A platform for research: civil engineering, architecture and urbanism
The invention discloses an urban rail transit emergency safety door, and relates to the technical field of emergency safety door devices. The safety door comprises an upper door frame and a lower doorframe, a first sliding groove is formed in an inner cavity of the upper door frame, a rotating shaft is coaxially and rotatably connected to the front portion of a spring telescopic rod, a third gear, a ratchet wheel, a rolling wheel and a pressing block are coaxially and fixedly connected to the outer portion of the rotating shaft in sequence from back to front, the outer wall of the rolling wheel is wound and fixedly connected with a steel rope, the end of the steel rope away from the rolling wheel is fixedly connected with a counterweight, when a passenger is clamped, a first door body anda second door body can rapidly stop closing and be opened, the passenger is prevented from being clamped, safety is improved, when encountering an emergency, the safety door can be opened quickly toavoid the occurrence of safety accidents in the emergency, and crowds can be conveniently and quickly evacuated.
本发明公开了城市轨道交通应急安全门,本发明涉及应急安全门装置技术领域。该城市轨道交通应急安全门,包括上门框与下门框,上门框内腔开设有第一滑槽,弹簧伸缩杆前部同轴转动连接有转动轴,转动轴外部从后至前依次同轴固定连接有第三齿轮、棘轮、卷轮与按压块,卷轮外表壁缠绕固定连接有钢绳索,钢绳索远离卷轮的一端固定连接有配重块,本发明能够在当乘客被夹到时第一门体与第二门体能够迅速的停止闭合并进行打开,避免夹伤乘客,提高安全性,且当遇到紧急情况时安全门能够快速的打开,避免紧急情况下安全事故的发生,便于快速疏散人群。
