Description

Technical Field

[0001] The utility model relates to the technical field of mine car maintenance, and particularly relates to an anti-bullet piece for a tire sealing ring of an underground conveyor vehicle. Background Art

[0002] Mine engineering vehicles play a crucial role in mine exploitation, and the tires of mine engineering vehicles are subject to large losses. During the process of inflating or maintaining the tires, if the tires are over-inflated or have hidden damages, the tires are likely to explode and the tire retaining rings bounce outwards, thus leading to injury accidents. Moreover, due to the large size of the tires of mine engineering vehicles, the lethality of tire explosions is also large, and the harmfulness of injury accidents is also strong.

[0003] The patent network discloses a tire retaining device (publication number: CN 217022458 U), which belongs to the technical field of mine car maintenance and includes a connecting part, a blocking part, and a fixing part for fixing the blocking part to the connecting part. One end of the connecting part is fixed on the inner ring of the wheel hub, and the other end of the connecting part is a free end extending outwards. The blocking part is perpendicular to the connecting part. The blocking part includes a blocking main body, a blocking end arranged at one end of the blocking main body, and a mounting hole arranged on the blocking main body corresponding to the connecting part. The free end of the connecting part passes through the mounting hole of the blocking part and is connected to the fixing part. Among them, the blocking end of the blocking part extends towards the outer edge of the wheel and straddles the tire retaining ring, and is supported on the outside of the tire. It has the technical effects of simple structure, low cost, fewer personnel required, reducing the labor intensity of tire inflation operation, improving the safety of tire inflation operation, and thus improving the efficiency of the double-track operation.

[0004] The above technology can block the sealing retaining ring in the tire to prevent the sealing retaining ring from popping out and causing safety accidents. However, in the actual use process, the free end of the connecting part is located outside the tire, so the free end thread is easily worn, and even deformed due to collision. After wear and deformation, it is not convenient to disassemble the blocking part, and the connecting part needs to be replaced. Since the connecting part is welded to the wheel hub, it brings inconvenience to the maintenance work, and multiple welding operations also reduce the service life of the wheel hub. Therefore, there is room for improvement. Summary of the Utility Model

[0005] The utility model provides an anti-bullet piece for a tire sealing ring of an underground conveyor vehicle to solve the problems raised in the background art.

[0006] To solve the above problems, the present utility model provides an anti-bullet sheet for the tire sealing ring of an underground transporter, which includes a connecting bolt and an anti-bullet sheet. The connecting bolt is fixed in the inner ring of the wheel hub. A nut is threadedly connected to the threaded end of the connecting bolt. The anti-bullet sheet is Z-shaped, with one end being a connecting end and the other end being a blocking end. An installation hole matching the connecting bolt is formed in the connecting end. The anti-bullet sheet is sleeved on the connecting bolt through the installation hole and is fixedly connected to the inner ring of the wheel hub by the nut. The blocking end extends towards the outer edge of the wheel and crosses the wheel hub to abut against the outer side of the sealing ring.

[0007] Preferably: The anti-bullet sheet is integrally formed by pressing a steel plate.

[0008] Preferably: The outer edge corner of the blocking end of the anti-bullet sheet is arc-shaped.

[0009] Preferably: The connecting bolt is welded in the inner ring of the wheel hub.

[0010] The beneficial effects of adopting the above technical solutions are as follows:

[0011] 1. The connecting bolt is welded in the inner ring of the wheel hub. By cooperating with the installation hole in the connecting end of the Z-shaped anti-bullet sheet, the anti-bullet sheet can be fixed in the inner ring of the wheel hub, which can ensure that the connecting bolt is not exposed outside the vehicle tire, thereby preventing wear and deformation of the threaded end of the connecting bolt, prolonging the service life, and making the loading and unloading more convenient.

[0012] 2. Through the setting of the blocking end in the Z-shaped anti-bullet sheet, the blocking end can abut against the sealing ring, thereby preventing the sealing ring from popping out due to too high air pressure or explosion after the tire bears weight, causing potential safety hazards.

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0017] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] Such as Figure 1 , in this embodiment, an anti - bullet piece for a tire sealing ring of an underground transporter vehicle includes a connecting bolt 1 and an anti - bullet piece 2. The connecting bolt 1 is fixed in the inner ring of the wheel hub. A nut 3 is thread - connected in the threaded end of the connecting bolt 1. The anti - bullet piece 1 is Z - shaped, with one end set as a connecting end 21 and the other end set as a blocking end 22. An installation hole 211 matching the connecting bolt 1 is opened in the connecting end 21. The anti - bullet piece 2 is sleeved on the connecting bolt 1 through the installation hole 211 and is fixedly connected to the inner ring of the wheel hub through the nut 3. The blocking end 22 extends towards the outer edge of the wheel and straddles the wheel hub and abuts against the outside of the sealing ring.

[0019] Through the above - mentioned technical solution, the anti - bullet piece 2 is passed through the connecting bolt 1 through the installation hole 211 of the connecting end 21, and then the connecting end 21 of the anti - bullet piece 2 is fixedly connected to the connecting bolt 1 through the nut 3. Since the connecting bolt 1 is fixedly connected to the inner ring of the wheel hub, the anti - bullet piece 2 is connected to the wheel hub. Since the connecting bolt 1 is arranged inside the wheel hub, it is not easy to contact the outside world, and thus it is not easy to cause wear and deformation, extending the service life and making the loading and unloading of the anti - bullet piece 2 more convenient. Through the arrangement that the blocking end 22 of the anti - bullet piece 2 abuts against the sealing ring in the wheel, when the pressure of the tire is too high or the tire explodes and causes the sealing ring to pop out, the sealing ring can be blocked, thereby avoiding potential safety hazards caused by the popping out of the sealing ring.

[0020] Preferably, the anti - bullet piece 2 is integrally formed by pressing steel plates.

[0021] Through the above technical solution, the rigidity of the bulletproof piece 2 is improved, which can better block the sealing retaining ring and prevent it from popping out.

[0022] Preferably: the outer edge corner of the blocking end 22 of the bulletproof piece 2 is arc-shaped.

[0023] Through the above technical solution, it can be avoided that when the corner of the blocking end 22 in the bulletproof piece 2 contacts the tire, it will cause scratches on the tire surface or rub against the staff.

[0024] Preferably: the connecting bolt 1 is welded in the inner ring of the wheel hub.

[0025] Through the above technical solution, the connecting bolt 1 can be stably connected to the wheel hub.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, however, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention; the technologies not described in detail in the present invention are implemented with the prior art.
