A light explosion-proof electric vehicle for mining

Abstract

The invention belongs to the field of auxiliary transportation devices for underground coal mines and particularly relates to a light mine explosion-proof electric vehicle. The light mine explosion-proof electric vehicle aims at solving the problem that no small flexible pollution-free explosion-proof electric vehicle for an underground coal mine exists at preset. A chassis body is of an integrated structure formed by welding steel plates and profile steel in an overlap joint manner. A motor transmission system comprises an explosion-proof motor, a differential speed reduction gearbox, a short transmission half shaft of a spherical cage structure, a long transmission half shaft of a spherical cage structure, a front left wet-type multi-disc brake and a front right wet-type multi-disc brake. A front independent suspension system structurally comprises a left shock absorber, a left swing arm and a left stabilizing rod and a rear independent suspension system structurally comprises a right shock absorber, a right swing arm and a right stabilizing rod. The left angle of elevation and the right angle of elevation are provided with shock absorber connection points, stabilizing rod connection points and swing arm connection points respectively. On the premise that the structural strength requirement is met, the lightweight design is adopted, the mass of the whole vehicle is reduced as much as possible, and the light mine explosion-proof electric vehicle has the beneficial effects of being low in mass, small in shape size, compact in structure, flexible and efficient in mechanic operation, free of pollution and the like and is mainly used for the fields of rescue, overhauling, inspection and the like of the underground coal mines.

Description

technical field [0001] The invention belongs to the field of underground auxiliary transportation equipment in coal mines, and in particular relates to a light explosion-proof electric vehicle for mining. technical background [0002] With the improvement of the advanced level of coal mine construction, more and more electromechanical equipment are widely used in mines, and the probability of equipment failures affecting the safety of coal mine production is also greatly increased. System emergency repair, site inspection of mechanical and electrical equipment, emergency troubleshooting and other services. At present, most of the explosion-proof vehicles that undertake this task are other types of explosion-proof vehicles that carry people or goods. These vehicles are not only of high quality, but most of them are The explosion-proof diesel engine trackless rubber-tyred vehicle with diesel engine as the power source not only causes high energy consumption in actual use, but ...

AI Technical Summary

Problems solved by technology

[0003] The invention aims at the lack of small, flexible and non-polluting explosion-proof electric vehicles in coal mines. The invention provides a light explosion-proof electric vehicle for mines. The vehicle is rated to carry four people and is specialized in patrolling and maintenance in coal mines.
