Underground construction safety equipment with good lighting effect and suitable for coal mine

Abstract

The invention relates to underground construction safety equipment with a good lighting effect and suitable for a coal mine. The underground construction safety equipment comprises a shell, four vehicle wheels, an adjusting mechanism and a search light. An air inlet pipe, an air exhaust pipe and an air inlet mechanism are arranged in the shell, and the adjusting mechanism comprises a moving unit,a swing rod, a movable block and at least two limiting rods. The air inlet mechanism comprises a driving unit, a compression pipe, a compression unit and a response unit. According to the undergroundconstruction safety equipment with the good lighting effect and suitable for the coal mine, the air inlet amount can be accurately quantitated through the air inlet mechanism, whether gas exists in the coal mine or not can be effectively detected by utilizing a gas sensor, when the air in a mine channel contains the gas, the concentration of the gas can be accurately detected, the probability of occurrence of safety accidents in the coal mine can be reduced, what's more, the underground construction safety equipment can effectively adjust the angle of the lighting lamplight through an adjusting mechanism, the lighting effect in the mine channel of the coal mine is improved, workers can timely discover the pavement condition in the mine channel, and the workers are prevented from falling down to hurting themselves.

Description

technical field [0001] The invention relates to the field of underground construction safety equipment, in particular to an underground construction safety equipment suitable for coal mines with good lighting effects. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. The vast majority of coal mines in my country are underground coal mines. Mine gas is a harmful gas mainly composed of methane in mines. Gas is a gas associated with coal formation and coal metamorphism. The gas generated in the process of coal formation is formed by the decomposition of cellulose and organic matter by the action of anaerobic bacteria in the initial stage of coal accumulation by ancient plants. [0003] When a small amount of gas is mixed with air, it is easy to explode in case of an open flame, but the existing underground construction safety eq...

AI Technical Summary

Problems solved by technology

[0003] When a small amount of gas is mixed with air, it is easy to explode in case of an open flame, but the existing underground construction safety equipment cannot effectively detect whether there is gas in the coal mine, and when the air in the mine tunnel contains gas, it cannot detect whether the gas concentration has exceeded Reaching the concentration that can cause an explosion will easily lead to safety accidents. Not only that, the existing underground construction safety equipment cannot effectively adjust the angle of the lighting, which reduces the lighting effect in the coal mine tunnel, making it impossible for workers to discover the road conditions in the mine tunnel in time. cause workers to fall
