Abstract

The truck for cleaning street drains has a telescopic suction hose (3) linked to a tank (2), and supported by a telescopic jib (7) for its deployment. The jib has a base carrier (9) for an extending carrier (10) as a number of linked sections (10a-10c). As the carrier is extended, its links are moved by a limit stop in a curved path to bring the suction hose from the horizontal into a vertical downwards alignment to be inserted into the drain.

Description

Die Erfindung betrifft ein Reinigungsfahrzeug, insbesondere für Kanalreinigung, Straßenreinigung, Sinkkastenreinigung und dergleichen, mit einem mit Saugzug beaufschlagbaren Saugschlauch, einer dem Saugschlauch zugeordneten Speichereinrichtung, aus der der Saugschlauch bis zum Erreichen gewünschten Länge ausfahrbar ist und umgekehrt, und einem den speichernahen Saugschlauchabschnitt aufnehmenden Ausleger, der als Teleskopausleger ausgebildet ist, der einen Grundträger und einen aus diesem aus bzw. in diesen einfahrbaren Verlängerungsträger aufweist, durch dessen Endbereich der Saugschlauch im Bogen nach unten umlenkbar ist.The invention relates to a cleaning vehicle, in particular for sewer cleaning, street cleaning, gully and the like, with a suction hose can be acted upon with suction, a suction hose associated storage device from which the suction hose is extendable to reach the desired length and vice versa, and a storage near suction hose section receiving boom , which is designed as a telescopic boom, which has a base support and a retractable from this or in this extension support, through the end region of the suction hose in the bow is deflected downwards.

Ein Reinigungsfahrzeug dieser Art ist aus der EP 068 32 78 A2 bekannt. Bei diesem bekannten Reinigungsfahrzeug besitzt der Verlängerungsträger ein starres, rüsselartig nach unten gebogenes Endstück, das aus fest miteinander verschweissten Teilstücken besteht. Hierdurch wird zwar eine sanfte, knickfreie Umlenkung des Saugschlauchs erreicht. Es ist aber nicht möglich, den Verlängerungsträger ganz in den Grundträger einzufahren. Es kann daher zu Behinderungen im fahrbereiten Zustand kommen. Sofern der Ausleger über das Fahrerhaus hinauskragt, was bei manchen Kanalreinigungsfahrzeugen vorgesehen ist, um den Ablauf des Saugschlauches vom Fahrerhaus beobachten zu können, befindet sich das Endstück des Auslegers im fahrbereiten Zustand im Sichtbereich der Windschutzscheibe, was zu einer Sichtbehinderung und damit zu einer Beeinträchtigung der Verkehrssicherheit führen kann. Sofern der Ausleger nach hinten auskragt, ergibt sich eine vom Fahrerhaus aus schlecht einsehbare, rückwärtige Verlängerung des Fahrzeugs, was ebenfalls unerwünscht ist.A cleaning vehicle of this type is known from EP 068 32 78 A2. In this known cleaning vehicle, the extension carrier has a rigid, trunk-like downwardly bent tail, which consists of tightly welded together sections. As a result, although a gentle, kink-free deflection of the suction hose is achieved. However, it is not possible to retract the extension carrier completely into the basic carrier. It can therefore come to disabilities in running order. If the boom overhangs the cab, which is provided in some sewer cleaning vehicles to observe the expiry of the suction hose from the cab, the tail of the boom is in running order in the field of vision of the windshield, resulting in a visual obstruction and thus to an impairment of Traffic safety can lead. If the boom protrudes to the rear, there is a From the cab from poorly visible, rearward extension of the vehicle, which is also undesirable.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, ein Reinigungsfahrzeug eingangs erwähnter Art unter Beibehaltung seiner Vorteile und Vermeidung seiner Nachteile mit einfachen und kostengünstigen Mitteln so zu verbessern, dass der Verlängerungsträger ganz in den Grundträger eingefahren werden kann.On this basis, it is therefore an object of the present invention to improve a cleaning vehicle of the type mentioned while maintaining its advantages and avoiding its disadvantages with simple and inexpensive means so that the extension support can be moved completely into the base support.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Verlängerungsträger mehrere, gelenkig miteinander verbundene, bis auf Anschlag gegeneinander abknickbare Teilstücke aufweist, die beim Ausfahren aus dem Grundträger bis auf Anschlag nach unten gegeneinander abknickbar und beim Einfahren in den Grundträger in die Streckstellung bringbar sind.This object is achieved in that the extension carrier has a plurality of hingedly interconnected, abutment against each other abknickbare sections, which are abzubickbar upon extension from the base support down to the stop down against each other and when retracted into the base support in the extended position can be brought.

Die gelenkig miteinander verbundenen, bis auf Anschlag gegeneinander abknickbaren Teilstücke des Verlängerungsträgers bilden im ausgefahrenen Zustand ein bogenförmig nach unten verlaufendes Endstück, das den Saugschlauch sanft nach unten umlenkt, so dass ein vorgeschriebener Biegeradius eingehalten werden kann. Ebenso ist eine Beobachtung des Ablaufs des Saugschlauches vom Fahrerhaus aus möglich, so dass der Fahrer den Saugschlauch beim Manipulieren in seinem direkten Blickfeld hat, ohne aus dem Fahrerhaus aussteigen zu müssen. In Folge der Streckbarkeit der Teilstücke des Verlängerungsträgers kann dieser nach Beendigung der Reinigungsarbeiten praktisch vollständig in den Grundträger eingefahren werden, so dass der nach unten verlaufende Bogen verschwindet und daher im fahrbereiten Zustand keinerlei Sichtbehinderungen zu befürchten sind, was sich vorteilhaft auf die Verkehrssicherheit auswirkt. Die gelenkig miteinander verbundenen Teilstücke gehen beim Ausfahren aus dem Grundträger aufgrund ihres Gewichts bzw. des auf ihnen lastenden Schlauchgewichts automatisch in die Knickstellung und werden beim Einfahren in den Grundträger praktisch automatisch in die Streckstellung zurückgeschwenkt. Ein hierfür erforderlicher Schwenkantrieb ist daher in vorteilhafter Weise nicht erforderlich.The articulated interconnected, abut against each other abknickbaren sections of the extension support in the extended state form an arcuate downwardly extending tail, which deflects the suction hose gently downwards, so that a prescribed bending radius can be met. Similarly, an observation of the flow of the suction hose from the cab is possible, so that the driver has the suction hose when manipulating in his direct field of view, without having to get out of the cab. As a result of the stretchability of the sections of the extension support of this can be almost completely retracted after completion of the cleaning work in the base support, so that the down running arc disappears and therefore no visibility obstructions are to be feared in the ready to drive condition, which has an advantageous effect on traffic safety. The hingedly interconnected sections go automatically when moving out of the base support due to their weight or the weight on them weight hose in the bent position and are practically automatically swung back into the extended position when retracted into the base support. A pivot drive required for this purpose is therefore not required in an advantageous manner.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. So können zumindest ein Teil der Teilstücke nach Art der Seitenflanken von Gewölbesteinen gegeneinander abgeschrägte Stirnseiten aufweisen. Diese bilden dabei die die Knickbewegung begrenzenden Anschläge. Eine derartige Ausbildung erweist sich daher als besonders einfach und zuverlässig. Zweckmäßig ist dabei die Gelenkverbindung im Bereich der gegenüber der Unterseite längeren Oberseite der Teilstücke angeordnet. Hierdurch ergeben sich besonders große Anschlagflächen.Advantageous embodiments and expedient developments of the higher-level measures are specified in the subclaims. Thus, at least some of the sections may have, in the manner of the side flanks of arched stones, end faces which are bevelled relative to one another. These form the stops limiting the bending movement. Such training therefore proves to be particularly simple and reliable. Suitably, the hinge connection is arranged in the region of the upper side of the sections which is longer relative to the underside. This results in particularly large stop surfaces.

In weiterer Fortbildung der übergeordneten Maßnahmen ist vorgesehen, dass die Gelenkverbindung unterhalb der Oberkante des Verlängerungsträgers angeordnet ist. Dies ermöglicht in vorteilhafter Weise eine Anpassung der Querschnittsaußenkonfiguration der Teilstücke des Verlängerungsträgers an den lichten Innenquerschnitt des Grundträgers, wodurch sich eine einfache und zuverlässige Führung ergibt.In a further development of the higher-level measures, it is provided that the articulated connection is arranged below the upper edge of the extension carrier. This advantageously allows an adaptation of the cross-sectional outer configuration of the sections of the extension support to the clear inner cross section of the base support, resulting in a simple and reliable guidance.

Vorteilhaft kann am vorderen Ende des letzten Endstücks des Verlängerungsträgers eine vom Saugschlauch durchgriffene Öse vorgesehen sein. Hierbei handelt es sich um ein einfaches und zuverlässiges, dem Saugschlauch zugeordnetes Führungsmittel, das ein genaues Manipulieren des freien Saugschlauchendes mittels des Auslegers erleichtert.Advantageously, at the front end of the last end piece of the extension support, an eyelet penetrated by the suction hose can be provided. This is a simple and reliable, the suction hose associated guide means that facilitates accurate manipulation of the free end of the suction hose by means of the boom.

Eine weitere zweckmäßige Fortbildung der übergeordneten Maßnahmen kann darin bestehen, dass im Bereich des vorderen Endes des Grundträgers eine den Teilstücken des Verlängerungsträgers zugeordnete Leiteinrichtung, vorzugsweise in Form einer Anlauframpe, vorgesehen ist. Diese Maßnahme ergibt praktisch eine Kurvensteuerung, die eine zuverlässige und schonende Schwenkbewegung der ab- und aufkippbaren Teilstücke des Verlängerungsträgers gewährleistet.A further expedient development of the higher-level measures may consist in that in the region of the front end of the basic carrier, a guide device associated with the sections of the extension carrier, preferably in the form of a start-up ramp, is provided. This measure practically results in a curve control, which ensures a reliable and gentle pivotal movement of the tilting and aufkippbaren sections of the extension support.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung näher entnehmbar.Further advantageous embodiments and expedient developments of the parent measures are specified in the remaining subclaims and from the following description of an embodiment with reference to the drawing closer.

Das Anwendungsgebiet der Erfindung erstreckt sich auf Reinigungsfahrzeuge aller Art, die mit einem mit Saugzug beaufschlagbaren, über einen Ausleger geführten Saugschlauch arbeiten, wie das bei Kanalreinigungsfahrzeugen, Straßenreinigungsfahrzeugen, Sinkkastenreinigungsfahrzeugen und dergleichen der Fall ist. Der grundsätzliche Aufbau und die Wirkungsweise derartiger Fahrzeuge sind an sich bekannt und bedürfen daher im vorliegenden Zusammenhang keiner näheren Erläuterung mehr.The field of application of the invention extends to cleaning vehicles of all kinds, which operate with a suction train acted upon, guided over a boom suction hose, as is the case with sewer cleaning vehicles, road cleaning vehicles, gully cleaning vehicles and the like. The basic structure and operation of such vehicles are known per se and therefore need no further explanation in the present context.

Das den Figuren 1 und 2 zugrundeliegende Reinigungsfahrzeug dient beispielsweise zur Sinkkastenreinigung. Dieses Fahrzeug enthält einen auf der Fahrzeugchassis aufgenommenen Schmutzaufnahmebehälter 1. Auf diesem ist eine mit stehender Achse angeordnete Haspel 2 montiert, auf der ein Saugschlauch 3 mit liegenden Windungen aufnehmbar ist. Das nicht sichtbare, haspelseitige Ende des Saugschlauchs 3 kann in nicht näher dargestellter Weise über eine Drehverbindung mit einem die Haspellagerung durchgreifenden, in den Schlammaufnahmebehälter 1 einmündenden Einwurfstutzen verbunden sein. Die Haspel 2 ist mittels einer zugeordneten Antriebseinrichtung in beiden Richtungen antreibbar, so dass der Saugschlauch 3 von der praktisch einen Saugschlauchspeicher bildenden Haspel 2 bis zum Erreichen der gewünschten Länge abwickelbar bzw. auf diese aufwickelbar ist.The Figures 1 and 2 underlying cleaning vehicle is used, for example, Sinkkastenreinigung. This vehicle includes a recorded on the vehicle chassis dirt receptacle 1. On this one arranged with a stationary axis reel 2 is mounted, on which a suction hose 3 with lying turns is receivable. The invisible, reel-side end of the suction hose 3 can in a manner not shown via a rotary joint with a the Hasp storage thorough, be in the mud receptacle 1 merging Einwurfstutzen be connected. The reel 2 can be driven in both directions by means of an associated drive device, so that the suction hose 3 can be unwound from the reel 2 that practically forms a suction hose accumulator until it reaches the desired length or can be wound onto it.

An der Vorderwand des Schlammaufnahmebehälters 1 ist hier eine Konsole 4 angebracht, auf der ein um eine stehende Achse drehbarer Lagerbock 5 aufgenommen ist, der einen über das Fahrerhaus 6 nach vorne auskragenden Ausleger 7 zur Aufnahme des der Haspel 2 benachbarten Bereichs des Saugschlauchs 3 trägt. Zur Drehung des Lagerbocks 5 samt Ausleger 7 um die stehende Achse ist eine geeignete Antriebseinrichtung vorgesehen. Der Lagerbock 5 ist zweckmäßig so positioniert, dass der Saugschlauch 3 im Wesentlichen niveaugleich von der Haspel 2 ab- und auf das hintere Ende des Auslegers 7 auflaufen kann und umgekehrt. Der Ausleger 7 kann auf dem Lagerbock 5 um eine liegende Achse schwenkbar aufgenommen und mittels einer Hubeinrichtung schwenkbar sein. In der dargestellten Grundstellung steigt der Ausleger 7 vom Lagerbock 5 ausgehend leicht nach vorne an.On the front wall of the sludge receiving container 1 here a console 4 is mounted, on which a rotatable about a stationary axis bearing block 5 is received, which carries a projecting over the cab 6 forward boom 7 for receiving the reel 2 adjacent portion of the suction hose 3. For rotation of the bearing block 5 together with boom 7 about the vertical axis a suitable drive means is provided. The bearing block 5 is expediently positioned so that the suction hose 3 can essentially level off the reel 2 at the same level and run onto the rear end of the jib 7, and vice versa. The boom 7 can be pivotally received on the bearing block 5 about a horizontal axis and be pivotable by means of a lifting device. In the illustrated basic position, the boom 7 rises from the bearing block 5, starting slightly forward.

Durch den Ausleger 7 wird der Saugschlauch 3, wie Figur 1 anschaulich zeigt, über das Fahrerhaus 6 hinweggeführt. Das vordere Ende des Auslegers 7 ist nach unten gebogen, so dass der Saugschlauch 3 hierdurch nach unten umgelenkt wird. Das vordere Ende des Saugschlauchs 3 kann dementsprechend in einen vom Fahrerhaus 6 aus sichtbaren Sinkkasten 8 eingeführt werden. Hierzu wird der Saugschlauch 3 mittels des Auslegers 7, das heißt durch entsprechende Bewegungen des Auslegers 7 entsprechend manipuliert und bis zur gewünschten Länge von der Haspel 2 abgewickelt.By the boom 7, the suction hose 3, as Figure 1 shows clearly, passed over the cab 6. The front end of the boom 7 is bent down, so that the suction hose 3 is thereby deflected downwards. Accordingly, the front end of the suction hose 3 can be inserted in a sink box 8 visible from the driver's cab 6. For this purpose, the suction hose 3 by means of the boom 7, that is manipulated by appropriate movements of the boom 7 and unwound to the desired length of the reel 2.

Der Ausleger 7 ist als Teleskopausleger ausgebildet, der einen auf dem Lagerbock 5 aufgenommenen Grundträger 9 und einen aus diesem ausfahrbaren Verlängerungsträger aufweist, der aus mehreren, aneinander anschließenden Teilstücken 10a, b, c besteht. In der der Figur 1 zugrundeliegenden Arbeitsstellung ist der im Folgenden als ganzes mit 10 bezeichnete Verlängerungsträger bis zu einer maximalen Ausfahrlänge aus dem Grundträger 9 ausgefahren. In der der Figur 2 zugrundeliegenden, fahrbereiten Stellung ist der Verlängerungsträger 10 in den Grundträger 9 eingefahren.The boom 7 is designed as a telescopic boom, which has a base support 9 received on the bearing block 5 and an extension support which can be extended therefrom and which consists of a plurality of adjoining parts 10a, b, c. In the working position on which FIG. 1 is based, the extension carrier referred to below as a whole with 10 is extended out of the base carrier 9 up to a maximum extension length. In the figure 2 underlying, ready to drive position, the extension carrier 10 is retracted into the base support 9.

In der der Figur 1 zugrundeliegenden Arbeitsstellung sind die Teilstücke 10a, b, c des Verlängerungsträgers 10 so gegeneinander abgeknickt, dass sich ein nach unten gerichteter Rüssel ergibt, durch den der auf dem Ausleger 7 aufgenommene Saugschlauch 3 im Bogen nach unten geführt wird, wodurch eine Knickung des Saugschlauches 3 vermieden wird. Im dargestellten Beispiel besteht der Verlängerungsträger 10 aus drei Teilstücken 10a, b, c, die in der Arbeitsstellung nach Art von Gewölbesteinen aneinander anschließen, wie Figur 1 anschaulich erkennen lässt. Das rückwärtige Teilstück 10a ist auch in der Arbeitsstellung mit seinem hinteren Endbereich im Eingriff mit dem Grundträger 9 und verläuft dementsprechend koaxial hierzu. Das mittlere Teilstück 10b und das vordere Teilstück 10c sind jeweils gegenüber dem benachbarten Teilstück um einen Winkel nach unten abgeknickt.In the working position underlying the figure 1, the sections 10 a, b, c of the extension support 10 are bent against each other so that there is a downwardly directed trunk through which the suction hose 3 received on the boom 7 is guided in the arc down, creating a Buckling of the suction hose 3 is avoided. In the example shown, the extension beam 10 consists of three sections 10a, b, c, which connect in the working position in the manner of vault stones to each other, as Figure 1 shows clearly. The rear portion 10a is in the working position with its rear end portion in engagement with the base support 9 and accordingly runs coaxially thereto. The middle section 10b and the front section 10c are each bent downwards relative to the adjacent section by an angle.

Hierzu sind das mittlere und das vordere Teilstück 10b, c im Bereich ihrer Oberkante länger als im Bereich ihrer Unterkante, so dass sich wie bei einem Gewölbestein v-förmig gegeneinander geneigte Stirnseiten ergeben. Das rückwärtige Teilstück 10a ist im dargestellten Beispiel mit achsnormalen Stirnseiten versehen. Es wäre aber auch denkbar, die dem mittleren Teilstück 10b zugewandte Stirnseite des rückwärtigen Teilstücks 10a entsprechend zu neigen. In der eingefahrenen Stellung gemäß Figur 2 befinden sich die Teilstücke 10a, b, c in einer zum Grundträger 9 koaxialen Streckstellung, wobei die gegeneinander geneigten Stirnseiten, wie in Figur 2 angedeutet ist, einen nach unten sich erweiternden Spalt 11 begrenzen, der zwischen dem hinteren und dem mittleren Teilstück 1a, b kleiner als zwischen dem mittleren und dem vorderen Teilstück 10b, c ist, so dass sich ein sanft nach unten verlaufender Bogen ergibt.For this purpose, the middle and the front portion 10b, c in the region of its upper edge are longer than in the region of its lower edge, so that arise as in a vaulted stone v-shaped mutually inclined end faces. The rear portion 10a is provided in the example shown with achsnormalen end faces. It would also be conceivable, however, to incline the end face of the rear section 10a facing the middle section 10b accordingly. In the retracted position according to FIG. 2, the sections 10a, b, c are in an extended position coaxial with the base carrier 9, wherein the mutually inclined end sides, as indicated in FIG. 2, delimit a downwardly widening gap 11, which is between the rear and the central portion 1a, b is smaller than between the middle and front portions 10b, c, so as to give a gently downward arc.

Zur Führung des auf dem Ausleger 7 aufgenommenen Saugschlauchs 3 ist am vorderen Ende des vorderen Endstücks 10c eine nach oben abstehende Öse 12 angebracht, durch die der Saugschlauch 3 hindurchgreift. Weitere, dem Saugschlauch 3 zugeordnete Führungsmittel sind bei dem den Figuren 1 und 2 zugrundeliegenden Beispiel im Bereich des Grundträgers 9 vorgesehen. Im dargestellten Beispiel sind hierzu den auf der Oberseite des Auslegers 7 laufenden Saugschlauch 3 beidseitig flankierende, vom Grundträger 9 nach oben ragende Leitrollen 13 vorgesehen. Diese können mittels einer zugeordneten Antriebseinrichtung anteibbar sein, um den Haspelantrieb zu entlasten. Im dargestellten Beispiel sind die Leitrollen 13 lediglich frei drehbar, was im Normalfall auch genügt.For guiding the suction hose 3 accommodated on the boom 7, an upwardly projecting eyelet 12 is attached at the front end of the front end piece 10c through which the suction hose 3 passes. Further, the suction hose 3 associated guide means are provided in the Figures 1 and 2 underlying example in the region of the base support 9. In the example shown, the suction hose 3 running on the upper side of the jib 7 is provided with flanking guide rollers 13 projecting upwards on both sides from the base support 9. These can be anteibbar by means of an associated drive means to relieve the reel drive. In the example shown, the guide rollers 13 are only freely rotatable, which also normally suffices.

Ähnliche, den Saugschlauch 3 flankierende Leitrollen 13 können auch den Teilstücken 10a, b, c des Verlängerungsträgers 10 zugeordnet sein, wie die Figuren 3 und 4 für das Teilstück 10b zeigen. Um einen störungsfreien Einlauf des mit Leitrollen 13 versehenen Teilstücks 10b in den Grundträger 9 zu gewährleisten, sind die Leitrollen 13 hier auf den seitlichen Schenkeln eines T-förmigen Bügels 14 aufgenommen, der mit seinem Steg auf der Oberseite des zugeordneten Teilstücks angebracht ist. Der Grundträger 9 ist, wie Figur 4 anschaulich zeigt, im Bereich seiner Oberseite mit einem dem Steg des Bügels 14 zugeordneten Schlitz 15 versehen, in den der Steg des Bügels 14 beim Einfahren des Verlängerungsträgers 10 in den Grundträger 9 einlaufen kann. Die Höhe des Stegs des Bügels 14 ist so bemessen, dass die seitlich auskragenden, die Leitrollen 13 aufnehmenden Schenkel im eingefahrenen Zustand, wie aus Figur 4 erkennbar ist, den Grundträger 9 mit ausreichendem Laufspiel übergreifen. Auch die dem Verlängerungsträger 10 zugeordneten Leitrollen 13 können, wie oben für die Leitrollen 13 des Grundträgers 9 bereits erwähnt wurde, antreibbar sein. Im dargestellten Beispiel sind sie als frei drehbar gelagerte Rollen ausgebildet.Similar guide rollers 13 flanking the suction hose 3 may also be associated with the sections 10a, b, c of the extension carrier 10, as shown in FIGS. 3 and 4 for the section 10b. In order to ensure a trouble-free inlet of the provided with guide rollers 13 portion 10b in the base support 9, the guide rollers 13 are here taken on the lateral legs of a T-shaped bracket 14 which is mounted with its web on top of the associated portion. The base support 9 is, as Figure 4 clearly shows, provided in the region of its upper side with a web of the bracket 14 associated slot 15 into which the web of the bracket 14 when retracting the extension member 10 can enter into the base support 9. The height of the web of the bracket 14 is dimensioned so that the laterally projecting, the guide rollers 13 receiving leg in the retracted state, as can be seen from Figure 4, the base support 9 overlap with sufficient clearance. Also, the extension carrier 10 associated guide rollers 13, as already mentioned above for the guide rollers 13 of the base support 9, be driven. In the example shown, they are designed as freely rotatably mounted rollers.

Anstelle von drehbaren Leitrollen könnten in einfachen Fällen auch starre Stifte vorgesehen sein. Ebenso wäre es denkbar, anstelle von den Saugschlauch 3 flankierenden Führungscinrichtungen auch nach oben geschlossene Führungseinrichtungen, etwa derselben Form wie die Öse 12, vorzusehen. Ebenso wäre es denkbar, im Bereich der Oberseite des Grundträgers 9 und/oder des Verlängerungsträgers 10 die Unterseite des Saugschlauchs 3 aufnehmende Laufrollen vorzusehen.Instead of rotating guide rollers and rigid pins could be provided in simple cases. It would also be conceivable, instead of the suction hose 3 flanking Führungscinrichtungen also upwardly closed guide means, approximately the same shape as the eyelet 12 to provide. It would also be conceivable to provide the underside of the suction hose 3 receiving rollers in the region of the upper side of the base support 9 and / or of the extension support 10.

Die Teilstücke 10a, b, c sind, wie in Figur für die Teilstücke 10a, b beispielhaft dargestellt ist, im Bereich ihrer Oberkante durch ein eine horizontale Achse aufweisendes Gelenk 16 miteinander verbunden. Die Gelenke 16 sind zweckmäßig so ausgebildet, dass sie nicht über die Oberkante vorstehen und daher ein Einfahren des Verlängerungsträgers 10 in den Grundträger 9 nicht behindern. Sofern bezüglich der lichten Höhe des Grundträgers 9 genügend Spiel vorgesehen ist, können auf den Gelenkachsen drehbar gelagerte, im Rahmen des genannten Spiels nach oben verstehende Laufrollen vorgesehen sein, die ein Ablaufen des Saugschlauchs 3 erleichtern.The sections 10a, b, c are, as shown by way of example for the sections 10a, b, in the region of their upper edge connected by a hinge 16 having a horizontal axis. The joints 16 are expediently designed such that they do not protrude beyond the upper edge and therefore do not hinder retraction of the extension carrier 10 into the base support 9. Insofar as sufficient play is provided with respect to the clear height of the base support 9, rollers which are rotatably mounted on the hinge axes and can be seen upwardly within the scope of said play can be provided, which facilitate drainage of the suction hose 3.

Im Bereich des vorderen Endes des Grundträgers 9 ist eine gegenüber der Unterkante des Einlaufquerschnitts des Grundträgers 9 nach vorne vorspringende Anlauframpe 17 vorgesehen, an der die nach unten abgeknickten Tragstücke 10b, 10c beim Einfahren des Verlängerungsträgers 10 in den Grundträger 9 mit ihrer rückwärtigen Unterkante anlaufen. Die Anlauframpe 17 bildet dabei praktisch eine Führungsfläche, durch welche die nach unten geknickten Teilstücke 10b, c beim Einfahren des Verlängerungsträgers 10 in den Grundträger 9 langsam und geordnet von der geknickten Stellung in die Streckstellung gebracht werden, wodurch die zum Einfahren des Verlängerungsträgers 10 benötigten Kräfte vergleichsweise klein bleiben. Beim Ausfahren des Verlängerungsträgers 10 aus dem Grundträger 9 bewirkt die genannte Führungsfläche ein langsames und geordnetes Absenken der vorderen Teilstücke 10c, b von der Streckstellung in die abgeknickte Position, wodurch ein ruckartiges Abkippen unterbleibt. Anstelle einer Anlauframpe könnte selbstverständlich auch eine Rollenanordnung mit einer oder mehreren Rollen vorgesehen sein. In einfachen Fällen genügt es, einfach die Unterkante der vorderen Stirnseite des Grundträgers 9 abzurunden oder abzuschrägen.In the region of the front end of the base support 9, a starting ramp 17 protruding forwardly with respect to the lower edge of the inlet cross section of the base support 9 is provided, at which the downwardly bent support pieces 10b, 10c start when the extension support 10 retracts into the base support 9 with its rear lower edge. The start-up ramp 17 practically forms a guide surface through which the downwardly bent portions 10b, c are brought slowly and in an orderly manner from the bent position into the extended position when retracting the extension carrier 10 into the base support 9, whereby the forces required for retracting the extension support 10 are obtained stay relatively small. When extending the extension support 10 from the base support 9 causes said guide surface a slow and orderly lowering the front portions 10c, b from the extended position in the bent position, whereby a jerky tilting is omitted. Of course, instead of a start-up ramp, a roller arrangement with one or more rollers could also be provided. In simple cases it is sufficient to simply round off or bevel the lower edge of the front end face of the base support 9.

Zur Begrenzung der Abkippbewegung können Anschläge vorgesehen sein. Im dargestellten Beispiel wird die Abkippbewegung dadurch begrenzt, dass die einander zugewandten Stirnseiten der Teilstücke 10a, b, c in gegenseitige Anlage kommen. Hier fungieren dementsprechend die einander zugewandten Stirnseiten der Teilstücke 10a, b, c als Anschläge, was große Anschlagflächen und damit vergleichsweise geringe Flächenpressungen ergibt. Die Hochschwenkbewegung kann ebenfalls durch Anschläge, die in der Streckstellung in gegenseitige Anlage kommen, begrenzt sein. In der Regel ist dies jedoch nicht erforderlich, da bereits der Grundträger 9, in den die Verlängerungsstücke 10a, b, c eingefahren werden, als derartiger Anschlag fungiert, der ein über die Streckstellung hinausgehendes Hochkippen der Teilstücke 10b, c verhindert.To limit the Abkippbewegung attacks can be provided. In the example shown, the tilting movement is limited by the fact that the facing end faces of the sections 10a, b, c come into mutual contact. Correspondingly, the mutually facing end faces of the sections 10 a, b, c act as stops, which results in large stop surfaces and thus comparatively low surface pressures. The Hochschwenkbewegung can also be limited by stops that come in the extended position in mutual contact. In general, however, this is not necessary, since even the base support 9, in which the extension pieces 10a, b, c are retracted, acts as such a stop, which prevents over the extended position tipping up of the portions 10b, c.

Zum Ein- und Ausfahren des Verlängerungsträgers 10 ist eine Antriebseinrichtung vorgesehen. Bei dem der Figur 5 zugrundeliegenden Beispiel handelt es sich dabei um einen Hubzylinder 18, der mit seinem hinteren Ende am hinteren Endbereich des Grundträgers 9 und mit seinem vorderen Ende am vorderen Endbereich des rückwärtigen Teilstücks 10a, das nicht vollständig aus dem Grundträger 9 ausgefahren wird, angelenkt ist. Im dargestellten Beispiel ist der Hubzylinder 18 als einteiliger Hubzylinder ausgebildet, dessen Hub dem Aus- bzw. Einfahrhub entspricht. Selbstverständlich könnte aber auch ein mehrteiliges Aggregat vorgesehen sein. Der Hubzylinder 18 ist zweckmäßig als doppelt wirkendes Aggregat ausgebildet, das Kräfte in beiden Richtungen erzeugen kann, so dass eine zuverlässige Ausfahr- und Einfahrbewegung gewährleistet ist. Der Hubzylinder 18 ist dabei vorteilhaft mit dem Antrieb der Saugschlauchhaspel 2 so synchronisiert, dass sich gleichförmige Bewegungen des Saugschlauchs 3 sowie des Verlängerungsträgers 10 ergeben. Dasselbe gilt natürlich für die Antriebe der Leitrollen bzw. Laufrollen, sofern diese angetrieben sein sollten.For extending and retracting the extension carrier 10, a drive device is provided. 5 is an elevating cylinder 18 with its rear end at the rear end portion of the base support 9 and with its front end at the front end portion of the rear portion 10a, which is not fully extended from the base support 9, is articulated. In the example shown, the lifting cylinder 18 is formed as a one-piece lifting cylinder whose stroke corresponds to the training and retraction. Of course, but could also be provided a multi-part unit. The lifting cylinder 18 is suitably designed as a double-acting unit that can generate forces in both directions, so that a reliable extension and Retraction is guaranteed. The lifting cylinder 18 is advantageously synchronized with the drive of the Saugschlauchhaspel 2 so that uniform movements of the suction hose 3 and the extension carrier 10 result. The same naturally applies to the drives of the guide rollers or rollers, if they should be driven.

Der Grundträger 9 ist, wie die Figuren 3 bis 5 erkennen lassen, zweckmäßig als Kastenträger mit einem rechteckförmigen Querschnitt ausgebildet. Die Außenkonfiguration des Querschnitts der Teilstücke 10a, b, c des Verlängerungsträgers entspricht praktisch dem lichten Querschnitt des Grundträgers 9 abzüglich eines oben bereits erwähnten Laufspiels. Der den Grundträger 9 bildende Kastenträger bildet automatisch eine allseits geschlossene Führungsbahn für die Teilstücke 10a, b, c des Verlängerungsträgers. Selbstverständlich können innerhalb des Grundträgers 9 noch die Führung für den Verlängerungsträger 10 bildende Führungsmittel vorgesehen sein, wie in Figur 5 durch Gleitschienen 19 angedeutet ist.The base support 9 is, as can be seen from FIGS. 3 to 5, expediently designed as a box girder with a rectangular cross-section. The outer configuration of the cross section of the sections 10a, b, c of the extension carrier corresponds in practice to the clear cross section of the base carrier 9 minus a running clearance already mentioned above. The box girder forming the base girder 9 automatically forms a generally closed guideway for the sections 10a, b, c of the extension girder. Of course, within the base support 9 nor the guide for the extension support 10 forming guide means may be provided, as indicated in Figure 5 by slide rails 19.
