Description

Technical Field

[0001] The utility model relates to the field of ore mining, and particularly relates to an underground ground anti-fragmentation assembly. Background Art

[0002] During the ore mining process, it is necessary to transport the ore in the roadway by a load-haul-dump (LHD) vehicle. Usually, a concrete floor needs to be laid at the bottom of the roadway. However, due to the large amount and frequent transportation of ore by the LHD vehicle, the floor is extremely easy to be damaged. In order to improve the strength of the floor, an underground ground anti-fragmentation assembly is provided in this application. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide an underground ground anti-fragmentation assembly to solve the problem that the underground roadway floor is easily crushed by the LHD vehicle in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] An underground ground anti-fragmentation assembly includes

[0006] A roadway floor, on which a concrete layer is laid;

[0007] A plurality of positioning blocks, which are embedded in the surface of the concrete layer in parallel, and the opposite surfaces of two adjacent positioning blocks respectively have first limiting grooves;

[0008] A plurality of first limiting plates, which are arranged between two adjacent positioning blocks in parallel, and both ends of the first limiting plate respectively extend into the first limiting grooves of the two adjacent positioning blocks;

[0009] A plurality of convex bodies, which are fixedly connected to the first limiting plate, and the inner wall of the first limiting groove has convex grooves corresponding to the positions of the convex bodies, and the convex bodies extend into the convex grooves.

[0010] Preferably: The convex body and the side surface of the first limiting plate are in a T shape.

[0011] Preferably: There are a plurality of second limiting plates between two adjacent positioning blocks. Both ends of the second limiting plate respectively have insertion rods. The positions of the two side wall corners of the positioning block corresponding to the second limiting plate have second limiting grooves. The side wall of the second limiting groove has slots corresponding to the positions of the insertion rods. The second limiting plate extends into the second limiting groove, and the insertion rod is inserted into the slot.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By embedding positioning blocks in the concrete layer, this application can prevent the scraper from crushing the concrete layer and causing potholes on the ground. The first limiting plate and the convex body, as well as the second limiting plate and the insertion rod in this application, can effectively prevent the positions of two adjacent positioning blocks from being unstable and effectively prevent the positioning blocks from moving.

Detailed Description of the Preferred Embodiments

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-5 shown, an underground ground anti-crushing component includes

[0022] a roadway ground 10, on which a concrete layer 20 is laid;

[0023] a plurality of positioning blocks 30, which are embedded in parallel on the surface of the concrete layer 20, and the opposite surfaces of two adjacent positioning blocks 30 respectively have first limiting grooves 42;

[0024] a plurality of first limiting plates 40, which are arranged in parallel between two adjacent positioning blocks 30, and the two ends of the first limiting plate 40 respectively extend into the first limiting grooves 42 of two adjacent positioning blocks 30;

[0025] a plurality of convex bodies 41, which are fixedly connected to the first limiting plate 40, the inner wall of the first limiting groove 42 has a convex groove 43 corresponding to the position of the convex body 41, and the convex body 41 extends into the convex groove 43.

[0026] This embodiment is implemented as follows:

[0027] Through the positioning blocks 30 embedded in the surface of the concrete layer, the damage of the wheels of the scraper to the concrete layer 20 can be reduced, and the concrete layer 20 can be prevented from being easily crushed. At the same time, the first limiting plate 40 extends into the first limiting groove 42, and the convex body 41 extends into the convex groove 43, so that two adjacent positioning blocks 30 can have a certain mutual restraint force, which can effectively improve the stability of the positioning blocks 30.

[0028] The advantage of this application compared with the prior art is that it can prevent the concrete layer 20 in the underground roadway from being easily damaged.

[0029] Please refer to Figure 1 、 2 Figures 3 and 4, the convex body 41 and the side surface of the first limiting plate 40 are in a T shape;

[0030] The T-shaped convex body 41 and the second limiting plate 40 can improve the stability of the positioning block 30.

[0031] Please refer to Figure 4 、 5 Between two adjacent positioning blocks 30, there are several second limiting plates 50. Both ends of the second limiting plate 50 have insertion rods 51. At the positions corresponding to the second limiting plates 50 at the two side wall corners of the positioning block 30, there are second limiting grooves 52. At the positions corresponding to the insertion rods 51 on the side walls of the second limiting grooves 52, there are slots 53. The second limiting plates 50 extend into the second limiting grooves 52, and the insertion rods 51 are inserted into the slots 53;

[0032] By setting the second limiting plates 50 to extend into the second limiting grooves 52, the insertion rods 51 can be inserted into the slots 53, thereby further increasing the stability between adjacent positioning blocks 30.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
