The invention relates to the field of track measurement, and discloses a straddle vehicle track geometric detection system which comprises a frame and a bogie, a detection frame is mounted on the frame and comprises upper clamping plates and lower clamping plates which are symmetrically arranged on the frame, four corners of the upper clamping plates and four corners of the lower clamping plates are fixed on the frame through screws, and a cross beam is mounted between the two upper clamping plates. A data acquisition system, an inertia detection unit and a 2D laser sensor are installed on the cross beam, a detection rod is installed on the lower clamping plate in a suspended mode, and the 2D laser sensor for detecting the guide wheel and the stabilizing wheel is sequentially installed on the side wall of the side, close to the track, of the detection rod from top to bottom. The inertia detection unit and the 2D laser sensors are installed on the detection frame, the positions of the walking wheels, the stabilizing wheels and the guide wheels can be detected in real time when the bogie travels along the track, the irregularity state of the track is calculated, and meanwhile the detection frame has enough strength and rigidity, is light in weight and convenient to use and popularize. And fuzzy data generated by mechanical vibration can be effectively avoided.

    本发明涉及轨道测量领域,公开了跨坐车轨道几何检测系统,包括车架和转向架,车架上安装有检测架,检测架包括对称设置在车架上的上夹板和下夹板,上夹板四角和下夹板四角通过螺杆固定在车架上,两块上夹板之间安装有横梁,横梁上安装有数据采集系统、惯性检测单元和2D激光传感器,下夹板上悬挂安装有检测杆,检测杆靠近轨道一侧的侧壁上从上往下依次安装有检测导向轮和稳定轮的2D激光传感器。本发明通过在检测架上安装惯性检测单元和多个2D激光传感器,可实时检测转向架沿轨道行进时走行轮、稳定轮以及导向轮的位置,并计算出轨道的不平顺状态,同时检测架具有足够的强度和刚度,且质量轻,能有效避免因机械振动产生的模糊数据。
