JP2000016744A - Cleaning method for footstep in escalator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To develop a cleaning method of a footstep in an escalator capable of cleaning with the footstep left as set up with no troublesome process and work required, and capable of washing by injection of pressure water and collecting without leaking muddy water thereof to downstairs or the like. SOLUTION: A side panel 1a is cured by a curing sheet 2 by placing an escalator X in a stop condition with each tread 1 left as mounted in the escalator, a tread surface is cleaned with a rotary brush 4a by mounting a brush cleaner 4 connected to a dust collector 3 for dust on a rubber plate Y, a cleaning unfinished part is cleaned by sliding the tread surface in a transverse direction, and the tread surface is successively cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for cleaning a step in an escalator.

[0002]

2. Description of the Related Art Conventionally, in order to paint a step board of an escalator, first, the step board is removed from the escalator, moved to a place where it can be cleaned, and cleaned. In addition, substances such as soil, dust, cotton dust, and the like are integrated with the machine oil, forming sludge-like sticky dirt, making cleaning difficult.

The escalator is formed by mixing oil with the oil automatically supplied to the tread driving chain, which oozes out to the front side. Many escalators are installed indoors. In addition, when cleaning with high-pressure water, there is a danger that washing wastewater will fall downstairs. Therefore, the work of removing, cleaning, and reattaching the work has been extremely complicated.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention can be cleaned without installing the steps as described above and with the steps installed. It is an object of the present invention to develop a method of cleaning a step in an escalator that can collect spills without leaking downstairs.

[0005]

Means for Solving the Problems To achieve the above object, a brush connected to a dust collector while the escalator is stopped in cleaning the tread on the escalator and each tread is mounted on the escalator. Attach the vacuum cleaner to the comb plate and clean it, and move the tread surface sideways to clean the uncleaned parts,
Further, a comb-shaped shroud that is closely fitted to the unevenness of the tread surface is attached to the front and rear of the nozzle, high-pressure washing is performed with hot water, and sewage is washed with a high-pressure washing and collecting device that collects waste water by vacuum. In addition, the riser surface is cleaned in the same procedure as the tread plate using a high-pressure cleaning / recovery device in which a brush enclosing plate closely fitted to the unevenness of the riser surface is mounted before and after the nozzle. The present invention has developed a method of cleaning a step in an escalator in which an escalator is sequentially operated and an uncleaned portion is exposed and cleaned.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail.
With the escalator (X) stopped, the side panel (1a) is cured with the curing sheet (2) while each step plate (1) is mounted on the escalator, and the brush cleaner is connected to the dust collector (3) for dust. (4) is mounted on the comb plate (Y), the surface of the tread plate (1) is cleaned by the rotating brush (4a), and the uncleaned portion is cleaned by sliding the tread plate surface (1) in the lateral direction. And sequentially,
This is for cleaning the tread surface.

[0007] A high-pressure washing and sewage recovery apparatus (5) is used for dirt with machine oil.
Using a tread plate wand (6), in which comb-shaped shrouds (5a) (5a ') are attached to the front and rear of the nozzle (5b) so as to fit tightly on the unevenness of the tread plate surface (1) and to be enclosed, Temporarily tightly fit the tread surface to be cleaned, and high-pressure water hose (10)
High pressure water generator (11), hot water generator (1
2) communicating with the water tank (13) to wash the tread surface with high pressure with hot water, and the cleaning waste water accumulated on the tread surface is recovered by the vacuum cleaner (9) to the waste water tank (8). Is what you do.

The brush cleaner (4) connected to the dust collector (3) used in the present invention will be described in more detail. The brush cleaner (4) is mounted on a comb plate (Y) and used. When cleaning of the portion of the mounted tread surface is completed, the tread surface of the uncleaned portion is slid and cleaned.

The dust collector (3) and the brush cleaner (4) are in communication with each other by a pipe (14), and the surface of the tread (1) is cleaned with a rotating brush (4a), and soil and the like are removed. Among them, those having large particles are collected in the hopper (4b), and those having small particles are collected in the dust collector (3) by vacuum.

A high-pressure washing and sewage recovery apparatus (5) used in the present invention will be described. A hot water generating apparatus provided with a heater from a water tank (13) storing water in a body provided with wheels or casters. (12) communicates in parallel with the high-pressure water generator (11) equipped with a pump and communicates with the step plate wand (6), while connecting the vacuum cleaner (9) and the sewage tank (8). It is a pipe connected to the nozzle (5b) of the tread wand (6) with a vacuum hose (7), and was used to wash the tread plate surface using these devices, resulting in garbage and sewage. The hot water is suctioned by the vacuum cleaner (9) and collected in the sewage tank (8).

[0011]

According to the present invention, since the operation is performed without removing the tread plate of the escalator, labor is saved, and the wand for the tread plate (6) which is closely fitted to the unevenness of the tread plate surface is used. High pressure washing using hot water, so that substances such as soil, dust, and cotton dust are integrated with the machine oil, sludge-like sticky dirt is easy to remove, and cleaning is performed without leaking the dirty water after cleaning downstairs. An extremely useful effect such as work can be achieved.
