Intelligent auxiliary transporting system for underground coal mine diesel and electric independently-driven rubber-tired vehicle

Abstract

The invention discloses an intelligent auxiliary transporting system for an underground coal mine diesel and electric independently-driven rubber-tired vehicle. Two types of power sources of an explosion-proof motor and an explosion-proof electric injection diesel engine operate in an underground coal mine, the time-sharing independently-driven dual-power trackless rubber-tired vehicle executes the mine auxiliary transporting task, and zero emission of harmful gas such as CO and NOx in a mine main roadway is achieved; noise of the head of a driver during operation of the vehicle at the wired section is lowered; the cost of fuel consumption per hundred kilometers of the rubber-tired vehicle in an unwired roadway is saved; the problems that during long-distance climbing of a diesel locomotive, power attenuation is quick, the efficiency is low, and emission is high are solved; the problem that during long-distance downhill of the diesel locomotive, the braking efficiency is lowered due tocontinuous braking is solved; meanwhile braking energy can be secondarily absorbed and reutilized, and thus energy resources are saved; the operation sate of the vehicle can be real-timely managed and controlled on line through intelligent dispatching, and thus the safety of auxiliary transporting is improved; and the operation environment of mine workers is improved, and the intelligent auxiliary transporting system is a novel underground coal mine trackless auxiliary transporting system.

Description

technical field [0001] The invention relates to the field of underground auxiliary transportation in coal mines, in particular to an intelligent auxiliary transportation system for underground diesel-electric independently driven rubber-tyred vehicles in coal mines. Background technique [0002] Trackless rubber-tyred vehicles in coal mines have been widely used in the past 20 years due to their flexible maneuverability, fast speed, point-to-point non-reloading transportation, strong climbing ability, and large load capacity, which have greatly improved mine production efficiency. 95% of the power source of existing rubber-tyred vehicles is provided by explosion-proof diesel engines, and 5% is provided by lead-acid batteries and lithium batteries. After years of use, some insurmountable problems have been exposed: the exhaust emissions of explosion-proof diesel engine trackless rubber-tyred vehicles barely reach the national standard. According to the II standard, the concen...

AI Technical Summary

Problems solved by technology

95% of the power source of existing rubber-tyred vehicles is provided by explosion-proof diesel engines, and 5% is provided by lead-acid batteries and lithium batteries. After years of use, some insurmountable problems have been exposed: the exhaust emissions of explosion-proof diesel engine trackless rubber-tyred vehicles barely reach the national standard. According to the II standard, the concentration of CO, NOx and other harmful gases in the air in the roadway seriously exceeds the standard, which directly affects the health of coal mine employees; the noise of vehicles is generally high during operation, generally exceeding 90dB(A); the fuel consumption per 100 kilometers of vehicles with the same load Compared with the ground vehicle, it is more than 2 times; the vehicle is generally suitable for roadway conditions below 8 degrees (continuous ramps are generally within 500m), and it is difficult to meet the mine needs of geological conditions with large coal deposits in my country. The problem of adaptability is prominent; vehicles powered by lead-acid batteries have problems such as long battery charging time, few battery charge and discharge times, and high maintenance costs; lithium battery rubber-wheeled vehicles are also in their infancy, with short mileage and later use and maintenance. High cost and other problems, and the battery has secondary pollution

[0003] For underground coal mines with poor air circulation, the "four highs and one low" characteristics of high vehicle exhaust emissions, high noise, high failure rate, high fuel consumption and operating costs, and low efficiency are prominent, resulting in the "auxiliary" cost of coal production Exceeding the normal production cost, and has already caused certain harm to human health
