A reversible safety warning mechanism used in mines

Abstract

The invention discloses a turnover safety warning mechanism used in a mine. The turnover safety warning mechanism used in the mine comprises a mounting board fixed to the top face of the mine; a pairof hinge supporting lugs are formed on one side of the mounting board; a supporting rod is hinged to the hinge supporting lugs through a first hinged shaft; a torsion spring is inserted on the first hinged shaft in a sleeving mode; a prompt board is installed at the lower end of the supporting rod; a hinge groove is formed in the supporting rod; the lower end of an L-type adjusting rod is hinged in the hinge groove through a second hinged shaft; a connection block is formed at the upper end of the adjusting rod and inserted on a support shaft; the support shaft is inserted into a guide grooveand provided with a sliding block; a lead screw is screwed on the sliding block; one end of the lead screw is connected with a rotary shaft of a drive motor; sinking tables are formed at the positions, on the front side and the rear side of the mounting board, of the bottom face of the mine; and a front trigger is arranged in the sinking table at the front side, and a rear trigger is arranged in the sinking table at the rear side. The turnover safety warning mechanism used in the mine is good in safety prompt effect and can also avoid collision.

Description

Technical field: [0001] The invention relates to the technical field of mine warning parts, in particular to a reversible safety warning mechanism used in 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 ar...

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, but the warning effect is poor, it is necessary to improve
