Description
Technical Field
The utility model belongs to the sparse field of rail transit vehicle passenger, concretely relates to sparse structure of side door that can overturn and stretch out and draw back of rail transit vehicle has the sparse structure of this side door to and corresponding sparse method, the side evacuation of being particularly useful for novel rail transit field vehicles such as urban railway, urban fast rail transit flees and flees.
Background
By the end of 2018, the mileage of the high-speed railway in China exceeds 3 kilometers, the mileage of urban rail transit exceeds 5000 kilometers, and the railway in China enters a continuous high-speed development stage. Railway passenger transport 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 a passenger emergency evacuation mode on the train is required when the train fails to run.
At present, the high-speed rail motor train unit in China mainly adopts an evacuation ladder arranged on a train, and passengers are evacuated by opening the evacuation ladder by crew members arranged on the train when the passengers are required to be evacuated in emergency.
The common evacuation modes of urban rail transit are two, one is end door evacuation, the other is side door evacuation, and an evacuation platform is arranged in the interval. The end door evacuation is that end doors are arranged in cab at two ends of a train, and passengers are evacuated to a bed surface of a railway through the end doors and a get-off ladder in emergency and then walk to safe regions such as stations. In the side door evacuation, passengers go down to evacuation platforms on two sides through emergency evacuation side doors in emergency, and are quickly evacuated to a safe area through the platform walking to a bed surface. An overhead evacuation platform with the height of 900mm is generally arranged in the underground section, and the distance between the evacuation platform and the equipment limit is generally controlled to be 50-100 mm.
In consideration of urban railways interconnected with national railway motor trains, the speed grade is generally 120-160 km/h, and in order to reduce air resistance and influence on vehicle airtightness and aerodynamic noise, the head train needs to be designed to be streamlined. The streamline vehicle body is difficult to arrange the emergency evacuation door. According to the limit standard of the national railway inter-city motor train unit, the distance between a building and the center of a line is not less than 2200mm, under the condition that the half width of the motor train unit in the city area is 1650mm, if an evacuation platform is arranged, the distance between the evacuation platform and the side part of a vehicle is 550mm at the minimum, and the people easily fall off when evacuating the vehicle under the condition of nervous atmosphere or dim light, so that the safety of passengers is damaged, and the overhead evacuation platform cannot be arranged close to the train according to the conventional mode.
On the lines of the novel rail transit fields such as urban railways and urban fast rail transit or for the purpose of saving engineering investment, under the condition that the modes of train end door evacuation, interval arrangement of evacuation platforms and configuration of evacuation ladders are not feasible, an innovative evacuation mode of rail transit vehicles is very necessary to be found.
