The invention provides an escape ladder, a rail vehicle and a rail transit system. The escape ladder comprises a fixed rod, a telescopic rod and a plurality of pedals, wherein the length of the telescopic rod is variable, a first end of the telescopic rod is rotatably connected with the fixed rod, each pedal is rotationally connected with a second end of the corresponding fixed rod and a second end of the corresponding telescopic rod, the fixing rod, the telescopic rod and the pedals can rotate to a state that the fixing rod, the telescopic rod and the pedals are right opposite to one another,and at the moment, projection of a rotating shaft, rotationally connected with the telescopic rod, of the pedal on a longitudinal vertical plane coincides with projection of the fixed rod on the longitudinal vertical plane. The escape ladder is advantaged in that compared with the prior art, the escape ladder for the railway vehicle is simple in structure and can be switched to be in a small-sizestate, so when the escape ladder is placed in the railway vehicle, the occupied space is greatly reduced, and negative influence on the in-vehicle impression is reduced.
本发明提供了一种逃生梯、轨道车辆和轨道交通系统,所述逃生梯包括:固定杆;伸缩杆,所述伸缩杆的长度可变,所述伸缩杆的第一端与所述固定杆转动连接;多个踏板,每个所述踏板分别与所述固定杆和所述伸缩杆的第二端转动连接;所述固定杆、所述伸缩杆和所述踏板可转动至三者正对状态,此时所述踏板与所述伸缩杆转动连接的转动轴在纵向竖直平面上的投影与所述固定杆在纵向竖直平面上的投影重合。本发明提供的用于轨道车辆的逃生梯,结构简单,且可切换至体积较小的状态,使得所述逃生梯放置在所述轨道车辆内时,大大减少占据的空间,并减轻对车内观感的负面影响。
