The invention relates to the technical field of rail trains, in particular to an obstacle detection device with an adjustable trigger threshold value, a bogie and a rail vehicle. The obstacle detection device comprises a frame, a plate spring and a sensor. The plate spring comprises a fixed plate and a movable plate, and the fixed plate is fixedly connected with the frame; the sensor comprises a first induction piece and a second induction piece, the first induction piece is installed on the side, facing the frame, of a movable plate of the plate spring, and the second induction piece is installed at the position, corresponding to the first induction piece, of the frame. An adjusting gasket is arranged between the first induction piece and the plate spring movable plate and used for adjusting the relative position between the first induction piece and the second induction piece. The obstacle detection device solves the problem of missed triggering or false triggering caused by the change of the triggering force value of the sensor when the distance between the detection beam and the rail surface is different, the manufacturing difficulty is greatly reduced, and the production cost is saved.

    本发明涉及轨道列车技术领域,尤其涉及一种可调触发阈值的障碍物检测装置、转向架及轨道车辆。障碍物检测装置包括:框架、板弹簧和传感器;所述板弹簧包括固定板和活动板,所述固定板与所述框架固定连接;所述传感器包括第一感应件和第二感应件,所述第一感应件安装在所述板弹簧的活动板朝向所述框架的一侧,所述第二感应件安装在所述框架上与所述第一感应件相对应的位置,所述第一感应件和所述板弹簧活动板之间设置调整垫片用于调整第一感应件和第二感应件之间的相对位置。该障碍物检测装置解决了检测梁距离轨面不同高度时传感器触发力值发生变化造成漏触发或误触发的问题,而且大大降低了制造难度,节省了生产成本。
