Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tread device for transporting passengers on a passenger conveyor such as a moving sidewalk or an escalator.

[0002]

2. Description of the Related Art FIG. 11 is a vertical sectional side view showing a schematic structure of a conventional escalator, and FIG. 12 is a partially enlarged view of the escalator. A front wheel 3 and a rear wheel 4 rolling on the rail 2 are provided, and are further connected to a step chain 5 wound endlessly along the guide rail 2.

[0003] Each of the step board devices 1 is driven by the step chain 5 and travels while being guided by the guide rail 2.

Incidentally, in such an escalator, the step chain device 5, the guide rail 2, and the step plate device 5 are connected to each other so as to smoothly move the step plate device 1 and to prevent the step chain 5 from being damaged. 1
The lubricating oil is normally supplied by hand or automatically by an automatic lubricating device between the front wheel 3 and the rear wheel 4.

Therefore, during operation of the escalator, this oil supply propagates from the step chain 5 to the surface of the step board frame 7 via the front wheel shaft 6 engaged with the step chain 5, and the oil is deposited on the surface side of the step board 8. It tends to smear and leach the surface. In particular, in such an escalator, the propagation path of the oil such as the step chain 5 or the like comes to the upper side of the tread plate device 1 because the return side of the tread plate is inverted and upside down, and the surface of the tread frame 7 is freely dropped. Leaching to the side and the contamination proceeds in a relatively short time.

[0006] When oil adheres to the surface of the tread 8 in this manner, dust carried by the passenger during transportation of the passenger and dust in the installation environment adhere to the surface so as to accumulate thereon. In addition, the contamination of the oil proceeds from the left and right sides of the tread 8 and is greatly affected by the step chains 5 and the guide rails 2 provided on the left and right. Further, these contaminations are used in terminals such as stations. In transportation and the like, the operation time and the high-load use time period are maintained, and the amount of lubrication to the mechanism having mechanical friction increases accordingly. As a result, the amount of lubrication propagation increases in proportion.

Therefore, under such an environment, a large amount of dust is carried, and contamination of the tread portion of the tread proceeds in a short time. This contamination occurs not only on the tread surface but also on the riser 9 which covers the step surface between the tread devices.

Further, the tread plate 8 and the back side of the riser 9 inside the tread device 1 (back side), the tread frame 7 and the like are
The upstream side of the oil propagation path, the amount of oil is large, and the amount of accumulated dust is large because dust cannot be usually cleaned, and the contaminant adheres to the inside so as to contain oil.

Therefore, no matter how much the surface side of the treadle device 1 is cleaned, oil containing contaminants leach from the inside one after another to the surface side, and the contamination proceeds.

When the tread (cleat) 8 and the riser 9 of the conventional treading device are incorporated in the escalator body, the cleat 8 is fastened to the tread frame 7 from the inside, and the riser 9 engages with the cleat 8. At the same time, it is fastened to the tread frame 7 where the fastening portion is not visible, and it cannot be disassembled without removing the tread device as a single unit from the escalator body.

[0011]

SUMMARY OF THE INVENTION
Cleaning at the installation site of the escalator can only be performed very lightly on the tread surface side, and the interior side is also limited to what can be performed on site.

For full-scale cleaning, each treading device is removed from the escalator main body at the installation site, and they are brought to the cleaning place by the transporting means. After cleaning the front and back, they are transported to the installation place again and reassembled. There is a need.
Therefore, these operations require time and money, and the escalator must be suspended during that time, and there is a problem that it is usually difficult to perform full-scale cleaning.

In addition, the contamination of the treads with oil proceeds within a relatively short period of time, and it is inevitable during a clean period. To maintain the cleanliness over a long period of time, it is necessary to periodically clean the treads and replace the treadle devices when they become dirty. However, there are problems such as a large economic burden.

In view of the foregoing, the present invention makes it possible to separately attach and detach a tread plate and a riser of a dirty tread device at an installation site of a passenger conveyer such as an escalator, to reduce a cleaning product into small parts, and to facilitate transportation and cleaning.
