(57) [Summary] [Purpose] To provide an attachment of a tip portion of an escalator cleaning device capable of cleaning with an escalator step installed by maintaining airtightness and reliably collecting sewage. [Structure] One or more high-pressure water ejection nozzles connected to the high-pressure water supply hose from the escalator cleaning device main body and a suction port connected to a dirty water suction hose connected to the main body are attached to the tip end attachment of the escalator cleaning device. A front end attachment of an escalator cleaning device, comprising a plurality of recesses provided at front and rear edges of the attachment, the recesses being adapted to a large number of protrusions formed in steps of the escalator.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tip end attachment of an escalator cleaning device for cleaning an escalator step.

[0002]

[Prior art]

 Dirt on the treads and risers of the escalator is a sludge-like, greasy dirt in which substances such as soil, dust, and cotton dust are integrated with machine oil. To remove this sludge-like dirt, it is necessary to use a lot of solvents and detergents. Therefore, there is a danger that cleaning sewage will fall downstairs if the escalator is cleaned indoors, so the steps of the escalator were removed, washed, and reattached.

[0003]

[Problems to be solved by the device]

 However, in order to remove and clean the steps of the escalator one by one, it requires a difficult work, a work time associated therewith, and a great cost.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the tip of an escalator cleaning device that can be cleaned while the steps of the escalator are installed by maintaining airtightness and reliably collecting sewage. The purpose is to provide a partial attachment.

[0005]

[Means for Solving the Problems]

 The tip attachment of the escalator cleaning device of the present invention is one or more high pressure water ejection nozzles connected to the high pressure water supply hose from the body of the escalator cleaning device, and the sewage connected to the body of the escalator cleaning device. A tip of an escalator cleaning device that has a suction port connected to a suction hose, and has a plurality of recesses at the front and rear edges of the attachment that are compatible with a number of ridges formed on the steps of the escalator. It is an attachment.

[0006]

[Action]

 In the tip attachment of the escalator cleaning device with the above configuration, the suction port is connected to the dirty water suction hose, the high-pressure water ejection nozzle is connected to the high-pressure water supply hose, and the recess at the tip of the edge before and after the attachment is While fitting along the ridges formed on the steps of the escalator and moving along the ridges formed on the steps, high-pressure water is sprayed from the high-pressure water ejection nozzle for cleaning, and at the same time Suck dirty water through the suction port and clean it so that the dirty water does not leak.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire escalator cleaning device, and the attachment (1) of the present invention is attached to the tip portion thereof. 2 is a side view of the attachment of the present invention, FIG. 3 is a front view thereof, and FIG. 4 is a bottom view thereof. As shown in FIGS. 2 to 4, two high-pressure water ejection nozzles (2) are provided and one suction port (3) is provided. When the front and rear edges (4) of the lower part of the attachment (1) come into contact with the step of the escalator, the airtightness inside the attachment (1) is ensured by conforming to the many ridges formed in the step. A plurality of recesses (5) are provided for retention.

In addition, in FIG. 2, a hose (6) for sucking dirty water is connected to the suction port (3) of the attachment (1), and high pressure water is supplied to the connection portion (2a) of the high pressure water ejection nozzle (2). It is shown that the hoses (7) are each connected. As shown in Fig. 1, a lever (8) that can be operated such as temporarily stopping the supply of high pressure water from the high pressure water supply hose (7) is attached to the middle part of the dirty water suction hose (6). is there. The dirty water suction hose (6) and the high-pressure water supply hose (7) are connected to the cleaning device body (9).

Although not shown, a high-pressure water supply tank, a heater, a waste water tank, a vacuum motor, etc. are provided in the main body of the cleaning device (9) to supply hot water containing detergent with high-pressure water to wash the waste water. Has the function of sucking and accumulating.

The recess (5) of the attachment (1) is fitted into a number of ridges formed in the step of the escalator to maintain the airtightness inside the attachment (1) and to release the high pressure water from the high pressure water ejection nozzle (2). Of the cleaning water and suction from the cleaning waste water suction port (3) at the same time, and the attachment (1) can be moved along the many ridges formed on the steps of the escalator to clean the cleaning waste water without leaking. can do.

[0011]

[Effect of device]

 According to the present invention, the attachment is provided with a suction port and a high-pressure water ejection nozzle, and the front and rear edge tips of the attachment are provided with a plurality of recesses adapted to the many ridges formed on the step of the escalator. Therefore, it is possible to wash sludge-like dirt that is difficult to remove while keeping the airtightness inside the attachment, and to prevent wash water from leaking. Therefore, there is an extremely useful effect that the escalator can be cleaned with the stepped portion installed.
