Description

Die Erfindung betrifft Behälter, bestehend aus einem behälterseitigen Schließmechanismus für am Behälter vorgesehene Entleerungsklappen, der aus einem ersten mit der Behälterwandung fest verbundenen Kupplungsstück und einem zweiten, als Zugstange ausgebildeten Kupplungsstück, das längsverschieblich in einer mit der Behälterwandung verbundenen Buchse geführt und durch flexible Zugelemente in der Weise mit den Entleerungsklappen verbunden ist, daß die Zugelemente bei eingefahrener Zugstange entspannt und bei ausgefahrener Zugstange unter Verschluß der Entleerungsklappen gespannt sind.The invention relates to containers, consisting of a container-side locking mechanism for emptying flaps provided on the container, the first coupling piece firmly connected to the container wall and a second coupling piece designed as a pull rod, which is longitudinally displaceable in a socket connected to the container wall and guided by flexible pulling elements in is connected to the emptying flaps in such a way that the tension elements are relaxed when the drawbar is retracted and tensioned when the drawbar is extended, with the emptying flaps closed.

Behälter der eingangs genannten Art sind beispielsweise aus der EP 0 280 008 A 1 bekannt. Gemäß dieser Ausführung sind die Kupplungsstücke des Behälters als Ösen ausgeführt, in die Last- und Zughaken eines Hebezeuges eingreifen. Beim An- und Abkoppeln des Hebezeugs besteht die Schwierigkeit, daß die Last- und Zughaken jeweils derart mittels des Hebezeugs verdreht und verschoben werden müssen, bis daß sie in die Ösen eingehakt werden können. In der Regel ist hierzu die Hilfestellung durch Bedienungspersonal oder einer eigens dafür vorgesehenen Einrichtung zur Erfassung der beiden Haken notwendig.Containers of the type mentioned are known for example from EP 0 280 008 A1. According to this embodiment, the coupling pieces of the container are designed as eyelets, into which load and pull hooks of a hoist engage. When coupling and uncoupling the hoist there is the difficulty that the load and pull hooks have to be rotated and moved in each case by means of the hoist until they can be hooked into the eyelets. As a rule, the help of operating personnel or a specially provided device for detecting the two hooks is necessary.

Aus der AU-A-89 40 ist ein Behälter bekannt, der zum Betätigen eines Verschlusses ein als Zugstange ausgebildetes Kupplungselement und ein fest mit dem Behälter verbundenes Kupplungsstück aufweist, in welchem das als Zugstange ausgebildete Kupplungsstück beweglich geführt ist. An dem fest mit dem Behälter verbundenen Kupplungsstück ist ein Knopf angeordnet, der an seiner Unterseite die Form eines umgekehrten abgeschnittenen Konus aufweist. Auch an der Zugstange ist ein Knopf ausgebildet, dessen Unterseite als umgekehrter abgeschnittener Konus ausgebildet ist. Bei dieser Ausbildung der knopfartigen Verdickung in dem Kupplungsstück ist es notwendig, daß die entsprechenden Halte-elemente eines die Kupplungsstücke betätigenden Greifers kompakt und kompliziert gebaut werden müssen. Bei dieser Bauweise besteht die Gefahr, daß der Greifer aufgrund der konischen Form der jeweiligen Knopfunterseiten der Kupplungselemente leicht abrutscht.From AU-A-89 40 a container is known which for actuating a closure has a coupling element designed as a pull rod and a coupling piece which is fixedly connected to the container and in which the coupling piece designed as a pull rod is movably guided. On the one firmly attached to the container Coupling piece is arranged a button, which has the shape of an inverted cut-off cone on its underside. A button is also formed on the pull rod, the underside of which is designed as an inverted cut-off cone. With this design of the button-like thickening in the coupling piece, it is necessary that the corresponding holding elements of a gripper actuating the coupling pieces have to be constructed in a compact and complicated manner. With this design there is a risk that the gripper slips easily due to the conical shape of the respective button undersides of the coupling elements.

Es stellt sich daher die Aufgabe, einen gattungsgemäßen Behälter derart weiterzubilden, daß die Handhabungseinrichtung leicht und ohne Fremdhilfe mit dem Behälter gekoppelt werden kann.It is therefore the task of developing a generic container in such a way that the handling device can be coupled to the container easily and without outside help.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Der Vorteil eines solchen Behälters besteht darin, daß eine entsprechende Handhabungseinrichtung zum Anheben und Absenken des Behälters und zum Öffnen und Schließen der Entleerungsklappen nur einfach zentrisch aufgesetzt zu werden braucht, ohne daß eine Einrichtung geschaffen werden muß, mit der die beiden Haken in vorbestimmter Art und Weise erfaßt und geführt werden. Die flanschförmigen Ränder der Kupplungsstücke weisen jeweils auf ihrer Unterseite eine Ringnut mit schräg nach außen hin abfallender Flanke auf. Die eingreifenden Haken der Kupplungseinrichtung eines Hebezeuges werden hier unter dem Gewicht des hochgezogenen Behälters somit nach innen in die umlaufenden Nuten gezogen, so daß sie gegen eine Selbstentriegelung gesichert sind.This object is achieved in a generic device by the characterizing features of claim 1. The advantage of such a container is that a corresponding handling device for lifting and lowering the container and for opening and closing the emptying flaps only needs to be placed centrally without having to create a device with which the two hooks in a predetermined manner and Way to be grasped and led. The flange-shaped edges of the coupling pieces each have an annular groove on their underside with a flank that slopes away towards the outside. The engaging hooks of the coupling device of a hoist are thus pulled under the weight of the hoisted container inwards into the circumferential grooves, so that they are secured against self-unlocking.

Bevorzugte Ausführungsformen des erfindungsgemäßen Behälters ergeben sich aus den Merkmalen der Unteransprüche 2-6. Dabei ist besonders vorteilhaft, wenn die flanschförmigen Ränder ringförmig ausgebildet sind. Dadurch müssen die Haken der Kupplungseinrichtung des zuvorgenannten Hebezeuges nicht ausgerichtet werden, sondern können an einer beliebigen Stelle des Umfangs des jeweiligen flanschförmigen Randes eingreifen.Preferred embodiments of the container according to the invention result from the features of subclaims 2-6. It is particularly advantageous if the flange-shaped edges are annular. As a result, the hooks of the coupling device of the aforementioned lifting device do not have to be aligned, but can engage at any point on the circumference of the respective flange-shaped edge.

In Fig. 1 ist ein auf dem Boden abgestellter Behälter 10 in Igluform dargestellt. Der Behälter 10 besteht aus einem behälterseitigen Schließmechanismus 12 für Entleerungsklappen 14, die am Behälter vorgesehen sind. Im dargestellten Ausführungsbeispiel sind die Entleerungsklappen 14 als Bodenklappen ausgeführt, die um ein mittiges Scharnier 15 nach unten klappbar sind. In gleicher Weise könnte der Behälter aber auch eine beliebige andere Form und beispielsweise bewegbare Seitenklappen aufweisen.1 shows a container 10 placed on the floor in an igloo shape. The container 10 consists of a container-side closing mechanism 12 for emptying flaps 14, which are provided on the container. In the exemplary embodiment shown, the emptying flaps 14 are designed as bottom flaps that can be folded downward about a central hinge 15. In the same way, the container could also have any other shape and, for example, movable side flaps.

An der Oberseite des hier als rotationssymmetrischen Container ausgeführten Behälters 10 ist ein erstes Kupplungsstück 16 aus einer Buchse 22 mit oberem flanschförmigen Rand 24 verschraubt, verschweißt oder anderweitig form- oder stoffschlüssig verbunden. Die Buchse 22 ist dabei zentrisch ausgerichtet. Sie dient gleichzeitig als Führungsbuchse für ein zweites als Zugstange ausgebildetes Kupplungsstück 18. Auch dieses zweite Kupplungsstück 18 hat einen oberen flanschförmigen Rand 26. In der Grundstellung liegt dieser obere flanschförmige Rand 26 oberhalb des oberen flanschförmigen Randes 24 des ersten Kupplungsstücks 16. Die Zugstange des zweiten Kupplungsstücks 18 ragt in das Innere des Behälters 10 hinein. Am unteren Ende der Zugstange sind Zugelemente 23 angeschlossen, die mit den frei schwenkbaren Enden der Entleerungsklappen 14 verbunden sind. Im eingefahrenen Zustand der Zugstange des zweiten Kupplungsstücks 18 sind die Zugelemente 23 entspannt, wie es in Fig. 1 dargestellt ist.On the upper side of the container 10, which is designed here as a rotationally symmetrical container, a first coupling piece 16 is screwed, welded or otherwise positively or materially connected from a bush 22 with an upper flange-shaped edge 24. The bushing 22 is aligned centrally. It also serves as a guide bush for a second coupling piece 18 designed as a pull rod. This second coupling piece 18 also has an upper flange-shaped edge 26. In the basic position, this upper flange-shaped edge 26 lies above the upper flange-shaped edge 24 of the first coupling piece 16. The pull rod of the second Coupling piece 18 projects into the interior of the container 10. At the lower end of the drawbar are tension elements 23 connected, which are connected to the freely pivotable ends of the emptying flaps 14. In the retracted state of the pull rod of the second coupling piece 18, the pull elements 23 are relaxed, as shown in FIG. 1.

Die Buchse 22 weist eine quadratische Bohrung und die Zugstange des zweiten Kupplungsstücks 18 ein komplementäres Profil auf. Dadurch wird gewährleistet, daß die Zugstange nicht um ihre eigene Achse rotiert, wodurch die Zugelemente 23 in ihrer freien Beweglichkeit aufgrund Verdrehens oder Verschlingens untereinander beeinträchtigt werden könnten. Grundsätzlich sind aber auch andere Bohrungsquerschnitte der Buchse 22 möglich.The bushing 22 has a square bore and the pull rod of the second coupling piece 18 has a complementary profile. This ensures that the pull rod does not rotate about its own axis, as a result of which the free movement of the pull elements 23 could be impaired as a result of twisting or engaging with one another. In principle, however, other bore cross sections of the bushing 22 are also possible.

In Fig. 1 ist weiterhin schematisch die Kupplungseinrichtung 30 eines Hebezeuges 32 zur Handhabung des Behälters 10 dargestellt. Die Kupplungseinrichtung 30 ist über eine Anhängeöse 40 mit dem Hebezeug verbolzt. Zentrales Element der Kupplungseinrchtung sind ein unteres und ein oberes Hakenpaar 34 bzw. 36. Dabei dient das untere Hakenpaar dazu, mit dem ersten Kupplungsstück 16 in Eingriff zu gehen. Das obere Hakenpaar 36 kann mit dem zweiten Kupplungsstück 18 in Eingriff gehen. Die flanschförmigen Ränder 24 und 26 der Kupplungsstücke 16 und 18 sind ringförmig ausgebildet und auf ihrer Unterseite ist je eine Ringnut 28 bzw. 29 mit einer schräg nach außen hin abfallenden Flanke vorgesehen. Die Haken 34 und 36 der Kupplungseinrichtung 30 werden durch Eingriff in diese Ringnuten 28 bzw. 29 zusätzlich dadurch gesichert, daß sie insbesondere unter der Last des Behälters in die Ringnut hineingezogen werden.In Fig. 1, the coupling device 30 of a hoist 32 for handling the container 10 is also shown schematically. The coupling device 30 is bolted to the lifting device via a towing eye 40. The central element of the coupling device is a lower and an upper pair of hooks 34 and 36, respectively. The lower pair of hooks serves to engage the first coupling piece 16. The upper pair of hooks 36 can engage the second coupling piece 18. The flange-shaped edges 24 and 26 of the coupling pieces 16 and 18 are ring-shaped and on their underside there is an annular groove 28 and 29, respectively, with a flank sloping outwards. The hooks 34 and 36 of the coupling device 30 are additionally secured by engagement in these annular grooves 28 and 29, respectively, in that they are drawn into the annular groove in particular under the load of the container.

Die unteren Haken 34 der Kupplungseinrichtung stellen die Lasthaken dar, d.h. mittels dieser Haken wird über den fest mit dem Behälter 10 verbundenen Kupplungsstück 16 der gesamte Behälter hochgehoben. Bevor dies jedoch möglich ist, müssen mittels der Zugelemente 23 die Entleerungsklappen 14 gegen ein Öffnen beim Hochheben des Behälters 10 vom Boden gesichert werden. Dazu wird das zweite Kupplungsstück 18 mittels der Haken 36 nach oben gezogen, bis die Zugelemente 23 gespannt sind, so daß damit ein Aufklappen der Entleerungsklappen 14 beim Abheben des Behälters 10 vom Boden verhindert wird. Dabei wird die innere Vierkantzugstange des zweiten Kupplungsstücks um ca. 50 cm herausgezogen. In dieser Stellung der Kupplungseinrichtung 30 wird der Behälter beispielsweise mittels eines Auslegers 32 eines nicht dargestellten Krans angehoben und über die zu befüllende Ladefläche beispielsweise eines LKW's geschwenkt. Durch Absenken der Zugstange und damit der Zugelemente 23 werden die Entleerungsklappen 14 geöffnet, so daß der gesammelte Inhalt, z.B. Abfall, aus dem Behälter herausfällt.The lower hooks 34 of the coupling device represent the load hooks, ie by means of these hooks the entire container is lifted up via the coupling piece 16 which is firmly connected to the container 10. Before this is possible, however, the Tension elements 23, the emptying flaps 14 are secured against opening when the container 10 is lifted from the floor. For this purpose, the second coupling piece 18 is pulled upwards by means of the hooks 36 until the tension elements 23 are tensioned, so that this prevents the emptying flaps 14 from opening when the container 10 is lifted off the floor. The inner square pull rod of the second coupling piece is pulled out by approx. 50 cm. In this position of the coupling device 30, the container is raised, for example by means of a boom 32 of a crane, not shown, and pivoted over the loading area to be filled, for example of a truck. By lowering the pull rod and thus the pulling elements 23, the emptying flaps 14 are opened, so that the collected content, for example waste, falls out of the container.

Der Behälter wird analog der vorbeschriebener Weise wieder geschlossen und auf dem Boden abgesetzt.The container is closed again in the same way as described above and placed on the floor.

Die Haken 36, die zur Auf- und Abbewegung der Zugstange des zweiten Kupplungsstücks 18 dienen, werden mittels einer im Gehäuse liegenden heb- und absenkbaren Auszugsvorrichtung 46 verfahren, wie aus Figur 1 zu sehen ist. Diese Auszugsvorrichtung 46 besteht aus einer hydraulischen Kolben-Zylinder-Einheit, deren Zylinder mit einem die schwenkbaren Haken 36 tragenden Joch 48 und deren Kolbenstange 50 mit ihrem oberen Ende am oberen Endbereich des Gehäuses 38 befestigt ist. Die Kolben-Zylinder-Einheit ist von einer Druckfeder umgeben, die das Joch 48 derart beaufschlagt, daß der Zylinder mit den Haken 36 nach unten geschoben wird. Gleichzeitig wird Hydraulikflüssigkeit durch eine Bohrung in der Kolbenstange 50 (nicht dargestellt) aus dem Zylinder verdrängt. Zum Hochfahren des Zylinders und damit der Haken 36 wird über eine nicht dargestellte Hydraulikleitung wieder Hydraulikflüssigkeit zugeführt, so daß der Kolben innerhalb der Kolben-Zylinder-Einheit gegen die Federkraft der Druckfeder 52 entlang des Zylinders verschoben wird. Damit ist zur Betätigung der Auszugsvorrichtung 46 nur eine Hydraulikleitung (nicht dargestellt) vorzusehen.The hooks 36, which serve to move the pull rod of the second coupling piece 18 up and down, are moved by means of a pull-out device 46 which can be raised and lowered in the housing, as can be seen from FIG. This pull-out device 46 consists of a hydraulic piston-cylinder unit, the cylinder of which is fastened to the upper end region of the housing 38 with a yoke 48 carrying the pivotable hooks 36 and the piston rod 50 of which is fastened with its upper end. The piston-cylinder unit is surrounded by a compression spring which acts on the yoke 48 in such a way that the cylinder is pushed downwards with the hooks 36. At the same time, hydraulic fluid is displaced from the cylinder through a bore in the piston rod 50 (not shown). To start up the cylinder and thus the hook 36, hydraulic fluid is supplied again via a hydraulic line, not shown, so that the piston within the piston-cylinder unit is displaced along the cylinder against the spring force of the compression spring 52. Thus, only one hydraulic line (not shown) has to be provided for actuating the pull-out device 46.

Um 90° in Drehrichtung zu den oberen Haken 36 versetzt sind die unteren Haken 34 im Gehäuse 38 der Kupplungseinrichtung 30 ortsfest und um eine Achse 42 schwenkbar gelagert angeordnet, wie aus Figur 2 ersichtlich. Die unteren Haken 34 werden aus ihrer Schließstellung, d.h. ihrem Eingriff mit der ersten Kupplungseinrichtung 16 durch hydraulische Kolben-Zylinder-Einheiten 62 in Öffnungsrichtung geschwenkt. Dabei werden sie gegen die Federkraft von in Führungsstangen 58 eingefaßten Druckfedern 54 bewegt. Zum Zurückschwenken der Haken 34 zum Eingriff unter den flanschförmigen Rand 24 des ersten Kupplungsstücks 16 dienen die Druckfedern 54, die den Haken 34 in Schließrichtung beaufschlagen. Gleichzeitig wird die Hydraulikflüssigkeit in den Kolben-Zylinder-Einheiten verdrängt. Auch an den oberen Haken 36 sind Führungsstangen 60 angelenkt, welche durch Druckfedern 56 eingefaßt sind. Diese beaufschlagen die Haken 36 ebenfalls in Schließrichtung, d.h. sie verschwenken die Haken 36 um die am Joch 48 der Auszugsvorrichtung 46 angeordneten Achsen 44, so daß die Haken unter den flanschförmigen Rand 26 des zweiten Kupplungsstücks 18 greifen. Um die Haken 36 auszuschwenken werden sie am Anlenkpunkt der Führungsstange 60 mit frei ausfahrbaren Kolben 66 von Kolben-Zylinder-Einheiten 64 beaufschlagt. Auch in diesem Fall ist für die Kolben-Zylinder-Einheiten jeweils nur eine einseitige Hydraulikzuführung notwendig, da eine Rückstellung, d.h. ein Einschwenken der oberen Haken 36 in die Eingriffsposition mit dem oberen flanschförmigen Teil 26 des zweiten Kupplungsstücks 18, infolge der Federkraft der Druckfeder 56 erfolgt.Offset by 90 ° in the direction of rotation to the upper hooks 36, the lower hooks 34 are arranged in a fixed manner in the housing 38 of the coupling device 30 and are pivotably mounted about an axis 42, as can be seen from FIG. The lower hooks 34 are removed from their closed position, i.e. their engagement with the first clutch device 16 is pivoted in the opening direction by hydraulic piston-cylinder units 62. They are moved against the spring force by compression springs 54 enclosed in guide rods 58. The compression springs 54, which act on the hook 34 in the closing direction, serve to pivot the hooks 34 back for engagement under the flange-shaped edge 24 of the first coupling piece 16. At the same time, the hydraulic fluid in the piston-cylinder units is displaced. Guide rods 60 are also articulated on the upper hooks 36 and are surrounded by compression springs 56. These also act on the hooks 36 in the closing direction, i.e. they pivot the hooks 36 about the axes 44 arranged on the yoke 48 of the pull-out device 46, so that the hooks engage under the flange-shaped edge 26 of the second coupling piece 18. In order to pivot the hooks 36, they are loaded with freely extendable pistons 66 by piston-cylinder units 64 at the articulation point of the guide rod 60. In this case too, only one-sided hydraulic supply is required for the piston-cylinder units, since a reset, i.e. the upper hooks 36 pivot into the engagement position with the upper flange-shaped part 26 of the second coupling piece 18, as a result of the spring force of the compression spring 56.

Alle die Haken 34 und 36 beaufschlagenden Kolben-Zylinder-Einheiten 62 bzw. 64 werden über eine Hydraulikspeiseleitung versorgt. Damit können die Kolben der Kolben-Zylinder-Einheiten 62 bzw. 64 nur gleichzeitig ausgefahren werden.All piston-cylinder units acting on the hooks 34 and 36 62 and 64 are supplied via a hydraulic feed line. The pistons of the piston-cylinder units 62 and 64 can thus only be extended at the same time.

Beim Ausfahren des Kolbens 66 gegen den Anlenkpunkt 61 besteht allerdings die Gefahr, daß die Kolbenbewegung des Kolbens 66 nicht nur in eine Schwenkbewegung des Hakens 36 um die Achse 44 umgesetzt wird, sondern daß auch eine Längsverschiebung des Joch 48 gegen die Federkraft der Druckfeder 52 erfolgt, wobei der Haken 36 in der Nut 30 verhakt bleibt und an einer Ausschenkbewegung gehindert wird. Dies wird dadurch verhindert, daß das Joch 48 während der Ausschwenkbewegung der Haken 36 im Verhältnis zum Behälter 10 ortsfest gehalten wird. Dazu dienen zwei Verriegelungshebel 68. Diese sind um die Schwenkachsen 42 der unteren Haken schwenkbar gelagert. In der Eingriffsposition der unteren Haken 34 und somit auch der oberen Haken 36 sind die Verriegelungshebel 68 in eine geöffnete Position verschwenkt, so daß das Joch 48 mitsamt der Haken 36 über die Auszugsvorrichtung 46 hochgeschoben werden kann. In dieser Position ist der Verriegelungshebel in Fig. 3 in durchgezogener Linie dargestellt. Beim Ausschwenken der Haken 34 und 36 müssen die Hebel 68 jeweils über Widerlager bildende Vorsprünge 74 des Jochs 48 greifen. Die Verriegelungshebel 68 werden über die Kolbenstangen 70 der Kolben-Zylinder-Einheiten 62, an die sie angelenkt sind, verschwenkt. Um ein Verschwenken der Verriegelungshebel 68 in ihrer Schließposition gegenüber einem Verschwenken der Hebel 34 in ihre geöffnete Position zeitlich zu versetzen, sind die unteren Haken 34 mit den Kolben 70 der Kolben-Zylinder-Einheiten 62 über hakenseitige Langlöcher 72, in welche zylinderseitige Bolzen 71 eingreifen verbunden. Damit funktioniert der Verriegelungsmechanismus wie folgt: Beim Ausfahren des Kolbens 70 wird der Verriegelungshebel 68 von seiner ausgeschwenkten Freigabeposition in die Verriegelungsposition geschoben. Die unteren Haken 34 können aufgrund des Langlochs 72 während des ersten Hubteils des Kolbens 70 in ihrer Verriegelungsposition verbleiben. Erst wenn der kolbenseitige Zapfen am Ende des Langlochs 72 anliegt wird der entsprechende untere Haken 34 aus seiner Eingriffsposition ausgeschwenkt. Durch das zuvor beschriebene Zusammenwirken der Haken 34, 36 und der Verriegelungshebel 68 ist eine vorschriftsmäßige Entriegelung der Kupplungseinrichtung gewährleistet.When extending the piston 66 against the articulation point 61, there is, however, the risk that the piston movement of the piston 66 is not only converted into a pivoting movement of the hook 36 about the axis 44, but also that the yoke 48 is displaced longitudinally against the spring force of the compression spring 52 , wherein the hook 36 remains hooked in the groove 30 and is prevented from pivoting out. This is prevented by the yoke 48 being held stationary in relation to the container 10 during the swiveling-out movement of the hooks 36. Two locking levers 68 are used for this purpose. These are pivotally mounted about the pivot axes 42 of the lower hooks. In the engaged position of the lower hooks 34 and thus also the upper hooks 36, the locking levers 68 are pivoted into an open position, so that the yoke 48 together with the hooks 36 can be pushed up via the pull-out device 46. In this position, the locking lever is shown in Fig. 3 in a solid line. When the hooks 34 and 36 are pivoted out, the levers 68 must each engage over projections 74 of the yoke 48 which form abutments. The locking levers 68 are pivoted via the piston rods 70 of the piston-cylinder units 62 to which they are articulated. In order to move a pivoting of the locking lever 68 in its closed position in relation to a pivoting of the lever 34 into its open position, the lower hooks 34 with the pistons 70 of the piston-cylinder units 62 are via hook-side elongated holes 72, in which cylinder-side bolts 71 engage connected. The locking mechanism thus functions as follows: When the piston 70 is extended, the locking lever 68 is pushed from its swung-out release position into the locking position. The lower hook 34 can remain in their locking position due to the elongated hole 72 during the first stroke part of the piston 70. Only when the piston-side pin abuts the end of the elongated hole 72 is the corresponding lower hook 34 pivoted out of its engaged position. The previously described interaction of the hooks 34, 36 and the locking lever 68 ensures correct unlocking of the coupling device.

In Fig. 5 ist der obere Teil einer besonderen Ausführungsform der zuvor beschriebenen Kupplungseinrichtung dargestellt. Eine Kupplungseinrichtung gemäß dieser Ausführungsform ermöglicht eine Verdrehung des unteren Teils 84 des Gehäuses 38 mitsamt der im unteren Teil angeordneten Hakenpaare 34 und 36 und einem angehängten Abfallbehälter 10. Dies ist insbesondere dann notwendig, wenn es sich nicht um einen rotationssymmetrischen Behälter, beispielsweise einen rechteckigen Behälter, handelt. Der obere Teil 80 des Gehäuses 38 ist mit dem unteren Gehäuseteil 84 über eine Drehdurchführung 82 verbunden. Die Verdrehung des unteren Gehäuses 84 erfolgt über einen hydraulisch antreibbaren Drehmotor 88. Ein an diesem angeflanschtes Ritzel 90 kämmt mit einem Zahnrad 92, das mit dem unteren Teil 84 des Gehäuses 38 verbunden ist. Bei dieser Ausführungsform ist der Kolben 50 der Auszugsvorrichtung 46 in einem Käfig 86 aufgehängt. Der Käfig 86 ist im unteren Gehäuseteil 84 pendelnd aufgehängt, so daß er mit diesem mitrotiert. Er ragt allerdings in das obere Gehäuseteil 80 hinein.5 shows the upper part of a particular embodiment of the coupling device described above. A coupling device according to this embodiment enables rotation of the lower part 84 of the housing 38 together with the pairs of hooks 34 and 36 arranged in the lower part and an attached waste container 10. This is particularly necessary if it is not a rotationally symmetrical container, for example a rectangular container , acts. The upper part 80 of the housing 38 is connected to the lower housing part 84 via a rotary feedthrough 82. The lower housing 84 is rotated via a hydraulically drivable rotary motor 88. A pinion 90 flanged to this meshes with a gear 92 which is connected to the lower part 84 of the housing 38. In this embodiment, the piston 50 of the pull-out device 46 is suspended in a cage 86. The cage 86 is suspended in the lower housing part 84 so that it rotates with it. However, it projects into the upper housing part 80.

Der hydraulische Drehmotor kann in üblicher Weise für Links- und Rechtslauf vorgesehen sein und demnach mit 2 Hydraulikleitungen verbunden werden.The hydraulic rotary motor can be provided in the usual way for left and right rotation and can therefore be connected to two hydraulic lines.

Sämtliche zuvor beschriebenen Kupplungsmechanismen, d.h. die ersten und zweiten Kupplungsstücke 16 bzw. 18 des Behälters 10 und die Hakenpaare 34 bzw. 36, sowie die Verriegelungshebel 68 sind rotationssymmetrisch um eine gemeinsame Mittelachse angeordnet.All of the coupling mechanisms described above, ie the first and second coupling pieces 16 and 18 of the container 10 and the pairs of hooks 34 and 36, as well as the locking levers 68, are arranged rotationally symmetrically about a common central axis.
