Description

Die Erfindung betrifft ein Grabgefäß, insbesondere einen Grabenräumlöffel, für Bagger und ähnliche Baumaschinen, mit einer, auf seiner Oberseite mittig angeordneten Befestigungsvorrichtung, die eine Halterung zum Anschluß an den Ausleger einer Baumaschine und eine, zwischen Halterung und der Oberseite des Grabgefäßes angeordnete Kippvorrichtung enthält, welche im wesentlichen aus einem, mit seiner Drehachse in Längsrichtung des Auslegers angeordneten Drehlager und zwei, zwischen der Oberseite des Grabgefäßes und der Kippvorrichtung jeweils gelenkig angeschlossene und, in Längsrichtung des Auslegers gesehen, seitlich von der Befestigungsvorrichtung angeordneten Hydraulikzylinder besteht.The invention relates to a digging vessel, in particular a trench clearing bucket, for excavators and similar construction machines, with a fastening device arranged centrally on its upper side, which contains a holder for connection to the boom of a construction machine and a tilting device arranged between the holder and the upper side of the digging vessel. which essentially consists of a rotation arranged with its axis of rotation in the longitudinal direction of the boom camp and two, between the top of the grave and the tilting device each articulated and, seen in the longitudinal direction of the boom, arranged laterally from the fastening device hydraulic cylinders.

Bei solchen bekannten Grabqefäßen ist das Drehlager der Kippvorrichtung unmittelbar benachbart zur Oberseite des Grabgefäßes und oberhalb dieser angeordnet und die seitlichen Hydraulikzylinder, welche die Kippbewegung des-Grabgefäßes um die Drehachse bewirken, sind mit ihren befestigungsvorrichtungsseitiqen Enden oberhalb des Drehlagers an der Halterung gelenkig angeschlossen. Die grabgefäßseitigen Enden der Hydraulikzylinder sind in Abhängigkeit der Bauhöhe der Kippvorrichtung und Halterung und in Abhängigkeit der Baulänge der verwendeten Hydraulikzylinder entweder nahe dem Drehlager oder benachbart zu den, das Grabgefäß in seiner seitlichen Ausdehnung begrenzenden Seitenwänden auf der Oberseite des Grabgefäßes ebenfalls gelenkig befestigt.In such known grave vessels, the pivot bearing of the tilting device is arranged directly adjacent to the top of the grave vessel and above it, and the lateral hydraulic cylinders, which bring about the tilting movement of the grave vessel about the axis of rotation, are articulatedly connected to the holder with their fastening device-side ends above the rotary bearing. The grave vessel-sided ends of the hydraulic cylinders are a function of the height of the tilting device and holder and depending on the overall length of the hydraulic cylinders used either close to the pivot bearing or adjacent to, the grave vascular g in its lateral extension defining side walls on top of the grave efäßes also articulated.

Nachteilig bei diesen bekannten Ausführungen ist, daß die Hydraulikzylinder, insbesondere die gegen äußere, mechanische Einwirkungen empfindlichen Kolbenstangen ungeschützt gegen Beschädigungen durch Erd- und Felsbrocken während des Arbeitseinsatzes sind, da die so angeordneten Hydraulikzylinder unmittelbar in den Arbeitsbereich der Grabschaufel gelangen.A disadvantage of these known designs is that the hydraulic cylinders, in particular the piston rods, which are sensitive to external mechanical influences, are unprotected against damage caused by boulders and rocks during work, since the hydraulic cylinders arranged in this way reach the working area of the digging shovel directly.

Häufiges Auswechseln der beschädigten Hydraulikzylinder hat längere Ausfallzeiten der Baumaschine zur Folge und ist deshalb äußerst kostennachteilig.Frequent replacement of the damaged hydraulic cylinders results in longer downtimes for the construction machine and is therefore extremely cost-disadvantageous.

Aufgabe der Erfindung ist es, bei einem Grabgefäß, insbesondere einem Grabenräumlöffel, für Bagger und ähnliche Baumaschinen die Befestigungsvorrichtung mit Halterung und Kippvorrichtunq und den die Kippbewegung bewirkenden Hydraulikzylindern so auszubilden, daß die gegen insbesondere mechanische Umwelteinflüsse besonders empfindlichen Hydraulikzylinder mit ihren Kolbenstangen und den zujehörigen Hydraulikschläuchen nahezu vollständig qeschützt bzw. in das Grabqefäß integriert sind, und insbesondere die vorstehend aufgeführten Nachteile vermieden werden.The object of the invention is to design the fastening device with holder and tilting device and the hydraulic cylinders causing the tilting movement in a digging vessel, in particular a digging bucket, for excavators and similar construction machines so that the hydraulic cylinders with their piston rods and the associated hydraulic hoses, which are particularly sensitive to mechanical environmental influences in particular are almost completely protected or integrated into the grave vessel, and in particular the disadvantages listed above are avoided.

Diese Aufgabe wird dadurch gelöst, daß bei einem Grabgefäß der eingangs genannten Art die Hydraulikzylinder mit ihren befestigungsvorrichtungsseitigen Enden unterhalb des Drehlagers zwischen diesem und der Oberseite des Grabgefäßes an der Kippvorrichtung anqeschlossen sind.This object is achieved in that, in a digging vessel of the type mentioned at the outset, the hydraulic cylinders are connected to the tilting device with their ends on the fastening device side below the pivot bearing between the latter and the top of the digging vessel.

Durch diese erfindungsgemäße Ausbildung wird erreicht, daß die Hydraulikzylinder, insbesondere aber ihre Kolbenstangen in unmittelbarer Nähe zu der Oberseite des Grabgefäßes und im unmittelbaren Bereich der Befestigungsvorrichtung anneordnet und verdeckt sind.This configuration according to the invention ensures that the hydraulic cylinders, but in particular their piston rods, are arranged and covered in the immediate vicinity of the upper side of the grave vessel and in the immediate area of the fastening device.

In vorteilhafter Weiterbildung ist die Kippvorrichtung im wesentlichen aus zwei, senkrecht zur Ebene der Ausleqerachse und im Abstand hintereinander angeordnete, als Tellerscheiben ausqebildete kreisförmige und an der Halterung befestigte Flansche gebildet, in deren Kreismittelpunkt die Drehachse des Drehlagers angeordnet ist und welche wiederum in zwei, zu den Tellerscheiben parallel angeordnete, auf der Oberseite des Grabgefäßes befestigte Laschen gelagert ist.In an advantageous further development, the tilting device is essentially formed from two circular flanges, which are arranged perpendicularly to the plane of the Ausleqerachse and at a distance from one another and designed as plate disks and fastened to the holder, in the center of the circle of which the axis of rotation of the rotary bearing is arranged and which in turn are in two the plates are arranged in parallel, attached to the top of the grave flaps mounted.

Durch die tellerförmige Ausbildung der Kippvorrichtung ergibt sich ein größerer Abstand zwischen der Oberseite des Grabgefäßes und dem Drehlager der Kippvorrichtunq, als es bei den bekannten Vorrichtunqen der Fall ist.The plate-shaped design of the tilting device results in a greater distance between the top of the grave vessel and the pivot bearing of the tilting device than is the case with the known devices.

Vorteilhaft sind die beiden Hydraulikzylinder mit ihren grabnefäßseitigen Enden benachbart zu den Seitenwänden des Grabgefäßes auf dessen Oberseite gelenkig angeschlossen und mit ihren kippvorrichtunqsseitigen Enden ebenfalls gelenkig in radialem Abstand von der Drehachse der Kippvorrichtung an einer der Tellerscheiben angeschlossen.The two hydraulic cylinders are advantageously connected in an articulated manner with their ends on the side of the grave vessel adjacent to the side walls of the grave vessel and on their upper side with their ends on the tilting device also articulatedly connected to one of the plate disks at a radial distance from the axis of rotation of the tilting device.

Diese Ausbildung der Kippvorrichtunq ermöglicht insbesondere die Anordnung der Hydraulikzylinder nahezu parallel zu der Oberseite des Grabgefäßes.This design of the tilting device enables, in particular, the arrangement of the hydraulic cylinders almost parallel to the top of the digging vessel.

Vorteilhaft sind die Hydraulikzylinder mit ihren kippvorrichtungsseitigen Enden jeweils an einer der beiden Tellerscheiben befestigt. Hierdurch ergibt sich eine gleichmäßiqerere Verteilung der von den Hydraulikzylindern auf die Kippvorrichtunq bzw. Halterung zu übertragenden Kräfte.The hydraulic cylinders are advantageously attached to one of the two plate disks with their ends on the tilting device side. This results in a more uniform distribution of the forces to be transmitted from the hydraulic cylinders to the tilting device or holder.

In erfindungsgemäßer Weiterbildung ist die Oberseite des Grabqefäßes als Hohlkastenträqer ausgebildet und sind die beiden Hydraulikzylinder innerhalb dieses Hohlträgers angeordnet, wobei der Obergurt des Hohlkastenträgers im Bereich der Tellerscheiben eine entsprechende Ausnehmunq aufweist, durch welche die Tellerscheiben in den Hohlraum des Kastenträqers hineinstehen.In a further development according to the invention, the top of the grave vessel is designed as a hollow box carrier and the two hydraulic cylinders are arranged within this hollow carrier, the upper flange of the hollow box carrier having a corresponding recess in the area of the plate washers, through which the plate discs protrude into the cavity of the box carrier.

Die Ausbildung der Oberseite des Grabgefäßes als Hohlkastenträqer erhöht die Stabilität des Grabqefäßes und dient gleichzeitig durch die erfindangsgemäße Anordnung der Hydraulikzylinder als die Hydraulikzylinder schützende Umhüllung.The design of the top of the grave vessel as a hollow box carrier increases the stability of the grave vessel and at the same time serves as a protective covering for the hydraulic cylinders due to the arrangement of the hydraulic cylinders according to the invention.

Schließlich kann die Ausnehmung in dem Obergurt des Hohlkastenträgers auf zwei, die Tellerscheiben in den Hohlkastenträqer einstehen lassende Schlitze reduziert sein.Finally, the recess in the top chord of the box girder can be reduced to two slits which let the plate washers protrude into the box girder.

Diese Ausbildung der Oberseite des Grabaefäßes als Hohlkastenträqer qewährleisteteinen nahezu vollständinen Schutz der besonders empfindlichen Hydraulikzylinder mit ihren Kolbenstanqen sowie der in diesem Bereich befindlichen Hydraulik-Leitungen. Selbst bei extremem Einsatz des Grabgefäßes können die empfindlichen Teile nicht beschädigt werden, da sie vollständig abgedeckt sind. Hierdurch wird auch eine große Wartungsfreundlichkeit des Arbeitsgerätes erreicht.This design of the top of the grave vessel as a hollow box carrier ensures almost complete protection of the particularly sensitive hydraulic cylinders with their piston rods and the hydraulic lines located in this area. Even with extreme use of the burial vessel, the sensitive parts can not be damaged as they are completely covered. This also ensures that the implement is easy to maintain.

Zur Durchführung von gelegentlichen Wartungsarbeiten sind in der zur Baumaschine hin gelegenen Rückseite des Hohlkastenträgers öffnungen vorgesehen, welche durch entsprechend ausgebildete Deckel abgedeckt werden können.For carrying out occasional maintenance work, openings are provided in the rear of the box girder facing the construction machine, which openings can be covered by appropriately designed lids.

In vorteilhafter Weiterbildung der Erfindung sind die beiden Hydraulikzylinder mit ihren grabgefäßseitigen Enden benachbart zu den Seitenwänden des Grabgefäßes innerhalb des Hohlkastenträgers an dessen Obergurt gelenkig angeschlossen und mit ihren kippvorrichtungsseitigen Enden ebenfalls gelenkig in radialem Abstand von der Drehachse der Kippvorrichtung an den Tellerscheiben angeschlossen.In an advantageous development of the invention, the two hydraulic cylinders are connected in an articulated manner with their ends on the side of the digging vessel adjacent to the side walls of the digging vessel within the hollow box girder to the upper flange thereof and are also articulated with their ends on the side of the tilting device at a radial distance from the axis of rotation of the tilting device on the plate disks.

Diese Befestigung der grabgefäßseitigen Enden der beiden Hydraulikzylinder am Obergurt des Hohlkastenträgers erhöht die Wartungsfreiheit des Grabgefäßes wesentlich, da eventuelle Ablagerungen auf dem Untergurt des Hohlkastenträgers welche durch die Ausnehmungen für die Tellerscheiben im Obergurt in den Hohl kastenträger eingedrungen sein können, die Beweglichkeit der Hydraulikzylinder an ihrem grabgefäßseitigen Befestigungsenden nicht behindern können.This attachment of the ends of the two hydraulic cylinders on the digging vessel side to the top flange of the hollow box girder significantly increases the maintenance freedom of the digging vessel, since any deposits on the bottom flange of the hollow box carrier which may have penetrated through the recesses for the plate washers in the top flange into the hollow box girder, the mobility of the hydraulic cylinders on their Cannot hinder attachment ends on the digging vessel side.

Vorteilhaft sind die Tellerscheiben in ihren beiden, zwischen der Befestigungsstelle der kippvorrichtungsseitigen Enden der Hydraulikzylinder an den Tellerscheiben und der Befestigungsstelle der Tellerscheiben an der Halterung gelegenen Bereichen in ihren Durchmessern reduziert.The diameters of the plate disks are advantageously reduced in their two areas between the attachment point of the ends of the hydraulic cylinder on the tilting device side on the plate disks and the attachment point of the plate disks on the holder.

Hierdurch können die im Obergurt des Hohlkastenträgers für die Tellerscheiben vorzusehenden Ausnehmungen verhältnismäßig klein gehalten werden, wodurch die Möglichkeit des Eindringens von Schmutz etc. in den Hohlkastenträger verringert wird.As a result, the recesses to be provided in the upper flange of the box girder for the plate washers can be kept relatively small, thereby reducing the possibility of dirt, etc. penetrating into the box girder.
