Schnellwechselkupplung für HydraulikschläucheQuick-change coupling for hydraulic hoses

Es gibt Wechselkupplungen ( 1), die aus zwei Kupplungshälften ( 2 ) bestehen. Über diese werden Hydraulikschläuche oder Leitungen voneinander getrennt, ohne dass dabei Hydrauliköl austritt. Diese haben den Nachteil, dass sie ab einer gewissen Baugröße, da sich oft noch ein Restdruck in den Leitungen befindet, sehr schwer zu kuppeln sind. Der Kuppelvorgang bei Kupplungen, die mit einander verschraubt werden, dauert ca. 5 Minuten. Da bei hydraulischen Antrieben immer mindestens zwei Leitungen und somit auch zwei Kupplungen vorhanden sind, ist die doppelte Zeit notwendig. Sinn der Erfindung ist es, eine Kupplung derart zu verändern, dass Kuppelvorgänge wenige Sekunden mit erheblich geringerer Kraftaufwendung zu tätigen sind.There are interchangeable couplings ( 1 ) that consist of two coupling halves ( 2 ). These are used to separate hydraulic hoses or lines from one another without hydraulic oil leaking out. These have the disadvantage that, above a certain size, they are very difficult to couple because there is often residual pressure in the lines. The coupling process for couplings that are screwed together takes around 5 minutes. Since hydraulic drives always have at least two lines and therefore two couplings, twice as much time is required. The idea of the invention is to modify a coupling in such a way that coupling processes can be carried out in a few seconds with considerably less effort.

Zu diesem Zweck ist eine Führungshülse ( 3 ) vorgesehen, die auf der ersten Kupplungshälfte (2 ) befestigt wird. Diese weist einen Innendurchmesser auf, der dem Außendurch-For this purpose, a guide sleeve ( 3 ) is provided, which is attached to the first coupling half ( 2 ). This has an inner diameter that corresponds to the outer diameter

Anschläge ( 4 ) vorgesehen, um einen Hebel ( 5 ) anzusetzen. Auf der zweiten Kupplungshälfte ist ein Anschlag (6 ) vorgesehen.Stops (4) are provided to attach a lever (5). A stop (6) is provided on the second coupling half.

Wenn man den Hebel ( 5 ) ansetzt, wird die zweite Kupplungshälfte ( 2 ) in der passgenauen Führungshülse (3 ) zentriert, in die erste Kupplungshälfte ( 2) geschoben und verriegelt sich selbst. Ohne große Kraftaufwendung wird unter zu Hilfename des Hebelgesetzes der Kupplungsvorgang vollzogen. Der Entkupplungsvorgang geschieht in umgekehrter Reihenfolge. Hier wird über einen Hebel, der sich an die Anschläge (4 / 6) anlegt, zuerst die Verriegelungshülse verschoben und dann die beiden Kupplungshälften (2 ) getrennt.When the lever (5) is applied, the second coupling half (2) is centered in the precisely fitting guide sleeve (3), pushed into the first coupling half (2) and locks itself. The coupling process is carried out without great effort using the lever law. The uncoupling process takes place in the reverse order. Here, the locking sleeve is first moved using a lever that rests against the stops (4/6) and then the two coupling halves (2) are separated.
