Description

Technical Field

[0001] This utility model relates to the field of vehicle tire protection technology, specifically a puncture-proof protective cover for tires of open-pit mining vehicles. Background Technology

[0002] Open-pit mines operate in extremely harsh environments, with the work area littered with sharp rocks, rubble, metal scrap, and other debris generated from blasting and excavation. These objects are hard and have sharp edges, making tires highly susceptible to punctures and cuts when in contact with the ground. Mining transport vehicles, excavators, loaders, and other engineering vehicles have large, heavy-duty tires, resulting in high costs for purchasing and replacing individual tires. A puncture can lead to anything from minor issues like tire leaks and insufficient tire pressure, affecting vehicle performance and increasing fuel consumption, to more serious incidents like tire blowouts, endangering driver lives, interrupting operations, and delaying mine production.

[0003] Currently, to reduce the risk of tire punctures, efforts are being made to clean the work area, removing sharp rocks, metal scrap, and other debris that could puncture tires. Thicker tires are being used, or existing tires are being reinforced. However, open-pit mines have complex conditions, with sharp rocks and metal scrap constantly being generated. Cleaning work must be ongoing, consuming significant manpower, resources, and time. Furthermore, complete cleaning of the work area is difficult, especially on frequently used transport routes where new sharp debris continuously appears, limiting the effectiveness of the cleanup.

[0004] While thicker tires can improve puncture resistance to some extent, they are still made of rubber. Faced with the hard, sharp rocks and metal scrap in mines, they are still easily cut and punctured after prolonged contact, limiting the improvement in puncture resistance. To address these issues, the applicant designed a puncture-resistant protective cover for open-pit mine vehicle tires. Utility Model Content

[0005] The purpose of this utility model is to provide a puncture-proof protective cover for open-pit mine vehicle tires, which aims to improve the problem that the tires of existing open-pit mine vehicles are easily punctured by sharp objects, resulting in tire damage, operation interruption, major safety hazards and high maintenance costs.

[0006] This utility model is implemented as follows:

[0007] A puncture-resistant protective cover for open-pit mining vehicle tires includes an annular belt whose inner diameter is adapted to the outer diameter of the vehicle tire. The annular belt is made of rubber material. The annular belt includes a tread portion and a shoulder portion, which respectively wrap around the tread and shoulder of the vehicle tire. A protrusion structure is arranged around the outer wall of the tread portion. A reinforcing protective layer is provided inside the annular belt, which completely covers the tread portion.

[0008] Furthermore, the inner wall of the tread surface is provided with anti-slip texture, and / or the rubber surface is roughened to form an anti-slip layer. The roughening treatment method includes, but is not limited to, sandblasting, chemical etching or mold pressing.

[0009] Furthermore, the reinforced protective layer includes a first reinforced protective layer and a second reinforced protective layer, which are sequentially arranged at a certain distance along the thickness direction of the annular strip.

[0010] Furthermore, the distance between the first and second reinforced protective layers is 5-10 mm.

[0011] Furthermore, the first and second reinforcing protective layers are made of aramid fibers, ultra-high molecular weight polyethylene fibers, or steel wire mesh.

[0012] Furthermore, both the first and second reinforcing protective layers are made of wire mesh, and the mesh openings of the two layers are staggered.

[0013] Furthermore, a splicing seam is provided on the annular belt, and the splicing seam is glued together.

[0014] Furthermore, the annular belt has a frosted surface or a textured structure on the cross-section at the splice seam.

[0015] Furthermore, a connecting block is provided on each side of the splice seam on the tire shoulder, one side wall of the connecting block is aligned with the splice seam, and a connecting groove is provided on the other side wall of the connecting block.

[0016] Furthermore, when the two connecting blocks on both sides of the splice seam are aligned, the connecting grooves of the two connecting blocks form an annular groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a rubber ring belt adapted to the tire size to disperse the impact force of sharp objects and enhance grip by using the convex structure on the outer wall of the tread. By strengthening the protective layer, the puncture resistance is significantly improved, thus effectively preventing vehicle tires from being punctured by sharp objects.

[0019] 2. The first and second reinforced protective layers of this utility model are set at certain intervals. They are made of high-performance materials such as aramid fiber, ultra-high molecular weight polyethylene fiber or steel wire mesh with staggered mesh, forming multiple physical barriers to block sharp objects from penetrating, thus further improving the protective capability of this utility model.

[0020] 3. The annular belt of this utility model has a connecting block on each side of the splice seam on the shoulder. The side wall of the connecting block is provided with a connecting groove. Rigid fastening components such as steel wire and pipe clamp can be installed in the connecting groove. The connection stability at the splice seam is further strengthened by radial tightening force to prevent the glued part from loosening under heavy load or severe vibration.

[0027] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0028] Example 1

[0029] like Figure 1 and Figure 2As shown, a puncture-resistant protective cover for open-pit mining vehicle tires includes an annular belt whose inner diameter matches the outer diameter of the vehicle tire. The annular belt is made of rubber. The annular belt includes a tread portion 1 and a shoulder portion 2, which respectively wrap around the tread and shoulder of the vehicle tire. The inner wall of the tread portion 1 is provided with anti-slip treads 6, and / or the rubber surface is roughened by sandblasting to form an anti-slip layer. By providing anti-slip treads 6 or an anti-slip layer, the friction between the inner wall of the tread portion 1 and the tire tread can be increased, effectively preventing the annular belt from slipping or misaligning relative to the tire during vehicle operation. A protrusion structure 3 is arranged around the outer wall of the tread portion 1. This protrusion structure 3 can reduce the probability of the tread portion 1 being directly punctured by dispersing the impact force of sharp objects, while simultaneously enhancing grip with the mining ground to improve driving stability.

[0030] like Figure 3 As shown, a reinforcing protective layer is provided inside the annular belt, completely covering the tread area 1. The reinforcing protective layer includes a first reinforcing protective layer 4 and a second reinforcing protective layer 5, which are arranged sequentially at 5mm intervals along the thickness direction of the annular belt. The first reinforcing protective layer 4 and the second reinforcing protective layer 5 are made of aramid fiber or ultra-high molecular weight polyethylene fiber, respectively. Aramid fiber, with its rigid molecular chain structure and ultra-high tensile strength, can disperse the piercing force of sharp objects through strong interlocking between fibers. Its excellent toughness effectively resists cutting and tearing, physically preventing punctures. Ultra-high molecular weight polyethylene fiber achieves high strength through a highly crystalline structure formed by ultra-long molecular chains. Simultaneously, the high toughness of the fiber can buffer impact force through deformation, preventing damage to the protective layer due to excessive local stress. The dual protective structure uses the high strength characteristics of the fiber materials to block punctures by sharp objects, and the spaced layered structure further absorbs impact energy through buffering to improve puncture resistance. Both high-performance fiber materials possess good flexibility and wear resistance, can deform synchronously with the annular belt, and are not prone to breakage or failure after long-term use.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, a splicing seam 7 is provided on the annular belt to facilitate its installation on the vehicle tire. The splicing seam 7 is glued together. The annular belt has a frosted surface or textured structure on the cross-section at the splicing seam 7 to increase the roughness and contact area of ​​the adhesive surface, enhancing the adhesive strength at the splicing seam and preventing delamination and cracking under the bumps and impacts of mining vehicles. A connecting block 8 is provided on each side of the tire shoulder 2, located on either side of the splicing seam 7. One sidewall of the connecting block 8 is aligned with the splicing seam 7, and the other sidewall of the connecting block 8 has a connecting groove 9. When the two connecting blocks 8 on both sides of the splicing seam 7 are aligned, the connecting grooves 9 of the two connecting blocks 8 form an annular groove. Rigid fastening components such as steel wires or pipe clamps can be installed in the annular groove to further strengthen the connection stability at the splicing seam through radial tightening force, preventing loosening of the adhesive joint under heavy loads or severe vibrations.

[0032] Example 2

[0033] like Figure 1 and Figure 2 As shown, a puncture-resistant protective cover for open-pit mining vehicle tires includes an annular belt whose inner diameter matches the outer diameter of the vehicle tire. The annular belt is made of rubber. The annular belt includes a tread portion 1 and a shoulder portion 2, which respectively wrap around the tread and shoulder of the vehicle tire. The inner wall of the tread portion 1 is provided with anti-slip treads 6, and / or the rubber surface is roughened by chemical etching to form an anti-slip layer. By providing anti-slip treads 6 or an anti-slip layer, the friction between the inner wall of the tread portion 1 and the tire tread can be increased, effectively preventing the annular belt from slipping or misaligning relative to the tire during vehicle operation. A protrusion structure 3 is arranged around the outer wall of the tread portion 1. This protrusion structure 3 can reduce the probability of the tread portion 1 being directly punctured by dispersing the impact force of sharp objects, while simultaneously enhancing grip with the mining ground to improve driving stability.

[0034] like Figure 3 As shown, a reinforcing protective layer is provided inside the annular belt, completely covering the tread area 1. The reinforcing protective layer includes a first reinforcing protective layer 4 and a second reinforcing protective layer 5, which are arranged sequentially at 8mm intervals along the thickness direction of the annular belt. The first reinforcing protective layer 4 and the second reinforcing protective layer 5 are made of aramid fiber and steel wire mesh, respectively. The high toughness of the aramid fiber can buffer the puncture impact, while the rigid skeleton of the steel wire mesh can physically block the penetration of sharp objects. Together, they form a double puncture-resistant barrier of "buffering + blocking".

[0035] like Figure 1 , Figure 2 and Figure 4As shown, a splicing seam 7 is provided on the annular belt to facilitate its installation on the vehicle tire. The splicing seam 7 is glued together. The annular belt has a frosted surface or textured structure on the cross-section at the splicing seam 7 to increase the roughness and contact area of ​​the adhesive surface, enhancing the adhesive strength at the splicing seam and preventing delamination and cracking under the bumps and impacts of mining vehicles. A connecting block 8 is provided on each side of the tire shoulder 2, located on either side of the splicing seam 7. One sidewall of the connecting block 8 is aligned with the splicing seam 7, and the other sidewall of the connecting block 8 has a connecting groove 9. When the two connecting blocks 8 on both sides of the splicing seam 7 are aligned, the connecting grooves 9 of the two connecting blocks 8 form an annular groove. Rigid fastening components such as steel wires or pipe clamps can be installed in the annular groove to further strengthen the connection stability at the splicing seam through radial tightening force, preventing loosening of the adhesive joint under heavy loads or severe vibrations.

[0036] Example 3

[0037] like Figure 1 and Figure 2 As shown, a puncture-resistant protective cover for open-pit mining vehicle tires includes an annular belt whose inner diameter is adapted to the outer diameter of the vehicle tire. The annular belt is made of rubber. The annular belt includes a tread portion 1 and a shoulder portion 2, which respectively wrap around the tread and shoulder of the vehicle tire. The inner wall of the tread portion 1 is provided with anti-slip treads 6, and / or the rubber surface is roughened by molding to form an anti-slip layer. By providing anti-slip treads 6 or an anti-slip layer, the friction between the inner wall of the tread portion 1 and the tire tread can be increased, effectively preventing the annular belt from slipping or misaligning relative to the tire during vehicle operation. A protrusion structure 3 is arranged around the outer wall of the tread portion 1. This protrusion structure 3 can reduce the probability of the tread portion 1 being directly punctured by dispersing the impact force of sharp objects, while simultaneously enhancing grip with the mining ground to improve driving stability.

[0038] like Figure 3 As shown, a reinforcing protective layer is provided inside the annular belt, completely covering the tread portion 1. The reinforcing protective layer includes a first reinforcing protective layer 4 and a second reinforcing protective layer 5, which are arranged sequentially at 10mm intervals along the thickness direction of the annular belt. Both the first and second reinforcing protective layers 4 and 5 are made of wire mesh, and their mesh openings are staggered, forming an interlaced reinforcement structure. This prevents sharp objects from directly penetrating the two protective layers through a single mesh opening, significantly improving the puncture resistance of the tread portion.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, a splicing seam 7 is provided on the annular belt to facilitate its installation on the vehicle tire. The splicing seam 7 is glued together. The annular belt has a frosted surface or textured structure on the cross-section at the splicing seam 7 to increase the roughness and contact area of ​​the adhesive surface, enhancing the adhesive strength at the splicing seam and preventing delamination and cracking under the bumps and impacts of mining vehicles. A connecting block 8 is provided on each side of the tire shoulder 2, located on either side of the splicing seam 7. One sidewall of the connecting block 8 is aligned with the splicing seam 7, and the other sidewall of the connecting block 8 has a connecting groove 9. When the two connecting blocks 8 on both sides of the splicing seam 7 are aligned, the connecting grooves 9 of the two connecting blocks 8 form an annular groove. Rigid fastening components such as steel wires or pipe clamps can be installed in the annular groove to further strengthen the connection stability at the splicing seam through radial tightening force, preventing loosening of the adhesive joint under heavy loads or severe vibrations.

[0040] In summary, this invention, by setting a rubber annular belt adapted to the tire size, utilizes the protrusion structure 3 on the outer wall of the tread 1 to disperse the impact force of sharp objects and enhance grip, and significantly improves puncture resistance through reinforced protective layers, thus effectively preventing vehicle tires from being punctured by sharp objects. The reinforced protective layers of this invention include a first reinforced protective layer 4 and a second reinforced protective layer 5, positioned at certain intervals. Both are made of high-performance materials such as aramid fiber, ultra-high molecular weight polyethylene fiber, or steel wire mesh with staggered mesh, forming multiple physical barriers to block penetration by sharp objects, further improving the protective capability of this invention. On the tire shoulder 2 of the annular belt, a connecting block 8 is provided on each side of the splice seam 7. The sidewall of the connecting block 8 is provided with a connecting groove 9, in which rigid fastening components such as steel wire and pipe clamps can be installed. Radial tightening force further strengthens the connection stability at the splice seam, preventing loosening of the adhesive joint under heavy loads or severe vibrations.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
