[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0029] As Figure 1 、 Figure 2 、 Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b shown, in the normal working state, in a system using a three-in-one reduction motor to drive the running mechanism, the hollow shaft sleeve of the three-in-one reduction motor 10 is sleeved on the running mechanism wheel shaft 20 and fastened by a locking disc. The three-in-one reduction motor 10 is supported and fixed by a torque arm 110 and a connecting pin shaft. The disassembly and transfer device for the three-in-one reduction motor of the present invention is used to remove the three-in-one reduction motor 10 from the running mechanism wheel shaft 20 and transfer it to a maintenance location. The disassembly and transfer device for the three-in-one reduction motor includes: a bottom vehicle 1, an upper vehicle 2, a disassembly and clamping assembly 3, and a height adjustment assembly 4. The upper vehicle 2 is supported on the bottom vehicle 1, the disassembly and clamping assembly 3 is supported on the upper vehicle 2, and the height adjustment assembly 4 is arranged at the four corners of the bottom vehicle 1 and is threadedly connected to the bottom vehicle 1.

[0030] For the convenience and clear description of the disassembly and transfer device for the three-in-one reduction motor of the present invention, specifically as Figure 1 shown, the axial direction of the running mechanism wheel shaft 20 is defined as the Y direction, that is, the left-right direction of the drawing; the transverse direction perpendicular to the axial direction of the running mechanism wheel shaft 20 is defined as the X direction, that is, the front-back direction of the drawing; the height direction perpendicular to the bottom vehicle 1 is defined as the Z direction, that is, the up-down direction of the drawing.

[0031] The bottom vehicle 1 is of a rigid frame structure, including two oppositely arranged beams 110, two opposite tracks 120 sunken between the two beams 110, and four groups of bottom wheel assemblies 130 connected to the four ends of the two beams 110 through axles. The rotation of the bottom wheel assemblies 130 can drive the bottom vehicle 1 to perform a lateral movement perpendicular to the axial direction of the running mechanism wheel axle 20, thereby realizing the lateral movement of the entire disassembly and transfer device, that is, the movement along the X direction. The driving mode of the bottom wheel assemblies 130 can be manual or electric.

[0032] The upper vehicle 2 includes an upper vehicle frame 210, upper wheel assemblies 220, a pallet 230, and support blocks 240. The upper vehicle frame 210 is assembled from multiple plate members. The pallet 230 is arranged on the upper vehicle frame 210. The support blocks 240 are arranged on the pallet 230 to support the bottom of the three-in-one reduction motor 10 to be disassembled. The upper wheel assemblies 220 are located below the pallet 230 and are connected to the four corners of the upper vehicle frame 210 through axles. The upper wheel assemblies 220 are arranged to be movable on the two tracks 120 of the bottom vehicle 1, thereby realizing the movement of the upper vehicle 2 along the axial direction of the running mechanism wheel axle 20, that is, the movement along the Y direction.

[0033] The disassembly and clamping assembly 3 includes disassembly bolts 310, movable top blocks 320, a flat plate 330, ejector rods 340, and a clamping frame 350. Threaded holes matching the disassembly bolts 310 are machined in the middle of the flat plate 330. The screw rod of the disassembly bolt 310 is inserted into the threaded hole, and thus is connected to the flat plate 330 through a thread pair. A blind hole is provided on one end face of the movable top block 320. The end of the screw rod of the disassembly bolt 310 is inserted into the blind hole of the movable top block 320. The disassembly bolt 310 and the movable top block 320 can rotate relative to each other. At the same time, when in use, the end face of the movable top block 320 without the blind hole contacts and abuts against the end face of the running mechanism wheel axle 20. A plurality of ejector rods 340 are arranged around the threaded hole. One end of the ejector rod 340 is rigidly connected to the flat plate 330, and the other end of the ejector rod 340 is rigidly connected to the clamping frame 350. The lower part of the clamping frame 350 is connected to the pallet 230 of the upper vehicle 2.

[0034] The clamping frame 350 is a detachable structure assembled from multiple flat plates and can be assembled according to the shape and size of the three-in-one reduction motor 10 to be disassembled. As a specific implementation, the main structure of the clamping frame 350 is composed of, for example, two opposite side plates 350.2 and a vertical plate 350.1 perpendicular to the two side plates 350.2 and connecting the two side plates 350.2 together. The two side plates 350.2 and a vertical plate 350.1 enclose a shape with one side open, which can fix three faces of the three-in-one reduction motor 10 to be disassembled. At the lower part of each side plate 350.2, there is a slat 350.3, and the clamping frame 350 can be connected to the pallet 230 of the upper vehicle 2 through the slat 350.3 and the bolt connectors arranged thereon.

[0035] The height adjustment assembly 4 arranged at the four corners of the bottom vehicle 1 and threadedly connected to the bottom vehicle 1 can be, for example, a height adjustment bolt, thereby realizing the up and down movement of the bottom vehicle 1 and thus the entire disassembly and transfer device, that is, the movement along the Z direction, so as to adjust the height of the disassembly and transfer device.

[0036] The working process of the disassembly and transfer device for the three-in-one reduction motor of the present invention is as follows:

[0037] When it is necessary to disassemble the three-in-one reduction motor 10 from the running mechanism wheel shaft 20 and transfer it to the maintenance location, the assembled bottom vehicle 1, upper vehicle 2, and height adjustment assembly 4 are moved along the transverse direction perpendicular to the axial direction of the running mechanism wheel shaft 20, that is, the X direction, to the position below the three-in-one reduction motor 10 to be disassembled through the bottom wheel assembly 130, and the shrinkage disc used to fasten the hollow shaft sleeve and the running mechanism wheel shaft 20 on the three-in-one reduction motor 10 is removed;

[0038] The bottom vehicle 1 is manually raised through the height adjustment assembly 4, so that the pallet 230 is lifted until the support block 240 on the pallet 230 is in stable contact with the bottom of the three-in-one reduction motor 10. At this time, the bottom wheel assembly 130 leaves the ground, and the connecting pin shaft on the support torque arm 110 of the three-in-one reduction motor 10 is removed;

[0039] The disassembly and clamping assembly 3 is installed on the upper vehicle 2, and the three faces of the three-in-one reduction motor 10 are fixed by using the clamping frame 350, thereby effectively clamping and fixing the three faces and the bottom face of the three-in-one reduction motor 10, a total of four faces.

[0040] Rotate the disassembly bolt 310 so that the movable top block 320 abuts against the end face of the running mechanism wheel shaft 20, and the ejector rod 340 is rigidly connected between the flat plate 330 and the clamping frame 350. Thus, with the rotation of the disassembly bolt 310, through the screw side effect between the flat plate 330 and the disassembly bolt 310, the bonding force between the hollow shaft sleeve of the three-in-one reduction motor 10 and the running mechanism wheel shaft 20 is overcome, causing the running mechanism wheel shaft 20 to move axially, i.e., in the Y direction, and gradually disengage from the hollow shaft sleeve of the three-in-one reduction motor 10. At the same time, during the process of rotating the disassembly bolt 310 to gradually disengage the running mechanism wheel shaft 20, the upper wheel assembly 220 moves along the two tracks 120 of the bottom vehicle 1 in a direction opposite to the movement direction of the running mechanism wheel shaft 20, thereby finally removing the three-in-one reduction motor 10 from the running mechanism wheel shaft 20;

[0041] Lower the bottom vehicle 1 through the height adjustment assembly 4 to make the bottom wheel assembly 130 land on the ground, and move the disassembly and transfer device carrying the three-in-one reduction motor 10 to the maintenance location through the bottom wheel assembly 130 to complete the disassembly and transfer of the three-in-one reduction motor 10.

[0042] In summary, compared with the prior art, the disassembly and transfer device for a three-in-one reduction motor of the present invention has the following advantages and beneficial effects:

[0043] 1. By adopting the method of combining wheel rotation with bolt pair rotation, it realizes adjustment in three spatial directions and can effectively overcome the bonding force between the hollow shaft sleeve and the wheel shaft, facilitating the disassembly of the three-in-one reduction motor;

[0044] 2. The tracks for the upper vehicle are arranged in a sunken manner and form a frame structure with the beam, effectively compressing the height dimension of the device, and adopting the operation method from below to adapt to the situation where hoisting from above is not possible due to height restrictions or obstacles above the three-in-one reduction motor;

[0045] 3. Effectively fix the four faces of the three-in-one reduction motor, which can effectively prevent the three-in-one reduction motor from tipping over or even falling during disassembly and transfer, and can also avoid scratching or damaging the three-in-one reduction motor and the wheel shaft during disassembly and transfer.
