Tunnel poisonous gas detecting device for mine engineering

Abstract

The invention discloses a tunnel poisonous gas detecting device for mine engineering. The tunnel poisonous gas detecting device comprises a vehicle body; crawler-type travelling mechanisms are symmetrically mounted on the two sides of the vehicle body; mounting holes are formed in the two sides of the vehicle body correspondingly and communicate with an explosive-proof cavity of the vehicle body; a main drive shaft and the mounting holes are connected through shaft seats I fixedly mounted in the mounting holes; shaft sleeves are embedded in the shaft seats I; a gas detection sensor is further mounted at the front end of the vehicle body through a lifting column; the gas detection sensor is wirelessly connected with an intrinsically safe type wireless communication module mounted in the explosive-proof cavity through an intrinsically safe type communication system; and an upper lifting column body moves up and down under driving of a stranded wire I. According to the tunnel poisonous gas detecting device, the possibility that explosion is caused by the travelling mechanisms in travelling is effectively avoided, safety performance is improved, meanwhile, and the situation that the gas detection sensor can detect the state and concentration of poisonous gas of different heights is achieved, so that the gas detection sensor effectively avoids top obstacles, and smooth passing of the vehicle body is guaranteed.

Description

Technical field [0001] The invention relates to the field of gas detection for mining engineering, in particular to a tunnel toxic gas detection device for mining engineering. Background technique [0002] In the mining tunnel of the mine, due to the large amount of toxic gas in the mine, it is necessary to conduct detection during the mining process. The existing detection method is to install detection sensors on the excavation surface of the mine tunnel. After adopting this method, although the flameproof sensor can be used for detection, the excavation machinery on the mining surface is not flameproof, and once the tunnel exists A large number of toxic and harmful gases, such as nitrogen oxides, carbon dioxide, etc., pose huge safety risks. Moreover, due to the fixed installation position of the traditional sensor, only the toxic gas state of the same height can be detected during the detection process, and the detection of the toxic gas state of other heights cannot be rea...

The existing detection method is to install detection sensors on the excavation and mining face of the mine tunnel. After adopting this method, although the explosion-proof sensor can be used for detection, the excavation machinery on the mining face is not explosion-proof, and once the excavation tunnel exists A large number of toxic and harmful gases, such as nitrogen oxides, carbon dioxide, etc., have huge potential safety hazards

Moreover, due to the fixed installation position of the traditional sensor, it can only detect the toxic gas state at the same height during the detection process, and the toxic gas state at other heights cannot be detected
