Railway vehicle and door leaf lower portion locking device thereof
The invention discloses a railway vehicle and a door leaf lower portion locking device thereof. The door leaf lower portion locking device comprises a base, a guide shaft, a sliding block, a rolling wheel, a connecting arm, a driving arm, a limiting piece and a driving mechanism. The guide shaft is positioned on the base; the sliding block is in sliding connection with the guide shaft; the roller is mounted on the sliding block and is used for being assembled with a guide rail of a door leaf; the connecting arm is rotationally connected with the sliding block through a second pin; the driving arm is rotationally connected with the guide shaft through a pin shaft, and the driving arm is rotationally connected with the connecting arm through a first pin; when the driving arm rotates forwards till the center of the first pin is lower than the connecting line of the center of the second pin and the center of the pin shaft, the door leaf is in a plugged state, and the limiting piece limits the connecting arm. The device is compact in structure, small in size and capable of achieving locking of the lower portions of the door leaves, has the advantages of being reliable in locking and small in occupied space, greatly improves the locking safety of a door system, effectively guarantees the personal safety of passengers, and guarantees ordered operation of a train.
本发明公开了一种轨道车辆及其门扇下部锁闭装置包括底座、导向轴、滑块、滚轮、连接臂、驱动臂、限位件和驱动机构；导向轴位于底座上；滑块与导向轴滑动连接；滚轮安装在滑块上，滚轮用于与门扇的导轨装配；连接臂通过第二销钉与滑块转动连接；驱动臂通过销轴与所述导向轴转动连接，驱动臂通过第一销钉与连接臂转动连接；驱动臂正向转动至第一销钉的中心低于第二销钉与销轴的中心的连线时门扇处于塞入状态，且限位件限制连接臂。本发明结构紧凑，体积小巧可实现门扇下部锁闭，具有锁闭可靠，占用空间小的优点，极大提高了门系统锁闭的安全性，有效的保证了乘客的人身安全，保障列车的有序运行。
