Description

A kind of anti-shock protection device for coal mine conveyor belt

technical field

The utility model relates to the field of coal mines, in particular to an anti-impact protection device for a coal mine conveyor belt.

Background technique

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig underground tunnels to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, it is generally chosen to directly peel off the surface soil layer to excavate the coal, which is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and related facilities. A coal mine is a reasonable space dug by humans when excavating a geological layer rich in coal, usually including roadways, wells and mining faces. Coal is the most important solid fuel and a kind of combustible organic rock. It is formed by luxuriant plants growing in a certain geological age, gradually accumulating into a thick layer in a suitable geological environment, and buried in the bottom of the water or in the sediment, and formed by natural coalification in a long geological age. When the coarse crushing system of the coal mine transfers the material from the higher conveyor belt to the lower conveyor belt, the impact on the conveyor belt is caused by the high drop distance and the large coal mine particles. The rollers of the conveyor belt are usually fixedly installed. The tension and elasticity of the conveyor belt itself and the installation of some tensioning roller devices for buffering are still easy to cause damage to the conveyor belt. At the same time, it also causes a large working pressure on the rollers, and the rollers need to be replaced frequently. , increasing production costs.
