Generally, in the renovation work of the elevator, it is necessary to make the operation period of the elevator as short as possible so as not to disturb the normal activities in the building. Even during the working period, hospitals, hotels, etc. are required to operate elevators when necessary. In addition, it is desirable to avoid the use of fire for disaster prevention, as well as new parts to be replaced due to repair work,
At the time of this construction, we will use standard products manufactured at the factory to reduce prices and shorten the manufacturing period, and avoid the use of special tools and work requiring special skills at the repair site. It is desirable to be able to easily perform the work.

However, as described above, in the conventional elevator remodeling method, the existing installation electric wire is replaced with the new installation electric wire 20.
Until the exchange of the signaling device 50 on each floor is completed after the replacement, the connection work of about 20 wires per floor must be performed so that the newly installed installation electric wire 20 and the connecting electric wire 30 are connected by the terminal 60. In addition, the elevator operation must be stopped during this work period, and the elevator continuous stop time becomes long.

It is an object of the present invention to provide an elevator remodeling method capable of performing normal operation during work and shortening the continuous stop time of the elevator.

[0008]

In order to achieve the above object, the present invention provides a hoistway between an existing signal device provided in a storage box at a hall and an existing control device provided in a machine room. In an elevator remodeling method in which the existing signaling device is connected by an existing installation signal and at least the existing signaling device is replaced with a new signaling device, the existing installation cable connected to the existing signaling device is disconnected in the storage box. Then, add a connection wire having a first connector connectable to the new signal device and reconnect this disconnection part, then cut the existing installed electric wire and remove the existing signal device to the new signal device. It is characterized in that the attached second connector is connected to the first connector.

[0009]

According to the elevator remodeling method of the present invention, the existing installed electric wire is cut in the storage box as described above, and the connecting wire having the first connector connectable to the new signal device is added to the cut portion. Since the connection is made again, at the end of this work, the normal operation of the elevator can be performed using the existing signaling device. After that, by cutting the existing installed electric wire at an appropriate time, removing the existing signal device, and connecting the second connector attached to the new signal device to the first connector, the normal operation of the elevator using the new signal device is performed. You can drive. Therefore, the normal operation can be performed during the work so that the continuous stop time of the elevator can be shortened.
