Description

Detailed Description of the Invention

The present invention relates to an escalator and a moving walkway cleaning device according to the preamble of claim 1.

Moving walkways that transport passengers over a greater distance in a plane or at a slight slope from one floor to an adjacent floor are often used at airports.

However, there are really serious problems in cleaning the moving walkways and cleaning the escalators.

Various manufacturers, like moving walkways, form escalators with different web widths and groove widths, and in particular dirt is trapped in the grooves of the ribbed bottom plate which is naturally driven forward. Also, the groove depth is different for different manufacturers.

In particular, in the case of an escalator, an escalator and a cleaning device for a moving walkway, which are driven in a start end region or an end region in which a forwardly driven escalator element emerges in the horizontal direction, have already been proposed. The cleaning device is supported stationary on the floor in front of the original escalator and is held fixed at that position, and the escalator driven forward under the cleaning member and the cleaning head is cleaned.

[0006] When cleaning an escalator or a moving walkway of another manufacturer with the above-mentioned cleaning device, an adapter having fingers protruding in conformity with the groove width and width length or groove depth of the escalator element of the manufacturer. The board must be replaced. During the cleaning process, the fingers must be brought into contact with the grooves of the escalator element to ensure that a suitable negative pressure is created during suction to actually suck the dirt out of the grooves.

It is an object of the present invention to provide an improved escalator and moving walkway cleaning device that can solve the conventional problems.

According to the present invention, the above-mentioned problems are solved by the characteristic portions shown in claims 1, 8, 12 and 15. Advantageous forms of the invention are indicated in the other claims.

The cleaning device according to the invention has a number of surprising and completely novel features over the prior art, which are already known individually, but especially in combination during the cleaning process. Show improvements.

The cleaning device according to the present invention has, on the one hand, a support leg that is attached to be displaced with respect to the cleaning head, and raises the cleaning head of the cleaning device via the support leg by applying an external force to the handgrip. Or it is excellent in that it can descend. With this configuration, the cleaning apparatus according to the present invention is configured so that it can be “advanced” from one stage of the escalator to another stage.

In another embodiment or in a complementary embodiment, the cleaning device is capable of producing an airtight function that holds a defined suction flow, independent of the manufactured shape of the escalator or moving walkway element. It is also characterized by a special plate brush.

In another and / or complementary configuration of the invention, the cleaning device according to the invention allows the escalator element to be substantially vertical not only to the horizontal tread surface, but to the adjacent tread surface of the escalator element. The end face facing toward is also found to have the special advantage that it can be cleaned as well. Further, in the present invention, the suction head and the plate brush according to the present invention provided in advance can be arranged on the other side with respect to each rotating cleaning element by the cleaning head capable of rotating by 180 degrees, and thus, the optimum suction effect and cleaning effect can be obtained. realizable.

The advantages of the cleaning device according to the invention and the possible replacement variants of the cleaning device are listed below.

Includes up to almost 100%.・ Cleaning of individual stages according to the degree of contamination (in general, it is important because the contamination of individual stages is very strong) ・ Simple maintenance-free configuration; Serviceability due to good accessibility. • (better separation of waste due to high temperatures) alongside the benefits resulting from steam cleaning;
There is no risk of excess liquid entering the escalator and causing damage.・ Small and light control unit; no transport problems. · Low price.

[0017]   A preferred embodiment of the cleaning apparatus according to the present invention will be briefly described below.

The cleaning device according to the invention relates to a manually guided cleaning device for cleaning escalators and moving walkways. In order to vertically move the so-called steering shaft in the vertical direction, a roller is pressed against the tread surface of the object to be cleaned through the support member. A steering unit, which can be adjusted in height and angle, is provided at the upper end to guide the steering unit, measure the steam supply, and switch the drive motor. Two rotating roller brushes, which have an end for contacting the floor and are provided on the shaft, carry dirt from the step groove towards the pipe provided behind the roller brush in the direction of rotation while supplying steam. The direction of rotation of the roller brushes is chosen to carry away dirt that is separated from sharply opening corners (which occur on the escalator between each moving stage). Suck dirt through a hose through a pipe into a "steam-suction-washer".

By manipulating the hand lever reachable from the steering unit, the steering unit supported on the main pipe can be swiveled by 180 degrees to be ready for the "end face" of the stage. Also in this case, it is unavoidable again that the dirt does not go into the open corner.

The operating method enabling a novel solution of the cleaning device according to the invention is shown in the preferred embodiment below.

After connecting the cleaning device according to the invention to the mains voltage, installing the steam supply and the exhaust hose, the cleaning device is very easily placed from below on a stationary escalator,
Therefore, the cleaning of the first stage of the escalator is started. The roller brush is lowered near the edge with respect to the side wall, and cleaning is started by moving the steering unit back and forth. In addition to the small rollers mounted longitudinally of the machine, laterally moving lateral rollers are mounted. Lateral rollers contacting the floor surface on the rear slope of the cleaning device allow the steering unit to be moved laterally to treat uncleaned surfaces.

First, wash all the tread surfaces of the steps (from bottom to top), then all the end surfaces (from top to bottom)
It is preferable to wash.

To this end, the steering unit can be swiveled further downwards, the washing device can be pushed forwards and can be advanced to the adjacent tier for further washing. The height rise is limited by about 12-15 steps, as the hose and cable lengths provide the working radius. In order to clean the end faces and to descend back to the starting point, a lever reachable from the steering unit allows the entire scrub head to be swiveled 180 degrees and "down" again from step to step. The escalator is advanced only in the area to be washed so that the latest 12 to 15 steps can be reached.

An embodiment of the present invention and a basic configuration of a cleaning apparatus will be described below with reference to FIGS.

The slit-shaped outlet opening 23 ′ also serves as a slider (slider) 25 at the same time. For this reason, in FIG. 2, the bristles of the roller brushes 9 ′, 9 ″ reliably contact the groove bottom portion 27 in the vertical groove 29 between the adjacent vertical ribs 33 reaching the upper edge 31 of the escalator or the moving walkway. In the open position, an outlet opening 23 ′ is formed in the cleaning head 7.

In another configuration or as a complement, another support device 35 can be provided, if desired, which further receives and supports the weight of the cleaning device in the area of the roller brush device.
The additional supporting device consists, for example, of a slider (slider) 35 juxtaposed with the roller brush 9'at least on the outer side of the end face and which looks triangular in its side view in FIG.
The slider 35 is selected to have a width such that it cannot enter the corresponding vertical groove 29 formed between the two vertical ribs 33.

If necessary, the escalator of the vertical rib 33 or the upper surface 31 of the moving sidewalk is again provided.
It is also possible to provide a preceding slider (slider) 37, for example in the form of a small-sized tube 37 ′, on which the washing head 7 is stationary and supported.

As is particularly apparent in FIG. 2, in the illustrated embodiment, two different plate brushes 41 ′ and 41 ″ are arranged facing the roller brush device 9 and against the suction plate 23.
It is possible to provide a special plate brush device 41 having

The plate brushes 41 and 41 ″, which extend over the entire width of the cleaning device, are provided with bristles of different lengths, for example. Thereby, a sufficiently good airtight function is exhibited, a sufficient negative pressure is formed between the rotating roller brush 9 and the plate brush device 41, and the suction plate 2
The soiled matter can be sucked up via the 3.

The structure of the suction plate 23 and / or the plate brush device 41 which is pivotably held by the guiding and pivoting kinematics is apparent as follows.

For this purpose, a swivel guide device 42 is provided which holds the suction plate (23) and the bristle plate device (41). As is apparent from the perspective view of FIG. 5, the swivel guide device 42 includes a shaft 9a for supporting the outer portion of the cylindrical guide device 42 'and the corresponding roller brush 9'.
And an arcuate end surface 42 ″ that is located inside and that penetrates through. In FIG. 5, a roller brush attached only to the left side is shown, but the shaft end 9a is shown on the right side, so the roller brush is not shown. Therefore, the suction plate 23 and the brush plate device 41 are attached so as to be rotatable around the axis constituted by the shaft end 9a.

Further, as is apparent from FIG. 5, another slider (slider) 36 placed on the rib upper surface 31 of the upper surface of the escalator or the moving walkway in a normal driving state is juxtaposed in both axial directions. It is arranged between the roller brushes 9 ′.

Finally, as is apparent from FIG. 5, the roller brush device 9 is protected by the cover 44 having a substantially semi-cylindrical shape that covers the upper surface of the roller brush device 9, and the cover 44 also constitutes the swivel guide device 42.

[0041]   The functions and operating methods according to the embodiments of the present invention are as follows.

The cleaning device according to the drawing of FIG. 1 is moved onto a moving walkway (in the case of a stationary moving walkway, for example) and the cleaning device advances at a slow speed on the walkway to wash the moving walkway. The wash head, which is supported on one or more slides, is then slowly pushed forward. Subsequently, the cleaning device is provided with the support device 1 on the roller 21 provided in advance.
Supported via 3.

For example, when the cleaning device is to be moved left and right on a moving sidewalk having a special width, while gripping the upper hand grip 3 and pushing it downward to lift the cleaning head 7 from the floor, Performs vertical vertical movement of the entire cleaning device. At that time, the horizontal roller 4 in which the rotating shaft is arranged so as to be deviated from the original traveling roller 21 shown in FIG. 1 by 90 degrees.

During the cleaning process, the roller brush device 9 rotates counterclockwise, so that contaminants are carried in the vertical groove 29 toward the suction plate 23. At the same time, the dirt particles are also moved forward by the subsequent plate brush, while at the same time holding the desired negative pressure for optimizing the suction process. When a lateral slider (sliding element) is provided adjacent to the end faces of the roller brushes 9 ′, 9 ″, the suction chamber is provided in front of the suction plate 23 and laterally so as to exert an additional airtight function. The slider can be extended rearward.

[0045]   The operating method for cleaning the escalator will be described below.

After the electric system of the cleaning device is connected to the power supply voltage (when the built-in battery is not used), a cleaning supply means such as a steam supply device is attached and an exhaust hose (connected to the suction plate) is connected. However, the cleaning device is very easily moved from below onto the stationary escalator to start the cleaning of the first stage of the escalator. The operation of the roller brush 9 which is lowered near the edge with respect to the side wall is started. Cleaning is performed by moving the control unit back and forth. It is possible to wash each stage of the escalator over the entire width by bringing the horizontal roller 45 into contact with the floor again toward the rear side by swinging the washing device and moving the washing device to the left or right as necessary.

Again gripping the handgrip 3 of the cleaning device, the handlegrip 3 around the support leg 13 below the steering shaft-like arrangement until the cleaning head is located above the level of the adjacent escalator stage. After swinging and turning, the entire cleaning device is moved forward by the traveling roller 21, the cleaning head is brought into contact with the floor surface of the adjacent escalator element and lifted to the adjacent step, and then the escalator step is cleaned. can do.

Next, the adjacent forward facing end wall 47 of the adjacent higher escalator element is cleaned, this cleaning process being possible only for the cleaning device according to the invention.

For this purpose, the rocking lever 49 (FIG. 4) is operated, whereby the washing head 7 is first lifted again from the floor, while performing a vertical movement. As a result, when the entire cleaning head is rotated by 180 degrees around the rotation axis that supports the cleaning head, as shown in FIG.
In addition to the plate brush and the suction plate being arranged on the right side in the side view of FIG. 6, the plate brush and the suction plate can also be arranged on the left side as shown in FIGS. The cleaning process is accurately started in the corner area between the adjacent end walls 47 of the escalator stage located below it and the escalator stage located above it, in which case a swirling motion (pressure exertion on the handgrip 3) is performed. While performing, the vertical movements of the support legs 13 'are performed, in which case the roller brush device 9 touches the vertical end wall 47 of the higher escalator stage to remove the dirt there. Aspirate through.

After the cleaning process is completed, the cleaning head 7 is returned to the starting position by rotating 180 degrees in order to clean the floor surface of the adjacent higher escalator stage. After lowering the wash head, the support legs 13 are lifted upwards, so that the support legs can likewise be supported again on the adjacent higher, but always lower, position relative to the wash head.

In this way, all the stages can be washed sequentially. In that respect, only the connection cable, in particular the current cable, the optional cleaning agent, in particular the supply line length of the vapor supply, for example with respect to the connected suction line, is limited.

Unlike the illustrated embodiment, it is also possible to handle at least semi-automatic devices in which the cleaning head can be raised and lowered automatically, for example. This can rotate the wash head by 180 degrees in the raised position as described above, and then lower again. This embodiment is not limited to manual devices, escalators or moving walkways, as well as other examples. All the above construction principles can be used individually or in common for each washing machine.
