Description

  The present invention relates to a rescue operation apparatus for an elevator that rescues a passenger of a faulty elevator that has failed and stopped from an adjacent rescue elevator.

In general, when any one of the elevators of a plurality of elevators breaks down and stops, the rescue elevator car travels to the stop position of the failed elevator car, and the rescue door provided on the side of each car Open the door. Next, an evacuation ladder is laid between the rescue car and the malfunction car, and passengers in the malfunction car are evacuated to the rescue car. However, depending on the stop position of the broken elevator car, a building beam such as a building beam may be located between the rescue elevator car and the broken elevator car. May become uncertain. In such a case, it is unavoidable to give up the rescue with an evacuation ladder and change to another rescue method. Therefore, the rescue time becomes longer and the passengers are worried.
In the conventional device, in order to prevent the rescue time from being prolonged due to obstacle interference, a reflector is attached to the main rail that does not face the obstacle, and the obstacle that detects that there is no obstacle when facing the reflector An object detector is provided on the car, and the presence / absence of an obstacle is displayed on a display means provided in the car (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 5-40267

  In the conventional elevator rescue operation apparatus as described above, an obstacle detector and a reflecting mirror only for detecting the presence or absence of an obstacle must be added to the car and the main rail. It looks bad in the elevator where the appearance is exposed. In addition, since an optical detection device is used, for example, a cable that does not obstruct the rescue, such as a cable, if it is positioned between the obstacle detector and the reflecting mirror, it will be erroneously detected as an obstacle obstructing the rescue. There is a possibility that.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an elevator rescue operation device that can prevent the appearance from being deteriorated and reduce the possibility of malfunction.

  The elevator rescue operation apparatus according to the present invention includes a car position detection unit that detects a car position of each elevator, and controls the operation of each elevator based on the car position detected by the car position detection unit. When the elevator of the elevator breaks down, an obstacle is located between the operation control means for driving the rescue elevator car to the stop position of the failed elevator car and the rescue elevator car and the fault elevator car, Storage means for storing the non-rescueable area in the hoistway where the vehicle is blocked, and when any one of the elevators breaks down, the rescue elevator car position detected by the car position detection means and the rescue means stored in the storage means Judgment means for determining whether or not the stop position of the car of the malfunction elevator is within the rescue impossible area based on the impossible area Equipped with a.

  According to the elevator rescue operation apparatus of the present invention, the judging means stops the car of the faulty elevator based on the car position of the faulty elevator detected by the car position detecting means and the non-rescueable area stored in the memory means. Since it is determined whether or not the position is in the non-rescuable area, it can be determined whether or not the car is located in the non-rescuable area by using the car position detection means used for the operation control of the car, The need to add a detection device only for detecting the presence or absence of an obstacle can be eliminated, and deterioration of the appearance can be prevented. In addition, since optical detection equipment is not used to detect whether there is interference from obstacles, it is possible to reduce the possibility of false detection of obstacles such as cables that do not interfere with rescue, and malfunctions. The possibility of this can be reduced.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a configuration diagram illustrating an elevator rescue operation apparatus according to Embodiment 1 of the present invention. In the figure, first and second elevators (No. 1 and No. 2) are provided side by side in a building. First, the overall configuration of the first and second elevators will be described. A machine room 2 is provided in the upper part of the hoistway 1. The machine room 2 includes first and second hoisting machines 10 and 20, first and second control panels 11 and 21, first and second speed governors 12 and 22, and machine room display. Part 4 is arranged. First and second main ropes 13 and 23 are wound around the hoisting machines 10 and 20. In the hoistway 1, first and second cars 14 and 24 and first and second counterweights 15 and 25 are suspended by main ropes 13 and 23. The operations of the hoisting machines 10 and 20 are controlled by the control panels 11 and 21. That is, the control panels 11 and 21 control the operation of the cars 14 and 24. The control panels 11 and 21 are computers having an information storage unit (RAM and ROM) that stores information such as programs and a processing unit (CPU) that performs arithmetic processing based on information in the information storage unit. It is.

  In the lower part (pit part) of the hoistway 1, first and second tension wheels 16 and 26 are arranged. First and second governor ropes 17 and 27 are wound around the speed governors 12 and 22 and the tension wheels 16 and 26. The cars 14 and 24 are connected to the governor ropes 17 and 27. That is, the governor ropes 17 and 27 are circulated in conjunction with the traveling of the cars 14 and 24. The governors 12 and 22 rotate in conjunction with the traveling of the cars 14 and 24. The speed governors 12 and 22 are attached with first and second encoders 12 a and 22 a that output signals corresponding to the rotational operation of the speed governors 12 and 22, that is, traveling of the cars 14 and 24. As the encoders 12a and 22a, for example, an incremental rotary encoder or the like that outputs a signal corresponding to the moving amount and moving direction of the cars 14 and 24 is used. The control panels 11 and 21 calculate the positions (cage positions) of the cars 14 and 24 in the hoistway 1 based on the outputs of the encoders 12a and 22a.

  Here, as shown in FIG. 1, the first and second elevators (No. 1 and No. 2) are provided with a stop floor and a non-stop floor (passage floor). In FIG. 1, “◯” indicates a stop floor and “×” indicates a non-stop floor. That is, the lower zone from the first floor to the fourth floor and the upper zone from the 13th floor to the 15th floor are the stop floors, and the middle zone from the fifth floor to the 12th floor is a non-stop floor (hereinafter, express zone) It is called).

  For example, a monitoring panel 5 is arranged in a monitoring room such as a disaster prevention center in a building. The monitoring panel 5 monitors whether or not a failure has occurred in the first and second elevators. Here, it is assumed that the first elevator breaks down on the 8th floor in the express zone and the emergency stop occurs. As a method of rescuing the passenger of the first elevator who has stopped urgently, there is a method of releasing the brake of the first hoisting machine 10 and causing the first car 14 to travel to the nearest landing floor. As another method, there is a method in which a driving operation terminal is connected to the first control panel 11 and manual operation is performed by operating the terminal. Further, as another method, the second car 24 of the second elevator (rescue elevator) adjacent to the first elevator (failed elevator) is caused to travel to the stop position of the first car 14, and the cars 14, There is a method in which the rescue door 3 provided at 24 is opened, and an evacuation ladder is laid between the cars 14 and 24 to evacuate passengers in the first car 14 to the second car 24. As described above, when the stop position of the car 14 is in the middle of the express zone and is at a distance to the stop floor, the second car 24 is driven to the stop position of the first car 14. A rescue method for evacuating passengers in the first car 14 to the second car 24 is employed. This is because when the first car 14 is caused to travel by releasing the brake of the first hoisting machine 10 and when the first car 14 is caused to travel manually, the first car 14 is moved at a low speed. This is because it is only possible to travel and it takes time to travel the first car 14 to the nearest stop floor. However, depending on the stop position of the first car 14, the building beam 6 (obstacle) may be positioned between the second car 24 and the building beam 6 may prevent the rescue.

  Hereinafter, the structure of the rescue operation apparatus of an elevator is demonstrated in detail. FIG. 2 is a block diagram showing the rescue operation apparatus for the elevator shown in FIG. In the figure, the monitoring panel 5 includes an abnormal buzzer 5a, first and second emergency recall switches 5b and 5c, and first and second monitoring panel indicators 5d and 5e (monitoring room indicators). Yes. The monitoring panel 5 is based on an abnormal buzzer 5a indicating the determination results of the determination units 11d and 21d of the control panels 11 and 12d based on the outputs of sensors provided in the hoistway 1 and the machine room 2, and various types of failure information. The first and second elevators are monitored for failure. The first and second emergency recall switches 5b and 5c and the first and second monitoring panel indicators 5d and 5e correspond to the first and second elevators, respectively. Here, as described above, when the first elevator fails, the first control panel 11 outputs a failure detection signal to the monitoring panel 5. In response to this, the abnormal buzzer 5a is sounded to notify the failure of the first elevator. The ringing of the abnormal buzzer 5a is stopped by maintenance personnel.

  The first and second control panels 11 and 21 include first and second position calculation units 11a and 21a, first and second operation control units 11b and 21b, and first and second storage units 11c. , 21c and first and second determination units 11d, 21d. The position calculation units 11a and 21a obtain the positions of the cars 14 and 15 based on the outputs of the encoders 12a and 22a, respectively. Specifically, the position calculation units 11a and 21a count the pulses output from the encoders 12a and 22a, and obtain the positions of the cars 14 and 15 by multiplying the number of pulses by a predetermined coefficient. The operation control units 11b and 21b control the operation of the cars 14 and 15 based on the car position obtained by the position calculation units 11a and 21a. The operation modes of the operation controllers 11b and 21b include a normal operation mode, a recall operation mode, a rescue operation mode (docking operation mode), an independent operation mode, and a manual operation mode (registered operation mode). Yes. Here, the priority order is set in the various operation modes from the content of the operation, and is usually in the order of manual operation, rescue operation, recall operation, independent operation, and normal operation from the higher priority.

  When the second determination unit 21d detects a failure detection signal from the first control panel 11 indicating a failure of the first elevator, the second determination unit 21d inputs a stop position request signal to the first position calculation unit 11a. When detecting the stop position request signal, the first position calculation unit 11 a inputs stop position information indicating the stop position of the first car 14 to the second control panel 21. The first and second storage units 11c and 21c are located in the hoistway 1 where the building beam 6 is located between the first car 14 and the second car 24, and rescue is prevented by the building beam 6. The unusable area is stored. The non-rescueable area will be described in detail later. When the second determination unit 21d detects the stop position information, the second determination unit 21d stores the stop position information (the stop position of the first car obtained by the first position calculation unit 11a) and the second storage unit 21c. It is determined whether the stop position of the first car 14 is within the non-rescueable area based on the non-rescuable area. Specifically, the second determination unit 21d takes an AND between the stop position information and the non-rescueable area of the second storage unit 21c, and cannot be rescued when the data of the calculation result is on (FF). It is determined that the area is within the area, and if it is off (00), it is determined that the area is outside the unrescable area. Note that the ON / OFF conditions of this data may be reversed. That is, the area that cannot be rescued may be reversed and used as information on an area where the rescue by the building beam 6 is not hindered.

  The second determination unit 21d displays the determination result on the first monitoring panel display 5d. Specifically, when it is determined that the stop position of the first car 14 is outside the area where rescue is not possible, the rescue lamp of the first monitoring panel display 5d is turned on. When the manager stops the abnormal buzzer 5a, he confirms that the rescueable lamp of the first monitoring panel display 5d is turned on and off, and if it is on, turns on the second emergency recall switch 5b, Contact maintenance personnel to move to lobby level. When the second emergency recall switch 5b is turned on, it inputs a recall command to the operation control unit 21b. When the operation control unit 21b detects a recall command, the second elevator performs operation control in the recall operation mode. When operating in the recall operation mode, in the case of two multi-cars, there is no other elevator that can respond, so the registered hall call and car call are canceled and the new hall call and car call are invalidated. When the first elevator is out of order, the first operation control unit 21b holds the first car 14 stationary. In addition, when the first elevator is out of order, the second operation control unit 21b causes the second car 24 to travel to the lobby floor and announces, for example, “Get out of the elevator when the door opens”. The contents are broadcast to an in-car alarm (not shown) to notify the passenger that the rescue operation is started. In addition, the second operation control unit 21b places the second car 24 on the lobby floor, and then causes the second car 24 to stand open. When the rescue buzzer of the first monitoring panel display 5d is turned off when the abnormal buzzer 5a is stopped, for example, measures such as contacting maintenance personnel to move to the machine room 2 are taken. .

  In the second car 24, an operation mode switching operation part 24a, an in-car display 24b, and a registration operation part 24c are arranged. Although not shown, the first car 14 is provided with an operation mode switching operation unit, an in-car display, and a registration operation unit. The operation mode switching operation unit 24a is housed in a sliding door of a car operation panel (not shown). The operation mode switching operation unit 24a is provided with a rescue operation switch (not shown), an independent operation switch (not shown), and a manual operation switch (not shown).

  The maintenance staff who has received the failure of the first elevator gets into the second car 24 waiting for door opening on the lobby floor and turns on the rescue operation switch. The operation mode switching operation unit 24a inputs a rescue operation command to the second control panel 21 when the rescue operation switch is turned on. When the second operation control unit 21b detects a rescue operation start signal, the second operation control unit 21b performs operation control in the rescue operation mode. When performing operation control in the rescue operation mode, the second operation control unit 21 b inputs a rescue operation start signal to the first control panel 11. When the first operation control unit 11b detects the rescue operation start signal, the first operation control unit 11b operates the safety circuit of the first car 14 to prevent the first car 14 from recovering from failure and starting during the rescue operation. enable. When detecting the rescue operation start signal, the first position calculation unit 11a inputs the stop position information indicating the stop position of the first car 14 to the second control panel 21 again.

  The machine room display unit 4 includes first and second machine room indicators 4a and 4b corresponding to the first and second elevators, respectively. The second determination unit 21d determines again whether or not the stop position of the first car 14 is within the unrecoverable area. If it is determined that it is outside the unrecoverable area, the first machine room indicator 4a, The rescueable lamps of the monitoring panel display 5d of 1 and the display 24b in the second car 24 are turned on. In addition, when the second determination unit 21d determines that the stop position of the first car 14 is outside the unrescueable area, the second determination unit 21d inputs a rescue operation permission signal to the second operation control unit 21b. A maintenance person who is in the second car 21 presses the door closing button on the car operation panel when the rescue enable lamp is lit. The second operation control unit 21b detects the rescue operation permission signal and, when detecting the completion of the door closing operation of the second car 24, travels the second car 24 to the stop position of the first car 14. Let

  In addition, when the rescue enable lamp is turned off, the maintenance staff turns on the independent operation switch of the operation mode switching operation unit 24a, turns off the rescue operation switch, and contacts the monitoring room manager through an intercom or the like. The second emergency call back switch 5c is turned off. The operation mode switching operation unit 24 a inputs an independent operation command to the second control panel 21 when the independent operation switch is turned on. The second operation control unit 21b detects the independent operation command and performs operation control in the independent operation mode when the rescue operation switch and the second emergency recall switch 5c are detected to be off. That is, the recall operation mode and the rescue operation mode are operation modes having higher priority than the independent operation mode.

  In the independent operation mode, the second operation control unit 21b dispatches the second car 24 according to the destination call registered on the second car operation panel. The maintenance staff moves to the top floor by the elevator after turning on the independent operation switch. Further, the maintenance staff moves from the top floor to the machine room 2 and runs the first car 14 to a position where there is no interference with the building beam 6. That is, the maintenance staff releases the brake of the first hoisting machine 10 and moves the first car 14 while confirming the display on the first machine room indicator 4a, or the first control panel 11 A driving operation terminal is connected to and the first operation car 14 is moved by operating the driving operation terminal. Further, the maintenance staff moves the first car 14 to a position where there is no interference with the building beam 6, and then turns on the rescue operation switch of the second car to perform rescue in the rescue operation.

  The registration operation unit 24c is for causing the first and second storage units 11c and 21c to store a non-rescueable area. The maintenance person gets into the second car 24 at the stage of installation adjustment, for example, and turns on the manual operation switch of the operation mode switching operation unit 24a. The operation mode switching operation unit 24 a inputs a manual operation command to the second control panel 21 when the manual operation switch is turned on. The second operation control unit 21b performs operation control in the manual operation mode when a manual operation command is detected. When the operation control is performed in the manual operation mode, the second operation control unit 21b causes the second car 24 to travel at a low speed between the upper and lower final floors according to the operation of the car operation panel by the maintenance staff. The maintenance staff monitors the positional relationship with the building beam 6 while running the second car 24 at a low speed, and operates the registration operation unit 24c according to the positional relationship. The registration operation unit 24c inputs a registration signal to the second storage unit 21c when being operated by a maintenance staff. The second storage unit 21c stores the car position obtained by the second position calculation unit 21a as a non-rescueable area when the registration signal is detected.

  Next, FIG. 3 is a side view showing the building beam 6 and the car 24 of FIG. 1 and is an explanatory diagram for explaining a rescue impossible area. In the figure, the car 24 is located where the lower end of the rescue door 3 (the lower end of the car 24) interferes with the upper end of the building beam 6. Moreover, as shown by a two-dot chain line in the figure, when the car 24 travels downward, the upper end of the rescue door 3 interferes with the lower end of the building beam 6. The maintenance staff memorizes the car position between the location where the lower end of the rescue door 3 interferes with the upper end of the building beam 6 and the location where the upper end of the rescue door 3 interferes with the lower end of the architectural beam 6 as an unrecoverable area. Store in the unit 21c. That is, the place where the lower end of the car 24 is located in the area A in the figure is the non-rescuable area, and the place located in the area B is the non-rescuable area. Here, the non-rescuable area of the first car 14 and the non-rescuable area of the second car 24 are the same. The second storage unit 21c transfers the stored non-rescueable area to the first storage unit 11c according to the operation of the maintenance staff. The first storage unit 11c stores the transferred rescue impossible area. In the above description, it has been described that the maintenance person gets into the second car 24 and first stores the non-rescueable area in the second storage unit 21c. However, the maintenance person gets into the first car 14 and first You may memorize | store a rescue impossible area in the memory | storage part 11c.

  In this embodiment, the car position detection means includes first and second position calculation units 11a and 21a and first and second encoders 12a and 22a. The operation control means includes first and second operation control units 11b and 21b. The storage means includes first and second storage units 11c and 21c. The determination means includes first and second determination units 11d and 21d. The display means is mounted on the first and second machine room indicators 4a and 4b, the first and second monitoring panel indicators 5d and 5e, the in-car indicator 24b, and the first car 14. Includes an in-car indicator. The registration means includes a registration operation unit 24c.

  Next, FIG. 4 is a flowchart showing a stop position determination operation performed by the second control panel 21 of FIG. In the figure, when a failure detection signal of the first elevator is detected by the second determination unit 21d, a stop position request signal is input from the second determination unit 21d to the first position calculation unit 11a. The stop position of the car 14 is input to the second determination unit 21d (step S10). At this time, based on the input stop position of the first car 14 and the non-rescueable area stored in the second storage unit 21c, is the stop position of the first car 14 within the non-rescueable area? Whether or not it is determined by the second determination unit 21d (step S11) and it is determined that it is out of the area where rescue is not possible, the rescueable lamp of the first monitoring panel display 5d is turned on (step S12). On the other hand, when it is determined that the stop position of the first car 14 is in the rescue impossible area, the rescue possible lamp of the first monitoring panel display 5d is turned off (step S13).

  Next, FIG. 5 is a flowchart showing operation control in the rescue operation mode performed by the second control panel 21 of FIG. In the figure, when the operation mode is switched to the rescue operation mode, a rescue operation start signal is input from the second operation control unit 21b to the first control panel 11, and the safety circuit of the first elevator is activated ( In step S20), the stop position of the first car 14 is input to the second determination unit 21d (step S21).

  At this time, based on the input stop position of the first car 14 and the non-rescueable area stored in the second storage unit 21c, is the stop position of the first car 14 within the non-rescueable area? No is determined by the second determination unit 21d (step S22), and when it is determined that the area is out of the unrescueable area, the first machine room display 4a, the first monitoring panel display 5d, and the second The rescue enable lamp of the in-car display 24b in the car 24 is turned on (step S23), and a rescue operation permission signal is input from the second determination unit 21d to the second operation control unit 21b. Next, whether or not the door closing operation of the second car 24 has been completed is determined by the second operation control unit 21b (step S24), and if it is determined that the door closing operation has been completed, The car 24 travels to the stop position of the first car 14 (step S25). On the other hand, when it is determined that the door closing operation has not been completed, the operation control in the rescue operation mode is terminated. This operation control is repeatedly performed while the operation mode is the rescue operation mode. That is, it is determined whether or not the door closing operation is completed when the operation mode remains in the rescue operation mode and the stop position of the first car 14 is outside the rescue impossible area. Repeat until. On the other hand, when it is determined that the stop position of the first car 14 is within the non-rescueable area, the car in the first machine room indicator 4a, the first monitoring panel indicator 5d, and the second car 24 The rescueable lamp of the inner display 24b is turned off (step S26).

  Next, FIG. 6 is a flowchart showing a passenger rescue method using the elevator rescue operation apparatus of FIG. Here, a case where the first elevator fails will be described. In the figure, when the failure of the first elevator is detected by the determination unit 11d of the control panel 11 and the abnormal buzzer 5a of the monitoring panel 5 is sounded, the sounding of the abnormal buzzer 5a is reset and the first monitoring panel It is confirmed whether or not the rescueable lamp of the display 5d is lit, and the emergency call back switch 5c is turned on (step S30). As a result, the operation mode is switched to the emergency call back mode, and the second car 24 is landed on the lobby floor.

  Next, the user enters the second car 24 and turns on the rescue operation switch of the operation mode switching operation unit 24a (step S31). As a result, the rescue operation mode has a higher priority than the recall mode, so the operation mode is switched to the rescue operation mode, and the second determination unit 21d determines whether or not the stop position of the first car 14 is within the unrescueable area. Let it be judged.

  Next, it is confirmed whether or not the rescueable lamp of the in-car display 24b is lit (step S32). If lit, the car door is closed and the second car 24 is moved to the first car. The car 14 is caused to travel to a stop position (step S33). When the second car 24 arrives at the stop position of the first car 14, the rescue door 3 of the first and second cars 14, 24 is opened and the first and second cars 14, 24 are opened. An evacuation ladder is placed between them to evacuate the passengers of the first car 14 (step S34).

  When the passenger evacuation is completed, the evacuation ladder is removed (step S35), the rescue door 3 is closed (step S36), and the rescue operation switch is turned off (step S37). As a result, the operation mode is again switched to the emergency call back mode, and the second car 24 is driven to the lobby floor. After the second car 24 arrives at the lobby floor, the passenger is lowered (step S38). Then, it moves to a monitoring room and turns off the emergency call back switch 5c. As a result, the operation mode is switched to the normal mode.

  On the other hand, when it is confirmed whether or not the rescueable lamp of the in-car display 24b is lit, if the rescueable lamp is turned off, the independent operation switch of the operation mode switching operation unit 24a is turned on ( In step S39), the rescue operation switch is turned off, and the supervisor in the monitoring room is contacted by an intercom or the like to turn off the second emergency call back switch 5c (step S40). Thereby, the operation mode is switched to the independent operation mode. The reason why the independent operation switch is turned on before turning off the rescue operation switch and the second emergency recall switch 5c is to switch to the normal operation mode when the rescue operation switch and the second emergency recall switch 5c are turned off. This is to prevent it.

  After the independent operation switch is turned on, the second car 24 is moved to the top floor and is moved to the machine room 2 to move the first car 14 (step S41). Specifically, the first car 14 is moved by releasing the brake of the first hoisting machine 10 or connecting a driving operation terminal to the first control panel 11 and operating the driving operation terminal. Let When the failure of the first elevator is a serious failure, the method of releasing the brake of the first hoisting machine 10 and moving the first car 14 is selected. At this time, while moving the first car 14, it is checked whether or not the rescueable lamp of the first machine room indicator 4a is lit (step S42). If the rescueable lamp is lit, the first The movement of the car 14 is terminated. Next, returning to the second car 24, the rescue operation switch is turned on (step S43) to switch to the rescue operation mode. Thereafter, the car door is closed, the second car 24 is caused to travel to the stop position of the first car 14, and passengers in the first car 14 are evacuated to the second car 24.

  In such an elevator rescue operation apparatus, the first and second determination units 11d and 21d are connected to the stop position of the failed elevator car calculated by the first and second position calculation units 11a and 21a and the first and second determination units. Since it is determined whether the stop position of the car 14 or 24 of the fault elevator is within the non-rescueable area based on the non-rescueable area stored in the storage units 11c and 21c of the second storage unit 11c or 21c. Using the encoders 12a and 22a used for operation control, it is possible to determine whether or not the cars 14 and 24 are located in the area where rescue cannot be performed, and use a detection device only for detecting the interference of obstacles. It is possible to eliminate the need to add to the top or in the hoistway, and to prevent the appearance from deteriorating. In addition, since optical detection equipment is not used to detect whether there is any interference from obstacles, the equipment cost and installation adjustment cost can be reduced, and cables etc. are not obstructed Can be reduced as an obstacle, and the possibility of malfunction can be reduced.

  Further, the first and second monitoring panel indicators 5d and 5e and the in-car indicator 24b for indicating whether or not the stop position of the car 14 or 24 of the failed elevator is within the area where rescue is not possible are the monitoring room and Since they are respectively arranged in the cars 14 and 24, it is possible to determine whether or not the rescue elevator can be rescued without laying the rescue elevator car 24 next to the car 14 of the failed elevator, and the rescue time can be shortened.

  Furthermore, since the first and second machine room indicators 4a and 4b are arranged in the machine room 2, the car 14 of the failed elevator is located in the non-rescueable area, and the car 14 is operated by the operation in the machine room 2. When the car is moved, it can be confirmed whether or not the car 14 has moved out of the non-rescueable area by the operation, and the convenience of the maintenance staff can be improved.

  Furthermore, the registration operation unit 24c stores the car position obtained by the position calculation units 11a and 21a in the storage units 11c and 21c as non-rescueable areas according to the operation of the maintenance staff. The area that cannot be rescued according to the situation can be stored in the storage units 11c and 21c, and the accuracy of determining whether or not the stop position of the cars 14 and 24 is within the area that cannot be rescued can be improved.

  In the first embodiment, the case where two elevators are provided is described. However, the present invention can also be applied to a multi-car provided with three or more elevators. For example, elevators of No. 1 to No. 3 are installed in order, and when No. 1 breaks down, No. 2 adjacent to No. 1 is used as a rescue elevator and No. 3 performs normal operation. At this time, even when the emergency call back operation mode is switched, the registered call assignment is changed to Unit 3, and a new call registration is also assigned to Unit 3.

  Moreover, although Embodiment 1 demonstrated that the hoisting machines 10 and 20 were arrange | positioned in the machine room 2, you may arrange | position in the hoistway. When the hoisting machine is placed in the hoistway, an indicator that displays whether the stop position of the car of the failed elevator is in the non-rescueable area is placed outside the hoistway where the hoisting machine can be operated remotely. You may arrange. That is, the display means may include an outside hoistway (landing) display.

  Further, in the first embodiment, the non-rescueable area is from the place where the lower end of the rescue door 3 interferes with the upper end of the building beam 6 to the place where the upper end of the rescue door 3 interferes with the lower end of the building beam 6. Although it was explained that it is the position of the car, the maintenance staff not only look at the positional relationship of the obstacles, the rescue door, and the evacuation ladder, but also consider the condition of whether the passenger can move safely Then, the rescue impossible area may be determined as appropriate.

It is a block diagram which shows the rescue operation apparatus of the elevator by Embodiment 1 of this invention. It is a block diagram which shows the rescue operation apparatus of the elevator of FIG. It is a side view which shows the building beam and cage of FIG. It is a flowchart which shows the stop position determination operation | movement which the 2nd control panel of FIG. 2 performs. It is a flowchart which shows the operation control in the rescue operation mode which the 2nd control panel of FIG. 2 performs. It is a flowchart which shows the passenger rescue method using the rescue operation apparatus of the elevator of FIG.
