Technical field
The utility model is related to a kind of intercity administrative region of a city vehicle, particularly to a kind of be arranged on intercity administrative region of a city car promptly dredge
Scattered door gear, belongs to rail vehicle manufacturing technology field.
Background technology
In the drivers' cab headstock position of the intercity administrative region of a city car such as subway, it is generally provided with emergency evacuation equipment, because subway
Operating line mostly is overpass, tunnel, if overpass, tunnel do not possess side formula and evacuate during condition it is necessary to two ends headstock sets
Put emergency evacuation equipment, make passenger be dispersed into ground from headstock and withdraw.
Emergency evacuation equipment typically from can the door body that open upwards or to both sides and the ramp two parts spreading out downwards form,
May also be employed turning over detrainment device under integral type.In the state of normal operation, emergency evacuation equipment does not use and is in locking
State.When there is the emergency such as fire, fault in overpass, tunnel in urban rail administrative region of a city vehicle, can manual unlocking this is urgent
Detrainment device, for the emergency evacuation of occupant.
For meeting the requirement that domestic regional economy is fast-developing and group of cities emergence is to inter-city rail transit, more speed level
The intercity administrative region of a city car being applied to city to suburbs of (140 kilometers of speed per hour) rises, and it had both needed EMU and has continued
The ability of high-speed cruising, has the start-stop ability as subway again.The operating line of intercity administrative region of a city car is also overpass, underground tunnel
Road etc., so being the security ensureing passenger evacuation in emergency circumstances, intercity administrative region of a city car is also required to headstock setting emergency evacuation
Device.
Existing railcar, running speed per hour is about 80-120 kilometer, and when vehicle is run with 140 kilometers, head car
Detrainment device needs to bear larger pressure, and the detrainment device of trailer then needs to bear larger pulling force, particularly when vehicle is transported
Went tunnel and intersection when, moment can produce larger aerodynamic loading, due to run speed per hour raising, urgent to drivers' cab front end
Bear load-carrying ability, locking security and air-tightness etc. of egress door have higher requirement.So needing design a kind of complete
New headstock emergency evacuation equipment, not only will meet the evacuation of in emergency circumstances passengers inside the car it is often more important that how will solve
Improve and bear a series of technological difficulties such as load-carrying ability, locking security and air-tightness, to adapt to 140 kilometers of intercity administrative region of a city overall height
The requirement of speed operation.
