Escalator non-contact type instant help switch

Abstract

The invention relates to an escalator non-contact type instant help switch, comprising an escalator, a pedal and a floor plate, wherein the pedal is connected with the floor plate, an escalator circuit used for driving the escalator to work is arranged on the escalator; the escalator circuit is provided with an electric motor, an escalator switch, two switches I, two switches II, two switches III and two switches IV; the switches I, the escalator switch and the electric motor are connected in series; the switches II, the switches II and the switches IV are connected in parallel and then connected to the escalator circuit in series; the two groups of switches I, switches II, switches III and switches IV are connected to the escalator circuit in a symmetric way; a voice control system is arranged on each of the two switches I; and an optical control system is arranged on each of the two groups of switches II, switches III and switches IV. According to the invention, the voice control system is used for receiving yelp of a victim in danger or the optical control system is used for receiving a signal after the victim falls down, so as to trigger the switches and brake the escalator instantly, thus ensuring the safety of persons taking the escalator.

Description

technical field [0001] The invention relates to the technical field of elevator production, in particular to a non-touch instantaneous life-saving switch of an escalator. Background technique [0002] At present, the escalators that have been used for a long time often have loose connections or break away from the elevator due to the unreliable connection of the cover plate. Elevator accidents often occur, causing people to fall or get involved in the elevator, causing injuries or even death, and posing a threat to public safety. According to the survey, the current common escalator is equipped with a manual trigger device at the upper and lower ends of the elevator 30 cm below the pedal in contact with the floor. Once the pedal is opened or someone falls in, the elevator will stop running quickly, but These manual emergency brake switches are about 50 centimeters away from the welcome pedal. When an accident occurs, it is impossible for the victim to find and press the brak...

[0002] At present, the escalators that have been used for a long time often have loose connections or break away from the elevator due to the unreliable connection of the cover plate. Elevator accidents often occur, causing people to fall or get involved in the elevator, causing injuries or even death, and posing a threat to public safety. According to the survey, the current common escalator is equipped with a manual trigger device at the upper and lower ends of the elevator 30 cm below the pedal in contact with the floor. Once the pedal is opened or someone falls in, the elevator will stop running quickly, but These manual emergency brake switches are about 50 centimeters away from the welcome pedal. When an accident occurs, it is impossible for the victim to find and press the brake switch in an instant, especially when the victim has been injured. , even more impossible; therefore, these switches are passive to the victim, and the mechanism cannot be triggered immediately when the person is in danger, wasting precious response time
