Description
Technical Field
The invention belongs to the field of passenger evacuation of rail transit vehicles, and particularly relates to a turnover telescopic side door evacuation structure of a rail transit vehicle, the rail transit vehicle with the side door evacuation structure and a corresponding evacuation method, which are particularly suitable for side evacuation escape of vehicles in the novel rail transit fields such as urban railways, urban rapid rail transit and the like.
Background
By the end of 2018, the mileage of the high-speed railway in China exceeds 3 ten thousand kilometers, the mileage of urban rail transit exceeds 5000 kilometers, and the railway in China enters a continuous high-speed development stage. Railway passenger transportation has the characteristics of large passenger capacity, high safety and good reliability, but the accident of railway vehicle shutdown caused by natural disasters, human errors or vehicle faults also happens occasionally, so that an emergency evacuation mode of passengers on a train is required when the train fails to run.
At present, high-speed rail motor train units in China are mainly provided with evacuation ladders on trains, and passengers are evacuated by opening the evacuation ladders by crews equipped on the trains when passengers are evacuated in emergency.
Two common evacuation modes for urban rail transit are provided, one is end door evacuation and the other is side door evacuation, and evacuation platforms are arranged in the sections. The end door evacuation is to arrange end doors at cabs at two ends of a train, evacuate passengers to the ballast bed surface through the end doors and the lower ladder in emergency, and walk to the safety areas such as stations. The side door evacuation is to evacuate passengers to evacuation platforms at two sides through the emergency evacuation side door under emergency conditions, and to evacuate to a safe area rapidly through platform walking to the ballast bed surface. An overhead evacuation platform with the height of 900mm is generally arranged in an underground zone, and the distance between the evacuation platform and equipment limit is generally controlled to be 50-100 mm.
In the urban railway which is considered to be interconnected and communicated with the national iron motor train unit, the speed grade is generally 120-160 km/h, and in order to reduce air resistance and influence on vehicle air tightness and aerodynamic noise, the head vehicle is required to be designed into a streamline shape. And the streamline car body is difficult to arrange the emergency evacuation door. According to national railway inter-city motor train unit limit standards, the distance between a building and the center of a line is not smaller than 2200mm, when the half width of a train body of a city motor train unit is 1650mm, if an evacuation platform is arranged, the distance between the evacuation platform and the side of a vehicle is 550mm at the minimum, people are easy to drop during evacuation under the condition of tense atmosphere or dim light, and the safety of passengers is endangered, so that the overhead evacuation platform cannot be arranged adjacent to the train according to a conventional mode.
On the lines of novel rail transit fields such as urban railways and urban rapid rail transit, or for the purpose of saving engineering investment, when the modes of evacuation platforms and configuration evacuation ladders are not feasible in train end door evacuation and section setting, an innovative rail transit vehicle evacuation mode is very necessary to be sought.
