Abstract
Description
Die Erfindung richtet sich auf eine Vorrichtung zum Kuppeln und Entkuppeln der Anschluflenden von Druckmittelleitungen, insbesondere von Hydraulikleitungen, mit einer ortsfesten und einer auf einem beweglichen Schlitten bewegbaren Kupplungshälfte, die durch eine Kolben-/Zylindereinheit in Kuppel- und/oder Entkuppelstellung bewegbar ist, insbesondere an Werkzeugschnellwechseleinrichtungen von Bau- oder Landmaschinen der im Oberbegriff des Anspruches 1 angegebenen Gattung.The Invention is directed to a device for coupling and uncoupling the connecting ends of pressure medium lines, especially hydraulic lines, with one stationary and one movable on a movable carriage Coupling half, by a piston / cylinder unit in the coupling and / or uncoupling position is movable, in particular on quick tool changing devices from Construction or agricultural machinery specified in the preamble of claim 1 Genus.
Die Erfindung geht aus von dem DE-202 12 445-U des Anmelders, das eine gattungsgemäße Vorrichtung zeigt, die sich durch eine von dem Druckkolben selbst betätigbare mechanische Verriegelung auszeichnet, wobei hydraulische Kupplungen auch aus der DE-697 17 080-T oder der DE-692 10 405-T bekannt sind.The Invention is based on the applicant's DE-202 12 445-U, the one generic device shows, which can be actuated by a pressure piston itself mechanical locking features, hydraulic clutches are also known from DE-697 17 080-T or DE-692 10 405-T.
Ausgehend von den Vorteilen des gattungsbildenden Standes der Technik, nämlich eine sichere Fixierung der Hydraulikschläuche im Kupplungszustand zu gewährleisten, ist es Aufgabe der Erfindung, eine Sicherung zu der bekannten mechanischen Sicherung zu schaffen, die zusätzliche mechanische Fixierelemente entbehrlich macht.outgoing of the advantages of the generic state of the art, namely one Secure fixation of the hydraulic hoses in the coupling condition guarantee, it is an object of the invention to provide a fuse to the known mechanical Creating backup that extra makes mechanical fixing elements unnecessary.
Mit einer Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß der Schlitten in der Kupplungsstellung durch den Druckkolben, dessen Druck durch ein entsperrbares Druckhalteventil gehalten ist, in der Verriegelungsstellung fixierbar ist.With a device of the type described above, this task thereby according to the invention solved, that the Carriage in the coupling position by the pressure piston, the Pressure is held in by an unlockable pressure maintaining valve the locking position can be fixed.
Es hat sich gezeigt, daß es in gewissen Anwendungsfällen vorteilhaft ist, eine hydraulische Fixierung über den Stellzylinder zu bewirken. Wird der Druck im Stellzylinder nach Ausübung des Schließvorganges gehalten, wird die Schließstellung mit Sicherheit fixiert.It has been shown to be in certain applications It is advantageous to effect a hydraulic fixation via the actuating cylinder. The pressure in the actuating cylinder after the closing process is carried out held, the closed position fixed with certainty.
Erst durch das Öffnen des Druckhalteventiles und Absenken des Schließdruckes ist dann ein Öffnen der Kupplung möglich.First by opening of the pressure control valve and lowering the closing pressure is then an opening of the Coupling possible.
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Dabei kann es vorteilhaft sein, wenn das Druckhalteventil vom Steuerstand eines damit ausgerüsteten Gerätes betätigbar ist .refinements the invention emerge from the subclaims. It can be advantageous if the pressure control valve can be operated from the control station of a device equipped with it ,
Wegen der Möglichkeit, die gekuppelten Hydraulikleitungen im Fließzustand zu halten, ist in weiterer Ausgestaltung der Erfindung vorgesehen, daß die hydraulischen Leitungskupplungen ohne eigene Trennsicherung, wie eine Kugelsi cherung od. dgl., ausgebildet sind.Because of The possibility, Keeping the coupled hydraulic lines in the flow state is in Another embodiment of the invention provided that the hydraulic Cable couplings without their own isolating fuse, like a ball fuse or the like. Are formed.

Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. Grundsätzlich kann dieses Ventil auch als zusätzliche Sicherheit bei Konstruktionen eingesetzt werden, wie sie in der gattungsgemäßen Gebrauchsmuster- bzw. in der nicht vorveröffentlichten entsprechenden europäischen Patentanmeldung beschrieben sind.Of course, the described embodiment of the invention is still in many respects change without leaving the basic idea. In principle, this valve can also be used as additional security in constructions such as are described in the generic utility model or in the corresponding European patent application, which has not been previously published.
