Description
技术领域technical field
本发明涉及煤矿井下辅助运输领域，尤其涉及一种煤矿井下柴电独立驱动胶轮车智能辅助运输系统。The invention relates to the field of underground auxiliary transportation in coal mines, in particular to an intelligent auxiliary transportation system for rubber-tyred vehicles with diesel-electric independent driving in underground coal mines.
背景技术Background technique
煤矿井下无轨胶轮车因其机动灵活、速度快、点对点不转载运输、爬坡能力强、载重能力大等优点，使得无轨辅助运输在近20年得到了广泛应用，大大提高了矿井生产效率。现有胶轮车的动力源95%由防爆柴油机提供，5%由铅酸蓄电池和锂电池提供，在多年的使用中暴露出来一些难以克服的顽疾：防爆柴油机无轨胶轮车尾气排放勉强达到国Ⅱ标准，巷道空气中CO、NOx等有害气体浓度严重超标，直接影响到煤矿员工的身体健康；车辆运行时普遍噪音较高，一般超过90dB（A）；同载重量的车辆百公里耗油量与地面车辆相比超过2倍以上；车辆普遍适用于8度（连续坡道一般在500m以内）以下的巷道条件，难以满足我国煤炭赋存落差大的地质条件矿井需求，长距离大坡度条件下适应性问题突出；以铅酸蓄电池为动力的车辆存在电池充电时间长，电池充放电次数少、维护费用高等问题；锂电池胶轮车也正处在起步阶段，存在续航里程短，后期使用维护成本高等问题，并且电池存在二次污染。The trackless rubber-tired vehicle in the coal mine has been widely used in the past 20 years because of its flexibility, high speed, point-to-point non-transportation, strong climbing ability, and large load capacity, which has greatly improved the mine production efficiency. 95% of the power source of the existing rubber-wheeled 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 diseases have been exposed: the exhaust emissions of explosion-proof diesel engine trackless rubber-wheeled vehicles barely reach the national level. Ⅱ standard, the concentration of CO, NOx and other harmful gases in the air of 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 of vehicles with the same load per 100 kilometers Compared with ground vehicles, it is more than 2 times; vehicles are generally suitable for roadway conditions below 8 degrees (continuous slopes are generally within 500m), and it is difficult to meet the geological conditions of mines with large differences in coal occurrence in China. Long-distance and large-slope conditions The problem of adaptability is prominent; vehicles powered by lead-acid batteries have problems such as long battery charging time, low battery charging and discharging times, and high maintenance costs; lithium battery rubber-wheeled vehicles are also in their infancy, with short cruising range and later use and maintenance. The cost is high, and the battery has secondary pollution.
对于空气流通不畅的煤矿井下，车辆尾气排放高、噪声高、故障率高、耗油与运行费用高、效率低的“四高一低”的特征突出，导致煤炭生产付出的“辅助”代价超出正常生产代价，并且已经对人身健康造成了一定伤害。提升无轨辅助运输的清洁化和智能化水平将大大改善矿井空气质量，大幅减轻人员劳动强度，直接关系到全国400万矿工的身体健康。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 "auxiliary" costs for coal production. It exceeds the normal production cost and has already caused certain harm to human health. Improving the clean and intelligent level of trackless auxiliary transportation will greatly improve the air quality of mines and greatly reduce the labor intensity of personnel, which is directly related to the health of 4 million miners across the country.
