TECHNICAL FIELD
[0001] The utility model belongs to the engineering tire technical field, concretely relates to an engineering tire for mine loader. BACKGROUND
[0002] The loader is mechanical equipment, and is mainly used for collecting and conveying construction loading of gravel earth materials in various mines such as phosphate rock, iron ore, copper mine, gold mine, silver mine, lead-zinc mine and coal mine tunnel, water and electricity, and tunnel engineering. When the gravel earth material conveying for the mine is used, uphill and downhill are often encountered, so the engineering tire with strong ground adhesion needs to be used.
[0003] The engineering tire refers to the tire with good wear resistance and less heat generation, and is usually composed of the cord layer, the bead, the belt layer, the tread, the shoulder and the side wall. In the prior art, in order to improve the ground adhesion of the engineering tire, the strip-shaped pattern groove is usually arranged on the tread. However, when the pattern groove is deep, the stone is easily clamped in the groove, so that the ground adhesion of the tire is reduced, and even the tread is damaged. When the pattern groove is shallow, the ground adhesion of the tire is insufficient, and the skidding phenomenon is easily generated. UTILITARY MODEL

[0015] The mine loader engineering tire has the advantages that two groups of grooves are arranged on the tire tread, and the two groups of grooves are arranged in a staggered manner, so that the tire grip is effectively improved. The protrusions arranged in the grooves can prevent large stones from being clamped in the grooves and causing the tire grip to be reduced or even the tire tread to be damaged, under the premise of ensuring the tire grip. Even if some stones are clamped in the grooves, the arrangement of the protrusions can also prevent the stones from entering the bottom of the grooves, so that the stones can be easily pried out by the workers, and the stones can be easily cleaned.

[0035] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0036] The present embodiment provides an engineering tire for mine loader, comprising a tread 2 and a shoulder 1.
[0037] Two groups of grooves 3 are formed on the tread 2, and the two groups of grooves 3 are uniformly and spaced arranged along the circumferential direction. The two groups of grooves 3 are staggered, the first group of grooves 3 extends to the first side shoulder 1, and the second group of grooves 3 extends to the second side shoulder 1. The inner bottom of the groove 3 is provided with a protrusion 4.
[0038] For example, referring to Figure 1 The tread 2 is the outermost part of the tire, which directly contacts the ground and provides traction and grip. The two sides of the tread 2 are the shoulders 1 of the tire. Two groups of grooves 3 are formed on the tread 2, and the two groups of grooves 3 are uniformly and spaced arranged along the circumferential direction. The two groups of grooves 3 are respectively located in the two side regions of the tread 2, and are staggered to avoid overlapping of the two groups of grooves 3. The two groups of grooves 3 correspond to the two side shoulders 1 respectively, and the grooves 3 extend to the corresponding shoulders 1. The inner bottom surface of the groove 3 is fixedly provided with a protrusion 4. The protrusion 4 and the tread 2 can be an integral structure.
[0039] Based on the above structure, the engineering tire provided by the present embodiment can effectively improve the tire grip by forming two groups of grooves 3 on the tread 2, and the two groups of grooves 3 are staggered. Among them, the protrusion 4 is arranged in the groove 3, which can avoid the large stones from being stuck in the groove 3 under the premise of ensuring the grip, so as to reduce the tire grip and even damage the tread 2. Even if some stones are stuck in the groove 3, the arrangement of the protrusion 4 can also avoid the stones from entering the inner bottom of the groove 3, which is convenient for the staff to quickly pick out and clean. One end of the groove 3 extends to the shoulder 1, which is convenient for picking out the stones from the side of the tire, and also helps to dissipate heat to both sides of the tire, improving the heat dissipation efficiency of the tire.
[0040] On the basis of the above technical solutions, in the technical solutions provided by the embodiment, the cross section of the protrusion 4 can be isosceles trapezoidal structure, the long side of the isosceles trapezoidal structure is located at the side of the protrusion 4 close to the inner bottom of the groove 3, and the short side of the isosceles trapezoidal structure is located at the side of the protrusion 4 away from the inner bottom of the groove 3.
[0041] For example, referring to Figure 2 , the left end of the groove 3 extends to the left shoulder 1, the protrusion 4 is located at the middle position of the groove 3, and the cross section of the protrusion 4 is isosceles trapezoidal structure, that is, the left and right sides of the protrusion 4 are both slopes. When the stones or soil in the groove 3 are stuck, the slopes of the protrusion 4 help to quickly pick out the stones or soil, which is convenient for cleaning.
[0042] Of course, the surface of the protrusion 4 can also be curved.
[0043] For example, referring to Figure 3 , the surface of the protrusion 4 is smooth structure, which has better guiding effect and is convenient for cleaning.
[0044] Further, the heat dissipation holes 5 can be arranged on the side wall of the protrusion 4.
[0045] For example, referring to Figures 2-3 , the heat dissipation holes 5 are arranged on the left and right side walls of the protrusion 4, so that the heat on the right side of the protrusion 4 can be transferred to the left side of the protrusion 4 through the heat dissipation holes 5, and then dissipated to the outside of the tire from the left shoulder 1, thereby improving the heat dissipation efficiency.
[0046] In the technical solutions provided by the embodiment, the tire further includes a sidewall 6. The sidewall 6 is used to connect the tread 2 and the hub, and protect the inner structure of the tire. For the mine road surface, referring to Figure 6 , the sidewall 6 is easily scratched by the sharp parts of the ore during driving, which may cause the internal structure of the sidewall 6 to be cut and torn, even the inner tube to be torn, so that the tire leaks air, the vehicle cannot continue to drive, and the maintenance is difficult.
[0047] In order to avoid the above situation, the inner side of the sidewall 6 can be provided with a reinforcing net 7.
[0048] For example, referring to Figure 2 , the tire further includes a cord layer 10, a belt layer 11, and a bead wire 12. The cord layer 10, the belt layer 11, and the bead wire 12 are all prior art, and the specific positional relationship thereof in the tire is also prior art. Here, these prior structures are cited only to facilitate the understanding of the positional relationship of the reinforcing net 7.
[0049] Specifically, the two side parts of the tire are the sidewall 6. The sidewall 6 is provided with a reinforcing net 7, and the reinforcing net 7 is located outside the cord layer 10, so that the reinforcing net 7 can protect the internal structure of the sidewall 6 (the cord layer 10 and the like) and improve the cutting resistance of the tire to avoid the sharp part scratching the internal structure of the sidewall 6.
[0050] Referring to Figure 4 The reinforcing net 7 can be a ring structure. The reinforcing net 7 is coaxial with the tire and can locally reinforce the sidewall 6 area.
[0051] The reinforcing net 7 can also be a ring net structure. The ring net structure can sufficiently reduce the weight and avoid increasing the weight of the tire.
[0052] For example, the reinforcing net 7 can be a ring steel mesh. The steel mesh has high elasticity and toughness and can deform to a certain extent when subjected to external force. Moreover, the steel mesh can maintain good performance stability during long-term use.
[0053] The reinforcing net 7 can be a ring aramid fiber mesh. Aramid fiber is a high-performance fiber with high toughness and strength, so that the reinforcing net 7 has strong cutting resistance.
[0054] Referring to Figure 5 The reinforcing net 7 can include two ring connecting lines 9 and a plurality of reinforcing rods 8.
[0055] The plurality of reinforcing rods 8 are uniformly and circumferentially spaced apart. One ring connecting line 9 (a ring connecting line 9 with a smaller diameter) connects the inner ends of the plurality of reinforcing rods 8, and the other ring connecting line 9 connects the outer ends of the plurality of reinforcing rods 8, thereby forming a ring net structure.
[0056] The reinforcing rod 8 can play a role in cutting resistance and thereby protect the internal structure of the sidewall 6.
[0057] The reinforcing rod 8 can be two or more hard rods connected together by a connecting rope to form a relatively long connecting structure, so that the hard rods can move relative to each other to avoid the reinforcing rod 8 being a rigid whole.
[0058] The hard rod can be a carbon fiber rod, which has high strength and light weight. It can not only significantly improve the cutting resistance of the tire, but also avoid increasing the weight of the tire.
