DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step cleaning method for a passenger conveyor such as an escalator and an automatic line.

[0002]

2. Description of the Related Art Generally, a passenger conveyor is provided with a plurality of steps which are connected endlessly, and a passenger enters the vehicle while the plurality of steps move. In such a passenger conveyor, the steps are soiled by dust or the like adhering to the shoes or the like of the passengers, so that the steps need to be periodically cleaned.

[0003] Conventionally, on the steps of a passenger conveyor that has been used for a long period of time, dust attached to the steps does not easily fall off.

[0004]

However, in the above-mentioned prior art, since all steps are sequentially washed in order to wash, there is a problem that the maintenance staff involved in the work takes too much labor. In particular, for passenger conveyors such as escalators installed in department stores, if the steps are dirty, the appearance is poor, and customers such as department stores may be required to frequently wash the steps. Because of the large number, the above-mentioned problem that the maintenance staff takes too much labor was remarkable.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation in the prior art, and has as its object to provide a method of cleaning a passenger conveyor in which a plurality of steps can be efficiently cleaned and a good-looking step can be obtained. Is to provide.

[0006]

To achieve the above object, the present invention relates to a method of cleaning a plurality of steps provided on a passenger conveyor, the method comprising the steps of:
Removing the plurality of steps from a step rail, attaching a curing member for water-tightly curing the front wheels of the removed steps, arranging the steps on a floor, and arranging the steps on the floor. A step of injecting pressurized water toward the steps, a step of removing dirt on the steps with a brush after the end of the injection step, and a step of blowing compressed air toward the steps after the end of the cleaning step, After completion of the spraying step, a step of repairing a portion of the step where the paint has peeled off, and after completion of the repairing step, a step of applying a stain preventing agent to the step, and after completion of the applying step, The method includes a step of removing the curing member from the step and a step of attaching the step to the step rail after the completion of the curing removing step.

In the present invention having the above-described structure, a plurality of steps are arranged side by side, and simultaneously pressurized water is jetted to remove dirt.
Since the drying is performed by blowing the pressurized air onto the steps, the time required for this spraying and drying operation can be reduced,
Thereby, a plurality of steps can be efficiently cleaned. In addition, the dirt on the steps that did not fall off with the injection of the pressure water was removed with a brush, and repairs were performed, such as applying paint again to the part where the paint on the steps was peeled off. it can. Furthermore, after removing the dirt from the steps, by applying a stain preventive agent to the steps, the degree of advance of the dirt on the steps can be suppressed, and from this point, the steps can be provided with good appearance.
