Through type cab emergency door

Abstract

The invention discloses a through type cab emergency door. A pair of cab emergency end doors capable of being opened oppositely outwards is arranged in the center of the front end of a cab; door lock devices are arranged at the inner sides of the cab emergency end doors; the door lock device comprise a door lock, and a lock groove and a lock chain groove formed at the corresponding positions of two door leaves respectively; a lock chain, the movable end of which is matched with the lock chain groove, is fixed in the lock groove; and a ground arc cab apron extended forwards is arranged at the front end of the cab. When a train is temporarily enlarged, the through type cab emergency door structure of a head vehicle is opened and butted with a through passage of a middle vehicle, or the through type cab emergency door structures of two head vehicles are connected, so that the purposes of transferring or evacuating passengers and temporarily improving the delivery capacity are fulfilled; and if a sudden accident (particularly a subway vehicle catches a fire in a tunnel and the like) happens in the transport process, the through emergency evacuation structure is provided, and the passengers in the fault train can be quickly evacuated to a rescue train, so that life and wealth safety of the passengers is ensured.

Description

technical field [0001] The invention relates to an end structure of a driver's cab of a subway vehicle or other rail vehicles, relates to a structure of an end door and a passageway of a driver's cab of a subway vehicle or other rail vehicles, and belongs to the field of mechanical manufacturing. Background technique [0002] With the rapid development of rail transit, in order to improve the transportation capacity of urban subway vehicles during rush hours, or other rail vehicles to meet the surge in passenger flow during holidays in my country, especially during the Spring Festival, how to flexibly improve transportation capacity is the effort of operating companies and manufacturers. topics to explore. It is a cost-effective measure to temporarily increase the transportation capacity by temporarily expanding the number of trains and temporarily grouping multiple trains. [0003] Transportation safety is the top priority of rail transit, and emergency response plans for a...

AI Technical Summary

Problems solved by technology

[0004] At present, in rail traction locomotives, there is no emergency escape door that passes through the driver. In urban rail subway vehicles, there is an emergency escape door at the driver's cab end, but it can only be evacuated to the track to escape, and cannot be evacuated directly to the rescue train through the emergency escape door device. On the other hand, achieving the purpose of quick escape does not prevent secondary accidents (such as stampede incidents)
