The invention relates to the technical field of rail transit. The invention further discloses a rail transit guide rail foreign matter detector. An adsorption disc is welded to the top of an inner cavity of a shell I; the side, located on the outer side, of the bottom of the adsorption disc, which is fixedly sleeved with an adsorption piece driving rack, is meshed with a main body structure, so that a direct-current generator generates power and generates current; the output end of the direct-current generator is in signal connection with a guide rail, so as to reduce the current and transmitthe current to a track; the input end of a detection sending device is in signal connection with the guide rail; detection sending devices in a plurality of same devices at other positions can receivethe current conducted by the track and detect current intensity; whether the railway state is normal or not can be known through a manual means according to a current decreasing value and gradient change, the approximate distance of a dangerous situation can be calculated according to the gradient of an abnormal current value, braking can be conducted in advance, the accident that a train cannotbe braked in time and derail is caused due to the fact that the train cannot be foreseen in advance is avoided, and the safety of railway transportation is improved.

    本发明涉及轨道交通技术领域,且公开了一种轨道交通导轨异物检测器,通过外壳Ⅰ内腔的顶部焊接有吸附盘,吸附盘底部位于外侧的位置上固定套接有吸附片主动齿条的一侧啮合有主体结构,从而使直流发电机发电并产生电流,通过直流发电机的输出端与导轨信号连接降电流传输至铁轨。通过检测发送装置的输入端与导轨信号连接,其他位置多个相同装置中的检测发送装置会接收到铁轨传导过来的电流并检测出电流强度,通过人工对电流递减值和梯度变化可以了解到铁路状态是否正常,并且对于电流值出现异常的梯度可以推算出险情的大致距离,可提前进行制动,避免出现火车无法提前预知导致火车刹车不及导致脱轨的事故,提高了铁路运输的安全性。
