Door lock mechanism for automatic driving metro vehicle urgent evacuation equipment

Abstract

The invention provides a door lock mechanism for automatic driving metro vehicle urgent evacuation equipment. The door lock mechanism comprises a lock mechanism installing frame, an electromagnet, anarmature, a swing rod unlocking device and an urgent unlocking device. The swing rod unlocking device is installed on the middle portion of the bottom face of the lock mechanism installing frame. Lockblock assemblies are fixed to the two ends of the bottom face of the lock mechanism installing frame correspondingly. The swing rod unlocking device and the two lock block assemblies are connected through first steel cables. An armature support capable of moving transversely is movably connected to the lock mechanism installing frame. The armature support and the urgent unlocking device are connected through second steel cables. When a train operates normally, the electromagnet is energized, the armature is located at a high position, after a train control system cuts off power of the electromagnet, the armature falls, the armature moves horizontally along with the armature support to poke a swing rod of the swing rod unlocking device to swing, the first steel cables on the two sides arelocally rolled into the swing rod unlocking device, the first steel cables drive lock hooks in the lock block assemblies to act, and therefore the lock hooks are separated from lock buckles on door hinges. The door lock mechanism can meet the requirement of operation of automatic driving metro trains, and a passenger can carry out door opening operation on the permissive condition of the train control system.

Description

Technical field [0001] The invention relates to a door lock mechanism of an emergency evacuation device for an automatic driving subway vehicle. Background technique [0002] Emergency evacuation doors must be installed on the front of subway vehicles, which can be deployed in an emergency. The ramp-type emergency evacuation doors can be deployed to form an evacuation ramp. The Chinese invention patent application with publication number CN103241251A discloses a ramp-type emergency evacuation door for subway locomotives, which has a door frame and an outward-turning door leaf. Currently, subway vehicles have a driver, and the unlock switch is in the front of the car. When an emergency occurs, the driver will unlock the emergency evacuation door. The self-driving subway vehicle realizes fully automatic control during the entire operation process. There is no driver in the train and passengers may enter the front of the train. Once someone accidentally touches the unlock switch, i...

Problems solved by technology

However, self-driving subway vehicles realize fully automatic control throughout the entire operation process. There is no driver on the train, and passengers may enter the front of the train. Once someone accidentally touches the unlock switch, it will bring harm to the normal operation of the train and pose a safety hazard.
