DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting maintenance device for an escalator, which can easily maintain a lighting provided at a bottom of the escalator.

[0002]

2. Description of the Related Art Generally, when a plurality of escalators are installed in parallel with each other so as to form the same projection plane in the vertical direction so as to face each other, an illumination for illuminating a lower part is provided at the bottom of an upper escalator. I have.

In addition, since it is necessary to periodically clean and replace the above-mentioned lighting, for example, a fluorescent lamp, conventionally, a stepladder is provided on a step of a lower escalator, and the exterior plate can be hung downward. In the meantime, a method of performing the maintenance work has been proposed.

[0004] Examples of this kind of maintenance work method are disclosed in JP-A-8-143260 and JP-A-8-26642.

[0005]

However, each of the above-mentioned prior arts has a disadvantage that the structure is large and it is difficult to implement it in terms of cost.

That is, when the distance between the upper and lower escalators, that is, when the floor height of the building where the escalator is installed is large, for example, when it is about 6 to 8 m, the stepladder does not have a considerably long dimension. In addition, a large-scale configuration for supporting the lower end portion of the step on the step was required, so that the stepladder was very expensive.

[0007] Further, even if the exterior panel on which the lighting is installed is hung downward and the maintenance work of the illumination is performed on the lower floor, similarly, the entire exterior panel is displaced, resulting in a large-scale configuration, which leads to cost reduction. It will be high.

The present invention has been made in view of such inconveniences, and has as its object to provide an escalator lighting maintenance device having a simple and inexpensive configuration and capable of easily performing maintenance work. It is in.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method in which a plurality of escalators are installed in parallel so as to form the same projection plane in the vertical direction. In the maintenance apparatus for escalator lighting provided with lighting for illuminating the escalator, a truss which is a strength member located at the bottom of the escalator is provided with a suspending means capable of suspending a ladder.

According to the present invention, the truss located at the bottom of the escalator is provided with a suspending means capable of suspending a ladder to constitute an escalator lighting maintenance device.
The maintenance work of the lighting can be easily achieved by climbing a ladder suspended by the suspending means.

[0011] Furthermore, since the structure is simple with only the suspension means, it can be inexpensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An escalator lighting maintenance apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view of an escalator in a state where a work ladder is installed using an escalator lighting maintenance device according to one embodiment of the present invention, and FIG. 2 is a detailed view of a portion A in FIG.

First, the structure of an escalator to which the maintenance device according to the present invention is applied will be described with reference to FIG.

As shown in FIG. 1, escalators 1a and 1
b are installed so as to face each other in parallel in the vertical direction so as to form the same projection plane. These escalators 1a and 1b are trusses 3a and 3b, which are strength members of the escalator supported by the building receiving beams 2a and 2b, respectively, and endless steps 4a and 4b that are supported by the trusses 3a and 3b and run. Handrails 5a, 5b running in synchronization with the steps 4a, 4b, exterior plates 6a, 6b attached to the trusses 3a, 3b so as to cover the bottoms thereof, and attached to the exterior plates 6a, 6b to illuminate the lower side. It has fluorescent lamps 7a and 7b as illumination.

Next, an escalator lighting maintenance apparatus according to the present invention will be described with reference to FIGS.

As shown in the drawing, the maintenance device of the present invention includes an inspection port 8 which enables the exterior plate 6a to rotate in the downward direction of the arrow, and a ladder 10 provided on the truss 3a at a position opposed to the inspection port 8. And a suspending hook 9 which is a suspending means capable of suspending.

The inspection opening 8 has a hinge 81 at one end.
And the other end face is pushed up from below, so that
An engagement portion (not shown) is provided to disengage the engagement with a and drop the inspection door 82 downward.

Therefore, according to the maintenance device of the present invention, at the time of the maintenance work of the lighting 7a, first, the inspection opening engaging portion is pressed from the lower escalator step 4a by using a long bar (not shown) or the like to perform the inspection. The mouth 8 is formed.

Next, the upper end of the ladder 10 is supported by the hanging hook 9, and in this state, the ladder 10 is climbed to perform cleaning and replacement as maintenance work of the lighting 7a.

If the maintenance work is completed, ladder 1
0 is removed from the hanging hook 9, and the inspection door 82 is closed in the reverse procedure to that described above. If this operation has been performed for all the lights 7a sequentially using the plurality of hanging hooks 9 and the inspection ports 8, the maintenance operation is completed.

As described above, according to the maintenance device of the present invention, the lighting device 7a has a simple and inexpensive structure in which only the inspection port 8 is provided on the exterior plate 6a, and the hanging hooks 9 serving as hanging means are provided on the truss 3a.
Maintenance work can be performed.

[0023]

According to the present invention, since the maintenance device for the escalator lighting is constructed as described above, it is possible to perform the maintenance work of the lighting with a simple and inexpensive structure.
