The invention discloses an emergency escape evacuation ramp device of an urban rail transit vehicle, which comprises a mounting shell, a folding escape pedal, a puncture mechanism, a pull rope supporting mechanism and an intelligent controller, and is characterized in that the mounting shell is mounted on a fire escape window of the urban rail transit vehicle; the mounting shell comprises a protective door rotationally connected to the rear side of the mounting shell, the protective door is used for protection work and preventing passengers from opening the protective door to cause accidents, and the protective door is driven by forward rotation and reverse rotation of a servo motor, meshing of a first gear with an annular gear and a second gear and meshing of two second bevel gears with two first bevel gears. When the two steel wire ropes are wound, the two steel wire ropes can be driven to rotate reversely and forwardly, so that the two steel wire ropes can be unwound and wound, and meanwhile, the two conveying belts can be driven to rotate forwardly and reversely, so that a plurality of first bearing seats can be shifted, and the two steel wire ropes can be wound on the outer wall of the collecting rod in order in the unwinding and winding processes; and the phenomenon of staggering is avoided.

    本发明公开一种城市轨道交通车辆的应急逃生疏散坡道装置,包括:安装外壳,折叠逃生踏板,穿刺机构,拉绳支撑机构和智能控制器,所述安装外壳安装在城市轨道交通车辆的消防逃生窗口上,所述安装外壳包括转动连接在安装外壳后侧的防护门,所述防护门用于防护工作,避免乘客打开,造成事故产生,通过伺服电机的正转和反转,以及通过第一齿轮分别与环形齿轮和第二齿轮啮合、两个第二锥齿轮与两个第一锥齿轮啮合,就会带动收集杆反转和正转,从而就可以对两个钢丝绳进行放绳+和收绳工作,同时,也会带动两个传送带正转和反转,使得多个第一轴承座可以拨动,使得两个钢丝绳在放绳和收绳的过程中,可以有序的缠绕在收集杆的外壁上,避免出现错落的现象。
