Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for operating an elevator in an emergency.

If the elevator loses power while it is in operation, the car will stop and passengers will be trapped inside the car. Therefore, an emergency operation is performed in which the car is returned to the rescue floor by switching the power source to an emergency power source such as a private power generation facility. Due to the capacity of the emergency power source, this emergency operation is often performed by giving a return command to each unit one by one. The returning methods at this time include an automatic returning method in which cars are automatically returned in a predetermined order, and a manual returning method in which a staff member operates a returning switch to select a car.

In the case of the automatic return method, the return order is fixed as described above, so there is no problem in confirming it. However, in the case of the manual return method, because the operation is performed by a staff member, it is not possible to know which cars require emergency return, such as cars where a crime has occurred, and the return of such cars may be delayed. Become.

This invention is intended to improve the above-mentioned problems, and aims to provide an emergency operation device for an elevator that can clearly indicate to staff, etc., the return order of cars in an emergency.

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In Figure 1, 1 is the staff management panel installed in the staff room, 2 is the normal power light that lights up when the power is normal and turns off when the power goes out, and 3 is the normal power light that turns off when the power is normal and turns the power into an emergency power source. The emergency power lights 4A to 4C light up when switched, and the return completion lights light up when Units 1 to 3 complete their return (A to C at the end of the code correspond to Units 1 to 3, respectively. The same applies below) ), 5A to 5C are return switches which are also operated manually, and 6A to 6C are return order indicator lights which, when lit, display the number of the car by number.

In Figures 2 and 3, (+) and (-) are DC power supplies, and 7a and 7b are open when power supplies (+) and (-) are supplied from the normal power source, and closed when the normal power source is interrupted. power failure detection relay contact, 8aA~8
aC is a dedicated operation relay contact that closes during dedicated operation when an important passenger is in the car of car No. 1 to No. 3, 8bA to 8bC are dedicated operation relay contacts that are also opened, and 9aA to 9aC are dedicated operation relay contacts that close when a crime occurs in the car. 9bA to 9bC are in-car abnormality notification relay contacts that close when a passenger operates a rescue switch, 9bA to 9bC are in-car abnormality notification relay contacts that also open, and 10 is a return order determining circuit, with input terminals X1, X2, and X3. When a voltage is applied to these terminals, the output terminals F1, S2, and N3 are connected, and the input terminal Y
When a voltage is applied to 1, Y2, Y3, those terminals are connected to the output terminals F1, S2, N3, respectively, and so on, when a voltage is applied to the input terminal of the same character, 1 becomes F1. , 2 is S2, 3 is N
3, respectively. In addition, input terminal X1,
When a voltage is applied to Y2 and Z3, those terminals are connected to the output terminals F1, S2, and N3, respectively, and when a voltage is applied to the input terminals Y1, X2, and Z3, those terminals are connected to the output terminals S1 and N3, respectively. F
2 and N3 are connected, and when a voltage is applied to the input terminals with different letters, X is connected to the same number F, Y is connected to S, and Z is connected to N. . Additionally, if a crime and a special driving condition occur in the same unit, the crime takes priority over the special driving condition. 11A to 11C are No. 1 return command relays that, when energized, issue a command to return the corresponding cars of Cars No. 1 to Car No. 3 to No. 1, respectively; 11aA;
~11aC is its normally open contact, 12A~12C is the second return command relay that also issues a command to return to number 2, and 12aA~12aC are its normally open contacts,
13A to 13C are No. 3 return command relays that also issue a command to return to No. 3, and 13aA to 13aC
is its normally open contact, 14A to 14C are the return order display devices of the first to third machines, respectively, and the input terminal X11
When a voltage is applied between the input terminal Y11 and the output terminal C1, "1" is displayed on the return order indicator 6A of the first machine in FIG. 1, and when a voltage is applied between the input terminal Y11 and the output terminal C1, "1"2" is displayed, and if it is input terminal Z11, "3" is displayed, and if it is input terminal
12, "1" is displayed on the return order indicator 6B of the second car, and so on.

Next, the operation of this embodiment will be explained.

When power (+) and (-) are supplied from the normal power source, the normal power light 2 lights up and the emergency power light 3 lights up.
is off.

When the normal power supply fails, power supplies (+) and (-) are supplied from the emergency power supply, and the power failure detection relays 7a and 7b are closed. And normal power light 2
is turned off, and the emergency power light 3 is turned on (the circuit is omitted). Now, cars No. 1 to No. 3 will stop.

Now, if each car is not in dedicated operation and no crime has occurred, the dedicated operation relay contacts 8bA to 8bC and in-car abnormality notification relay contacts 9bA to 9bC are all closed. Therefore, (+)-7a-8
By the circuit bA-9bA-Z1-F1-11A-(-), the No. 1 return command relay 11A of the No. 1 car is energized, and the contact 11aA is closed. Also, (+)−
7a-8bB-9bB-Z2-S2-12B-(-)
By this circuit, the 2nd return command relay 12 of the 2nd machine
B is energized and contact 12aB is closed. Also,
(+)-7A-8bC-9bC-Z3-N3-13C
The - (-) circuit energizes the No. 3 return command relay 13C of the No. 3 machine, and the contact 13aC is closed. Now, (+)-7b-11aA-X11-C
1-(-) circuit operates the return order display device 14A, and the return order indicator light 6A of the No. 1 car in FIG. 1 displays "1". Similarly, the indicator light 6B of the second machine displays "2" and the third machine displays "3".

Based on this display, the staff first turns the return switch 5A of No. 1 to the "ON" side, a well-known rescue operation is performed, and No. 1 returns to the rescue floor (usually the 1st floor). When the return is completed, the return completion light 4a lights up. Next, by turning the return switch 5B of the No. 2 machine, a rescue operation will be performed in the same manner. The same applies to Unit 3.

Next, assume that a power outage occurs while Unit 1 is in normal operation, Unit 2 is reporting a crime, and Unit 3 is in dedicated operation.

As above, (+)-7a-8bA-9bA-Z
1-N1-13A-(-) circuit energizes No. 3 return command relay 13A of Unit 1, (+)-
7a-9aB-X2-F2-11B-(-) circuit energizes No. 1 return command relay 11B of No. 2 aircraft, (+)-7a-8aC-Y3-S3-12
The No. 2 return command relay 12C of the No. 3 car is energized by the C-(-) circuit. Now, as shown in FIG. 1, the return order indicator lights 6A to 6C display "3" for the first car, "1" for the second car, and "2" for the third car. In other words, the order of priority for return in this case is crime, important customer, and normalcy.

Although it is extremely rare, Unit 1~
When all No. 3 machines are reporting a crime or when they are all in dedicated operation, the priority order of return is the same as when all of them are in normal operation, in the order of No. 1 to No. 3 machines.

It is also possible to implement as follows.

(a) Return order indicator lights 6A to 6C shall be installed at the landing or inside the car.

(a) An audio broadcasting device is used instead of the return order indicator lights 6A to 6C.

(c) In addition to crime and important customer service, priority conditions such as cars with heavy loads, cars located far from the rescue floor, etc., are added to the conditions for determining the order of return.

(d) Automatic return method with auxiliary return switch 5A~
This also applies to those using 5C.

As explained above, in this invention, in the event of an emergency such as a power outage, the car return order is determined by inputting and calculating the car information, and this is displayed in the staff room, etc., so that the staff can identify cars that require emergency return. It is possible to prompt passengers in the car to quickly rescue the passengers by clearly indicating the return operation instructions.
