An underground trackless rubber wheel vehicle exhaust gas collecting and discharging device

Abstract

The invention belongs to the field of mine ventilation and safety and underground environment protection and particularly relates to an exhaust collection and emission device for an underground trackless rubber-tired vehicle. The exhaust collection and emission device comprises a wire rope guide line disposed on a roadway wall between a start point and an end point of an exhaust collection and emission segment. The wire rope guide line is sleeved with a sliding lock which can slide. A gas collection hood corresponding to an exhaust hole of the rubber-tired vehicle is fastened on the sliding lock and is communicated with a gas delivery pipe. The gas delivery pipe is communicated with an exhaust hole inside a ventilation roadway. The part of the exhaust hole, in the front part the rubber-tired vehicle, is provided with a sliding rack connected with the sliding lock. The sliding lock and the sliding rack move synchronously. Collected exhaust can be discharged to a master ventilation roadway or a special ventilation roadway through the gas delivery pipe and a vacuum pump, so that the pollution of air environment of an underground operation site by the exhaust can be reduced. A special exhaust purifier can be provided to purify the collected exhaust, so that pollution of the air environment is reduced.

Description

technical field [0001] The invention belongs to the fields of mine ventilation and safety, and underground environmental protection, and in particular relates to an exhaust gas collecting and discharging device for an underground trackless rubber-tyred vehicle. Background technique [0002] With the improvement of coal mine mechanization, auxiliary transport vehicles powered by explosion-proof diesel engines, especially trackless explosion-proof rubber-tyred vehicles (hereinafter referred to as rubber-tyred vehicles), are more and more widely used underground, such as material and personnel transport vehicles, scraper Cars and bracket transport vehicles, etc., they have the advantages of safety, flexibility, speed and economy. While rubber-tyred vehicles bring efficiency to coal mine production, they also have some negative effects, the most important of which are the pollution of the exhaust gas emission to the underground air environment and the harm to the health of coal ...

AI Technical Summary

Problems solved by technology

If the excessively discharged tail gas cannot be treated in a timely and effective manner, it will inevitably cause great pollution to the underground air environment

[0008] Therefore, until there is no more effective device to deal with the excessive exhaust gas discharged from special road sections, there is an urgent need for a tail gas treatment method for the phenomenon of sharp increase in the exhaust gas emissions of rubber-tyred vehicles in special road sections underground, and to set up corresponding devices. Excessive exhaust gas from these road sections is transported out of the underground space environment to protect the underground air environment, reduce the damage of exhaust gas to the physical and mental health of underground workers, and ensure safe production in coal mines
