The invention provides a railway fastener base plate settlement volume rapid detection device which comprises a supporting plate, a plurality of telescopic roller mechanisms are arranged on the lower surface of the supporting plate, the bottom ends of the telescopic roller mechanisms are arranged on a steel rail in a rolling mode, the length of the telescopic roller mechanisms can be adjusted in a telescopic mode, and a gradienter and a distance measuring mechanism are arranged on the supporting plate. The distance measuring mechanism comprises a mounting cylinder, a movable distance measuring part and a distance measuring sensor are arranged in an inner cavity of the mounting cylinder, the top end of the movable distance measuring part is slidably connected with the side wall of the inner cavity of the mounting cylinder, the bottom end of the movable distance measuring part can stretch out of the mounting cylinder and make contact with the roadbed slab, and the distance measuring sensor detects the displacement distance of the movable distance measuring part. According to the invention, the displacement distance is measured by the distance measuring sensor through downward movement of the movable distance measuring part, and the settlement value of the upper surface of the steel rail, namely the fastener base plate, can be determined by comparing the displacement distance with previously obtained record data.
本发明提供了一种铁路扣件垫板沉降量快速检测设备,包括支撑板,在支撑板的下表面设置有多组伸缩滚轮机构,伸缩滚轮机构的底端滚动设置在钢轨上,伸缩滚轮机构的长度能伸缩调整,支撑板上设置有水平仪和测距机构,测距机构包括安装筒,安装筒的内腔设置有移动测距部和测距传感器,移动测距部的顶端与安装筒的内腔侧壁滑动连接,移动测距部的底端能伸出安装筒并与道床板接触,测距传感器检测移动测距部的位移距离。本发明通过移动测距部的下移,由测距传感器测量位移距离,与之前得到的备案数据对比,便可确定钢轨上表面、也即扣件垫板的沉降值。
