Description
Die Erfindung betrifft ein Anbauwerkzeug für Baumaschinen mit einer Aufnahme, über die das Anbauwerkzeug mit einem Schnellwechseladapter einer Baumaschine verbindbar ist, bestehend aus zwei Aufnahmeblechen.The invention relates to an attachment tool for construction equipment with a receptacle via which the attachment tool is connectable to a quick-change adapter of a construction machine, consisting of two receiving plates.
Bei Baumaschinen, beispielsweise Hydraulikbaggern ist es üblich, Anbauwerkzeuge über sogenannte Schnellwechseladapter in einfacher Weise aufzunehmen und wieder abzulegen. Bei Baumaschinen können unterschiedlichste Anbauwerkzeuge verwendet werden. Dabei sind je nach Funktion die Aufnahmen unterschiedlicher Anbauwerkzeuge auf bestimmte Baumaschinen ausgerichtet, das bedeutet, dass bestimmte Baumaschinen, nur mit bestimmten Anbauwerkzeugen mit entsprechend eingestellten Aufnahmen bestimmte Funktionen durchführen können. Als Beispiel eines derartig speziellen Anbauwerkzeugs, das schon von seiner Aufnahmegeometrie an eine bestimmte Baumaschine angepaßt werden muss, wäre ein Gabelträger zu nennen, der beispielsweise an Radladern oder Hydraulikbaggern anbaubar ist. Die Winkel und Positionen beim Einbau der Gabelträger an Baumaschinen beeinflussen die Kinematik und die Traglasten, mit dem das jeweilige Gerät, also beispielsweise der Hydraulikbagger oder der jeweilige Gabelträger bewegt werden kann.In construction machines, such as hydraulic excavators, it is common to easily add and remove tools via so-called quick-change adapter. For construction machinery, a wide variety of attachment tools can be used. Depending on the function, the shots of different attachment tools are geared to specific construction machines, which means that certain construction machines can perform certain functions only with certain attachment tools with correspondingly set shots. As an example of such a special attachment tool, which already has to be adapted from its receiving geometry to a specific construction machine, a fork carriage should be mentioned, which can be attached, for example, to wheel loaders or hydraulic excavators. The angles and positions when installing the fork carriage on construction machines affect the kinematics and the load bearing capacity, with which the respective device, ie For example, the hydraulic excavator or the respective fork carriage can be moved.

In der Praxis hat sich nun gezeigt, dass der Kunde mit der ausgelieferten Gabelträgerkinematik nicht immer zufrieden ist, da sich oft erst bei der Anwendung zeigt, ob ein Gerät sich optimal, eingeschränkt oder unbefriedigend bewegen lässt.In practice, it has now been shown that the customer is not always satisfied with the delivered kinematic kinematics, since often it only becomes apparent during the application whether a device can be moved optimally, restrictedly or unsatisfactorily.
Aus der
Aufgabe der vorliegenden Erfindung ist es nun, ein gattungsgemäßes Anbauwerkzeug derart zu verbessern, dass das Anbauwerkzeug optimal an den Einsatz in der Baumaschine angepaßt werden kann.Object of the present invention is therefore to improve a generic attachment tool such that the attachment tool can be optimally adapted to use in the construction machine.
Erfindungsgemäß wird diese Aufgabe durch ein Anbauwerkzeug mit der Kombination der Merkmale des Anspruchs 1 gelöst. Demnach weist ein Anbauwerkzeug von Baumaschinen eine Aufnahme auf, über die das Anbauwerkzeug mit einem Schnellwechseladapter einer Baumaschine verbindbar ist. Diese Aufnahme besteht aus zwei Aufnahmeblechen, wobei ein Aufnahmekasten in einer vorbestimmten Winkelstellung relativ zum Anbauwerkzeug mit den Aufnahmeblechen verbindbar ist und wobei der Schnellwechseladapter an dem Aufnahmekasten ankuppelbar ist.According to the invention this object is achieved by an attachment tool with the combination of the features of claim 1. Accordingly, an attachment tool of construction machines has a receptacle via which the attachment tool can be connected to a quick-change adapter of a construction machine. This receptacle consists of two receiving plates, wherein a receiving box in a predetermined angular position relative to the attachment tool with the receiving plates is connectable and wherein the quick-change adapter can be coupled to the receiving box.
Erfindungsgemäß sind die Lochbilder der Befestigungsbohrungen so in den Aufnahmeblechen vorgesehen sein, dass der Aufnahmekasten in drei unterschiedlichen Hauptwinkelstellungen mit den Aufnahmeblechen verbindbar ist.According to the invention, the hole patterns of the fastening bores can be provided in the mounting plates in such a way that the mounting box can be connected to the mounting plates in three different main angular positions.
Weiterhin ist erfindungsgemäß das Anbauwerkzeug ein Gabelträger. Hier ist eine erste Winkellage des Gabelträgers einstellbar, in welcher eine größere Stapelhöhe auf dem Gabelträger aufnehmbar ist. In einer zweiten Winkellage kann dagegen eine vergleichsweise höhere Traglast aufgenommen werden. Schließlich kann in einer mittleren zwischen diesen liegenden Winkellage eine mittlere Stapelhöhe bzw. Traglast aufgenommen werden.Furthermore, according to the invention, the attachment tool is a fork carriage. Here, a first angular position of the fork carriage is adjustable, in which a larger stack height can be accommodated on the fork carriage. In contrast, in a second angular position, a comparatively higher load capacity can be absorbed. Finally, a mean stack height or load can be recorded in a middle angular position lying between them.
Die Erfindung besteht also darin, dass nunmehr ein modulartiges System unter Schaffung eines Aufnahmekastens bereitgestellt wird, über das ein spezielles Anbauwerkzeug in unterschiedliche Winkelstellungen bringbar ist, so dass der jeweils gewünschte optimale Einsatz des Anbauwerkzeug zu einer bestimmten Baumaschine gezielt einstellbar ist.The invention thus consists in that now a modular system is provided to create a receiving box, via which a special attachment tool in different angular positions can be brought, so that the particular desired optimal use of the attachment to a specific construction machine is specifically adjustable.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Demnach können vorteilhaft die Aufnahmebleche eine Mehrzahl von Befestigungsbohrungen aufweisen, die so angeordnet sind, dass der Aufnahmekasten in der vorbestimmten Winkelstellung relativ zum Anbauwerkzeug mit den Aufnahmeblechen verbindbar ist.Accordingly, the receiving plates can advantageously have a plurality of mounting holes which are arranged so that the receiving box in the predetermined angular position relative to the attachment tool with the receiving plates is connectable.
Alternativ dazu kann der Aufnahmekasten aber auch einseitig drehfest mit den Aufnahmeflächen verbunden sein, während er auf der anderen Seite gegenüber den Aufnahmeblechen verstellbar ist, um die vorbestimmte Winkelstellung relativ zum Anbauwerkzeug einzustellen. Diese Winkeleinstellung kann beispielsweise über eine Gewindespindel erfolgen. Jeder andere Verstellmechanismus ist hier aber auch geeignet.Alternatively, the receiving box but also on one side rotatably connected to the receiving surfaces, while on the other side relative to the receiving plates is adjustable to adjust the predetermined angular position relative to the attachment tool. This angle adjustment can be done for example via a threaded spindle. Any other adjustment mechanism is also suitable here.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Aufnahmebleche an das Anbauwerkzeug angeschweißt.According to a further advantageous embodiment of the invention, the recording plates are welded to the attachment tool.
Besonders vorteilhaft kann es sein, wenn die Aufnahmebleche an das Anbauwerkzeug nur angeschraubt sind, da hierdurch für verschiedene Aufnahmebedingungen unterschiedliche Aufnahmebleche im Austausch an das Anbauwerkzeug angeschraubt werden könnten.It may be particularly advantageous if the mounting plates are only screwed to the attachment tool, as this different mounting plates could be screwed in exchange for the attachment tool for different recording conditions.
Vorteilhaft ist der Aufnahmekasten durch Verbolzungen oder Schwerspannstifte mit den Aufnahmeblechen verbindbar.Advantageously, the receiving box by Verbolzungen or heavy-duty pins with the receiving plates connectable.
Gemäß einer weiteren Ausgestaltung der Erfindung können die Lochbilder in den Aufnahmeblechen so gewählt sein, dass der Aufnahmekasten Zwischenstellungen zwischen den Hauptwinkelstellungen einnehmen kann.According to a further embodiment of the invention, the hole patterns in the receiving plates can be selected so that the receiving box can take intermediate positions between the main angular positions.
