Description

Der Reinigungsautomat für die Reinigung von industriellen Anlagen und Anlagenteilen ist insbesondere, aber nicht ausschließlich für die Reinigung von stehenden Rohrbündelapparaten vorgesehen, wobei sich die Rohrbündelapparate insbesondere in abgeschlossenen Kammern befinden, die nur über ein Mannloch zugänglich sind.The automatic cleaning machine for cleaning industrial systems and system parts is particularly, but not exclusively, intended for cleaning upright tube bundle devices, the tube bundle devices being in particular in closed chambers that are only accessible via a manhole.

Einen Reinigungsautomaten nach dem nächstkommenden Stand der Technik zeigt das Dokument US-A-3938535 .The document shows a cleaning machine according to the closest prior art US-A-3938535 .

Die Reinigung von derartigen Rohrbündelapparaten, auch Wärmeübertrager oder -tauscher genannt, aber auch von anderen industriellen Anlageteilen erfolgt nach dem Stand der Technik zumeist noch manuell. Hierzu wird beispielsweise auf EP 803 697 B1 , dort insbesondere Figur 12, verwiesen. Sie zeigt die manuelle Reinigung eines Rohrbündelapparates.The cleaning of such tube bundle devices, also called heat exchangers or heat exchangers, but also of other industrial plant parts is mostly still done manually according to the prior art. For this purpose, for example EP 803 697 B1 , there in particular Figure 12, referenced. It shows the manual cleaning of a tube bundle apparatus.

Aufgrund des hohen Wasserdrucks und auch möglicher Gefährdung durch freigesetzte Aerosole und Gefahrstoffe während der Reinigung müssen die Mitarbeiter eine persönliche Schutzausrüstung tragen. Diese behindert beim Arbeiten, schützt aber vor Schmutz und vor Verletzungen durch Wasserstrahlen. In die einzelnen Rohre eines Rohrbündelapparates wird manuell eine Lanze hineingeschoben, an derem vorderen, freien Ende eine Düse angeordnet ist, aus der das Wasser austritt. Die Reinigung erfolgt bei Wasserdrücken von typischerweise über 1000 bar, häufig noch höher. Unter Hochdruck Wasser wird Wasser mit mindestens 500 bar Druck, insbesondere mindestens 500 bar Druck verstanden. Aus der DE 34 18 835 A1 ist eine Hochdruckreinigungsvorrichtung zum Reinigen radioaktiv kontaminierter Rohrbündel bekannt. Durch die Rohre wird ein Hochdruckschlauch geschoben, der an seinem vorderen Ende eine Düse für das Reinigungswasser trägt. Die Vorrichtung ist für automatischen Betrieb bestimmt, da die zu reinigenden Rohrbündel radioaktiv kontaminiert sind und ein Aufenthalt einer Person in ihrer Nähe gesundheitsgefährdend ist.Due to the high water pressure and the possible risk from released aerosols and hazardous substances during cleaning, employees must wear personal protective equipment. This hinders work, but protects against dirt and injuries from water jets. A lance is manually pushed into the individual tubes of a tube bundle apparatus, at the front, free end of which a nozzle is arranged, from which the water exits. The cleaning takes place at water pressures of typically over 1000 bar, often even higher. High pressure water is understood to mean water with at least 500 bar pressure, in particular at least 500 bar pressure. From the DE 34 18 835 A1 a high-pressure cleaning device for cleaning radioactively contaminated tube bundles is known. A high-pressure hose with a nozzle for the cleaning water at its front end is pushed through the pipes. The device is intended for automatic operation, since the tube bundles to be cleaned are radioactively contaminated and a person staying in their vicinity is hazardous to health.

Aus der US 4 137 928 A ist eine Hochdruckreinigungsvorrichtung bekannt. Sie hat eine Hülse, die unmittelbar am Ende eines Rohres ansetzt. Sie ist für die Mechanisierung im Einsatz ausgelegt, die Lanze ist nicht frei zugänglich.From the U.S. 4,137,928 A a high pressure cleaning device is known. It has a sleeve that attaches directly to the end of a pipe. It is designed for mechanization in action, the lance is not freely accessible.

Hier setzt nun die Erfindung ein. Sie hat es sich zur Aufgabe gemacht, eine Vorrichtung zur Hochdruckreinigung zur Verfügung zu stellen, die die Nachteile der bekannten Vorrichtungen vermeidet und es ermöglicht, die Reinigung ohne unmittelbare Nähe von Personen am Reinigungsort durchzuführen, so dass die Mitarbeiter keine aufwendige persönliche Schutzausrüstung benötigen, vielmehr weit entfernt vom Reinigungsort den Reinigungsvorgang durchführen und steuern können.This is where the invention comes in. It has set itself the task of providing a device for high-pressure cleaning which avoids the disadvantages of the known devices and makes it possible to carry out cleaning without the immediate vicinity of people at the cleaning location, so that the employees do not need expensive personal protective equipment, rather be able to carry out and control the cleaning process far away from the cleaning location.

Diese Aufgabe wird gelöst durch einen Reinigungsautomaten mit den Merkmalen des Anspruchs 1.This object is achieved by an automatic cleaning machine with the features of claim 1.

Dieser Reinigungsautomat besteht aus wenigen, gut handhabbaren Teileinheiten. Die Teileinheiten können leicht voneinander getrennt und wieder miteinander verbunden werden. Die Teileinheiten sind die balkenförmige Horizontaleinheit und die Vertikalbalkeneinheit, vorzugsweise kommt der Stützfuß hinzu. Die balkenförmige Horizontaleinheit ist im Betrieb im Wesentlichen horizontal angeordnet. Von ihr steht die Vertikalbalkeneinheit quer nach oben weg. Im Wesentlichen ergibt sich eine L-förmige Anordnung. Die Vertikalbalkeneinheit wird entlang der Schienenführung verschoben, wenn der Schlitten entlang der Schienenführung bewegt wird. Durch diese Bewegung ändert sich der Massenmittelpunkt. Um dem entgegenzuwirken, ist der Gewichteschlitten vorgesehen, der in Gegenrichtung zum Schlitten arbeitet. Er wird vorzugsweise stets so gefahren, dass sich der Massenmittelpunkt im Wesentlichen nicht verschiebt. Dadurch ist eine Voraussetzung geschaffen, dass die Bewegung der Lanze unabhängig von der relativen Position der Vertikalbalkeneinheit in Bezug auf die balkenförmige Horizontaleinheit ist.This cleaning machine consists of a few easy-to-use sub-units. The sub-units can easily be separated from one another and reconnected to one another. The sub-units are the bar-shaped horizontal unit and the vertical bar unit, preferably the support foot is added. The bar-shaped horizontal unit is arranged essentially horizontally during operation. The vertical bar unit projects from it transversely upwards. Essentially, the result is an L-shaped arrangement. The vertical bar unit is moved along the rail guide when the carriage is moved along the rail guide. This movement changes the center of mass. To counteract this, the weight slide is provided, which works in the opposite direction to the slide. It is preferably always driven in such a way that the center of mass does not essentially shift. This creates a requirement that the movement of the lance is independent of the relative position of the vertical bar unit in relation to the bar-shaped horizontal unit.

In die zu reinigenden Rohre wird die Lanze motorisch eingefahren. Hierzu ist sie verschiebbar am Vertikalbalken geführt. Im Betrieb hat sie an ihrem unteren, freien Ende eine Düse. Aus dieser Düse tritt Wasser unter Hochdruck aus. Auf diese Weise werden die Rohre gereinigt, diesen Vorgang bezeichnet man auch als Bohren.The lance is driven into the pipes to be cleaned. For this purpose it is slidably guided on the vertical beam. In operation it has a nozzle at its lower, free end. Water emerges from this nozzle under high pressure. In this way the pipes are cleaned, this process is also known as drilling.

Durch die Bewegung des Schlittens entlang der Schienenführung wird die Lanze in unterschiedliche Positionen gebracht, die der Öffnung der Rohre entsprechen. Die Lanze selbst ist motorisch verschiebbar am Vertikalbalken geführt. Sie kann so in die zu reinigenden Rohre hinein bewegt werden.By moving the carriage along the rail guide, the lance is brought into different positions that correspond to the opening of the pipes. The lance itself is guided by a motor on the vertical beam. It can be moved into the pipes to be cleaned.

In einer bevorzugten Weiterbildung ist ein Stützfuß vorgesehen, der ein Basisteil, einen Schwenkantrieb und eine Aufnahme umfasst. Die Aufnahme ist mit dem Gestell lösbar verbindbar. Der Schwenkantrieb ist zwischen dem Basisteil und der Aufnahme angeordnet. Aufgrund des Schwenkantriebs kann die Aufnahme gegenüber dem Basisteil gedreht werden. Vorzugsweise erfolgt dies über beliebige Winkel, insbesondere über 360°. Wenn das Basisteil mittig zu einem Rohrbündel ausgerichtet ist, können Rohre erreicht werden, die auf einem Kreisbogen um die Mitte angeordnet sind.In a preferred development, a support foot is provided which comprises a base part, a pivot drive and a receptacle. The receptacle can be detachably connected to the frame. The swivel drive is arranged between the base part and the receptacle. Due to the swivel drive, the holder can be rotated relative to the base part. This is preferably done over any angle, in particular over 360 °. If the base part is centered on a tube bundle, tubes can be achieved which are arranged on an arc around the center.

Anstelle eines Stützfußes kann ein Fahrgestell vorgesehen sein, das sich unter der balkenfarbigen Horizontaleinheit befindet. Dabei kann das Fahrgestell einen Schwenkantrieb aufweisen, der ein Verschwenken gegenüber dem Fahrgestell um eine vertikale Achse ermöglicht. Vorzugsweise hat das Fahrgestell eine Aufnahme, wie sie der Stützfuß hat. Die Aufnahme wird lösbar mit dem Gestell verbunden, dies erfolgt vorzugsweise im Bereich der Längsmitte des Gestells, mit Abweichung plus minus 10 % der Gesamtlänge des Gestells.Instead of a support foot, a chassis can be provided, which is located under the bar-colored horizontal unit. In this case, the chassis can have a swivel drive which enables it to be pivoted relative to the chassis about a vertical axis. The chassis preferably has a receptacle such as that of the support leg. The receptacle is detachably connected to the frame, this is preferably done in the area of the longitudinal center of the frame, with a deviation plus minus 10% of the total length of the frame.

Um die Anordnung aus Vertikalbalkeneinheit und balkenförmiger Horizontaleinheit stabiler zu gestalten, ist vorzugsweise eine Stützstrebe vorgesehen, die mit ihrem einen Ende am Schlitten und mit ihrem anderen Ende am Vertikalbalken lösbar befestigt ist. Sie bildet mit der Vertikalbalkeneinheit und der balkenförmiger Horizontaleinheit ein Dreieck.In order to make the arrangement of the vertical bar unit and bar-shaped horizontal unit more stable, a support strut is preferably provided, one end of which is releasably attached to the slide and the other end to the vertical bar. It forms a triangle with the vertical bar unit and the bar-shaped horizontal unit.

In einer weiteren, vorzugsweisen Ausbildung ist eine Längsführung am Vertikalbalken vorgesehen. Ein Balkenschlitten ist entlang dieser Längsführung verschiebbar geführt. Ihm ist ein Motor bzw. Vertikalantrieb zugeordnet, der den Balkenschlitten entlang des Vertikalbalkens bewegt. Auf diese Weise kann die Lanze motorisch ein-und ausgefahren werden. In einer weiteren Verbesserung sind ein Drehantrieb für die Lanze und ein Drehanschluss für einen Hochdruck-Wasserschlauch vorgesehen. Mittels des Drehantriebs kann die Lanze um ihre Längsachse gedreht werden. Damit wird auch die an ihrem freien Ende befindliche Düse gedreht. Dies verstärkt die Reinigungswirkung. Durch den Drehanschluss wird die Drehung der Lanze vom zuführenden Wasserschlauch entkoppelt.In a further, preferred embodiment, a longitudinal guide is provided on the vertical beam. A beam carriage is slidably guided along this longitudinal guide. A motor or vertical drive is assigned to it, which moves the beam carriage along the vertical beam. In this way, the lance can be retracted and extended by a motor. In a further improvement, a rotary drive for the lance and a rotary connection for a high-pressure water hose are provided. The lance can be rotated around its longitudinal axis by means of the rotary drive. This also turns the nozzle at its free end. This increases the cleaning effect. The rotation of the lance is decoupled from the supplying water hose by the rotary connection.

Vorzugsweise ist der Reinigungsautomat mit einer Kamera und einer Beleuchtungseinheit ausgerüstet, beide sind vorzugsweise am Gestell in Nähe des Vertikalbalkens oder am Vertikalbalken angeordnet und nach unten ausgerichtet.The automatic cleaning machine is preferably equipped with a camera and a lighting unit; both are preferably arranged on the frame near the vertical bar or on the vertical bar and are oriented downwards.

Vorzugsweise hat der Reinigungsautomat eine Steuervorrichtung. Sie ist mit allen motorischen Antrieben, der Kamera, der Beleuchtungseinheit, der Wasserzuleitung usw. verbunden und steuert diese. Den motorischen Antrieben sind Sensoren zugeordnet, über die der Zustand einer Verschiebung, der Winkel einer Schwenkbewegung oder dergleichen erfasst wird. Auch diese Sensoren sind mit der Steuervorrichtung verbunden. Über die Steuervorrichtung können sämtliche Bewegungsabläufe des Reinigungsautomaten durchgeführt und erfasst werden. Die Steuervorrichtung ist kabelgebunden oder per Funk mit einem externen Bediengerät verbunden. Dieses kann sich in einer Entfernung von vielen Metern vom Reinigungsautomaten und außerhalb jeglicher Gefahrenzone befinden. Am Bediengerät ist ein Monitor vorgesehen, der das Bild einer Kamera wiedergibt. Vorzugsweise kann die Kamera auch in ihrer Bewegung gesteuert werden. Auch die Beleuchtungseinheit kann am Bediengerät geschaltet und gegebenenfalls auch ausgerichtet werden.

Das erste Ausführungsbeispiel nach den Figuren 1 und 2 sowie die zugehörige allgemeine Erläuterung nach den Figuren 3 und 4 sind skizzenhaft dargestellt. Auf diese Weise soll das Prinzip erläutert werden. Die Figuren 5-7 zeigen eine ausführbare Variante in Form des zweiten Ausführungsbeispiels.The first embodiment according to the Figures 1 and 2 as well as the associated general explanation after Figures 3 and 4 are shown in sketch form. This is the way to explain the principle. The Figures 5-7 show an executable variant in the form of the second exemplary embodiment.

Der Rohrbündelapparat besteht aus drei wesentlichen Teileinheiten, nämlich einer balkenförmigen Horizontaleinheit 20, einer Vertikalbalkeneinheit 22 und einem Stützfuß 24. Diese drei Teileinheiten lassen sich einfach voneinander separieren, getrennt transportieren und vor Ort wieder zusammenfügen.The tube bundle apparatus consists of three essential sub-units, namely a bar-shaped horizontal unit 20, a vertical bar unit 22 and a support leg 24. These three sub-units can easily be separated from one another, transported separately and reassembled on site.

Die balkenförmige Horizontaleinheit 20 hat ein Gestell 26, das im Wesentlichen aus zwei parallel zueinander verlaufenden Profilen 27 aufgebaut ist. Diese bilden eine Linearführung aus. Die balkenförmige Horizontaleinheit 20 hat weiterhin einen Wagen bzw. Schlitten 28, der sich entlang dieser Linearführung bewegt und eine Antriebseinheit 30, die den Schlitten 28 bewegt. Zudem weist die balkenförmige Horizontaleinheit 20 einen Gewichteschlitten 36 auf, der ebenfalls am Gestell 26 in Längsrichtung des Gestells 26 verschiebbar geführt ist. Er wird ebenfalls durch die Antriebseinheit 30 angetrieben. Am Gewichteschlitten 36 ist ein Gegengewicht 38 lösbar angehängt. Es können hier unterschiedliche einzelne Gewichte eingehängt und ein gewünschtes Gegengewicht 38 zusammengestellt werden.The bar-shaped horizontal unit 20 has a frame 26 which is essentially composed of two profiles 27 running parallel to one another. These form a linear guide. The bar-shaped horizontal unit 20 furthermore has a carriage or carriage 28 which moves along this linear guide and a drive unit 30 which moves the carriage 28. In addition, the bar-shaped horizontal unit 20 has a weight slide 36, which is likewise guided on the frame 26 so as to be displaceable in the longitudinal direction of the frame 26. It is also driven by the drive unit 30. A counterweight 38 is detachably attached to the weight slide 36. Different individual weights can be suspended here and a desired counterweight 38 can be put together.

Die Antriebseinheit 30 befindet sich an einem Ende des Gestells 26. Gemäß dem ersten Ausführungsbeispiel treibt sie ein Antriebsrad 32 an, das seinerseits einen Antriebsstrang 34 antreibt, der mit dem Schlitten 28 und dem Gewichteschlitten 36 verbunden ist. Vorzugsweise ist der Antriebsstrang 34 im ersten Ausführungsbeispiel eine geschlossen umlaufende Kette, ein Zahnriemen oder dergleichen. Im zweiten Ausführungsbeispiel hat die Antriebseinheit 30 ebenfalls einen Motor, der über ein Getriebe zwei Schraubenspindeleinheiten 86, 88 antreibt. Eine treibt den Schlitten 28, die andere den Gewichteschlitten 36. Hierauf wird weiter unten noch eingegangen.The drive unit 30 is located at one end of the frame 26. According to the first exemplary embodiment, it drives a drive wheel 32, which in turn drives a drive train 34 which is connected to the slide 28 and the weight slide 36. In the first exemplary embodiment, the drive train 34 is preferably a closed circulating chain, a toothed belt or the like. In the second exemplary embodiment, the drive unit 30 also has a motor which drives two screw spindle units 86, 88 via a transmission. One drives the slide 28, the other drives the weight slide 36. This will be discussed further below.

Die Vertikalbalkeneinheit 22 ist am Schlitten 28 lösbar befestigt und ragt quer zur Längsrichtung der balkenförmigen Horizontaleinheit 20 von dieser nach oben weg.The vertical bar unit 22 is releasably attached to the slide 28 and protrudes upwardly away from the bar-shaped horizontal unit 20 transversely to the longitudinal direction thereof.

Wenn die Antriebseinheit 30 aktiv ist, bewegt sie die Vertikalbalkeneinheit 22 und zugleich den Gewichteschlitten 36 entweder aufeinander zu oder voneinander weg, siehe Pfeil 42. Dadurch wird erreicht, dass ein Massenmittelpunkt des gesamten Reinigungsautomaten in horizontaler Richtung, parallel zur Längsrichtung der balkenförmigen Horizontaleinheit 20, weitestgehend unverändert bleibt, wenn eine Bewegung durch die Antriebseinheit 30 erfolgt. Es wird angestrebt, dass sich die Lage des Massenmittelpunktes in vertikaler Richtung möglichst wenig ändert, wenn die Vertikalbalkeneinheit 22 bewegt wird. Seitlich, also quer zur Längsrichtung sowohl der balkenförmigen Horizontaleinheit 20 als auch der Vertikalbalkeneinheit 22, soll sich die Lage des Massenmittelpunktes nicht verändern, wenn eine Bewegung durch die Antriebseinheit 30 erfolgt. Demgemäß sind die balkenförmige Horizontaleinheit 20 und/oder die Vertikalbalkeneinheit 22 vorzugsweise spiegelsymmetrisch zu einer Ebene die von den Längsrichtungen sowohl der balkenförmigen Horizontaleinheit 20 als auch der Vertikalbalkeneinheit 22 aufgespannt wird. Dadurch bleibt die Vertikalbalkeneinheit 22 im Wesentlichen immer in der Senkrechten, unabhängig von ihrer Bewegung entlang des Pfeils 40. Die Bewegung des Gewichteschlittens 36 ist entlang eines hierzu parallelen Pfeils 42.When the drive unit 30 is active, it moves the vertical bar unit 22 and at the same time the weight carriage 36 either towards one another or away from one another, see arrow 42. This achieves that a center of mass of the entire cleaning machine in the horizontal direction, parallel to the longitudinal direction of the bar-shaped horizontal unit 20, Remains largely unchanged when a movement takes place by the drive unit 30. The aim is for the position of the center of mass to change as little as possible in the vertical direction when the vertical bar unit 22 is moved. Laterally, that is, transversely to the longitudinal direction of both the bar-shaped horizontal unit 20 and the vertical bar unit 22, the position of the center of mass should not change when a movement is made by the drive unit 30. Accordingly, the bar-shaped horizontal unit 20 and / or the vertical bar unit 22 are preferably mirror-symmetrical to a plane which is spanned by the longitudinal directions of both the bar-shaped horizontal unit 20 and the vertical bar unit 22. As a result, the vertical bar unit 22 essentially always remains in the vertical, regardless of its movement along the arrow 40. The movement of the weight carriage 36 is along an arrow 42 parallel thereto.

Die Vertikalbalkeneinheit 22 hat einen Vertikalbalken 44 und eine Lanze 46, die verschiebbar am Vertikalbalken 44 geführt ist, siehe Pfeil 48. Zudem kann die Lanze 46 um ihre Längsrichtung gedreht werden, siehe Drehpfeil 50. Am unteren, freien Ende der 46 ist ein Aufnahmestück 52 für eine Düse vorgesehen, im zweiten Ausführungsbeispiel ist eine derartige Düse gezeigt.The vertical bar unit 22 has a vertical bar 44 and a lance 46, which is slidably guided on the vertical bar 44, see arrow 48. In addition, the lance 46 can be rotated about its longitudinal direction, see rotary arrow 50. At the lower, free end of the 46 is a receiving piece 52 provided for a nozzle, in the second embodiment such a nozzle is shown.

Der Stützfuß 24 hat ein Basisteil 54, das sich aus einem Rundflansch und einem daran befestigten Stutzen zusammensetzt. Der Stützfuß 24 hat weiterhin einen Schwenkantrieb 56, der auf dem Basisteil 54 befestigt ist. Sein Drehbereich ist mit einer Aufnahme 58 verbunden, die Teil des Stützfußes 24 ist. Diese ist leicht lösbar mit dem Gestell 26 verbunden. Eine Schwenkachse des Schwenkantriebs 56 befindet sich normalerweise in der Vertikalen und verläuft parallel zur Lanze 46. Die Schwenkbewegung erfolgt um beliebige Winkel. Sie ist mit dem Drehpfeil 50 eingezeichnet. Der genannte Massenmittelpunkt befindet sich vorzugsweise auf dieser Schwenkachse. Die Schwenkachse liegt in der oben genannten Ebene.The support foot 24 has a base part 54, which is composed of a round flange and a nozzle attached to it. The support foot 24 also has a swivel drive 56 which is fastened to the base part 54. Its area of rotation is connected to a receptacle 58 which is part of the support leg 24. This is connected to the frame 26 in an easily detachable manner. A pivot axis of the pivot drive 56 is normally located in the vertical and runs parallel to the lance 46. The pivoting movement takes place at any angle. She is with the rotating arrow 50 is drawn. Said center of mass is preferably located on this pivot axis. The pivot axis lies in the plane mentioned above.

Unter dem Reinigungsautomaten ist in Figur 1 ein Rohrbündelapparat 60 gezeigt. Das Basisteil 54 ist auf einem zentralen Kanal dieses Rohrbündelapparats 60 befestigt. Dies ist auch aus Figur 3 ersichtlich. Dort ist gezeigt, dass sich die Lanze 46 oberhalb eines Rohrs des Rohrbündelapparates 60 befindet, dieses Rohr kann gereinigt werden. Auch Fig. 4 zeigt dies skizzenhaft, zu sehen ist die Lanze 46, die als Strich dargestellt ist, aus einer unteren Düse tritt Hochdruckwasser aus, auf diese Weise wird ein Rohr gereinigt.Under the machine is in Figure 1 a tube bundle apparatus 60 is shown. The base part 54 is attached to a central channel of this tube bundle apparatus 60. This is off too Figure 3 evident. It is shown there that the lance 46 is located above a tube of the tube bundle apparatus 60; this tube can be cleaned. Also Fig. 4 shows this in a sketchy manner, the lance 46 can be seen, which is shown as a line, high-pressure water emerges from a lower nozzle, in this way a pipe is cleaned.

Das Gegengewicht 38 ist vorzugsweise so angeordnet, dass der Teil, der sich in Figur 2 links einer Längsmittellinie des Gestells 26 befindet, gleich schwer ist wie der Teil, der sich rechts dieser Längsmittellinie befindet. Anders ausgedrückt ist das Gegengewicht 38 spiegelsymmetrisch zur genannten Ebene.The counterweight 38 is preferably arranged so that the part that is in Figure 2 is located to the left of a longitudinal center line of the frame 26, has the same weight as the part which is located to the right of this longitudinal center line. In other words, the counterweight 38 is mirror-symmetrical to the plane mentioned.

Die Vertikalbalkeneinheit 22 weist eine Stützstrebe 62 auf, die mit einem unteren Ende am Schlitten 28 und mit einem oberen Ende am Vertikalbalken 44 befestigt ist. Auf diese Weise wird der Vertikalbalken 44 abgestützt und in vertikaler Position gehalten.The vertical bar unit 22 has a support strut 62 which is fastened with a lower end to the slide 28 and with an upper end to the vertical bar 44. In this way, the vertical beam 44 is supported and held in a vertical position.

Im Folgenden wird auf das zweite Ausführungsbeispiel eingegangen. Alle Ausführungen zum ersten Ausführungsbeispiel treffen auch für das zweite Ausführungsbeispiel zu, sofern nicht im Folgenden gegenteilige Ausführungen gemacht werden. Der Aufbau des Gestells 26 aus zwei parallelen Profilen 27 ist nun zu erkennen. Zu erkennen sind auch Räder 64 des Schlittens 28 und entsprechende Räder des Gewichteschlittens 36. Das Gestell 26 ist U-förmig, die beiden Profile 27 sind hinten im Bereich der Antriebseinheit 30 miteinander verbunden, vorn jedoch nicht. Dadurch ist Raum für die Bewegung des Vertikalbalkens 44. Dieser kann sich sowohl vor dem Gestell 26 als auch zwischen den beiden Profilen 27 befinden. Der Vertikalbalken 44 befindet sich im Wesentlichen oberhalb des Gestells 26, teilweise aber auch unterhalb. Er befindet sich zu 5-20 % seiner Gesamtlänge unterhalb des Gestells 26. Am Vertikalbalken 44 ist ein Balkenschlitten 66 geführt. Er wird über eine umlaufende Kette bzw. einen Riemen angetrieben, der Antrieb erfolgt über einen Vertikalantrieb 68. Am Balkenschlitten 66 sind ein Drehantrieb 70 für die Lanze 46 und ein Drehanschluss 72 für einen Hochdruck-Wasserschlauch 73 angeordnet. Dieser wird über einen Halter 74, der sich am freien Ende eines Abstützarms 76 befindet, gehalten von dort aus läuft er zu einer Buchse 78 des Stützfußes 24 und im Wesentlichen entlang der Schwenkachse durch das Basisteil 54.The second exemplary embodiment is discussed below. All statements relating to the first exemplary embodiment also apply to the second exemplary embodiment, unless statements to the contrary are made below. The structure of the frame 26 from two parallel profiles 27 can now be seen. Wheels 64 of the carriage 28 and corresponding wheels of the weight carriage 36 can also be seen. The frame 26 is U-shaped, the two profiles 27 are connected to one another at the rear in the area of the drive unit 30, but not at the front. This leaves space for the movement of the vertical bar 44. This can be located both in front of the frame 26 and between the two profiles 27. The vertical bar 44 is located essentially above the frame 26, but also partially below it. It is located 5-20% of its total length below the frame 26. A beam carriage 66 is guided on the vertical beam 44. It is driven by a revolving chain or a belt; the drive is provided by a vertical drive 68. A rotary drive 70 for the lance 46 and a rotary connection 72 for a high-pressure water hose 73 are arranged on the beam carriage 66. This is a holder 74, the is located at the free end of a support arm 76, held from there it runs to a bushing 78 of the support foot 24 and essentially along the pivot axis through the base part 54.

Die Vertikalbalkeneinheit bildet am unteren Ende des Vertikalbalkens 44 eine Führung 80 für die Lanze 46 aus.The vertical bar unit forms a guide 80 for the lance 46 at the lower end of the vertical bar 44.

In Nähe eines unteren Endes des Vertikalbalken 44 ist eine Kamera 82 angeordnet und nach unten ausgerichtet ist. Sie ist am Schlitten 28 befestigt. Weiterhin ist eine Beleuchtungseinheit 84 vorgesehen. Sie ist in Nähe eines unteren Endes des Vertikalbalkens 44 angeordnet und nach unten ausgerichtet.A camera 82 is arranged in the vicinity of a lower end of the vertical beam 44 and is directed downwards. It is attached to the slide 28. A lighting unit 84 is also provided. It is arranged in the vicinity of a lower end of the vertical bar 44 and directed downwards.

Die Antriebseinheit 30 weist eine erste Schraubenspindeleinheit 86, die mit dem Schlitten 28 verbunden ist und weiterhin eine zweite Schraubenspindeleinheit 88 auf, die mit dem Gewichteschlitten 36 verbunden ist. Vorzugsweise ist die zweite Schraubenspindeleinheit 88 gegenläufig zur ersten Schraubenspindeleinheit ist. Ein Motor der Antriebseinheit 30 treibt bei der Schraubenspindeleinheiten 86, 88 mit gleicher Umdrehungszahl und im gleichen Drehsinn an, beide Schraubenspindeleinheiten haben gleiche Steigung. Auf diese Weise wird wie im 1. Ausführungsbeispiel erreicht, dass der Massenmittelpunkt im Wesentlichen auf der Schwenkachse bleibt. In einer Alternative können gleichläufige Schraubenspindeleinheiten eingesetzt werden, wenn der Antrieb gegensinnig erfolgt.The drive unit 30 has a first screw spindle unit 86, which is connected to the slide 28, and also a second screw spindle unit 88, which is connected to the weight slide 36. Preferably, the second screw spindle unit 88 is opposite to the first screw spindle unit. A motor of the drive unit 30 drives the screw spindle units 86, 88 with the same number of revolutions and in the same direction of rotation, both screw spindle units have the same pitch. In this way, as in the first exemplary embodiment, it is achieved that the center of mass remains essentially on the pivot axis. As an alternative, co-rotating screw spindle units can be used if the drive is in opposite directions.

Die Gegengewichte 38 können von unten auf eine Tragstange des Gewichteschlittens 36 eingehängt werden, siehe hierzu Figuren 5-7. Die Gegengewichte 38 befinden sich unterhalb des Gestells 26. Am Gestell 26 ist in Nähe der Antriebseinheit 30 ein Stützstempel 90 angeordnet, dessen Länge einstellbar ist. Er steht quer nach unten vorm Gestell 26 weg. Der Stützfuß 24 steht nach unten weiter vor als das untere Ende des Vertikalbalkens 44.The counterweights 38 can be hung from below on a support rod of the weight carriage 36, see in this regard Figures 5-7 . The counterweights 38 are located below the frame 26. On the frame 26, in the vicinity of the drive unit 30, a support ram 90 is arranged, the length of which is adjustable. It stands across from the frame 26 downwards. The support foot 24 projects further downward than the lower end of the vertical beam 44.

Die balkenförmige Horizontaleinheit 20 und die Vertikalbalkeneinheit 22 weisen Abmessungen quer zu ihrer Längsrichtung auf, die innerhalb eines Kreises von 1 m, vorzugsweise von 80 cm Durchmesser liegen, sodass im demontierten Zustand des Reinigungsautomaten die balkenförmige Horizontaleinheit 20 und die Vertikalbalkeneinheit 22 durch eine Öffnung mit einem lichten Durchmesser von 1 m bzw. 80 cm hindurch transportiert werden können.The bar-shaped horizontal unit 20 and the vertical bar unit 22 have dimensions transverse to their longitudinal direction, which are within a circle of 1 m, preferably 80 cm in diameter, so that in the dismantled state of the cleaning machine, the bar-shaped horizontal unit 20 and the vertical bar unit 22 through an opening with a clear diameter of 1 m or 80 cm can be transported through.
