[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1-3As shown in the figure, the present utility model provides a technical solution: a self-locking underground material rack, which includes two symmetrically distributed rack bodies. Each of the two rack bodies includes a base 1, two side plates 2, and a limiting rod 4. The bottoms of the two side plates 2 are connected to both ends of the base 1. The base 1 and the two side plates 2 are both made of 16# channel steel. The upper sides of the two bases 1 are used for placing underground related materials. The limiting rod 4 is arranged between the two side plates 2. A plurality of square holes 3 are formed in each of the two side plates 2. A steel wire rope 8 is connected in the lowermost square hole 3 on each of the two side plates 2. After passing the steel wire rope 8 for anti-impulse limiting through the two lowermost square holes 3 on both side plates 2, it is fixed to the roadway wall to prevent the material rack from rushing towards the center of the roadway when impact ground pressure occurs. The steel wire rope 8 plays a fixing role. The size of the square hole 3 is 3 cm * 5 cm, and the distance between the square holes 3 on the two side plates 2 is 15 cm. Both ends of the limiting rod 4 are connected with anchor bolts 5. The anchor bolts 5 can prevent the limiting rod 4 from falling off. The two ends have different lengths and droop under the action of their own weight to achieve a self-locking effect. The lengths of the two anchor bolts 5 are 5 cm and 10 cm respectively. Place the underground related materials on the base 1. Both ends of the limiting rod 4 are inserted into the square holes 3 on the two side plates 2. Under the action of gravity, the two side anchor bolts 5 naturally droop and are in an upright state to avoid slipping out of the square holes 3, realizing the self-locking between the limiting rod 3 and the two side plates 2. Fix the underground related materials inside the base 1, the two side plates 2, and the limiting rod 3, which can achieve a good fixing effect on the underground related materials. A roller 6 with a 1 m belt bottom is arranged on the bottom side of the base 1, and both sides of the axle of the roller 6 are connected to the base 1 with steel plates 7. The roller 6 plays a role in supporting and facilitating movement.

[0023] The operation steps of the present utility model are as follows:

[0024] After passing the steel wire rope 8 for anti-impulse limiting through the two lowermost square holes 3 on both side plates 2, fix it to the roadway wall to prevent the material rack from rushing towards the center of the roadway when impact ground pressure occurs. Place the underground related materials on the base 1. Both ends of the limiting rod 4 are inserted into the square holes 3 on the two side plates 2. Under the action of gravity, the two side anchor bolts 5 naturally droop and are in an upright state to avoid slipping out of the square holes 3, realizing the self-locking purpose between the limiting rod 3 and the two side plates 2. Fix the underground related materials inside the base 1, the two side plates 2, and the limiting rod 3, which can achieve a good fixing effect on the underground related materials.
