本文介绍了一种地面式车轮踏面擦伤检测装置,利用安装在钢轨底部的振动加速度仪测定通过列车的各车轮高、低频振动电平等参数;利用列车检测器和车轮检测器来记录列车种类、车号、轴位等参数。经数据整理后获得各车轮的振动换算电压及检出率值。最后作出擦伤判断,并据此制定镟轮计划。检测列车的速度范围为15～150km/h,最小擦伤尺寸为15×15mm.经一年多试用表明,采用此装置后不但可取消繁重的人工检查,而且可将从擦伤检查至镟轮计划制定的周期从25天缩短到5天。
In this paper, a ground-type wheel tread surface flaw detection device is introduced. The vibrational accelerometer installed at the bottom of the rail is used to measure the high and low frequency vibration levels of each wheel passing through the train. The train detector and wheel detector are used to record the types of trains. Car number, axis and other parameters. The data obtained after the vibration of the wheels converted voltage and the detection rate value. Finally make a bruise to judge, and accordingly draws up the round plan. Detection of the train speed range of 15 ~ 150km / h, minimum scratch size of 15 × 15mm. After more than a year trial shows that the use of this device will not only cancel the heavy manual inspection, but also from the scratch test to the wheel The planning cycle has been reduced from 25 days to 5 days.
