Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator wiring replacement method for replacing wiring connecting elevator equipment provided on each floor of a building and its control unit with new wiring.

[Background of the invention]

Conventionally, when replacing wiring in order to repair aging elevator equipment or modify it to improve performance, the work method used was to simultaneously remove all the wiring in the area to be replaced and install new wiring. This will be explained using a diagram.

@3 Figures (a) and e (b) are a front view and a side sectional view of an elevator in a building. In the diagram, 1 is the elevator landing on each floor of the building, 2 is the elevator entrance/exit frame, 3 is the elevator door, 4 is the floor indicator that displays the current position of the elevator corner, and 5 is the elevator on the relevant floor. It is a call switch that calls. Reference numeral 6 indicates a hoistway through which elevators go up and down, 7 indicates a machine room floor on the top floor, and 8 indicates a control panel for exchanging signals with floor indicators 4, call switches, etc., and executing predetermined controls. 9 is a main wiring connected to the control panel 8 and arranged in the hoistway 6 through each floor; 10 is a branch box provided on each floor via the main wiring 9; and 11a is a main wiring connected to the branch box 10. 9 and the floor indicator 4, llb is connected to the main wiring 9 by the branch box 10.
This is a branch wiring that connects the switch 5. In addition,
In M3 diagrams [a) and (b), only one floor is labeled with each symbol, but the same applies to other floors, so the description of the symbols for those other floors will be omitted.

In this difficult elevator, when the main wiring 936 and the branch wiring 11a, llb were to be replaced for the above purpose, these wirings were removed at the same time, and then new wiring was installed at the same time. For this reason.

It takes a long time (for example, 10
During this period, the elevator operation has to be stopped.If the building has only one elevator, people and cargo must be moved up and down the stairs. This has the drawback of causing a great deal of inconvenience. Furthermore, even if the building is equipped with multiple elevators, if one or more of them stops operating due to the above-mentioned wiring replacement, it may cause a great deal of inconvenience and inconvenience to the users, although the degree may vary. There is no difference in applying .

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator wiring replacement method that eliminates the drawbacks of the above-mentioned prior art and avoids the suspension of elevator operation during normal operation.

[Summary of the invention]

In order to achieve the above object, the present invention provides an existing main wiring 9
Install new main wiring in parallel to the branch line, connect this new main wiring to the existing branch line, disconnect the existing main wiring in the control section, connect the new main wiring, and connect the existing main wiring to the existing branch line. It is characterized by removing the main wiring and branch line and wiring a new branch line.

[Embodiments of the invention]

Hereinafter, the present invention will be explained based on illustrated embodiments.

FIGS. 1(a) and 1(b) are a front view and a side sectional view of an elevator in a building, showing a wiring replacement method according to an embodiment of the present invention. In the figure, parts that are the same as those shown in FIGS. 3(a) and 3(b) are given the same sign. Reference numeral 12 denotes a new main wiring arranged along the existing main wiring 9, and the upper end of this main wiring 12 is an open end. 13 is an existing branch box 10 located halfway through the new main wiring 12.
It is a branch box provided near 0, and has a connection part corresponding to the connection part of the 1 branch box 10. A branch line 14 connects the branch box 10 and the branch box 13.

The details of these wirings will be further explained using FIG. 2.

FIG. 2 is a wiring diagram of a part of the wiring shown in FIG. 1. In the figure, the same parts as those shown in FIG. 1 are given the same reference numerals. 4a is an indicator lamp provided in the floor indicator 4;
b is a terminal provided within the floor indicator 4. Reference numeral 8a indicates a terminal block provided in the control section 8, and reference numeral 8b indicates each terminal on the terminal block 8a.

Reference numeral 10a denotes a connection section placed in the existing branch box 10. 12a indicates the open end of the new main wiring 12, and
13a indicates a connecting portion of the branch box 13. Each connection part 1
3a corresponds to each connection portion 10a of the existing branch box 10. Branch line 14 connects corresponding connections 510m and 13m. In Figure 2, the existing part is drawn with a solid line, and the new part is drawn with a broken line. The control unit 8 detects which floor the elevator car is currently on, and lights up the indicator lamp 4a corresponding to the floor from the corresponding terminal 8b, via the connection unit 10a, and the terminal 4b.

Here, a method of replacing the existing main wiring 9 and branch line 11a with new ones will be explained. First, new main wiring 1
2. Arrange the branch box 13 and branch line 14. At this time, the upper end of the main wiring 12 is an open end. Next K
, connection of branch box 10! ! 10a and branch box 1
A branch line 14 connects the corresponding connection part 13a of No.3.
Connect with.

As a result of this connection using the branch line 14, the new main wiring 12 and the existing branch line 11a are connected. Note that the open end 12a of the main wiring 12 should be covered with an insulating material, etc.
It goes without saying that each wire should not come into contact with each other or with other equipment. Since the above-mentioned work can be performed only partially, it can be performed at night or on holidays, when the elevator is not operating.

Next, the main wiring 9 is removed from each terminal 8b of the control unit 8, and the open end 12a of the new main wiring 12 is connected to the corresponding terminal 8b. Then, the open end of the removed main wire 9 is insulated so that the wires of the main wire 9 do not come into contact with each other. This creates a new main wiring 129 branch branch box 139 line 14. The floor indicator 4 is activated via the existing branch box 10 and the existing branch line 11a. The connection between the main wiring 9 and the main wiring 12 can be changed in a short time.

Next, the existing main wiring 9 is removed, and the existing branch line 1 is removed.
Replace 1a with a new branch line. These tasks can be carried out in parts and are carried out at night or on holidays.

Incidentally, the wiring of the call switch 5 should also be replaced by the same method.

In this way, in this embodiment, a new main wiring and branch box are installed in parallel to the existing main wiring and branch box, these two branch boxes are connected by a branch line, and the main wiring is connected in the control section. We changed the existing main wiring to the new main wiring, then removed the existing main wiring and branch lines and wired the new branch lines, so we were able to partially replace the wiring. 2) Work can be done at night and on holidays, and in the end, elevator outages can be avoided during normal times.

Incidentally, if each terminal, each connecting part, and each open end of each wiring are configured so that connection can be made by inserting the plug, the replacement work can be carried out extremely quickly.

〔Effect of the invention〕

As described above, in the present invention, a new main wiring with one end open is installed parallel to the existing main wiring, this new main wiring is connected to the existing branch line, and the connection in the control section is made to the existing main wiring. In addition to changing the wiring to new main wiring, we also removed the existing main wiring and branch lines and installed new branch lines, making it possible to partially replace the wiring, and this work could be done at night or on holidays. By doing so, it is possible to avoid elevator outages during normal times.
