Description

  The present invention relates to an elevator renewal method.

  Since the elevator renewal work usually takes several days, the customer is required to shorten the elevator stop time as much as possible so as not to reduce the operation time. As a general construction method, a construction method is adopted in which the elevator is operated without renewal work during the daytime when there are many elevator passengers, and the work is performed at night when there are few elevator passengers. In that case, in order to operate the elevator in the daytime, an operation panel is temporarily placed in the car, and the elevator is operated using the temporary operation panel.

  For example, as an elevator repair method that can significantly reduce the continuous downtime, after performing the process of removing the existing car position indicator and the existing frame and the process of removing the existing operation panel and the existing side plate, the existing frame is replaced. After the process of attaching the repair frame to the upper side of the car door and the process of attaching the repair side board to the right sleeve wall of the car door instead of the existing side board, the temporary car position indicator and the existing operation panel After the first construction process consisting of the process of temporarily holding the repair side plate to the repair side plate, the normal operation process of the elevator is performed, and then the repair operation panel is attached to the repair side plate in place of the existing operation panel; There has been proposed a construction method for performing a second construction process including a process of attaching a repair operation panel to the repair side plate instead of the temporary car position indicator (see, for example, Patent Document 1).

  Further, in the elevator refurbishment method in which the first construction for replacing the existing elevator control device with the new elevator control device and the second construction for replacing the existing passenger car with the new elevator car are performed at different times, The first work is performed before the second work. In the first work, a new operation panel corresponding to the new elevator control device is attached to the side plate of the existing car via a mounting member. Then, there is a construction method in which a new operation panel is removed from an existing car and attached to a newly installed car (see, for example, Patent Document 2).

  Furthermore, in order to shorten the continuous stop period and reduce the trouble to the elevator user, the first period with a state enabling the operation of the elevator before and after the second period work performed by stopping the operation of the elevator. In addition to the work and the third stage work, the second stage work performed by stopping the operation of the elevator is divided into the machine room peripheral work and the car peripheral work, and these are performed in parallel. There has also been proposed a method for shortening the working time for continuous stoppage (see, for example, Patent Document 3).

  In such a conventional elevator renewal method, the new operation panel was installed at the same position where the existing operation panel was installed, but the removal and installation of the operation panel in the car is a particularly complicated and time-consuming operation. If it is difficult to replace the old and new operation panels in time, and it is necessary to operate the existing elevator in the middle of the renewal work, the old operation panel that was removed for the work needs to be temporarily re-installed in another position in the car was there.

  For this reason, the old operation panel is removed, the temporary operation panel is temporarily installed in the car, and the temporary operation panel is removed after the renewal work is completed, resulting in an increase in the construction period. In addition, elevator users need to operate with a temporary operation panel that they are not used to, and there is a problem in terms of convenience.

  Accordingly, an object of the present invention is to provide an elevator renewal method that eliminates the need to use a temporary operation panel in a car at the time of elevator renewal work and can perform renewal work in a short time while using an existing old operation panel. is there.

  The elevator renewal method according to the present invention is an elevator renewal method in which the old equipment of the existing elevator is replaced with new equipment and the elevator is renewed, and the old equipment remains at night and can be operated by the old equipment. The new equipment can be installed alongside the old equipment at least, including the operation panel in the cage, and the new equipment can be connected to each other with cables, and in the daytime There was a process to operate with equipment and a process to replace the old equipment with a new equipment that cannot be installed in the new equipment at night and to enable operation with the new equipment. It is characterized by.

  According to the elevator renewal construction method of the present invention, the construction period is shortened, and an effect is obtained that work can be performed without giving the user a sense of incongruity.

It is the schematic which shows the elevator which can apply the renewal construction method of this invention. FIG. 2 is a schematic front view of an elevator door device showing a state in which an existing operation panel and a new operation panel are provided side by side during renewal by the renewal method of the present invention. It is a general work time chart showing the renewal construction method of this invention.

  Embodiments of the present invention will be described below.

  FIG. 1 shows main equipment constituting an elevator apparatus system to which the renewal method of the present invention can be applied. In the elevator apparatus of FIG. 1, a machine room 1 is provided with a hoisting machine 2 including a hoisting motor, a control panel 3, and a speed governor 4. A hoistway 5 has a car 6, a counterweight 7, and a car. 6, a main rope 8 that connects the counterweight 7, a guide rail 9, and an end switch 10 are provided, and the car 6 is provided with a door driving device 11 including a door motor and an operation panel 12 in the car, An operation panel 14 is provided at the landing 13, and a shock absorber 16 is provided at the pit 15. The control panel 3 and the car 6 are connected by a moving cable 17, and a relay device 18 is provided for communication between the car 6 and devices such as the end point switch 10 on the hoistway 5 side.

  In the actual renewal method, the contents vary depending on the purpose of the renewal and customer requirements, and the construction period varies depending on the structure of the elevator, the number of units and the height of the building. Here, the elevator shown in Fig. 1 is used. A renewal method for switching the AC control method to the inverter control method in the apparatus will be described as an example. Further, the devices to be renewed are, for example, a hoisting motor and control panel 3 of the hoisting machine 2 in the machine room 1, an end point switch 10 of the hoistway 5, a door driving device 11 on the car 6, and the car 6 It is assumed that there are an operation panel 12 inside, an operation panel 14 at the hall 13, a moving cable 17 and a relay device 18 related to these devices. In such a case, the period of normal renewal work is about 2 to 3 days, but it is required to operate normally for transporting passengers during the daytime, so the work requires several night work for 8 hours. During the daytime, the operation is interrupted and normal operation is performed.

  In the renewal method according to the present invention in such a case, in the first work stage, the old equipment of the existing elevator is left as it is and can be operated, and at least in the car that can be additionally provided with the old equipment among the new equipment. This is the stage where new equipment that can be installed together with the operation panel is installed. After this work stage, the elevator can be operated normally in the daytime. The second work stage is a stage in which the old equipment of the elevator is removed and replaced with new equipment that cannot be installed in the old equipment, and the operation is switched to the new equipment. Later daytime normal operation of the elevator will be done by the new equipment. The third work stage is a stage in which the removed old equipment is removed, carried out, and each part is finished. Next, each work stage will be described in more detail.

First work stage: (Installing new equipment together)
As the first night work, new equipment that can be installed in the old equipment among the equipment that needs to be replaced (for example, the control panel 3, the end point switch 10, the moving cable 17, the relay device 18, the new operation) A panel 22 (see FIG. 2) is installed alongside the existing old equipment, and these new equipment are connected by a new cable. By this work, the installation work of the new equipment is partially completed, and the operation of the elevator with the old equipment can be continued. This operation can be performed sequentially using about 8 hours at night. At this time, the new equipment to be attached together is at least the new operation panel 22 in the car 6.

  FIG. 2 shows a state in which the car 6 is viewed from the inside, and the car 6 is provided with side plates 21 on both sides of the entrance 20 that is opened and closed by the door 19. An existing operation panel 12 which is an old device is provided. As part of the side-by-side installation of new equipment according to the present invention, the new operation panel 22 is attached to the side plate 21 on the side opposite to the entrance 20 while the old operation panel 12 attached to the side plate 21 of the car 6 is left as it is. Thus, the new operation panel 22 is attached to the side opposite to the old operation panel 12. Additional processing inside the car and cable wiring necessary for installation are completed at the same time, and the work of installing other new equipment performed during this work period is also completed. Since the operation panel 14 on the landing 13 side is easy to replace, such a side operation is not performed. In this state, since the old device is not touched, it can be operated by the old device.

  At this time, since the operation panel 12 which is the old device in the car 6 is in the original state, there is no problem including operability in daytime operation, and at the same time, the new operation panel 22 is attached. Since it is attached at a position different from the operation panel 12, it is not necessary to rush the work and complete the complicated work forcibly overnight, and it is possible to work at the operator's pace, which is a great merit. This work by the conventional construction method is time-consuming work because additional work and finishing work are required for the car 6 and work is performed in a limited work space in the car 6.

  As described above, since the elevator is in a state where it can be operated by the old equipment including at least the operation panel 12, normal operation during the daytime can be performed after the night working hours are completed. That is, for the passenger, the elevator can be used by using the operation panel 14 of the hall 13 and the operation panel 12 in the car 6 which are old devices in the same state as before the start of the renewal work. As in the past, temporary operation panels that are unfamiliar with the user are not forced to operate unfamiliar with the passengers, and passengers are not worried. For daytime operation, it is desirable to cover the new operation panel 22 attached to the side plate 21 with a cover.

Second work phase: (new and old switching work)
For the second night work, the old equipment (for example, the hoisting machine 2, the door drive device 11 and the landing operation panel 14) excluding the operation panel 12 among the old equipment left in the first night work is supported. Replaced with new equipment that cannot be installed (for example, new equipment corresponding to the hoisting machine 2, the door driving device 11, and the hall operating panel 14), and all equipment to be replaced are new equipment. In addition, the new equipment will be wired so that it can be operated with the new equipment. Since these operations are shared and can be performed independently, replacement of each device can be completed in one night (8 hours).

  Thus, since the elevator is in a state where it can be operated by the new equipment, normal operation during the daytime can be performed after the second night work is completed. That is, for the passenger, the elevator is in a state where the renewal work has been completed, and the elevator renewed using the operation panel 14 which is a new device of the hall 13 and the new operation panel 22 in the car 6 can be used. As in the past, temporary operation panels that are unfamiliar with the user are not forced to operate unfamiliar with the passengers, and passengers are not worried. For daytime operation, it is desirable to cover the new operation panel 22 attached to the side plate 21 with a cover.

Third work phase: (Removal of existing equipment)
By night work, all the old elevator equipment is removed from the elevator and carried out for finishing work. Finishing operations such as removal of existing equipment including the existing operation panel left so far and replacement of the side plate 21 from which the operation panel 12 which is the old equipment is removed are sequentially performed at night. A simple time chart for the above operation is shown in FIG.

  As described above, the elevator renewal construction method according to the present invention replaces the old equipment of the existing elevator with the new equipment and renews the elevator, so that the old equipment is left and operated by the old equipment at night. The process of attaching the new equipment that can be installed together including the operation panel in the cage that can be installed together with the old equipment among the new equipment, and connecting the new equipment that can be installed together with a cable, In the daytime, the process of providing passengers with the old equipment, and at night, the old equipment is replaced with a new equipment that cannot be attached to the old equipment among the new equipment. And a process for enabling driving.

  However, it is possible to repeat the process of attaching new equipment that can be installed together and connecting these new equipment with cables with each other, and the process of providing passengers with the old equipment during the day, depending on the progress of the renewal work, The new equipment that can be installed side by side may include a control panel, a hoistway end switch, a moving cable, and a relay device.

  In addition, the new operation panel in the car may be provided at a position different from the position where the operation panel, which is the old device, is provided. The new operation panel has a side plate and an entrance on which the operation panel is attached. You may make it attach to the side plate on the opposite side on both sides. Furthermore, a process of removing all the old equipment from the elevator may be provided after the process of enabling operation by the new equipment.

  The elevator apparatus illustrated and described above is merely an example, and various modifications can be made, and the features of each specific example can be used altogether or selectively combined. For example, for the purpose of explaining the invention, the renewal operation has been described as switching AC control to inverter control, but the present invention can also be applied to a renewal method for other purposes. Further, the range of devices to be renewed is not limited to the range described above.
