An explosion-proof pure electric vehicle for underground coal mine operations

Abstract

The invention relates to an explosion-proof pure electric vehicle for operation in an underground coal mine. The explosion-proof pure electric vehicle comprises an H-shaped frame which is fastened to a drive axle at the bottom of the rear side of the frame, wheels connected to the two ends of a half shaft of the drive axle, respectively, explosion-proof power battery banks arranged at the two sides of the frame in front of and behind the drive axle, an explosion-proof high / low-voltage power distribution box arranged at one side of the frame between a driving cab and a compartment, an electric assembly of a steering / braking and cooling system arranged at the other side of the frame between the driving cab and the compartment, and a traction motor arranged between two transverse beams in front of the frame, wherein the output shaft of the traction motor is orderly connected with a speed reducer, a front transmission shaft, a parking brake and a rear transmission shaft, and the output end of the rear transmission shaft is in power connection with the input end of the drive axle. The explosion-proof pure electric vehicle is innovated in the aspects of the entire vehicle electric system and the battery explosion-proof technology, and the technology of the pure electric vehicle running on ground is combined with the explosion-proof requirement of operation in the underground coal mine, so that the explosion-proof pure electric vehicle is certainly convenient for daily use just as a diesel vehicle while zero emission is realized; besides, the explosion-proof pure electric vehicle meets the requirements of operation in the underground coal mine, and is a high-tech, safe and reliable vehicle.

Description

technical field [0001] The invention relates to a pure electric vehicle, in particular to an explosion-proof pure electric vehicle with Class I and Class II explosion-proof grades for underground operations in coal mines. Background technique [0002] At present, mining vehicles used in coal mines generally use diesel engines as power. Since diesel engines have exhaust emissions, they pollute the environment under the mines and are not conducive to the working environment of workers. Compared with fuel vehicles, electric vehicles have the advantages of low noise and vibration and good handling performance. Although pure electric vehicles for driving on the ground are already on the market, explosion-proof pure electric vehicles for coal mine underground operations are still in the research stage, and no products have been put into use. Due to the relatively high concentration of gas underground in coal mines, it is not possible to simply deliver pure electric vehicles on th...
