Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator renewal method for sequentially replacing a plurality of elevators installed in a predetermined number with new elevators.

[0002]

2. Description of the Related Art A conventional elevator renewal method of this type will be described with reference to an example in which three hall elevators can be operated by one hall button. Conventionally, for example, two methods are implemented.

The first conventional renewal method is as follows. (1-1) The predetermined number of units to be removed and replaced is preset to one. (1-2) Remove the first existing elevator and replace it with the corresponding new elevator. During this period, the remaining two existing elevators will continue to operate using the existing hall buttons. In addition, a temporary hall button will be installed in the curing box installed on the floor of the elevator hall for the operation of the new elevator. Therefore, in this state, one new elevator can be operated by the temporary hall button,
The existing hall button allows the operation of two existing elevators.

(1-3) Next, the second existing elevator is removed and replaced with a corresponding second new elevator. As a result, the remaining existing elevator becomes one,
There will be two new elevators. Also, with the existing hall button, 1
The existing elevators of the rest of the cars can be operated, and the temporary hall buttons can be used to operate the two new elevators.

(1-4) Next, the third existing elevator is removed and replaced with a corresponding third newly installed elevator. As a result, all existing elevators will be removed and all three will be new elevators. All of these new elevators can be operated with temporary hall buttons.

(1-5) Finally, the existing hall button is removed, and the temporary hall button of the curing box is moved to the position where the existing hall button was as a new hall button. At this time, connection work is performed between the temporary hall button and the existing control panel that controls the operation of the new elevator. In this way, the replacement work of the three existing elevators with the new elevators, that is, the renewal is completed. It should be noted that all of the three new elevators become inoperable during the above-mentioned transfer of the temporary hall buttons and connection work of the existing control panel.

The second conventional renewal method is as follows. (2-1) The predetermined number of units to be removed and replaced is preset to one. (2-2) Remove the first existing elevator and replace it with the corresponding new elevator. During this period, the remaining two existing elevators are kept operable by the existing hall buttons.

(2-3) The existing hall button is removed and a new hall button is installed at that position. At this time, connection work is performed between the new hall button and the existing control panel that controls the operation of the new elevator. During installation of this new hall button and connection work with the existing control panel, one new elevator and two
All the remaining existing elevators on the car are out of service. After the work is completed, one new elevator can be operated with the new hall button.

(2-4) Next, the second existing elevator is removed and replaced with a corresponding second newly installed elevator, and this second newly installed elevator is also operated by the above-mentioned new hall button. Make it possible.

(2-5) Finally, the third existing elevator is also removed and replaced with a corresponding third newly installed elevator, and this third newly installed elevator can also be operated by the new hall button. To do so. This completes the renewal of the three existing elevators to the new elevator.

[0011]

In the above-mentioned first conventional renewal method, as described in the above procedure (1-5), the temporary hole button of the curing box is moved as a new hole button, and this is moved. When connecting the temporary hall button and the existing control panel that controls the operation of the new elevator, all three new elevators are in a non-operational state. In particular, the connection work between the relocated temporary hall button and the existing control panel generally takes a long time, so that the operation of all the new elevators will be stopped over a long time.

Similarly, in the above-mentioned second conventional renewal method, as described in the above procedure (2-3), the existing hole button is removed, a new hole button is installed at that position, and this new hole button is installed. When the button is connected to the existing control panel that controls the operation of the new elevator, all the elevators including the existing elevator and the new elevator will be inoperable for a long time.

That is, in both the conventional first and second renewal methods, there is a time during which all elevators cannot be operated, and the time during which they cannot operate becomes relatively long.

Therefore, these conventional techniques have a problem that inconvenience is caused to elevator users and serviceability is deteriorated. In addition, for example, to perform work that makes all elevators inoperable on holidays of the building in which the elevator is installed, set the overall work schedule and work schedule, etc. for renewal work schedules and work schedules. There is a problem of being constrained.

In the first conventional renewal method,
When connecting the temporary hall button to the existing control panel via the existing signal line, or when removing the existing hall button and relocating the temporary hall button, accidentally disconnect the existing signal line connected to the existing control panel. Or there is a concern that wiring may be mistaken.
Also, in the second conventional renewal method, when the existing hall button is removed and the new hall button is connected to the existing control panel via the existing signal line, the existing signal line that is accidentally connected to the existing control panel is disconnected. There is a concern that it may be cut or the wiring may be mistaken. In this way, if the existing signal line is erroneously cut or erroneously wired, operation of all elevators will be disabled. Therefore, it is necessary to perform processing work for prompt recovery.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and an object thereof is to replace an existing elevator with a new elevator without causing a time in which all the elevators are inoperable at the same time. It is to provide a renewal method of an elevator capable of performing.

[0017]

In order to achieve the above object, a plurality of inventions according to claim 1 of the present invention are installed,
An existing elevator that can be operated by operating a specific existing hall button provided in the elevator hall is preset to be removed in multiple times for each predetermined number of units, and in sequence,
In the renewal method of an elevator to be replaced with a new elevator, the remaining existing elevators can be operated by operating the existing hall buttons while installing the specified number of new elevators corresponding to the removal of the specified number of existing elevators. The new hall button related to the new elevator is provided at a predetermined operable position in the elevator hall, the operation of the newly installed elevator is enabled by operating the new hall button, and the remaining existing During the installation of the new elevator corresponding to the removal of the elevator, keep the operation of the new elevator installed by operating the new hall button, to remove all existing elevators, and to remove the existing hall buttons Even after installation of all new elevators, all of the above new It is to keep to enable the operation of the elevator.

In the invention according to claim 1 of the present invention thus configured, when a plurality of existing elevators are renewed, the work of replacing a predetermined number of existing elevators with a corresponding predetermined number of new elevators During the period, the remaining existing elevators can be operated by the existing hall button, and the customer can use the remaining existing elevators.
