Description

  In particular, the present invention relates to an evacuation device provided in a rail vehicle that travels along a track laid on an elevated and a method of fixing the evacuation device to the rail vehicle when the evacuation device is used.

  When a serious failure or a fire occurs in a rail vehicle that runs along a rail laid on an overpass, it is necessary to evacuate passengers from the vehicle. If the vehicle is stopped at the station, it is possible to evacuate to a boarding / alighting platform attached to the station. However, if the above-mentioned event occurs while traveling between a station and a railroad vehicle that is traveling on a rail laid on an overpass and does not have a structure that can be used for evacuation, such as a platform, Passengers must be safely evacuated from the parked vehicle.

  When traveling on an adjacent double track elevated track, the rescue formation vehicle is stopped in parallel with the formation vehicle on the opposite elevation track, and the side sliding doors facing the formation vehicle and the relief formation vehicle are opened. Thereafter, a method of evacuating passengers from the trained vehicle to the rescue train by constructing an evacuation passage (ladder) between the side sliding doors of both vehicles is being studied. In addition, if it is on a single line elevated, the rescue formation vehicle is stopped in series with the formation vehicle, and an evacuation passage (ladder) is constructed from the rear vehicle of the formation vehicle to the leading vehicle of the relief formation vehicle, A method to guide evacuation is being studied.

  In the event of a major hindrance to a substation facility that supplies power necessary for the operation of rail vehicles due to a large-scale earthquake, etc., multiple rail vehicles traveling on the overpass will stop, making it impossible to operate rescue trains . For this reason, the evacuation apparatus which a passenger can evacuate to the ground safely from the formation vehicle by the evacuation apparatus with which the formation vehicle is provided without depending on the rescue formation vehicle has been devised.

  This evacuation device is provided in the vicinity of the side entrance of the rail vehicle, and is configured to expand from the side sliding door of the rail vehicle in the width direction of the rail vehicle to form a cantilever, It consists of a slope part continuous to the part. The slope portion expands along the longitudinal direction of the rail vehicle, and its tip end abuts on the ground to form an evacuation route from the rail vehicle to the ground via the cantilever and the slope portion. The passenger exits from the side entrance of the rail vehicle to the part that has expanded like a cantilever, and then slides down the slope to reach the ground. The configuration of this evacuation device is shown in Patent Document 1, for example.

  The evacuation device is installed in the vicinity of a specific side sliding door of the rail vehicle. For this reason, if the stop position at the time of a rail vehicle stopping on an elevated track at the time of emergency is determined, the position on the ground of the tip part of the slope which constitutes an evacuation device will be determined non-selectively. If the tip of the slope portion comes into contact with a car parked on the ground or a side wall or roof of a structure or the like, the safety of passengers who slide down the slope portion may be impaired.
