项目摘要

As working faces move to the deeper in a coal mine, it is desired to raise the transportation capacity or to increase the car speed. The largest problem for speeding-up of the underground car is how to maintain the track condition and its alignments as good as possible. For this purpose, a track monitoring car newly designed was manufactured and tested on the railway system in a coal mine, where the level, gage and deflection of rails and the velocity and vibration of the car were examined continuously.In order to develop an automatic monitoring system for the track conditions of underground railway transportation system in colliery, a track monitoring car with electronic and electrical equipment was manufactured and tested on a drift railway. Continuous records of the level, gage and deflection of rails and the velocity and vibration of the car were considered as reasonable comparing with those data obtained by manual measurement. The digital output display on the monitoring car helps the operator to watch the condition of rail on real time. Therefore, this car is considered satisfactory for the requirements of the rail monitoring. The car, which were traveling at speed of 25km/h so far, has been sped up to 40km/h with this rail monitoring system.

随着工作面向深部移动，需要提高运输能力或提高车速。地铁车辆提速的最大问题是如何保持轨道状况及其线形尽可能好。为此，研制了一种新型轨道监测车，并在某煤矿的轨道系统上进行了试验，连续检测了轨道的水平、轨距、挠度、速度和振动，为开发煤矿井下轨道运输系统的轨道状态自动监测系统奠定了基础。制造了一种带有电子和电气设备的轨道监测车，并在漂移铁路上进行了试验。通过与人工测量数据的比较，认为连续记录钢轨水平、轨距、挠度、速度和振动是合理的。监测车上的数字输出显示器可帮助操作人员真实的实时观察轨道状况。因此，该车厢被认为满足轨道监测的要求。这辆车到目前为止以25公里/小时的速度行驶，有了这个轨道监控系统，它的速度已经提高到40公里/小时。
