煤矿斜井常闭式防跑车装置设置

Setting of Normally Closed Type Anti-tram Running Device in Inclined Shaft of Coal Mine

介绍了煤矿轨道斜井常闭式防跑车装置的工作原理,根据防跑车装置最大防护距离并结合串车上下井时的最不利工况分析,提出了防跑车装置最大设置间距计算公式。通过设计实例详细分析防跑车装置设置原则,总结了目前防跑车装置设计时存在的主要问题并提出解决方案。

We introduce the working principle of normally closed anti-tram running device in inclined shaft of coal mine, accord- ing to the maximum protection distance of anti-tram running device and combined with the analysis of train going up and down the well under the most unfavorable condition, we propose the calculating formula of anti-tram running device for its maximum distance. Through detailed analysis of anti-tram running device setting principles by design example, we summarize the main problems of device design at present and propose solutions.
