The invention provides a full-width pneumatic emergency safety device for a B-type subway vehicle, and belongs to the technical field of rail safety. The full-width door leaf capable of being turned upwards is arranged on the vehicle head of the vehicle, the pneumatic door opening structure and the evacuation ramp are arranged on the vehicle body floor, automatic or manual opening of the full-width door leaf is achieved through the pneumatic door opening structure, the view field is better, and external environment information can be obtained conveniently during evacuation; the air springs and the buffers of the evacuation ramp are arranged at the bottoms of the pedals, thrust and buffering can be provided for unfolding of the evacuation ramp, the air springs and the buffers are hidden under the pedals, space utilization is more reasonable, and the problem that the width of the whole structure is too large due to the fact that an existing structure occupies the space on the two sides of the pedals is solved; the air spring buffer device is more suitable for being used on a vehicle with the limited width, the using limitation is smaller, the problem that the evacuation trafficability is affected due to the fact that the air spring and the buffer protrude out of the pedal is solved, safety is improved, and emergency evacuation is facilitated.

    本发明提供了一种B型地铁车辆全宽式气动应急安全装置,属于轨道安全的技术领域。本发明通过在车辆的车头设置可上翻的全宽门扇,并通过在车体地板上设置气动开门结构和疏散坡道,通过气动开门结构实现对全宽门扇的自动或手动打开,视野更好,利于疏散时获取外界环境信息,另外,将疏散坡道的空气弹簧和缓冲器均设置于踏板的底部,既能为疏散坡道的展开提供推力以及缓冲,还实现了空气弹簧和缓冲器在踏板下的隐藏,空间利用更合理,避免了现有结构占用踏板两侧空间而导致整体结构宽度过大的问题,更适用于在宽度有限的车辆上使用,使用限制更小,且也避免了空气弹簧和缓冲器突出于踏板上而影响疏散通过性的问题,提高了安全性,利于应急疏散。
