A lift-type safety warning device in a mine

Abstract

The invention discloses a lifting safety warning device in a mine cave. The mine cave is included, the middle layer of the mine cave is provided with warning plates, warning slogans are fixed to the front end surfaces of the warning plates, sinking tables are formed in mine cave bottom surfaces on the front and rear sides of the warning plates, a front trigger and a rear trigger are respectively arranged in each sinking table, first connecting seats are fixed in the middles of the rear end surfaces of the warning plates, second connecting seats are fixed to the rear end surfaces of the warningplates on both sides of the first connecting seats, vertical guide posts are fixedly inserted into the second connecting seats, vertical lead screws are fixedly inserted into the first connecting seats, the upper ends of the lead screws and the guide posts are inserted in a support plate and an installing top plate, the support plate is fixed to the lower end surface of the installation top plate, the installation top plate is fixed to the top surface of the mine cave, and inserting holes opposite to the lead screws and the guide posts are formed in the upper side of the mine cave. The deviceoptimizes and improves safety prompts and the warning slogans installed on the top of the mine cave, avoids collision, and has the function of high effective and good safety prompt.

Description

Technical field: [0001] The invention relates to the technical field of mine warning parts, and more specifically relates to a lift-type safety warning device in a mine. 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 within the Earth's crust or from the surface. Generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. 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. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. At present, there are dangers i...

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
