Description

Die Erfindung betrifft eine Hebevorrichtung, geeignet zur Anordnung auf einem Lastkraftfahrzeug zum Anheben und Entleeren von unterirdischen Abfallsammelbehältern nach dem Oberbegriff des Patentanspruchs 1 und einen unterirdischen Abfallsammelbehälter, um mit einer solchen Hebevorrichtung zusammenzuwirken, nach dem Oberbegriff des Anspruchs 7.The invention relates to a lifting device suitable for arrangement on a truck for lifting and emptying underground waste collecting containers according to the preamble of patent claim 1 and an underground waste collecting container to cooperate with such a lifting device according to the preamble of claim 7.

Unterirdische Abfallsammelbehälter mit einem Einwurfschacht werden immer häufiger eingesetzt, um die grossen Mengen an Hausabfällen einfach an einem zentralen Sammelplatz in den Gemeinden entsorgen zu können. Die unterirdischen Abfallsammelbehälter haben den Vorteil, dass die Abfälle von einem Deckel abgedeckt sind, auf welchem der Einwurfschacht angebracht ist. Um diese unterirdische Abfallsammelbehälter zu leeren, muss zunächst der Deckel vollständig angehoben werden, um den offenen Behälter freizugeben. Sodann wird der Behälter mit ausfahrbaren Gelenkarmen einer Hebevorrichtung an den Rändern gegriffen und aus der Grube angehoben, um in den Müllcontainer eines Müllsammelfahrzeugs geleert zu werden. Eine solche gattungsgemäße Hebevorrichtung ist beispielsweise aus EP-A-1 306 321 bekannt. In diesem Dokument wird ausführlich auf den früheren Stand der Technik NL-C-1 002 778 eingegangen und erwähnt, dass es nachteilig ist, ein seitliches Schienensystem mit Gabeln am Müllsammelfahrzeug vorzusehen, da das Fahrzeug dann sehr genau gegenüber dem zu leerenden Müllbehälter platziert werden muss. Die beiden Gelenkarmen der EP-A-1 306 321 sind schwenkbar im unteren Bereich des Müllsammelfahrzeugs befestigt, so dass sie nach unten ausgeschwenkt werden, um den offenen Behälter mit einem Rahmen zu fassen, und nach oben hochgeschwenkt werden, um den Behälter durch Kippen in den Müllcontainer des Müllsammelfahrzeugs zu leeren. In einer anderen Ausführungsform sind zwei Teleskopstangen vorgesehen (Fig. 9), welche ebenfalls im unteren Bereich des Müllsammelfahrzeugs schwenkbar gelagert sind.Underground waste collection bins with a chute are increasingly being used to simply dispose of the large quantities of household waste at a central collection point in the community. The underground waste collection container has the advantage that the waste is covered by a lid on which the insertion shaft is attached. In order to empty this underground waste collection container, the lid must first be raised completely to reveal the open container. The container is then gripped at the edges with extendable articulated arms of a lifting device and lifted out of the pit in order to be emptied into the refuse container of a refuse collection vehicle. Such a generic lifting device is, for example, from EP-A-1 306 321 known. This document details the prior art NL-C-1 002 778 received and mentioned that it is disadvantageous to provide a side rail system with forks on the refuse collection vehicle, since the vehicle must then be placed very precisely opposite the refuse container to be emptied. The two articulated arms of the EP-A-1 306 321 are pivotally mounted in the lower area of the refuse collection vehicle so that they can be swung down to hold the open container with a frame, and swiveled up to empty the container by tilting into the refuse container of the refuse collection vehicle. In another embodiment, two telescopic rods are provided ( Fig. 9 ), which are also pivotally mounted in the lower area of the refuse collection vehicle.

Die obige Hebevorrichtung hat den Nachteil, dass sie ausschliesslich für offene Abfallsammelbehälter eingesetzt werden kann. Ausserdem ist die Verteilung der auf die Gelenkarme wirkenden Kräfte ungünstig, so dass die Gelenkarme und die zur Bewegung benötigten pneumatischen Hubzylinder sehr robust ausgebildet sein müssen.The above lifting device has the disadvantage that it can only be used for open waste collection containers. In addition, the distribution of the the articulated arms are unfavorable forces, so that the articulated arms and the pneumatic lifting cylinders required for movement have to be very robust.

NL-C-1 002 778 offenbart einen unterirdische Abfallsammelbehälter gemäß dem Oberbegriff des Anspruchs 7. NL-C-1 002 778 discloses an underground waste collection container according to the preamble of claim 7.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Hebevorrichtung für einen Abfallsammelbehälter anzugeben, welche für das Anheben und Kippen von Abfallsammelbehältern samt Deckel und Einwurfschacht geeignet ist. Zudem soll eine bessere Verteilung der auf die Greifarme wirkenden Kräfte erreicht werden. Eine weitere Aufgabe der Erfindung ist es, ein unterirdischer Abfallsammelbehälter anzugeben, welcher geeignet ist, mit einer solchen Hebevorrichtung zusammenzuwirken.The present invention is based on the object of specifying a lifting device for a waste collection container which is suitable for lifting and tipping waste collection containers together with the lid and the insertion shaft. In addition, a better distribution of the forces acting on the gripping arms is to be achieved. Another object of the invention is to provide an underground waste collection container which is suitable for interacting with such a lifting device.

Diese Aufgaben werden durch eine Hebevorrichtung für ein Lastkraftfahrzeug mit den Merkmalen des Patentanspruchs 1 bzw. durch eine unterirdische Abfallsammelbehälter nach Patentanspruch 7 gelöst.These objects are achieved by a lifting device for a truck with the features of claim 1 or by an underground waste collection container according to claim 7.

Die Hebevorrichtung ist geeignet zur Anordnung auf einem Lastkraftfahrzeug zum Anheben und Entleeren von unterirdischen Abfallsammelbehältern und ist mit zwei parallelen teleskopisch ausfahrbaren, schwenkbar an einem Träger befestigten Auslegern versehen, welche je ein Kupplungswerkzeug zum lösbaren Kuppeln mit je einem Seitenrand eines Abfallsammelbehälters aufweisen.The lifting device is suitable for arrangement on a truck for lifting and emptying underground waste collection bins and is provided with two parallel telescopically extendable arms pivotably attached to a carrier, each of which has a coupling tool for releasable coupling, each with a side edge of a waste collection bin.

Dadurch, dass die teleskopisch ausfahrbaren Ausleger schwenkbar an dem auf- und abbewegbaren Träger angeordnet sind, können diese auch nicht exakt horizontal aufgestellten Abfallsammelbehälter erfassen und anheben. Dasselbe gilt natürlich auch für ansteigende Strassen, wodurch die Hebevorrichtung mit einem Lastkraftfahrzeug in einem spitzen Winkel zum horizontal aufgestellten Müllbehälter problemlos funktioniert. Erfindungsgemäss dient jedes Kupplungswerkzeug dazu, eine Kupplung mit je einem Balken zu bewirken, welche seitlich am oberen Rand des Abfallsammelbehälters auf gegenüberliegenden Seiten angeordnet sind. Ferner ist ein Aufzugmechanismus mit zwei parallelen, vertikalen Führungsschienen vorgesehen und ist der Träger zwischen den Führungsschienen angeordnet und längs diesen auf- und abbewegbar.Due to the fact that the telescopically extendable booms are pivotally arranged on the up and down movable carrier, they can also capture and raise waste collection containers that are not positioned exactly horizontally. The same naturally also applies to uphill roads, which means that the lifting device with a truck works without problems at an acute angle to the horizontally positioned waste container. According to the invention, each coupling tool serves to effect a coupling with one bar each, which are arranged laterally on the upper edge of the waste collection container on opposite sides. Furthermore, a Elevator mechanism provided with two parallel, vertical guide rails and the carrier is arranged between the guide rails and movable up and down along these.

Mit Vorteil ist das Kupplungswerkzeug von einem Elektromagneten ausgebildet. Andererseits kann das Kupplungswerkzeug auch mechanisch ausgebildet sein. Dazu kann das Kupplungswerkzeug ein Greifer sein, der vorzugsweise mit einem V-förmigen Schlitz versehen ist, welcher mit einem Kupplungsstift eines Abfallsammelbehälters zusammenwirkt. Zudem kann der Greifer U-förmig ausgebildet sein.The coupling tool is advantageously formed by an electromagnet. On the other hand, the coupling tool can also be designed mechanically. For this purpose, the coupling tool can be a gripper, which is preferably provided with a V-shaped slot, which interacts with a coupling pin of a waste collection container. In addition, the gripper can be U-shaped.

Ferner weist der unterirdische Abfallsammelbehälter, welcher mit einem oberen Rand und einem Deckel versehen ist, der mit einem Scharnier am Abfallsammelbehälter kippbar befestigt ist, wobei ein Einwurfschacht auf dem Deckel befestigt ist, vorteilhafterweise am oberen Rand seitlich zwei parallele Balken auf gegenüberliegenden Seiten auf und der Deckel ist auf beiden gegenüberliegenden Seiten je mit einem Rücksprung versehen, welcher den Balken entspricht, wobei die Balken dazu vorgesehen sind, um mit den Kupplungswerkzeugen der Hebevorrichtung nach einem der Ansprüche 1 bis 6 zusammenzuwirken.Furthermore, the underground waste collection container, which is provided with an upper edge and a lid, which is pivotally attached to the waste collection container with a hinge, an insertion slot being attached to the lid, advantageously on the upper edge laterally, two parallel bars on opposite sides and the Lid is provided on both opposite sides with a recess, which corresponds to the bar, the bars being provided to cooperate with the coupling tools of the lifting device according to one of claims 1 to 6.

Auf dem Deckel 2 ist ein Einwurfschacht 4 befestigt, durch welchen Abfallsäcke in den Abfallsammelbehälter 1 eingeworfen werden können. Am oberen Rand 5 des Abfallsammelbehälters 1 sind seitlich zwei parallele Balken 6 auf gegenüberliegenden Seiten angeordnet. Ferner sind zwei parallele teleskopisch ausfahrbare Ausleger 7 mit schwenkbar um eine Achse 8 gelagerten Kupplungswerkzeugen 9 an ihren freien Enden in einer Teilansicht erkennbar. Wie in Figur 2 erkennbar, ist der Deckel 2 auf beiden gegenüberliegenden Seiten je mit einem Rücksprung 11 versehen, welcher den Balken 6 entspricht, so dass der Deckel 2 bei angekuppelten Auslegern 7 geöffnet bzw. gekippt werden kann. Die Kupplungswerkzeuge 9 können mit starken Elektromagneten (nicht dargestellt) versehen sein oder auch eine rein mechanische Kupplung mit den Balken 6 bewirken.In the Figures 1 and 2 is an underground waste collection container 1 with a lid 2 which is hinged on the back with a hinge 3 on the waste collection container. On the cover 2, an insertion chute 4 is fastened, through which waste bags can be thrown into the waste collection container 1. At the upper edge 5 of the waste collection container 1 are two parallel bars on the side 6 arranged on opposite sides. Furthermore, two parallel telescopically extendable booms 7 with coupling tools 9 pivotably mounted about an axis 8 can be seen at their free ends in a partial view. As in Figure 2 recognizable, the cover 2 is provided on both opposite sides with a recess 11, which corresponds to the bar 6, so that the cover 2 can be opened or tilted when the arms 7 are coupled. The coupling tools 9 can be provided with strong electromagnets (not shown) or can also effect a purely mechanical coupling with the bars 6.

In den Figuren 3 bis 6 ist eine Hebevorrichtung 15 mit vertikalen Führungsschienen 16 auf der Seite eines Müllcontainers 17 eines Lastkraftfahrzeuges 18 ersichtlich. Zwischen den Führungsschienen 16 ist ein Träger 20 auf- und abbewegbar befestigt. An jedem Ende des Trägers 20 ist je einer der teleskopisch ausfahrbaren Ausleger 7 drehbar befestigt.In the Figures 3 to 6 is a lifting device 15 with vertical guide rails 16 on the side of a dumpster 17 of a truck 18 can be seen. Between the guide rails 16, a carrier 20 is fastened so that it can be moved up and down. At each end of the carrier 20, one of the telescopic booms 7 is rotatably attached.

In den Figuren 7 und 8 ist der Abfallsammelbehälter 1 mit einem mechanischen Hebelmechanismus 22 gezeigt, der einen U-förmigen Rahmen 23 aufweist, welcher seitlich zum Abfallsammelbehälter 1 an je einer Schwenkachse 24 (nur auf der Vorderseite ersichtlich) kippbar gelagert ist. An den freien Enden des U-förmigen Rahmens 23 ist je ein Kupplungsstift 25 mit einem kegelförmigen Senkkopf 26 vorgesehen. An der Basis 27 des U-förmigen Rahmens 23 ist mittig ein kleiner Hubzylinder 28 vorgesehen, der im ausgezogenen Zustand den Rahmen 23 gegen den Rand 5 des Abfallsammelbehälters 1 drückt, so dass die Kupplungsstifte 25 im Balken 6 versenkt sind (Fig. 7). Wenn der Hubzylinder 28 zusammengezogen wird (Fig. 8), stehen die Kupplungsstifte 25 aus den Balken 6 hervor.In the Figures 7 and 8 the waste collection container 1 is shown with a mechanical lever mechanism 22 which has a U-shaped frame 23 which is tiltably mounted laterally to the waste collection container 1 on a respective pivot axis 24 (only visible on the front). At the free ends of the U-shaped frame 23, a coupling pin 25 with a conical countersunk head 26 is provided. A small lifting cylinder 28 is provided in the center of the base 27 of the U-shaped frame 23, which in the extended state presses the frame 23 against the edge 5 of the waste collection container 1, so that the coupling pins 25 are sunk in the beam 6 ( Fig. 7 ). When the lift cylinder 28 is contracted ( Fig. 8 ), the coupling pins 25 protrude from the bars 6.

Wie in Figur 9 ersichtlich, können nun die teleskopisch ausfahrbaren Ausleger 7 mit den Kupplungswerkzeugen 9 in die Kupplungsstifte 25 eingeklinkt werden, um den gesamten Abfallsammelbehälter 1 anzuheben oder zu versenken.As in Figure 9 can be seen, the telescopically extendable boom 7 with the coupling tools 9 can now be latched into the coupling pins 25 in order to raise or lower the entire waste collection container 1.
