Description

Kupplungseinrichtung für ein Hebewerkzeug  Coupling device for a lifting tool
Die Erfindung betrifft eine Kupplungseinrichtung für ein Hebewerkzeug nach dem Oberbegriff des Patentanspruchs 1 . The invention relates to a coupling device for a lifting tool according to the preamble of patent claim 1.
STAND DER TECHNIK STATE OF THE ART
Aus DE-A-39 15 580 ist es bekannt, an einem Behälter zur Abfallentsorgung einen Schliessmechanismus für Entleerungsklappen vorzusehen, bei welchem ein ers- tes, mit der Behälterwandung fest verbundenes Kupplungsstück und ein zweites, als Zugstange ausgebildetes Kupplungsstück zur Betätigung der Entleerungsklappen vorzusehen. Das erste Kupplungsstück besteht aus einer Buchse mit einem oberen flanschformigen Rand, die zentrisch auf der Oberseite des Behälters angeordnet ist. Diese Buchse dient als Führungsbuchse für das zweite als Zug- stange ausgebildete Kupplungsstück. Auch das zweite Kupplungsstück weist einen oberen flanschformigen Rand auf. Ein solcher Schliessmechanismus ist heutzutage an den gängigen Behältern zur Abfallentsorgung vorgesehen. In diesem Patentdokument ist ferner eine Kupplungseinrichtung beschrieben, welche Haken aufweist, welche unter die flanschformigen Ränder des ersten und des zweiten Kupplungsstück über den Umfang verteilt eingreifen. Jeder Haken wird mittels einer hydraulischen Kolben-Zylinder-Einheit geöffnet bzw. geschlossen. Um die Zugstange an dem flanschformigen Rand anzuheben, ist eine hydraulische Kolben-Zylinder-Einheit vorgesehen, welche sich in Längsrichtung zur Zugstange erstreckt. Um die Zugstange in ihrer vollen Länge anzuheben, muss somit die Kupplungseinrichtung mindestens zweimal die Länge der Zugstange haben. Um zu verhindern, dass der Haken in der Nut des unteren Kupplungsstück verhakt bleibt und damit an einer Ausschwenkbewegung gehindert wird, sind zwei Verriegelungshebel vorgesehen, welche über Widerlager bildende Vorsprünge eines Joches für die oberen Haken greifen. From DE-A-39 15 580 it is known to provide on a container for waste disposal a closing mechanism for emptying flaps, in which a first, firmly connected to the container wall coupling piece and a second, designed as a pull rod coupling piece for actuating the emptying flaps provide. The first coupling piece consists of a bushing with an upper flanschformigen edge, which is arranged centrally on top of the container. This bushing serves as a guide bushing for the second coupling piece designed as a tension rod. Also, the second coupling piece has an upper flanschformigen edge. Such a closing mechanism is nowadays provided on the common containers for waste disposal. In this patent document, a coupling device is further described, which has hooks which engage under the flange-shaped edges of the first and the second coupling piece distributed over the circumference. Each hook is opened or closed by means of a hydraulic piston-cylinder unit. In order to lift the pull rod on the flange-shaped edge, a hydraulic piston-cylinder unit is provided, which extends in the longitudinal direction of the pull rod. In order to lift the drawbar in its full length, thus the coupling device must have at least twice the length of the drawbar. In order to prevent the hook remains hooked in the groove of the lower coupling piece and thus prevented from swiveling out, two locking levers are provided which engage over abutment-forming projections of a yoke for the upper hook.
Die obige Kupplungseinrichtung hat den Nachteil, dass jeder Haken von einer einzelnen Kolben-Zylinder-Einheit betätigt wird und Verriegelungshebel notwendig sind, um ein sicheres Öffnen der unteren Haken zu gewährleisten. Ferner weist diese Kupplungseinrichtung eine grosse Bauhöhe auf, was ein Manipulieren und Andocken an das als Pilz ausgebildete Kupplungsstück erschwert. AUFGABE DER ERFINDUNG The above coupling device has the disadvantage that each hook is actuated by a single piston-cylinder unit and locking lever necessary are to ensure a safe opening of the lower hooks. Furthermore, this coupling device has a large overall height, which makes it difficult to manipulate and dock on the coupling designed as a mushroom. OBJECT OF THE INVENTION
Es ist nun Aufgabe der vorliegenden Erfindung, eine Kupplungseinrichtung anzugeben, welche eine einfachere und schnellere Handhabung ermöglicht. GEGENSTAND DER ERFINDUNG It is an object of the present invention to provide a coupling device which allows easier and faster handling. SCOPE OF THE INVENTION
Diese Aufgabe wird durch eine Kupplungseinrichtung für ein Hebewerkzeug mit den Merkmalen des Patentanspruchs 1 gelöst. Die erfindungsgemässe Kupplungseinrichtung hat den grossen Vorteil, dass die Klemmzange mittels eines Verschlusselementes in die Klemmposition gebracht wird und somit keine Nut unterhalb der flanschförmigen Rand des Kupplungsstückes mehr benötigt wird und gleichzeitig eine Sicherung vorhanden ist, welche verhindert, dass die Klemmzange bei weiteren Manipulationen unbeabsichtigt geöffnet wird. This object is achieved by a coupling device for a lifting tool having the features of patent claim 1. The inventive coupling device has the great advantage that the clamping forceps is brought by means of a closure element in the clamping position and thus no groove below the flange-shaped edge of the coupling piece is more needed and at the same time a backup is present, which prevents the clamp open unintentionally in further manipulations becomes.

Der Längsschlitz 6 an der Klemmbacke 2 ist entlang den Rändern mit je einer Gleitschiene 7 aus gehärtetem Stahl versehen (siehe Fig. 2). Die Klemmbacken 2 und 3 sind im oberen Bereich über je ein Scharnier 8 drehbeweglich mit einem Verbindungsstück 10 miteinander verbunden. Auf der Aussenseite der Klemmbacken 2 und 3 sind im unteren Bereich abgewinkelte Kulissen 12 vorgesehen, wobei an den inneren Rändern der Klemmbacken 2 und 3 zusätzlich je eine Klemmplatte 13 vorgesehen ist. In Figur 2 ist die Klemmzange 1 in der geöffneten Position gezeigt, wobei auf den Gleitschienen 7 ein zweites Kupplungselement 15 nach oben und unten hin- und herverfahrbar angeordnet ist. Dieses zweite als Gleithaken ausgebildete Kupplungselement 15 weist eine durchgehende Bohrung 16 mit auf beiden Seiten eine Buchse 17 aus Messing auf. Ferner sind vier Schmiernippel 18 vorgesehen, um den Gleithaken 15 mit einer automatischen Schmierung über nicht-dargestellte Ölleitungen zu versehen. In Figur 3 ist ein Verschlussmittel 20 gezeigt, welches mit den Kulissen 12 und den Klemmplatten 13 der Klemmbacken 2 und 3 zusammenwirkt. Das Verschlussmittel 20 hat zwei gebördelte Randstücke 21 , auf deren Innenseite je eine winkelförmige Gleitkufe 22 vorgesehen ist. Gegenüberliegend zur Gleitkufe 22 ist ein halbkreiszylindrisches Führungsteil 23 vorgesehen, so dass zwischen diesen beiden eine Führungsnut 24 gegeben ist. Am unteren Bereich ist ein Schlitz 26 durch zwei gebördelte Randstücke 27 gebildet, welche je mit einem Verstärkungsteil 28 versehen ist. Beim Schliessen der Klemmzange 1 über die Kulissen 12 wird der Schlitz 26 des Verschlussmittels 20 über die Klemmplatten 13 geschoben, so dass das Verschlussmittel 20 die beiden Klemmbacken 2 und 3 arretiert. FIG. 1 shows a clamping tongs 1 as the first coupling element in the clamping position, which has two similarly designed clamping jaws 2 and 3. The jaws 2 and 3 are formed as U-profiles made of steel and have in the corners 4 each have an L-shaped clamping piece 5. Furthermore, the jaws 2 and 3 are provided with a closed longitudinal slot 6. The longitudinal slot 6 on the jaw 2 is provided along the edges, each with a slide rail 7 made of hardened steel (see Fig. 2). The jaws 2 and 3 are rotatably connected to each other in the upper region via a respective hinge 8 with a connecting piece 10. On the outside of the jaws 2 and 3 angled scenes 12 are provided in the lower region, in addition to the inner edges of the jaws 2 and 3 each a clamping plate 13 is provided. In Figure 2, the clamping pliers 1 is shown in the open position, wherein on the slide rails 7, a second coupling element 15 is arranged back and forth herverfahrbar up and down. This second designed as a sliding hook coupling element 15 has a through hole 16 with on both sides of a bushing 17 made of brass. Further, four grease nipples 18 are provided to provide the slide hook 15 with automatic lubrication via unillustrated oil lines. In Figure 3, a closure means 20 is shown, which cooperates with the scenes 12 and the clamping plates 13 of the jaws 2 and 3. The closure means 20 has two flanged edge pieces 21, on the inside of each an angled runner 22 is provided.

At the bottom of a slot 26 is formed by two flanged edge pieces 27, which is each provided with a reinforcing member 28. When closing the clamping pliers 1 on the scenes 12, the slot 26 of the closure means 20 is pushed over the clamping plates 13, so that the closure means 20, the two jaws 2 and 3 locked.
In Figur 4 ist das zweite Kupplungselement oder der Gleithaken 15 näher darge- stellt. Wie ersichtlich sind zwei parallele Nuten 31 vorgesehen, welche je zwei Messingplatten 32 aufweisen, welche auf den Gleitschienen 7 aufliegen (siehe Fig. 2). Ferner ist ein Klemmteil 33 mit zwei Fingern 34 und einem diesen gegenüberliegenden Gegenstück 35 vorgesehen. Das Klemmteil 33 ist auf der anderen Seite des Längsschlitzes 6 vorgesehen, so dass der Gleithaken 15 stets auf den Gleitschienen 7 gehalten wird. FIG. 4 shows the second coupling element or the sliding hook 15 in more detail. As can be seen, two parallel grooves 31 are provided, each having two brass plates 32 which rest on the slide rails 7 (see Fig. 2). Further, a clamping member 33 is provided with two fingers 34 and a counterpart 35 opposite this. The clamping part 33 is provided on the other side of the longitudinal slot 6, so that the sliding hook 15 is always held on the slide rails 7.
In Figur 5 ist ein Grundgestell 40 gezeigt, welches dazu dient, die Klemmzange 1 mit dem Gleithaken 15 lose zu umfassen. Es weist einen Boden 41 mit einem kreisförmigen Zentrierungsring 42 auf, welcher dazu dient, das pilzförmige Kupp- lungsstück des - hier nicht dargestellten - Behälters für Abfälle zu umfassen. Ferner weist das Grundgestell 40 zwei Seitenwände 43 und 44 auf, welche spiegelbildlich ausgebildet sind und je einen nierenförmigen Ausschnitt 45 und einen gebördelten Längsrand 46 aufweisen. Ferner weisen die Seitenwände 43 und 44 je eine Bohrung 47 mit einer Verstärkungsplatte 48 auf. Die Seitenwände 43 und 44 sind oben über einen Deckel 49 miteinander fest verbunden. Figur 6 zeigt einen Hebelarm 50, welcher im Grundgestell 40 gleitend befestigt ist und dazu dient, den Gleithaken 15 im Längsschlitz 6 der Klemmzange 1 auf- und abzubewegen. Dieser Hebelarm 50 weist zwei Seitenwangen 51 und 52 auf, welche spiegelbildlich ausgebildet sind und je eine kreissektorförmige Führungsnut 53 aufweisen. Auf der Rückseite sind die beiden Seitenwangen 51 und 52 von einer wannenförmigen Rückwand 54 zusammengehalten. Auf der Vorderseite ist eine Verbindungsstange 55 mit Muttern 56 an den Seitenwangen 51 und 52 befestigt. Diese Verbindungsstange 55 dient zur Befestigung des Gleithakens 15. Figur 7 zeigt zwei identische Kolben-Zylinder-Einheiten 61 , welche je zur Betätigung des Verschlussmittels 20 vorgesehen sind. Ferner sind zwei identische Kolben-Zylinder-Einheiten 62 gezeigt, welche für die Betätigung des Hebelarms 50 dienen. Des Weiteren ist ein Tragzylinder 63 vorgesehen, welcher an der Klemmzange 1 befestigt wird, um den von dieser in der Klemmposition gehaltenen Behälter hochheben zu können. FIG. 5 shows a base frame 40, which serves to loosely cover the clamping tongs 1 with the sliding hook 15. It has a base 41 with a circular centering ring 42, which serves to cover the mushroom-shaped coupling piece of the waste container (not shown here). Furthermore, the base frame 40 has two side walls 43 and 44, which are formed in mirror image and each have a kidney-shaped cutout 45 and a beaded longitudinal edge 46. Furthermore, the side walls 43 and 44 each have a bore 47 with a reinforcing plate 48. The side walls 43 and 44 are fixedly connected together above a cover 49 with each other. Figure 6 shows a lever arm 50 which is slidably mounted in the base frame 40 and serves to move the slide hook 15 up and down in the longitudinal slot 6 of the clamping jaw 1. This lever arm 50 has two side walls 51 and 52, which are formed in mirror image and each have a circular sector-shaped guide groove 53. On the back, the two side walls 51 and 52 are held together by a trough-shaped rear wall 54. On the front side, a connecting rod 55 with nuts 56 is attached to the side cheeks 51 and 52. This connecting rod 55 serves for fastening the sliding hook 15. FIG. 7 shows two identical piston-cylinder units 61, which are each provided for actuating the locking means 20. Furthermore, two identical piston-cylinder units 62 are shown, which serve for the actuation of the lever arm 50. Furthermore, a support cylinder 63 is provided, which is fastened to the clamping tongs 1 in order to be able to lift the container held by this in the clamping position.
Figur 8 zeigt nun die Kupplungseinrichtung 80 als Zusammenbau der Klemmzange 1 mit dem Gleithaken 15 im Grundgestell 40 und die Befestigung des Hebelarms 50 zum Gleithaken 15. FIG. 8 now shows the coupling device 80 as an assembly of the clamping tongs 1 with the sliding hook 15 in the base frame 40 and the attachment of the lever arm 50 to the sliding hook 15.
Aus den Figuren 9 und 10 ist der Bewegungsablauf von der geöffneten Position der Klemmzange 1 zur geschlossenen oder Klemmposition der Klemmzange 1 erkennbar. Ebenfalls sind hier der Pilz 70 ersichtlich, welcher den Behälter trägt, und die Pilzstange 71 mit dem Pilzkopf 72, welche Stange über Drahtseile oder dergleichen mit den Entleerungsklappen des Behälters verbunden ist. From Figures 9 and 10, the movement from the open position of the clamping tongs 1 to the closed or clamping position of the clamping tongs 1 can be seen. Also visible here are the mushroom 70 which carries the container and the mushroom rod 71 with the mushroom head 72, which rod is connected by wire ropes or the like to the emptying flaps of the container.
Aus den Figuren 1 1 und 12 ist ferner der Bewegungsablauf des Hebelarms 50 und des Gleithakens 15 ersichtlich. Durch die exzentrische Lagerung des Hebelarms 50 wird eine Übersetzung gebildet, so dass der Gleithaken 15 mit einer Hublänge der Kolben-Zylindereinheit 62, welche die Hälfte der Hublänge der Zugstange beträgt, über die gesamte Länge der Gleitschienen 7 bewegt werden kann. Das Übersetzungsverhältnis ist somit 1 :2. Durch eine andere Ausbildung des Hebelarms 50 können natürlich auch andere Übersetzungsverhältnisse gebildet werden. From the figures 1 1 and 12, the movement of the lever arm 50 and the sliding hook 15 is also apparent. By the eccentric mounting of the lever arm 50, a translation is formed, so that the sliding hook 15 with a stroke length of the piston-cylinder unit 62, which is half the stroke length of the drawbar, over the entire length the slide rails 7 can be moved. The gear ratio is thus 1: 2. Of course, other gear ratios can be formed by a different design of the lever arm 50.
