Description

TECHNICAL FIELD

[0001] The utility model relates to solid tire technical field especially a mining polyurethane solid tire structure. BACKGROUND

[0002] Solid tires are commonly used in industrial vehicles and are widely used in harsh road conditions such as mines, factories, quarries and the like.

[0003] At present, the mining polyurethane solid tire is mostly directly poured and vulcanized on the surface of the rim to form an integral structure, and the polyurethane layer is relatively thick. When the surface pattern outer layer is worn, the entire tire cannot be used, but due to the relatively thick pouring of the polyurethane layer, a great waste is caused. SUMMARY

[0004] In order to solve the problems of the prior art, the utility model provides a mining polyurethane solid tire structure, which divides the polyurethane adhesive layer into two layers, uses a groove type connection (stainless steel material protrusion and groove) in the middle, and fits the pattern outer layer and the polyurethane inner layer together through interference fit. After the pattern outer layer is worn, the polyurethane inner layer and the rim are perfect, and the tire pattern outer layer can be directly replaced, greatly reducing the tire use cost.

[0005] The utility model solves the technical scheme adopted for the technical problems: a mining polyurethane solid tire structure, comprising a rim and a polyurethane adhesive layer, wherein the polyurethane adhesive layer is inlaid on the outer surface of the rim by a bonding process to form a solid tire, the polyurethane adhesive layer comprises a pattern outer layer and a polyurethane inner layer, the pattern outer layer is provided with a stainless steel protrusion, the polyurethane inner layer is provided with a stainless steel groove, and the pattern outer layer and the polyurethane inner layer are fit together through interference fit of the stainless steel protrusion and the stainless steel groove.

[0006] A plurality of bolts are further arranged on the rim, and the bolts are fixed through the pattern outer layer and the polyurethane inner layer.

[0007] The stainless steel protrusion is inlaid on the pattern outer layer by a bonding process.

[0008] The stainless steel groove is inlaid on the polyurethane inner layer by a bonding process.

[0009] The utility model has the beneficial effects that: the polyurethane adhesive layer is divided into two layers, a groove type connection (stainless steel material protrusion and groove) is used in the middle, and the pattern outer layer and the polyurethane inner layer are fit together through interference fit. After the pattern outer layer is worn, the polyurethane inner layer and the rim are perfect, and the tire pattern outer layer can be directly replaced, greatly reducing the tire use cost.
