Description

Explosion-proof polyurethane tire for engineering vehicle Technical Field The utility model relates to the field of tires, in particular to an explosion-proof polyurethane tire for engineering vehicles. Background In the field of engineering construction, engineering vehicles play a vital role, and they often need to operate in complex and severe environments, such as mines, construction sites, deserts, and the like. These environments place extremely high demands on the performance of the tires, which are the only components of the work vehicle in contact with the ground, which directly affect the running safety, working efficiency and use costs of the vehicle. The engineering vehicle has complex operation environment and bad road surface condition, and has sharp stones, metal fragments and other impurities. Conventional tires are extremely prone to puncture or laceration when encountering such sharp objects, resulting in momentary tire pressure loss or even puncture. Once tire burst occurs, the vehicle can lose control, serious safety accidents are caused, engineering interruption can be caused, construction progress is affected, and maintenance cost is increased. Secondly, engineering vehicles often carry heavy loads and the tires need to withstand significant pressure and impact forces during travel. The structural design of the traditional tire often has difficulty in meeting the use requirement of high strength, and the problems of deformation, cracking and the like of the tire body easily occur after the tire is subjected to heavy load and impact for a long time, so that the service life of the tire is shortened, and the frequency and cost for replacing the tire are increased. Disclosure of utility model The utility model aims to provide an explosion-proof polyurethane tire for an engineering vehicle, which solves the problems of poor explosion-proof performance and insufficient structural strength of the existing engineering vehicle tire. The technical scheme is that the explosion-proof polyurethane tire for the engineering vehicle comprises a hub and a tire body, wherein the tire body is coated on the outer side of the hub, a plurality of metal rings are equidistantly arranged in the tire body, the metal rings are sleeved on the outer side of the hub, a reinforcing sleeve is arranged in the tire body, and the reinforcing sleeve is arranged on the outer side of the metal rings in a spiral winding mode. Preferably, the carcass is integrally formed on the outer side of the metal ring and the reinforcing sleeve through a casting process, and the integrally formed structure ensures that all parts of the tire are tightly connected, so that the integrity is good. Preferably, the outer side surface of the tire body is provided with anti-skid patterns, so that the anti-skid performance of the tire is enhanced, and the ground grabbing force of the engineering vehicle under different road conditions is improved. Preferably, a buffer cushion is arranged between the wheel hub and the metal ring, so that the buffer and shock absorption effects are achieved, and vibration and impact force applied to the tire and the wheel hub in the running process are reduced. Preferably, grooves in annular arrays are formed in the outer walls of two sides of the tire body, the width of the notch of each groove gradually widens from one side close to the hub to the outer ring direction of the tire body, and the gradual change type groove structure is formed and can bear pressure better, so that the structural stability of the tire body is maintained. Preferably, the cross section of the metal ring is circular, and the stress can be uniformly dispersed to reduce deformation and damage of a local area of the metal ring, so that the stability and reliability of the metal ring are improved, and the service life of the tire is prolonged. Preferably, the depth of the groove gradually becomes shallow from the outer circumference to the inner circumference of the tire body, so that the strength and the impact resistance of the tire sidewall part are improved while the drainage and mud discharge performances of the tire are ensured. Compared with the prior art, the utility model has the following advantages: 1. According to the utility model, the plurality of metal rings are equidistantly arranged in the tire body, and the reinforcing sleeves are arranged on the outer sides of the metal rings in a spiral winding manner, so that the overall strength and the shock resistance of the tire are enhanced, the damage of the tire caused by puncture, collision and the like of a sharp object can be effectively resisted, the risk of tire burst under severe working conditions is obviously reduced, and the running safety of an engineering vehicle is ensured. 2. The reinforcing sleeve is arranged on the outer side of the metal ring in a spiral winding mode, so that the connection between the tire body and the metal ring is tighter and firmer, the tire
