JP2012240847A - Groove part cleaning device for demarcation line on step plate of escalator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such a problem wherein an end of a wand for a step plate used upon hot-water/high-pressure cleaning is lifted by a level difference when there is the level difference on a demarcation line, and thus the portion different in the level cannot be washed by hot-water/high-pressure as finishing cleaning.SOLUTION: A body frame 6 is fixed to a positioning metal piece 11, and a belt 4 is wound around a reel 1. The belt 4 reaches a bottom of the demarcation line of the step plate 10 via an outer periphery of a rotary plate 3, passes a guide roller 9, and reaches a winding reel 2. When an escalator is driven in a front direction, the step plate 10 moves, and wipe cleaning can be automatically carried out by the belt which is in close contact with the bottom of the demarcation line.

Description

  Concerning cleaning of escalator steps.

The escalator treadboard was cleaned by scraping dust with a rotating brush and sucking it off with a vacuum cleaner. If oil stains were found, hot water / high pressure washing / sewage collection was performed after applying detergent.
Japanese Patent No. 3084438

Reference material

  CIMEX-X46 escalator cleaner imported and sold by Zao Sangyo Co., Ltd.

  In the cleaning of the escalator footboard after several years of installation, hot water and high pressure cleaning and simultaneous wastewater recovery equipment were effective in removing dirt accumulated in the footboard and sludge-like dirt integrated with machine oil.

  There are yellow parts called demarcation lines at both ends of the escalator tread surface. This is a sign to stand slightly away from the edge so that footwear etc. is not drawn between the escalator user's moving footboard and the non-moving escalator body side plate.

  Some of these demarcation lines have a structure with consideration given to the safety of the user by adding steps to the end, giving a sense of incongruity when stepping on the end, and not standing on the end.

  If there is a step in the demarcation line, the end of the slatted womb used for hot water / high pressure washing will rise due to the step and airtightness will not be maintained, so the suction force will decrease and high pressure water will leak out of the hood. The step portion was in a state where hot water high pressure washing as finishing cleaning could not be performed.

  This demarcation line is installed in three to four rows at both ends of the footboard, and many of them are made of synthetic resin and emit a bright yellow or orange color. For this reason, it was noticed that even a little dirt remained, so there were many situations where customers were not satisfied.

Regular cleaning every few months is done by combining dust scraping with a rotary brush and a vacuum cleaner to reduce the unit cost of cleaning and the working time.

  Cleaning with a rotary brush scraping and vacuum cleaner can remove most of the dust, and in the environmental hygiene aspect of the room, it performs well, but remains in the yellow resin part of the demarcation line. Dirt was noticeable even slightly, and the appearance was not satisfied.

We thought that the method of wiping and cleaning was effective in removing slight dirt remaining in the groove portion of the demarcation line.

Since the groove portion of the demarcation line has a width of about 6 mm, the remaining slight dirt can be removed by wiping with a strip-like fiber.

When a strip-like fiber is placed in the groove and pressed from above by a plate or the like and the escalator is operated, the tread including the demarcation line moves and can be wiped and cleaned automatically.

A long belt is prepared, and the cleaning ability is secured by moving the part where dirt is attached by wiping and cleaning.

Develop a hardware to place and hold the device in the correct position.

  By attaching the dirt slightly remaining on the demarcation line to the belt-shaped fibers and moving the fibers, the surface to be adhered can always be adhered, and the yellow demarcation line becomes clean and the finishing accuracy is improved. Goes up.

  During regular cleaning, the combination of the escalator cleaner and the device can maintain environmental hygiene and satisfy the appearance. This improves safety and cleanliness for facility users and provides better service, which is extremely useful for management of the escalator design department.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is a right side perspective view of the cleaning device, in which the body frame (6) is fixed to the positioning bracket (11). (1) Wrap a belt around the reel 1 and reach the bottom of the demarcation line of the (10) stepping plate through the outer periphery of the (3) rotating plate, and take up (2) through the guide roller (9) Reached for reel 2.

  When the escalator is driven in the forward direction, the treadle moves, and wiping and cleaning can be performed automatically with a band that is in close contact with the bottom of the demarcation line.

  The right end of the fixing lever (8) is fixed to the frame with bolts. The left end is attached to the shaft of the take-up reel (2), has a ratchet function, and serves to prevent reverse rotation of the take-up reel.

  The left end of the control lever (7) is attached to the shaft of the reel (2) for taking up the reel (2) and rotates to wind up the belt (4). The end has a ratchet structure. When moved back and forth, the reel (2) rotates and the belt (4) can be taken up.

(5) The movable frame supporting the rotating plate (3) is connected to the (6) main body frame by the shaft (13) and can move up and down around (6).

  Fig. 2 is a front view, but there is a step at the end of the demarcation line of the footboard, but because the movable frame moves up and down independently, which supports the rotating plate of (3), the belt is in close contact with each bottom. ing.

  In FIG. 2, there is a step at only one step at the end, but some manufacturers have two steps at different heights. In this case as well, the movable frame (5) moves independently, so that the belt is in close contact with the bottom.

  FIG. 3 shows the apparatus installed on the landing plate of the escalator and cleaning the left and right demarcation lines simultaneously.

The positioning bracket (11) has a central expansion / contraction and is fixed by pressing both ends against the side plate of the inner deck of the escalator.

Fix the frame (6) to the positioning bracket (11) with screws and operate the escalator forward (upward in the figure) to perform the wiping work.

The perspective view of the right side shows the structure of the apparatus. In the front view, the band reaches from the reel 1 to the bottom of the demarcation line of the stepping plate 10 through the rotating plate 3. It is the figure which looked at this apparatus from the top, and is the figure which is installed in the landing plate of an escalator and is cleaning the left and right demarcation lines simultaneously. It is the figure which looked at this apparatus from the top, and is the enlarged view installed in the right side. Reel 2 of (2) is not shown because it is directly under the reel of (1).
