The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage floor device mainly structurally comprising a floor support assembly, a corridor floor assembly and a gangway foot plate assembly and is designed into an ultrathin structure so as to fully utilize the limited space at the bottom of a low-floor vehicle, and a floor surface stretches across a through passage and a vehicle body corridor. three rotation points are formed in the center position of a floor and the floor support assembly; the corridor floor support is made of nylon and has mute and wear-resisting effects; the floor support assembly is provided with an angular contact spherical sliding bearing and a spherical bearing; displacement actions such as rotation, side rolling and jolting required by vehicle movement are met; sealing rubber strips are mounted on all separation faces of a spherical bearing installation cavity in the floor supporting assembly, two sealing rubber strips are mounted below a corridor floor cover plate, waterproof sealing can be achieved, and no noise exists. The through passage floor device is simple in structure, the overall height of the floor system is reduced on the premise that the line requirement is met, and the use requirement of a low-floor vehicle model is met.
本发明属于轨道交通设备技术领域,具体涉及一种贯通道地板装置,主体结构包括地板支撑组成、走廊地板组成和渡板组成,设计成超薄结构,以充分利用低地板车辆底部的有限空间,地板面横跨贯通道和车体走廊,地板中心位置和地板支撑组成处共三处旋转点,走廊地板支架为尼龙材质,兼具静音和耐磨功效,地板支撑组成设有角接触球面滑动轴承和球面轴承,满足车辆运动需要的旋转、侧滚、颠簸等位移动作,地板支撑组成中的球面轴承安装腔各分离面安装有密封胶条,走廊地板盖板下安装有两根密封胶条,能够做到防水密封、无噪音;其结构简单,在满足线路要求的前提下,降低了地板系统的总体高度,满足低地板车型的使用需求。
