Problems solved by technology

[0006] The problem with the above method is that it has certain limitations: when the sound or photoelectric warning signal is issued, the landing doors have been opened or the trend of opening is irresistible; or the time for the warning signal to sound is relatively short
And under such circumstances, if the operator wants to fall, the tendency of his fall is unavoidable.

Embodiment Construction

[0059] like figure 1 As shown, the elevator floor door unlocking and warning device of the present invention includes a micro switch 1, the micro switch 1 is connected in series with the warning unit and the resistance element 19 for preventing overcurrent, and the warning unit includes a buzzer 17 and a warning light 18 connected in parallel The opening and closing of the micro switch 1 is controlled by the landing door lock cylinder device 25;

[0060] When the landing door lock cylinder device 25 closes the micro switch 1, the circuit is connected, the warning unit is triggered, the buzzer 17 makes a sound, and the warning light 18 sends out a photoelectric signal;

[0061] When the landing door lock cylinder device 25 disconnects the microswitch 1, the circuit is disconnected immediately or with a delay, and the alarm unit is triggered to end the action immediately or with a delay; when the alarm unit is triggered to end the action, the buzzer 17 stops sounding, warning L...

Abstract

The invention discloses an insertion trigger type door lock cylinder device for a landing door. The device comprises a lock cylinder shaft, the front portion of the lock cylinder shaft is sleeved with a floating mandrel serving as a trigger element, the front end of the floating mandrel can overcome the elastic force of a spring to move to the inside of a lock after being stressed, and a poking plate of a microswitch is loosened. Before an elevator landing is manually opened outside through a triangular key, a warning device capable of sending sounds and / or photoelectric signals can be immediately triggered while the triangular key is inserted, and an operator is warned of impending safety hidden hazards; the warned operator rotates the key to open a door lock, the door lock of the landing door is unlocked, and the landing door is opened. Compared with an existing device for sending out alarms when the landing door is opened, the lock cylinder device is more efficient, more timely and safer. The invention further discloses an elevator landing door unlocking and warning device provided with the insertion trigger type door lock cylinder device for the landing door.

Description

technical field [0001] The invention relates to a control device for an elevator door lock, in particular to an insertion trigger type landing door lock cylinder device. The invention also relates to an elevator landing door unlocking and warning device. Background technique [0002] When the elevator landing door is opened on a non-elevator car parking floor, there will be a safety accident caused by personnel unintentionally falling from the landing into the elevator shaft. Article 7.7.1 of "GB 7588-2003 Safety Code for Elevator Manufacturing and Installation" stipulates that during normal operation, the landing door (or any one of the multiple landing doors) should not be opened unless the car is at the landing door. Stopping or stopping in the unlocking area; Article 7.7.3.2 stipulates that each landing door can be opened from the outside by means of a key matching the unlocking triangular key hole specified in Appendix B...After an emergency unlocking, the door lock T...
