The invention discloses an obstacle detection device, a bogie and a railway vehicle. The obstacle detection device comprises a detection cross beam and a detection mechanism, and the detection cross beam is used for receiving impact from an obstacle; the detection mechanism comprises a box body and a detection assembly, the box body is used for installing the detection assembly, the detection assembly at least comprises a plate spring, a pre-pressing piece and a travel switch, the pre-pressing piece is used for pre-compressing the plate spring, and the travel switch is used for detecting the movement of the detection cross beam and transmitting a signal to a controller; therefore, the rail vehicle is controlled to be braked. Compared with the prior art, the detection assembly disclosed by the invention is internally provided with the pre-pressing piece, and the pre-pressing piece can pre-compress the plate spring, so that false triggering caused by wheel track vibration can be avoided, and the reliability of the obstacle detection device can be effectively improved; and the probability of emergency braking when the railway vehicle is not in contact with the obstacle is reduced.

    本发明公开了一种障碍物检测装置、转向架和轨道车辆,其中障碍物检测装置包括检测横梁和检测机构,其中检测横梁用于接收来自障碍物的冲击;检测机构包括箱体和检测组件,所述箱体用于安装所述检测组件,所述检测组件至少包括板弹簧、预压件和行程开关,所述预压件用于对所述板弹簧进行预压缩,所述行程开关用于检测所述检测横梁的运动并将信号传输给控制器,以控制所述轨道车辆进行刹车制动。和现有技术相比,由于本发明所公开的检测组件中设置了预压件,预压件可对板弹簧进行预压缩,因此可以避免轮轨振动引起的误触发,从而可以有效提升障碍物检测装置的可靠性,降低轨道车辆在未接触障碍物时出现紧急制动现象的几率。
