Description

Technical Field

[0001] This utility model relates to the field of solid tire technology, specifically a polyurethane solid tire. Background Technology

[0002] Solid tires are a type of polyurethane solid tire that is the counterpart to pneumatic tires (hollow tires). Their carcass is solid, without cords as a skeleton, and they do not need to be inflated. Therefore, they do not need an inner tube or airtight layer. Solid tires are only used for high-load vehicles or machinery that travel at low speeds, as well as for machinery that is stationary.

[0003] After prolonged use, the anti-slip blocks and grooves on the surface of conventional solid tires will wear off, resulting in reduced vehicle grip and requiring the entire tire to be replaced, which increases maintenance costs. Moreover, regardless of road conditions, the anti-slip blocks on the tire surface will always be in contact with the ground, shortening the tire's lifespan. Therefore, there is an urgent need for a polyurethane solid tire to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a polyurethane solid tire to solve the problem mentioned in the background art that, after long-term use, the anti-slip blocks and anti-skid grooves on the tire surface of conventional solid tires will be worn away, resulting in reduced vehicle grip and friction, requiring the entire tire body to be replaced, which increases maintenance costs. Moreover, regardless of the road conditions, the anti-slip blocks on the tire surface will always be in contact with the ground and rub against it, which shortens the tire's service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane solid tire, including a rim, a tire body mounted on the surface of the rim, anti-skid grooves formed on the surface of the tire body, an array of operating holes formed on the surface of the rim and the operating holes penetrating the rim, an array of guide grooves formed on the side surface of the rim and the guide grooves penetrating the side surface of the rim, a support ring provided on the surface of the rim, and connecting blocks welded in an array between the support ring and the rim; it also includes an adjustment assembly, the adjustment assembly being disposed on both sides of the rim for adjusting the friction between the tire body and the ground, and the adjustment assembly having an axisymmetric structure about the rim.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This utility model discloses a polyurethane solid tire with adjustment components on both sides of the rim. In the adjustment components, the friction strip can be adjusted in length on the surface of the tire body according to the specific usage conditions. When the friction strip protruding from the tire body is worn, it can be adjusted back to its original position. This design allows the solid tire to adjust the friction between the tire and the ground simply by adjusting and replacing the friction strip, which not only reduces the tire maintenance cost but also extends the tire's service life.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-7This utility model provides a polyurethane solid tire, including a rim 2, a tire body 4 mounted on the surface of the rim 2, anti-skid grooves 3 formed on the surface of the tire body 4, an array of operating holes 5 formed on the surface of the rim 2, the operating holes 5 penetrating the rim 2, an array of guide grooves 6 formed on the side of the rim 2, the guide grooves 6 penetrating the side of the rim 2, a support ring 9 formed on the surface of the rim 2, and connecting blocks 8 welded in an array between the support ring 9 and the rim 2; it also includes an adjustment component 1, which is disposed on both sides of the rim 2 to adjust the friction between the tire body 4 and the ground, and the adjustment component 1 has an axisymmetric structure about the rim 2;

[0018] Specifically, in the adjustment component 1, the friction strip 102 can be adjusted in length on the surface of the tire body 4 according to the specific usage conditions. When the friction strip 102 protruding from the tire body 4 is worn, it can be adjusted back to its original position. This design allows the solid tire to adjust the friction force between the tire and the ground simply by adjusting and replacing the friction strip 102, which not only reduces the tire maintenance cost but also extends the tire's service life. The anti-skid grooves 3 and the friction strip 102 on the surface of the tire body 4 are arranged alternately on the surface of the tire body 4, increasing the friction force between the solid tire and the ground.

[0019] Adjustment component 1 includes an elastic ring 101, the central axis of which coincides with the central axis of the rim 2;

[0020] Specifically, the elastic ring 101 is usually made of elastic materials such as steel plate. It not only has a certain expansion capability, but also can replace the replacement of the tire body 4 by replacing the elastic ring 101, which not only makes the operation simpler, but also reduces the replacement cost.

[0021] Friction strips 102 are evenly fixed on the side of the elastic ring 101, and the friction strips 102 are movably connected to the guide groove 6, and the friction strips 102 penetrate the support ring 9;

[0022] Specifically, with the support and guidance of the guide groove 6, the friction strip 102 can enter the movable groove 7 on the surface of the tire body 4 along the guide groove 6, which facilitates the adjustment of the friction strip 102;

[0023] The inner side of the elastic ring 101 is provided with adjusting bolts 103, and the adjusting bolts 103 pass through the elastic ring 101, and the adjusting bolts 103 are movably connected to the elastic ring 101, and the adjusting bolts 103 are threadedly connected to the support ring 9.

[0024] Specifically, by rotating the adjusting bolt 103, the elastic ring 101 can contract and expand to a certain extent with the support ring 9 as the support point;

[0025] The surface of the tire body 4 is provided with movable grooves 7, and the movable grooves 7 pass through the tire body 4 respectively, and the friction strip 102 is movably connected to the movable grooves 7.

[0026] Specifically, the friction strip 102 is fixed in position in the movable groove 7 under the support of the support ring 9;

[0027] The base material is made of composite polyurethane material;

[0028] Specifically, polyurethane material itself has excellent wear resistance, tear resistance, and aging resistance. Compared with traditional solid rubber tires or pneumatic tires, its durability is significantly improved. Polyurethane has a compact molecular structure and moderate surface hardness. Its wear rate on rough surfaces is much slower than that of rubber tires. Moreover, when faced with heavy objects running over it or minor impacts, polyurethane is not prone to cracks, bulges, or deformation. It can maintain structural integrity for a long time and reduce equipment downtime caused by tire damage.

[0029] Working principle: The elastic ring 101 is usually made of elastic materials such as steel plate. It not only has a certain expansion capacity, but also can replace the tire carcass 4 by replacing the elastic ring 101, which not only simplifies the operation, but also reduces the replacement cost. With the support and guidance of the guide groove 6, the friction strip 102 can enter the movable groove 7 on the surface of the tire carcass 4 along the guide groove 6, which facilitates the adjustment of the friction strip 102. By rotating the adjusting bolt 103, the elastic ring 101 can contract and expand to a certain extent with the support ring 9 as the support point. Under the support of the support ring 9, the position of the friction strip 102 in the movable groove 7 is fixed.

[0030] Polyurethane material itself has excellent wear resistance, tear resistance and aging resistance. Compared with traditional solid rubber tires or pneumatic tires, its durability is significantly improved. Polyurethane has a compact molecular structure and moderate surface hardness. Its wear rate on rough ground is much slower than that of rubber tires. Moreover, when faced with heavy objects running over it or minor impacts, polyurethane is not prone to cracks, bulges or deformation. It can maintain structural integrity for a long time and reduce equipment downtime caused by tire damage.

[0031] In the adjustment component 1, the friction strip 102 can be adjusted in length on the surface of the tire body 4 according to the specific usage conditions. When the friction strip 102 protruding from the tire body 4 is worn, it can be adjusted back to its original position. This design allows the solid tire to adjust the friction force between the tire and the ground simply by adjusting and replacing the friction strip 102, which not only reduces the tire maintenance cost but also extends the tire's service life. The anti-skid grooves 3 and the friction strip 102 on the surface of the tire body 4 are arranged alternately, increasing the friction force between the solid tire and the ground.
