Description

Technical Field

[0001] The utility model relates to the technical field of mine vehicle tires, and particularly relates to a new air system non-pneumatic explosion-proof tire. Background Technique

[0002] The main reasons for the explosion of mine vehicle tires are as follows:

[0003] 1. Tire air leakage: When the tire is punctured by an iron nail or other sharp object and the tire is not punctured temporarily, the tire will have an air leakage phenomenon, which will cause a blowout;

[0004] 2. Excessive tire air pressure: Due to the high-speed driving of the vehicle, the tire temperature rises, the air pressure increases accordingly, the tire deforms, the elasticity of the tire body decreases, and the dynamic load received by the vehicle also increases. If it encounters an impact, internal cracks or a blowout will occur. This is also the reason why blowout accidents occur concentratedly in summer;

[0005] 3. Insufficient tire air pressure: When the vehicle is driving at high speed (speed exceeds 120KM / H), insufficient tire air pressure is likely to cause "harmonic vibration" of the tire body, thus triggering a huge resonant force. If the tire is not strong enough or already has "damage", it is prone to a blowout. Moreover, insufficient air pressure increases the sinking amount of the tire, and it is easy to cause the tire wall to touch the ground when turning sharply. The tire wall is the weakest part of the tire, and the tire wall touching the ground will also cause a blowout;

[0006] The tire is "working with problems": After long-term use, the tire is severely worn, there is no tread on the crown (or the tread is too low), the tire wall becomes thin, and it has become what people often call a "bald tire" or there are uneven "weak links". It will blow out because it cannot withstand the high pressure and high temperature of high-speed driving.

[0007] During the mine operation process, when the tire explodes, it will cause major accidents of casualties.

[0008] In view of this, we propose a new air system non-pneumatic explosion-proof tire. Content of the Utility Model

[0009] In order to make up for the above deficiencies, the utility model provides a new air system non-pneumatic explosion-proof tire.

[0010] The technical solution of the utility model is: including a non-pneumatic explosion-proof tire body, characterized in that: the non-pneumatic explosion-proof tire body includes a base rubber and a shock-absorbing rubber part. A group of circumferential rubber tubes are arranged in parallel in the inner cavities of the base rubber and the shock-absorbing rubber part. Four-way joints are equidistantly arranged on the circumferential rubber tubes. Horizontal rubber tubes are respectively arranged on the two transverse sides of the four-way joint. One side of the horizontal rubber tube is connected to a group of circumferential rubber tubes arranged in parallel, and the other side of the horizontal rubber tube extends to the side of the non-pneumatic explosion-proof tire body and is connected to an external air bladder, forming a new air system with gas circulation.

[0011] As a preferred technical solution, a hub is provided at the center of the non-pneumatic explosion-proof tire body.

[0012] As a preferred technical solution, a flame-retardant rubber is disposed around the hub.

[0013] As a preferred technical solution, multiple steel wires are wound around the surface of the flame-retardant rubber.

[0014] As a preferred technical solution, the base rubber is disposed around the flame-retardant rubber.

[0015] As a preferred technical solution, a tread rubber is disposed around the shock-absorbing rubber.

[0016] As a preferred technical solution, the shock-absorbing rubber is disposed around the base rubber.

[0017] As a preferred technical solution, the surrounding rubber tubes are connected end to end through four-way joints to form a ring.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] By providing a group of parallel surrounding rubber tubes in the inner cavities of the base rubber and the shock-absorbing rubber, and the surrounding rubber tubes are connected end to end through four-way joints to form a ring. On the four-way joints, a transverse rubber tube is used to not only realize the connection of the group of parallel surrounding rubber tubes, but also extend to the side of the non-pneumatic explosion-proof tire body to be connected with an external air bladder, forming a gas circulation system. With the setting of this fresh air system, during the vulcanization process of the non-pneumatic explosion-proof tire body, steam is injected through the surrounding rubber tubes and the transverse rubber tubes, so that the vulcanization time of the non-pneumatic explosion-proof tire body is shortened by half, and the quality of the tire product is also guaranteed. At the same time, it solves the problem that during the vehicle transportation and driving of the finished tire, heat is generated due to the fatigue of the tire and the friction with the ground. The internal temperature of the tire is discharged through the surrounding rubber tubes, transverse rubber tubes and air bladder inside the tire, and cold air outside enters, forming an internal and external circulation and guiding fresh air system (breathing) non-pneumatic explosion-proof tire.

[0028] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0029] A fresh air system non-pneumatic explosion-proof tire includes a non-pneumatic explosion-proof tire body 1.

[0030] The non-pneumatic explosion-proof tire body 1 includes a base rubber 2 and a shock-absorbing rubber part 3.

[0031] A group of surrounding rubber tubes 401 are arranged in parallel in the inner cavities of the base rubber 2 and the shock-absorbing part rubber 3. Four-way joints 402 are arranged at equal intervals on the surrounding rubber tubes 401. Transverse rubber tubes 403 are respectively arranged on the two transverse sides of the four-way joints 402. One side of the transverse rubber tube 403 is connected to a group of surrounding rubber tubes 401 arranged in parallel, and the other side of the transverse rubber tube 403 extends to the side of the non-pneumatic explosion-proof tire body 1 and is connected to an externally connected air bladder, forming a fresh air system 4 with gas circulation.

[0032] In this embodiment, the surrounding rubber tubes 401 are connected end to end through the four-way joints 402 to form a ring.

[0033] It is worth further explaining that the four-way joints 402 are longitudinally inserted into the surrounding rubber tubes 401 and transversely inserted into the transverse rubber tubes 403.

[0034] It is worth further explaining that on the one hand, the transverse rubber tube 403 realizes the connection of a group of adjacent and parallel surrounding rubber tubes 401, and on the other hand, it extends to the side of the non-pneumatic explosion-proof tire body 1 and is connected to an externally connected air bladder, forming a fresh air system 4 with gas circulation.

[0035] In this embodiment, a hub 5 is provided at the center of the non-pneumatic explosion-proof tire body 1.

[0036] In this embodiment, a flame-retardant rubber 6 is arranged around the hub 5.

[0037] In this embodiment, multiple steel wires 601 are wound on the surface of the flame-retardant rubber 6.

[0038] In this embodiment, the base rubber 2 is arranged around the flame-retardant rubber 6.

[0039] In this embodiment, a tread rubber 7 is arranged around the shock-absorbing part rubber 3.

[0040] In this embodiment, the shock-absorbing part rubber 3 is arranged around the base rubber 2.

[0041] It is worth further explaining that the structure of the non-pneumatic explosion-proof tire body 1 from the inside to the outside is successively the hub 5, the flame-retardant rubber 6, the base rubber 2, the shock-absorbing part rubber 3, and the tread rubber 7.

[0042] When the non-pneumatic explosion-proof tire body 1 of the present utility model is in use, the surrounding rubber tubes 401 are connected end to end through the four-way joints 402 to form a ring. The four-way joints 402 are transversely inserted into the transverse rubber tubes 403. On the one hand, the transverse rubber tube 403 realizes the connection of a group of adjacent and parallel surrounding rubber tubes 401, and on the other hand, it extends to the side of the non-pneumatic explosion-proof tire body 1 and is connected to an externally connected air bladder, forming a fresh air system 4 with gas circulation.

[0043] During the vulcanization process of the non-pneumatic explosion-proof tire body 1, steam is injected through the circumferential rubber tube 402 and the transverse rubber tube 403. The steam flows alternately in the circumferential rubber tube 401, the four-way joint 402, and the transverse rubber tube 403. As a result, the vulcanization time of the non-pneumatic explosion-proof tire body 1 is shortened by half, and the quality of the tire product is also ensured. At the same time, it solves the problem that during the vehicle transportation and driving of the finished tire, heat is generated due to tire fatigue and ground friction. The internal temperature of the tire is discharged through the circumferential rubber pipeline 402, the transverse rubber pipeline 403, and the air breather inside the tire cavity, and cold air from the outside enters, forming an internal and external circulation and guiding fresh air system (breathing) non-pneumatic explosion-proof tire.
