The working cylinder (44) is accommodated inside a frame (24) which is closed in a box shape and is firmly connected to the bucket body (10). <IMAGE>

Description

Die Erfindung betrifft einen Grabenräumlöffel, der über eine in der Quermittelebene des Löffels verlaufende Schwenkachse mit einem Schwenkkopf verbunden ist und der zum Drehen um seine Schwenkachse wenigstens einen Arbeitszylinder trägt, der innerhalb eines kastenförmigen Rahmens untergebracht ist, welcher fest mit dem Löffelkörper verbunden ist.The invention relates to a trench clearing bucket which is connected to a swivel head via a swivel axis running in the transverse central plane of the bucket and which carries at least one working cylinder for rotation about its swivel axis and is housed within a box-shaped frame which is firmly connected to the bucket body.

Bei bekannten Grabenräumlöffeln dieser Bauart sind die hydraulischen Arbeitszylinder an der Oberseite des Löffelkörpers offen und ungeschützt gelagert, wobei die Druckleitungen ebenfalls offen und neben dem Schwenkkopf nach oben zu einem Stiel führen, an welchem der Schwenkkopf aufgehängt ist. Um die Hydraulikanlage wenigstens teilweise zu schützen, trägt ein an der Oberseite des Löffelkörpers angebrachtes Torsionsrohr ein Schutzschild, hinter welchem die Arbeitszylinder und Druckleitungen nach oben und hinten jedoch ungeschützt montiert sind.In known trench clearing buckets of this type, the hydraulic working cylinders are mounted open and unprotected on the top of the bucket body, the pressure lines also being open and leading upwards next to the swivel head to a stick on which the swivel head is suspended. In order to protect the hydraulic system at least partially, a torsion tube attached to the top of the bucket body carries a protective shield, behind which the working cylinders and pressure lines are mounted unprotected upwards and backwards.

Ein Grabenräumlöffel der eingangs genannten Bauart ist aus der EP-A 142 479 bekannt. Bei diesem bekannten Grabenräumlöffel greift der Schwenkkopf mit einem an einer Seite nach unten abstehenden Flansch durch einen Schlitz in den Löffelkörper ein; um hier den Schwenkmechanismus, der zwei Arbeitszylinder hat, gegen vom Löffelkörper aufgenommenes Material - Erdreich, Kies und dgl. - zu schützen, ist durch zwei verhältnismäßig schwache, winklig zueinander angeordnete Wände ein abgeschlossener Raum gebildet. Über die Führung und den Anschluß von Druckleitungen ist nichts weiter ausgesagt.A trench clearing bucket of the type mentioned at the outset is known from EP-A 142 479. In this known trench clearing bucket, the swivel head engages with a flange projecting downward on one side through a slot in the bucket body; In order to protect the swivel mechanism, which has two working cylinders, against material picked up by the bucket body - soil, gravel and the like - a closed space is formed by two relatively weak, angularly arranged walls. Nothing else is said about the routing and connection of pressure lines.

Ein wesentlicher Nachteil der bekannten Konstruktion ist darin zu sehen, daß der kastenförmig geschlossene Raum innerhalb des Grabenräumlöffels ausgebildet ist, wo aufgrund des rauhen Betriebs auf einer Baustelle Beschädigungen oder Verformungen der verhältnismäßig dünnen Wand nicht zu vermeiden sind. Außerdem ist aufgrund dieser Lage im Löffelkörper der kastenförmige Raum nur mit Schwierigkeiten zugänglich, wenn etwa ein defekter Arbeitszylinder oder Dichtungen für die Druckleitungen ausgewechselt werden müssen. Hinzu kommt, daß der Löffelkörper eine von üblichen Konstruktionen abweichende Sonderbauform hat, so daß der geschützte Einbau der Arbeitszylinder mit den diese versorgenden Druckleitungen bei herkömmlichen Löffelkonstruktionen nachträglich nicht mehr möglich ist.A major disadvantage of the known construction can be seen in the fact that the box-shaped closed space is formed within the ditch cleaning spoon, where damage or deformation of the relatively thin wall cannot be avoided due to the rough operation on a construction site. In addition, due to this position in the bucket body, the box-shaped space is difficult to access if, for example, a defective working cylinder or seals for the pressure lines have to be replaced. In addition, the bucket body has a special design that deviates from conventional designs, so that the protected installation of the working cylinders with the pressure lines supplying them is no longer possible with conventional bucket designs.

Die US-A 4 958 981 hat eine Greifzange zum Gegenstand, deren schwenkbare Zinken mit einem Arbeitszylinder verbunden sind, welcher ungeschützt innerhalb der Greifzange untergebracht ist. Die Druckleitungen für den Arbeitszylinder verlaufen am Löffelstiel entlang nach unten, und zwar unmittelbar zwischen den beiden Seitenwangen des Schwenkkopfes, was die Gefahr in sich birgt, daß sie bei einem Schwenken des Schwenkkopfes zwischen dem Ende des Löffelstiels und den Seitenwangen eingeklemmt werden können.The US-A 4 958 981 has the object of a gripper, the pivotable tines are connected to a working cylinder which is housed unprotected within the gripper. The pressure lines for the working cylinder run down along the arm, directly between the two side cheeks of the swivel head, which entails the risk that they can be caught between the end of the arm and the side cheeks when the swivel head is swiveled.

Der Erfindung liegt die Aufgabe zugrunde, einen Grabenräumlöffel zur Verfügung zu stellen, bei dem der hydraulische Schwenkmechanismus einschließlich der zu diesem führenden Druckleitungen allseitig gegen Beschädigungen oder Zerstörungen geschützt ist, wobei die hierfür erforderlichen Maßnahmen an leicht zugänglichen Stellen auch bei herkömmlichen Löffelkörpern ohne konstruktiv komplizierte Umbaumaßnahmen vorgesehen werden können.The invention has for its object to provide a trench clearing bucket in which the hydraulic swivel mechanism including the pressure lines leading to it is protected on all sides against damage or destruction, the measures required for this in easily accessible locations even with conventional bucket bodies without structurally complicated conversion measures can be provided.

Bei einem Grabenräumlöffel der im Oberbegriff des patentanspruchs 1 angegebenen Bauart wird diese Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.With a trench clearing bucket of the type specified in the preamble of patent claim 1, this task solved according to the invention by the characterizing features of claim 1.

Mit der Erfindung wird der erhebliche Vorteil erzielt, daß selbst im rauhesten Betrieb die Gefahr beseitigt ist, daß die Druckleitungen abgequetscht oder durch Gestrüpp abgerissen werden, da sie im Bereich des Grabenräumlöffels an jeder Stelle geschützt verlaufen. Selbst überrollendes Erdreich oder Geröll führt zu keinen Beschädigungen und Ausfällen, da der kastenförmig geschlossene Rahmen einen wirksamen Schutz für das Hydrauliksystem (Arbeitszylinder und Druckleitungen) darstellt. Der kastenförmig geschlossene Rahmen hat zudem den weiteren Vorteil, daß er ein Versteifungselement für den Löffelkörper bildet. Dieser Rahmen nimmt alle Kräfte auf, die vom Schwenkkopf auf den Löffelkörper mit seinen Seitenschneiden übertragen werden. Ein weiterer Vorteil besteht darin, daß der Arbeitszylinder an der Oberseite des Löffelkörpers etwa mittig und nicht seitlich mit dem Schwenkkopf verbunden ist, was sich auf eine gleichmäßige Kraftverteilung vorteilhaft auswirkt.With the invention, the considerable advantage is achieved that even in the harshest of operation the risk is eliminated that the pressure lines are squeezed off or torn off by brushwood, since they run protected at all points in the area of the ditch cleaning bucket. Even rolling over soil or rubble does not lead to damage and failures, since the box-shaped closed frame provides effective protection for the hydraulic system (working cylinder and pressure lines). The box-shaped closed frame also has the further advantage that it forms a stiffening element for the spoon body. This frame absorbs all forces that are transferred from the swivel head to the bucket body with its side cutting edges. Another advantage is that the working cylinder on the top of the bucket body is connected approximately centrally and not laterally to the swivel head, which has an advantageous effect on an even distribution of force.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß an dem Rahmen Schmiernippel einer Zentralschmieranlage angebracht sind, über welche alle Lagerstellen des Grabenräumlöffels geschmiert werden können. Von den Schmiernippeln führen innerhalb des kastenförmig geschlossenen Rahmens die Schmierleitungen geschützt zu den Lagerstellen.According to a further feature of the invention it is provided that lubrication nipples of a central lubrication system are attached to the frame, via which all bearing points of the trench clearing spoon can be lubricated. The lubrication lines run from the grease nipples to the bearing points within the box-shaped closed frame.

Die Erfindung ist nachstehend an einem Ausführungsbeispiel erläutert, das in der Zeichnung dargestellt ist.The invention is explained below using an exemplary embodiment which is illustrated in the drawing.

Figur 1 zeigt eine schräge Vorderansicht des Grabenräumlöffels, dessen Löffelkörper 10 innen so geformt ist, daß scharfe Ecken und Kanten weitgehend vermieden sind, wodurch sich eine optimale Grabkurve ergibt, die hohe Füllmengen aufnehmen kann. Im mittleren Bereich des Löffelkörpers 10 sind zwei Versteifungsrippen 12 angebracht. Das vordere Schneidmesser 14 ist über die Seitenwangen 15 des Löffelkörpers 10 hinaus verlängert, so daß sich an beiden Seiten je ein überstehendes Schneidmesser 18 ergibt. An der Rückseite des Löffelkörpers 10 ist eine Böschungsschneide 20 angebracht, die über Rippen 22 mit dem Löffelkörper 10 verbunden ist.FIG. 1 shows an oblique front view of the trench clearing bucket, the bucket body 10 of which is shaped on the inside in such a way that sharp corners and edges are largely avoided, which results in an optimal digging curve which can take up large quantities. In the central area of the spoon body 10, two stiffening ribs 12 are attached. The front cutting knife 14 is extended beyond the side cheeks 15 of the spoon body 10, so that there is a protruding cutting knife 18 on both sides. On the back of the spoon body 10, an embankment cutting edge 20 is attached, which is connected to the spoon body 10 by means of ribs 22.

An der Oberseite des Löffelkörpers ist ein starker, kastenförmig geschlossener Rahmen 24 angebracht, dessen Seitenwände einstückig mit den Seitenwangen 16 des Löffelkörpers 10 ausgebildet sind. In seinem mittleren Bereich trägt dieser Rahmen 24 vorn und hinten je ein dreieckiges Lagerschild 26 für eine Schwenkachse 28. Über diese Schwenkachse 28 ist der Löffelkörper 10 mit einem Schwenkkopf 30 verbunden, der an einem nicht gezeigten Stiel eines Baggerfahrzeuges o.dgl. angebracht werden kann. Über diesen Stiel wird der Grabenräumlöffel in seiner Quermittelebene bewegt.A strong, box-shaped closed frame 24 is attached to the top of the spoon body, the side walls of which are formed in one piece with the side cheeks 16 of the spoon body 10. In its central region, this frame 24 carries a triangular end shield 26 for a pivot axis 28 at the front and rear. Via this pivot axis 28, the bucket body 10 is connected to a pivot head 30, or the like, on a stick of an excavator vehicle, not shown. can be attached. The trench clearing bucket is moved in its transverse median plane via this handle.

Der Schwenkkopf 30 hat eine Grundplatte 32, von der gemäß Figur 1 zwei parallele Seitenwangen 34 nach oben abstehen. An der Unterseite der Grundplatte 32 sind zwei parallel zueinander verlaufende Lageraugen 36 befestigt, die zur Aufnahme der Schwenkachse 28 dienen. Das untere Ende der Lageraugen 36 trägt jeweils einen Ansatz 38 mit einer Lagerbohrung 40. An dieser Lagerbohrung 40 greift das Ende einer Kolbenstange 42 eines hydraulischen Arbeitszylinders 44 an, dessen gegenüberliegendes Ende über ein Pendellager 46 innerhalb des kastenförmigen Rahmens 24 an der Oberseite des Löffelkörpers 10 aufgehängt ist.The swivel head 30 has a base plate 32, from which two parallel side cheeks 34 protrude upwards according to FIG. On the underside of the base plate 32, two bearing eyes 36, which run parallel to one another, are fastened and serve to receive the pivot axis 28. The lower end of the bearing eyes 36 each carries a shoulder 38 with a bearing bore 40. The end of a piston rod 42 of a hydraulic working cylinder 44, the opposite end of which engages with this bearing bore 40 End is suspended via a self-aligning bearing 46 within the box-shaped frame 24 on the top of the spoon body 10.

Zum Schwenken des Löffelkörpers 10 um die in seiner Quermittelebene liegende Schwenkachse 28 werden im allgemeinen zwei Arbeitszylinder 44 eingesetzt, von denen in Figur 2 der zweite Arbeitszylinder auf der rechten Seite durch den kastenförmigen Rahmen 24 verdeckt ist.To pivot the bucket body 10 about the pivot axis 28 lying in its transverse center plane, two working cylinders 44 are generally used, of which in FIG. 2 the second working cylinder on the right side is covered by the box-shaped frame 24.

Die Arbeitszylinder 44 werden von einer zentralen Hydraulikanlage des Baggerfahrzeugs o. dgl. betätigt. Von dort laufen die entsprechenden Druckleitungen 48 am oben erwähnten Stiel entlang zum Schwenkkopf 30, wo sie durch Bohrungen 50 in den Seitenwangen 34 nach innen zu der Grundplatte 32 geführt sind. Durch eine Aussparung 52 innerhalb der Grundplatte 32 führen die Druckleitungen 48 kann in das Innere des kastenförmig geschlossen Rahmens 24, wo sie auf diese Weise geschützt an die Arbeitszylinder 44 angeschlossen sind.The working cylinders 44 are actuated by a central hydraulic system of the excavator vehicle or the like. From there, the corresponding pressure lines 48 run along the above-mentioned handle to the swivel head 30, where they are guided inwards through holes 50 in the side cheeks 34 to the base plate 32. Through a recess 52 within the base plate 32, the pressure lines 48 can lead into the interior of the box-shaped closed frame 24, where they are connected to the working cylinders 44 in a protected manner.

In Figur 2 ist angedeutet, daß an der Rückseite des kastenförmigen Rahmens 24 bzw. an dem hinteren Lagerschild 26 eine Reihe von Schmiernippeln 54 angebracht ist, von der Schmierleitungen 56 zu den Lagerstellen des Grabenräumlöffels führen, die im Bereich der Lager der Arbeitszylinder 44 und der Schwenkachse 28 liegen. Auf diese Weise steht eine Zentralschmieranlage zur Verfügung, die die Wartung wesentlich vereinfacht.In Figure 2 it is indicated that on the back of the box-shaped frame 24 or on the rear bearing plate 26 a series of grease nipples 54 is attached, from the lubrication lines 56 lead to the bearing points of the ditch cleaning bucket, which in the area of the bearings of the working cylinders 44 and Swivel axis 28 lie. In this way, a central lubrication system is available, which considerably simplifies maintenance.
