Track gauge measuring device and track detector
The invention provides a track gauge measuring device and a track detector. The gauge measuring device comprises a cross beam, a measuring wheel set and an auxiliary measuring wheel set. A displacement sensor, a connecting guide rod and a connecting assembly are arranged in the cross beam; the connecting assembly comprises a connecting seat, a measuring guide rod and a screw measuring head; the auxiliary measuring wheel set is provided with a universal wave bead, and the screw measuring head abuts against the universal wave bead. According to the invention, the displacement sensor is adopted on the cross beam to detect the track gauge in real time, so that track gauge detection errors can be reduced to make the detection result more accurate, the structure can be simplified, and the weight can be reduced; secondly, the screw measuring head is arranged to abut against the universal wave bead for indirect measurement, so that the cross beam and the auxiliary measuring wheel set can be arranged in a split manner; since the measuring force is adjustable and does not influence the posture, the measuring force and the spring force for ensuring the posture are mutually independent; finally, the position between the auxiliary measuring wheel and the auxiliary walking wheel in the auxiliary measuring wheel set is relatively fixed, so that the measuring point is ensured to be positioned at the true 16mm position in real time.
本发明提供一种轨距测量装置及轨检仪，轨距测量装置包括横梁、测量轮组及辅助测量轮组，横梁内设有位移传感器、连接导杆及连接组件，连接组件包括连接座、测量导杆及螺钉测头，辅助测量轮组设有万向波珠，螺钉测头抵靠万向波珠。本发明通过在横梁上采用一个位移传感器实时地检测轨距，这样不仅可以减少轨距检测误差以使检测结果更加准确，而且可以简化结构和减轻重量；通过设置螺钉测头顶住万向波珠间接测量，从而满足横梁和辅助测量轮组可实现分体设置；由于测量力可调而不会影响姿态，实现测量力和保证姿态的弹簧力互相独立；并且辅助测量轮组中辅助测量轮与辅助走行轮之间的位置相对固定，进而确保测量点实时位于真16mm处。
