Abstract

PURPOSE:To provide an elevator indicator device which allows the stop position of a car to be easily confirmed after earthquake control operation CONSTITUTION:If an earthquake sensor starts to operate, a contact Ea is closed and a relay 20 is energized to open a contact 20b. While a landing door and a car door are closed, a relay 40 is energized and a contact 40a is open. Therefore, lights L11 to L33 are all out. When a landing door is opened on the first floor, a contact HD1 is opened to deenergize the relay 40 to close the contact 40b, thereby forming a lighting circuit for the lights L11 to L33.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator indicator device that operates in response to seismic control operation.

[0002]

2. Description of the Related Art When an earthquake occurs in an elevator and the seismic detector operates, the elevator performs seismic control operation, the car is stopped at the nearest floor, the passengers are dropped off, and then the car is put on standby at that floor. When the elevator is on standby, the manager notifies the elevator maintenance company that seismic control operation has been performed. Therefore, the maintenance personnel rushed to the building, first went to the machine room, checked that there were no abnormalities in the control equipment, then got on the car and inspected the hoistway at low speed operation and confirmed that there were no abnormalities. , Return the seismic detector to normal operation, perform normal operation, make sure that the elevator is operating normally, and then return to normal operation. On the other hand, when the seismic intensity of the earthquake is not so large, a method of first inspecting the inside of the hoistway and then inspecting the machine room is also used in the above-mentioned restoration work.

A technique of this kind is described in, for example, Japanese Patent Laid-Open No. 56-113673.

[0004]

By the way, in the above-mentioned prior art, when the maintenance person gets into the car, the indicator is off and the position of the car cannot be known. Therefore, the maintenance staff must open an arbitrary landing door and look into the hoistway to find the floor where the car stops. Therefore, the maintenance staff has to go up and down the stairs, which causes a problem that the physical strength is very exhausted. In addition, there is also a problem that the recovery work time becomes longer accordingly.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide an elevator indicator device capable of easily confirming a stopped position of a car after an earthquake control operation.

[0006]

An object of the present invention is to provide an elevator indicator device for turning off an indicator of a hall when seismic control operation of an elevator is performed. When the hall door is opened after the seismic control operation, the indicator is This is achieved by providing a lighting means for lighting.

[0007]

[Operation] When the seismic control operation is performed, the indicator is turned off. By the way, when the maintenance staff opens an arbitrary landing door to inspect the inside of the hoistway, the indicator lights up by the lighting means. As a result, the position of the car can be easily known, and the maintenance staff can go straight to the floor where the car is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In addition, the elevator shall be in service on the first to third floors.

FIG. 1 is an electrical connection diagram showing an embodiment of an indicator device for an elevator according to the present invention. In the figure, P and N are DC power supply terminals, HD1 to HD
3 is a contact that closes when the hall doors on the 1st to 3rd floors are closed,
CD is a contact that closes when the car door is closed, 40 is a relay that is activated when all landing doors and car doors are closed, 40b is its normally closed contact, and Ea is a normally open that is closed when the seismic detector operates. A contact, 20 is a relay that is activated when the seismic detector operates, and 20a is a normally open contact, 20b.
Is a normally closed contact, RTb is a switch contact for resetting the relay 20, and the contacts 20b and 40b are connected in parallel. F is a finger of the floor selector, S1 to S3 are segments of the floor selector, and the finger F is in contact with the segments S1 to S3 when the car is stopped at the first to third floors. L11 to L33 are electric lights as indicators, and the first digit shows the floor where the electric light is installed and the second digit shows the floor where the car is stopped.

FIG. 2 is a front view of the hall on the first floor. In the figure, HD is a hall door, HB is a hall call button, IN is an indicator provided above the hall door, and L11, L21, and L31 are lit when the car is located on the first floor, the second floor, and the third floor. It is an electric light.

Next, the operation of this embodiment will be described.

When no earthquake occurs, that is, during normal operation, the contact Ea is open, so the relay 20 is deenergized and the contact 20b is always closed. Therefore, when the car travels, the finger F contacts the segments S1 to S3, the lights L11 to L33 are turned on, and the car position is displayed on the indicators on each floor.

Next, an earthquake occurs, the contact Ea is closed, and P
The relay 20 is energized by the -Ea-RTb-20-N circuit and self-held via the contact 20a. Relay 2
It is assumed that the car is stopped at the nearest floor, for example, the second floor by performing the seismic control operation via the control device (not shown) by urging 0. At this time, since the landing door and the car door are closed, the relay 40 is energized and the contact 40b is opened.
Further, since the contact 20b is also open, even if the finger F and the segment S2 are in contact with each other, the lights L21, L22, L2
No. 3 is unlit The stop position of the car is unknown. When the maintenance staff opens the landing door on the first floor on the first floor, the contact HD1 opens, so the relay 40 is deenergized. Therefore, contact 4
0b is closed, so PF-S2-L23, L22, L
21-N circuit is formed and lights L23, L22, L2
1 lights up, that is, the light L21 at the first floor hall
Indicates that the car is stopped on the second floor. Therefore, the maintenance staff can close the hall door on the first floor and go straight to the second floor to get into the car. The same applies when the doors on the second floor or the third floor are opened, and a description thereof will be omitted.

As described above, the indicator lights up regardless of which hall door is opened during the seismic control operation, so that the car position can be easily known.

[0015]

As described above, according to the present invention, since the indicator light is turned on when an arbitrary landing door is opened, the maintenance personnel go straight to the site and open the landing door, Since the indicator light is turned on, it is possible to easily know the position where the car is stopped and improve the efficiency of the returning work.
