The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage gangway foot plate device which structurally comprises a gangway foot plate body, abrasion parts, mounting grooves, a locking self-clamping mechanism, an observation opening and an observation opening cover plate, and the abrasion parts are arranged on the two longitudinal side edges of the lower surface of the gangway foot plate body; the mounting groove is arranged on the longitudinal central axis of the lower surface of the gangway foot plate body; the locking self-clamping mechanism is arranged in the mounting groove; the observation opening is formed in the upper portion of the locking self-clamping mechanism; the observation opening cover plate is arranged on the observation opening, and the gangway foot plate body can be rapidly mounted and dismounted through the locking self-clamping mechanism; pull rings are pulled to the sides, provided with protrusions, of limiting pull rods to be limited simultaneously or independently, so the protrusions of the limiting pull rods are clamped at the end parts of the mounting grooves, at the moment, the limiting pull rods are in a clamping state, the gangway foot plate is unlocked, and when one pull ring is independently pulled, the other pull ring also needs to be subjected to the same operation, so that the gangway foot plate can be unlocked.
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装置,主体结构包括渡板体、磨耗件、安装槽、锁闭自卡机构、观察口和观察口盖板,渡板体的下表面纵向两侧边沿设置有磨耗件,渡板体的下表面纵向中轴线上设置有安装槽,安装槽中设置有锁闭自卡机构,锁闭自卡机构的上方设置有观察口,观察口上设置有观察口盖板,使用锁闭自卡机构实现渡板体的快速安装与拆卸,同时或单独向限位拉杆有凸起的一侧拽拉拉环到限位后,使限位拉杆的凸起卡在安装槽的端部,此时,限位拉杆处于卡止状态,渡板解锁,当单独拽拉一个拉环时,需要对另一个拉环也进行同样的操作,才能使渡板解锁。
