Mining flame-proof and intrinsic safety type charging device

Abstract

The invention discloses a mining flame-proof and intrinsic safety type charging device. The efficient and reliable charging process meeting related safety laws and regulations in the underground environment is achieved. A front-end assembly is connected with a rear-end assembly in a matched mode through movement for charging; ,a fixing support of the rear-end assembly can be fixedly arranged in a roadway, the end of a power output shaft of an explosion-proof motor is located in the fixing support, a butt joint male head is fixedly arranged at the end of the power output shaft of the explosion-proof motor, a travel switch is arranged in the fixing support, the front-end assembly is movably arranged in the roadway a butt joint female head of the front-end assembly is arranged at the end of a power input shaft of the anti-explosion generator, the power input shaft of the anti-explosion generator is located on one side of an anti-explosion shell end cover, and a collision block is arranged on the anti-explosion shell end cover. and the butt joint male head and the butt joint female head can be inserted together in a matched mode, the front-end assembly and the rear-end assembly are connected together through the butt joint male head and the butt joint female head, and the collision block is used for triggering the travel switch to act when the front-end assembly and the rear-end assembly are connected in a matched mode.

Description

technical field [0001] The invention relates to an explosion-proof and intrinsically safe charging device for mining, which belongs to the technical field of coal mine underground equipment charging, and in particular relates to an explosion-proof and intrinsically safe charging device applicable to the coal mine underground environment and working conditions. Background technique [0002] In the coal mine underground environment and working conditions, in order to ensure safe production, the use of intelligent equipment that can be charged independently is greatly limited. Currently, the charging devices on the market mainly adopt two types: plug-in charging structure and wireless charging structure. There are major safety hazards in the underground environment of coal mines. [0003] The traditional plug-in charging structure will generate an arc when it is separated, which is unacceptable for use in an underground coal mine environment. And the explosion-proof plug and s...

[0002] In the coal mine underground environment and working conditions, in order to ensure safe production, the use of intelligent equipment that can be charged independently is greatly limited. Currently, the charging devices on the market mainly adopt two types: plug-in charging structure and wireless charging structure. There are major safety hazards in the underground environment of coal mines

[0003] The traditional plug-in charging structure will generate an arc when it is separated, which is unacceptable for use in an underground coal mine environment

As for the explosion-proof plug and socket, its structure is difficult to maintain a complete explosion-proof type during use without human intervention.

Conventional explosion-proof plugs and sockets, when applied to autonomous intelligent charging equipment, after the charging is completed, the live contacts will be directly exposed to the working environment, which may cause sparks and explosions

[0004] At present, the wireless charging mode that is gradually promoted and used has the advantages of high technical content and easy operation, but under the premise of meeting the above regulations, the time cost required to complete charging will be unacceptable; Valve power will become a safety hazard in turn
