Description

Eimerkettenbagger mit einer mittels Gleiskettenfahrwerke unterstützten Eimerleiter Die Erfindung betrifft einen Eimerkettenbagger mit einer am Baggergestell in lotrechter Ebene schwenkbar gelagerten Eimerleiter, die von selbständig verfahrbaren Gleiskettenfahi-werken unterstützt ist, die mit der Eimerleiter heb- und senkbar und waagerecht schwenkbar verbunden sind.Bucket chain excavator with one supported by crawler tracks Bucket ladder The invention relates to a bucket chain excavator with one on the excavator frame Bucket ladder pivoted in a vertical plane, which can be moved independently Gleiskettenfahi-werken is supported, which can be raised and lowered with the bucket ladder and are connected to pivot horizontally.

Bei den bekannten Eimerkettenbaggern dieser Art befinden sich die die Eimerleiter unterstützenden Gleiskettenfahrwerke vor und hinter der Eimlerleiter, so daß, wenn das in der Fahrtrichtung vorn liebende Gleiskettenfahrwerk eine Unebenheit in der Böschung überfährt, die Eimerleiter gegenüber dem Baggerfahrwerk um ihre Längsachse verdreht wird.In the known bucket chain excavators of this type are the caterpillar tracks supporting the bucket ladder in front of and behind the bucket ladder, so that if the crawler track loving in the direction of travel has a bump runs over in the embankment, the bucket ladder opposite the excavator undercarriage around hers Longitudinal axis is twisted.

Um diese Bewegung der Eimerleiter ohne Zwängungen zu ermöglichen, ist nach der Erfindung die Eimerleiter mit dem Baggergestell mittels eines in Längsrichtung, der Eimerleiter verlaufenden Zapfens drehbar verbunden. Hierbei kann auch das die Eimerleiter unterstützende Gleiskettenfahrwerk mit der Eimerleiter mittels eines in Längsrichtung der Eimerleiter verlaufenden Zapfens drehbar verbunden sein.To enable this movement of the bucket ladder without constraints, is according to the invention, the bucket ladder with the excavator frame by means of a in the longitudinal direction, the bucket ladder extending pin rotatably connected. Here the Bucket ladder supporting caterpillar with the bucket ladder by means of a be rotatably connected in the longitudinal direction of the bucket ladder extending pin.

Hierdurch wird erreicht, daß zusätzliche Beanspruchungen der Eimerleiter beim überfahren von Unebenheiten, die insb'es'ondere am Strossenende auftreten, vermieden werden.This ensures that additional stresses on the bucket ladder when driving over bumps that occur in particular at the end of the bench, be avoided.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt.The invention is shown in the drawing in an exemplary embodiment.

Abb. i zeigt :einen Eimerkettenbagger in Seitenansicht, Abb. 2 eine Draufsicht dazu und Abb.3 das Fahrwerk der Eimerleiter in Stirnansicht.Fig. I shows: a bucket chain excavator in side view, Fig. 2 shows a Top view and Fig. 3 the chassis of the bucket ladder in a front view.

Die von den Gleiskettenfahrwerken g und lt unterstützte Eimerleiter f ist mit ihrem oberen Ende um einen in Längsrichtung der Eimerleiter verlaufenden Längszapfen n drehbar, der mit seinem oberen Ende in der waagerechten Schwenkachse o der beiden Hebel c gelagert ist. Diese Verbindung der Eimerleiter f mit dein Baggerhaus b gestattet eine Verdrehung der Eimerleiter f um ihre Längsachse, ohne daß hierbei Zwängungen auftreten.The bucket ladder supported by the caterpillar tracks g and lt f is with its upper end around a longitudinal direction of the bucket ladder Longitudinal pin n rotatable with its upper end in the horizontal pivot axis o the two levers c is mounted. This connection of the bucket ladder f with your excavator house b allows the bucket ladder f to be rotated about its longitudinal axis without this Constraints occur.

Die beiden Gleiskettenfahrwerke g und lt sind mittels eines Ausgleichshebels p miteinander verbunden, der auf den Gleiskettenfahrwerken kugelgelenkig aufgelagert und mit der Eimerleiter f um den Längszapfen n' schwingbar ist. Zum Lenken der Gleiskettenfahrwerke dienen die Lenkhebel g1 und hl-.The two crawler tracks g and lt are by means of a compensating lever p connected to one another, which is supported by ball-and-socket joints on the crawler tracks and is swingable with the bucket ladder f about the longitudinal pin n '. For steering the caterpillar tracks serve the steering levers g1 and hl-.

Mit der beschriebenen Lagerung können zusätzliche Beanspruchungen der Eimerleiter f beim Befahren unregelmäßiger Böschungswände nicht mehr auftreten-, da die Eimerleiter f unabhängig von dem sie unterstützenden Gleiskettenfahrwerk und vom Baggergestell b gelagert ist.The storage described can result in additional stresses the bucket ladder f no longer occurs when driving on irregular slope walls, since the bucket ladder f is independent of the caterpillar track that supports it and is supported by the excavator frame b.
