Background technique

In recent years, with the increase in the height of buildings, the ultra-high speed of elevator apparatuses has been advanced. In such a high-speed elevator apparatus (hereinafter referred to as a super-high-speed elevator apparatus), the change in air pressure per unit time and the amount of change in total air pressure are large, and passengers often feel a sense of ear blockage due to the large air pressure change .

For this reason, in order to reduce such an ear-clogging feeling in the ultra-high-speed elevator apparatus, it has been proposed to mount an air pressure control device that controls the air pressure inside the car according to the air pressure outside the car. Here, in order to keep the internal air pressure of the car in an optimum state, it is necessary to improve the airtightness in the car.

However, when the airtightness of the car is improved, ventilation in the car cannot be performed in an emergency such as a power failure, and passengers who are confined in the car may suffer from oxygen deficiency. Therefore, conventionally, in the ultra-high-speed elevator apparatus, a ventilation window that is automatically opened in an emergency is provided, although it is normally closed.

In addition, Patent Document 1 discloses a configuration for automatically opening and closing a ventilator opening and closing member at the time of power failure and power recovery (normal normal power supply) in connection with the relevant ventilator. In addition, Patent Document 2 discloses that when the opening operation of the ventilating window device is not performed even after a predetermined ventilating window failure inspection period is exceeded, an opening command is given to the ventilating window device, and the opening command is performed according to whether or not the opening command is passed. The opening of the louver device is used to detect the failure or normality of the louver device.

The normal configuration unit 31 controls the ventilator device 13 in a normal time so that the ventilator opening/closing door 15 maintains the closed state of the door, while in an emergency, the ventilator device 13 is switched in accordance with an instruction given from the control unit 30 as described above in an emergency. The louver device 13 operates to open the louver opening and closing door 15 .

The integrity checking unit 32 is a functional unit having a function of properly checking the integrity of the ventilator device 13 (hereinafter referred to as a ventilator device integrity checking function). Actually, the integrity checking unit 32 checks the integrity of the ventilation window device 13 by operating the ventilation window device 13 to open and close the ventilation window opening and closing door 15, for example, at the following timing: When the car 2 keeps the door 11 closed and remains in the standby state for a long time without stopping on any floor for more than a given first time; after the final confirmation of the integrity of the ventilation window device 13, a period longer than the first time has elapsed. In the case of the given second time, the timing at which the car 2 will stop just before any floor.

As means for realizing the integrity checking function of such a ventilator device, the integrity checking unit 32 is provided with a soundness checking timing generating unit 33 , an elevator state detecting unit 34 , a ventilating window opening/closing operation unit 35 , and an operation checking unit 32 . unit 36 and abnormality monitoring unit 37 .

The integrity confirmation timing generation unit 33 has a function of generating a timing for confirming the integrity of the ventilation window device 13 . Specifically, the integrity confirmation timing generation unit 33 uses the first timer 22 ( FIG. 1 ) to measure the elapsed time since the car 2 stops at any floor, and when the car 2 stops at any floor with the door 11 closed. When the standby state has continued for a predetermined first time T1 (for example, 10 minutes), the ventilation window opening/closing operation unit 35 is notified of that fact. In addition, the integrity confirmation timing generation unit 33 uses the second timer 23 ( FIG. 1 ) to measure the elapsed time from the last confirmation of the integrity of the ventilator device 13 , and the elapsed time becomes a predetermined time sufficiently longer than the first time T1 When the 2nd time T2 (for example, 1 hour) is more than 1 hour, the elevator state detection part 34 is notified of this.

The ventilation window opening and closing operation unit 35 is notified from the integrity confirmation timing generation unit 33 that the waiting time of the car 2 has continued for the first time T1, or when instructed from the elevator state detection unit 34 to change the ventilation window device 13. The louver opening and closing door 15 is opened and closed at a predetermined timing, and the louver device 13 is controlled to open and close the louver opening and closing door 15 at the instructed timing.

The operation confirmation unit 36 monitors the opening and closing operation of the ventilator opening/closing door 15 of the ventilator device 13 under the control of the ventilator opening/closing operation unit 35 , and determines whether the opening/closing operation is normally performed. Then, when the operation confirmation unit 36 detects an abnormality in the opening/closing operation of the ventilator opening/closing door 15 , it outputs a notification of abnormality detection to the abnormality monitoring unit 37 .

The abnormality monitoring unit 37 transmits, for example, an abnormality detection notification to the control panel 3 via the control unit 30 to the control panel 3 when an abnormality detection notification is given from the operation confirmation unit 36 in the opening and closing operation of the ventilator opening and closing door 15 . As a result, based on the abnormality detection notification, the control panel 3 executes control processing at the time of predetermined abnormality detection, such as making the car 2 emergency stop on the nearest floor.

(2) Specific structural example of the ventilation window device

FIG. 3 is a cross-sectional view showing a specific configuration example of the ventilator device 13 viewed from the direction of arrow A in FIG. 1 . The ventilator device 13 includes a ventilator opening and closing door 15 rotatably arranged around the shaft 40 as a structure for opening or closing the ventilating opening k in an emergency when the power supply is cut off; The closing solenoid 41 for closing the louver opening and closing door 15; the casing 42 for fixing the closing solenoid 41 to the side panel 10A of the car 2; the opening and closing axis of the closing solenoid 41 A link mechanism 44 connecting one end of the 43 with the ventilator opening and closing door 15; The compression spring 45 is urged|biased in the direction away from the housing|casing 42 shown by arrow α2.

The link mechanism 44 converts the linear motion of the opening/closing shaft 43 of the closing solenoid 41 into the rotational motion of the ventilator opening/closing door 15 using an elongated hole or the like. In addition, as shown by the solid line in FIG. 3 , the opening and closing shaft 43 of the closing solenoid 41 moves in the direction of arrow α3 by the magnetic force of electromagnetic induction when the closing solenoid 41 is energized, thereby allowing ventilation. The window opening and closing door 15 rotates in the closing direction indicated by the arrow β2. On the other hand, when the closing solenoid 41 is de-energized, it moves in the direction of the arrow α2 by the elastic force of the compression spring 45. As shown by the two-dot chain line in FIG. 3 , the ventilation window opening/closing door 15 is rotated in the opening direction shown by the arrow β1.

In addition, the louver device 13 includes, as a mechanism for locking the door opening state of the ventilation opening k of the louver opening and closing door 15 , a locking solenoid 47 that causes one end portion of the lock shaft 46 to be locked. It is engaged with the ventilation window opening and closing door 15, thereby locking the ventilation window opening and closing door 15 in the closed state of the door; the housing 48, which fixes the locking solenoid 47 to the side panel 10A; and the compression spring 49, It is provided between the lock shaft 46 of the lock solenoid 47 and the housing 48 , and biases the engaging portion 46A provided on the other end side of the lock shaft 46 in the direction of separation from the housing 48 indicated by arrow α1 .

As shown by the solid line in FIG. 3 , the lock shaft 46 of the lock solenoid 47 moves in the direction of arrow α4 by the magnetic force of electromagnetic induction when the lock solenoid 47 is energized, thereby closing the door. The ventilator opening/closing door 15 is locked in this state. On the other hand, when the locking solenoid 47 is de-energized, the elastic force of the compression spring 49 moves in the direction of the arrow α1, so that as shown in FIG. As shown by the dashed-dotted line, it returns to the unlocked position which releases the lock of the ventilation window opening and closing door 15 .

In addition, the ventilator device 13 includes an operation switch 50 for turning on/off the power of the locking solenoid 47 and the closing solenoid 41 according to the open and closed state of the ventilator opening and closing door 15 . Actually, the operation switch 50 is composed of the following elements: a movable terminal 50A, which is freely movable in the directions of arrows ω1 and ω2, and is urged in the directions shown by arrows ω1; and a first terminal 50B, which is arranged such that When the louver opening and closing door 15 is in the door-closed state, it is pressed by the louver opening and closing door 15 and contacts the movable terminal 50A that moves in the direction of the arrow ω1; and the second terminal 50C, which It is arrange|positioned so that it may contact with the movable terminal 50A which moves in the direction of arrow (omega)1 by an urging force when the ventilation window opening/closing door 15 is in the door-open state.

Then, when the closing solenoid 41 is energized and the ventilating window opening and closing door 15 is normally closed, the movable terminal 50A of the operation switch 50 is in contact with the first terminal 50B, so that the movable terminal 50A of the operation switch 50 can be moved via the The terminal 50A and the first terminal 50B supply the drive current I ₁ to the locking solenoid 47 . As a result, since the locking solenoid 47 is energized and the locking shaft 46 moves in the direction of the arrow α4, the ventilator opening/closing door 15 is locked in the door-closed state.

In addition, since the movable terminal 50A is separated from the second terminal 50C at this time, the power supply to the closing solenoid 41 is not performed, and the closing solenoid 41 is powered off, thereby achieving power saving. Even when the closing solenoid 41 is turned off in this way, the ventilator opening and closing door 15 is locked in the door-closed state by the lock shaft 46 of the locking solenoid 47, so the ventilator opens and closes the door. The fan 15 does not open the door.

On the other hand, in an emergency (at the time of power failure), since the power supply to the locking solenoid 47 is cut off, the locking shaft 46 of the locking solenoid 47 is retracted as shown in FIG. 3 by the urging force of the compression spring 49 At the position of the two-dot chain line, the ventilation window opening and closing door 15 which has been locked in the door closed state by the locking solenoid 47 is in the unlocked state. As a result, the opening/closing shaft 43 of the closing solenoid 41 which is in the power-off state at this time is retracted to the position of the two-dot chain line by the elastic force of the compression spring 45, and is moved by the action of the link mechanism 44 accompanying this. The ventilation window opening and closing door 15 is rotated in the rotation direction indicated by the arrow β1, and the door is opened to the position indicated by the two-dot chain line. Thereby, the ventilation opening part k of the cage|basket|car 2 is opened, and ventilation of the inside of the cage|basket|car 2 is performed.

In addition, in the case of the present embodiment, in the louver device 13, when the door of the louver opening and closing door 15 is closed, the spacer 51 is provided between the louver opening and closing door 15 and the side panel 10A. . The spacer 51 is provided around the ventilation opening k of the side panel 10A, and closes the gap between the ventilation window opening and closing door 15 for closing the door and the side panel 10A. Thereby, when the door of the louver opening and closing door 15 is closed, the gasket 51 is in contact with the peripheral edge of the louver opening and closing door 15, and the ventilation window opening and closing door 15 and the opening for ventilation can be opened and closed. The airtight state of the car 2 is maintained between the side panels 10A around the portion k.

(3) The specific processing content of the integrity confirmation department

Next, regarding the confirmation of the integrity of the ventilation window device 13, a series of processes executed by the integrity confirmation unit 32 (FIG. 2) of the control device 4 (hereinafter referred to as the ventilation window device integrity confirmation process) will be described. process.

FIG. 4 shows a specific process flow of the related ventilation window device integrity confirmation process. When the operation of the elevator apparatus 1 is started, the integrity confirmation process of the ventilation window device is started. First, the integrity confirmation timing generation unit 33 determines that the car 2 is parked on any floor based on the count value of the first timer 22 ( FIG. 1 ). Whether the elapsed time since is more than the first time T1 (S1).

In addition, if a negative result is obtained in this determination, the integrity confirmation timing generation unit 33 determines whether or not the elapsed time since the integrity of the ventilation window device 13 was finally confirmed based on the count value of the second timer 23 ( FIG. 1 ). The second time T2 is exceeded (S2).

Then, if a negative result is obtained in this judgment, the integrity checking timing generation unit 33 returns to step S1, and thereafter repeats the loop of step S1-step S2-step S1 until a positive result is obtained in step S1 or step S2.

Then, when the completeness confirmation timing generation unit 33 finally obtains a positive result in step S2, it notifies the elevator state detection unit 34 of the fact, and when it obtains a positive result in step S1, notifies the ventilator opening of the fact. The closing action unit 35 is closed.

The elevator state detection unit 34 acquires the current state of the elevator apparatus 1 from the control panel 3 ( FIG. 2 ) via the control unit 30 ( FIG. 2 ) when notified from the integrity confirmation timing generation unit 33 , and based on the acquired elevator The timing at which the ventilator opening and closing door 15 should be opened and closed in order to confirm the integrity of the ventilator device 13 is calculated based on the current state of the device 1 (S3).

Specifically, the elevator state detection unit 34 acquires information such as the time until the car 2 stops at any floor next from the control panel 3 via the control unit 30, and based on the acquired information, calculates the time until the car 2 stops at the floor. The latest time from the current time when the opening and closing operation of the ventilation window opening and closing door 15 for confirming the integrity of the ventilation window device 13 is completed within the period until the opening and closing operation should be started (hereinafter referred to as the latest time point). It is called the final timing time).

In addition, when the elevator state detection unit 34 determines that the opening and closing operation of the ventilation window opening and closing door 15 cannot be completed until the car 2 stops at any of the next floors, it calculates the amount of time required until the car 2 stops at the next floor. The final timing time from the current point in which the opening and closing operation of the ventilation window opening and closing door 15 for confirming the integrity of the ventilation window device 13 is completed during the period up to the next floor, and the opening and closing operation should be started. .

Then, the elevator state detection unit 34 notifies the ventilation window opening/closing operation unit 35 of the final timing time calculated in this way.

When the ventilation window opening and closing operation unit 35 is notified from the integrity confirmation timing generation unit 33 that the elapsed time since the car 2 stops on any floor exceeds the first time T1, or is notified from the elevator state detection unit 34 At the final timing, just before the car 2 stops at any floor, the ventilation window opening and closing door 15 of the ventilation window device 13 is opened and closed (S4).

Specifically, the ventilation window opening/closing operation unit 35 immediately stops by, for example, when a notification is given from the integrity check timing generation unit 33 that the elapsed time since the car 2 stopped at any floor exceeds the first time T1. The supply of the driving current to the locking solenoid 47 described above in FIG. 3 releases the lock of the louver opening and closing door 15 by the locking solenoid 47 , thereby causing the louver opening and closing door 15 to open the door. Then, by supplying a drive current to the closing solenoid 41 , the ventilation window opening and closing door 15 is closed.

In addition, the ventilation window opening/closing operation unit 35 stops the supply of the drive current to the locking solenoid 47 at the timing when the final timing time has elapsed when the elevator state detection unit 34 is notified of the final timing time. The louver opening and closing door 15 is unlocked by the locking solenoid 47 to open the louver opening and closing door 15 , and then the louver is opened by supplying a drive current to the closing solenoid 41 . The door 15 is opened and closed to close the door.

At this time, the ventilation window opening and closing operation unit 35 monitors the contact of the movable terminal 50A to the first terminal 50B and the second terminal 50C in the operation switch 50 described above with respect to FIG. 3 , and then determines that the ventilation window opens and closes the door 15 Whether it is normally opened and closed (S5).

Then, when an affirmative result is obtained in this determination, the ventilator opening/closing operation unit 35 notifies the integrity check timing generation unit 33 of the fact. In this way, at this time, the integrity confirmation timing generation unit 33 executes the processing of step S1 and subsequent steps. Thus, the processing of steps S1 to S5 is repeated after that.

On the other hand, if a negative result is obtained in the determination of step S, the ventilator opening/closing operation unit 35 notifies the abnormality monitoring unit 37 that an abnormality has occurred in the opening and closing of the ventilator opening/closing door 15 . Then, the abnormality monitoring unit 37 executes a predetermined abnormality detection process when the relevant notification is given. Specifically, the abnormality monitoring unit 37 transmits a notification of abnormality detection to the control panel 3 via the control unit 30 when notified from the operation confirmation unit 36 that an abnormality has occurred during the opening and closing of the ventilator opening and closing door 15 . As a result, the control panel 3 executes the control processing at the time of predetermined abnormality detection such as stopping the car 2 at the nearest floor as described above.

In addition, in this case, the integrity checking unit 32 ends the ventilation window device integrity checking process after that. Therefore, after that, until the maintenance of the ventilator device 13 is performed, the confirmation of the integrity of the ventilator device 13 is not performed, and the operation of the elevator device 1 itself is also stopped.

(4) Effects of the present embodiment

As described above, in the elevator apparatus 1 of the present embodiment, when the car 2 has closed the door 11 and the car 2 is in a state where the car 2 has closed the door 11, when the waiting state in which any floor remains stationary for a long time exceeds the first time T1, or when such a long time When the waiting state for time exceeds the second time T2 which is sufficiently longer than the first time T1, the ventilator device 13 is actuated at the timing just before the car 2 stops at any floor to open and close the ventilator. 15 is opened and closed, thereby confirming the integrity of the ventilation window device 13 .

In this case, in the ultra-high-speed elevator apparatus, if the integrity check of the relevant ventilator device 13 is performed at an arbitrary timing, the ventilator opening and closing doors become difficult to open and close due to the influence of the upflow phenomenon. In some cases, it may be difficult to accurately confirm the integrity of the ventilator device 13 . In particular, when the door 11 ( FIG. 1 ) of the car 2 is opened, the ventilating window opening and closing door 15 of the ventilating window device 13 is opened, since the doors and windows of the elevator hall, the entrance and exit of the car 2, the interior of the car 2, and the ventilation Since wind flows through paths such as the opening k and the lift passage, the ventilation window opening and closing door 15 may not be closed in some cases.

In this regard, in the elevator apparatus 1 of the present embodiment, since the integrity of the ventilation window device 13 is checked at the timing when the door 11 of the car 2 is closed as described above, it is not affected by the upflow phenomenon and can be checked accurately. The integrity of the louver device 13 . In addition, in the elevator apparatus 1 of the present invention, since the ventilation window opening and closing door 15 is opened and closed while the car 2 is parked or during low-speed running before the stop, it can be compared with when the car 2 is being raised and lowered at a high speed. The integrity of the louver device 13 was confirmed in a state where the influence of the upflow was significantly reduced.

In addition, in the elevator apparatus 1, in order to confirm the integrity of the ventilation window device 13 at the relevant timing, even in the daytime when the operation frequency of the long-term standby does not occur, the car 2 can be raised and lowered immediately before the stop. By performing the relevant confirmation, the completeness of the ventilation window device 13 can be confirmed periodically or in a planned manner.

Furthermore, for example, when the completeness of the ventilation window device 13 is checked immediately before the car 2 starts, there is a possibility that the start of the car 2 may be inhibited due to slight imperfections. When the car 2 waits for a long time or just before a stop when the car 2 is running like the embodiment, the abnormality inspection of the ventilation window device 13 can be performed without reducing the operation efficiency of the elevator device 1 .
