A retractable safety warning device in a mine

Abstract

The invention discloses a telescopic safety warning device in a mine cave. The device comprises a mine cave body, the middle layer of the mine cave is provided with a warning plate, a warning slogan is fixed to the front end surface of the warning plate, a sinking table is formed on the bottom surface of the mine cave on the front and rear sides of the warning plate, a front trigger and a rear trigger are respectively arranged in the sinking table, the upper end surface of the warning plate is fixed to a plurality of telescopic rods, the telescopic rods are composed of a plurality of joint tubes, the adjacent joint tubes are in inserting connection, annular retaining rings are formed on the inner walls of the joint tubes, annular baffle rings are formed on the outer walls of the lower endsof the joint tubes, the baffle rings of the joint tubes of the lower layer abut against the retaining rings of the joint tubes of the upper layer, the top ends of the telescopic rods are fixed to a fixing block, and the fixing block is fixed to a top plate; a plurality of lower electromagnets are fixed to the rear end surface of the warning plate, and a plurality of upper electromagnets oppositeto the lower electromagnets are fixed to the top plate. According to the device, safety prompts and warning slogans installed on the top of the mine cave are improved and optimized, collision is avoided, and the device has the function of safety prompting with better effect.

Description

Technical field: [0001] The invention relates to the technical field of warning parts for mine caves, and more specifically to a telescopic safety warning device in a mine cave. Background technique: [0002] Mining projects are divided into coal mines and non-coal mines. Mining is the technology and science of mining mineral resources from the crust or the surface. Generally refers to the mining of metal or non-metallic deposits, and broadly speaking, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. The mining industry is an important raw material mining industry. For example, metal ores are the main raw materials of the metallurgical industry, non-metallic ores are chemical raw materials and building materials, and coal and petroleum are important energy sources. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. There are dangers in th...

Problems solved by technology

At present, there are dangers in the mining process; warning signs need to be installed in the mine, but some slogans are not eye-catching at present, 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 can be avoided, the warning effect is poor
