The invention belongs to the technical field of rail transit equipment, and particularly relates to a locking and self-clamping device for a through passage gangway foot plate, wherein the locking and self-clamping device structurally comprises a connecting rod, locking tension springs, groove-shaped locks, limiting pull rods, pull rings, mounting holes and nylon sleeves. Rapid installation and disassembly of the gangway foot plate can be realized; after the pull rings are pulled to the sides, provided with protrusions, of the limiting pull rods to be limited simultaneously or independently, the protrusions of the limiting pull rod are clamped at the ends of the mounting grooves, the limiting pull rods are in a clamping rotation stopping state, the gangway foot plate is unlocked, and when one pull ring is pulled independently, the other pull ring needs to be subjected to the same operation, and then the gangway foot plate can be unlocked; the locking and self-clamping device is simple in structure, can improve the gangway foot plate mounting and dismounting efficiency and safety, and meets the relative change requirements of stretching, compression, side rolling, nodding, head raising limit displacement curves and the like of two carriages when a train runs at a high speed.

    本发明属于轨道交通设备技术领域,具体涉及一种贯通道渡板锁闭自卡装置,主体结构包括连接杆、锁闭拉簧、槽形锁具、限位拉杆、拉环、安装孔和尼龙套,能够实现渡板的快速安装与拆卸,同时或单独向限位拉杆有凸起的一侧拉拽拉环到限位后,使限位拉杆的凸起卡在安装槽的端部,使得限位拉杆处于卡止转状态,渡板解锁,当单独拉拽一个拉环时,需要对另一个拉环也进行同样的操作,才能使渡板解锁;其结构简单,能够提高渡板安拆效率和安全性,满足列车高速运行时的两节车厢拉伸、压缩、侧滚、点头、抬头极限位移曲线等相对变化要求。
