Description

Die Erfindung betrifft eine Versorgungseinheit für eine über mindestens einen flexiblen Schlauch anschließbare Reinigungsmaschine gemäß Oberbegriff des Anspruchs 1, sowie eine Reinigungseinrichtung mit einer solchen Versorgungseinheit.The invention relates to a supply unit for a cleaning machine that can be connected via at least one flexible hose according to the preamble of claim 1, as well as a cleaning device with such a supply unit.

Es ist bereits bekannt zum Reinigen von Flächen, beispielsweise von Kaugummi-Verschmutzungen, Trockendampf (Heißdampf) und/oder Heißwasser zu verwenden, wobei eine Versorgungseinheit Dampf bzw. das aufgeheizte Wasser bereitstellt, welches anschließend über einen flexiblen Schlauch der eigentlichen, meist handgeführten, Reinigungsmaschine zuführbar ist.It is already known to use dry steam (superheated steam) and / or hot water to clean surfaces, for example from chewing gum soiling, with a supply unit providing steam or the heated water, which is then supplied via a flexible hose to the actual, mostly hand-held, cleaning machine is feedable.

Bei einer Versorgungseinheit gemäß der WO 2007/117095 A1 ist neben dem Bereitstellen von Dampf und/oder Heißwasser auch ein Absaugen von Schmutzwasser vorgesehen, wobei alle Komponenten zu einer kompakten Baueinheit zusammengebaut sein können. Das erlaubt einen autonomen Betrieb. Diese Versorgungseinheit arbeitet elektrisch, wobei die Energiequelle eine aufladbare Batterie und die Motoren Elektromotoren sind.With a supply unit according to WO 2007/117095 A1 In addition to the provision of steam and / or hot water, the suction of dirty water is also provided, with all components being able to be assembled into a compact structural unit. This allows autonomous operation. This supply unit works electrically, the energy source being a rechargeable battery and the motors being electric motors.

Zur Verbesserung eines autonomen Betriebes und zur Bereitstellung kraftvoller Komponenten ist erfindungsgemäß eine Versorgungseinheit mit den Merkmalen des Anspruchs 1 vorgesehen.In order to improve autonomous operation and to provide powerful components, a supply unit with the features of claim 1 is provided according to the invention.

Bei den anzutreibenden Komponenten kann es sich nicht nur um die Komponenten der Versorgungseinheit selbst handeln, beispielsweise einer Wasserpumpe zum Fördern von Wasser aus dem Wassertank zur Heizeinrichtung oder dem Antrieb der Saugturbine der Saugeinrichtung, sondern vielmehr auch um Komponenten einer daran anschließbaren Reinigungsmaschine. Mit anderen Worten wird bei dieser Variante der sonst autonome Antrieb von der Reinigungsmaschine(insbesondere vollständig) in die Versorgungseinheit verlegt. Damit kann die Reinigungsmaschine selbst ohne Energiequelle, beispielsweise einen Kraftstofftank oder eine Batterie) auskommen und dennoch können dort bewegliche Komponenten wie beispielsweise Antriebsräder oder Bürsten angetrieben werden.The components to be driven can not only be the components of the supply unit itself, for example a water pump for pumping water from the water tank to the heating device or the drive of the suction turbine of the suction device, but also components of a cleaning machine that can be connected to it. In other words, in this variant, the otherwise autonomous drive from the cleaning machine (in particular completely) into the Supply unit relocated. This means that the cleaning machine itself can manage without an energy source, for example a fuel tank or a battery, and yet moving components such as drive wheels or brushes can be driven there.

Besonders bevorzugt ist weiters eine Ausführungsform, bei der die Antriebe (vorzugsweise alle Antriebe) im Wesentlichen hydraulisch erfolgen. Dazu ist ein (zentraler) Antriebsmotor, insbesondere ein Dieselverbrennungsmotor vorgesehen, dessen Kraftstofftank in der Versorgungseinheit angeordnet ist. Dieser Verbrennungsmotor treibt dann eine oder mehrere Hydraulikpumpen an, das unter Druck stehende Hydraulikfluid kann dann vielfach verwendet werden, beispielsweise zum Antrieb des Fahrantriebs der Versorgungseinheit, zum Antrieb der Wasserpumpe, der Saugturbine, des Lüfters der Heizeinrichtung oder zum Fördern von Kraftstoff aus dem Kraftstofftank in den Brenner der Heizeinrichtung.Furthermore, an embodiment is particularly preferred in which the drives (preferably all drives) are essentially hydraulic. To this end, a (central) drive motor, in particular a diesel internal combustion engine, is provided, the fuel tank of which is arranged in the supply unit. This internal combustion engine then drives one or more hydraulic pumps, the pressurized hydraulic fluid can then be used in many ways, for example to drive the drive of the supply unit, to drive the water pump, the suction turbine, the fan of the heating device or to pump fuel from the fuel tank the burner of the heating device.

Ebenso kann das unter Druck stehende Hydraulikfluid dazu verwendet werden, über eine flexible Hydraulikleitung auch bewegbare Komponenten der über eine flexible Schlauchleitung angeordneten Reinigungsmaschine anzutreiben.The pressurized hydraulic fluid can also be used to drive movable components of the cleaning machine arranged via a flexible hose line via a flexible hydraulic line.

Bei einer besonderen Ausführungsform führen dann also im Wesentlichen drei Typen von Leitungen zur Reinigungsmaschine.

  • eine Hydraulikleitung zum Antrieb bewegbarer Komponenten
  • eine Heißdampf (Trockendampf)/Heißwasserleitung zur Reinigungsmaschine hin und
  • eine Saugleitung zum Absaugen von Schmutzwasser von der Reinigungsmaschine weg zur Versorgungseinheit zurück.
In a particular embodiment, essentially three types of lines then lead to the cleaning machine.
  • a hydraulic line for driving movable components
  • a superheated steam (dry steam) / hot water pipe to the cleaning machine and
  • a suction line for sucking dirty water away from the cleaning machine and back to the supply unit.

Die Erfindung ist nicht auf einen Verbrennungsmotor als zentrale Antriebsquelle beschränkt. Es sind auch andere Antriebe durchaus denkbar und möglich. Besonders bevorzugt sind allerdings Ausführungsformen, bei denen die Versorgungseinheit autonom arbeitet, also von außen keine weitere Energiezufuhr benötigt, sondern umgekehrt ihre Energie den Reinigungsmaschinen zur Verfügung stellt.The invention is not limited to an internal combustion engine as the central drive source. Other drives are also quite conceivable and possible. Particularly preferred, however, are embodiments in which the supply unit works autonomously, that is to say no further ones from the outside Energy supply is required, but conversely, its energy is made available to the cleaning machines.

Entsprechend weit ist der Begriff "flexibler Schlauch" oder "Leitung" zu sehen. Diese Bauteile dienen nicht nur dazu, Fluide zu transportieren, wie beispielsweise Heißwasser, Dampf oder unterdruckstehendes Hydraulikfluid sowie Schmutzwasser, vielmehr ist der Begriff "flexibler Schlauch" oder "Leitung" auch so zu sehen, dass er einen Mehrfachschlauch umfasst, beispielsweise zum Zuführen von Hydraulikfluid zurThe term "flexible hose" or "line" is to be seen correspondingly broadly. These components are not only used to transport fluids, such as hot water, steam or negative pressure hydraulic fluid as well as dirty water, but rather the term "flexible hose" or "line" should also be understood to include a multiple hose, for example for the supply of hydraulic fluid to

Reinigungsmaschine und zum Abführen von Hydraulikfluid von der Reinigungsmaschine. Der Begriff "flexibler Schlauch" oder "Leitung" ist weiters so zu sehen, dass auch elektrische Leitungen unter diesen Begriff fallen sollen.Cleaning machine and for discharging hydraulic fluid from the cleaning machine. The term "flexible hose" or "line" should also be seen in such a way that electrical lines should also fall under this term.

Antriebe mit Dampf sind auch möglich.Steam drives are also possible.

Die in Figur 1 gezeigte Versorgungseinheit 1 dient zum Versorgen von Reinigungsmaschinen R1, R2, wie sie in den Figuren 1a und 1b als Alternativen dargestellt sind. Der Anschluss erfolgt über flexible Schläuche 12, die im Folgenden noch näher beschrieben werden.In the Figure 1 The supply unit 1 shown serves to supply cleaning machines R1, R2, as they are in the Figures 1a and 1b are shown as alternatives. The connection is made via flexible hoses 12, which are described in more detail below.

Die Versorgungseinheit selbst weist erfindungsgemäß einen Wassertank 2 für Frischwasser auf. Der Tank ist platzgünstig im Wesentlichen quaderförmig ausgebildet und weist einen Einfüllstutzen 2a sowie Füllstandssensoren 2b auf.According to the invention, the supply unit itself has a water tank 2 for fresh water. The tank is essentially cuboid-shaped to save space and has a filler neck 2a and fill level sensors 2b.

Vom Wassertank 2 führt eine Leitung 3 zum "Power-Modul 4", das im Folgenden anhand der Figur 2 noch näher erläutert werden wird.From the water tank 2, a line 3 leads to the "power module 4", which is described below using the Figure 2 will be explained in more detail.

In die Leitung 3 kann ein Wasserfilter 4 eingebaut sein. Über eine Zusatzleitung 5 kann Entkalkungsmittel oder auch Reinigungsmittel oder andere Zusatzstoffe zudosiert werden.A water filter 4 can be built into the line 3. Decalcifying agent or cleaning agent or other additives can be added via an additional line 5.

Weiters zeigt die Figur 1 einen Kraftstofftank zur Aufnahme von fossilem Kraftstoff, insbesondere Diesel. Dieser Kraftstofftank 6 weist einen Einfüllstutzen 6a auf. Er ist ebenfalls platzsparend quaderförmig ausgebildet.Furthermore shows the Figure 1 a fuel tank for holding fossil fuel, especially diesel. This fuel tank 6 has a filler neck 6a. It is also designed in a cuboid shape to save space.

Darüber hinaus gibt es noch einen Schmutzwassertank 7 mit einem Ablauf 7a, der über ein nicht gezeigtes Ventil öffenbar ist. Der Schmutzwassertank 7 weist einen Füllstandssensor 7b auf.In addition, there is a dirty water tank 7 with an outlet 7a which can be opened via a valve (not shown). The dirty water tank 7 has a level sensor 7b.

Die gesamte Versorgungseinheit ist selbstfahrend ausgebildet. Sie weist dazu Räder 8 auf, wobei das hintere Räderpaar 8 über einen Hydraulikmotor antreibbar ist.The entire supply unit is designed to be self-propelled. To this end, it has wheels 8, the rear pair of wheels 8 being drivable via a hydraulic motor.

Die Vorderräder sind lenkbar ausgebildet, wobei der Lenkeinschlag über eine Deichsel 10 festlegbar ist. An der Deichsel 10 ist eine Bedienkonsole 11 angeordnet, über die sich die wesentlichen Komponenten der Versorgungseinheit steuern lassen.The front wheels are designed to be steerable, with the steering angle being able to be fixed via a drawbar 10. An operating console 11 is arranged on the drawbar 10, via which the essential components of the supply unit can be controlled.

Die wesentlichen Komponenten der Versorgungseinheit (bis auf die Tanks) sind zu einer Baueinheit zusammengefasst, wobei der Tragrahmen aus mehreren Trägern aufgebaut ist, die einen Innenraum umgeben.The essential components of the supply unit (with the exception of the tanks) are combined to form a structural unit, the support frame being made up of several carriers that surround an interior space.

Die Träger können aus Profilen, vorzugsweise Hohlprofilen mit rechteckigem Querschnitt ausgebildet sein. Insgesamt erstrecken sich die Träger des Tragrahmens 4a günstigerweise entlang des Seiten eines gedachten Quaders. Der gesamte Tragrahmen 4a samt den darin enthaltenen Komponenten bildet das sogenannte "Power-Modul", das auch gesondert von den Tanks 2, 6 und 7 für Montage- oder Servicezwecke bewegbar ist.The carriers can be formed from profiles, preferably hollow profiles with a rectangular cross section. Overall, the carriers of the support frame 4a expediently extend along the side of an imaginary cuboid. The entire support frame 4a including the components contained therein forms the so-called "power module", which can also be moved separately from the tanks 2, 6 and 7 for assembly or service purposes.

Im Übrigen weisen gegebenenfalls auch die Reinigungsmaschinen der Figuren 1a und 1b solche Bedienkonsolen auf, um Funktionen steuern zu können. Die Datenübertragung kann entweder per Funk oder über nicht dargestellte Leitungen erfolgen.Otherwise, the cleaning machines may also have the Figures 1a and 1b such control consoles on to control functions can. The data can be transmitted either by radio or via lines not shown.

Die in Figur 1a dargestellte Reinigungsmaschine wird später anhand der Figur 3 noch näher erläutert. Für die Übersichtsdarstellugn der Figur 1, 1a, 1b sei folgendes erwähnt:
Die Reinigungsmaschine gemäß der Figur 1a wird von der Versorgungseinheit gemäß der Figur 1 über flexible Schläuche 12 mit verschiedensten Fluiden versorgt.In the Figure 1a cleaning machine shown is later based on the Figure 3 explained in more detail. For the overview of the Figure 1, 1a, 1b the following should be mentioned:
The cleaning machine according to the Figure 1a is operated by the supply unit according to Figure 1 Supplied with various fluids via flexible hoses 12.

Zunächst ist ein flexibler Schlauch 13 vorgesehen, der als Hydraulikdoppelschlauch ausgebildet ist und über Anschlüsse 14 (Steckkupplungen) lösbar mit der Versorgungseinheit 1 bzw. der Reinigungsmaschine gemäß der Figur 1 verbindbar ist. Das darin geführte unter Druck stehende Hydraulikfluid dient zum Antrieb von bewegbaren Komponenten, insbesondere von Bürsten, wie diese anhand der Figur 3 später noch genauer beschrieben werden wird.First, a flexible hose 13 is provided, which is designed as a hydraulic double hose and can be detached via connections 14 (plug-in couplings) with the supply unit 1 or the Cleaning machine according to Figure 1 is connectable. The pressurized hydraulic fluid guided therein is used to drive movable components, in particular brushes, such as those shown in FIG Figure 3 will be described in more detail later.

Weiters ist ein flexibler Schlauch 15 vorgesehen, der zur Zufuhr von Heißwasser oder Dampf von der Versorgungseinheit zur Reinigungsmaschine gemäß der Figur 1a dient. Die Anschlüsse können ebenfalls über lösbare Steckkupplungen 16 erfolgen.Furthermore, a flexible hose 15 is provided which is used to supply hot water or steam from the supply unit to the cleaning machine according to FIG Figure 1a serves. The connections can also be made via detachable plug-in couplings 16.

Schließlich gibt es noch einen Schmutzwasserschlauch 17, der über Steckkupplungen 18 lösbar anschließbar ist. Er dient zur Abfuhr von Schmutzwasser zur Versorgungseinheit hin.Finally, there is also a dirty water hose 17 which can be detachably connected via plug-in couplings 18. It is used to discharge dirty water to the supply unit.

An die mobile Versorgungseinheit gemäß Figur 1 kann aber nicht nur eine Type von Reinigungsmaschine angeschlossen werden. Es sind auch andere Typen anschließbar, beispielsweise jene der Figur 1b, die konkret zur Unkrautvernichtung dient und einfacher ausgebildet ist als jene Reinigungsmaschine der Figur 1a. Sie weist nämlich keine hydraulisch angetriebenen Komponenten und auch keine Schmutzwasserabfuhr auf, sondern lediglich eine Zufuhrleitung 15' für Heißdampf/Trockendampf.To the mobile supply unit according to Figure 1 but not only one type of cleaning machine can be connected. Other types can also be connected, for example those of the Figure 1b , which specifically serves to kill weeds and is more simply designed than the cleaning machine of Figure 1a . This is because it has no hydraulically driven components and also no waste water discharge, but only a supply line 15 'for superheated steam / dry steam.

Die Figur 2 zeigt die Versorgungseinheit 1 anhand eines Ausführungsbeispiels im größeren Detail, wobei vor allem der sogenannte "Power-Modul 4" mit seinem inneren Aufbau schematisch detaillierter dargestellt ist. Ansonsten tragen die gleichen Teile die gleichen Bezugsziffern wie in Figur 1.The Figure 2 shows the supply unit 1 on the basis of an exemplary embodiment in greater detail, with the so-called “power module 4” in particular being shown schematically in greater detail with its internal structure. Otherwise, the same parts have the same reference numbers as in Figure 1 .

Die Versorgungseinheit 1 weist erfindungsgemäß einen Wassertank 2 sowie eine Heizeinrichtung 19 zum Aufheizen von Wasser aus dem Wassertank 2 auf. Eine Wasserpumpe 20 in der Wasserleitung 30 dient zum Fördern von Wasser aus dem Wassertank 2 zur Heizeinrichtung 19.According to the invention, the supply unit 1 has a water tank 2 and a heating device 19 for heating water from the water tank 2. A water pump 20 in the water line 30 is used to convey water from the water tank 2 to the heating device 19.

Der Ausgang der Heizeinrichtung 19 steht mit einem Heißwasser- und/oder Dampfanschluss 16 in Verbindung. Neben Heißwasser mit knapp 100°C kann auch überhitzter Dampf mit höheren Temperaturen (z.B. zwischen 130°C und 180°C) bereitgestellt werden.The output of the heating device 19 is connected to a hot water and / or steam connection 16. In addition to hot water at almost 100 ° C, superheated steam at higher temperatures (e.g. between 130 ° C and 180 ° C) can also be provided.

Weiters ist ein Schmutzwassertank 7 vorgesehen. Dieser Schmutzwassertank steht über eine Schmutzwasserleitung 21 mit einer Saugeinrichtung 22 in Verbindung, die dazu dient, über einen flexiblen Schlauch, der an den Schmutzwasseranschluss 18 anschließbar ist, Schmutzwasser von einer Reinigungsmaschine abzusaugen und letztlich in den Schmutzwassertank 7 zu bringen.A waste water tank 7 is also provided. This waste water tank is connected to a suction device 22 via a waste water line 21, which is used to suck off waste water from a cleaning machine via a flexible hose that can be connected to the waste water connection 18 and ultimately to bring it into the waste water tank 7.

Zum Antrieb der verschiedenen Komponenten der Versorgungseinheit 1 und/oder der anschließbaren Reinigungsmaschine gemäß der Figur 1a, ist ein (zentraler) Antrieb vorgesehen, der im Wesentlichen einen Dieselverbrennungsmotor M sowie - beim dargestellten Beispiel - drei Hydraulikpumpen 23, 24 und 25 aufweist.To drive the various components of the supply unit 1 and / or the connectable cleaning machine according to FIG Figure 1a , a (central) drive is provided, which essentially has a diesel internal combustion engine M and - in the example shown - three hydraulic pumps 23, 24 and 25.

Der Kraftstofftank 6 für den Verbrennungsmotor M ist Teil der Versorgungseinheit, womit diese autonom arbeiten kann. Das heißt, sie braucht von außen keine weitere Energiezufuhr, beispielsweise über ein Starkstromkabel. Umgekehrt kann die Versorgungseinheit, die letztlich aus dem Kraftstoff entnommene Energie dazu verwendet werden, Heißwasser oder Dampf zu bilden, Komponenten anzutreiben, sei es in der Versorgungseinheit selbst oder in der daran angeschlossenen Reinigungsmaschine (wie beispielsweise der Bürsten gemäß der Reinigungsmaschine der Figur 1a bzw. 3).The fuel tank 6 for the internal combustion engine M is part of the supply unit, with which it can work autonomously. This means that it does not need any additional energy supply from the outside, for example via a power cable. Conversely, the supply unit, the energy ultimately taken from the fuel can be used to generate hot water or steam, to drive components, be it in the supply unit itself or in the cleaning machine connected to it (such as the brushes according to the cleaning machine of the Figure 1a or 3).

Wie schon die Figur 1 gezeigt hat, sind die Tanks quaderförmig ausgebildet und nur zur besseren Darstellung in Figur 2 separiert dargestellt. In Wirklichkeit sind sie so wie in Figur 1 nahe Wand an Wand aneinander gereiht, knapp neben dem sogenannten "Power-Modul 4".Like that Figure 1 has shown, the tanks are cuboid and only for better illustration in Figure 2 shown separately. In reality they are like in Figure 1 Lined up close to one another wall to wall, just next to the so-called "Power Module 4".

Die Versorgungseinheit 1 weist Räder 8 auf, von denen die Hinterräder über einen Hydraulikmotor H angetrieben sind. Zum Antrieb der Hinterräder über den Hydraulikmotor H ist die Hydraulikpumpe 25 vorgesehen, von der eine Leitung über ein Regelventil 26 zum Hydraulikmotor führt.The supply unit 1 has wheels 8, of which the rear wheels are driven via a hydraulic motor H. To drive the rear wheels via the hydraulic motor H, the hydraulic pump 25 is provided, from which a line leads via a control valve 26 to the hydraulic motor.

Die Steuerleitungen für das Regelventil 26 und auch die anderen Ventile sind der Übersichtlichkeit halber nicht dargestellt. Es ist eine elektronische Steuereinheit vorgesehen (ebenfalls nicht dargestellt), die entweder in der Versorgungseinheit oder extern angeordnet sein kann. Letztlich geht es darum, über elektrische Steuersignale die Ventile zu steuern. Grundsätzlich ist auch eine Handsteuerung der Ventile denkbar und möglich.The control lines for the regulating valve 26 and also the other valves are not shown for the sake of clarity. An electronic control unit is provided (also not shown), which can be arranged either in the supply unit or externally. Ultimately, it is a matter of controlling the valves using electrical control signals. In principle, manual control of the valves is also conceivable and possible.

Der Antrieb ist übrigens so ausgebildet, dass bei geschlossenem Ventil 26 eine Bremsfunktion im Sinne einer Handbremse erzielt wird. Das heißt, auch bei abschüssigen Stellen wird die Versorgungseinheit gehalten, ohne dass es einer zusätzlichen Bremse bedarf.The drive is designed in such a way that when the valve 26 is closed, a braking function in the sense of a handbrake is achieved. This means that the supply unit is held even on sloping spots without the need for an additional brake.

Während die in den Figuren 1 und 2 dargestellte Ausführungsform der erfindungsgemäßen Versorgungseinheit selbstfahrend ausgebildet ist, ist auch eine nicht-selbstfahrende Konstruktion denkbar und möglich. Sie wird dann als Baueinheit auf die Ladefläche oder das Fahrgestell des Fahrzeugs insbesondere eines Lastkraftwagens für Kommunalzwecke aufgeladen.While those in the Figures 1 and 2 The illustrated embodiment of the supply unit according to the invention is designed to be self-propelled, a non-self-propelled construction is also conceivable and possible. It is then loaded as a structural unit on the loading area or the chassis of the vehicle, in particular a truck for municipal purposes.

Der Dieselmotor M weist einen Nichtdargestellten elektrischen Anlasser auf und erhält über die Dieselleitung 26 den Kraftstoff. Er kann in seiner Motorleistung über eine nichtdargestellte Regeleinrichtung geregelt sein.The diesel engine M has an electric starter (not shown) and receives the fuel via the diesel line 26. Its engine output can be regulated by a control device (not shown).

Neben der bereits beschriebenen Hydraulikpumpe 25 für den Fahrantrieb der Versorgungseinheit treibt der Dieselmotor M noch zwei weitere Hydraulikpumpen 23 und 24 an, die auf einer gemeinsamen Welle sitzen können.In addition to the already described hydraulic pump 25 for driving the supply unit, the diesel engine M drives two further hydraulic pumps 23 and 24, which can be seated on a common shaft.

Die Hydraulikpumpe 23 dient über ein Steuerventil 27 zum Antrieb des hydraulischen Lüftermotors H1 der Saugeinrichtung 22.The hydraulic pump 23 is used via a control valve 27 to drive the hydraulic fan motor H1 of the suction device 22.

Die Hydraulikpumpe 24 dient zur Versorgung der externen Reinigungsmaschine über den Hydraulikanschluss 14. Eine Regelung kann über das Ventil 28 erfolgen. An dieser Stelle sei erwähnt, dass das Ölreservoir aus Übersichtlichkeitsgründen nicht dargestellt ist. Es ist schematisch durch ein liegendes U mit der Bezugsziffer 29 angedeutet.The hydraulic pump 24 serves to supply the external cleaning machine via the hydraulic connection 14. Regulation can take place via the valve 28. At this point it should be mentioned that the oil reservoir is not shown for reasons of clarity. It is indicated schematically by a horizontal U with the reference number 29.

Die Hydraulikpumpe 25 dient nicht nur zum Antrieb der Räder 8, sondern auch für drei weitere "Verbraucher". Diese sind die folgenden:

  • eine Wasserpumpe 20 mit einem Hydraulikmotor, die über ein Ventil 30 ansteuerbar ist.
  • Weiters ist ein Lüfter L der Heizeinrichtung 19 über ein Ventil 31 ansteuerbar. Auch dieser Lüfter L ist hydraulisch angetrieben.
  • Schließlich ist noch eine Pumpe P2 vorgesehen, die über ein Ventil 32 angetrieben ist. Diese Pumpe P2 dient zum Fördern von Kraftstoff aus dem Kraftstofftank 6 zum nicht näher dargestellten Brenner der Heizeinrichtung 19.
The hydraulic pump 25 is not only used to drive the wheels 8, but also for three other "consumers". These are the following:
  • a water pump 20 with a hydraulic motor, which can be controlled via a valve 30.
  • Furthermore, a fan L of the heating device 19 can be controlled via a valve 31. This fan L is also driven hydraulically.
  • Finally, a pump P2 is also provided, which is driven via a valve 32. This pump P2 serves to convey fuel from the fuel tank 6 to the burner of the heating device 19, which is not shown in detail.

Aus dem Vorstehenden ist zu sehen, dass der Begriff "Hydraulikmotor" sehr breit zu sehen ist. Er umfasst auch Pumpen, die mit Hydraulikfluid angetrieben werden.From the above it can be seen that the term "hydraulic motor" can be seen very broadly. It also includes pumps that are driven by hydraulic fluid.

Gegenüber einem auch denkbaren elektrischen Antrieb hat der hydraulische Antrieb den Vorteil geringer Baugröße und eines geringeren Gewichts. Auch sehr kräftige Komponenten mit hoher Leistung lassen sich einfach steuern.Compared to a conceivable electric drive, the hydraulic drive has the advantage of being small in size and lower in weight. Even very powerful components with high performance can be easily controlled.

Die Figur 3 zeigt ein Ausführungsbeispiel einer handgeführten Reinigungsmaschine R1 wie sie ähnlich auch in Figur 1a dargestellt ist.The Figure 3 shows an embodiment of a hand-held cleaning machine R1 similar to that in FIG Figure 1a is shown.

Die handgeführte Reinigungsmaschine R1 weist einen Handgriff 33 mit allfälligen nicht dargestellten Bedienelementen sowie eine Haupträderpaar 34 und Stützräder 35 auf.The hand-held cleaning machine R1 has a handle 33 with any operating elements (not shown) and a pair of main wheels 34 and support wheels 35.

Weiters weist die handgeführte Reinigungsmaschine gemäß Figur 3 einen Anschluss 14 auf, über den eine flexible Hydraulikleitung anschließbar ist. Über diese Hydraulikleitung kann der Hydraulikmotor H2 angetrieben werden, der seinerseits eine Reinigungsbürste 36 oder mehrere gekoppelte Bürsten antreibt.The hand-held cleaning machine according to FIG Figure 3 a connection 14 via which a flexible hydraulic line can be connected. The hydraulic motor H2, which in turn drives a cleaning brush 36 or several coupled brushes, can be driven via this hydraulic line.

Die Drehrichtung der Reinigungsbürste 36 bzw. bei mehreren Pumpen die Drehrichtung einer, mehrerer oder aller Bürsten kann von der Bedienperson geändert werden. Es ist auch möglich, dass eine elektronische Steuereinheit die Drehrichtung der Bürsten automatisch in vorgegebenen Zeitabständen verändert.The direction of rotation of the cleaning brush 36 or, in the case of several pumps, the direction of rotation of one, several or all of the brushes can be changed by the operator. It is also possible for an electronic control unit to automatically change the direction of rotation of the brushes at predetermined time intervals.

Zur Umkehr der Drehrichtung kann bei einem Hydraulikmotor eine geeignete Ventilkombination vorgesehen sein, die den Hydraulikmotor bei umgekehrter Drehrichtung einfach auf unterschiedlichen Leitungen und mit unter Druck stehenden Hydrauliköl beaufschlagt.In order to reverse the direction of rotation, a suitable valve combination can be provided in a hydraulic motor, which, when the direction of rotation is reversed, simply acts on the hydraulic motor on different lines and with pressurized hydraulic oil.

Die Drehzahl der Bürsten bewegt sich vorzugsweise zwischen 50 und 90 Umdrehungen pro Minute, ganz bevorzugt in der Größenordnung von 70 Umdrehungen pro Minute. Es hat sich gezeigt, dass in diesem Drehzahlbereich vor allem im Außenbereich auf Straßen oder Gehsteigen eine hervorragende Entfernung von auf dem Boden klebenden Verunreinigungen, insbesondere von Kaugummiresten, möglich ist.The speed of the brushes is preferably between 50 and 90 revolutions per minute, very preferably in the order of magnitude of 70 revolutions per minute. It has been shown that in this speed range, especially outdoors on roads or sidewalks, excellent removal of dirt stuck to the floor, in particular chewing gum residue, is possible.

Der Dampf bzw. das Heißwasser kann dann an einer geeigneten Stelle auf die zu reinigende Fläche aufgebracht werden. Der Dampf aus dem Kessel, dessen Kesseltemperatur beispielsweise 170°C beträgt, entspannt sich im Bereich des Arbeitsgerätes vor dem Auftreffen auf dem Boden auf eine Temperatur von vorzugsweise zwischen 90°C und 120°C, vorzugsweise zwischen 92°C und 110°C. Es hat sich gezeigt, dass in diesem Temperaturbereich wiederum eine hervorragende Entfernung von Kaugummiresten möglich ist.The steam or hot water can then be applied to the surface to be cleaned at a suitable point. The steam from the boiler, the boiler temperature of which is 170 ° C, for example, relaxes in the area of the implement before it hits the ground to a temperature of preferably between 90 ° C and 120 ° C, preferably between 92 ° C and 110 ° C. It has been shown that in this temperature range an excellent removal of chewing gum residues is again possible.

Schließlich weist die Reinigungsmaschine gemäß Figur 3 einen Anschluss 18 für einen flexiblen Schlauch 17 zum Absaugen aus einem Absaugbereich 18a der Reinigungsmaschine R1 auf.Finally, the cleaning machine according to Figure 3 a connection 18 for a flexible hose 17 for suction from a suction area 18a of the cleaning machine R1.

Insgesamt können bei der Erfindung zum Antrieb der beweglichen Komponenten sowohl hydraulische Antriebe, wie in den Figuren 1, 1a, 2 und 3 sowie Antriebe mit Dampf oder Mischungen davon vorgesehen sein.Overall, in the invention for driving the movable components, both hydraulic drives, as in the Figures 1, 1a , 2 and 3 as well as drives with steam or mixtures thereof can be provided.

Die Erfindung betrifft insbesondere auch die Verwendung einer Versorgungseinheit bzw. einer Reinigungsmaschine zum Entfernen von Verschmutzungen auf im Außenbereich liegenden Flächen, insbesondere Straßen und/oder Gehsteigen. Vor allem ist es damit möglich, Schmutzreste hervorragend zu entfernen, insbesondere Kaugummireste.In particular, the invention also relates to the use of a supply unit or a cleaning machine for removing dirt from surfaces located in the outer area, in particular streets and / or sidewalks. Above all, it is possible to remove dirt residues in an excellent manner, in particular chewing gum residues.
