Description

Die Erfindung betrifft eine Schnellwechselvorrichtung für an dem Hubgerüst eines Trägerfahrzeuges zu verlagernde Anbaugeräte.The invention relates to a quick-change device for attachments to be moved on the mast of a carrier vehicle.

Durch die DE-OS 39 24 313 ist ein Adapter für Frontladeranbaugeräte bekannt, mit dem ein Werkzeug, wie beispielsweise eine Schaufel oder eine Gabel an einen Fahrzeugkörper gekoppelt werden kann. Der Adapter kann für die Koppelung von Werkzeugen unterschiedlichster Art und Größe verwendet werden. Der Adapter beinhaltet Seitenkonsolen sowie eine mittlere Konsole, die durch einen Stützrahmen starr miteinander verbunden sind und in Geradeausrichtung mit einem Hubarmpaar und einem vom Fahrzeugkörper hervorstehenden Dreharm drehbar verbunden sind. Nachteile dieses Adapters werden im wesentlichen darin gesehen, daß hier durch den Einsatz vielfältiger Bauelemente eine verhältnismäßig aufwendige Konstruktion geschaffen wird, die sich letztendlich in einer nicht unbeträchtlichen Gewichtserhöhung bemerkbar macht.From DE-OS 39 24 313 an adapter for front loader attachments is known, with which a tool, such as a shovel or fork, can be coupled to a vehicle body. The adapter can be used for coupling tools of various types and sizes. The adapter includes side brackets and a middle bracket which are rigidly connected to each other by a support frame and are rotatably connected in a straight line with a pair of lifting arms and a rotating arm protruding from the vehicle body. Disadvantages of this adapter are essentially seen in the fact that the use of diverse components creates a relatively complex construction, which ultimately results in a not inconsiderable increase in weight.

Das dem Erfindungsgegenstand zugrunde liegende Ziel wird darin gesehen, bei einer Gewichtsreduzierung gegenüber dem St.d.T. eine möglichst einfach bauende Schnellwechselvorrichtung zu konzipieren, deren wesentliche Betätigungselemente in geschützter Form vorgesehen sind.The goal underlying the subject matter of the invention is seen in a weight reduction compared to the St.d.T. to design a quick-change device that is as simple as possible, the essential actuating elements of which are provided in a protected form.

Dieses Ziel wird erfindungsgemäß bei einer Schnellwechselvorrichtung für an dem Hubgerüst eines Trägerfahrzeuges zu verlagernde Anbaugeräte dahingehend erreicht, daß das Hubgerüst aus zwei im wesentlichen parallel zueinander verlaufenden Hubarmen gebildet ist, deren eine Enden am Trägerfahrzeug gelagert sind und deren andere Enden zwischen sich einen als Traverse ausgebildeten Hohlkörper aufnehmen, an welchem ein Zuglenkerpaar gelenkig gelagert ist, dessen freies Ende mit Elementen des jeweiligen Anbaugerätes verbindbar ist und im Bereich seiner Erstreckung mit mindestens einer gelenkig gelagerten Zugstange zusammenwirkt, die wiederum mit weiteren im Bereich des Hubgerüstes vorgesehenen Bauteilen verbunden ist, und wobei die Verriegelungseinrichtung zur Arretierung des Hubgerüstes am jeweiligen Anbaugerät innerhalb des Hohlkörpers vorgesehen ist.This aim is achieved according to the invention in a quick-change device for attachments to be relocated to the lifting frame of a carrier vehicle in such a way that the lifting frame is formed from two essentially parallel lifting arms, one end of which is mounted on the carrier vehicle and the other ends of which are designed as traverses Take up the hollow body on which a pair of tension links is articulated, the free end of which can be connected to elements of the respective attachment and, in the area of its extension, interacts with at least one articulated tie rod, which in turn is connected to other components provided in the area of the mast, and the Locking device for locking the mast on the respective attachment is provided within the hollow body.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the invention can be found in the subclaims.

Mit der rohrförmig ausgebildeten Traverse, die vorzugsweise im Bereich der Drehachse des jeweiligen Anbaugerätes vorgesehen ist, werden folgende wesentliche Funktionen erfüllt:

  • das tragende Teil des Hubgerüstes ist fest eingeschweißt,
  • innerhalb der Rohrtraverse werden sowohl der Verriegelungszylinder als auch die Verriegelungsbolzen samt Führungen und Dichtelemente aufgenommen,
  • außerhalb der Rohrtraverse wird auf dem Außendurchmesser das Zuglenkerpaar nahe der Zugstange gelagert.
The following essential functions are fulfilled with the tubular crossmember, which is preferably provided in the area of the axis of rotation of the respective attachment:
  • the load-bearing part of the mast is welded in,
  • The locking cylinder as well as the locking bolts, including guides and sealing elements, are accommodated within the tubular crossbeam.
  • outside of the tubular traverse, the pair of tension links is mounted on the outside diameter near the tie rod.

Die Bewegung des Anbaugerätes wird durch das außerhalb der Rohrtraverse angeordnete Zugstangenlenkerpaar herbeigeführt, wobei diese Bewegung durch die starr mit den Hubarmen verbundene Traverse nicht mitgemacht wird. Infolge des konstruktiven Aufbaus kann gegenüber herkömmlichen Schnellwechseleinrichtungen eine beträchtliche Gewichtsersparnis erreicht werden, wobei infolge der geometrischen Verhältnisse der einzelnen Bauteile zueinander nur verhältnismäßig geringe Gewichte bewegt werden und ihre Lage verändern müssen. Somit wird ein verbesserter Wirkungsgrad bei lediglich geringer Schwerpunktverlagerung realisiert.The movement of the attachment is brought about by the pair of tie rods arranged outside the tubular crossbar, this movement not being carried out by the crossbar rigidly connected to the lifting arms. As a result of the structural design, considerable weight savings can be achieved compared to conventional quick-change devices, with only relatively small weights being moved due to the geometric relationships of the individual components and having to change their position. This results in an improved efficiency with only a slight shift in the center of gravity.

Infolge der Lagerung des Zugstangenlenkerpaares unmittelbar auf der Rohrtraverse kann das Zugstangenlenkerpaar nahe der Zugstange angeordnet werden, wobei es für den Fahrer des Trägerfahrzeuges beim Wechselvorgang gut einsehbar ist. Die Verriegelung wird hydraulisch betätigt, wobei die notwendigen hydraulischen Leitungen am Übergang des Hubgerüstes in den Bereich der Schnellwechselvorrichtung fest installiert werden können, da die Traverse keine Relativbewegung durchführt. Der Verriegelungszylinder, die Verriegelungsbolzen sowie die damit zusammenwirkenden Führungen und Dichtungen sind absolut geschützt innerhalb der Traverse angeordnet und sind somit den normalerweise auftretenden Verschmutzungen oder Beschädigungen nicht mehr ausgesetzt.As a result of the mounting of the pair of tie rod links directly on the tubular traverse, the pair of tie rod links can be arranged near the tie rod, it being easy to see for the driver of the carrier vehicle during the changing process. The locking mechanism is actuated hydraulically, and the necessary hydraulic lines can be permanently installed at the transition of the mast into the area of the quick-change device, since the traverse does not perform any relative movement. The locking cylinder, the locking bolts and the guides and seals that interact with them are arranged absolutely protected inside the crossmember and are therefore no longer exposed to the soiling or damage that normally occurs.

Figur 1 zeigt das Hubgerüst 1 samt schaufelförmigem Anbaugerät 2 eines nicht weiter dargestellten Trägerfahrzeuges. Das Hubgerüst 1 wird gebildet aus zwei Hubarmen 3, die im wesentlichen parallel zueinander angeordnet sind, deren eine Enden am nicht weiter dargestellten Trägerfahrzeug gelagert sind. Die anderen Enden 4 nehmen eine rohrförmig ausgebildete Traverse 5 zwischen sich auf, die in Figur 3 näher dargestellt ist. An der Rohrtraverse 5 greift ein Zugstangenlenkerpaar 6 an, das im Bereich seines freien Endes 7 mit bolzenförmigen Ansätzen 8 versehen ist, die in entsprechende Augen 9 des schaufelförmigen Anbaugerätes 2 eingreifen. Im Bereich seiner Erstreckung ist zwischen dem Zugstangenlenkerpaar 6 eine Zugstange 10 gelenkig gelagert, die mit einem weiteren Hebel 11 verbunden ist, an dessen freien Ende ein nicht weiter dargestellter Zylinder (Kippzylinder) angreift. Dieser Hebel 11 weist wiederum einen Schwenkpunkt 12 auf, der über einen weiteren Hebel 13 zwischen den Hubarmen 3 des Hubgerüstes 1 gelagert ist. Die Traverse 5 ist hierbei in der Drehachse 14 des Anbaugerätes 2 stationär, d.h. nicht verdrehbar, angeordnet.Figure 1 shows the mast 1 together with a shovel-shaped attachment 2 of a carrier vehicle, not shown. The lifting frame 1 is formed from two lifting arms 3, which are arranged essentially parallel to one another, one ends of which are mounted on the carrier vehicle (not shown). The other ends 4 take a tubular cross member 5 between them, which is shown in more detail in FIG. A pair of tie rod links 6, which is provided in the region of its free end 7 with bolt-shaped lugs 8, which engage in corresponding eyes 9 of the shovel-shaped attachment 2, acts on the tubular crossbeam 5. In the area of its extension, a tie rod 10 is articulated between the tie rod pair 6, which is connected to a further lever 11, at the free end of which a cylinder (tilt cylinder), not shown, acts. This lever 11 in turn has a pivot point 12 which is mounted via a further lever 13 between the lifting arms 3 of the mast 1. The cross member 5 is stationary in the axis of rotation 14 of the attachment 2, i.e. not rotatable, arranged.

Figur 2 zeigt als Teildarstellung ausschließlich das Hubgerüst 1 mit den Hubarmen 3, dem Zugstangenlenkerpaar 6, der Traverse 5, dem Zuglenker 10, den bolzenförmigen Ansätzen 8 sowie den Hebeln 11 und 13. Ferner erkennbar ist der Lagerbereich 15, an welchem das Hubgerüst 1 mit dem nicht weiter dargestellten Trägerfahrzeug verbindbar ist.Figure 2 shows a partial view of the mast 1 with the lifting arms 3, the pair of tie rods 6, the crossbar 5, the link 10, the bolt-shaped lugs 8 and the levers 11 and 13. Furthermore, the bearing area 15, on which the mast 1 with the carrier vehicle, not shown, can be connected.

Figur 3 zeigt als Teildarstellung die rohrförmig ausgebildete Traverse 5, die in ihrem Innenbereich 16 mit folgenden Bauteilen bestückt ist: einem Verriegelungszylinder 17, Verriegelungsbolzen 18,19, Kolbenstangen 20,21, Führungen 22,23 für die Verriegelungsbolzen 18,19 sowie O-Ringe 24,25,26,27 als Dichtelemente zwischen den Führungen 22,23 und den Verriegelungsbolzen 18,19. Die Verriegelungsbolzen 18,19 sind im Bereich ihrer freien Enden 28,29 angeschrägt ausgebildet, um auf diese Art und Weise leichter in die korrespondierenden Ausnehmungen des jeweiligen Anbaugerätes 2 einführbar zu sein.Figure 3 shows a partial representation of the tubular crossmember 5, which is equipped in its inner region 16 with the following components: a locking cylinder 17, locking bolts 18,19, piston rods 20,21, guides 22,23 for the locking bolts 18,19 and O-rings 24, 25, 26, 27 as sealing elements between the guides 22, 23 and the locking bolts 18, 19. The locking bolts 18, 19 are in the area their free ends 28, 29 are chamfered, in order to be easier to insert into the corresponding recesses of the respective attachment 2 in this way.

Am Außendurchmesser 30 der Traverse 5 sind etwa auf halber Höhe zwei Lagerbereiche 31,32 vorgesehen, die zur Aufnahme des Zuglenkerpaares 6 dienen. Die Traverse 5 ist, wie bereits angesprochen, in der Drehachse 14 des hier nicht weiter dargestellten Anbaugerätes 2 vorgesehen, wobei die Traverse 5 jedoch nicht verdrehbar ist. Demzufolge kann der Hydraulikanschluß 33 an einer bestimmten Stelle 34 der Traverse 5 ebenfalls stationär vorgesehen werden. Angedeutet sind die Hydraulikleitungen 35 und 36 zur Zufuhr des entsprechenden Druckmediums.On the outer diameter 30 of the crossmember 5, two bearing areas 31, 32 are provided approximately halfway up, which serve to accommodate the pair of tension links 6. As already mentioned, the crossmember 5 is provided in the axis of rotation 14 of the attachment 2 (not shown further here), but the crossmember 5 cannot be rotated. Accordingly, the hydraulic connection 33 can also be provided stationary at a specific point 34 of the crossmember 5. The hydraulic lines 35 and 36 for supplying the corresponding pressure medium are indicated.
