Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an operating device for an elevator with earthquake control operation having an express zone.

[Prior art]

In an elevator that has an express zone, and if the car is running in the express zone during an earthquake, it will stop suddenly and after a predetermined period of time, the car will automatically operate at low speed in the direction away from the weight. Conventionally, when the weights stopped at the same position, the control device always determined one direction and made them move.

If the weight is off the rail, there is a danger that the basket and weight will collide and start moving.

[Summary of the invention]

This invention was made to solve the above-mentioned conventional drawbacks, and it prevents the car from automatically traveling even after a predetermined period of time when the car stops at the same position as the main car in the express zone during an earthquake. Therefore, we propose an elevator operating system that can ensure the safety of passengers.

Next, the operation of the elevator operating system of the present invention configured as described above will be explained.

If a 100 gal earthquake occurs while the car is running near the 10th floor, the 10 (1 gal switch 15
is closed, and the earthquake detection relay 1T is energized. This closes the normally open contact 17a.

At this time, the car is running near the 10th floor, so (1
1) Normally open contact 10Fb of the car position relay on the 10th floor is closed.

Therefore, by closing the normally open contact 17a,
In FIG. 2, power line L1-normally open contact 10Fb-
A closed circuit of normally open contact 17a--earthquake nearest floor stop relay 22 and nearest floor stop light--power line L2 is formed.

As a result, the nearest floor stop relay 22 and the nearest floor stop light 2
3 is energized at the same time, the car stops at the nearest floor, and the nearest floor stop light lights up to indicate that the car has stopped at the nearest floor, that is, the 10th floor. .

In addition, as shown in Figure 1 (,), if a 100 gal earthquake occurs while the car is running on the 7th floor, the same as above will occur.
100 gal switch 15 is closed and earthquake detection relay 1
7 is energized and its normally open contact 17b is closed.

When the normally open contact 17b is closed, the normally open contact 7Fb of the car position relay 1T on the 7th floor is already closed.
A closed circuit of power line L1 - normally open contact 7Fb - normally (12) open contact 17b - express zone relay 24 and express zone light 25 - power line L2 is formed.

As a result, the express zone relay 24 is energized and at the same time the express zone light 25 is turned on. By lighting up the express zone light 25, it is indicated that the car is to be stopped suddenly,
Furthermore, when the express zone relay 24 is energized, its normally closed contact 24b (FIG. 4) is opened, and the safety relay 29 is deenergized. Therefore, the car is brought to a sudden stop.

1 minute after the earthquake occurs, the earthquake time relay 30
30m of contacts are closed. At this time, since the earthquake detection relay 17 is energized and its normally open contact 17a is also closed, the normally open contact 301L of the earthquake time relay 30 is closed, thereby connecting the power line L1 to the earthquake rescue. Normally closed contact 32d of relay 32 - Normally open contact 30m of earthquake time relay 30 - Normally closed contact 20a of 150 gal detection relay 20 (not yet energized) - Normally closed contact 13c of intermediate detection relay 13 - Earthquake detection Normally open contact 17e of relay 17
- Door zone relay contact 35 - Earthquake low speed travel relay 3
6- A closed circuit of power line L2 is formed.

In this way, this earthquake low-speed running relay 36 is energized,
Its normally closed contact 36b is opened. This normally closed contact 36b
By opening, the high-speed relay 38 is deenergized and the car is brought to a low speed.

In addition, the normally open contacts 36& are closed by the energization of the earthquake low speed relay 36. With this, the power line L1-
A closed circuit of normally open contact 36 &-- governor switch 26--top floor over-travel prevention switch 27--lowest floor over-travel prevention switch 2B--safety relay 29--power line L2 is formed.

As a result, safety relay 29 is energized. Additionally, the upper layer detection relay 12 has already been energized, and its normally open contact 1
2b is closed, and the normally open contact 17g of the earthquake detection relay 17 is also closed.

Therefore, a closed circuit of power line L1 - normally open contact 13d - normally open contact 17g - normally open contact 12b - normally closed contact 44a - upward relay 43 - power line T, 2 is formed, and this upward relay 43 Forced.

When the safety relay 29 and the upward relay 43 are energized, the car rises at a lower speed than K.

When the car ascends at low speed and enters the 9th floor door zone, the door zone relay contact 35 opens. For this reason, the earthquake low-speed traveling relay 36 is deenergized, and its normally open contact 36a
is opened and safety IJt/-29 is deenergized. Therefore, the car stops +1 (9th floor).

The case of FIG. 1(b) is similar to the above, and the car runs at low speed toward the first floor.

If h is above and the strength of the earthquake is 150 gal or more,
The 150 gal switch 19 is closed, the 150 gal detection relay 20 is energized, and its normally open contact 2°a is opened.

Therefore, the low-speed travel relay 36 is not energized during an earthquake.
The basket does not run.

However, when the earthquake rescue switch 31 is turned on at the discretion of the staff, the power line L1 - earthquake rescue (15) switch 31 - normally open contact 17d of the earthquake detection relay 17 (
(closed at the same time as the earthquake occurs) -Earthquake rescue relay 32-
A closed circuit of power line L2 is formed.

As a result, the earthquake rescue relay 32 is energized, so the door opening button relay 34 is energized only while the passenger in the car is pushing the door opening button 33.

When the door open button 34 is energized, its normally open contact 34m is closed, and the power line L1 - earthquake rescue relay 3 is closed.
2 normally open contact 32a - normally open contact 34 of door open button relay 34
a - Connection point P1 - Normally open contact 17e of earthquake detection relay 17
- Door zone relay contact 35 - Earthquake low speed travel relay 3
6- A closed circuit of power line L2 is formed.

Accordingly, the earthquake low speed travel relay 36 is energized and the vehicle can travel at low speed.

Next, the case shown in FIG. 1(,) will be described. in this case,
Intermediate detection relay 13 (Fig. 2) is energized and 100
When a Gal earthquake occurs, the normally closed contact 13c (FIG. 4) of the intermediate detection relay 13 is opened.

(16) For this reason, the low speed running relay 36 is not activated during an earthquake, and the car cannot run.

In addition, if the earthquake detection relay 17 is connected, its normally open contact 17f is closed, and the normally open contact 136 of the intermediate detection relay 13 is closed). The normally closed contact 36c of the relay 36 is also closed.

Therefore, at the same time that the intermediate indicator light 39 lights up, the intermediate warning buzzer 40 sounds to notify that the car 1 and the weight 2 are in the intermediate position and that an earthquake has occurred.

At this time, at the discretion of the staff, the earthquake rescue switch 31
When the button is turned on, the earthquake rescue relay 32 is energized, so if a passenger in the car presses the door opening button 33 and the up direction button 41 or down direction button 42 at the same time, the button corresponding to the pressed direction will be activated. Then, the upper relay 43 or the lower relay 44 is energized.

Further, since the intermediate detection relay 13 is energized and the earthquake detection relay 17 is also energized, the very low speed relay 45 is energized. Therefore, the car runs at a very low speed in the direction in which the upward relay 43 or the downward relay 44 is energized, and the passengers inside the car can be rescued.

On the other hand, if the passenger notices something abnormal while the car is running at this extremely low speed and releases his/her hand from the up direction button 41''!! and down direction button 42, the upward relay 43 or the downward relay 44 will not be energized. , the car stops immediately.

Then, the passenger presses a button in the opposite direction (up direction button 41 or down direction button 42), so that the car runs at a very low speed in the opposite direction.

When the car position leaves the 6th floor, the intermediate detection relay 13 is deenergized, so as in the case of FIG. 1(,) or FIG. Even if you release your hand from the button 42, the vehicle will automatically continue running at the normal low speed.

Note that this example is an 11-story building, with the 2nd to 8th floors serving as express zones, but it is also possible to implement other systems other than the above.

Also, the strength of the earthquake was set at 100 gal and 150 gal,
Other combinations are also possible.

Furthermore, although the case where low-speed automatic driving is performed one minute after the occurrence of an earthquake has been illustrated, it is possible in other cases as well.
When traveling from an intermediate position, the normal low speed is also slower, but it is also possible to set the normal low speed.

In addition, although we have shown the case where the ascending direction button 41 and descending direction button 42 are provided in the car, it is preferable to use the destination button (for example, the 9th floor button for ascending and the 1st floor button for descending). It's okay.

〔Effect of the invention〕

As described above, according to the elevator operation device of the present invention, in an elevator having an express zone, when a car stops at a position where the weight passes the car in the express zone during an earthquake, the car is automatically prevented from running. This can improve passenger safety.
