It is miscellaneous, easily people is involved in wherein when falling, causes great life danger.Being collapsed in generation pedal for escalator causes people to fall
During emergency safety accident, manually there is larger limitation in the way of emergency stop button brakes staircase, in urgent thing
Therefore occur to manually booting in brake apparatus this period, accident causes victim expendable somatic damage, this
Outside, when emergency episode occurs, personnel's fear can cause braking staircase not in time, cause to miss optimal rescue time.
Utility model content
The purpose of this utility model be exactly to solve the above-mentioned problems and provide it is a kind of it is safe to use, with automatic protection work(
The staircase Active foot plate protective device of energy.
The purpose of this utility model is achieved through the following technical solutions：
A kind of staircase Active foot plate protective device, including Active foot plate, the Active foot plate are installed on elevator outline border,
Further include installed in the early warning mechanism for being used to monitor Active foot plate position between Active foot plate and elevator outline border, and arranged on activity
Pedal lower part is used for the control mechanism of emergency braking elevator, and the early warning mechanism includes position detecting switch, the Active foot plate
Top or side set alarm unit, and the position detecting switch is connected with alarm unit by circuit, when Active foot plate is normal
During installed in elevator outline border, alarm switch pushes, and alarm unit is closed；Loosened when between Active foot plate and elevator outline border,
Bullet on alarm switch, alarm unit are opened and send alarm；The control mechanism is included installed in the red of Active foot plate bottom
Outer opposite type sensor, the infrared emission sensor include infrared transmitter and infrared remote receiver, infrared remote receiver connection control
Device, the control circuit of the controller access staircase, emergency braking is carried out to elevator.
Further, the position detecting switch is round button, in the card slot of Active foot plate and elevator outline border,
The lower part of the position detecting switch sets elastic component, and elastic component is in confined state during normal condition.
Further, the alarm unit is alarm, including warning lamp and voice prompting device.
Further, the infrared emission sensor is tight by conducting wire and loudspeaker, emergency power off device, motor driving shaft
Anxious brake apparatus series connection, can pass through infrared emission sensor coordinated signals.
Further, the infrared radiation direction of the infrared emission sensor is horizontal direction, when Active foot plate is sent out
When life collapses, infrared ray is disconnected according to barrier, carries out coordinated signals.
Further, the back of the Active foot plate is equipped with alert flag, can serve as warning sign in elevator reparing,
It is easy to use without preparing warning sign again.
The present apparatus monitors the early warning mechanism of Active foot plate position by being set between Active foot plate and elevator frame, to work
Dynamic pedal is monitored in real time, when Active foot plate occurs change in location, loosens when abnormal phenomenon, can be sent alarm, be reminded
User note that and remind maintenance personnel to be safeguarded in time, to eliminate safe hidden trouble, so form first of security protection.
In addition, control mechanism is set in Active foot plate lower part, using detection sensor of the infrared emission sensor as security incident, profit
The characteristics of with the good in anti-interference performance of infrared emission sensor, high sensitivity, realize and overturn in escalator treadboards contingency
Or emergency braking when collapsing accident and protective alarming, being capable of emergency braking to reach when pedal for escalator security incident occurs
Elevator is simultaneously alarmed, and avoids people that people is involved in driving device after falling, and causes more major injury, and it is anti-to be thusly-formed second installation
Shield.
