The invention provides a bogie obstacle detection device, which comprises a fixing frame, a detection circuit and at least one group of detection unit, and is characterized in that the detection unitcomprises an adjusting mechanism and a pull wire; wherein the two fixing frames are oppositely arranged and are both arranged on the bogie, the pull wire is electrically connected with the detection circuit, the two ends of the pull wire are located on the two fixing frames respectively, at least one fixing frame is provided with an adjusting mechanism, and the tension degree of the pull wire is adjusted through the adjusting mechanism. When an obstacle falls into the rail, the obstacle cuts off the stay wire to cause interruption of an electric signal of the stay wire, so that the detection circuit outputs an alarm signal to a traction brake control system of the train to realize braking of the train. Obstacle detection is achieved in the mode that the stay wire is cut off by the obstacle, the detection device is not affected by the train speed any more, the detection device can be suitable for different train speeds, the defects that in an existing mode, many false alarms exist, andadjustment is difficult are effectively overcome, and the use cost of the detection device is reduced.

    本发明提供了一种转向架障碍物检测装置,所述检测装置包括固定架、检测电路和至少一组检测单元,检测单元包括调节机构和拉线;两个固定架相对设置且均设置于转向架上,拉线与检测电路电连接,且拉线的两端分别位于两个固定架上,至少一个所述固定架上设有调节机构,通过调节机构调节拉线的张紧度。当轨道内掉入障碍物时,障碍物会将拉线切断,导致拉线的电信号中断,从而实现检测电路将报警信号输出至列车的牵引制动控制系统实现列车的制动。采用拉线被障碍物切断的形式来实现障碍物的检测,不再受列车速度的影响,可以适用于不同的列车速度,有效解决了现有方式存在误报警特别多,难以调节的短板,降低了检测装置的使用成本。
