Abstract

The invention relates to a ramp emergency evacuation door, including a door frame and a door page, wherein the low part of thedoor page is connected with the door frame through a linkage mechanism; the upper part of the door frame is provide with a recovery device; one end of the recycling device is connected to the upper end of the door page through a sling strap, and the other end of the recycling device is connected with a recycling box device through a recycling belt, and a transition pedal fixed to the linkage mechanism is arranged on the inner side of the door page; the transition pedalis provided with a fixing plate located on the inner side of the door frame, and two movable plates turned out outward; and a fixed pedal is arranged on the inner side of a fixed top plate. In the ramp emergency evacuation door, the door page is turned down to the rail surface, and the transition pedal assembly is unfolded through a connecting rod hinge mechanism and overlapped on the door page passage to form a longer evacuation passage. The ramp emergency evacuation door solves the problem that the existing evacuation door has many complicated parts and high cost, and provides a new solutionfor realizing quick rescue.

Description

technical field [0001] The invention relates to an emergency evacuation door for rail vehicles, and is especially suitable for urban rail vehicles. Background technique [0002] In recent years, subway vehicles have been widely used in many cities. Each city will have different influence factors when constructing lines. The lines can be tunnels, elevated or on the ground. Some lines have been modified to build evacuation platforms, and some lines No evacuation platform is built, and according to different line conditions, reasonable and convenient emergency evacuation methods need to be set up on the corresponding rail vehicles to cope with the rapid evacuation of passengers in emergency situations. Emergency evacuation methods mainly include: vehicle side evacuation (evacuation through the side door of the passenger compartment); emergency evacuation from the front of the vehicle; emergency evacuation from the rear of the vehicle. [0003] After searching, it was found tha...
