An adjustable safety warning device for mines

Abstract

The invention discloses an adjustable safety warning device for a mine. The device comprises a mounting plate fixed to the top face of the mine, and a pair of first hinge supporting lugs is formed inthe mounting plate; a supporting rod is hinged to the first hinge supporting lugs through a hinge shaft, and a prompting plate is arranged at the lower end of the supporting rod; a first supporting plate and a second supporting plate are formed on the mounting plate, and a bearing rod is inserted into the first supporting plate; one end of the bearing rod abuts against the inner wall of the secondsupporting plate, an L-shaped connecting plate is formed on the outer wall of the first supporting plate, a baffle is formed on the bearing rod, and a first pressure spring is sleeved with the bearing rod; the two ends of the first pressure spring abut against the baffle and the connecting plate respectively, and the other end of the bearing rod penetrates out of the connecting plate and is connected with a piston rod of an air cylinder; sinking tables are formed in the portions, on the front side and the rear side of the mounting plate, at the bottom face of the mine respectively; the frontsinking table and the rear sinking table are internally provided with a front trigger and a rear trigger respectively. The device is good in safety prompt effect and capable of avoiding collisions.

Description

Technical field: [0001] The invention relates to the technical field of mine warning parts, in particular to an adjustable safety warning device for mines. Background technique: [0002] Mining projects are divided into coal mines and non-coal mines. Mining is the technology and science of extracting mineral resources from the earth's crust or surface. It generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and dressing of coal and oil. Its essence is the selective collection and processing of materials. The handling process. Mining industry is an important raw material extraction industry, such as metal ore is the main raw material of metallurgical industry, non-metallic ore is chemical raw material and building materials, coal and oil are important energy sources. At present, dangers are prone to occur in the mining process, and warning signs need to be installed in the mine. At present, some slogans are not ...

AI Technical Summary

Problems solved by technology

At present, dangers are prone to occur in the mining process, and warning signs need to be installed in the mine. At present, some slogans are not eye-catching, or the signs of the slogan are set on the side wall of the mine, which is easy to hit when the cart is pushing. Or installed on the top of the mine, although the collision is avoided, the warning effect is poor
