Description
Die Erfindung betrifft eine Schnellverbindung für Rohre, die im Blas- oder Spülversatzbetrieb des Kohlenbergbaues Anwendung finden.The invention relates to a quick connection for pipes that are or flushing operation of the coal mining industry.
Unter den zahlreichen bisher bekanntgewordenen Rohrschnellverschlüssen befinden sich Kupplungen, bei denen durch Keile der Anpreßdruck zwischen den Rohrbunden herbeigeführt wird. Auch bei der Erfindung wird der Keil als Anpreßelement benutzt.Among the numerous quick-release pipe fasteners that have become known to date there are couplings where the contact pressure between the pipe coils is maintained by means of wedges is brought about. In the invention, too, the wedge is used as a pressure element.
Es ist eine Rohrschnellverbindung bekannt, bei der die um i8o° versetzten beiden Wangen eines Bügels in besonders ausgebildeten Schlitzen zwei Anzugskeile aufnehmen. Die Keile sind nicht starr miteinander verbunden und müssen einzeln bei Herstellung der Verbindung angezogen werden.A quick pipe connection is known in which the staggered by 180 ° two cheeks of a bracket in specially designed slots two wedges take up. The wedges are not rigidly connected to one another and must be used individually Establishing the connection must be tightened.
Bei einer anderen Kupplung durchdringen zwei U-förmige, mit rippenartigen Erhöhungen versehene Keile eine die Rohrenden umschließende Kupplungshülse. Durch Antreiben der Keile wird ein axial gerichteter Dichtungsdruck zwischen den Rohrenden erzeugt. Die Bügelkeile sind lose Bestandteile der Kupplung.In another coupling, two U-shaped, with rib-like penetrations Wedges provided with elevations and a coupling sleeve surrounding the pipe ends. By Driving the wedges is an axially directed sealing pressure between the pipe ends generated. The bracket wedges are loose components of the coupling.
Die Nachteile dieser Kupplungen werden bei einer anderen, ebenfalls bekannten Rohrschnellverbindung dadurch beseitigt, daß die beiden, den Anpreßdruck herbeiführenden Keile, starr in Form eines U-förmigen Bügels miteinander verbunden sind und in Schlitzen einer das Rohrende umschließenden Rohrmuffe geführt werden, wobei die Führungswangen der Ringmuffe besondere Ansätze aufweisen, die in Nuten des Keilbügels eingreifen. Hierdurch wird ein gleichmäßiger Anzug und eine unverlierbare Verbindung des Keilbügels mit der Ringmuffe garantiert.The disadvantages of these clutches are compounded by another, as well known pipe quick connection eliminated in that the two, the contact pressure inducing wedges, rigidly connected to one another in the form of a U-shaped bracket and are guided in slots in a pipe socket surrounding the pipe end, wherein the guide cheeks of the ring sleeve have special approaches that are in grooves of the wedge bracket engage. This creates an even suit and a captive one Connection of the wedge bracket with the ring socket guaranteed.
Während bei den bekannten Schnellverbindungen mit Keilen neben den eigentlichen Anpreßkeilen noch andere als Führung und Widerlager für die Keile dienende Bauelemente notwendig sind, betrifft die Erfindung eine Schnellkupplung, bei der Keile und Widerlager in einem einzigen Bauelement vereinigt sind. Dies wird dadurch erreicht, daß ein aus einem U-ähnlichen Profil gebogener U-förmiger Bügel mit keilartig verlaufenden Innenflächen die entsprechend ausgebildeten Bunde der Rohrenden umschließt und zusammenpreßt.While with the known quick connections with wedges next to the actual pressure wedges are used as guides and abutments for the wedges Components are necessary, the invention relates to a quick coupling in which Wedges and abutments are combined in a single component. This is because of this achieved that a U-shaped bracket bent from a U-like profile with a wedge-like extending inner surfaces enclosing the correspondingly formed collars of the pipe ends and press together.
In der Zeichnung ist in den Abb. i bis 6 ein Ausführungsbeispiel der Rohrschnellkupplung gemäß der Erfindung wiedergegeben, und zwar zeigt Abb. i eine Stirnansicht, Abb. 2 einen Längsschnitt, Abb.3 eine Seitenansicht in geöffneter Kupplungsstellung, Abb.4 den zugehörigen Querschnitt in Höhe der Rohrmitte, Abb. 5 eine Seitenansicht in Verschlußstellung und Abb. 6 den zugehörigen Querschnitt in Höhe der Rohrmitte.In the drawing, in Figs. I to 6, an embodiment of the Quick pipe coupling reproduced according to the invention, namely Fig. I shows a Front view, Fig. 2 is a longitudinal section, Fig. 3 is a side view in the open Coupling position, Fig. 4 the corresponding cross-section at the height of the middle of the pipe, Fig. 5 shows a side view in the closed position and FIG. 6 shows the associated cross section at the height of the center of the pipe.
Die seitlichen Innenflächen 2 und 3 des U-förmigen Bügels i hintergreifen die der Dichtungsseite abgewandten Flächen der Bundringe 4 und 5. Die Innenfläche 3 verläuft keilförmig zum Scheitelpunkt des Bügels. Durch Antreiben des Keilbügels mittels Hammerschlägen auf den am Scheitelpunkt angebrachten Amboß 6 werden die Bunde 4 und 5 zusammengepreßt und durch die schräge Ausbildung der Preßfläche des Bundes 5 zentriert. Das Lösen der Kupplung geschieht durch Hochdrücken des Keilbügels mit Hilfe des Ansatzes 7. Sobald sich der kleinere Bund 5 innerhalb der Aussparungen io und i i des Keilbügels befindet, kann das Anschlußrohr mit der durch die Begrenzungsstollen 8 und 9 auf dem größeren Bund 4 festgehaltenen Kupplung frei zu Boden fallen.Reach behind the lateral inner surfaces 2 and 3 of the U-shaped bracket i the surfaces of the collars 4 and 5 facing away from the sealing side. The inner surface 3 runs in a wedge shape to the apex of the bracket. By driving the wedge bracket by means of hammer blows on the anvil 6 attached to the apex, the Collars 4 and 5 pressed together and due to the inclined design of the pressing surface of the Federal 5 centered. The coupling is released by pushing up the wedge bracket using approach 7. As soon as the smaller collar 5 is within the recesses io and i i of the wedge bracket is located, the connecting pipe with the through the limiting cleats 8 and 9 fall freely to the ground on the clutch held on the larger collar 4.
