Description
Absetzer mit Eimerleiter zum Herstellen eines Aufnahmegrabens von trapezförmigem Querschnitt Es sind Baggereinrichtungen zum Herstellen von Gräben bekannt, bei welchen die ausgrabende Eimerleiter parallel zur Marschrichtung des Baggers liegt, so daß mit ihnen nur Gräben mit rechteckigem Querschnitt hergestellt werden können. Bei solchen Gräben besteht immer die Gefahr des Nachstürzens der Seitenwände, was in weit größerem Maße dann auftritt, wenn das Bodenmaterial eine geringe innere Festigkeit besitzt und außerdem in der Nähe der Grabenböschung ein Zugverkehr herrscht. Auch müssen zum Ausbaggern rechteckiger Gräben die Eimer freischneidend ausgebildet werden, um. ein Senken der Leiter zum. Einschneiden tieferer Gräben zu ermöglichen. Hierdurch werden solche Eimer in der Herstellung teurer, da die Form derselben infolge der seitlichen Ausbuchtung einen größeren Arbeitsaufwand erfordert.Spreader with bucket ladder to create a receiving trench for trapezoidal cross-section There are excavation devices for creating trenches known, in which the excavating bucket ladder parallel to the direction of the Excavator lies so that only trenches with a rectangular cross-section are made with them can be. With such trenches there is always the risk of the falling Sidewalls, which occurs to a far greater extent when the floor material is a has low internal strength and also a near the ditch embankment There is train traffic. The buckets also have to cut freely when digging rectangular trenches be trained to. lowering the ladder to. Cutting deeper trenches to enable. This makes such buckets more expensive to manufacture because the Form the same due to the lateral bulge a greater amount of work requires.
Es sind auch schon an den unteren Umkehrrollen der Baggerleitern besondere Vorrichtungen angebracht, die dem Aufnahmegraben einen trapezförmigen Querschnitt geben. Die Erfindung bietet den Vorteil, daß besondere Vorrichtungen nicht mehr erforderlich sind zum Herstellen derartiger Gräben. Die Erfindung bezieht sich auf einen fahrbaren Absetzer mit portalartiger Durchfahrt, in dessen Mitte eine heb- und senkbare Eimerleiter angeordnet ist, die dem Aufnahmegraben einen trapezförmigen Querschnitt gibt. Die Erfindung besteht darin, daß die Eimerleiter schräg zur Fahrrichtung angeordnet ist.There are also special features on the lower reversing rollers of the excavator ladders Devices attached to the receiving trench a trapezoidal cross-section give. The invention offers the advantage that special devices no longer are required to produce such trenches. The invention relates to a mobile spreader with a portal-like passage, in the middle of which a lifting and lowerable bucket ladder is arranged, which the receiving trench a trapezoidal Cross section there. The invention consists in the fact that the bucket ladder is inclined to the direction of travel is arranged.
Auf der Zeichnung ist die Erfindung schematisch dargestellt, und zwar in Abb. = in Seitenansicht und in Abb. 2 im Grundriß.In the drawing, the invention is shown schematically, namely in Fig. = in side view and in Fig. 2 in plan.
Das Fahrzeug, beispielsweise Bagger oder Absetzapparat a, ist mit einer fest eingebauten, schräg zur Marschrichtung des Gerätes liegenden Eimerleiter b versehen, welche die Eimerkette c trägt. Letztere wird zum Ausheben des Grabens d benutzt, wobei die Außenkanten der schneidenden Eimer einerseits am Umkehrturas e und andererseits am Knickturas f die Grabenböschungen g und la herstellen, wogegen die Unterkanten der Eimer i die Sohle k des Grabens d ausschneiden.The vehicle, for example excavator or settling apparatus a, is with a permanently installed bucket ladder at an angle to the direction of travel of the device b provided, which carries the bucket chain c. The latter is used to dig the trench d used, with the outer edges of the cutting bucket on the one hand at the reverse turas e and, on the other hand, at the buckle f, create the ditch slopes g and la, on the other hand the lower edges of the buckets i cut out the bottom k of the trench d.
Bei Absetzapparaten, bei welchen das Abraumgut mittels Wagen l zugebracht und in den Graben geschüttet wird, dient die Baggereimerkette c gleichzeitig zur Weiterleitung des Materials an die Transporteinrichtungen des Gerätes.In the case of depositing devices in which the debris is brought by means of trolley l and is poured into the trench, the bucket chain c also serves to Forwarding of the material to the transport facilities of the device.
Die Eimerleiter b ist als Knickleiter ausgebildet, wobei zwischen Umkehrturas e und Knickturas f ein weiterer Knicktüras 7n vorgesehen ist, um unter Beibehaltung der Böschungen dem Graben d eine bestimmte Tiefe geben zu können. .The bucket ladder b is designed as an articulated ladder, with a further articulated door 7n being provided between the reverse turas e and the kinked turas f in order to be able to give the trench d a certain depth while maintaining the embankments. .
