The invention discloses an emergency evacuation ramp device capable of being automatically released. The emergency evacuation ramp device comprises a first-stage ramp hinged to a fixed frame and a second-stage ramp hinged to the first-stage ramp. The first-stage ramp and the second-stage ramp are respectively provided with at least two hinged pedals, and the two pedals located in the middle are movable pedals. A linkage rod system is connected between the ends, away from each other, of the two movable pedals and the fixed frame, and the linkage rod system drives the first-stage ramp and the second-stage ramp to be unfolded or folded under the action of the energy storage device. One end of the rotating mechanism is connected with the linkage rod system, the other end of the rotating mechanism is connected with the movable pedals, and the linkage rod system can drive the two movable pedals to turn over; an energy storage device is connected between the first-stage ramp and the vehicle body; and the first-stage ramp is connected with an inhaul cable. Compression of the space in the length direction of the evacuation ramp in the recovery state is achieved through the two folded ramps and the turnover movable pedal, and one-key automatic unfolding of the two folded ramps is achieved through the linkage rod system and a related gear transmission pair of the linkage rod system.

    本发明公开了一种可自动释放的紧急疏散坡道装置,包括铰接于固定框架上的一级坡道,与一级坡道铰接的二级坡道;一级坡道、二级坡道分别设有至少两个铰接的踏板,位于中间的两个踏板为活动踏板;两个活动踏板相互远离的端部与固定框架之间连接有联动杆系,联动杆系在储能装置的作用下带动一级坡道和二级坡道展开或折叠;还包括转动机构,转动机构的一端与联动杆系连接,另一端与活动踏板连接,联动杆系可带动两个活动踏板翻转;一级坡道与车体之间连接有储能装置;一级坡道上连接有拉索。本发明通过两折叠的坡道以及可翻转的活动踏板实现疏散坡道回收状态下车长方向空间的压缩,并通过联动杆系及其相关的齿轮传动副实现两折叠坡道一键自动展开。
