Description
Technical field
The invention belongs to field of track traffic, and in particular to a kind of big aperture egress door of rail vehicle and drivers' cab.
Background technology
Currently, external Tokyo, London, New York, Moscow metro vehicle train front end be arranged side, in set egress door system
System, railcar front screen are divided into three or two regions.Domestic railcar evacuation door system is set in having with transparent
Window type, in set without transparency window house type, side band transparency window house type, general emergency evacuation ramp is about by width only
460mm is only capable of through a passenger, and drivers' cab front end front screen is divided into three or two regions, influences drivers' cab
Interior permeability and the visual field also has a certain impact to appearance and modeling, and is unfavorable for the rapid evacuation of in emergency circumstances passenger.
With the development of rail traffic, evacuation door system is higher and higher to the requirement of big evacuation capacity both at home and abroad, with urgent
In the case of, passenger is quickly evacuated as possible.Meanwhile being also more fully apparent to driver's viewing from inside, the more preferable direction of lighting conditions is developed.
At tunnel or overhead operation, part or all fronts are not arranged in the case of the formula evacuation platform of side train, and train front end must be provided with dredging
Door is dissipated, meanwhile, the setting of front end egress door must assure that the leakproofness between egress door and train body, existing evacuation door system
It is general only by the sealant between seal frame and egress door come waterproof, windproof, effect is often not satisfactory, and for curved surface
For the egress door of structure, door leaf area is bigger, and sealing performance is more difficult to guarantee.In addition, the installation of egress door needs high peace
Precision is filled, to ensure under emergency, the smooth opening of energy farthest saves escape time.Evacuation capacity is improved, is pacified
Larger-sized egress door is filled to be necessary, but the size of egress door is bigger, installation difficulty is higher, how to ensure high installation
While precision, egress door is connected and a problem urgently to be resolved hurrily with car body.
