Schaufelvorsatz für einen Gabelstapler Bucket attachment for a forklift
Beschreibungdescription
Die Erfindung betrifft einen Schaufelvorsatz für einen Gabelstapler nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bucket attachment for a forklift truck according to the preamble of claim 1.
Ein derartiger bekannter Schaufelvorsatz für einen Gabelstapler wird an der vorderen Montageplatte des Gabel¬ staplers montiert und vom Gabelstapler bewegt. Dabei erfolgt die Betätigung der Schaufel auf hydraulischem Wege, indem die Kippbewegung der Schaufel durch zusätzlich installierte Hydraulikzylinder gesteuert wird. Die Betätigung dieser zusätzlichen Zylinder ist in dem Hydrauliksteuersystem des Gabelstaplers integriert. Dazu ist im Bedienungsbereich des Gabelstaplers für seine verschiedenen Staplerfunktionen ein zusätzlicher Bedienungshebel für die Kippbewegung der Schaufel angeordnet.Such a known scoop attachment for a forklift truck is mounted on the front mounting plate of the forklift truck and moved by the forklift truck. The bucket is actuated hydraulically by controlling the tilting movement of the bucket by means of additionally installed hydraulic cylinders. The actuation of these additional cylinders is integrated in the hydraulic control system of the forklift. For this purpose, an additional operating lever for the tilting movement of the bucket is arranged in the operating area of the forklift for its various forklift functions.
Derartige Schaufelvorsätze für einen Gabelstapler mit den zugehörigen Hydrauliksystemen zum Betätigen der Schaufel können nur vom Hersteller der Gabelstapler oder nach seinen P-länen ausgeführt werden und sind auch jeweils nur für einen Gabelstaplertyp konzipierbar.Such scoop attachments for a forklift with the associated hydraulic systems for actuating the scoop can only be carried out by the manufacturer of the forklift or according to his plans and can also only be designed for one type of forklift.
Es ist weiterhin bekannt, einen Schaufelvorsatz für einen Gabelstapler der oben beschriebenen Art mit hydrau¬ lischer Betätigung so auszubilden, daß die Zinken des Gabelstaplers vom Grundrahmen der Halterung für die Schaufel aufgenommen und gegen ein Verrutschen gesichert werden können, was den Vorteil hat, daß kein Umrüsten der Gabelzin¬ ken erforderlich ist und dieser Vorsatz für alle Gabelstapler passend ist. Der Nachteil, daß für den Betrieb des Schaufel¬ vorsatzes eine zusätzliche hydraulische Steuerung in das Hydraulik-Steuersystem des Gabelstaplers integriert werden muß, was mit einem erheblichen Aufwand verbunden ist, bleibt jedoch auch bei diesem Schaufelvorsatz bestehen. 1 -It is also known to design a bucket attachment for a forklift of the type described above with hydraulic actuation so that the tines of the forklift can be picked up by the base frame of the holder for the bucket and secured against slipping, which has the advantage that none Retrofitting the fork tines is required and this attachment is suitable for all forklifts. The disadvantage that an additional hydraulic control must be integrated into the hydraulic control system of the forklift for the operation of the scoop attachment, which is associated with a considerable effort, remains with this scoop attachment. 1 -
Die der Erfindung zugrundeliegende Aufgabe besteht daher darin r einen Schaufelvorsatz für einen Gabelstapler nach dem Oberbegriff des Patentanspruchs 1 so auszubilden, daß er in Verbindung mit bestehenden Gabelstaplertypen benutzt werden kann, ohne daß an den Gabelstaplern bauliche Veränderungen vorgenommen werden müssen.The underlying object of the invention is therefore to develop a bucket attachment for a forklift truck according to the preamble of claim 1 so that it can be used in conjunction with existing forklift truck types without having to make structural changes to the forklift trucks.
Diese Aufgabe wird gemäß der Erfindung durch die Ausbildung gelöst, die im Kennzeichen des Patentanspruchs 1 angegeben ist.This object is achieved according to the invention by the training specified in the characterizing part of patent claim 1.
Bei dem erfindungsgemäßen Schaufelvorsatz ist aufgrund der rein mechanischen Betätigung der Schaufel keine Hydraulik für das Auslösen der Kippbewegung der Schaufel und das Rückführen der Schaufel erforderlich. Zum Auslösen der Kippbewegung muß lediglich der Niederhalter so betätigt werden , daß dessen Arretierung mit der Schaufel gelöst wird. Während der dadurch ausgelösten Kippbewegung der Schaufel wird die RückholZugfeder gespannt, so daß die Schaufel nach dem Entleeren über die Rückholzugfeder selbsttätig in ihre Ausgangslage zurückkehrt und dort durch den Niederhalter wieder arretiert wird.In the blade attachment according to the invention, due to the purely mechanical actuation of the blade, no hydraulics are required to trigger the tilting movement of the blade and to return the blade. To trigger the tilting movement, the hold-down device only has to be actuated so that its locking is released with the shovel. During the tipping movement of the bucket triggered thereby, the return tension spring is tensioned, so that the bucket automatically returns to its starting position after emptying via the return tension spring and is locked there again by the hold-down device.
Da somit alle Einrichtungen zum Betätigen der Schaufel am Schaufelvorsatz selbst vorgesehen sind, und der Schaufel¬ vorsatz alle Funktionen zum Steuern der Schaufel selbst bewirkt, kann der erfindungsgemäße Schaufelvorsatz an beliebigen Gabelstaplertypen angebracht werden, ohne daß am Gabelstapler selbst bauliche Veränderungen vorgenommen werden müssen.Since all the devices for actuating the bucket are thus provided on the bucket attachment itself, and the bucket attachment performs all functions for controlling the bucket itself, the bucket attachment according to the invention can be attached to any type of forklift truck without having to make any structural changes to the forklift itself.
Besonders bevorzugte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Schaufelvorsatzes sind Gegenstand der Patentansprüche 2 bis 10.Particularly preferred developments and refinements of the blade attachment according to the invention are the subject of claims 2 to 10.
Im folgenden wird der anhand der zugehörigen Zeichnung ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben. Es zeigenA particularly preferred exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawing. Show it

Das in der Zeichnung dargestellte Ausführungsbeispiel des erfindungsgemäßen Schaufelvorsatzes für einen Gabelstap¬ ler umfaßt im wesentlichen eine Schaufel 11, die um eine Achse schwenk- oder kippbar in einer Halterung gehalten ist, die einen Grundrahmen 2, beispielsweise in Form einer Grundplatte, umfaßt, die mit Aufnahmen 1 für die Gabelzinken des Gabelstaplers versehen ist. Die Aufnahmen 1 für die Gabelzinken sind so angeordnet und so bemessen, daß der Schaufelvorsatz für alle Gabelstaplertypen geeignet ist.The embodiment shown in the drawing of the scoop attachment according to the invention for a forklift essentially comprises a scoop 11 which is held in a holder which can be pivoted or tilted about an axis and which comprises a base frame 2, for example in the form of a base plate, which also includes Recordings 1 is provided for the forks of the forklift. The receptacles 1 for the forks are arranged and dimensioned so that the bucket attachment is suitable for all types of forklift trucks.
In der Halterung können Schaufeln verschiedenster Konstruktion gehalten sein, die auf dem Grundrahmen 2 schwenkbar, drehbar und insbesondere kippbar gelagert sind.Buckets of various designs can be held in the holder, which are pivotably, rotatably and in particular tiltably mounted on the base frame 2.
Auf dem Grundrahmen 2 ist ein Niederhalter 4 angebracht, der dazu dient, die Schaufel 11 in ihrer horizontalen Lage zu arretieren. Wie es insbesondere in Fig. 2 und Fig. 5 darge¬ stellt ist, besteht dieser Niederhalter 4 aus einem vertika¬ len Ständer, der um eine Achse in seinem Fußteil schwenkbar ist und mit einem in Richtung auf die Schaufel 11 vorstehen¬ den, am vorstehenden Teil abgeschrägten Klinkenelement 14 versehen ist, über das ein Rastelement der Schaufel 11 gleiten und einrasten kann. Der Niederhalter 4 ist durch eine Feder 10 beaufschlagt, die den Niederhalter in Richtung auf die Arretierungsposition vorspannt.A hold-down device 4 is attached to the base frame 2 and serves to lock the blade 11 in its horizontal position. As is shown in particular in FIGS. 2 and 5, this hold-down device 4 consists of a vertical stand which can be pivoted about an axis in its foot part and which projects in the direction of the blade 11 on projecting part of the beveled pawl element 14 is provided, over which a locking element of the blade 11 can slide and engage. The hold-down device 4 is acted upon by a spring 10, which prestresses the hold-down device in the direction of the locking position.
Am oberen freien Ende eines Hebels, der auf der Schwenkachse des Niederhalters 4 sitzt, ist ein Zugseil 5 zum Auslösen des - *t -At the upper free end of a lever, which sits on the pivot axis of the hold-down device 4, there is a pull rope 5 for triggering the - * t -
Niederhalters 4 angebracht, das in das Fahrerhaus des Gabelstaplers führt und an dem der Fahrer des Gabelstaplers ziehen kann, um die Arretierung der Schaufel 11 am Niederhal¬ ter 4 zu lösen, indem der Niederhalter 4 gegen die Kraft der Feder 10 aus der Ineingriffnahme mit der Schaufel 11 zurück¬ gezogen wird. Der Niederhalter 4 kann so ausgebildet sein, daß seine Bewegung nach hinten zu einer leichten Schwenkbewe¬ gung der Schaufel 11 führt, die mit einer Verlagerung ihres Schwerpunktes verbunden ist. Diese Schwenkbewegung der Schaufel 11 kann über einen zusätzlichen Hebel ausgelöst oder bewirkt werden. Diese Schwerpunktverlagerung löst die Kippbewegung der Schaufel 11 nach unten aus.Hold-down device 4 attached, which leads into the driver's cab of the forklift truck and on which the driver of the forklift truck can pull in order to release the locking of the bucket 11 on the hold-down device 4, in that the hold-down device 4 counteracts the force of the spring 10 from engaging with the Blade 11 is withdrawn. The hold-down device 4 can be designed in such a way that its rearward movement leads to a slight pivoting movement of the blade 11, which is associated with a shift in its center of gravity. This pivoting movement of the blade 11 can be triggered or effected via an additional lever. This shift in the center of gravity triggers the tilting movement of the blade 11 downward.
Die Schwerpunktverlagerung kann jedoch auch über ein leichtes Neigen der Zinken des Gabelstaplers nach unten unterstützt werden.The shift in the center of gravity can also be supported by slightly tilting the forks of the forklift downwards.
Wie es insbesondere in Fig. 3 dargestellt ist, ist zwischen der Schaufel 11 und der Halterung eine Rückholfeder 6 vorgesehen, die mit einem Spannschloß 7 zum Einstellen der Rückholkraft versehen ist und durch die Kippbewegung der Schaufel 11 nach unten gespannt wird. Die•Rückholkraft der Rückholfeder 6 ist so gewählt, daß die leere Schaufel 11 nach dem Abkippen in ihre Ausgangslage zum Arretieren durch die Niederhalter 4 zurückgeführt wird. Die Arretierungseinrich¬ tung des Niederhalters 4 kann dabei so ausgebildet sein, daß die Arretierung selbsttätig erfolgt.As is particularly shown in Fig. 3, a return spring 6 is provided between the blade 11 and the holder, which is provided with a turnbuckle 7 for adjusting the return force and is tensioned downward by the tilting movement of the blade 11. • the return force of the return spring 6 is so chosen that the empty bucket is returned after the tipping 11 to its initial position for locking by the holding-down device. 4 The locking device of the hold-down device 4 can be designed so that the locking takes place automatically.
Wie es insbesondere in Fig. 1 dargestellt ist, sind FuhrungsStangen mit verstellbaren Anschlägen 8 zum Einstellen des maximal möglichen Kippwinkels der Schaufel 11 so vorgese¬ hen, daß sie die Kippbewegung der Schaufel 11 begrenzen. Diese Anschläge 8 und damit der maximal mögliche Kippwinkel sind verstellbar ausgebildet. Eine Anschlagdämpfung 9 an auf den FuhrungsStangen gleitenden Ringen 15, die an der Schaufel 11 angebracht sind, dient zum Dämpfen des Anschlages 11 beim Erreichen des Kippgrenzwinkels. - s -As is shown in particular in FIG. 1, guide rods with adjustable stops 8 for setting the maximum possible tilt angle of the blade 11 are provided such that they limit the tilting movement of the blade 11. These stops 8 and thus the maximum possible tilt angle are adjustable. A stop damping 9 on the rings 15 sliding on the guide rods, which are attached to the blade 11, serves to dampen the stop 11 when the tilt limit angle is reached. - s -
Wie es insbesondere in Fig. 4 dargestellt ist, können die Gabelzinken in Aufnahmen 1 des Grundrahmens 2 der Halterung für die Schaufel 11 eingefahren werden. Knebel¬ schrauben 3, die am Grundrahmen 2 vorgesehen sind, dienen zur Sicherung der Gabelzinken gegenüber einem Verrutschen.As is shown in particular in FIG. 4, the fork tines can be retracted into receptacles 1 of the base frame 2 of the holder for the blade 11. Knebel¬ screws 3, which are provided on the base frame 2, serve to secure the fork tines against slipping.
Das oben beschriebene Ausführungsbeispiel des erfin- dungsgemäßen Schaufelvorsatzes für einen Gabelstapler wird in der folgenden Weise eingesetzt und benutzt. Zunächst wird der Schaufelvorsatz so am Gabelstapler angebracht, daß die Gabelstaplerzinken in die Aufnahmen 1 des Grundrahmens 2 einfahren. In dieser Position werden der Schaufelvorsatz und die Gabelzinken über die Knebelschraube 3 gegen ein Verrut¬ schen gesichert. Die Aufnahme der Gabelzinken im Grundrahmen 2 erfolgt dabei grundsätzlich in gleicher Weise wie die Aufnahme der Gabelzinken in einer Palette.The embodiment of the bucket attachment for a forklift according to the invention described above is used and used in the following manner. First, the bucket attachment is attached to the forklift so that the forklift tines move into the receptacles 1 of the base frame 2. In this position, the bucket attachment and the fork tines are secured against slipping via the toggle screw 3. The forks in the base frame 2 are basically picked up in the same way as the forks in a pallet.
Das Seil 5 zum Auslösen des Niederhalters 4 wird am Hebel 13 zum Betätigen des Niederhalters eingehängt und in das Führerhaus des Gabelstaplers geführt.The rope 5 for triggering the hold-down device 4 is hung on the lever 13 for actuating the hold-down device and guided into the driver's cab of the forklift.
Nach dem Beladen der Schaufel 11 löst der Gabelstapler¬ fahrer von seinem Fahrersitz aus mit Hilfe des Zugseiles 5 die Arretierung der Schaufel 11 am Niederhalter 4, indem er am Zugseil 5 zieht, woraufhin die Schaufel 11 um ihre Schwenkachse nach unten abkippt. Diese Kippbewegung kann durch eine Verlagerung des Schwerpunktes beim Lösen der Arretierung mit Hilfe eines Hebels oder durch ein leichtes Neigen der Zinken des Gabelstaplers nach unten unterstützt werden. Die beiden Fuhrungss angen mit ihren verstellbaren Anschlägen 8 begrenzen den Kippwinkel und ermöglichen über die Anschlagdämpfung 9, beispielsweise in Form von Druckfe¬ dern, eine Dämpfung des Anschlages. Während des Abkippens der Schaufel 11 wird die RückholZugfeder 6 gespannt, so daß nach Entleeren der Schaufel 11 die Schaufel 11 wieder in ihrer Ausgangsposition zurückgezogen wird, in der sie durch den Niederhalter 4 selbsttätig wieder arretiert wird. Die Arretierung der Schaufel 11 schnappt selbsttätig wieder ein.After loading the shovel 11, the forklift driver releases the locking of the shovel 11 on the hold-down device 4 from his driver's seat with the aid of the pull rope 5 by pulling on the pull rope 5, whereupon the shovel 11 tilts downward about its pivot axis. This tilting movement can be supported by shifting the center of gravity when releasing the lock with the help of a lever or by slightly tilting the forks of the forklift downwards. The two guideways with their adjustable stops 8 limit the tilt angle and enable damping of the stop via the stop damping 9, for example in the form of compression springs. During the tipping of the blade 11, the return spring 6 is tensioned so that after the blade 11 has been emptied, the blade 11 is pulled back into its starting position, in which it is automatically locked again by the hold-down device 4. The Locking the bucket 11 automatically snaps back into place.
Da die Federkraft der Rückholzugfeder über das Spann¬ schloß 7 einstellbar ist, ist eine Anpassung an verschiedene Schaufelgrößen und -formen möglich.Since the spring force of the return spring can be adjusted via the turnbuckle 7, an adaptation to different blade sizes and shapes is possible.
Der erfindungsgemäße Schaufelvorsatz für einen Gabel¬ stapler hat somit den Vorteil, daß für seine Bedienung nur mechanische Elemente benötigt werden, so daß er für den Einsatz bei allen Gabelstaplertypen geeignet ist, ohne daß an den Gabelstaplern selbst irgendwelche bauliche Veränderungen, beispielsweise zusätzliche hydraulische oder sonstige Steuereinrichtungen vorgesehen werden müssen. The scoop attachment according to the invention for a forklift truck thus has the advantage that only mechanical elements are required for its operation, so that it is suitable for use with all types of forklift trucks without any structural changes, for example additional hydraulic or other, on the forklift trucks themselves Control devices must be provided.
