[0036] In this embodiment, the jacking device and the clamping assembly are provided, and the wheel hub 15 can be disassembled and assembled when the tire 14 is fixed by the clamping assembly. No special equipment is needed for disassembly and assembly, and the area occupied is small, the structure is more streamlined, the production cost is low, the purpose of disassembly and assembly of the tire 14 can be achieved, and it is more convenient to use.

[0037] In this embodiment, a plurality of universal wheels with brakes can be provided at the bottom of the base plate 1 to facilitate the movement of the entire device. When the tire 14 is to be disassembled or assembled, the entire device can be moved to a designated place to conveniently carry out the disassembly or assembly of the tire 14.

[0038] In an exemplary embodiment, the clamping assembly is a telescope 10, which is symmetrically arranged on the gantry 2 with the jack as the center. The extended end of the telescope 10 can be extended to make the tire 14 abut against the supporting assembly.

[0039] In this embodiment, Figure 1 As shown, the tire 14 of the wheel can be fixed by the provided retractor 10, so as to facilitate the disassembly or assembly of the hub 15 in the middle of the wheel. In this embodiment, there can be multiple retractors 10, which are used to generate uniform force on the tire 14 to ensure the stability of the disassembly and assembly process. In this embodiment, the number of retractors 10 is two, which are symmetrically arranged on the gantry 2.

[0040] For example, the retractor 10 in this embodiment is a cylinder, and further includes a gas source connector 5, the input end of the gas source connector 5 is provided with an air intake pipe 8, the output end of the gas source connector 5 is provided with an exhaust pipe 9, the air intake pipe 8 is connected to the air intake channel of the cylinder, and the exhaust pipe 9 is connected to the exhaust channel of the cylinder. In order to realize the parallel connection of the two cylinders, a three-way connector is used to realize the gas source conversion, so that the gas source can enter the two cylinders and realize exhaust at the same time.

[0041] For example, in this embodiment, the gas source connector 5 is provided with a gas source pipe 6 for connecting the gas source, and the gas source connector 5 is provided with a manual switch 7. Through the provided gas source pipe 6, the gas source can be introduced to control the operation of the cylinder, and the provided manual switch 7 can conveniently open or close the cylinder. At the same time, the cylinder can also be controlled by a PLC controller to realize intelligent control without the need for an operator to manually start or shut down.

[0042] It is worth noting that the air intake pipe 8 and the exhaust pipe 9 in this embodiment are fixed to the gantry 2 through air pipe clips to provide stable power.

[0043] It should also be noted that the inner side wall of the gantry 2 in this embodiment is also provided with a reinforcement plate, which is mainly used to strengthen the connection between the telescopic device 10 and the gantry 2 to ensure the normal operation of the telescopic device 10.

[0044] In an exemplary embodiment, the support assembly includes a pressure plate 11 and a pressure block 12. The pressure plate 11 can cooperate with the wheel hub 15.

[0045] When the tire 14 and the wheel hub 15 are disassembled, the pressure plate 11 supports the tire 14 from the bottom, the pressure block 12 is placed above the wheel hub 15, the extended end of the jacking device is extended to the disassembly position, and the wheel hub 15 is separated from the tire 14;

[0046] When assembling the tire 14 and the wheel hub 15 , the pressure plate 11 supports the tire 14 from the bottom, the pressure block 12 is placed above the wheel hub 15 , the extended end of the jacking device is extended to the disassembly position, and the wheel hub 15 is clamped into the tire 14 .

[0047] In this embodiment, the tire 14 is supported by the pressure plate 11 to respectively realize the disassembly or assembly of the wheel hub 15 and the tire 14 during actual use.

[0048] It is worth mentioning that in the present embodiment, when the tire 14 and the wheel hub 15 are disassembled, since there is a wheel hub 15 retaining ring between the tire 14 and the wheel hub 15, it is necessary to remove the wheel hub 15 retaining ring in advance before the tire 14 and the wheel hub 15 are completely separated. Specifically: before disassembling the tire 14 and the wheel hub 15, the pressure block 12 is placed at the bottom to support the inner surface of the wheel hub 15, the pressure plate 11 is placed on the tire 14, the lifting device is adjusted to press down the pressure plate 11, and when a gap is generated between the tire 14 and the wheel hub 15, the wheel hub 15 retaining ring is pried out with a crowbar-like tool.

[0049] It should also be noted that in this embodiment, after assembling the tire 14 and the wheel hub 15, it is also necessary to install the wheel hub 15 retaining ring between the wheel hub 15 and the tire 14. Specifically: the pressure block 12 is placed at the bottom to support the inner surface of the wheel hub 15, the pressure plate 11 is placed above the tire 14, and the wheel hub 15 retaining ring is placed on the tire 14. The lifting device presses the pressure plate 11 to create a gap between the tire 14 and the wheel hub 15, and the wheel hub 15 retaining ring is pried in with a crowbar-like tool.

[0050] In an exemplary embodiment, the supporting plate 11 includes a first contact plate 1101 and a second contact plate 1103 , and a plurality of connecting posts 1102 are disposed between the first contact plate 1101 and the second contact plate 1103 .

[0051] In this embodiment, the first contact plate 1101 and the second contact plate 1103 are used to contact the tire 14 and the bottom plate 1 respectively, so that the pressure plate 11 as a whole can stably support the wheel to ensure the stability of the tire 14 during assembly and disassembly.

[0052] For example, Figure 5 As shown, an escape channel 1104 is provided between the first contact plate 1101 and the second contact plate 1103. The escape channel 1104 is used for the hub 15 to pass through when the wheel is removed. The diameter of the escape channel 1104 is larger than the maximum diameter of the hub 15. When the tire 14 is removed, the tire 14 eventually stays on the pressure plate 11, and the hub 15 eventually passes through the escape channel 1104 and falls on the bottom plate 1, located inside the pressure plate 11. The hub 15 can be taken out by moving the pressure plate 11 away. Similarly, Figure 6 As shown, during installation, the wheel hub 15 is placed above the tire 14 , and the wheel hub 15 is pressed in by the action of the pressing block 12 , and the assembled wheel is finally placed flat on the supporting plate 11 .

[0053] In an exemplary embodiment, the jacking device is a hydraulic cylinder 3, which is detachably connected to the gantry 2. The extended end of the hydraulic cylinder 3 is detachably connected to a pressure plate 4, which can cooperate with the jacking block 12 to drive the wheel hub 15 to detach from or install the tire 14.

[0054] In this embodiment, by setting the pressure plate 4, the jacking device can be prevented from directly contacting the wheel hub 15 during the process of pressing down the jacking device, and the jacking block 12 is installed on the flange on the inner side of the wheel hub 15 when assembled with the wheel hub 15. When the pressure plate 4 is pressed down, it can drive the jacking block 12 to move synchronously, and the jacking block 12 increases the contact area with the wheel hub 15, and realizes uniform force on the wheel hub 15, thereby realizing the disassembly and assembly of the wheel hub 15.

[0055] For example, in this embodiment, the pressure plate 4 and the top pressure block 12 can be installed and matched by means of snap connection, hole-shaft matching, etc., to improve the stability of the driving force.

[0056] In an exemplary embodiment, the extended end of the retractor 10 is detachably connected with a pressure ring 13 , and the pressure ring 13 is sleeved on the extended end of the retractor 10 for contacting the tire 14 .

[0057] In this embodiment, the pressure ring 13 provided at the extended end of the cylinder can increase the contact area and make the force on the tire 14 more uniform.

[0058] Exemplarily, the pressure ring 13 in this embodiment is a rubber pressure ring 13 , which can be sleeved on the extended end of the cylinder. The pressure ring 13 made of rubber can prevent the tire 14 from being damaged.

[0059] In summary, in this embodiment, the wheel can be fixed by the clamping assembly and the supporting assembly, and the tire 14 can be disassembled and assembled by the jacking device, without the need to transport the tire 14 to special equipment for disassembly and assembly, thereby achieving quick and convenient disassembly and assembly of the tire 14.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
