[0052] The tire removing assembly 514 is relatively mounted on both sides of the base 511, and the tire removing assembly 514 and the support frame 512 are located on the same side of the base 511. Each tire removing assembly 514 includes a first bracket 5141, an angle bracket 5142, a cylinder assembly 5143 and a claw 5144. The first bracket 5141 is mounted on the side of the base 511 and is located between the two support frames 512. The angle bracket 5142 is slidably mounted on the first bracket 5141. The cylinder assembly 5143 is fixed on the angle bracket 5142, and the claw 5144 is connected to the cylinder assembly 5143. The distance between the relative claws 5144 is adjusted by the cylinder assembly 5143. By adjusting the position of the angle bracket 5142, the claw 5144 is extended into the tire cavity, and the cylinder assembly 5143 provides an outward pulling force, so that the damaged point is exposed as much as possible, which is convenient for tire repairing. The claws 5144 can also clamp the two sides of the tire through the cylinder assembly 5143 to fix the tire. The tire lifting assembly 514 also includes an air filling nozzle 5145, which is fixed to the top of the first bracket 5141 and is used to cooperate with the air filling mechanism 60 to inflate the tire. It can be understood that the tire lifting assembly 514 can be installed on one or more of the auxiliary machine bases 12 according to needs.

[0053] The twelfth motor 52 is fixed to a side of the auxiliary base 12 away from the main base 11 . The twelfth motor 52 drives the base 511 to rotate via a rotating shaft, so as to change the position of the tire and the side orientation of the tire.

[0054] The inflation mechanism 60 includes a second bracket 61 and an air tank 62. The second bracket 61 is fixed to the auxiliary machine base 12 and is located on the same side as the twelfth motor 52. The air tank 62 is mounted on the second bracket 61. The air tank 62 is connected to the inflation nozzle 5145 through a hose, and an air valve is connected to the hose. The operator can control the air valve to complete the inflation at a safe distance. It can be understood that the air valve can also be controlled to open and close by a controller.

[0055] The wheel maintenance device 100 can realize multiple functions, such as tire changing, tire repairing, tire transposition, etc. Most buses, trucks and other large and medium-sized vehicles have single front wheels and double rear wheels. The wheel maintenance device 100 is not only suitable for small passenger cars, but also for large vehicles such as trucks and buses.

[0056] When in use, first position it, specifically move the wheel maintenance device 100 to the vicinity of the wheel to be maintained, make the long side of the main machine base 11 roughly parallel to the side of the vehicle and adjust the distance from the side of the wheel to a suitable position, adjust the position of the multi-claw chuck 4224 so that its center is roughly coaxial with the wheel axle, lock the universal wheel 114, and fix the position of the wheel maintenance device 100.

[0057] Then, the wheel is unloaded. The nut on the wheel is unloaded by the nut disassembly and assembly mechanism 20. The baffle plate 313 or the clamping hook 314 is selected according to the specific situation. The distance between the relative baffle plates 313 or the clamping hook 314 is adjusted by the fixed mechanical arm assembly 423 and the rotating mechanical arm assembly 424 to adapt to the wheel. The tire is unloaded by controlling the fourth slide 432 and the sixth slide 442 to move away from the wheel on the corresponding slide rail frame. When the baffle plate 313 is used to unload the tire, the inner hole of the wheel rim is clamped by the multi-claw chuck 4224, and the unloaded wheel is clamped by the multi-claw chuck 4224. When the clamping hook 314 is used to unload the tire, after the wheel is unloaded, the wheel is first placed on the tire rack 51 by the rotating translation mechanism 41, and then the distance between the clamping hooks 314 is increased, and then the unloaded wheel is clamped by the multi-claw chuck 4224.

[0058] When changing a tire, the tire is removed through the tire removal mechanism 43, the removed tire is placed on the tire rack 51 through the rotation and translation mechanism 41, and the new tire is placed in another tire rack 51. The tire is installed through the rotation and translation mechanism 41 and the tire installation mechanism 44, and inflated through the inflation mechanism 60. The wheel is reinstalled on the wheel through the rotation and translation mechanism 41, the multi-claw chuck 4224 and the disassembly and assembly nut mechanism 20.

[0059] When repairing a tire, the tire is removed by the tire disassembly mechanism 43, and the removed tire is placed on the tire rack 51 by the rotation and translation mechanism 41 for manual repair, and then the tire is installed by the rotation and translation mechanism 41 and the tire installation mechanism 44, and then the wheel with the tire is placed on the tire rack 51 by the rotation and translation mechanism 41, and inflated by the inflation mechanism 60, and the wheel is reinstalled on the vehicle by the rotation and translation mechanism 41, the multi-claw chuck 4224 and the disassembly and assembly nut mechanism 20. It can be understood that when repairing a double-layer wheel, after the outer wheel is processed, it is placed on the tire rack 51, and the above steps are repeated to repair the inner wheel.

[0060] When the front and rear tires are swapped, after the front wheel is positioned and unloaded, the unloaded front wheel is placed in the tire rack 51 through the multi-claw chuck 4224 and the rotating and translating mechanism 41, and the wheel maintenance device 100 is moved to the rear wheel position for positioning and unloading. Then, the unloaded rear wheel is placed in another tire rack 51 through the multi-claw chuck 4224 and the rotating and translating mechanism 41, and the front wheel is installed at the rear wheel position through the rotating and translating mechanism 41, the multi-claw chuck 4224 and the disassembling and nut mechanism 20, and then the wheel maintenance device 100 is moved to the front wheel position, and the rear wheel is installed at the front wheel position through the rotating and translating mechanism 41, the multi-claw chuck 4224 and the disassembling and nut mechanism 20.

[0061] It can be understood that the wheel maintenance device 100 can not only perform the above-mentioned front and rear tire swap, but also perform the inside-outside swap of a double-layer wheel and the swap of the outer wheel or the inner wheel in a double-layer tire with the front and rear wheels.

[0062] The wheel maintenance device 100 integrates the functions of wheel loading and unloading, tire loading and unloading, repairing, tire changing, and transposition through the cooperation between various components. It is easy to move and operate, adopts mechanized operation, is easy to operate, reduces labor intensity and operation difficulty, and is highly efficient and safe.
