Description

Elevator and elevator operation method

The present invention relates to an elevator in which a long object such as a rope or a cable moves in accordance with the movement of a car, and an operation method of the elevator.

In conventional elevators, the main rope that suspends the car and the counterweight swings greatly in the event of an earthquake, so that the main rope will not hit the wall of the hoistway. The main rope of the elevator that is stored in the storage box at the top of the hoistway with the wires connected to each other, and when the seismic detector detects an earthquake, a plurality of steadying plates are dropped from the storage box A steady rest device is known. The plurality of steadying plates dropped from the storage box hang down while maintaining a certain distance along the main rope while being connected by wires. As a result, the main rope is surrounded by a plurality of steadying plates, and the main rope is prevented from hitting the wall surface of the hoistway even if the main rope swings greatly during an earthquake (see Patent Document 1).

JP-A-11-171424

However, in such a conventional elevator main rope steady rest device, a plurality of steady rest plates only hang down along the main rope while maintaining a certain distance. The plate for use also swings greatly, making it difficult to suppress the swing width of the main rope. In particular, at the position where the main rope vibration occurs, there is no means for stopping the main rope swing, so it is difficult to suppress the swing width of the main rope. Therefore, the main rope and the steadying plate may interfere with the car and the like, and the car may be damaged or the main rope and the steadying plate may be caught on the cage.

The present invention has been made to solve the above-described problems, and provides an elevator that can make it difficult for long objects to interfere with a car when a building shakes, and an elevator operation method. The purpose is to obtain.

The elevator according to the present invention includes a car that can move up and down in the hoistway, a car position detecting device that detects the position of the car, a long object that moves in accordance with the movement of the car in the hoistway, and the movement of the car. The long object has an inter-fulcrum part that reaches from one of two fulcrum points away from each other, and the central part in the length direction of the inter-fulcrum part has a large amplitude prediction. The position of the car when the position of the car and the position of the large amplitude prediction part are at the same height is the interference prediction position, and the control device detects the shaking of the building with a sensor. When this is done, the car is stopped at the avoidance position that is out of the predicted interference position based on the information from the car position detection device.

The elevator operation method according to the present invention is a method of operating an elevator in which a long object having a portion between fulcrums reaching one from two fulcrums separated from each other moves in accordance with the movement of the car. The center part in the length direction of the part between the fulcrums is the large amplitude prediction part, and the position of the car when the position of the car and the position of the large amplitude prediction part are at the same height is set as the interference prediction position. When the movement of the car is detected by the sensor, the control device stops the car at the avoidance position that deviates from the predicted interference position based on the information from the car position detection device that detects the car position.

According to the elevator and the operation method of the elevator according to the present invention, when the building shakes, the car is stopped at the avoidance position deviated from the interference prediction position, so that the long object is less likely to interfere with the car. it can.

Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an elevator according to Embodiment 1 of the present invention. In the figure, a car 2 and a counterweight 3 are provided in the hoistway 1. The car 2 can move up and down in the hoistway 1 while being guided by a pair of car guide rails (not shown) installed in the hoistway 1. The counterweight 3 is movable in the vertical direction while being guided by a pair of counterweight guide rails (not shown) installed in the hoistway 1. The moving path of the car 2 and the moving path of the counterweight 3 are adjacent to each other in the horizontal direction.

A hoisting machine 4 that generates a driving force for moving the car 2 and the counterweight 3 is installed at the upper part of the hoistway 1. The hoisting machine 4 has a driving sheave 5. The driving sheave 5 is rotated by the driving force of the hoisting machine 4. A suspension body 6, which is a long object for suspending the car 2 and the counterweight 3, is wound around the driving sheave 5. For example, a rope or a belt is used as the suspension body 6. In this example, one end of the suspension body 6 is connected to the upper portion of the car 2, and the other end portion of the suspension body 6 is connected to the upper portion of the counterweight 3. That is, in this example, the hanging method of the car 2 and the counterweight 3 is a 1: 1 roping method. Thereby, the suspension body 6 is stretched between each of the car 2 and the counterweight 3 and the drive sheave 5. When the driving sheave 5 rotates, the car 2 moves up and down in the hoistway 1, and the counterweight 3 moves in a direction opposite to the moving direction of the car 2 according to the movement of the car 2. The suspension body 6 moves according to the movement of the car 2 and the counterweight 3.

The suspension body 6 includes a fulcrum portion 6 a between the cab 2 and the driving sheave 5, and a fulcrum 6 on the counterweight 3 side that exists between the counterweight 3 and the driving sheave 5. And an interstitial region 6b. The fulcrum portion 6 a on the car 2 side reaches from one of two fulcrums located on the car 2 and the driving sheave 5 to the other. The fulcrum portion 6b on the counterweight 3 side reaches from one of two fulcrums located on the counterweight 3 and the drive sheave 5 to the other. The length of each fulcrum part 6a, 6b changes according to the movement of the car 2 and the counterweight 3.

Between the car 2 and the counterweight 3, a balance rope 7, which is a long object that compensates for the balance of balance between the car 2 side and the counterweight 3 side, is suspended. One end of the balancing rope 7 is connected to the lower part of the car 2, and the other end of the balancing rope 7 is connected to the lower part of the counterweight 3. At the lower part of the hoistway 1, a balancing rope tensioning wheel 8 is provided. A balancing rope 7 is wound around the balancing rope tensioning vehicle 8. The balancing rope 7 is stretched between each of the car 2 and the balancing weight 3 and the balancing rope tensioning vehicle 8. The balancing rope 7 moves in accordance with the movement of the car 2 and the balancing weight 3.

The balancing rope 7 is a balance between the fulcrum part 7a on the side of the car 2 that exists between the car 2 and the balancing rope tensioning car 8, and between the counterweight 3 and the balancing rope tensioning car 8. And a portion 7b between fulcrums on the weight 3 side. The fulcrum part 7a on the car 2 side reaches from one of two fulcrum points located on the car 2 and the balancing rope tensioning wheel 8 to the other. The portion 7b between the fulcrums on the counterweight 3 side reaches from one of two fulcrums located on the counterweight 3 and the balance rope tension wheel 8 to each other. The length of each fulcrum part 7a, 7b changes according to the movement of the car 2 and the counterweight 3.

An emergency stop device 9 is provided at the bottom of the car 2. The emergency stop device 9 is provided with an operating lever. When the operation lever is operated, the emergency stop device 9 grips the car guide rail and applies a braking force to the car 2.

A governor 10 is provided at the upper part of the hoistway 1, and a governor tensioner 11 is provided at the lower part of the hoistway 1. The governor 10 includes a governor sheave 12. A governor rope 13, which is a long object, is wound around the governor sheave 12 and the governor tension wheel 11. One end and the other end of the governor rope 13 are connected to an operating lever of the safety device 9. The governor rope 13 is stretched in a loop between the governor sheave 12 and the governor tension wheel 11. The governor rope 13 moves according to the movement of the car 2 while rotating the governor sheave 12 and the governor tension wheel 11.

For example, when the speed of the car 2 rises abnormally for some reason, such as when the suspension body 6 breaks, and the speed of the car 2 reaches the emergency stop excessive speed, the speed governor 10 grips the speed governor rope 13. Thereby, the car 2 is displaced with respect to the governor rope 13 and the operating lever of the safety device 9 is operated. Thereby, a braking force is applied to the car 2.

The governor rope 13 is located between the upper fulcrum part 13 a existing between the car 2 and the governor sheave 12, and the lower fulcrum existing between the car 2 and the governor tensioner 11. It has the site | part 13b and the site | part 13c between the fulcrum of the upper and lower sides which exist between the governor sheave 12 and the governor tension wheel 11. The upper fulcrum portion 13a reaches from one of two fulcrums located on the car 2 and the governor sheave 12 to the other. The lower fulcrum portion 13b reaches from one of two fulcrums located on the car 2 and the governor tensioner 11 to the other. The portions 13c between the upper and lower fulcrums reach from one of two fulcrums located on the governor sheave 12 and the governor tension wheel 11 to the other. The lengths of the portions 13a and 13b between the fulcrums change according to the movement of the car 2 and the counterweight 3. The length of the part 13c between fulcrums does not change even if the car 2 and the counterweight 3 move.

The governor sheave 12 and the governor tension wheel 11 rotate according to the movement of the car 2. The speed governor sheave 12 is provided with a speed governor encoder 14 that is a car position detecting device that generates a signal corresponding to the rotation of the speed governor sheave 12. The governor encoder 14 detects the position and speed of the car 2 by generating a signal corresponding to the rotation of the governor sheave 12. A control device (not shown) for controlling the operation of the elevator is installed in the hoistway 1. Information from the governor encoder 14 is sent to the control device.

A repeater 15 is fixed to the middle part of the hoistway 1 in the vertical direction. A control cable 16 that is a long object is connected between the repeater 15 and the car 2. The control cable 16 moves in the hoistway 1 according to the movement of the car 2.

The control cable 16 has a drooping portion that hangs only by its own weight between the car 2 and the relay 15 as a fulcrum portion 16a. The inter-fulcrum portion 16a reaches from one of two fulcrums located in each of the car 2 and the relay 15 to the other. The length of the inter-fulcrum portion 16a does not change even when the car 2 moves.

Information is sent via the control cable 16 between the car control panel provided in the car 2 and the control device. The control device controls the operation of the elevator based on information from the car control panel and the governor encoder 14.

In the hoistway 1, although not shown, for example, landing sensors on each floor, landing door devices on each floor, car guide rails, brackets that support the counterweight guide rails, and the like are installed as a plurality of hoistway devices. ing.

Here, for example, when the building is shaken by an earthquake or a strong wind, the long objects such as the suspension body 6, the balancing rope 7, the governor rope 13 and the control cable 16 are shaken in the horizontal direction along with the shaking of the building. . When each long object is swinging, the vibration antinodes of the inter-fulcrum sites 6a, 6b, 7a, 7b, 13a, 13b, 13c, 16a (hereinafter referred to as “the inter-fulcrum sites 6a to 16a”) It is predicted that the amount of displacement of each long object in the horizontal direction will increase at the position. The position of the antinode of the vibration in the primary mode of the inter-fulcrum site is the central portion in the length direction of the inter-fulcrum site. Accordingly, the central portion in the length direction of each inter-fulcrum portion 6a to 16a is a large amplitude predicting portion where the amplitude in the horizontal direction is predicted to increase.

Moreover, since the part 16a between the fulcrums of the control cable 16 is a hanging part that hangs down only by its own weight between the car 2 and the relay 15, when the control cable 16 swings, It is predicted that not only the amount of displacement in the central portion in the horizontal direction but also the amount of displacement in the horizontal direction of the lower end of the inter-fulcrum portion 16a is increased. Therefore, in the control cable 16, the central part in the length direction of the inter-fulcrum part 16a and the lower end part of the inter-fulcrum part 16a are large amplitude predicting parts.

The positions of the large-amplitude predictors of the inter-fulcrum sites 6a, 6b, 7a, 7b, 13a, 13b, 16a (hereinafter referred to as “the inter-fulcrum sites excluding the inter-fulcrum site 13c”) are the car 2 and the balance. It moves up and down according to the movement of the weight 3. On the other hand, the position of the large amplitude prediction portion of the inter-fulcrum portion 13c does not move even when the car 2 and the counterweight 3 move.

If there is the car 2 at the height of the position of each large amplitude prediction portion of each of the inter-fulcrum parts 6a to 16a, the possibility that the large amplitude prediction part of the inter-fulcrum part will interfere with the car 2 increases. Therefore, the position of the car 2 when it is at the same height as the position of the large amplitude prediction portion of each of the inter-fulcrum parts 6a to 16a is an interference predicted position where each long object and the car 2 are likely to interfere with each other. ing.

Similarly, the position of the car 2 when the position of the large-amplitude prediction unit and the position of the counterweight 3 are at the same height in each inter-fulcrum portion 6a to 16a is the same as that of each long object and the counterweight 3 Is an interference prediction position where there is a high possibility of interference. Further, the position of the car 2 when the position of the large amplitude prediction unit and the position of the equipment in the hoistway are at the same height in each inter-fulcrum part 6a to 16a is that the long objects and the equipment in the hoistway interfere with each other. It is an interference prediction position that is highly likely to occur.

Further, among the inter-fulcrum parts 6a to 16a, the car 2 when the position of the large amplitude predicting part of one inter-fulcrum part and the position of the large amplitude predicting part of the other inter-fulcrum part are at the same height. This position is an interference prediction position where there is a high possibility that the portions between one and the other fulcrum will interfere with each other.

FIG. 2 is a schematic diagram showing a state in which the suspension body 6 and the balancing rope 7 are swaying when the car 2 is at an interference predicted position determined by the relationship between the fulcrum portion 6b of the suspension body 6 in FIG. It is. FIG. 3 shows a state in which the suspension body 6 and the balancing rope 7 are swaying when the car 2 is at the interference prediction position determined by the relationship between the fulcrum portion 7b of the balancing rope 7 of FIG. It is a schematic diagram shown. When the car 2 is at an interference predicted position determined by the relationship between the car 2 and the inter-fulcrum part 6b, the vibration antinodes of the inter-fulcrum part 6b are likely to interfere with the car 2, as shown in FIG. Further, when the car 2 is located at an interference predicted position determined by the relationship between the car 2 and the inter-fulcrum part 7b, the vibration antinode of the inter-fulcrum part 7b easily interferes with the car 2, as shown in FIG.

The control device includes a relationship between the car 2 and each fulcrum part 6a to 16a, a relationship between the counterweight 3 and each fulcrum part 6a to 16a, each fulcrum part excluding the fulcrum part 13c and the equipment in the hoistway. And a plurality of predicted interference positions determined by each of the relations between one of the fulcrum sites 6a to 16a and the other are preset as table information. The predicted interference positions are the lengths of the long objects 6, 7, 13, 16, the driving sheave 5, the balancing rope tension wheel 8, the governor sheave 12, the governor tension wheel 11, and the relay 15 Is calculated in advance at the design stage of the elevator from the relationship between the positions of the car 2 and the positions of the car 2 and the counterweight 3.

The building where the elevator is installed may shake, for example, due to strong winds or earthquakes. The building is provided with a sensor (not shown) that detects the shaking of the building when the shaking of the building becomes larger than a set value. Information from the sensor is sent to the controller. When the shaking of the building is detected by the sensor, the control device stops the car 2 at the avoidance position deviated from each interference prediction position based on the information from the governor encoder 14.

That is, the control device calculates the position, speed, and moving direction of the car 2 based on the information from the governor encoder 14 when the shaking of the building is detected by the sensor, and the calculated position of the car 2 Then, the car 2 is stopped at the avoidance position deviated from each interference prediction position based on the speed and moving direction and each interference prediction position preset as table information.

Next, we will explain how to operate the elevator when the shaking of the building is detected by the sensor. When the shaking of the building is detected by the sensor, the control device calculates the position, speed, and moving direction of the car 2 based on information from the governor encoder 14, and determines whether the car 2 is stopped. Determine. The control device may determine whether or not the car 2 is stopped using a command speed for controlling the speed of the car 2.

Thereafter, when it is determined that the car 2 is stopped, the control device compares the stop position of the car 2 with each interference predicted position, and whether the car 2 is stopped at any one of the predicted interference positions. Determine whether. When it is determined that the stop position of the car 2 is an avoidance position deviating from the predicted interference position, the control device maintains the state where the car 2 is stopped without moving the car 2. On the other hand, when it is determined that the car 2 is stopped at the predicted interference position, the control device moves the car 2 and stops the car 2 at an avoidance position that is out of the predicted interference position.

Further, when the control device determines that the car 2 is moving when the shaking of the building is detected by the sensor, the position, speed, and movement of the car 2 calculated from the information from the governor encoder 14. Based on the direction and each predicted interference position set as table information, it is determined whether or not the car 2 can be stopped from the current position of the car 2 to the nearest predicted interference position. At this time, the control device calculates the stop position of the car 2 by calculating a delay time from when the braking command is given to the car 2 to when it is actually stopped based on the calculated speed of the car 2.

When the car 2 can be stopped before the nearest predicted interference position, the control device immediately stops the car 2 at the avoidance position located before the nearest predicted interference position. On the other hand, when the car 2 cannot be stopped by the closest predicted interference position, the control device 2 determines the interference predicted position closest to the current position of the car 2 and the current position of the car 2 from the current position. The car 2 is stopped at the avoidance position, with the intermediate position between the interference prediction position closest to the second position as the avoidance position. In this way, by stopping the car 2 at the avoidance position deviated from each interference prediction position, each of the car 2, the counterweight 3 and the equipment in the hoistway and each of the long objects 6, 7, 13, 16 Interference is less likely to occur, and interference between the long objects 6, 7, 13, 16 is less likely to occur.

In such an elevator, the central portion in the length direction of each inter-fulcrum portion 6a to 16a of each of the long objects 6, 7, 13, 16 that moves according to the movement of the car 2 is a large amplitude predicting unit. At the same time, the position of the car 2 when the position of the car 2 and the position of the large amplitude predicting unit are at the same height is the interference predicting position, and the control device detects the shaking of the building by the sensor. Further, since the car 2 is stopped at the avoidance position deviated from the predicted interference position based on the information from the governor encoder 14, the horizontal direction of each of the long objects 6, 7, 13, 16 when the building is shaken The car 2 can be stopped while avoiding the position where the amount of displacement to becomes large. Accordingly, when the building shakes, the long objects 6, 7, 13, 16 can be prevented from interfering with the car 2, and the long objects 6, 7, 13, 16, and the car 2 The occurrence of each damage can be suppressed. In addition, it is possible to prevent the long objects 6, 7, 13, and 16 from being caught by the car 2, and the return operation after the shaking of the building is eliminated can be facilitated in a short time.

In addition, the control cable 16 that is a long object has a hanging portion that hangs down between two fulcrums as a fulcrum portion 16a, not only the central portion in the length direction of the fulcrum portion 16a of the control cable 16, Since the lower end portion of the inter-fulcrum portion 16a of the control cable 16 is also a large amplitude predicting portion, it is possible to more reliably prevent the control cable 16 from interfering with the car 2 when the building shakes.

Further, the position of the car 2 when the position of the counterweight 3 and the position of the large amplitude predicting portion of each of the long objects 6, 7, 13, 16 are at the same height is the interference predicted position. When the building shakes, the long objects 6, 7, 13, 16 can be prevented from interfering with not only the car 2 but also the counterweight 3.

In addition, the position of the car 2 when the position of the equipment in the hoistway and the position of the large amplitude prediction unit of each of the long objects 6, 7, 13, 16 are at the same height is the interference prediction position. When the building shakes, the long objects 6, 7, 13, 16 can be made difficult to interfere with not only the car 2 but also the equipment in the hoistway.

Further, there are a plurality of inter-fulcrum sites 6a to 16a in the hoistway 1, and the position of the large amplitude predicting unit at one inter-fulcrum site and the position of the large amplitude predicting unit at the other inter-fulcrum site Since the position of the car 2 when they are at the same height is the interference prediction position, the long objects 6, 7, 13, 16 can be made difficult to interfere with each other.

Further, in such an elevator operation method, the position of the car 2 when the position of the large amplitude predicting portion of each of the long objects 6, 7, 13, 16 and the position of the car 2 are at the same height is predicted to interfere. When the building is shaken, the car 2 is stopped at the avoidance position outside the predicted position of interference when the shake of the building is detected by the sensor. Therefore, when the building is shaken, the long objects 6, 7, 13, 16 The car 2 can be stopped avoiding the position where the amount of displacement in the horizontal direction becomes large. Accordingly, when the building shakes, the long objects 6, 7, 13, 16 can be prevented from interfering with the car 2, and the long objects 6, 7, 13, 16, and the car 2 The occurrence of each damage can be suppressed. Further, it is possible to prevent the long objects 6, 7, 13, and 16 from being caught by the car 2, and the return operation after the shaking of the building is eliminated can be facilitated in a short time.

Embodiment 2. FIG.
In the first embodiment, when the movement of the car 2 is detected by the sensor, the car 2 is not stopped at the nearest floor, but the car 2 is temporarily stopped at the nearest floor. Thereafter, the car 2 may be stopped at the avoidance position.

That is, when the shaking of the building is detected by the sensor, the control device calculates the position, speed and moving direction of the car 2 based on the information from the governor encoder 14, and whether the car 2 is stopped. Determine whether or not. Thereafter, when it is determined that the car 2 is moving, the control device temporarily stops the car 2 to the nearest floor and brings the car 2 into the door open state. Thereby, passengers in the car 2 can get off at the landing on the nearest floor. Thereafter, the control device places the car 2 in the door-closed state, then moves the car 2 and stops the car 2 at the avoidance position. Other configurations and operations are the same as those in the first embodiment.

In such an elevator, when the swing of the building is detected by the sensor, the control device stops the car 2 at the nearest floor and then stops the car 2 at the avoidance position. When the building shakes, the passengers can be evacuated from the car 2 to the nearest floor, and the passengers can be prevented from being trapped in the car 2.

In the above example, the control device moves the car 2 to the avoidance position regardless of the presence or absence of passengers in the car 2 after stopping the car 2 at the nearest floor. A passenger detection device for detecting whether or not a passenger is in the vehicle is provided, and the control device confirms that the passenger has got off the car 2 from the car 2 based on information from the passenger detection device. You may make it move to an avoidance position. In this case, as the passenger detection device, for example, a camera for photographing the inside of the car 2 or a scale device for measuring a load in the car 2 is used.

Embodiment 3 FIG.
In the second embodiment, when the shaking of the building is detected by the sensor, the control device temporarily stops the car 2 at the nearest floor regardless of whether a passenger is in the car 2 or not. The control device may stop the car 2 at the nearest floor only when a passenger is in the car 2 when the shaking is detected by the sensor.

That is, in this embodiment, a passenger detection device that detects whether or not a passenger is in the car 2 is provided. As the passenger detection device, for example, a camera for photographing the inside of the car 2, a scale device for measuring the load in the car 2, a car control panel provided with a plurality of destination floor buttons, and the like are used. In the car control panel, whether or not a passenger is in the car 2 is detected based on whether or not the destination floor is registered by operating the destination floor button. Information from the passenger detection device is sent to the control device.

When it is determined that the car 2 is moving based on the information from the governor encoder 14 when the shaking of the building is detected by the sensor, the control device determines the car based on the information from the passenger detection device. It is determined whether or not 2 is stopped at the nearest floor. That is, when the swing of the building is detected by the sensor during the movement of the car 2, if the passenger is in the car 2, the control device stops the car 2 at the nearest floor and the passenger stops the car 2. If it is not inside, the car 2 is stopped at the avoidance position regardless of the position of the nearest floor.

When the passenger is in the car 2, the control device stops the car 2 at the nearest floor, opens the car 2 and opens the passenger from the car 2 to the nearest floor, The car 2 is moved, and the car 2 is stopped at the avoidance position. When the position of the car 2 stopped at the nearest floor is the avoidance position, the control device maintains the stopped state of the car 2 without moving the car 2. Other configurations are the same as those of the second embodiment.

In such an elevator, if a passenger is in the car 2 when the shaking of the building is detected by the sensor, the control device avoids the car 2 after stopping the car 2 on the nearest floor. When the passenger is not in the car 2, the control device stops the car 2 at the avoidance position regardless of the position of the nearest floor, so that when the building shakes, the car 2 Each long object 6, 7, 13, 16 can be made difficult to interfere with the cage | basket | car 2, avoiding that a passenger is confined inside.

Embodiment 4 FIG.
In the first embodiment, the priority order of each interference predicted position is not set, but the priority order determined from the viewpoint of the damage level may be set to each interference predicted position.

That is, FIG. 4 is a table showing the degree of damage when the elevator car 2, the counterweight 3, the hoistway equipment and the long objects interfere with each other according to the fourth embodiment of the present invention. . When the car 2, the counterweight 3 or the equipment in the hoistway and the long objects 6, 7, 13, 16 interfere with each other, for example, the long object is caught on a protrusion of a sensor or an electronic component. If the protrusion is damaged or the long object remains caught, the operation of the elevator cannot be continued. Therefore, the damage degree when the car 2, the counterweight 3 or the hoistway device and the long objects 6, 7, 13, 16 interfere with each other is set to a high level display "1". . On the other hand, when the long objects 6, 7, 13, and 16 interfere with each other, there is a low possibility that they will be caught. Therefore, the damage level when the long objects 6, 7, 13, and 16 interfere with each other is displayed as “2” as a level lower than the display “1”. In FIG. 4, a display “-” is shown for a relationship in which the possibility of interference with each other is extremely low, or the possibility of damage occurring even if they interfere with each other is extremely low.

The damage degree corresponding to each interference predicted position is set in advance in the control device. That is, the priority determined from the viewpoint of the degree of damage is set in the control device corresponding to each predicted interference position. When the shaking of the building is detected by the sensor, the control device determines an avoidance position for stopping the car 2 based on the priority order corresponding to each interference predicted position. Specifically, when stopping the car 2 at the avoidance position between two adjacent interference prediction positions, the control device determines the avoidance position so as to be far from the interference prediction position with the higher damage level. In other words, in this example, the control device detects from the interference predicted position where the damage degree is “1” rather than the distance from the interference predicted position where the damage degree is “2” when the shaking of the building is detected by the sensor. The avoidance position is determined so that the distance is longer, and the car 2 is stopped at the determined avoidance position. Other configurations are the same as those in the first embodiment.

In such an elevator, the priority determined from the viewpoint of the damage level is set in the control device corresponding to each predicted position of interference, and the control device detects each interference when the shaking of the building is detected by the sensor. Since the avoidance position for stopping the car 2 is determined based on the priority order corresponding to the predicted position, it is possible to more reliably prevent the elevator from being damaged when the building is shaken.

In the above example, for example, the priority among the predicted interference positions corresponding to the damage level indicated by “1” and the priority order among the predicted interference positions corresponding to the damage level indicated by “2”. Is not set, but the priority order may be set finely among a plurality of predicted interference positions corresponding to the same damage level. Moreover, you may determine the priority of each interference estimated position from other viewpoints (for example, viewpoint of the probability of occurrence of interference, etc.) instead of the damage level.

In the above example, the configuration related to the priority order of each interference predicted position is applied to the first embodiment. However, the configuration related to the priority order of each interference predicted position may be applied to the second or third embodiment. .
