Abstract

The invention discloses an escalator accident emergency stop monitoring safety device. The escalator accident emergency stop monitoring safety device mainly comprises steps, a control system, a driving motor, a driving tensioning device, step pedals, an escalator frame, touch holding belts and an escalator way guiding rail. The escalator accident emergency stop monitoring safety device is characterized in that pedal anti-falling devices are arranged below the step pedal at the escalator inlet end and the step pedal at the escalator outlet end; each pedal anti-falling device comprises a fixing seat, supporting springs and microswitches, the fixing seat is fixed below the step pedal, the four microswitches connected in series are arranged on the fixing seat, and the fixing seat and the step pedal are fixedly connected through the supporting springs; each microswitch is located between two fixing screws of the corresponding step pedal, and the upper end of the microswitch corresponds to the center of the step pedal; each microswitch is connected with the control system. The escalator accident emergency stop monitoring safety device has the advantages that the structure is novel, operation is easy, safety and reliability are achieved, energy is saved, the service life of the motor is prolonged, and casualty accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of traffic elevators, in particular to an emergency stop monitoring safety device for escalators. Background technique [0002] As we all know, escalators at home and abroad are used in many places such as railway stations, docks, airports, supermarkets, etc., which are convenient for people to go up and down. The number of escalators has doubled year by year, and the accidents of people taking escalators have increased year by year. People call them "elevators that eat people." Witnessed various escalator mass casualty accident scene videos, objective scientific analysis and on-site investigation for many years. Once on the outdoor escalator at the exit of Jinan Railway Station, I saw a middle-aged woman carrying a large bag on the escalator. It was raining that day, and the two sides of the outdoor escalator touched the top of the handrail. On the escalator, the person lost his center of gravity and fell...
