Description

Technical Field

[0001] This utility model relates to the field of tire protection shell technology, and in particular to a tire protection shell. Background Technology

[0002] In steel plant production operations, engineering vehicles are core tools for ensuring raw material transportation, waste slag removal, and equipment scheduling. The integrity of their tires directly affects operational efficiency and production continuity. However, the working environment in steel plants is extremely harsh, and the production process generates a large amount of high-temperature splashes, such as molten iron overflowing during steelmaking and high-temperature steel slag falling from the hot rolling process. These substances can reach temperatures of hundreds or even thousands of degrees Celsius. Once they splash onto the surface of engineering vehicle tires, they can easily cause the tire rubber to melt and carbonize instantly, resulting in irreversible burn damage. However, existing steel mill engineering vehicles have significant shortcomings in tire protection. Some steel mills only use simple tire wear-resistant coatings or ordinary rubber sheaths for protection. While wear-resistant coatings can improve the wear resistance of the tire surface, they cannot protect against direct burns from high-temperature splashes. When molten iron comes into contact with the coating, it will still quickly conduct heat to the rubber tire, causing tire damage. Ordinary rubber sheaths have poor heat resistance and are prone to softening, deformation, or even ignition at high temperatures, thus losing their protective function. Utility Model Content

[0003] In view of the technical problem that existing steel plant engineering vehicles have shortcomings in tire protection, this utility model provides a tire protection shell.

[0004] The technical solution adopted by this utility model is: a tire protective shell, including a first protective shell and a second protective shell. The first and second protective shells are cylindrical cavity structures. One end of the first protective shell is provided with an opening. Multiple sets of wear-resistant plates are detachably and fixedly connected to the annular side of the first and second protective shells. Multiple sets of protective protrusions are fixedly connected to the outside of the wear-resistant plates.

[0005] A further feature of this invention is that the wear-resistant plate and the exterior of the first and second protective shells are provided with multiple sets of threaded holes, and fixing bolts are threaded into the threaded holes.

[0006] A further feature of this invention is that the anti-slip protrusions and the wear-resistant plate are an integral structure, and the anti-slip protrusions are distributed in an array at intervals on the outer surface of the wear-resistant plate.

[0007] A further feature of this invention is that the wear-resistant plate is made of high manganese steel or wear-resistant cast iron.

[0008] A further feature of this invention is that a rubber pad is fixedly connected to the inner cavity of the first protective shell.

[0009] A further feature of this invention is that each of the wear-resistant plates has at least three protective protrusions fixedly connected to its exterior.

[0010] A further feature of this invention is that a protruding ring is fixedly connected to the opening.

[0011] The beneficial effects of this utility model are as follows: This utility model solves the problem of tires of steel plant engineering vehicles being easily scalded and having insufficient protection. The first protective shell adopts a cylindrical cavity structure to wrap the tire, and together with the wear-resistant plate, it can directly block splashes of high-temperature molten iron, steel slag and other materials, and prevent the tire rubber from being scalded and melted. Compared with traditional wear-resistant coatings and ordinary rubber sleeves, the heat resistance and wear resistance are greatly improved, and the problem of high-temperature protection failure is completely solved.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0016] To address the problems existing in the background art, this application proposes the following technical solution: a tire protective shell, including a first protective shell 1 and a second protective shell 7, a rubber pad is fixedly connected to the inner cavity of the first protective shell 1, the first protective shell 1 and the second protective shell 7 are cylindrical cavity structures, an opening 2 is provided at one end of the first protective shell 1, a protruding ring is fixedly connected to the opening 2, and multiple sets of wear-resistant plates 3 are detachably fixedly connected to the annular side of the first protective shell 1, and multiple sets of protective protrusions are fixedly connected to the outside of the wear-resistant plates 3.

[0017] The first protective shell 1 and the second protective shell 7 serve as the core framework for tire protection. Their cylindrical cavity structure perfectly conforms to the circular contour of the tire, completely encasing it and forming a comprehensive physical protective barrier to prevent direct exposure to harsh environments. The first and second protective shells 1 and 7 interlock to enclose the tire, and are then secured by the wear-resistant plate 3. This allows operators to quickly assemble the tire and protective shell without complex disassembly procedures. The protruding ring fixed at the opening 2 further optimizes the assembly experience. The ring not only limits the tire's installation position, preventing axial displacement within the protective shell, but also enhances the structural strength of the opening 2's edges, preventing deformation or cracking due to impacts during long-term use and extending the service life of the first protective shell 1.

[0018] The rubber pads fixed inside the first protective shell 1 and the second protective shell 7 form a buffer line to protect the tire. The rubber material itself has excellent elasticity and flexibility. When the first protective shell 1 is subjected to external impact (such as the impact of iron slag splashed in a steel plant or the scraping of ground protrusions), the rubber pads can absorb the impact force through their own elastic deformation, converting the impact force into elastic potential energy, and preventing the impact force from being directly transmitted to the tire surface.

[0019] Multiple sets of wear-resistant plates 3, detachably connected to the annular sides of the first protective shell 1 and the second protective shell 7, are designed to withstand the damage to tires caused by sharp objects and high temperatures, especially in the harsh working environment of steel plants. The wear-resistant plates 3 directly block these external injuries, concentrating the wear and impact on the first and second protective shells 1 and 7, preventing premature damage. The detachable connection design means that when the wear-resistant plates 3 are severely worn or damaged, it is not necessary to replace the entire first protective shell 1; only the damaged wear-resistant plate 3 needs to be removed and replaced. This significantly reduces maintenance costs and replacement cycles, improving the economic efficiency of both the first and second protective shells 1 and 7.

[0020] Multiple sets of protective protrusions fixed to the exterior of the wear-resistant plate 3 further enhance the protective effect. These protrusions increase the contact gap between the wear-resistant plate 3 and external objects. When objects such as splashing hot molten iron or sharp gravel approach, the protrusions will first contact these objects, blocking or guiding them to the side, reducing the direct contact area between the object and the surface of the wear-resistant plate 3, and slowing down the wear rate. Simultaneously, the protective protrusions also enhance the impact resistance of the wear-resistant plate 3 surface, dispersing localized stress and preventing dents or cracks from concentrated stress in a single area. Furthermore, the presence of the protective protrusions also improves the overall anti-slip performance of the protective shell to a certain extent, especially on wet or muddy roads, reducing slippage between the protective shell and the ground, indirectly ensuring the stability of the engineering vehicle.

[0021] The wear-resistant plate 3, as well as the outer surfaces of the first protective shell 1 and the second protective shell 7, are provided with multiple sets of threaded holes 6, and the threaded holes 6 are threaded with fixing screws. The anti-slip protrusions 4 are integral with the wear-resistant plate 3. The anti-slip protrusions 4 are distributed in an array at intervals on the outer surface of the wear-resistant plate 3. The wear-resistant plate 3 is made of high manganese steel or wear-resistant cast iron. Each wear-resistant plate 3 has at least three protective protrusions fixedly connected to its outer surface.

[0022] The wear-resistant plate 3 is detachably connected to the first protective shell 1 and the second protective shell 7 via threaded holes 6 and fixing bolts 5. This connection method offers the dual advantages of secure installation and convenient disassembly. The fixing bolts 5 tightly fix the wear-resistant plate 3 to the sides of the first protective shell 1 and the second protective shell 7 through threaded engagement, which can withstand the vibration and impact generated during the operation of engineering vehicles, preventing the wear-resistant plate 3 from loosening or falling off during use. At the same time, when it is necessary to replace the wear-resistant plate 3, simply unscrew the fixing bolts 5 to remove the old wear-resistant plate 3, replace it with a new wear-resistant plate 3, and then retighten the bolts. The operation is simple and requires no special tools, reducing the difficulty of the operator's work. The multiple sets of threaded holes 6 ensure that the stress distribution between the wear-resistant plate 3 and the first protective shell 1 and the second protective shell 7 is uniform, avoiding deformation of the wear-resistant plate 3 due to uneven stress caused by missing bolts in some areas, further improving the connection stability.

[0023] The anti-slip protrusions 4 and the wear-resistant plate 3 adopt an integrated structural design. Compared with traditional welding or bonding methods, this completely eliminates connection gaps, enhances the connection strength between the anti-slip protrusions 4 and the wear-resistant plate 3, and prevents the anti-slip protrusions 4 from falling off under impact. The integrated structure also ensures the dimensional accuracy and positional precision of the anti-slip protrusions 4, providing a guarantee for subsequent array-style distribution. The anti-slip protrusions 4 are distributed in an array at intervals, ensuring uniform coverage of the wear-resistant plate 3 surface and avoiding blind spots. Regardless of the direction of impact from external objects, corresponding protective protrusions can provide a blocking effect. At the same time, the uniform interval distribution also reduces stress concentration on the surface of the wear-resistant plate 3, extending the service life of the wear-resistant plate 3.

[0024] Wear-resistant plate 3 is made of high-manganese steel or wear-resistant cast iron. Both materials possess excellent wear resistance and high-temperature resistance, making them perfectly suited for high-temperature and high-wear working environments such as steel mills. High-manganese steel undergoes work hardening upon impact, significantly increasing its surface hardness and effectively resisting scratches and wear from sharp objects. Wear-resistant cast iron, on the other hand, possesses high hardness and good toughness, maintaining stable mechanical properties even at high temperatures. It is not prone to softening or deformation due to high temperatures and can withstand the high-temperature burning of splashed molten iron for extended periods. Each wear-resistant plate 3 has at least three protective protrusions on its exterior, ensuring that each plate has sufficient protective points. This prevents insufficient protection due to an inadequate number of protrusions. Three or more protrusions can form a triangular or multi-point support structure, further enhancing its resistance to external impacts and ensuring the protective effect of the wear-resistant plate 3 under complex working conditions.

[0025] The usage method of this embodiment is as follows: In steel plants, to prevent molten iron from scalding the tires of engineering vehicles, the tires can be pre-installed inside the first protective shell 1 and the second protective shell 7 and then inflated. The first protective shell 1 and the second protective shell 7 are then fixed by the wear-resistant plate 3. The first protective shell 1 and the second protective shell 7, along with the tires, are then installed on the engineering vehicle. The tires are protected by the wear-resistant plate 3, the first protective shell 1, and the second protective shell 7.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
