Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elevator door closure confirmation device when manually rescuing an elevator.

[Technical background of the invention and its problems]

When an elevator stops between floors due to malfunction, power outage, etc., passengers trapped inside the car must be rescued outside. When rescuing passengers, cut off the power to the elevator, manually loosen the brake on the hoisting machine, gradually move the car until it stops at the hall door, and rescue the passengers inside the car.

Generally, trained elevator maintenance personnel perform this rescue work, but it takes time for the elevator maintenance personnel to arrive at the scene, and the passengers in the car may become impatient. In other words, if you live in a mountainous area or remote island far away from the elevator service base, or if you live in a rural area where it takes a long time for maintenance personnel to arrive, such as late at night, the building manager or fire department personnel will rescues the victim by manually moving the elevator car.

Further, the elevator car door can be easily opened when the power is cut off, and the car door can be opened even when the power is on. Generally, the elevator machine room and the inside of the car communicate with each other via intercom to check the condition inside the car and perform rescue work.

However, if the elevator car is moved with the car door open during rescue work, a problem arises in that a person may become caught between the car and the wall.

[Object of the Invention] An object of the present invention is to provide an elevator door closing confirmation device that confirms that the door is closed and safely rescues the elevator when manually rescuing the elevator.

[Summary of the invention]

In the case of manual rescue, the interlock switch that confirms the closed state of the elevator car door and hall door is connected to the battery via the changeover switch to confirm that the door is closed.

[Embodiments of the invention]

The present invention will be explained based on embodiments shown in the drawings.

Hold door interlock switches ILS and 2LS are provided on each floor between the control power supplies P and N shown on the screen via the A side of changeover switches IS and 2S.

..., nLs series circuit and a car door interlock switch GLS provided on the car side are connected. Further, a door closing confirmation relay DCR is connected between the A side of the changeover switch 2S and the control power supply N.

On the B side of the changeover switches IS and 2S, there is provided a series circuit of a switch BA connected in parallel to the interlock switch and a door close confirmation lamp LNP provided in the elevator machine room. A buzzer BZ for confirming door closure and an indicator light CL for indicating that the car is being rescued are connected in parallel to the confirmation lamp LAP.

Next, the operation will be explained.

For normal operation of the elevator, the changeover switches IS and 28 are connected to the A side. When performing manual rescue work, connect the changeover switches IS and 2S to the B side, use the 8 batteries as a power source, and pass the hold door interlock switches ILS, 2L8°..., nT, 8 to turn on the car door interlock. Check that the switch GLS door is closed. If the battery BA is connected in this way, the door close confirmation lamp T and AP will light up in a place visible from near the hoisting machine in the elevator machine room (not shown), and the buzzer BZ will sound, thereby safely rescuing the person inside the car. becomes possible.

Furthermore, a rescue indicator light CL lights up inside the car to alleviate the anxiety of the passengers. In addition, if an auto-announcement is set up in conjunction with this, a rescue operation will be performed for passengers in the car. Please wait for a while.The first prize will also be broadcast. In this way, the elevator car is gradually moved while confirming that the door is closed, and when it matches the floor level, the car is stopped, the door is opened, and the passengers inside the car are rescued.

〔Effect of the invention〕

According to the present invention, during manual elevator rescue work, a lamp is displayed or a buzzer sounds to confirm that the bottom door and hall door are closed, making it possible to safely rescue passengers in the car.
