[0050] In this embodiment: it should be supplemented that: the column frame 103 is made of aluminum material as a whole, so that the device is light and easy to move;

[0051] The universal wheel 102 can facilitate the transfer operation of the entire device. When the tire is disassembled, the entire device can be moved close to the tire, and the support rod 206 can be located under the tire. Then, the electric hydraulic rod 106 is started by the control button 104, so that the output end of the electric hydraulic rod 106 extends upward. At this time, the movable pulley 2014 on the top pushes the wire rope to pull the slide 2012 upward, and the slide 2102 drives the support unit to move upward as a whole (it should be supplemented that: at this time, the L-shaped limit rod 304 is in a backward contracted state, that is, away from the upper space of the support rod 206, so that it will not affect the contact between the support rod 206 and the tire).

Then, the height of the lifting column 302 is adjusted so that the horizontal part of the L-shaped limiting rod 304 is in contact with the upper surface of the tire. At this time, the second locking bolt 305 is tightened, and then the L-shaped limiting rod 304 is first moved horizontally and then rotated, so that the bent end of the L-shaped limiting rod 304 faces downward and is in contact with the side of the tire close to the vehicle body. At this time, the third locking bolt 306 is tightened;

[0053] After that, the fixing bolts of the tire can be removed, and the removed fixing bolts can be placed in the storage box 107. After all the fixing bolts are removed, the first locking bolt 211 can be loosened, and then the handle portion 208 is pulled. The handle portion 208 pulls the horizontal slide bar 204 and drives the entire support unit and the limiting assembly 3 to move outward (i.e., away from the vehicle body). At this time, the L-shaped limiting rod 304 has an outward pulling force on the tire, so that the tire is separated from the vehicle body shaft, and the support rod 206 supports the tire so that it does not fall off; in this way, the tire can be easily removed;

[0054] After that, the first locking bolt 211 can be tightened to keep the horizontal slide bar 204 fixed, and then the self-locking of the universal wheel can be released, and the entire device can be moved by holding the handle 208, so as to transfer the tire to the next station for maintenance operation.

[0055] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
