The invention relates to the technical field of train emergency ramps, in particular to an electric recovery ramp system which comprises a box body, a rotating combination, a braking assembly and a clamping assembly, the box body is installed on a frame body and provided with a wire outlet hole, the rotating combination comprises a lead screw, a first rotating part, a second rotating part and a first rope body, and the lead screw is rotatably installed on the box body; the first rotating part and the second rotating part are both in threaded connection with the lead screw, one end of the first rope body is wound on the first rotating part, the other end of the first rope body penetrates through the wire outlet hole and is connected with a pedal, the braking assembly comprises a braking part, and the braking part abuts against or is separated from the second rotating part. When the pedal is turned downwards and pulls the first rope body, the first rotating piece rotates on the lead screw and is connected with the second rotating piece, the rotating speed of the second rotating piece is reduced through the braking piece, the turning-down speed of the pedal is reduced, and the advantage of the buffering function is achieved.

    本申请涉及列车应急坡道技术领域,更具体地涉及一种电动回收坡道系统,包括:盒体、转动组合、制动组件和夹紧组件,盒体安装在架体上,盒体具有出线孔,转动组合包括丝杆、第一转动件、第二转动件和第一绳体,丝杆转动安装在盒体上,第一转动件和第二转动件均与丝杆螺纹连接,第一绳体的一端卷绕在第一转动件上,另一端穿过出线孔并与一踏板连接,制动组件包括制动件,制动件与第二转动件抵靠或分离,本发明通过坡道展开时夹紧组件夹紧丝杆,当踏板下翻并拉动第一绳体,第一转动件在丝杆上转动并与第二转动件连接,则制动件将降低第二转动件的转速,并导致踏板下翻速度降低,实现带缓冲功能的优势。
