Beschreibungdescription
Die Erfindung betrifft eine Hubvorrichtung zum Anheben und Absenken von Müllbehältern mit einer Aufhahmeeinrichtung zum Erfassen mindestens eines Müllbehälters, die an mindestens einem in vertikaler Richtung beweglichen Seil oder Ketten befestigt ist, das/die von einem Antriebsmotor bewegt wird.The invention relates to a lifting device for lifting and lowering refuse containers with a receiving device for detecting at least one refuse container, which is attached to at least one rope or chain movable in the vertical direction, which is / are moved by a drive motor.
Derartige Hubvorrichtungen werden an Müllfahrzeugen sowohl bei den sogenannten Seitenladern als auch bei den Heckladern eingesetzt. Die Müllbehälter werden mittels dieser Hubvorrichtungen vom Boden abgehoben und zur Einschüttöffiiung transportiert, wo die Behälter durch Verschwenken entleert werden. Nach dem Entleervorgang wird die Hubvorrichtung soweit abgesenkt, daß die Behälter von der Aufnahmeeinrichtung wieder abgenommen werden können.Such lifting devices are used on garbage trucks both in the so-called side loaders and in the rear loaders. The garbage containers are lifted from the floor by means of these lifting devices and transported to the fill-in opening, where the containers are emptied by pivoting. After the emptying process, the lifting device is lowered to such an extent that the containers can be removed from the receiving device.
Die US 4,057, 156 beschreibt eine Hubvorrichtung mit einer umlaufenden Kette, die über ein Antriebszahnrad eines Hydraulikmotors geführt wird. An der Kette ist ein Schlitten mit einer Aufnahmeeinrichtung für Müllbehälter angebracht. Derartige Motoren sind jedoch aufwendig, störanfällig und teuer und benötigen eine komplizierte Steuereinrichtung. Die Antriebskette muß über mehrere Zahnräder und Umlenkräder geführt werden, wodurch ein entsprechend hoher konstruktiver Aufwand erforderlich ist.No. 4,057,156 describes a lifting device with a revolving chain which is guided over a drive gear of a hydraulic motor. A sled with a holding device for waste containers is attached to the chain. However, such motors are complex, prone to failure and expensive and require a complicated control device. The drive chain must be guided over several gears and deflection wheels, which means that a correspondingly high design effort is required.
Eine ähnliche Hubvorrichtung ist aus der DE-OS 24 12 096 bekannt. Eine umlaufende Kette wird durch eine elektromotorisch angetriebene Umlenkrolle bewegt. Der Antrieb kann auch mechanisch, hydraulisch oder pneumatisch erfolgen, wobei diese Antriebsmittel nicht näher erläutert werden.A similar lifting device is known from DE-OS 24 12 096. A rotating chain is driven by an electromotive driven pulley emotional. The drive can also be mechanical, hydraulic or pneumatic, these drive means not being explained in detail.
Die Schüttvorrichtung der DE 41 42 307 AI besitzt einen Linearantrieb für den Hubbalken, der einen druckmittelbetriebenen Getriebemotor mit einem Zahnritzel umfaßt, über das eine mit dem Schwenkbalken verbundene Duplexkette geführt ist.The pouring device of DE 41 42 307 AI has a linear drive for the walking beam, which comprises a pressure medium-operated gear motor with a toothed pinion, via which a duplex chain connected to the pivoting beam is guided.
In der EP 07 61 568 AI werden zwei Ausführungsformen einer Hubvorrichtung beschrieben, wonach entweder teleskopierbare Zug- Druckmittelzylinder oder Druck-Druckmittelzylinder eingesetzt werden, an deren Ende die Aufnahmeeinrichtung befestigt ist. Der Nachteil dieser Ausführung besteht darin, daß die Zylinder auf die volle Hubhöhe ausgefahren werden müssen.EP 07 61 568 AI describes two embodiments of a lifting device, according to which either telescopic tension-pressure medium cylinders or pressure-pressure medium cylinders are used, at the end of which the receiving device is attached. The disadvantage of this design is that the cylinders have to be extended to the full stroke height.
Aufgabe der Erfindung ist es, eine einfache, kompakte und wenig störanfällige Hubvorrichtung für Müllbehälter bereitzustellen.The object of the invention is to provide a simple, compact and less prone to failure lifting device for garbage containers.
Diese Aufgabe wird mit einer Hubvorrichtung gelöst, bei der der Antriebsmotor mindestens einen vertikal angeordneten Druckmittelmotor und zwei gegenüberliegend angeordnete Kolbenstangen umfaßt, die an ihrem freien Ende jeweils eine Umlenkrolle für das Seil oder die Kette tragen, das bzw. die mit seinen/ihren Enden an einem oder zwei ortsfesten Bauteilen befestigt ist.This object is achieved with a lifting device in which the drive motor comprises at least one vertically arranged pressure medium motor and two piston rods arranged opposite one another, each of which carries at its free end a deflecting roller for the rope or the chain, with its ends one or two fixed components is attached.
Druckmittelmotore wurden in der Vergangenheit häufig bei Hubkippvorrichtungen zum Entleeren von Müllbehältern eingesetzt und haben sich durch hohe Zuverlässigkeit ausgezeichnet. Gemäß einer ersten Ausführungsform handelt es sich bei dem Antriebsmotor um einen einzigen Druckmittelmotor, der einen Kolben mit zwei gegenüberliegenden Kolbenstangen aufweist. Die Enden des Seils oder der Kette können am Zylinder des Druckmittelmotors befestigt sein. Diese konstruktiven Merkmale besitzen im Zusammenwirken mit der erfindungsgemäßen Führung des Seils oder der Kette den Vorteil, daß bei einem Kolbenhub von beispielsweise einem Meter die am Seil oder der Kette befestigte Aufnahmeeinrichtung um den doppelten Weg, das heißt also um zwei Meter bewegt wird. Es wird dadurch auf einfache Weise eine Übersetzung erzielt, so daß die gesamte Baulänge des Druckmittelmotors entsprechend kurz ausgeführt werden kann.In the past, pressure medium motors were often used for lifting and tipping devices for emptying garbage containers and have stood out for their high reliability. According to a first embodiment, the drive motor is a single pressure medium motor which has a piston with two opposite piston rods. The ends of the rope or chain can be attached to the cylinder of the pressure medium motor. These constructive features, in cooperation with the guidance of the rope or chain according to the invention, have the advantage that with a piston stroke of, for example, one meter, the receiving device attached to the rope or chain is moved twice, that is to say by two meters. A translation is thereby achieved in a simple manner, so that the overall length of the pressure medium motor can be made correspondingly short.
Die Anordnung des Druckmittelmotors am Müllfahrzeug kann so gewählt werden, daß in der nach unten ausgefahrenen Stellung der Aufnahmeeinrichtung die Hubvorrichtung gegenüber dem Sammelbehälter des Müllfahrzeugs nicht nach oben vorsteht. Die Bauhöhe des Müllfahrzeugs wird somit durch die Hubvorrichtung nicht vergrößert, wie es z.T. bei den Vorrichtungen nach dem Stand der Technik der Fall ist.The arrangement of the pressure medium motor on the refuse collection vehicle can be selected such that the lifting device does not protrude upwards from the collection container of the refuse collection vehicle when the receiving device is in the downward position. The height of the garbage truck is therefore not increased by the lifting device, as is sometimes the case. is the case with the devices according to the prior art.
Der Druckmittelmotor hat den weiteren Vorteil, daß der Müllbehälter auf einfache Weise in jede beliebige Höhe hochgefahren werden kann, so daß die Hubvorrichtung an Fahrzeugen mit unterschiedlichen Einschüttöflrhungen zum Einsatz kommen kann.The pressure medium motor has the further advantage that the refuse container can be raised to any height in a simple manner, so that the lifting device can be used on vehicles with different openings.
Vorzugsweise ist der Kolben des Druckmittelmotors beidseitig mit Druckmittel beaufschlagbar. Dies bietet den Vorteil, daß nicht nur der Hubvorgang gezielt abläuft, sondern auch die Geschwindigkeit des Absenkvorgangs definiert eingestellt werden kann.The piston of the pressure medium motor can preferably be acted upon on both sides with pressure medium. This has the advantage that not only does the lifting process take place in a targeted manner, but the speed of the lowering process can also be set in a defined manner.
Die Vorteile eines Druckmittelmotors mit zwei Kolbenstangen bleiben auch bei der zweiten Ausführungsform erhalten, bei der zwei Druckmittelmotore mit jeweils einer Kolbenstange um 180° zueinander gedreht angeordnet sind. Die beiden Druckmittelmotore werden zylinderseitig benachbart zueinander angeordnet, so daß sich die beiden Kolbenstangen auf den abgewandten Seiten der Druckmittelmotore befinden. Während des Hub- bzw. Absenkvorgangs führen die Kolbenstangen eine gegenläufige Bewegung aus. Auf Grund der vertikalen Anordnung fährt eine Kolbenstange nach oben und die andere Kolbenstange nach unten aus. Beim Hochfahren und beim Herunterfahren der Aufnahmeeinrichtung braucht lediglich der Kolben des betreffenden Druckmittelmotors mit Druckmittel beaufschlagt werden. Der jeweils andere Kolben wird hierbei mitgeschleppt und drückt das in seinem Druckmittelmotor befindliche Druckmittel aus dem Zylinder heraus.The advantages of a pressure medium motor with two piston rods are also retained in the second embodiment, in which two pressure medium motors, each with a piston rod, are arranged rotated by 180 ° to one another. The two pressure medium motors are arranged adjacent to one another on the cylinder side, so that the two piston rods are located on the opposite sides of the pressure medium motors. During the lifting or lowering process the piston rods move in opposite directions. Due to the vertical arrangement, one piston rod extends upwards and the other piston rod extends downwards. When starting up and shutting down the receiving device, only the piston of the pressure medium motor in question needs to be pressurized with pressure medium. The other piston is dragged along and pushes the pressure medium in its pressure medium motor out of the cylinder.
Die Aufnahmeeinrichtung ist vorzugsweise in einer parallel zum Druckmittelmotor angeordneten Linearführung geführt. Diese Linearführung kann beispielsweise eine Schiene sein.The receiving device is preferably guided in a linear guide arranged parallel to the pressure medium motor. This linear guide can be a rail, for example.
Die Aufnahmeeinrichtung, an der ein oder mehrere Müllbehälter angeordnet werden können, kann gemäß einer weiteren Ausführungsform auch an den Seilen oder Ketten mehrerer Druckmittelmotore befestigt sein, die beispielsweise bei einem Hecklader an den beiden Außenseiten angeordnet sein können. Die Druckmittelmotore müssen in diesem Fall gleichzeitig dieselbe Bewegung ausführen.According to a further embodiment, the receiving device, on which one or more waste containers can be arranged, can also be attached to the ropes or chains of a plurality of pressure medium motors, which can be arranged on the two outer sides, for example, in a rear loader. In this case, the pressure medium motors must simultaneously perform the same movement.

Im Inneren des Druckmittelmotors 4 befindet sich der nicht dargestellte Kolben, an dem oben und unten jeweils eine Kolbenstange 6, 7 befestigt ist, die oben und unten aus dem Zylinder 5 herausragen. Sowohl an der unteren Kolbenstange 6 als auch an der oberen Kolbenstange 7 ist am freien Ende jeweils eine untere Umlenkrolle 8 bzw. eine oberen Umlenkrolle 9 befestigt. Über die Umlenkrollen wird eine Kette 10 geführt, deren Ende an den Befestigungspunkten 11 und 12 am Zylinder 5 des Druckmittelmotors 4 befestigt ist. In der hier gezeigten Darstellung befinden sich die Befestigungspunkte 11 und 12 jeweils am Ende des Zylinders 5.In FIG. 1, a carrier plate 3 is flanged to a rear wall or side wall 2 of a refuse collection vehicle 1, to which a pressure medium motor 4 is fastened in a vertical orientation. The cylinder 5 of the pressure medium motor 4 is fastened in the upper half of the carrier plate. Inside the pressure medium motor 4 is the piston, not shown, to which a piston rod 6, 7 is attached at the top and bottom, which protrude from the cylinder 5 at the top and bottom.

A chain 10 is guided over the deflection rollers, the end of which is attached to the fastening points 11 and 12 on the cylinder 5 of the pressure medium motor 4. In the illustration shown here, the fastening points 11 and 12 are each located at the end of the cylinder 5.
An der Kette 10 ist die Aufnahmeeinrichtung 13 befestigt, die nur schematisch dargestellt ist und in der Regel noch weitere Bauteile zur Aufnahme eines Müllbehälters umfaßt. Die Aufnahmeeinrichtung 13 wird in einer Schiene 14 geführt, die sich über die gesamte Länge der Trägerplatte 3 parallel zum Druckmittelmotor 4 erstreckt.On the chain 10, the receiving device 13 is fastened, which is only shown schematically and generally also comprises other components for receiving a waste container. The receiving device 13 is guided in a rail 14 which extends parallel to the pressure medium motor 4 over the entire length of the carrier plate 3.
In der Figur 1 ist die untere Position der Aufhahmeeinrichtung 13 dargestellt, in der der zu entleerende Müllbehälter mit der Aufnahmeeinrichtung zusammengebracht wird. Dementsprechend ist die untere Kolbenstange voll ausgefahren und die obere Kolbenstange 7 befindet sich bis auf ihr oberes Teilstück mit der Umlenkrolle 9 vollständig im Inneren des Zylinders 5.FIG. 1 shows the lower position of the receiving device 13, in which the refuse container to be emptied is brought together with the receiving device. Accordingly, the lower piston rod is fully extended and the upper piston rod 7, with the exception of its upper section with the deflection roller 9, is located completely inside the cylinder 5.
In der Figur 2 ist eine mittlere Hubposition dargestellt, bei der die obere Kolbenstange 7 und die untere Kolbenstange 6 in etwa gleicher Länge aus dem Zylinder 5 herausragen. Es ist deutlich zu sehen, daß der zurückgelegte Weg der Aufnahmeeinrichtung 13 nur mit dem halben Hubweg der Kolbenstangen 6 und 7 einhergeht.FIG. 2 shows a middle stroke position in which the upper piston rod 7 and the lower piston rod 6 protrude from the cylinder 5 in approximately the same length. It can be clearly seen that the path covered the receiving device 13 is only accompanied by half the stroke of the piston rods 6 and 7.
In der Figur 3 ist die obere Position dargestellt, in der die obere Kolbenstange 7 voll ausgefahren ist. Nur in Hubposition ragt die obere Kolbenstange 7 gegenüber der Oberkante des Müllfahrzeugs 1 hinaus.
