Mining explosion-proof wireless miner lamp charging cabinet

Abstract

The invention discloses a mining explosion-proof wireless miner lamp charging cabinet in the field of coal mine safety equipment. The cabinet comprises a supporting box, the bottom of the supporting box is fixedly provided with wheels, one side surface of the supporting box is provided with a first limiting groove, the inner wall of the first limiting groove is movably connected with a pulley, andthe center of the pulley is fixedly provided with a bearing. A first handle rod is fixedly connected to the circle center of the bearing, a sliding block is fixedly connected to one end of the firsthandle rod, and a connecting rod is fixedly installed on one side of the sliding block. When the charging cabinet is installed, the first handle rod and the pulley are pushed to rotate in the first limiting groove, then the sliding block is driven to move, the sliding block pushes the first supporting plate through the connecting rod and pushes the first supporting plate out of the supporting box,the first limiting groove also limits the pulley, the sliding block is prevented from falling off from one side of the supporting box, after the first supporting plate is pushed out of the supportingbox, the supporting frame is moved downwards, and through limiting of the second limiting grooves and the limiting strips, the supporting frame moves downwards stably.

Description

technical field [0001] The invention relates to the field of coal mine safety equipment, in particular to a mine explosion-proof wireless miner's lamp charging cabinet. Background technique [0002] Miner's lamp is the abbreviation of mining lamps or industrial and mining lamps, and the general name of special lighting lamps used in mines. The miner's lamps developed and sold by Tongming Electric are suitable for underground coal mines where there is a risk of gas (methane) coal dust explosion; the roadways in the bottom mining area can also be used in infrastructure mine roadways and chambers with large water spray. Main application: It is used for safety lighting and emergency rescue lighting in environments with flammable, explosive and combustible gases such as mines, petroleum, chemicals, railways, transportation, and storage. It is especially suitable for underground coal mines, tunnels and various underground projects and civil air defense projects. Applicable perso...

Problems solved by technology

[0003] In the existing wireless miner's lamp charging cabinet, the charging cabinet is usually directly fixed on the ground with screws, and there is no other anti-dumping device. The stability of the placement is poor, and there is a risk of tipping over. Hidden dangers, sometimes it is necessary to move the charging cabinet according to the actual situation of mining. The existing charging cabinet is inconvenient to move, and it takes time to move. When charging, there is no fixed device on the charging stand. If the battery cannot be charged, it will affect the next use
