Tourism cable car emergency door stairs double-control apparatus with velocity modulation and interlock functions

Abstract

The invention relates to a double-control device of an emergency door ladder of a sightseeing cable car. The double-control device is provided with a start switch, a close switch and a speed regulation option switch of an automatic door and a rope ladder, a control circuit for the power source polarity and rotating speed of an automatic door DC machine, a control circuit for the rotating direction and rotating speed of a rope ladder type DC brushless machine, a liquid crystal display screen, and is controlled by a singlechip. The double-control device has the advantages that when tourists are trapped in a sightseeing cable car in the event of mechanical failure, power failure or natural disasters such as earthquake, the liquid crystal display screen displays information supplied for selection of the start switch, the close switch and the speed regulation option switch of the emergency automatic door and the self-help rope ladder, and a corresponding switch is pressed for acknowledgement; speed-regulation functions of the automatic door and the rope ladder ensure that the self-help rope ladder of the sightseeing cable car can be opened at a set speed; a set of touch switches of each of the automatic door and the rope ladder have interlocking function between a starting key and a closing key, so that the self-help rope ladder is opened before the emergency automatic door is opened and is closed after the emergency automatic door is closed, thereby ensuring the safety of the trapped tourists during evacuation.
