Description

Die Erfindung bezieht sich auf ein Fahrzeug mit einem Behälter und einem am Behälter angeschlossenen Saugschlauch nach den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a vehicle with a container and an am Container connected suction hose according to the features of the generic term of claim 1.

Ein Fahrzeug mit einem Behälter und einem am Behälter angeschlossenen Saugschlauch ist in der DE-PS 30 02 557 (= US-PS 4 446 591) gezeigt und beschrieben. Bei diesem Fahrzeug ist auf dem Behälter liegend eine Haspel mit vertikaler Drehachse zur Aufnahme des Saugschlauches vorgesehen. Von der Haspel distanziert und ebenfalls an der Oberseite des Behälters angeordnet ist ein Drehkranz vorgesehen mit vertikaler Drehachse, an dem ein als Ausleger für den Saugschlauch dienender Arm festgelegt ist. Da der Abstand zwischen der Haspel und dem Ausleger bzw. dessen Drehkranz aus anlagen- und konstruktionsbedingten Gründen relativ klein ist, kann der Ausleger nur in sehr beschränktem Umfang verschwenkt werden, damit das zwischen Haspel und Ausleger liegende Schlauchtrum nicht zu stark geknickt wird.A vehicle with a container and a suction hose connected to the container is shown and described in DE-PS 30 02 557 (= US Pat. No. 4,446,591). In this vehicle there is a vertical reel lying on the container Axis of rotation provided for receiving the suction hose. Distanced from the reel and also on the top of the container is a slewing ring provided with a vertical axis of rotation, on which a boom for the Suction hose serving arm is fixed. Because the distance between the reel and the boom or its slewing ring from system and design-related Reasons is relatively small, the boom can only be very limited Circumference can be pivoted so that the lying between reel and boom Hose run is not kinked too much.

Andere Fahrzeuge vergleichbarer Art besitzen anstelle der erwähnten Haspel eine an der Oberseite des liegenden Behälters waagrecht liegende, rechteckige Auflagebühne für den Schlauch. Diese Auflagebühne erstreckt sich über die gesamte Länge des Fahrzeuges und ist am Behälter festgelegt. An der rückseitigen Schmalseite der rechteckigen Auflagebühne, und zwar im einen Eckbereich ist eine Aus- und Einziehvorrichtung für den Saugschlauch festgelegt. Im Bereich der anderen Ecke der Auflagebühne ist die Durchführung für den Schlauch angeordnet. Der um eine vertikale Achse verschwenkbare und in der Regel auch längenveränderbare Ausleger für den Saugschlauch ist von der Auflagebühne getrennt am Behälter festgelegt. Auch hier bei dieser Konstruktion kann daher der Ausleger nur in einem sehr beschränkten Umfang verschwenkt werden, weil ansonsten das zwischen der Aus- und Einziehvorrichtung und dem Ausleger liegende Schlauchtrum zu stark geknickt würde. Fahrzeuge dieser Art sind beschrieben und gezeigt im Prospekt der Firma Müller-Umwelttechnik GmbH. & Co. KG (April 89) und der Firma Faun Eurotec-Vertriebsgesellschaft für Entsorgungstechnik (8/91). Other vehicles of a similar type have instead of the reel mentioned a rectangular one lying horizontally on the top of the lying container Support platform for the hose. This platform extends over the entire Length of the vehicle and is fixed on the container. On the back Narrow side of the rectangular platform, namely in a corner area a pull-out and pull-in device for the suction hose. In the area the passage for the hose is arranged at the other corner of the support platform. The one that can be swiveled around a vertical axis and usually also variable in length The boom for the suction hose is separated from the platform fixed on the container. Here too, with this construction, the Boom can only be pivoted to a very limited extent, because otherwise that between the pull-out and pull-in device and the boom Hose run would be kinked too much. Vehicles of this type are described and shown in the brochure of Müller-Umwelttechnik GmbH. & Co. KG (April 89) and Faun Eurotec-Vertriebsgesellschaft für Entsorgungstechnik (8/91).

Weiters ist noch das bekanntgewordene Schlammsaugfahrzeug nach US-A-4 213 479 zu erwähnen, das an der Oberseite des Behälters eine um eine vertikale Achse verschwenkbare Schlauchdurchführung aufweist. In dieser Schlauchdurchführung ist eine Verschlußklappe vorgesehen, die über eine seitlich auskragende Kolben-Zylinder-Einheit betätigbar ist. Diese Kolben-Zylinder-Einheit hat hier keine weitere Funktion zu erfüllen, als die erwähnte Verschlußklappe im Bedarfsfall zu betätigen.Furthermore, the sludge suction vehicle according to US-A-4 213 which has become known 479 to mention the one at the top of the container one by one vertical Has axis swiveling hose bushing. In this hose duct a closure flap is provided, which has a laterally projecting Piston-cylinder unit is actuated. This piston-cylinder unit has none here to fulfill further function than the mentioned closure flap if necessary to operate.

Aus der DE-U-88 07 777, von der der Oberbegriff des Anspruchs 1 als nächstkommendem Stand der Technik ausgeht, ist ebenfalls ein über eine Antriebseinheit ein- und ausfahrbarer Saugschlauch vorgesehen, der auf einer hier rechteckigen Auflagebühne aufliegt. An einer Längsseite der Auflagebühne ist ein als Teleskoprohr ausgebildeter, den Saugschlauch führender Ausleger vorgesehen, der um eine Horizontalachse schwenkbar an der Auflagebühne gelagert ist. Das Teleskoprohr besteht aus einem Außenrohr und einem ausfahrbaren Innenrohr. Im Bereich der der Durchführung benachbarten Stirnseite der Auflagebühne sind um vertikale Achsen drehbare Walzen zur Führung des Schlauchs vorgesehen. Soll der Schlauch bei dieser Einrichtung von der ausgefahrenen Stellung in die eingefahrene Stellung eingefahren werden, so dienen zur Führung des Schlauches das Teleskoprohr und die genannten Walzen und allenfalls noch die Innenseite eines die Auflagebühne überspannenden Bügels. Auf den Schlauch wirkt beim Einfahren des Schlauches, ausgehend von der ausgefahrenen Stellung, eine schiebende Beanspruchung. Dabei besteht die Gefahr, daß der Schlauch seitlich ausknickt, beispielsweise in Richtung des Zentrums der Auflagefläche, wodurch ein ordnungsgemäßes Einfahren des Schlauches verhindert wird. Es könnte dabei zu einer Blockierung des weiteren Einfahrens des Schlauches oder sogar zu einem Knicken des Schlauches kommen. Dabei ist zu berücksichtigen, daß die Biegeelastizität eines Schlauches sich im Laufe von dessen Verwendung infolge häufigen Biegens verändern kann, so daß diese Probleme auch bei einer anfänglich funktionierenden Einrichtung auftreten können. Auch die Eigenschaften der Oberfläche der Auflagebühne können sich im Laufe der Zeit ändern.From DE-U-88 07 777, of which the preamble of claim 1 is the closest State of the art is also a drive unit retractable and extendable suction hose provided on a rectangular here Support platform rests. On one long side of the platform is an as Telescopic tube designed booms guiding the suction hose, which is pivotally mounted on the support platform about a horizontal axis. The Telescopic tube consists of an outer tube and an extendable inner tube. In the area of the end of the support platform that is adjacent to the feedthrough Rollers rotatable about vertical axes are provided for guiding the hose. Should the hose in this device move from the extended position to the retracted position are used to guide the hose the telescopic tube and the rollers mentioned and possibly the inside a bracket spanning the support platform. Acts on the hose when retracting the hose, starting from the extended position, a pushing load. There is a risk that the hose buckles laterally, for example in the direction of the center of the support surface, which prevents the hose from running in properly. It could block the further retraction of the hose or even kink the hose. It must be taken into account that the bending elasticity of a hose changes in the course of its use due to frequent bending can change, so that these problems even with one initially functioning facility can occur. The properties too The surface of the platform can change over time.

Aufgabe der Erfindung ist es, die Probleme der in der DE-U-88 07 777 gezeigten Einrichtung zu überwinden und diese Einrichtung dahingehend zu verbessern, daß bei einer einfachen Ausbildung der Einrichtung ein problemloses und auch durch die Belastungen im Dauerbetrieb nicht beeinträchtigtes Ein- und Ausfahren des Schlauches ermöglicht wird. Erfindungsgemäß gelingt dies durch jene Maßnahmen und Merkmale, die Inhalt und Gegenstand des kennzeichnenden Teiles des Patentanspruches 1 sind. Zweckmäßige Ausführungsformen der Erfindung sind in den Unteransprüchen definiert.The object of the invention is to solve the problems shown in DE-U-88 07 777 Overcoming the facility and improving that facility that with a simple training of the facility a problem-free and also retraction and extension unaffected by the stresses in continuous operation of the hose is made possible. According to the invention, this is achieved through those measures and features, the content and subject of the characterizing part of claim 1 are. Appropriate embodiments of the invention are defined in the subclaims.

Die Längsmittelachse des liegenden Behälters 2 ist in den Fig. 2 und 3 durch eine strichpunktierte Linie 7 angedeutet. Diese scheibenartige Auflagebühne 4 ist um eine vertikale Achse 8 verschwenkbar gelagert, die in der Mitte dieser scheibenartigen Auflagebühne 4 liegt. Diese Verschwenkmöglichkeit ist durch den Pfeil 9 angedeutet.The longitudinal central axis of the lying container 2 is in FIGS. 2 and 3 by a dash-dotted line 7 indicated. This disc-like platform 4 is around a vertical axis 8 pivotally mounted in the middle of this disc-like Support platform 4 is located. This pivoting option is indicated by arrow 9 indicated.

Koaxial zu dieser vertikal stehenden Achse 8 ist die Durchführung 11 des Schlauches 3 drehbar bzw. verschwenkbar gelagert, an deren einer Seite 12 das Ende des Schlauches 3 angeschlossen ist. Die Mündungsebene dieses Schlauchendes steht rechtwinkelig zur Auflageebene der Auflagebühne 4. Innerhalb dieser Armatur, die die Durchführung 11 bildet, ist hier eine nicht sichtbare Verschlußklappe angeordnet, die mittels einer Kolben-Zylinder-Einheit 13 betätigbar ist. Diese Kolben-Zylinder-Einheit 13 erstreckt sich - bezogen auf die vertikale Achse 8 - radial und liegt parallel zur Auflageebene der Auflagebühne 4. Sie liegt bezüglich des Anschlusses des Saugschlauches diametral. Ihre axiale Länge entspricht etwa dem halben Radius der scheibenartigen Auflagebühne 4 und an ihrem Ende trägt diese Kolben-Zylinder-Einheit eine um eine vertikale Achse frei drehbare Walze 14. Entlang des Umfanges der Auflagebühne 4 ist eine Vielzahl von um vertikale Achsen frei drehbare Walzen 15 vorgesehen, deren Länge zumindest dem halben Durchmesser des Saugschlauches 3 entspricht. Zur Verschwenkung der Auflagebühne 4 im Sinne des Pfeiles 9 ist ein hier nicht dargestellter Motor vorgesehen.The passage 11 of the hose is coaxial to this vertical axis 8 3 rotatably or pivotably, on one side 12 the end of the hose 3 is connected. The mouth level of this hose end is at right angles to the support level of the support platform 4. Within this fitting, which forms the feedthrough 11, a non-visible closure flap is arranged here, which can be actuated by means of a piston-cylinder unit 13. This piston-cylinder unit 13 extends - in relation to the vertical axis 8 - radially and is parallel to the support plane of the support platform 4. It is in relation to the Connection of the suction hose diametrically. Their axial length corresponds approximately to that half the radius of the disc-like support platform 4 and at its end carries this Piston-cylinder unit a roller 14 freely rotatable about a vertical axis. Along the circumference of the platform 4 is a variety of vertical Axles freely rotatable rollers 15 are provided, the length of which is at least half Diameter of the suction hose 3 corresponds.

Fig. 2 zeigt in Draufsicht diese Auflagebühne 4 mit eingezogenem bzw. eingefahrenem Saugschlauch 3, der sich entlang der Walzen 15 erstreckt, der Saugschlauch 3 ist also aufgelegt. Zum betriebsmäßigen Einsatz muß der Saugschlauch 3 ausgefahren werden. Zu diesem Zweck wird die Ein- und Ausziehvorrichtung 5 zugeschaltet und auch der Ausleger 6 ausgefahren, der sich dann - Fig. 2 - nach rechts (Pfeil 16) bewegt. Durch die Inbetriebnahme der letzterwähnten Aggregate wird nun der auf der Auflageebene der Auflagebühne 4 bevorratete Saugschlauch 3 abgezogen, wobei sich bei stillstehender Auflagebühne 4 die Durchführung 11 um die Achse 8 verdreht bzw. verschwenkt, so daß, wenn der Saugschlauch 3 zur Gänze ausgefahren ist, sich das aus Fig. 3 ersichtliche Lagebild ergibt, wobei sich diese Durchführung 11 um ca. 330° bewegt hat. Unabhängig von dieser Bewegung des Saugschlauches 3, der Durchführung 11 und des Auslegers 6 kann nun die Auflagebühne 4 als Ganzes um die Achse 8 verschwenkbar werden, so daß der Ausleger 6 mit dem abhängenden Schlauchende einen Winkelbereich von annähernd 300° überstreichen kann, ohne daß sich dadurch die Lage des auf der Auflagebühne 4 befindlichen Schlauchabschnittes ändert. Beim Abziehen des Saugschlauches 3 wird der auf der Auflagebühne 4 befindliche Abschnitt des Saugschlauches 3 durch die Walze 14 in radialer Richtung gestützt. Diese frei drehbare Walze 14 ist hier am Ende einer Kolben-Zylinder-Einheit 13 angeordnet, die zur Betätigung einer Verschlußklappe dient, die in der als Durchführung 11 dienenden Armatur angeordnet ist. Die Achse dieser Kolben-Zylinder-Einheit 13 liegt parallel zur Auflageebene der Auflagebühne 4. Darüber hinaus ist diese Kolben-Zylinder-Einheit 13, bezogen auf die Achse 8 der drehbar gelagerten Durchführung 11, diametral zur Anschlußmündung des Saugschlauches 3 sich radial erstreckend angeordnet. Falls kein Stellglied oder Betätigungsglied für eine Verschlußklappe erforderlich ist, kann anstelle dieser Kolben-Zylinder-Einheit 13 auch ein einfacher Auslegerarm vorgesehen werden.Fig. 2 shows a top view of this support platform 4 with the retracted or retracted Suction hose 3, which extends along the rollers 15, the suction hose So 3 is on the hook. For operational use, the suction hose 3 must be extended become. For this purpose, the pull-in and pull-out device 5 is switched on and also the boom 6 extended, which then - Fig. 2 - to the right (Arrow 16) moves. By commissioning the last mentioned units now remove the suction hose 3 stored on the support level of the support platform 4, with the implementation 11 around when the support platform 4 is stationary the axis 8 rotated or pivoted so that when the suction hose 3 for Is completely extended, the position picture shown in FIG. 3 results, whereby this bushing 11 has moved by approximately 330 °. Regardless of this movement the suction hose 3, the bushing 11 and the boom 6 can now the support platform 4 as a whole can be pivoted about the axis 8, so that the Boom 6 with the depending hose end an angular range of approximately Can sweep 300 ° without changing the position of the on the platform 4 located hose section changes. When removing the suction hose 3 becomes the section of the suction hose located on the support platform 4 3 supported by the roller 14 in the radial direction. This freely rotatable Roller 14 is arranged here at the end of a piston-cylinder unit 13, which for Actuation of a closure flap is used, which serves as the implementation 11 Faucet is arranged. The axis of this piston-cylinder unit 13 is parallel to the support level of the support platform 4. In addition, this piston-cylinder unit 13, based on the axis 8 of the rotatably mounted bushing 11, arranged radially extending diametrically to the connection mouth of the suction hose 3. If no actuator or actuator is required for a shutter is, instead of this piston-cylinder unit 13, a simple one Cantilever arm are provided.

Die Walzen 15, die randseitig an der Auflagebühne 4 um vertikal stehende Achsen frei drehbar gelagert sind, erleichtern das Einfahren des Saugschlauches 3. Der einfahrende Saugschlauch 3 legt sich an diesen frei drehbaren Walzen 15 an und kann daher ohne besonderen Kraftaufwand eingefahren werden. Zum Einfahren dient die Ein- und Ausziehvorrichtung 5. Die axiale Erstreckung dieser Walzen 15 ist daher mindestens so groß wie der halbe Durchmesser des Saugschlauches 3, vorzugsweise jedoch etwas größer.The rollers 15, the edge of the support platform 4 around vertical axes are freely rotatable, make it easier to retract the suction hose 3. The retracting suction hose 3 rests on these freely rotatable rollers 15 and can therefore be retracted without any special effort. To drive in serves the pull-in and pull-out device 5. The axial extent of this Rollers 15 is therefore at least as large as half the diameter of the suction hose 3, but preferably slightly larger.

Die Achse 8, um die sowohl die Auflagebühne 4 wie auch die Durchführung 11 unabhängig voneinander verschwenkbar sind, liegt bei dem hier gezeigten Ausführungsbeispiel in einer vertikalen Längsmittelebene des Behälters 2.The axis 8 about which both the support platform 4 and the bushing 11th are independently pivotable, lies in the embodiment shown here in a vertical longitudinal center plane of the container 2.

Dank der erfindungsgemäßen Konstruktion nimmt der auf der Auflagebühne 4 befindliche Schlauch gegenüber dem Ausleger 6 unabhängig von dessen jeweiliger Verschwenkung gegenüber der Längsmittelachse 7 des Fahrzeuges stets dieselbe Lage ein.
