The slurry system vehicle has a storage surface (18) for the hose above the slurry tank (14), and a slewing and derricking telescopic hose boom. Driving rollers extend and retract the hose, which slides over the storage surface. The latter is fixed to the tank, and a slewing ring (34) is mounted on the top of the latter, clear of the surface and on a vertical axis (50) for the boom (44), which derricks on an axis (72) parallel to the surface. First driving rollers (110) for the hose (30) are mounted between the ring and the surface, and second ones (106) at the boom, so that there are rollers in front of and behind the two axes (50,72).

Description

Die Erfindung betrifft ein Schlammsaugfahrzeug mit einer Schlauchablage oberhalb des Schlammbehälters, einem Teleskopausleger für einen Saugschlauch, wobei der Teleskopausleger um eine zur Ablageebene der Schlauchablage parallele und zusätzlich dazu vertikale Ebene verschwenkbar ist, sowie mit einer Antriebsrollen aufweisenden Antriebseinheit zum Einfahren des Schlauches auf die bzw. Ausfahren des Schlauches von der Schlauchablage, wobei der Schlauch sich bei seiner Ein- bzw. Ausfahrbewegung auf der Schlauchablage verschiebt.The invention relates to a sludge suction vehicle with a hose rack above the sludge container, a telescopic boom for a suction hose, the telescopic boom being pivotable about a plane parallel to the storage plane of the hose rack and additionally vertical, and with a drive unit having drive rollers for retracting the hose onto or Extending the hose from the hose rest, the hose shifting on the hose rest as it moves in or out.

Ein derartiges Schlammsaugfahrzeug ist ein Abfallentsorgungsfahrzeug, wobei der Abfall aus schlammigen Ablagerungen besteht, die in unterirdischen Abwasserkanälen oder dergleichen sonstigen Kanälen oder Behältern vorhanden sind. Der Abfallbehälter, in den der Saugschlauch einmündet, kann evakuiert werden, so daß der Schlamm durch den Saugschlauch in den Behälter hineingesaugt wird.Such a mud suction vehicle is a waste disposal vehicle, the waste consisting of muddy deposits which are present in underground sewers or the like other channels or containers. The waste container into which the suction hose opens can be evacuated so that the sludge is sucked into the container through the suction hose.

Aus dem deutschen Gebrauchsmuster DE-U-8807777 ist ein derartiges Schlammsaugfahrzeug bekannt. Im vorderen Fahrzeugbereich besitzt der Schlammbehälter einen Dom, auf dem die oberhalb des Schlammbehälters sich erstreckende Schlauchablage außermittig aufgelagert und um eine vertikale Achse schwenkbar gelagert ist. Auf der Schlauchablage ist ferner ein den Saugschlauch führender Teleskopausleger in der Höhe verschwenkbar angelenkt. Der Teleskopausleger ist rohrförmig ausgebildet, wobei der Saugschlauch im Inneren der beiden Rohre geführt ist. Obwohl der Teleskopausleger im Bereich des Domes und damit nahe bei der vertikalen Drehachse für die Schlauchablage an letzterer befestigt ist, ist diese Saugschlauchlager- und Führungskonstruktion durch ihre außermittige Halterung bezüglich der Schwenkachse der Schlauchablage sehr schwingungsanfällig. Beim Verschwenken des Teleskopauslegers in Bereiche seitlich neben dem Schlammsaugfahrzeug muß praktisch längs des gesamten Fahrzeuges ausreichend Freiraum vorhanden sein, da der Teleskopausleger in einem sehr großen Bereich längs des Fahrzeuges jeweils vorhanden ist.Such a mud suction vehicle is known from German utility model DE-U-8807777. In the front area of the vehicle, the sludge container has a dome, on which the hose holder, which extends above the sludge container, is supported off-center and is pivotably mounted about a vertical axis. A telescopic boom guiding the suction hose is also pivoted in height on the hose rack. The telescopic boom is tubular, with the suction hose inside the two Pipes is guided. Although the telescopic boom is attached to the latter in the area of the dome and thus close to the vertical axis of rotation for the hose rest, this suction hose bearing and guide construction is very susceptible to vibration due to its off-center mounting with respect to the pivot axis of the hose rest. When swiveling the telescopic boom into areas to the side of the mud suction vehicle, there must be sufficient free space practically along the entire vehicle, since the telescopic boom is present in a very large area along the vehicle.

Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Schlammsaugfahrzeug der eingangs genannten Art anzugeben, das die aus dem Stand der Technik bekannten Nachteile nicht aufweist und das auch bei eingeengten örtlichen Gegebenheiten optimal eingesetzt werden kann.Starting from this prior art, the invention has for its object to provide a mud suction vehicle of the type mentioned, which does not have the disadvantages known from the prior art and which can be used optimally even in restricted local conditions.

Diese Erfindung ist durch die Merkmale des Hauptanspruchs gegeben. Sie ist bei dem Schlammsaugfahrzeug der eingangs genannten Art dementsprechend dadurch gekennzeichnet, daß die Schlauchablage fest auf dem Schlammbehälter befestigt ist, daß ein Drehkranz außerhalb des von der Schlauchablage überdeckten Fahrzeugbereiches oberhalb des Schlammbehälters vorhanden ist, der um eine zur Ablageebene senkrechte Achse verschwenkbar ist und an dem um eine zur Ablageebene parallele Achse der Teleskopausleger schwenkbar gelagert ist. Ferner sind erste Antriebsrollen im Bereich zwischen dem Drehkranz und der Schlauchablage und zweite Antriebsrollen im Bereich des Teleskopauslegers zum Ein- und Ausfahren des Schlauches vorhanden. Diese Antriebsrollen liegen damit vor und hinter dem Schlauchbereich mit den Orten der Antriebsrollen und damit vor und hinter den Orten der beiden Schwenkachsen. Beim seitlichen Verschwenken des Teleskopauslegers wird durch die ortsfeste Anordnung der Schlauchablage wünschenswert wenig Massen bewegt. Dieser Vorteil wird noch dadurch vergrößert, daß der Teleskopausleger relativ kurz ausgebildet werden kann, da er nicht im vorderen, sondern im hinteren Bereich des Fahrzeuges angeordnet wird. Die im hinteren Bereich des Fahrzeugs vorhandene Lagerung des Teleskopauslegers bedeutet außerdem, daß der beim Verschwenken erforderliche Freiraum nur im Heckbereich des Fahrzeuges und nicht im übrigen Seitenbereich des Fahrzeuges vorhanden zu sein braucht. Durch die örtlich voneinander getrennten Rollenantriebe für den Schlauch wird der beim horizontalen und/oder vertikalen Verschwenken des Teleskopauslegers jeweils abgeknickte Schlauchbereich beidseitig von Antriebsrollen "eingerahmt", wodurch erst diese abgeknickte Schlauchführung ermöglicht wird. Die beiden Rollenantriebe für den Schlauch bewirken außerdem, daß sich der Schlauch in seinem abgeknickten Bereich richtungsgetreu entlang dem jeweils von ihm eingenommenen Bogen beim Ein- und Ausfahren führen läßt und nicht aus diesem seinem jeweiligen Bogen herauswindet oder sonstwie abknickt.This invention is given by the features of the main claim. It is accordingly characterized in the mud suction vehicle of the type mentioned above in that the hose holder is firmly attached to the mud container, that a turntable is present outside the vehicle area covered by the hose holder above the mud container, which is pivotable about an axis perpendicular to the storage plane and on which is pivotally mounted about an axis parallel to the storage plane of the telescopic boom. Furthermore, there are first drive rollers in the area between the slewing ring and the hose holder and second drive rollers in the area of the telescopic boom for extending and retracting the hose. These drive rollers are thus in front of and behind the hose area with the locations of the drive rollers and thus in front of and behind the locations of the two swivel axes. When the telescopic boom is swiveled to the side, the stationary arrangement of the hose rack means that little mass is moved. This advantage is further increased by that the telescopic boom can be made relatively short, since it is not arranged in the front but in the rear area of the vehicle. The storage of the telescopic boom in the rear area of the vehicle also means that the space required for pivoting need only be present in the rear area of the vehicle and not in the remaining side area of the vehicle. Due to the locally separated roller drives for the hose, the hose area that is kinked when the telescopic boom is pivoted horizontally and / or vertically is "framed" by drive rollers on both sides, which only enables this kinked hose guide. The two roller drives for the hose also have the effect that the hose can be guided in its kinked area in the correct direction along the arch it occupies when retracting and extending and does not wind out of its respective arch or otherwise buckle.

Als vorteilhaft hat sich herausgestellt, den Drehkranz bezüglich der Längsachse des Fahrzeuges außermittig im hinteren Fahrzeugbereich anzuordnen. Es kann dann der Ort, an dem der Saugschlauch in den Schlammbehälter einmündet, in dem zum Drehkranz gegenüberliegenden Wandbereich des Fahrzeuges angeordnet werden, wodurch praktisch die gesamte Fahrzeugbreite als Krümmungsbereich für den Schlauch auf der Schlauchablage zur Verfügung steht. Damit ist ein wünschenswert großer Krümmungsradius für den Schlauch auf der Ablage problemlos möglich.It has proven to be advantageous to arrange the turntable off-center in the rear area of the vehicle with respect to the longitudinal axis of the vehicle. The location at which the suction hose opens into the sludge container can then be arranged in the wall region of the vehicle opposite the turntable, whereby practically the entire vehicle width is available as a region of curvature for the hose on the hose holder. This allows a desirable large radius of curvature for the hose on the shelf without any problems.

Um die Reibungsverluste beim Verschieben des Schlauches auf der Schlauchablage möglichst gering zu halten, wodurch das Ein- und Ausfahren des Schlauches lastmäßig erleichtert wird, sind nach einem ganz wesentlichen Merkmal der Erfindung auf der Schlauchablage mehrere walzenförmige Rollenkörper vorhanden, auf denen der Schlauch im Bereich der Ablage aufliegt. Die Achsen dieser Rollenkörper liegen insbesondere in einer Ebene und sind parallel zueinander derart ausgerichtet, daß beim Aus- und Einfahren des Schlauches derselbe auf den Rollen entlangrollt.In order to keep the friction losses when moving the hose on the hose rack as low as possible, which makes it easier to load and retract the hose, several roller-shaped roller bodies are provided on the hose rack according to a very important feature of the invention, on which the hose in the area of Storage rests. The axes of these reel bodies lie, in particular, in one plane and are aligned parallel to one another in such a way that when the hose is extended and retracted, the same is on rolls along the rollers.

Nach einem weiteren Merkmal der Erfindung sind eine erste Kolben-Zylindereinheit zum Verschwenken des Teleskopauslegers vorhanden, deren Zylinder am Drehkranz und deren Kolben an dem Teleskopausleger befestigt sind, und ferner eine zweite Kolben-Zylindereinheit zum Längenverstellen des Teleskopauslegers vorhanden, deren Zylinder an dem nicht verlängerbaren Teleskopteil und deren Kolben an dem in Schlauchrichtung verfahrbaren Teleskopteil befestigt ist.According to a further feature of the invention, there is a first piston-cylinder unit for pivoting the telescopic boom, the cylinders of which are attached to the slewing ring and the pistons of which are attached to the telescopic boom, and there is also a second piston-cylinder unit for adjusting the length of the telescopic boom, the cylinders of which are attached to the non-extendable one Telescopic part and its piston is attached to the telescopic part movable in the hose direction.

Als ausreichend hat es sich ferner herausgestellt, die Teleskopteile so auszubilden, daß sie in Längsrichtung des Schlauches denselben im wesentlichen nur in einem Teilbereich schalen- oder ringförmig umgeben. An dem freien Ende des verfahrbaren Teleskopteils ist dabei insbesondere ein Schlauchführungsbogen befestigt. An diesem Schlauchführungsbogen können Rollen zum Führen des Schlauches befestigt sein.It has also proven to be sufficient to design the telescopic parts in such a way that they surround the tube in the longitudinal direction of the tube essentially only in the form of a shell or ring. In particular, a hose guide bend is attached to the free end of the movable telescopic part. Rollers for guiding the hose can be attached to this hose guide bend.

Aufgrund der erfinderischen Konstruktion ist es möglich, den Drehkranz um etwa 180 bis 220 Grad um seine senkrechte Drehachse verschwenkbar auszubilden und trotzdem noch den relativ dicken Saugschlauch problemlos auf relativ engem Raum entsprechend umzubiegen.Due to the inventive construction, it is possible to design the slewing ring to be pivotable about 180 to 220 degrees about its vertical axis of rotation and still to bend the relatively thick suction hose in a relatively narrow space without any problems.

Weitere Vorteile und Merkmale der Erfindung sind den weiteren Ansprüchen und dem nachstehenden Ausführungsbeispiel zu entnehmen.Further advantages and features of the invention can be found in the further claims and the exemplary embodiment below.

Ein Schlammsaugfahrzeug 10 besitzt hinter seinem Führerhaus 12 einen Schlammbehälter 14, in dem mittels einer Kompressorvorrichtung 16 ein Vakuum erzeugt werden kann.A mud suction vehicle 10 has a mud tank 14 behind its driver's cab 12, in which a vacuum can be generated by means of a compressor device 16.

Im Bereich oberhalb des Führerhauses 12 und des vorderen oberen Bereiches des Schlammbehälters 14 ist eine Schlauchablage 18 vorhanden, die sich in diesem Bereich über praktisch die volle Breite des Schlammsaugfahrzeuges 10 erstreckt. Die Schlauchablage 18 besteht im wesentlichen aus einem umlaufenden Rahmen 20, der durch Queraussteifungen 22 und Längsaussteifungen 24 in etwa gitterförmig ausgebildet ist. In zur Längsachse 26 des Schlammsaugfahrzeuges senkrechter Richtung, d.h. in Querrichtung, sind zwischen den Längsausfachungen 24 walzenförmige Rollen 28 drehbar gelagert. Auf diesen Rollen 28 lagert sich ein Saugschlauch 30 im Bereich der Schlauchablage 18 auf. Das eine Ende dieses Saugschlauches 30 mündet in einen Stutzen 32, der im ― in Fig. 2 unteren ― außermittigen Bereich, außerhalb der Schlauchablage 18, in den Schlammbehälter 14 einmündet.In the area above the driver's cab 12 and the front upper area of the sludge container 14 there is a hose rest 18 which extends in this area over practically the full width of the sludge suction vehicle 10. The hose rest 18 essentially consists of a circumferential frame 20 which is approximately grid-shaped by transverse braces 22 and longitudinal braces 24. In the direction perpendicular to the longitudinal axis 26 of the mud suction vehicle, i.e. in the transverse direction, 24 roller-shaped rollers 28 are rotatably mounted between the longitudinal infills. A suction hose 30 is supported on these rollers 28 in the region of the hose holder 18. One end of this suction hose 30 opens into a connecting piece 32, which opens into the sludge tank 14 in the eccentric region - lower in FIG. 2 - outside the hose holder 18.

Im hinteren Bereich des Fahrzeuges 10, im bezüglich des Stutzens 32 gegenüberliegenden außermittigen Seitenbereich desselben, ist ein Drehkranz 34 oberhalb des Schlammbehälters 14 vorhanden. An diesem Drehkranz ist ein zwei Gabelarme 36, 38 aufweisendes Lager 40 und ein über das Heck 42 des Fahrzeuges 10 hinausragender Teleskopausleger 44 angeschlossen. Die Gabelarme 36, 38 tragen dabei im Bereich ihrer freien Enden jeweils eine um eine vertikale Achse drehbare Rolle 46, 48, die jeweils so ausgelegt sind, daß der Schlauch 30 seitlich an ihnen, zwischen den Gabelarmen 36, 38, geführt werden kann. Die Gabelarme 36, 38 sind fest auf dem Drehkranz 34 befestigt. Beim Verschwenken des Drehkranz 34 um seine vertikale Schwenkachse 50 verschwenkt sich damit auch das Lager 40 in gleicher Weise mit.In the rear area of the vehicle 10, in the eccentric side area thereof opposite the neck 32, there is a slewing ring 34 above the sludge tank 14. A bearing 40 having two fork arms 36, 38 and a telescopic boom 44 projecting beyond the rear 42 of the vehicle 10 are connected to this turntable. The fork arms 36, 38 each carry in the region of their free ends a roller 46, 48 which can be rotated about a vertical axis and are each designed such that the hose 30 is guided laterally on them, between the fork arms 36, 38 can be. The fork arms 36, 38 are fixedly attached to the slewing ring 34. When pivoting the turntable 34 about its vertical pivot axis 50, the bearing 40 also pivots in the same way.

Auch im Bereich des Drehkranz 34 und des Lagers 40 sind den walzenförmigen Rollen 28 in ihrer Funktion entsprechende Rollen 52, 54, 56, vorhanden, auf denen sich der Schlauch 30 auflagern kann. Im Bereich des Lagers 40 sind ferner seitlich an dem Schlauch, sich gegenüberliegend, zwei Rollen 60, 62 vorhanden, zwischen denen der Schlauch 30 entlanggeführt wird.Also in the area of the turntable 34 and the bearing 40 there are rollers 52, 54, 56 in their function corresponding to the roller-shaped rollers 28, on which the hose 30 can be supported. In the area of the bearing 40 there are also two rollers 60, 62 on the side of the hose, opposite one another, between which the hose 30 is guided.

Hinter dem Ort der unteren Rolle 56 und den seitlichen Rollen 60, 62 ― in Richtung des Teleskopauslegers betrachtet ― ist der Teleskopausleger 44 gelenkig an dem Lager 40 und damit an dem Drehkranz 34 angelenkt. Er kann damit um die dort vorhandene Achse 72 in der Höhe verschwenkt werden, was durch den Pfeil 74 angedeutet ist. Diese Schwenkachse 72 ist gleichzeitig Drehachse einer oberen Rolle 75. Am der Achse 72 zugewandten Ende des Teleskopauslegers 44 ist eine untere Rolle 71 an demselben so vorhanden, daß der Saugschlauch immer zwischen diesen Rollen 75, 71 von oben und unter her eingefaßt ist, unabhängig davon, wie der Teleskopausleger höhenmäßig verschwenkt ist; bei Hochschwenken des Teleskopauslegers 44 schwenkt auch die untere Rolle 71 entsprechend mit.Behind the location of the lower roller 56 and the lateral rollers 60, 62 - viewed in the direction of the telescopic boom - the telescopic boom 44 is articulated on the bearing 40 and thus on the slewing ring 34. It can thus be pivoted in height about the axis 72 present there, which is indicated by the arrow 74. This pivot axis 72 is at the same time the axis of rotation of an upper roller 75. At the end of the telescopic boom 44 facing the axis 72 there is a lower roller 71 on the same such that the suction hose is always enclosed between these rollers 75, 71 from above and below, regardless of this how the telescopic boom is pivoted in height; when the telescopic boom 44 is swiveled up, the lower roller 71 also swivels accordingly.

Die Bewegung des Teleskopauslegers 44 nach oben und unten, d.h. in Richtung 74 erfolgt durch seitlich an demselben jeweils vorhandene Zylinder-Kolbeneinheiten. Von jeder dieser beiden Zylinder-Kolbenenheiten ist der Zylinder 78 an dem Lager 40 im Bereich der Drehachse 72 befestigt, während der Kolben 80 an dem nicht ausziehbaren Teleskopteil 82 des Teleskopauslegers 44 befestigt ist. Das Teleskopteil 82 besteht im wesentlichen aus den Schlauch 30 seitlich eingrenzenden Wangen 84, die durch untere Rollenkörper 86 miteinander verbunden sind. Auf diesen Rollenkörpern 86 ruht der Schlauch 30 auf. Die Wangen 84 besitzen jeweils seitliche Führungen 88, die buchsenförmig ausgebildet sind. In diesen Führungen 88 ist in Längsrichtung des Teleskopauslegers eine Führungsstange 90 verschiebbar gelagert. Am vorderen Ende der Führungsstange 90 ist ein Teleskopteil 92 befestigt. Dieses Teleskopteil 92 ist mittels eines Kolbens 94, der innerhalb eines Zylinders 96 in Richtung des Pfeils 98 bewegbar ist, ebenfalls in Richtung 98 hin- und herbewegbar gelagert. An dem Teleskopteil 92 ist ein Führungsbogen 100 für den Schlauch 30 befestigt, der mit Auflagerrollen 102 für den Schlauch 30 versehen ist.The movement of the telescopic boom 44 upwards and downwards, ie in the direction 74, is effected by cylinder-piston units present on the side of the same. Of each of these two cylinder piston units, the cylinder 78 is fastened to the bearing 40 in the region of the axis of rotation 72, while the piston 80 is fastened to the non-extendable telescopic part 82 of the telescopic boom 44. The telescopic part 82 essentially consists of the cheeks 84 which laterally delimit the tube 30 and which are connected to one another by lower roller bodies 86. The hose 30 rests on these reel bodies 86. The cheeks 84 each have lateral guides 88, which are bush-shaped. A guide rod 90 is slidably mounted in these guides 88 in the longitudinal direction of the telescopic boom. A telescopic part 92 is attached to the front end of the guide rod 90. This telescopic part 92 is also mounted so that it can be moved back and forth in the direction 98 by means of a piston 94 which can be moved within a cylinder 96 in the direction of the arrow 98. A guide bend 100 for the hose 30 is attached to the telescopic part 92 and is provided with support rollers 102 for the hose 30.

Im Bereich des nicht ausziehbaren Teleskopteils 82 ist ein Rollenpaar 104, 106 vorhanden, das von unten und oben an dem Saugschlauch 30 anliegt. Diese Rollen 104, 106 werden mittels eines Hydraulikmotors 108 angetrieben, so daß der Saugschlauch 30 ein- und ausgefahren werden kann. Zusätzlich zu diesen Antriebsrollen 104, 106 sind im Bereich zwischen dem Drehkranz 34 und der Schlauchablage 18 ein Block von vier Antriebsrollen 110 vorhanden, die paarweise seitlich an dem Schlauch 30 anliegen und zum Erzielen eines optimalen Anpreßdruckes durch eine nicht näher dargestellte Feinjustiervorrichtung beliebig eng an den Schlauch angelegt werden können. Beim Ein- und Ausfahren des Schlauches 30 werden somit die Antriebrollen 110 und die Antriebsrollen 104, 106 gleichzeitig angetrieben, so daß der Schlauch 30 in Längsrichtung im Bereich seiner horizontalen und/oder vertikalen Abknikkung von Antriebseinrichtungen eingerahmt ist. Der Schlauch kann somit im Bereich zwischen seinen Antriebsrollen 104, 106 und Antriebsrollen 110 nicht ausbeulen oder sonstwie ausknicken. Die seitliche Führung in diesem horizontalen und/oder vertikalen Biegebereich des Schlauches 30 wird noch durch die an den Enden der Gabelarme 36, 38 vorhandenen Rollen 46, 48 unterstützt. Innerhalb des horizontalen Bereiches zwischen diesen Rollen 46, 48 kann sich der Schlauch 30 seitlich beim horizontalen Verschwenken des Teleskopauslegers 44 bewegen.In the area of the telescopic part 82 that cannot be pulled out, a pair of rollers 104, 106 is present, which abuts against the suction hose 30 from below and above. These rollers 104, 106 are driven by a hydraulic motor 108 so that the suction hose 30 can be extended and retracted. In addition to these drive rollers 104, 106, a block of four drive rollers 110 are present in the area between the swivel ring 34 and the hose holder 18, which lie in pairs laterally on the hose 30 and, to achieve an optimal contact pressure, by a fine adjustment device (not shown in more detail) as close as possible to the Hose can be put on. When the hose 30 is extended and retracted, the drive rollers 110 and the drive rollers 104, 106 are thus driven simultaneously, so that the hose 30 is framed by drive devices in the longitudinal direction in the region of its horizontal and / or vertical bend. The hose can therefore not bulge or buckle in the area between its drive rollers 104, 106 and drive rollers 110. The lateral guidance in this horizontal and / or vertical bending region of the hose 30 is further supported by the rollers 46, 48 provided at the ends of the fork arms 36, 38. Within the horizontal area between these rollers 46, 48, the hose 30 can move laterally when the telescopic boom 44 is pivoted horizontally.

Sofern der Saugschlauch 30 mehr oder weniger geringfügig von dem jeweiligen Saugbereich weggezogen werden soll, müssen nicht die Antriebsrollen 104, 106 und 110 angetrieben und dadurch der Saugschlauch ein wenig eingefahren werden, sondern es kann dazu der Teleskopausleger 44 entsprechend weit angehoben werden. Der Saugschlauch 30 bewegt sich damit nicht relativ zu seinen Antriebsrollen, so daß ein durch das Antreiben der Antriebsrollen bedingter Verschleiß der Oberfläche des Saugschlauches vermieden werden kann. Ein in seiner Saugstellung in einem Abwasserkanal oder dergleichen festsitzender Saugschlauch kann also lediglich durch nach oben und unten wippenden Bewegung des Teleskopauslegers in dem Abwasserkananl bewegt werden. Es hat sich nämlich gezeigt, daß eine derartige Bewegungsführung eines Saugschlauches sehr häufig während eines Absaugvorganges vorkommt und daß die dadurch bewirkte Abnutzung des Saugschlauches entsprechend intensiv ist.If the suction hose 30 is to be pulled more or less slightly away from the respective suction area, the drive rollers 104, 106 and 110 do not have to be driven and the suction hose thus have to be retracted a little, but the telescopic boom 44 can be raised correspondingly far for this purpose. The suction hose 30 thus does not move relative to its drive rollers, so that wear on the surface of the suction hose caused by the drive rollers can be avoided. A suction hose which is stuck in its suction position in a sewer or the like can therefore only be moved in the sewer duct by the upward and downward movement of the telescopic boom. It has been shown that such a movement of a suction hose occurs very frequently during a suction process and that the wear of the suction hose caused thereby is correspondingly intense.

Die für den Antrieb der Rollen 104, 106, 110 erforderliche motorische Leistung kann relativ klein ausgelegt werden, da der Schlauch bei seinem Verschieben auf der Schlauchablage 18 sich über die Rollen 28 hinwegbewegt und infolgedessen die beim Verschieben ansonsten auftretenden Reibungskräfte zwischen dem Schlauch und der Schlauchablageoberfläche extrem klein sind.The motor power required to drive the rollers 104, 106, 110 can be designed to be relatively small since the tube moves over the rollers 28 when it is moved on the tube holder 18 and consequently the frictional forces that otherwise occur during the displacement between the tube and the tube holder surface are extremely small.
