Abstract

The tool changeover system for a load handling vehicle is based on hydraulically operated locking pins which are moved inwards automatically to engage a pair of adaptor plates with the tool attached. An actuator piston for swinging the tool can be mounted between an intermediate plate carrying the tool and the adaptor plates. The tool may be a pair of lifting forks in which case an additional piston can be mounted between the forks and the intermediate plate to swing the forks sideways. The tool may be a dredging shovel or gripping jaws, and operating mechanism are incorporated. The end of the tool arm is forked, with the pins sliding through the forks into and out of engagement.

Description

Umschlaggerät mit einer hydraulischen VerriegelungsvorrichtungMaterial handling machine with a hydraulic locking device

zum Ankuppeln eines pendelnd aufhängbaren Werkzeuges an einen Werkzeugstiel Die Erfindung betrifft ein Umschlaggerät mit einer hydraulischen Verriegelungsvorrichtung zum Ankuppeln eines pendelnd aufhängbaren Werkzeuges an einen Werkzeugstiel.For coupling a tool that can be suspended in a pendulum manner to a tool handle The invention relates to a handling machine with a hydraulic locking device For coupling a tool that can be suspended in a pendulum manner to a tool handle.

Umschlaggeräte, die mit punktförmig aufgehängten Greifwerkzeugen ausgerüstet sind, werden in den verschiedensten Verwendungsbereichen, z.B. Holz, Schrott, Baustellen und dergleichen eingesetzt. Es gibt jedoch Arbeiten, die aufgrund der bis jetzt nicht vorhandenen Möglichkeit, die pendelnd aufgehängten Werkzeuge gegen ein starr angelenktes Werkzeug im Schnellkuppelverfahren zu wechseln, nicht durchgeführt werden konnten.Handling equipment equipped with gripping tools suspended at points are used in a wide variety of areas, e.g. wood, scrap, construction sites and the like used. However, there is work that has been done so far non-existent possibility of the pendulum suspended tools against a rigid one to change the articulated tool using the quick coupling method cannot be carried out could.

Der Erfindung liegt die Aufgahe zugrunde, den Arbeitsbereich und damit die Rentabilität eines solchen Gerätes zu erhöhen.The invention is based on the task, the work area and thus to increase the profitability of such a device.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein Adapter, an dem ein Werkzeug starr anlenkbar -ist, an dem Werkzeugstiel mittels der Verriegelungsvorrichtung starr ankuppelbar ist.According to the invention this object is achieved in that an adapter, on which a tool can be rigidly articulated, on the tool handle by means of the locking device can be rigidly coupled.

Der mit der Erfindung erzielbare Vorteil besteht darin, daß es möglich ist, Umschlaggeräte, die mit pendelnd aufgehängten Werkzeugen ausgerüstet sind, mit einem starr angelenkten Werkzeug zu versehen und dadurch den Anwendungsbereich und somit die Rentabilität des Gerätes zu erhöhen.The advantage achieved with the invention is that it is possible is, handling equipment that is equipped with pendulum suspended tools, to be provided with a rigidly articulated tool and thereby the area of application and thus profitability of the device.

Weitere Merkmale der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung gekennzeichnet.Further features of the invention are in the subclaims and the marked below.

Die Erfindung wird anhand der Beispiele der Zeichnung näher erläutert. In der Zeichnung zeigt: Fig. 1 den erfindungsgemäßen Adapter mit Staplergabel, Fig. 2 den Adapter mit Löffel und Fig. 3 den Adapter mit starr angelenktem Greifwerkzeug.The invention is explained in more detail with reference to the examples in the drawing. The drawing shows: FIG. 1 the adapter according to the invention with a fork lift truck, FIG. 2 the adapter with spoon and FIG. 3 the adapter with rigidly hinged gripping tool.

Das Ankuppeln der Werkzeuge mit dem Adapter 1 erfolgt durch gezieltes Ansteuern des Werkzeugstieles 2 an das Werkzeug vom Fahrerhaus des Gerätes aus. Ist die gewünschte Position erreicht, wird der Adapter 1 über ein axial angeordnetes Bolzenpaar 3 vom Fahrerstand aus verriegelt, so daß eine starre Verbindung zwischen demAdapter 1 und dem Werkzeugstiel 2 besteht.The coupling of the tools with the adapter 1 is carried out in a targeted manner Controlling the tool handle 2 on the tool from the cab of the device. Once the desired position has been reached, the adapter 1 is axially arranged Bolt pair 3 locked from the driver's cab, so that a rigid connection between the adapter 1 and the tool handle 2.

Die Starrheit der Verbindung wird z.B. dadurch erreicht, daß der Adapter eine Verdrehsicherung, z.B. eine Gabel aufweist, die, nachdem die Verbolzung durchgeführt ist, ein Drehen um das Bolzenpaar 3 verhindert.The rigidity of the connection is achieved, for example, by the fact that the adapter an anti-rotation device, e.g. a fork, which, after the bolting is carried out is prevented from rotating about the pair of bolts 3.

Es lassen sich auch starre Verbindungen durch einen Formschluß erreichen, bei denen dann die Bolzenverbindung nicht als Drehpunkt dient, sondern nur zur Sicherung und Aufnahme einer Kraftkomponente.Rigid connections can also be achieved by means of a form fit, in which the bolt connection then does not serve as a fulcrum, but only for securing and absorption of a force component.

An dem Adapter 1 kann z.B. eine Staplergabel 4, die mindestens über einen Zylinder 5 in ihrer Waagrechten gehalten wird und um ihre vertikale Achse mittels ein Zylinders 6 geschwenkt werden kann, befestigt sein.On the adapter 1, for example, a forklift fork 4, which at least over a cylinder 5 is held horizontally and about its vertical axis can be pivoted by means of a cylinder 6, be attached.

Durch Ankuppeln des um 1800 gedrehten Adapters 1 an den Werkzeugstiel 2 ist es z.B. möglich, einen Löffel 7 zur Aufnahme von verschiedenartigsten Materialen als Tief- oder Hochwürfel zu verwenden.By coupling the adapter 1 turned by 1800 to the tool handle 2 it is e.g. possible to use a spoon 7 to hold a wide variety of materials to use as a low or high cube.

Bei den beiden zuvor genannten Beispielen ist an dem Adapter 1 zum Schwenken des Werkzeuges ein Schwenkzylinder 5 angelenkt.In the two examples mentioned above, the adapter 1 for Pivoting the tool a pivot cylinder 5 is articulated.

Bei Verwendung eines starr angelenkten Greifwerkzeuges, das um seine Achse drehbar ist, und mit den verschiedenartigsten Schalen ausgerüstet sein kann, u.a. als Schere 8 für den Schrotteinsatz, weist der Adapter 1 einen Drehmotor 9, der ein Verdrehen des Werkzeuges um eine Achse parallel zur Längsachse des Werkzeugstieles 2 erlaubt, und eine dazugehörige Hydraulikmitteldurchführung auf.When using a rigidly hinged gripping tool that is around his The axis is rotatable and can be equipped with a wide variety of shells, e.g. as scissors 8 for the use of scrap, the adapter 1 has a rotary motor 9, rotating the tool about an axis parallel to the longitudinal axis of the tool handle 2 allowed, and an associated hydraulic fluid lead-through.
