[0001] The utility model relates to the technical field of anti-skid devices, in particular to an anti-skid device for a coal mine underground transport belt. Background Art

[0002] The underground conveyor belt of a coal mine is an important equipment used to transport coal and other materials underground in a coal mine. The main function of the underground conveyor belt of a coal mine is to transport coal, rock, ore and other materials excavated from the mining face or other working faces from the mining site to the ground of the coal mine or other processing facilities.

[0003] In the process of using belts to transport coal, water needs to be sprayed on the surface of the coal to reduce dust and the possibility of fire. However, too much water spraying or a large amount of water flowing on the surface of the belt will cause the belt surface to be too slippery, thereby affecting the transportation of coal blocks. Therefore, a new type of anti-slip device for underground coal mine transportation belts is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides an anti-skid device for underground coal mine transportation belt, which is mainly used to solve the problem that in the process of using the belt to transport coal, water needs to be sprayed on the surface of the coal to reduce dust and reduce the possibility of fire. However, excessive water spraying or a large amount of water flowing on the surface of the belt will cause the belt surface to be too slippery, thereby affecting the transportation of coal blocks. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0020] A coal mine underground transport belt anti-skid device, comprising: a horizontal rod 1, two torsion springs 2, after the user installs the horizontal rod 1 above the belt conveyor through the installation mechanism 10, the slider 3 is slidably inserted into the inner wall of the horizontal rod 1, so that the water outlet pipe 4 fixedly penetrating the surface of the slider 3 is arranged above the belt, and the water inlet pipe 5 fixedly penetrating the surface of the water outlet pipe 4 is connected to one end of an external faucet, so that water can be passed into the inside of the water outlet pipe 4, and the surface of the water outlet pipe 4 is slidably plugged with a water baffle 6, and the water baffle 6 is fixedly installed with a force rod 7, and the surface of the force rod 7 is slidably sleeved There is a spring 8, and the two ends of the spring 8 are fixedly installed on the surface of the water baffle 6 and the force rod 7 respectively, and the surface of the horizontal rod 1 is rotatably installed with a pressure plate 9 through two torsion springs 2. Therefore, the pressure plate 9 is pressed on the surface of the force rod 7, so that the water baffle 6 can be limited on the inner wall of the water outlet pipe 4. When coal passes through the surface of the belt conveyor, it will drive the pressure plate 9 to rotate. At this time, under the action of the spring 8, the force rod 7 will drive the water baffle 6 to slide on the inner wall of the water outlet pipe 4, so that the water inside the water outlet pipe 4 can flow on the surface of the coal. The installation method of the two torsion springs 2 is: The mounting groove 11 is fixedly mounted on the fixing rod 12, and the pressing plate 9 is rotatably sleeved on the surface of the fixing rod 12. The two torsion springs 2 are slidably sleeved on the surface of the fixing rod 12 and one end is fixedly mounted on both sides of the pressing plate 9. The other ends of the two torsion springs 2 are fixedly mounted on both sides of the inner wall of the mounting groove 11. Therefore, when the pressing plate 9 rotates, the two torsion springs 2 will be twisted, thereby applying a force to the pressing plate 9 to rebound to its original position. The main components of the mounting mechanism 10 are: two mounting rods 1001 respectively fixedly mounted on both ends of the horizontal rod 1. The user moves the two torsion springs 2 to the horizontal rod 1. After the mounting rods 1001 are fitted on both sides of the belt conveyor, a number of mounting bolts 1002 are respectively threadedly inserted into the surfaces of the two mounting rods 1001 and then threadedly inserted into both sides of the belt conveyor, so that the horizontal rod 1 can be limited above the belt conveyor. The main components of the pressure plate 9 are: a main rod 901 that is rotatably sleeved on the surface of the fixed rod 12, and an extension rod 902 is slidably inserted into the inner wall of the main rod 901. The user can control the position of the extension rod 902 on the inner wall of the main rod 901 through the adjustment mechanism 13, thereby controlling the total length of the main rod 901 and the extension rod 902.

[0021] During use, the user installs the horizontal rod 1 above the belt through the installation mechanism 10, and then connects the water inlet pipe 5 to one end of the external water pipe to transport the coal through the belt. After the coal blocks pass through the pressure plate 9, they will lift the pressure plate 9. After the pressure plate 9 is lifted, under the action of the elastic force of the compressed spring 8, the force rod 7 will drive the water baffle 6 to slide on the inner wall of the water outlet pipe 4. At this time, water can be sprayed out from one end of the water outlet pipe 4 to flush the coal blocks. At the same time, the water output is also related to the amount of coal on the surface of the belt. When the amount of coal is insufficient, no water will be sprayed, thereby ensuring that too much water will not flow down the surface of the belt, avoiding the belt surface from slipping, and fully reflecting the practicality of the device.

[0022] like Figure 1 , Figure 4 As shown, in some embodiments, in order to further optimize the solution, a spray box 14 with a plurality of small holes on the inner wall is fixedly installed at one end of the water outlet pipe 4, and the water entering the water outlet pipe 4 will be discharged through the plurality of small holes, thereby achieving a relatively uniform spraying of the water. When in use, the user can threadably insert two limit bolts 15 into the surface of the slider 3, so that the two limit bolts 15 are both threadedly inserted into the surface of the horizontal rod 1, so as to further limit the slider 3. The adjustment mechanism 13 includes a driving threaded rod 1302, and a mounting plate 1301 is fixedly installed on the surface of the main rod 901. The driving threaded rod 1302 is rotatably inserted into the surface of the extension rod 902, and the driving threaded rod 1302 is threadedly inserted into the surface of the mounting plate 1301. Therefore, the user rotates the driving threaded rod 1302 to drive the extension rod 902 to slide on the inner wall of the main rod 901.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
