[0002] Heavy trucks (referred to as heavy-duty trucks) are trucks used for transporting heavy goods or having a large load-carrying capacity, and are usually used in long-distance transportation, construction sites, mining operations, and other occasions that require high load-carrying capacity and strong power.

[0003] In vehicle maintenance projects, vehicle tire maintenance projects are inevitable. When maintenance personnel perform inflation operations on tires, if the maintenance personnel operate improperly during the tire inflation process or use damaged or improper inflation tools, it may lead to incorrect inflation pressure, and over-inflating the tire beyond the recommended pressure may cause the vehicle tire to explode. Especially for aging or damaged tires, they become fragile during inflation, and the explosion risk is higher. Since the tires of heavy-duty trucks are larger and have higher internal pressure compared to ordinary car tires, once an explosion occurs during the inflation process, the tire will release a huge amount of energy and fly out, which may cause injuries or serious casualties to personnel, especially to the staff in the vicinity.

[0004] Therefore, in order to prevent maintenance operators from being injured due to tire explosion, protect the safety of personnel's lives, and reduce hazards, it is a technical problem to be solved by those skilled in the art. Summary of the Invention

[0023] The following further elaborates on the utility model in conjunction with the attached drawings and specific implementation modes.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , a heavy truck tire inflation protection device, including a fixed base 1 and a placing platform 2 horizontally arranged on the fixed base 1, the placing platform 2 is used for placing the tire, the placing platform 2 is circular, and a plurality of columns 3 are vertically arranged on the placing platform 2, all the columns 3 are evenly distributed in a circular shape and are concentric with the placing platform 1; a cover plate 4 is detachably arranged above all the columns 3 to enclose the upper part of all the columns 4.

[0025] In this way, when using this protection device to inflate the tire, open the cover plate, horizontally place the tire on the placing platform, and then cover the cover plate above all the columns. The space formed by the placing platform, the cover plate and all the columns can limit the position of the tire, avoiding the tire flying out due to explosion during the inflation operation, thereby preventing maintenance operators from being injured by the tire explosion, protecting the safety of personnel's lives and reducing hazards.

[0026] Here, the cover plate can be fixedly connected to the column, or the cover plate and the placing platform can be fixedly connected, so as to fix the cover plate on the column, so that the cover plate, the placing platform, the column and the fixed base form a whole.

[0027] During specific implementation, grooves 6 corresponding to all the columns 3 are arranged on the upper surface of the placing platform 2, all the grooves 6 are arranged along the radial direction of the placing platform 2, and the lower ends of all the columns 3 are arranged in the corresponding grooves 6 and can horizontally move along the radial direction of the placing platform 2 to adjust the size of the circle formed by all the columns 3.

[0028] Here, the upright posts can move horizontally along the radial direction of the placing platform, so as to adjust the size of the circle formed by all the upright posts. In this way, this protection device can be used for the inflation operation of tires of various specifications. At the same time, during the inflation process of the tire, the upright posts limit the tire, thus preventing the tire from flying out in the horizontal direction. The upright posts can be horizontally moved along the groove by pneumatic control, or a horizontal connecting plate can be formed by bending the lower end of the upright post outwards, connection holes are arranged on the connecting plate, and at the same time, a number of fixing holes corresponding to the connection holes are arranged on the groove of the placing platform. The fixing holes are provided with multiple along the length direction of the groove (the positions of the fixing holes can be set according to the size of the tire specification), so that the connecting plate and the placing platform can be fixedly connected by using fixing parts such as screws, and then the upright posts and the placing platform can be fixed by connecting the connection holes and different fixing holes.

[0029] During specific implementation, the cover plate 4 is circular, the cover plate 4 is concentric with the circle corresponding to all the upright posts 3, and sliding grooves 10 corresponding to all the upright posts 3 are arranged on the lower surface of the cover plate. The sliding grooves 10 are arranged along the radial direction of the cover plate 4, and the upper ends of all the upright posts 3 are arranged in the corresponding sliding grooves 10, which is convenient for guiding the upright posts 3 during the moving process.

[0030] During specific implementation, the cover plate 4 is provided with a hollow structure. Specifically, as Figure 3 shown, the cover plate is composed of an annular plate, a central plate arranged at the center, and a number of connecting columns. The two ends of the connecting columns are respectively connected to the central plate and the annular plate correspondingly, and the connecting columns are evenly distributed. The sliding grooves are arranged on the lower surface of the connecting columns. Of course, a mesh grid can also be arranged between adjacent connecting columns.

[0031] Here, the cover plate is provided with a hollow structure, which is beneficial to reducing the weight while ensuring the strength, and is convenient for maintenance operators to remove the cover plate.

[0032] During specific implementation, a locking mechanism is further included. The locking mechanism includes a locking body 7 and a chain 8. One end of the chain 8 is connected to the locking body 7 and can be telescoped under the action of the locking body 7. A cavity for placing the locking body 7 is provided in the fixed base 1, the locking body 7 is fixedly arranged in the cavity, a through hole for the chain 2 to pass through is arranged on the placing platform 2, and a lock catch 9 cooperating with the chain 8 is arranged on the lower surface of the cover plate 4. The other end of the chain 8 passes through the through hole and is connected to the lock catch 9. In this way, the cover plate and the placing platform are detachably connected. At the same time, the locking mechanism here is similar to the principle of an automobile seat belt and belongs to the prior art, which is not limited here. When the tire flies out from above during the inflation process, the chain of the locking mechanism quickly tightens and stretches, preventing the tire from flying out from above.

[0033] During specific implementation, a handle 5 is arranged on the upper surface of the cover plate 4, which is convenient for taking and placing the cover plate 4. In this way, maintenance operators can hold the handle to take and place the cover plate, and the operation is more convenient.

[0034] In specific implementation, the fixed base 1 is a columnar structure in the shape of a frustum of a pyramid with a larger bottom and a smaller top. When installing the protection device, the fixed base 1 is buried underground, and the placement platform 2 is located on the ground. The fixed base can increase the contact area and the force-bearing capacity, and is also conducive to energy dissipation by the ground during the tire inflation process.

[0035] Finally, it should be noted that the above embodiments of the present utility model are only examples for explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes and modifications can be made based on the above description. It is impossible to list all the implementation manners here.
