Urban rail transit vehicle and folding pedal assembly for emergency escape of urban rail transit vehicle

Abstract

The invention discloses an urban rail transit vehicle and a folding pedal assembly for emergency escape of the urban rail transit vehicle. The urban rail transit vehicle comprises a vehicle body and avehicle head, the vehicle head is arranged on one side of the vehicle body, an escape exit is formed in the middle of the vehicle head, and an escape door is arranged in the escape exit; and a hingeis arranged on the outer side of the bottom of the escape door, and a pedal assembly is arranged on the inner side of the escape door. According to the urban rail transit vehicle and the folding pedalassembly for emergency escape thereof, an escape evacuation door and the folding pedal assembly are arranged to be of an integrated structure, the evacuation door is directly rotated downwards to thegrounding position, the evacuation door serves as a supporting framework of the folding pedal, the escape channel opening step is simplified, operation is easy and convenient, the number of parts ofan escape mechanism is reduced, the problem of potential safety hazards caused by the fact that an existing escape door cannot be supported in emergency is solved, the structural reliability is higher, meanwhile, the plate body plane angle of the pedal can be adjusted according to the supporting height of the escape door so as to meet the bearing requirements of different escape positions, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit facilities, and in particular relates to an urban rail transit vehicle and a folding pedal assembly for emergency escape thereof. Background technique [0002] Urban rail transit refers to public transportation facilities with fixed lines, fixed tracks, and transportation vehicles and service facilities. The construction and development of urban rail transit is conducive to improving the efficiency of citizens' travel, saving time and improving the quality of life. During the operation of urban rail transit vehicles, in order to ensure the safety of passengers, it is usually necessary to install emergency escape equipment. The evacuation door is a kind of escape equipment installed on the subway or urban rail train. In case of emergency or accident, the evacuation door is opened and Grounding pedals are set up to form evacuation passages, and escape doors are generally set at the head of the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an urban rail transit vehicle and its folding pedal assembly for emergency escape in order to solve the above problems. The escape door and the folding pedal structure are integrated, and the evacuation door is directly rotated downward until it touches the ground. Position, use the evacuation door as the supporting frame of the folding pedal, simplify the opening steps of the escape passage, easy to operate, and reduce the number of parts of the escape mechanism, solve the safety hazard caused by the inability of the escape door to be propped up in an emergency, and the structural reliability is higher. Strong practicability, see below for details
