The invention discloses a track geometric parameter measuring instrument using a double-galvanometer laser scanning module, which is mounted on a movable track inspection trolley and is internally provided with a data acquisition control panel. The data acquisition control panel is connected with the angle sensor, the linear displacement sensor, the mileage sensor and the double-galvanometer laser scanning module. Sensors for detecting mileage, track gauge, angle and the like, a double-galvanometer laser scanning module and a data acquisition control panel are integrated on the hand-push type track detection trolley. Based on the principle of relative measurement, the track geometric parameter measuring instrument can detect track geometric smoothness evaluation parameters such as mileage, track gauge, levelness (superelevation), triangular pit, track direction and height of a track in real time, the track geometric parameter measuring instrument uses the double-galvanometer laser scanning module to measure relative position coordinates, the measuring precision is high, and the measuring speed is high.

    本发明公开了一种使用双振镜激光扫描模块的轨道几何参数测量仪,该轨道几何参数测量仪安装在一个可移动的轨检小车上,该轨道几何参数测量仪内设置有数据采集控制板,数据采集控制板分别与角度传感器、直线位移传感器、里程传感器和双振镜激光扫描模块相连。手推式轨检小车上集成检测里程、轨距、角度等传感器以及双振镜激光扫描模块和数据采集控制板。轨道几何参数测量仪基于相对测量的原理,可实时检测轨道的里程、轨距、水平(超高)、三角坑、轨向和高低等轨道几何平顺性评价参数,该轨道几何参数测量仪使用双振镜激光扫描模块测量相对位置坐标,测量精度较高,测量速度快。
