Abstract

A work tool is fitted to the rocker arm (2). On the main arm (1) a further rocker arm (3) is pivotally located, to which a device is fixed, which acts as a forward movement and support aid. The two rocker arms are commonly pivotable, or can be separately pivoted. At least one and preferably both rocker arms are extendable telescopically. A harvester head is fixed to one of the rocker arms (2) while an excavator is fixed to the rocker arm. The two rocker arms can be connected to one another, in which case they are commonly pivotable by means of a single hydraulic cylinder.

Description

Die Erfindung betrifft einen Ausleger für ein Fahrzeug mit einem am Fahrzeugrahmen schwenkbar befestigten Hauptarm und einem am Hauptarm schwenkbar befestigten Wipparm, an dem ein Arbeitswerkzeug befestigt ist.The invention relates to a boom for a vehicle with a main arm pivotally attached to the vehicle frame and a rocker arm pivotally attached to the main arm, to which a work tool is attached.

Arbeitsmaschinen, insbesondere Holzbearbeitungsmaschinen, die in schwer zugänglichem oder steilem Gelände fahren müssen, sind häufig mit einem Fahrwerk ausgestattet, das insbesondere bei geneigtem oder steilem Gelände einen Niveauausgleich ermöglicht bzw. die Überwindung größerer örtlicher Hindernisse ermöglicht. Dennoch ist die Geländetauglichkeit derartiger Arbeitsmaschinen, insbesondere bei weichem oder losem Untergrund, begrenzt.Working machines, in particular woodworking machines, which have to drive in difficult to access or steep terrain, are often equipped with a chassis that enables level compensation, in particular on inclined or steep terrain, or enables larger local obstacles to be overcome. Nevertheless, the suitability for off-road use of such work machines, especially in the case of soft or loose ground, is limited.

Es wurde daher auch schon vorgeschlagen, den Ausleger, an dem z.B. Holzbearbeitungswerkzeuge, sogenannte Harvesterköpfe, angeordnet sind, als Fortbewegungshilfe heranzuziehen, um auch in sehr steilem oder schwierigem Gelände voranzukommen oder Hindernisse zu überwinden. Dabei hat sich jedoch herausgestellt, daß dies nur in sehr eingeschränktem Maße möglich ist, da einerseits die Gefahr besteht, daß der Harvesterkopf beschädigt wird und anderseits für die Befestigung zusätzlicher Fortbewegungshilfsmittel am Ausleger kein Raum ist, ohne die Einsatzmöglichkeiten des Harvesterkopfes zu beschränken.It has therefore already been proposed to use the boom on which e.g. Woodworking tools, so-called harvester heads, are arranged to be used as a locomotion aid in order to advance even in very steep or difficult terrain or to overcome obstacles. However, it has been found that this is only possible to a very limited extent, since on the one hand there is a risk that the harvester head is damaged and on the other hand there is no space for attaching additional locomotion aids to the boom without restricting the possible uses of the harvester head.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Ausleger zur Verfügung zu stellen, der als Fortbewegungshilfe sehr gut einsetzbar ist, ohne daß die Gefahr besteht, daß der Harvesterkopf beschädigt wird oder daß dessen Einsatzmöglichkeiten beschränkt werden.The invention is therefore based on the object of providing a boom which can be used very well as a locomotion aid without the risk that the harvester head is damaged or that its possible uses are restricted.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Ausleger dadurch, daß am Hauptarm ein weiterer Wipparm schwenkbar gelagert ist, an dem eine Vorrichtung befestigt ist, die als Fortbewegungshilfe bzw. als Abstützhilfe dient.This object is achieved in a generic boom in that a further rocker arm is pivotally mounted on the main arm, to which a device is attached which serves as a locomotion aid or as a support aid.

Ein gattungsgemäßes Fahrzeug ist aus der US 4 444 542 A bekannt. Bei diesem Erdbearbeitungsfahrzeug sind am Rahmen eines Drehtisches zwei Ausleger parallel nebeneinander gelagert, wobei jeder Ausleger aus einem Hauptarm und einem an diesem verschwenkbar gelagerten Wipparm besteht. Am Wipparm jedes Auslegers ist ein Arbeitswerkzeug, z.B. eine Baggerschaufel und ein Hydrohammer, befestigt.A generic vehicle is known from US 4,444,542 A. In this earth-working vehicle, two arms are mounted parallel to one another on the frame of a turntable, each arm consisting of a main arm and a rocker arm pivotably mounted on it. There is a working tool on the luffing arm of each boom, e.g. an excavator shovel and a hydraulic hammer attached.

Demgegenüber wird bei der Erfindung vorgeschlagen, nur einen einzigen Hauptarm zu verwenden und an diesem einen weiteren Wipparm schwenkbar zu lagern, was mehrere Vorteile mit sich bringt.In contrast, it is proposed in the invention to use only a single main arm and to pivotably mount another rocker arm thereon, which has several advantages.

Zum einen kann der technische Aufwand beträchtlich verringert werden, da nur ein einziger Hauptarm vorgesehen sein muß, so daß auch nur mehr ein einziger Hydraulikzylinder zum Betätigen des Hauptarmes erforderlich ist, was sich vorteilhaft auf die Kosten des Auslegers auswirkt. Zum anderen kann aber auch das Gewicht im Vergleich zum Fahrzeug der US 4 444 542 A beträchtlich reduziert werden, was insbesondere bei Holzbearbeitungsmaschinen, die sich im Wald und auf steilem und unwegsamen Gelände bewegen müssen, sehr wesentlich ist. Weiters bietet der erfindungsgemäße Ausleger noch den Vorteil, daß bestehende Ausleger an Fahrzeugen problemlos durch einen erfindungsgemäßen Ausleger ersetzt werden können, ohne daß besondere Änderungen der Lagerung des Hauptarmes am Fahrzeugrahmen erforderlich sind, da nach wie vor nur ein einziger Hauptarm vorgesehen ist, wogegen bei dem Fahrzeug nach der US 4 444 542 A eine zweite Lagerung für den getrennten Wipparm erforderlich ist. Schließlich wird eine Sichtbehinderung durch den zweiten Ausleger während der Arbeit vermieden.On the one hand, the technical effort can be considerably reduced, since only a single main arm has to be provided, so that only a single hydraulic cylinder is required to actuate the main arm, which has an advantageous effect on the costs of the boom. On the other hand, the weight can also be considerably reduced in comparison to the vehicle of US 4,444,542 A, which is very important in particular in the case of woodworking machines which have to move in the forest and on steep and rough terrain. Furthermore, the boom according to the invention also has the advantage that existing booms on vehicles can be easily replaced by a boom according to the invention without special changes in the mounting of the main arm on the vehicle frame being necessary, since only a single main arm is still provided, whereas the Vehicle according to US 4,444,542 A a second storage for the separate rocker arm is required. Finally, a visual obstruction by the second boom during work is avoided.

Die am Hauptarm befestigten zwei Wipparme können entweder gemeinsam oder unabhängig voneinander am Hauptarm verschwenkt werden. An einem Wipparm ist dabei z.B. ein Harversterkopf befestigt. Am anderen Wipparm befindet sich eine Vorrichtung, die als Fortbewegungshilfe eingesetzt werden kann. Dabei kann es sich beispielsweise um eine übliche Baggerschaufel oder um ein pfahlähnliches Werkzeug handeln, mit dem sich die Arbeitsmaschine an einem geeigneten Ort im Gelände abstützen kann, um z.B. eine größere Steigung oder ein Hindernis zu überwinden.The two rocker arms attached to the main arm can either be pivoted together or independently of one another on the main arm. For example, a Harverster head is attached to a rocker arm. On the other rocker arm there is a device that can be used as a locomotion aid. This can be, for example, a conventional excavator shovel or a pile-like tool with which the working machine can be supported at a suitable location in the field eg to overcome a steep incline or an obstacle.

Da sich die Fortbewegungshilfe an einem zweiten Wipparm befindet, ist das Werkzeug am ersten Wipparm nicht der Gefahr von Beschädigungen ausgesetzt und in seiner Einsatz fähigkeit auch in keiner Weise beschränkt.Since the locomotion aid is located on a second rocker arm, the tool on the first rocker arm is not exposed to the risk of damage and its use is in no way restricted.

In der US 4 797 051 A und der DE 27 14 613 Al sind Frontlader für Arbeitsfahrzeuge beschrieben. Um den An- und Abbau der Frontlader von den Arbeitsfahrzeugen möglichst einfach zu gestalten, sind an den Frontladern Abstellstützen befestigt, die im Betriebszustand hochgeklappt bzw. eingeschoben werden und somit funktionslos sind.Front loaders for work vehicles are described in US 4,797,051 A and DE 27 14 613 A1. In order to make the attachment and detachment of the front loaders from the work vehicles as easy as possible, parking supports are attached to the front loaders, which are folded up or pushed in during operation and are therefore inoperative.

Weitere vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der übrigen Unteransprüche.Further advantageous embodiments of the invention are the subject of the remaining subclaims.

Im folgenden wird eine vorteilhafte Ausführungsform der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert.An advantageous embodiment of the invention is explained in more detail below with reference to the drawings.

Es zeigt:

  • Fig. 1 teilweise einen erfindungsgemäßen Ausleger in Seitenansicht und
  • Fig. 2 eine Draufsicht auf einen erfindungsgemäßen Ausleger.
It shows:
  • Fig. 1 partially a boom according to the invention in side view
  • Fig. 2 is a plan view of a boom according to the invention.

In Fig. 1 ist eine Ausführungsform eines erfindungsgemäßen Auslegers schematisch dargestellt, wobei die Lagerung des Hauptarmes 1 am Fahrzeug sowie das Fahrzeug selbst nicht dargestellt sind, da es sich dabei um an sich übliche Lagerungen bzw. Fahrzeuge handeln kann, die für die vorliegende Erfindung nicht von besonderer Bedeutung sind. Bevorzugt ist der Ausleger 1 an einen an sich bekannten sogenannten Schreitbagger gelagert, dessen Spinnenbeine ausfahrbar sind und die einen sehr starken Niveauausgleich ermöglichen.In Fig. 1, an embodiment of a boom according to the invention is shown schematically, wherein the mounting of the main arm 1 on the vehicle and the vehicle itself are not shown, since it can be conventional bearings or vehicles that are not for the present invention are of particular importance. The boom 1 is preferably mounted on a so-called walking excavator known per se, the spider legs of which can be extended and which enable a very strong level compensation.

Wie in Fig. 1 zu sehen ist, besteht der erfindungsgemäße Ausleger aus einem Hauptarm 1, an dessen freiem Ende zwei Wipparme 2, 3 um eine Lagerachse 4 schwenkbar gelagert sind. Der Hauptarm 1 ist, wie an sich üblich, mit Hilfe eines Hydraulikzylinders 6 in Richtung des Doppelpfeiles 5 verschwenkbar.As can be seen in Fig. 1, the boom according to the invention consists of a main arm 1, at the free end of which two rocker arms 2, 3 are pivotally mounted about a bearing axis 4. Of the Main arm 1, as is usual, can be pivoted in the direction of double arrow 5 with the aid of a hydraulic cylinder 6.

Die Wipparme 2, 3 sind getrennt voneinander mit Hilfe von doppelt wirkenden Hydraulikzylindern 7, 8 verschwenkbar. Die Wipparme 2, 3 sind überdies teleskopartig verlängerbar, wobei der Wipparm 2 aus drei teleskopierbaren Elementen 2', 2" und 2"' besteht, wogegen der Wipparm 3 nur aus zwei teleskopierbaren Elementen 3' und 3" besteht. Das teleskopische Auseinander- und Zusammenschieben der Wipparme 2, 3 erfolgt auf an sich bekannte Weise über in den Zeichnungen nicht dargestellte Hydraulikzylinder.The rocker arms 2, 3 can be pivoted separately from one another by means of double-acting hydraulic cylinders 7, 8. The rocker arms 2, 3 are also telescopically extendable, the rocker arm 2 consisting of three telescopic elements 2 ', 2 "and 2"', whereas the rocker arm 3 consists of only two telescopic elements 3 'and 3 ". The telescopic apart and The rocker arms 2, 3 are pushed together in a manner known per se via hydraulic cylinders, not shown in the drawings.

Die Wipparme 2, 3 müssen nicht wie in den Zeichnungen dargestellt nebeneinander an fluchtenden Achsen 4 am Hauptarm 1 gelagert sein, sondern die Lagerstellen der Wipparme 2, 3 können unabhängig voneinander an beliebigen Stellen des Hauptarmes 1 liegen. Desweiteren können die Wipparme 2, 3 selbst aus mehreren, gelenkig miteinander verbundenen Teil-Wipparmen bestehen.The rocker arms 2, 3 do not have to be mounted next to one another on aligned axes 4 on the main arm 1, as shown in the drawings, but the bearing points of the rocker arms 2, 3 can lie independently of one another at any desired locations on the main arm 1. Furthermore, the rocker arms 2, 3 themselves can consist of several partial rocker arms articulated to one another.

Am Wipparm 2 ist ein nicht dargestellte Arbeitswerkzeug, z.B. ein Harvesterkopf, angeordnet. Am Wipparm 3, dessen Reichweite geringer ist als die Reichweite des Wipparmes 2, ist eine beliebige, nicht dargestellte Fortbewegungshilfe befestigt. Da erfindungsgemäß die Fortbewegungshilfe an einem getrennten Wipparm 3 befestigt ist, kann diese auch während eines Bearbeitungsvorganges zum Abstützen des Fahrzeuges herangezogen werden, um dem Fahrzeug eine bessere Standfestigkeit zu verleihen, was insbesondere bei vollständig ausgefahrenem Wipparm 2 von Vorteil ist.On the rocker arm 2 is a work tool, not shown, e.g. a harvester head arranged. Any travel aid, not shown, is attached to the rocker arm 3, the range of which is less than the range of the rocker arm 2. Since, according to the invention, the locomotion aid is attached to a separate rocker arm 3, it can also be used to support the vehicle during a machining operation in order to give the vehicle better stability, which is particularly advantageous when the rocker arm 2 is fully extended.

In einer alternativen in den Zeichnungen nicht dargestellten Ausführungsform können die beiden Wipparme 2, 3 auch miteinander verbunden und gemeinsam mit einem einzigen Hydraulikzylinder verschwenkbar sein, was zwar die Einsatzmöglichkeiten des erfindugnsgemäßen Auslegers etwas verringert, dafür aber eine kostengünstigere Variante ist. Diese Ausführungsform kann z.B. so zum Einsatz kommen, daß während eines Bearbeitungsvorganges mit dem Harvesterkopf der Wipparm 3 eingezogen ist. Zur Fortbewegung mit Hilfe des Wipparmes 3 hingegen ist der Wipparm 2 mit dem Harversterkopf eingezogen und der Wipparm 3 nach Bedarf mehr oder weniger weit ausgefahren.In an alternative embodiment, not shown in the drawings, the two rocker arms 2, 3 can also be connected to one another and pivoted together with a single hydraulic cylinder, which may reduce the possible uses of the boom according to the invention, but is a more cost-effective variant. This embodiment can be used, for example, so that the rocker arm 3 is retracted during a machining operation with the harvester head. For Locomotion with the help of the rocker arm 3, however, the rocker arm 2 is retracted with the Harversterkopf and the rocker arm 3 extended more or less as needed.

Der erfindungsgemäße Ausleger kommt bevorzugt bei Fahrzeugen zur Holzbearbeitung in schwierigem oder steilem Gelände zum Einsatz. Er kann allerdings auch bei Fahrzeugen für andere Verwendungszwecke, z.B. für Baufahrzeuge, vorteilhaft zum Einsatz kommen, wenn z.B. in schwierigem oder steilem Gelände eine zusätzliche Abstützung des Auslegers wünschenswert ist.The boom according to the invention is preferably used in vehicles for woodworking in difficult or steep terrain. However, it can also be used for vehicles for other purposes, e.g. for construction vehicles, can be used advantageously if e.g. additional support of the boom is desirable in difficult or steep terrain.

Zusammenfassend kann eine Ausführungsform der Erfindung beispielsweise wie folgt dargestellt werden:In summary, an embodiment of the invention can be represented as follows, for example:

Ein Ausleger für ein Holzbearbeitungsfahrzeug weist an einem Fahrzeugrahmen einen schwenkbar befestigten Hauptarm 1 und einen am Hauptarm 1 schwenkbar befestigten Wipparm 2 auf. An diesem Wipparm 2 ist z.B. ein Harvesterkopf befestigt. Am Hauptarm 1 ist ein weiterer Wipparm 3 gelagert, an dem eine Fortbewegungshilfe, z.B. eine Baggerschaufel, befestigt ist. Die Fortbewegungshilfe und der Harvesterkopf können auf diese Weise unabhängig voneinander zum Einsatz kommen, ohne daß die Funktion des Harvesterkopfes beeinträchtigt wird.A boom for a woodworking vehicle has a pivotable main arm 1 and a rocker arm 2 pivotally attached to the main arm 1 on a vehicle frame. On this rocker arm 2 is e.g. a harvester head attached. Another rocker arm 3 is mounted on the main arm 1, on which a locomotion aid, e.g. an excavator shovel is attached. The locomotion aid and the harvester head can be used independently of one another in this way without the function of the harvester head being impaired.
