[0024] The following further elaborates on the technical features of the present invention in conjunction with the drawings and specific embodiments.

[0025] As shown in the figure, the utility model relates to a special-shaped tire mounting device, which includes a base 1, and an expandable tire mounting component is provided on the base 1. The expandable tire mounting component of the present application adopts a structure design similar to that of umbrella ribs. After the power mechanism moves, the structural tire can be expanded from the inner ring of the structural tire, so that the inner ring size of the structural tire increases, facilitating the sleeving of the structural tire on the wheel hub.

[0026] Specifically, the expandable tire mounting component of the present application includes a central power component 2, a plurality of expansion rods 3, a plurality of lower connecting rods 4, and a plurality of positioning rods 5.

[0027] Among them, all the expansion rods 3 are evenly distributed in a ring around the central power component 2. The central power component 2 has a power output part 201, and the power output part 201 moves relative to the central power component 2. There is an expansion link mechanism between the expansion rod 3 and the power output part 201 of the central power component 2. When the power output part 201 moves relative to the central power component 2, the expansion link mechanism pushes the expansion rod 3 to move away from the central power component 2.

[0028] The central power component 2 of the present application can be an oil cylinder, a cylinder, a jack or an electric cylinder. The power output part 201 is the piston top part of the central power component 2. When the piston of the power output part 201 ejects from the cylinder body of the power output part 201, the piston pushes the expansion rod 3 to move away from the central power component 2, and the ends of all the expansion rods 3 expand outwards, enlarging the inner ring size of the structural tire.

[0029] All the lower connecting rods 4 are evenly distributed in a ring around the central power component 2. The lower connecting rods 4 are arranged in cooperation with the expansion rods 3, and each lower connecting rod 4 is connected to one expansion rod 3. One end of the lower connecting rod 4 is hinged to the base 1, and the other end of the lower connecting rod 4 is hinged to the end of the expansion rod 3 close to the base 1.

[0030] Since the lower connecting rod 4 is hinged to the end of the expansion rod 3, in order to prevent the reverse expansion of the hinge joint, a positioning ring 5 is provided in the present application. In this embodiment, the positioning ring 5 is formed by bending a steel bar into a ring shape and then butt-welding and fixing the two end portions. During use, the positioning ring 5 is sleeved on the special-shaped tire mounting device of the present application. The positioning ring 5 should be located at the hinge joint between the lower end of the expansion rod 3 and the lower connecting rod 4, and the inner diameter of the positioning ring 5 should be slightly smaller than the maximum outward expansion range of the hinge joint between the expansion rod 3 and the lower connecting rod 4. During the use process, the positioning ring 5 restricts the position of the hinge joint between the expansion rod 3 and the lower connecting rod 4, preventing the hinge joint between the expansion rod 3 and the lower connecting rod 4 from expanding outwards.

[0031] A plurality of adjustment parts 101 are fixed on the base 1, and the adjustment parts 101 are arranged in cooperation with the lower connecting rod 4, that is, each lower connecting rod 4 is equipped with an adjustment part 101, and a plurality of hinge holes are constructed on the adjustment part 101. In this embodiment, the adjustment part 101 adopts a steel plate welded to the base 1, and the hinge holes on the adjustment part 101 are realized by punching holes in the steel plate.

[0032] The end of the lower connecting rod 4 is hinged to one of the hinge holes of the adjusting portion 101 through a hinge shaft. In this way, the hinge position of the lower connecting rod 4 can be adjusted, and lower connecting rods 4 of different sizes can be conveniently connected to meet different support requirements.

[0033] The expansion link mechanism includes a link 1 601 and a link 2 602. One end of the link 1 601 is fixed to the power output unit 201, the other end of the link 1 601 is hinged to the end of the link 2 602, and the end of the link 2 602 away from the link 1 601 is hinged to the middle section of the expansion rod 3.

[0034] Existing solid tires generally have openings arranged along the sidewalls to reduce tire mass and ensure structural strength. When applying, the ends of the expansion rods 3 of the present application are inserted into the openings on the tire sidewalls, and each expansion rod 3 is inserted into one opening. At this time, the connecting rod 1 601 and the connecting rod 2 602 are arranged at an obtuse angle, and the connecting rod 1 601 is located as a whole below the hinge between the connecting rod 2 602 and the expansion rod 3. Start the power output unit 201, so that the piston of the power output unit 201 is pushed out from the cylinder body of the power output unit 201, and the piston of the power output unit 201 drives the connecting rod 1 601 to move upward. During this process, the angle between the connecting rod 1 601 and the connecting rod 2 602 gradually increases, and can be increased to a maximum of 180 degrees. The connecting rod 2 602 pushes the expansion rod 3 to move away from the power output unit 201, especially the upper end of the expansion rod 3 expands outward, and the upper ends of the entire expansion rod 3 expand the tire, and the inner diameter of the inner ring of the tire is expanded to facilitate the insertion of the wheel hub.

[0035] After the wheel hub is put in, the piston of the power output unit 201 is started to move into the cylinder of the power output unit 201, and the upper ends of all the expansion rods 3 are retracted toward the power output unit 201. The tire is retracted under the action of the elastic restoring force, and the inner diameter of the inner ring of the tire is reduced, so that the tire is stuck on the wheel hub. After the tire is completely retracted and firmly stuck on the wheel hub, the tire and the wheel hub are removed from the special-shaped tire installation device of the present application, and the tire installation process is completed.

[0036] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
