Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning a stepped surface of a passenger conveyor, and more particularly to a deep step inside a truss that falls when a step reverses from an upper part to a lower part in a machine room. The present invention relates to a step step surface cleaning device suitable for cleaning light dust such as cotton dust that may be scattered.

[Conventional technology]

As this kind of prior art, there is one disclosed in Japanese Patent Application Laid-Open No. 58-224979. In this prior art, a cleaning brush attached to a linear motor and driven reciprocally is arranged in a machine room of an escalator, and the stepping surface is cleaned by sliding the cleaning brush.

[Problems to be solved by the invention]

In the above-described conventional technology, among the dust adhered to the step step surface, dust having a weak adhesive force such as cotton dust that falls from the step surface when the step is inverted from the upper portion to the lower portion in the machine room is described. No consideration was given. Therefore, when the brush is slid when cleaning dust,
There is a risk that dust such as cotton dust may be scattered and deposited deep inside the truss. If dust such as cotton dust accumulates deep in such a truss, a lot of labor and time are required since many steps are required to be removed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stepping surface cleaning device for a passenger conveyor that can reliably collect dust without weakly adhering trash to the stepping surface without scattering into the truss.

[Means for solving the problem]

An object of the present invention is to provide an apparatus for cleaning a stepped surface of a passenger conveyor having a plurality of endlessly connected steps running between two entrances and exits, wherein a part in a machine room immediately below a position where the steps are inverted from an upper part to a lower part. A storage box for storing garbage is fixed, and the storage box is provided with a garbage storage opening that opens toward the step surface of the step of reversing from the upper part to the lower part, and is attached near the storage opening; A tip side is provided with a brush contacting the step surface of the step, and a fire prevention means capable of extinguishing ignited garbage is provided inside the storage box, and trash can be collected inside the storage box. This is achieved by providing a bag and providing the storage box with a collection port through which the bag can be taken out of the storage box.

[Action]

In the present invention configured as described above, the flow of air generated by the running of the step is guided toward the storage port of the storage box by the step surface of the step when reversing from the upper part to the lower part. Garbage such as cotton dust dropped from the step surface of the step naturally flows into a bag arranged inside the storage box and is collected without being scattered around.

In addition, the brush removes dust such as cotton dust adhering to the step surface of the step and regulates air generated by the step traveling from flowing between the step surface and the storage box in the step traveling direction. Thus, it is possible to prevent light dust such as cotton dust from being carried inside the truss by the air flow.

Further, when garbage such as a lit cigarette is collected in the bag of the storage box, the fire of the garbage can be extinguished by the fire prevention means.

Furthermore, the garbage collected in the bag arranged inside the storage box can be taken out from the collection port of the storage box.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. In FIG. 1, reference numeral 1 denotes a storage box for storing garbage. The storage box 1 has a storage port 2 which opens toward a step surface 7 of a step 6 at an upper portion, and forms a front edge side when the step 6 enters. The brush 3 is attached to the part 2A that does.
As shown in FIGS. 1 and 2, the storage opening 2 is formed in a tapered shape in which the height gradually decreases from the portion 2A forming the front edge side to the portion 2B forming the rear edge side.

The brush 3 described above can contact the step surface 7 of the step 6, and when the step 6 moves in the direction of the arrow in FIG. 2, the brush 3 relatively slides on the step surface 7 to remove dust. . The trash removed in this way falls from the storage port 2 into a bag arranged in the storage box 1. The garbage dropped in the bag is kept in the bag as it is, so that it does not scatter outside again. When the garbage has sufficiently accumulated in the bag, the bag may be taken out from the collection port 5 and discarded together with the bag in a predetermined place. Therefore, the work of collecting garbage is easy, and this work can be efficiently performed.

The storage box 1 described above is fixed inside the machine room immediately below the position where the step 6 of the escalator is inverted from the upper part to the lower part, as shown in FIG. It is formed in an L-shape.

In general, most of the garbage entering the truss 8 from outside the passenger conveyor is garbage on the step surface while the step 6 is traveling on the upper side (the side where passengers can get on and off). Are dropped when step 6 is reversed in the machine room. In addition, since the step 6 is traveling inside the truss 8, an air flow is generated, and light dust such as cotton dust among the trash dropped from the step surface of the step 6 floats in the truss 8 conventionally. The fact was that it was deposited deep inside. Further, since a chain or the like for running the step 6 is also provided in the truss 8, oil is dripped. If there is cotton dust, the oil accumulates in a washed state.
Therefore, if a lit cigarette or the like falls on the oiled dust, there is a risk of starting a fire.

In the present invention, even light dust such as cotton dust is brushed off by the brush 3 when the step 6 enters the machine room, and stored in the bag of the storage box 1, so that it is scattered to the outside again. Never. Therefore, dust does not accumulate in the truss 8. If a lit cigarette or the like falls into the bag of the storage box 1, the storage box 1
The fire can be extinguished by fire prevention means, for example, water, sand, pebbles, or the like, which is disposed at the bottom or the like, thereby preventing the occurrence of a fire.

In the present invention, since the side shape of the storage box 1 is formed in an L-shape corresponding to the traveling path of the step 6 as described above, the space between the lower part of the step 6 and the truss 8 is provided. The formed narrow space can be used as an arrangement space for the storage box 1. That is, if the length dimension of the storage box 1 along the traveling direction of the step 6 and the width dimension along the direction orthogonal to the traveling direction of the step 6 are set relatively large, the space between the lower part of the step 6 and the truss 8 is set. Despite being narrow, a sufficient dust storage volume can be secured.

〔The invention's effect〕

According to the present invention, garbage such as cotton dust having low adhesiveness carried by the step surface of the step naturally flows into the bag of the storage box and is collected without being scattered around. In addition, since dust attached to the step surface of the step is brushed off and stored in the bag of the storage box, the dust is not transported to the truss while being attached to the step. Therefore, dust does not accumulate in the deep part of the truss unlike the related art, and the cleaning does not require much labor and time.

Further, when lit garbage is collected in the bag of the storage box, the fire can be extinguished by the fire prevention means provided in the storage box, and the occurrence of a fire can be prevented.

Further, the bag in which the garbage is collected can be taken out from the collection port of the storage box, and the garbage can be discarded efficiently.
