Abstract

The system for rapidly connecting hydraulic lines (1, 3) comprises an eccentric (8) which presses against a yoke (7) when turned. The yoke slides along a shaft and moves one half (6) of the coupling, which is fitted over the shaft, until it engages with the other half (5), which is fixed.

Description

Es gibt Kupplungen für Hydraulikschläuche (1), die aus zwei Kupplungshälften (2) bestehen. Über diese werden Schläuche (1) oder Leitungen (3) miteinander verbunden und getrennt, ohne dass beim Kupplungs- oder Entkupplungsvorgang Flüssigkeit 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 einer Kupplung, die mit einander verschraubt wird, dauert ca. 10 Minuten. Da bei hydraulischen Antrieben immer mindestens zwei Leitungen und somit auch zwei Kupplungen vorhanden sind, ist die doppelte Zeit notwendig.There are couplings for hydraulic hoses ( 1 ), which consists of two coupling halves ( 2 ) consist. These are used to make hoses ( 1 ) or lines ( 3 ) and separated without liquid leaking during the coupling or uncoupling process. These have the disadvantage that they are from a certain size, since there is often a residual pressure in the lines are very difficult to couple. The coupling process of a coupling, which is bolted together, takes about 10 minutes. Since there are always at least two lines and thus also two couplings in hydraulic drives, twice this time is necessary.

Sinn der Erfindung ist es, eine Vorrichtung zu bauen, um einen Kupplungsvorgang in wenigen Sekunden mit erheblich geringerem Kraftaufwand durchzuführen.sense The invention is to build a device to a coupling operation in a few seconds with considerably less effort.

Zu diesem Zweck wird eine Kupplungshälfte (5) an einem Teil, wie zum Beispiel einem Baggerausleger (4), befestigt. Die zweite Kupplungshälfte (6), die an einem Schlauch (1) befestigt ist, wird gegen die fest angebaute Hälfte (5) fluchtgemäß über eine Führungswelle (9) ausgerichtet. Dazu wird diese in eine Führungsgabel (7) gelegt. Diese sorgt dafür, dass eine genaue lineare Führung erfolgen kann. Über eine Exenterscheibe (8), die genau mittig fluchtend gegenüber beiden Kupplungshälften (2) am Ende einer Kupplungshälfte (6) angeordnet ist und gegen eine Führungswelle (9) drückt, wird mit einer Drehung im Uhrzeigersinn über 180 Grad das Hebelgesetz angewandt und beide Kupplungshälften (2) ineinander verschoben. In dieser Stellung ist eine Arretierung (11) angebracht. Der Kupplungsvorgang ist somit abgeschlossen. Der erfindungsgemäße Vorteil der Vorrichtung besteht noch darin, dass beide Kupplungshälften nach dem Zusammenfügen kraftschlüssig miteinander verbunden sind und somit der bekannte hohe Verschleiß des Schließmechanismus, besonders bei pulsierenden Drücken der herkömmlichen Kupplungen, ausgeschlossen wird. Das Lösen der Kupplung (2) erfolgt in umgekehrter Reihenfolge, durch Drehen der Exenterscheibe gegen den Uhrzeigersinn.For this purpose, a coupling half ( 5 ) on a part, such as an excavator boom ( 4 ), fastened. The second coupling half ( 6 ) attached to a hose ( 1 ) is fixed against the fixed half ( 5 ) in alignment via a guide shaft ( 9 ). For this purpose, this is in a guide fork ( 7 ) placed. This ensures that an accurate linear guide can be made. Via an eccentric disc ( 8th ), which are exactly centered in relation to both coupling halves ( 2 ) at the end of a coupling half ( 6 ) and against a guide shaft ( 9 ), the lever law is applied with a clockwise rotation over 180 degrees and both coupling halves ( 2 ) shifted into each other. In this position is a lock ( 11 ) appropriate. The coupling process is thus completed. The advantage of the device according to the invention consists in the fact that both coupling halves are positively connected with each other after assembly and thus the known high wear of the locking mechanism, especially with pulsating pressures of the conventional couplings, is excluded. Disconnecting the clutch ( 2 ) is done in reverse order by turning the eccentric disc counterclockwise.
