame 1. A limiting rod 12 is rotatably connected to the shaft 11. The limiting rod 12 can rotate to rest on one side of the wheel rim of the wheel 23, axially limiting the wheel 23, so that the wheel 23 is limited to one side of the limiting frame 3. Remove the wheel axle 2. 4. To prevent axial movement of wheel 23 when installing bearing 25, wheel 23 needs to move when it is installed on axle 24 and when it needs to be placed in reverse after removing bearing 25. Therefore, the limit rod 12 is rotated to move the wheel 23 without axial limitation. A bearing support 13 for supporting bearing 25 is fixed on the side of support plate 10 facing the first end of rectangular frame 1. When installing bearing 25, bearing 25 can be lifted to the bearing hole side of wheel 23 by bearing support 13, which is convenient for hydraulic cylinder 6 to push bearing 25 into bearing hole of wheel 23. A support block 14 is fixed on the top of support plate 10 facing the tail end of rectangular frame 1. A wheel axle limit block 15 is fixed on the top of support block 14. The top of wheel axle limit block 15 matches wheel axle 24 in an arc shape. The height of support block 14 can reach below wheel axle 24. Wheel axle limit block 15 supports wheel axle 24. The limiting frame 3 includes two vertical plates 3.1, the top of the two vertical plates 3.1 is provided with a notch 9, and a plurality of short plates 3.2 are fixed between the two vertical plates 3.1; The bearing support 13 includes a vertical rod 13.1, with a diagonal rod 13.2 rotatably connected to the top of the vertical rod 13.1 toward the support plate 10. The top of the diagonal rod 13.2 is provided with a groove 13.3. A rotating shaft 13.4 is fixed to the groove wall of the groove 13.3. A rotating block 13.5 is rotatably sleeved on the rotating shaft 13.4 toward the recess 9. An arc-shaped plate 13.6 is fixedly connected to the top of the rotating block 13.5. The bottom of the rotating block 13.5 toward the recess 9 is in movable contact with the bottom of the groove 13.3. The bottom of the rotating block 13.5 opposite to the recess 9 is arc-shaped. Without using the bearing support 13, the arc-shaped plate 13.6 is moved to the inner wall of the rectangular frame 1, away from the wheel 23 placed on the side of the recess 9 of the limiting frame 3, by the rotation of the diagonal rod 13.2 on the vertical rod 13.1; when using the bearing support 13, the diagonal rod 13.2 rotates on the vertical rod 13.1 to move the arc-shaped plate 13.6 to the wheel 23 on the side of the recess 9 of the limiting frame 3. Now, the end of the arc-shaped plate 13.6 facing the recess 9 is lifted, and the rotating block 13.5 rotates on the rotating shaft 13.4. Now, the end of the arc plate 13.6 is offset from the side of the wheel 23, and then the diagonal bar 13.2 is pressed against the top of the side of the support plate 10 facing the head of the rectangular frame 1 for limiting. Finally, the arc plate 13.6 is laid flat downwards and the rotation is limited by the bottom of the rotating block 13.5 pressing against the bottom of the groove 13.3. At this time, the arc plate 13.6 is aligned with the bearing hole of the wheel 23 and is close to it. The bearing 25 is placed on the arc plate 13.6 and the bearing support 13 can lift the bearing 25 to the side of the bearing hole of the wheel 23.

[0031] U-shaped grooves 16 are fixed on the inner wall of the rectangular frame 1 at both ends of the movable frame 4. The two ends of the movable frame 4 are slidably inserted into the corresponding U-shaped grooves 16. A circular top plate 17 is fixed on the side of the movable frame 4 facing the head of the rectangular frame 1. A positioning support rod 18 is fixed on the side of the movable frame 4 facing the tail of the rectangular frame 1. The end of the positioning support rod 18 is movably resting in the half sleeve 19 fixed to the tail of the rectangular frame 1.

[0032] The movable frame 4 can be installed in the rectangular frame 1 or removed from the rectangular frame 1 by being inserted and removed in the U-shaped groove 16. The end of the positioning support rod 18 is movably placed in the half sleeve 19, the half sleeve 19 supports the positioning support rod 18, and the positioning support rod 18 can also abut against the tail end of the rectangular frame 1 to give a reverse force. When the movable frame 4 is installed, the movable frame 4 abuts against one wheel 23 through the circular top plate 17, limiting the axial movement of the wheel axle 24, so that the other wheel 23 can be pushed and installed on the wheel axle 24. Disassembling the axle 24 requires moving the axle 24, while disassembling and installing the bearing 25 can be done on the wheel 23. Therefore, there is no need to limit the axle 24, and the movable frame 4 can be removed to reduce interference.

[0033] Support blocks 20 are placed between the tail end of the rectangular frame 1 and the two included angles of the inner walls on both sides of the rectangular frame 1. After the movable frame 4 is removed from the rectangular frame 1, it can be placed on the two support blocks 20. The positioning support rod 18 is placed on the tail end of the rectangular frame 1 to temporarily place the movable frame 4. The use of hydraulic cylinder 6 does not affect the placement of the movable frame 4.

[0034] A T-shaped wheel axle bracket 21 is fixed to the top of the tail end of the rectangular frame 1. A groove block 22 matching the curvature of the wheel axle 24 is fixed to the top of the wheel axle bracket 21. Usually, the car has a pair of wheel sets. When one wheel set is being repaired, the other can be placed on the top of the wheel axle bracket 21. The groove block 22 can limit the wheel axle 24 and place it securely.

[0035] Working principle: In this embodiment, the trolley has a pair of wheel sets, which include two wheels 23, an axle 24, and a bearing 25 between the wheel 23 and the axle 24. Each wheel 23 has two bearings 25. The movement of the wheel set is accomplished by using a grabber from an electric hoist or overhead crane. like Figure 1 , 2 As shown, the process of disassembling the wheel axle 24 of this utility model is as follows: the wheel axle 24 of a wheel set is placed in the wheel axle limiting block 15 on the support block 14, and the two wheels 23 are placed on the support plates 10 on both sides of the limiting frame 3. One wheel 23 crosses the notch 9 and its wheel rim abuts against the side of the limiting frame 3. The limiting rod 12 rotates and blocks the wheel rim of this wheel 23, restricting the axial movement of the wheel 23. At this time, the bearing support 13 moves to the side away from the wheel 23, and the movable frame 4 is no longer installed in the rectangular frame 1. Then, the hydraulic cylinder 6 drives the sleeve 7 to extend the disassembly tool 8, which is a straight round rod 8.1. The straight round rod 8.1 pushes the wheel axle 24 off the bearing 25 of this wheel 23 and removes it. The wheel set is then flipped in the same direction, and the wheel axle 24 is pushed off the bearing 25 of the other wheel 23 and removed.

[0036] like Figure 3 , 4 As shown, the installation state of the wheel axle 24 of this utility model is as follows: the wheel axle 24 of a wheel set is placed in the wheel axle limiting block 15 on the support block 14, the movable frame 4 is installed in the rectangular frame 1 by sliding into the U-shaped groove 16, the circular top plate 17 pushes against one end of the wheel axle 24 to restrict its axial movement, and the other end of the wheel axle 24 passes through the notch 9 and faces the hydraulic cylinder 6. The wheel 23 to be installed is placed on the support plate 10 between the hydraulic cylinder 6 and the limiting frame 3. At this time, the bearing support 13 is transferred to the side away from the wheel 23. Then, the hydraulic cylinder 6 drives the sleeve 7 to extend the disassembly and assembly tool 8, which is a variable diameter rod 8.2. The variable diameter rod 8.2 puts the bearing 25 of the wheel 23 onto the axle 24. The wheel set is flipped in the same direction. The same operation is performed, except that the circular top plate 17 supports the installed wheel 23. The bearing 25 of the other wheel 23 is put onto the other end of the axle 24, completing the installation of the wheel 24 onto the axle 24.

[0037] like Figure 5 , 6As shown, the process of disassembling the bearing 25 in this utility model is as follows: a wheel 23 is placed in reverse on the support plate 10 between the hydraulic cylinder 6 and the limit frame 3, with the rim of the wheel 23 facing the hydraulic cylinder 6. Figure 5 For the continuous operation of disassembling the axle 24, the axle 24 is still placed in the axle limiting block 15 on the support block 14, but the axle 24 is no longer connected to the wheel 23. The side of the wheel 23 opposite to the rim abuts against the side of the limiting frame 3. At this time, the bearing support 13 is moved to the side away from the wheel 23, and the movable frame 4 is no longer installed in the rectangular frame 1. Then, the hydraulic cylinder 6 drives the sleeve 7 to extend the disassembly tool 8, which is a variable diameter rod 8.2. The variable diameter rod 8.2 pushes the two bearings 25 out of the bearing holes of the wheel 23 and removes them into the notch 9, thus completing the disassembly of the bearings 25.

[0038] like Figure 7 , 8 As shown, the process of installing the bearing 25 in this utility model is as follows: a wheel 23 is placed on the support plate 10 between the hydraulic cylinder 6 and the limiting frame 3, the rim of the wheel 23 abuts against the side of the limiting frame 3, and the limiting rod 12 rotates to stop the rim of the wheel 23, restricting the axial movement of the wheel 23. Figure 7 For continuous operation of disassembling axle 24, axle 24 is still placed in axle limiting block 15 on support block 14, but axle 24 is no longer connected to wheel 23; At this time, using the bearing support 13, the inclined rod 13.2 is rotated on the vertical rod 13.1, and the arc plate 13.6 is moved to the wheel 23 on the side of the recess 9 of the limiting frame 3. Now, the end of the arc plate 13.6 facing the recess 9 is lifted, which is achieved by rotating the rotating block 13.5 on the rotating shaft 13.4. The end of the arc plate 13.6 is offset from the side end of the wheel 23. Then, the inclined rod 13.2 is pressed against the top of the side of the support plate 10 facing the head end of the rectangular frame 1 for limiting. Finally, the arc plate 13.6 is laid flat downwards, and the bottom of the rotating block 13.5 is pressed against the bottom of the groove 13.3 for limiting rotation. At this time, the arc plate 13.6 is aligned with the bearing hole of the wheel 23 and is close to it. Two bearings 25 are placed on the arc plate 13.6. Then, the hydraulic cylinder 6 drives the sleeve 7 to extend the disassembly and assembly tool 8, which is a variable diameter rod 8.2. The variable diameter rod 8.2 pushes the bearing 25 into the bearing hole of the wheel 23, completing the installation of the bearing 25 into the wheel 24.

[0039] Advantages: This new type of assembly and disassembly replaces manual labor. The wheel axle 24 and wheel 23 are supported by the limiting frame 3, support plate 10, support block 14, and wheel axle limiting block 15. Then, the hydraulic cylinder 6 is used to extend and retract to push out the wheel axle 24 and bearing 25 to achieve disassembly, or to press in the bearing 25 and wheel 23 to achieve installation. This saves manpower, reduces labor intensity, and improves efficiency. The bearing support 13 can support the bearing 25, which is conducive to the installation of the bearing 25 on the corresponding wheel 23.
