Description

Technical Field

[0001] The present application relates to the field of explosion-proof tires specially used for mining engineering vehicles, and in particular to an explosion-proof tire tread specially used for mining engineering vehicles. Background Art

[0002] In the use scenarios of mining engineering vehicles, the road conditions that the tires come into contact with are relatively poor, especially there are many conical and knife-shaped ores. Tires working in such road conditions are required to have strong grip performance on the one hand, and on the other hand, they also have extremely high requirements for wear resistance and load-bearing performance.

[0003] At present, most of the tires used in mining engineering vehicles are mining tires, such as a new type of steel wire tire with Chinese patent announcement number CN209888561U, which includes an outer carcass layer and an inner carcass layer butt-jointed into a tire contour, and more than three belt layers are arranged between the outer carcass layer and the inner carcass layer along the circumferential direction of the outer carcass layer.

[0004] With respect to the above-mentioned related technologies, the inventors believe that although this type of mining tire can adapt to more complex road conditions, the manufacturing cost of the entire tire will be relatively high during the process of embedding the steel mesh structure of the tire into the tire and molding it. Utility Model Content

[0005] In order to improve the defect of relatively high manufacturing cost of mining tires.

[0006] The present application provides a special explosion-proof tire tread for mining engineering vehicles, which adopts the following technical solution:

[0007] A tread of an explosion-proof tire specially used for mining engineering vehicles comprises a tread body, wherein the tread body comprises seven rubber layers, wherein the rubber layers in the same layer comprise at least one rubber substrate, wherein a steel wire mesh is embedded in each rubber substrate; wherein each rubber substrate comprises two mutually parallel side edges and two mutually parallel oblique edges, wherein the two side edges and the two oblique edges form a rhombus shape, wherein the side edges on the same side of the rubber substrates at corresponding positions in adjacent rubber layers are sequentially overlapped and the oblique edges on the same side are mutually staggered.

[0008] In some embodiments, the wire mesh of the rubber substrate in five of the seven rubber layers includes interlaced threaded steel wires, and the threaded steel wires include first steel wires, and the outer side wall of the first steel wire is provided with a threaded external protrusion, or a plurality of annular threaded external protrusions are arranged at intervals on the outer side wall of the first steel wire.

[0009] In some embodiments, the steel wire mesh of the rubber substrate in the other two rubber layers of the seven rubber layers includes mutually staggered spiral steel wires, the spiral steel wires include at least two spiral second steel wires, and all the second steel wires in each spiral steel wire are intertwined with each other.

[0010] In some embodiments, when the rubber layer of the same layer includes a rubber substrate, when the rubber substrate is bent into a circular structure, two adjacent oblique edges are seamlessly butted against each other.

[0011] In some embodiments, when the rubber layer of the same layer includes at least two rubber substrates, adjacent oblique edges of adjacent rubber substrates are seamlessly spliced, and when all the spliced ​​rubber substrates are bent into a circular structure, two adjacent oblique edges are seamlessly butted against each other.

[0012] In some embodiments, adjacent rubber layers are bonded and fixed to each other.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The seven rubber layers are overlapped and a wire mesh is embedded in each rubber layer, so that the structural strength of the tire itself is better. At the same time, compared with traditional mining tires, the difficulty of embedding the wire mesh in the tire and the defective rate of molding are reduced, so that the manufacturing cost of the tire is effectively reduced. At the same time, each rubber layer adopts a diamond structure, which makes the diamond-structured rubber layer more fitting, tight and seamless during the splicing process.

[0015] 2. The wire mesh formed by the interlaced threaded steel wires is embedded in the rubber layer. On the one hand, it can enhance the matching viscosity between the wire mesh and the rubber layer, and on the other hand, it can enhance the ductility and shrinkage performance of the tire.

[0016] 3. The wire mesh formed by the interlaced spiral steel wires is embedded in the rubber layer. On the one hand, it can increase the softness of the tire itself, and on the other hand, it can increase the tire's tear resistance and explosion-proof performance. BRIEF DESCRIPTION OF THE DRAWINGS
