The cable 11 is connected to the control device 7. The cable 11 includes, for example, a cable for control and a cable for power supply.

  FIG. 1 shows an example in which the hoisting machine 6 and the control device 7 are installed in the machine room 5, but this is an example. The hoist 6 and the control device 7 may be installed in the hoistway 3. When the hoisting machine 6 is installed in the hoistway 3, the hoisting machine 6 may be installed at the top of the hoistway 3 or may be installed in a pit of the hoistway 3.

  FIG. 2 is a perspective view showing an example of the car 1. As shown in FIGS. 1 and 2, the car 1 includes, for example, a main body 20, a door 21, a motor 22, an operation panel 23, a driving device 24, and a clasp 25.

  The main body 20 forms a cab for passengers to get on. The main body 20 includes members for forming a cab, such as a floor, walls, and a ceiling. The main body 20 may include a frame supporting a member such as a floor. The door 21 is supported by the main body 20. The door 21 opens and closes an entrance formed in the main body 20. The electric motor 22 generates a driving force for driving the door 21. The car 1 is provided with a mechanism (not shown) for converting the rotation operation of the output shaft of the electric motor 22 into the opening / closing operation of the door 21.

  The operation panel 23 is provided inside the main body 20. The operation panel 23 is a device for the passenger inside the main body 20, that is, the passenger in the cab to input information. Information from the operation panel 23 is input to the control device 7 via the operation device 24 and the cable 11.

  The driving device 24 is provided on the main body 20. The driving device 24 controls the electric motor 22. That is, the opening and closing of the door 21 is controlled by the driving device 24. The cable 11 extending from the control device 7 is connected to the operation device 24. For example, an electric wire forming a part of the cable 11 is connected to the operating device 24 via the connector 11a. The electric wire forming another part of the cable 11 is connected to the operating device 24 via the connector 11b. The electric wire forming another part of the cable 11 is connected to the operating device 24 via the connector 11c. The cable 11 is connected to the operating device 24 by a plurality of connectors.

  The operating device 24 is provided detachably with respect to the main body 20. For example, the driving device 24 is attached to the main body 20 by a clasp 25 such as a patch lock which can be operated manually without using a tool.

  In normal operation of the elevator, the car 1 stops at the height of the landing 12 provided in the building. The normal operation is an operation for causing the car 1 to sequentially respond to the registered call. When the car 1 is placed at the height of the landing 12, the door 21 of the car 1 faces the door 13 of the landing 12. When the car 1 is placed at the height of the landing 12, the door 13 of the landing 12 interlocks with the movement of the door 21. That is, when the door 21 opens, the door 13 opens. When the door 21 closes, the door 13 closes.

  The range in which the door 13 interlocks with the movement of the door 21 is called a door zone. That is, the door zone is a range in which the door 21 of the car 1 can be opened. When the car 1 stops at the door zone of the hall 12, the door 13 of the hall 12 is linked with the movement of the door 21.

  FIG. 1 shows an example in which landings 12a to 12c are provided in a building as the landing 12 where the car 1 stops. A hall other than the halls 12a to 12c may be provided in the building. The landing 12b is a landing provided on a floor one level higher than the floor on which the landing 12a is provided. The landing 12c is a landing provided on a floor one level higher than the floor on which the landing 12b is provided. The landing 13a is provided with a door 13a. The landing 13b is provided with a door 13b. The hall 13c is provided with a door 13c.

  FIG. 1 shows a state in which the car 1 has stopped between the landing 12a and the landing 12b due to a power failure or the like. FIG. 1 shows an example in which a passenger is trapped in the car 1 in a state where the car 1 and the counterweight 2 are in equilibrium. Hereinafter, a method for rescuing the passengers in the car 1 under such a situation will be described.

  FIG. 3 is a flowchart illustrating a passenger rescue method according to the first embodiment. For example, when a passenger is trapped in the car 1 (S101), a maintenance company is dispatched from the management company that manages the elevator device to rescue the passenger. When confinement occurs due to a power failure or the like, the car 1 cannot be moved by the electric motor 9. Therefore, the maintenance person attempts to move the car 1 using the difference between the weight of the car 1 and the weight of the counterweight 2.

  Specifically, the maintenance staff shuts off the power of the elevator in order to prevent unexpected operation restart due to restoration of the power failure. Next, the maintenance person manually releases the brake device 10 of the hoisting machine 6 by using a specific tool. As a result, the drive sheave 8 becomes rotatable. If the car 1 is lighter than the counterweight 2 when the passenger is trapped in the car 1, the car 1 moves upward by releasing the brake device 10. If the car 1 is heavier than the counterweight 2 when the passenger is trapped in the car 1, the car 1 moves downward by releasing the brake device 10.

  On the other hand, when the passenger is trapped in the car 1 in a state where the car 1 and the counterweight 2 are in equilibrium, the car 1 does not move even if the brake device 10 is released. If the car 1 does not move even when the brake device 10 is released, the maintenance person confirms that the car 1 and the counterweight 2 are in an equilibrium state (S102).

  In such a case, the maintenance worker operates the brake device 10 and then moves to the landing 12b. Then, the maintenance person opens the door 13b of the hall 12b and moves on the car 1 from the hall 12b (S103). When the maintenance person moves on the car 1, the maintenance person removes the operating device 24 from the main body 20 (S104).

  In S104, the maintenance person disconnects the cable 11 connected to the operation device 24 from the operation device 24 by disconnecting the connector from the operation device 24. The maintenance person fixes the cable 11 detached from the operating device 24 to the main body 20. When fixing the cable 11 to the main body 20, an adhesive tape or the like may be used. Next, the maintenance person releases the operating device 24 from the main body 20 by releasing the clasp 25.

  When removing the operating device 24 from the main body 20, the maintenance person carries the removed operating device 24 to the landing 12b (S105). When the operator places the operating device 24 on the landing 12b, the maintenance staff closes the door 13b of the landing 12b and moves to the machine room 5.

  Next, the maintenance person manually releases the brake device 10 by using a specific tool (S106). In S106, the driving device 24 has been removed from the car 1. Therefore, when the brake device 10 is released, the car 1 moves upward. The maintenance person performs the releasing operation of the brake device 10 while checking the height of the car 1 to stop the car 1 in the door zone of the landing 12 (S107). For example, the maintenance person stops the car 1 in the door zone of the landing 12b.

  After stopping the car 1 in the door zone of the landing 12b, the maintenance worker moves to the landing 12b. Then, the maintenance person opens the door 13b and the door 21 from the landing 12b (S108). Thereby, the passenger in the car 1 can go out of the car 1 to the hall 12b.

  In the example shown in the present embodiment, the car 1 is made lighter than the counterweight 2 by removing the driving device 24 from the main body 20. Since the removed driving device 24 is carried to the landing 12, it is not necessary to change the rescue weight many times to move the car 1 as in the related art. When the driving device 24 is removed from the main body 20, the car 1 can be moved to the door zone by releasing the brake device 10. Therefore, according to the example shown in the present embodiment, it is possible to rescue the passengers trapped in the car 1 in a short time. In addition, the burden on maintenance personnel can be reduced.

  Further, in the example shown in the present embodiment, it is not necessary to provide a weight necessary only to rescue the passenger. For this reason, it is possible to prevent the car 1 from becoming unnecessarily heavy.

  FIG. 4 is a flowchart illustrating an example of a work procedure after rescuing a passenger. When the passenger trapped in the car 1 is rescued in S108, the maintenance person closes the door 13b and the door 21 and then moves to the machine room 5 (S201). Next, the maintenance person manually releases the brake device 10 by using a specific tool (S202). In S202, no one is on the car 1. Therefore, when the brake device 10 is released, the car 1 moves upward. The maintenance worker performs the releasing operation of the brake device 10 while checking the height of the car 1, and stops the car 1 at a specific height so that the car 1 can be moved onto the car 1 from the landing 12 (S203). . For example, in S203, the maintenance person stops the car 1 so that the car 1 can be moved onto the car 1 from the landing 12c.

  After stopping the car 1 in S203, the maintenance worker moves to the landing 12c. Then, the maintenance person opens the door 13c of the hall 12c, and moves from the hall 12c to the car 1 (S204). At this time, the maintenance person carries the operating device 24 removed from the main body 20 in S104 onto the car 1.

  Next, the maintenance person attaches the operating device 24 to the main body 20 (S205). In S205, the maintenance person fixes the operating device 24 to the main body 20 using the clasp 25. The maintenance person connects the cable 11 removed in S104 to the operating device 24. When the maintenance person attaches the driving device 24 to the main body 20, the maintenance person moves to the landing 12c.

  In order to prevent a connection error from occurring when the cable 11 is connected to the driving device 24 in S104, a code or the like indicating a pair is printed on a connector provided on the cable 11 and a socket for receiving the connector. May be. When the cable 11 is connected to the operating device 24 by a plurality of connectors, each of the plurality of connectors may have a different shape. As another example, the entire cable 11 may be connected to the operating device 24 by one connector.

  In the example shown in FIG. 4, the car 1 is moved upward after rescuing the passenger. For this reason, if a passenger is rescued at the landing 12 on the top floor, the maintenance person cannot get on the car 1 thereafter. In consideration of rescuing passengers at the landing 12 on the top floor, the counterweight 2 may be configured to be vertically divided.

  In this case, when the maintenance person rescues the passenger at the landing 12 on the top floor, the maintenance person moves to the pit of the hoistway 3. Then, in the pit, the lower part of the counterweight 2 is cut off from the upper part, and the counterweight 2 is made lighter than the car 1. If the brake device 10 is released in this state, the car 1 can be arranged at a height at which the car 1 can be moved from the landing 12 on the top floor onto the car 1. The maintenance staff can get on the car 1 again from the landing 12 on the top floor and attach the driving device 24 to the main body 20.

  The present invention can be used to rescue a passenger trapped in a car.
