Abstract

The invention discloses an emergency passenger evacuation ladder of a rail vehicle. The emergency passenger evacuation ladder aims to solve problems of high quantity of operation steps, long operation duration and poor service safety of an existing movable evacuation ladder. The emergency passenger evacuation ladder of the rail vehicle comprises a mounting frame and a ladder body, and the mounting frame is arranged on the lower side of a floor of a vehicle body; the upper end of the ladder body is movably connected with the bottom of the floor of the vehicle body or the bottom of the mounting frame, and the lower end of the ladder body is locked on the mounting frame by a locking device when the vehicle runs normally, and is unlocked by the locking device when the vehicle is under an emergency condition, so that the ladder body can be driven by an ejecting device to rotate to the lower side of a passenger compartment door; and an emergency control device used for controlling the ejecting device to drive the ladder body to be ejected is mounted in the vehicle, and controls the locking device via an emergency unlocking stay, so that the lower end of the ladder body can be unlocked by the unlocking device. The emergency passenger evacuation ladder has the advantages that passengers in the vehicle can operate the emergency control device to open the emergency passenger evacuation ladder under the emergency condition, and the emergency passenger evacuation ladder is good in safety and high in evacuation efficiency.

Description

technical field [0001] The invention relates to the technical field of rail vehicle manufacturing, in particular to an emergency evacuation ladder for rail vehicle passengers. Background technique [0002] Existing rail vehicle emergency evacuation ladders are stored in the car, taken out from the storage position in an emergency, and placed on the track line at the position of the passenger compartment door. Passengers are evacuated to the track line through the ladder body. This mobile evacuation ladder has many operating steps. Long operation time, poor safety and other problems, prolong the evacuation time when an emergency occurs, and even the evacuation ladder cannot be placed due to the panic of the passengers, which affects the evacuation. Contents of the invention [0003] In order to overcome the disadvantages of the existing mobile evacuation ladders, such as many operation steps, long operation time, and poor safety in use, the present invention aims to provide...
