Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a cut-resistant solid tire. Background Technology

[0002] Solid tires, due to their characteristics of being "airless, puncture-resistant, and having high load-bearing capacity," have become core consumables in industrial machinery and special operation scenarios. They are widely used in complex environments such as mining machinery (loaders, mining forklifts), port terminals (container stackers), waste treatment plants (garbage trucks), and construction sites (road rollers, crawler cranes). In these scenarios, tires frequently come into contact with sharp foreign objects (such as mine gravel, metal scrap, and construction waste fragments) and withstand high-intensity crushing (single tire load can reach 5-20 tons). Ordinary solid tires are prone to tread damage due to cutting and tearing, with an average service life of only 300-500 working hours, requiring frequent replacement.

[0003] Traditional rubber tires are mostly pneumatic. Pneumatic rubber tires cannot withstand the cutting of sharp objects. In complex working environments, they are easily punctured by sharp objects, causing difficulties in vehicle movement and affecting the normal use of the vehicle. At the same time, existing rubber tires are prone to deformation under stress during use, and their load-bearing capacity for the vehicle is limited, and they are not stable enough when rolling.

A fixed sleeve is fixedly fitted on the outer surface of the fixed shaft. Multiple tension sleeves are fixedly connected to the outer surface of the fixed sleeve. The multiple tension sleeves are arranged in a circular array. A tension spring is fixedly connected to the inner wall of the tension sleeve. An air inlet hose is fixedly connected to the outer surface of the fixed sleeve and is located inside the tension sleeve. A sliding plate is fixedly connected to the end of the tension spring away from the tension sleeve. An air storage plate is fixedly connected to the side of the sliding plate away from the tension spring and extends to the outside of the tension sleeve.

[0006] As a preferred embodiment of the cut-resistant solid tire of this utility model, a protective sleeve is fixedly connected to the end of the inner wall of the tension sleeve away from the tension spring, and one side of the protective sleeve is detached from one side of the slide plate.

[0007] In a preferred embodiment of the cut-resistant solid tire of this utility model, the end of the air intake hose away from the fixing sleeve is connected to the air storage plate. The interior of the air storage plate is hollow. The fixing sleeve and the interior of the air storage plate are connected through the air intake hose. The outer surface of the air storage plate has multiple air outlets, and the air outlets are fitted to the inner sidewall of the protective sleeve. The outer surface of the sliding plate is slidably fitted to the inner wall of the tension sleeve. One end of the tension sleeve has a sliding groove. The air storage plate extends to the outside of the tension sleeve through the sliding groove, and the air storage plate is slidably connected to the tension sleeve through the sliding groove. The width of the two sides of the support sleeve is greater than the width of the air storage plate, and the outer surface of the support sleeve abuts against the inner wall of the reinforced steel ring.

[0008] As a preferred embodiment of the cut-resistant solid tire of this utility model, the solid tire body includes a solid inner tube fixedly fitted on the outer surface of a reinforced steel rim, a solid outer tire fixedly fitted on the outer surface of the solid inner tube, a metal ring fixedly fitted on the outer surface of the solid outer tire, a plurality of limiting posts fixedly fitted on the outer surface of the metal ring, and the plurality of limiting posts are arranged in a ring array, a metal mesh is interlaced on the outer surface of the limiting posts, and the inner wall of the metal mesh is in contact with the outer surface, the thickness of the metal mesh is the same as the length of the limiting posts, and a fireproof layer is fixedly fitted on the outer surface of the metal mesh.

[0009] In a preferred embodiment of the cut-resistant solid tire of this utility model, the fireproof layer includes a first fireproof ring fixedly sleeved on the outer surface of the metal mesh, a rubber filling layer fixedly sleeved on the outer surface of the first fireproof ring, a fireproof film fixedly sleeved on the outer surface of the rubber filling layer, and a second fireproof ring fixedly sleeved on the outer surface of the fireproof film.

[0010] In a preferred embodiment of the cut-resistant solid tire of this utility model, the first fireproof ring, the rubber filling layer, the fireproof film, and the second fireproof ring are fixedly connected by adhesive pressing, and both the first fireproof ring and the second fireproof ring are made of neoprene rubber.

[0011] (III) Beneficial Effects This invention provides a cut-resistant solid tire. It has the following beneficial effects: 1. The support sleeve supports the inner wall of the reinforced steel ring. When the support assembly rotates, it drives the fixed sleeve to rotate, which in turn drives multiple tension sleeves to rotate. Due to the centrifugal force of rotation, the gas storage plate is thrown out, thereby extending the support sleeve to the inner wall of the reinforced steel ring, thus supporting the inner wall of the reinforced steel ring. The fixed shaft is filled with nitrogen. Since the fixed shaft and the fixed sleeve are connected, the nitrogen inside the fixed shaft flows into the fixed sleeve and then into the gas storage plate through the air inlet hose. When the fixed shaft rotates, the gas storage plate is thrown out by centrifugal force, causing the air outlet on the outside of the gas storage plate to be thrown out, thus allowing the nitrogen inside the gas storage plate to flow out and into the support sleeve, inflating and expanding the support sleeve.

[0012] 2. When the tire is cut by a sharp object, it is first intercepted by the metal mesh, and then isolated and resisted by the limiting post and metal ring, effectively preventing the sharp object from continuing to puncture the tire and fully ensuring the safety of tire use. Through the fireproof layer, the tire has good physical and mechanical properties such as heat resistance, fire resistance and corrosion resistance. In addition, the fireproof isolation of the rubber filling layer and fireproof film can effectively avoid the risk of the tire being ignited and causing the vehicle to burn.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example 1 Reference Figure 1 , Figure 2 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a cut-resistant solid tire, including a solid tire body 1. The outer surface of the solid tire body 1 is provided with anti-slip texture 101 for preventing slippage. A reinforcing steel ring 3 is fixedly connected to the inner wall of the solid tire body 1. The outer surface of the reinforcing steel ring 3 is fixedly provided with mounting holes 4. A support component 5 is provided inside the reinforcing steel ring 3. The support assembly 5 includes a fixed shaft 501 fixedly connected to the inner wall of the reinforcing steel ring 3. A fixed sleeve 502 is fixedly sleeved on the outer surface of the fixed shaft 501. A plurality of tension sleeves 503 are fixedly connected to the outer surface of the fixed sleeve 502. The plurality of tension sleeves 503 are arranged in a ring array. A tension spring 504 is fixedly connected to the inner wall of the tension sleeve 503. An air inlet hose 505 is fixedly connected to the outer surface of the fixed sleeve 502 and is located inside the tension sleeve 503. A sliding plate 506 is fixedly connected to the end of the tension spring 504 away from the tension sleeve 503. An air storage plate 507 is fixedly connected to the side of the sliding plate 506 away from the tension spring 504 and extends to the outside of the tension sleeve 503. A support sleeve 509 is fixedly connected to the end of the air storage plate 507 away from the sliding plate 506.

[0021] Specifically, a protective sleeve 508 is fixedly connected to the inner wall of the tension sleeve 503 away from the tension spring 504. One side of the protective sleeve 508 is detached from one side of the slide plate 506. The end of the air inlet hose 505 away from the fixed sleeve 502 is connected to the air storage plate 507. The interior of the air storage plate 507 is hollow. The fixed sleeve 502 and the interior of the air storage plate 507 are connected through the air inlet hose 505. The outer surface of the air storage plate 507 has multiple air outlets. The inner wall of the protective sleeve 508 is fitted to the outer surface of the sliding plate 506 and the inner wall of the tension sleeve 503 are slidably fitted to each other. A sliding groove is provided at one end of the tension sleeve 503. The air storage plate 507 extends to the outside of the tension sleeve 503 through the sliding groove and is slidably connected to the tension sleeve 503 through the sliding groove. The width of the two sides of the support sleeve 509 is greater than the width of the air storage plate 507. The outer surface of the support sleeve 509 abuts against the inner wall of the reinforcing steel ring 3.

[0022] Furthermore, based on the function of the support sleeve 509, it can support the inner wall of the reinforced steel ring 3. When the support assembly 5 rotates, it drives the fixed sleeve 502 to rotate. When the fixed sleeve 502 rotates, it drives multiple tension sleeves 503 to rotate. Based on the centrifugal force of rotation, the gas storage plate 507 is rotated and thrown out, thereby extending the support sleeve 509 to the inner wall of the reinforced steel ring 3, so that the support sleeve 509 supports the inner wall of the reinforced steel ring 3. The interior of the fixed shaft 501 is filled with nitrogen. Nitrogen gas flows from the fixed shaft 501 into the fixed sleeve 502, and then through the air inlet hose 505 into the gas storage plate 507. When the fixed shaft 501 rotates, the gas storage plate 507 is thrown out by centrifugal force, causing the air outlet on the outside of the gas storage plate 507 to be thrown out, thereby allowing the nitrogen gas inside the gas storage plate 507 to flow out and into the support sleeve 509, inflating and expanding the support sleeve 509.

[0023] Example 2 Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0024] The solid tire body 1 includes a solid inner tube 102 fixedly fitted on the outer surface of the reinforced steel rim 3. A solid outer tire 103 is fixedly fitted on the outer surface of the solid inner tube 102. A metal ring plate 104 is fixedly fitted on the outer surface of the solid outer tire 103. A plurality of limiting posts 105 are fixedly fitted on the outer surface of the metal ring plate 104, and the plurality of limiting posts 105 are arranged in a ring array. A metal mesh 106 is interspersed on the outer surface of the limiting posts 105, and the inner wall of the metal mesh 106 is in contact with the outer surface of the 104. The thickness of the metal mesh 106 is the same as the length of the limiting posts 105, and a fireproof layer 107 is fixedly fitted on the outer surface of the metal mesh 106.

[0025] Specifically, the fireproof layer 107 includes a first fireproof ring 1071 fixedly sleeved on the outer surface of the metal mesh 106, a rubber filling layer 1072 fixedly sleeved on the outer surface of the first fireproof ring 1071, a fireproof membrane 1073 fixedly sleeved on the outer surface of the rubber filling layer 1072, and a second fireproof ring 1074 fixedly sleeved on the outer surface of the fireproof membrane 1073. The first fireproof ring 1071, the rubber filling layer 1072, the fireproof membrane 1073, and the second fireproof ring 1074 are fixedly connected by adhesive pressing, and both the first fireproof ring 1071 and the second fireproof ring 1074 are made of neoprene rubber.

[0026] Furthermore, when the tire is cut by a sharp object, it is first intercepted by the metal mesh 106, and then isolated and resisted by the limiting post 105 and the metal ring 104, effectively preventing the sharp object from continuing to puncture the tire and fully ensuring the safety of tire use. Through the fireproof layer 107, the tire has good physical and mechanical properties such as heat resistance, flame resistance and corrosion resistance. In addition, the fireproof isolation of the rubber filling layer 1072 and the fireproof film 1073 can effectively avoid the risk of the tire being ignited and causing the vehicle to burn.

[0027] Working principle: During use, when the tire encounters a sharp object while the vehicle is in motion, the object cuts through the outermost fireproof layer 107. If it continues to penetrate, it is intercepted by the metal mesh 106, and then further protected by the limiting post 105 and the metal ring 104, effectively preventing the object from continuing to puncture the tire. When the vehicle is parked and exposed to high temperatures or sparks, the first fireproof ring 1071 and the second fireproof ring 1074 of the fireproof layer 107 provide fireproof and high-temperature resistant isolation. Combined with the rubber filler layer 1072 and the fireproof membrane 1073, their excellent physical and mechanical properties, such as heat resistance, flame retardancy, and corrosion resistance, ensure that the tire is not ignited and thus does not burn the vehicle. The support sleeve 509 supports the inner wall of the reinforced steel ring 3. When the support component 5 rotates, it drives the fixed sleeve 502 to rotate, and when the fixed sleeve 502 rotates, it drives multiple tension sleeves 503 to rotate. Based on the centrifugal force of rotation, the air storage plate 507 is rotated and thrown out, thereby extending the support sleeve 509 to the inner wall of the reinforcing steel ring 3. The support sleeve 509 supports the inner wall of the reinforcing steel ring 3. The fixed shaft 501 is filled with nitrogen. Since the fixed shaft 501 and the fixed sleeve 502 are connected, the nitrogen inside the fixed shaft 501 flows into the fixed sleeve 502, and then flows into the air storage plate 507 through the air intake hose 505. When the fixed shaft 501 rotates, the air storage plate 507 is thrown out by the centrifugal force, causing the air outlet on the outside of the air storage plate 507 to be thrown out, thereby causing the nitrogen inside the air storage plate 507 to flow out and into the support sleeve 509, inflating and expanding the support sleeve 509, thereby supporting the reinforcing steel ring 3 and preventing the tire from deforming under stress during use.
