BACKGROUND OF THE INVENTION
The present invention relates to an elevator operation control apparatus for controlling the control operation of an elevator installed in a building having a seismic isolation structure that absorbs a correlation displacement generated between a high-rise part and a low-rise part.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is an elevator operation control device that controls the control operation of an elevator installed in a building having a seismic isolation structure that absorbs a correlation displacement generated between a high-rise part and a low-rise part (see, for example, Patent Document 1). ). In such a base-isolated structure, there is a possibility that the hoistway guide rail of the part having the base isolation structure is distorted when an earthquake occurs. As shown in the earthquake control operation of the Elevator Association, the control operation at the time of the earthquake of the elevator is stopped by traveling to the nearest floor that can be stopped when an earthquake is detected during the travel. In addition, when there is a predetermined time or more to the nearest floor, a sudden stop is made on the spot. Further, after a sudden stop, the vehicle is driven at a low speed by an operation switch such as a monitoring panel. By doing in this way, an elevator can be operated safely, and when a shake of a building is detected by an earthquake or a typhoon, a passenger can be rescued safely and a sense of security can be given.

[Problems to be solved by the invention]
Most of current elevators use a system in which a car and a balance weight are moved up and down by a hoisting machine via a rope. In this type of elevator, not only the car but also the balance weight moves up and down along the hoistway guide rail. For this reason, when a building shake is detected due to an earthquake or typhoon, if the distortion of the hoistway guide rail of the seismic isolation structure is large, the balance weight will be detached from the guide rail when passing through the seismic isolation structure position. There is a danger of collision with the car if you continue running.
[0005]
The present invention has been made in view of the above points, and even in the case of detecting a shaking of a building in a base-isolated structure, the elevator can be operated safely, ensuring the safety of passengers and the balance of the car and the balance weight. It is an object of the present invention to obtain an elevator operation control device capable of preventing breakage.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
1 is a block diagram showing a configuration of an operation control apparatus for an elevator apparatus according to Embodiment 1 of the present invention. The operation control apparatus for an elevator apparatus shown in FIG. 1 includes an earthquake detector 1 that senses a shake of a building, an earthquake detection means 2 that detects a signal from the earthquake detector 1, and a position of the building. The seismic isolation structure position storage means 3 that stores in advance whether the base isolation structure is installed, the rope elongation detection device 4 that detects the elongation of the rope, and the car position when the balance weight is at the base isolation structure position When an earthquake is detected by the virtual seismic isolation structure position storage means 5 and the earthquake detection means 2 stored in advance, information on the nearest floor that can be stopped, the seismic isolation structure position storage means 3 and the virtual isolation structure position storage means 5 The car operation control means 6 for controlling the control operation at the time of the earthquake from the information of the above, and the alarm control means 7 for issuing an alarm, displaying or making an announcement in the manager's room or the car according to the operation state. ing.
[0008]
Here, the rope stretch detection device 4 and the virtual seismic isolation structure position storage means 5 are virtual seismic isolation structure position detection means for detecting the virtual seismic isolation structure position of the car when the balance weight is at the position of the seismic isolation structure. The virtual seismic isolation structure position storage means 5 is configured to change the stored virtual seismic isolation structure position when the rope elongation detected by the rope elongation detection device 4 exceeds a predetermined value. ing.
[0009]
FIG. 2 is an explanatory view showing the operation of the elevator. FIG. 2 shows a landing floor 10, an elevator car 11, and a balance weight 13. During traveling, the car travels while calculating the stoppable floor 12 from the speed and deceleration time. In this example, the seismic isolation structure 14 is set on the third floor, and the virtual seismic isolation structure 15 is set on the eighth floor.
[0010]
Next, the specific operation of the operation control apparatus for an elevator apparatus according to Embodiment 1 of the present invention will be described with reference to the flowchart shown in FIG. The basic operation is based on the Elevator Association's earthquake control operation. First, the seismic detector 1 to be detected differs depending on the sensitivity of the earthquake to be stopped, and this is judged by the earthquake detecting means 2 (steps S1 and S2). In the example shown in FIG. 1, as the earthquake detector 1, an earthquake detector that detects an earthquake exceeding an extra low sensitivity, an earthquake detector that detects an earthquake exceeding an extra low sensitivity and an even lower sensitivity, It has an earthquake detector that detects earthquakes exceeding the sensitivity of. If the earthquake has an extra low sensitivity, the process proceeds to step S3 and normal operation is continued. On the other hand, if the earthquake exceeds the low sensitivity and the sensitivity is low, step S4 and subsequent steps are executed. If the earthquake exceeds the low sensitivity and the sensitivity is low, step S13 and subsequent steps are executed.
[0011]
In step S4, the operation state of the elevator is determined. If the vehicle is running, the process proceeds to step S5. In step S5, it is determined whether there is a seismic isolation structure 14 or a virtual seismic isolation structure 15 between the stoppable floor 12 where the car can be stopped and the car position 11, and in the case shown in FIG. When there is the structure part 15, it progresses to step S6 and makes an emergency stop of an elevator. In other cases, the normal seismic control operation specified by the Elevator Association is performed.
[0012]
Here, the rope 16 that connects the car and the balance weight 13 tends to extend due to secular change. When the rope elongation reaches a predetermined value or more by the rope elongation detecting means 4 in FIG. 1, the position of the virtual seismic isolation structure 15 is changed to the seventh, eighth, and ninth floors up to the upper and lower floors of the eighth floor. Thereby, the entry range to the seismic isolation structure position of the balance weight 13 by the rope elongation in step S5 can be widened, and the safety when the shaking of the building is detected can be ensured.
[0013]
In normal seismic control operation, if it does not enter the seismic isolation structure position or the virtual seismic isolation structure position in step S5, the process proceeds to step S7, for example, whether the car travels for 10 seconds or more before stopping at the nearest floor. Judging. If it takes 10 seconds or more, the process proceeds to step S6, and the elevator is stopped emergencyly. If it is within 10 seconds, the process proceeds to step S8 and stops at the nearest floor.
[0014]
After stopping at the nearest floor, the car door is opened in step S9 and the passengers are lowered. If the car is not traveling in step S4, the process proceeds to step S9. Then, after a predetermined time has passed in step S10, the car door is closed. If a passenger who has not yet got off in step S11 presses the door open button, the process returns to step S9. However, unless the door open button is pressed from within the car, in step S12, the passenger is put in a state where no passenger is in the car and the operation is suspended.
[0015]
If the low-sensitivity seismic detector does not operate in step S2, the process proceeds to step S13 to determine whether the elevator car is traveling. If the car is running, the car is stopped at the nearest floor in step S14, the car door is opened in step S15, and the passenger is lowered. If the car is not traveling in step S13, the process proceeds to step S15. Thereafter, the door of the car is closed after a predetermined time has passed in step S16. If a passenger who has not yet got off in step S17 presses the door open button, the process returns to step S15. However, as long as the door open button is not pressed from within the car, the operation is suspended as there is no passenger. If the seismic detector with extra low sensitivity is automatically or manually reset in step S18, normal operation is resumed in step S19.
[0016]
Next, FIG. 4 is a flowchart showing a procedure after an emergency stop. After the emergency stop, proceed to step S20 to check various safety circuits. If it is safe, proceed to step S21 to determine whether or not an earthquake sensor having a high sensitivity (predetermined value) or more has been operated. To do. If a seismic detector having a high sensitivity or higher operates, the process proceeds to step S22, and it is determined whether the position where the car has stopped is the seismic isolation structure position or the virtual seismic isolation structure position. Here, if the car has stopped at the seismic isolation structure position, the process proceeds to step S23, where an alarm is given to the manager room and the maintenance company, and the passengers in the car are displayed and notified that the elevator is suspended. Then, it progresses to step S24 and an elevator stops driving | operation. If the stop position of the car is not the seismic isolation structure position or the virtual seismic isolation structure position in step S22, the process proceeds to steps S25, S26, and S27, and the rescue operation is started. If a seismic detector with high sensitivity (predetermined value) or higher does not operate in step S21, the vehicle automatically runs at a low speed (for example, 45 m / min) in the direction in which the car and the weight are separated after about 1 minute. Stop on the floor.
[0017]
Furthermore, FIG. 5 is a flowchart showing the operation during the rescue operation. In step S30, it is determined whether the stop position of the car is above or below the intermediate position. If the car position is above the intermediate position, the process proceeds to step S31, the nearest floor in the UP direction is searched, and the nearest car position is reached. It is determined whether or not the vehicle passes through the virtual seismic isolation structure position while traveling to the floor. When it passes, it progresses to step S32 and the driving condition of a DN (down) direction is judged. In step S32, when the car is moved downward and stopped at the nearest floor, it is determined whether or not it is necessary to drive beyond the position where the car and the weight do not intersect (intermediate position). When it crosses, it progresses to Step S33 and stops an elevator in a stop state. If it does not exceed the intermediate floor, the process proceeds to step S38, and the elevator travels in the DN direction. If there is no virtual seismic isolation structure position in the UP travel direction in step S31, the UP direction is set in step S34 and the elevator travels. When the stop position of the car is below the intermediate floor, the reverse operation is performed (steps S35, S36, S37, S34).
[0018]
