Abstract

The high-pressure hose connection comprises a union for an implement, a hose and a profile insert piece fixed to the union. A hose end is fitted over the insert piece, with a clamping sleeve round the hose end. The sleeve (4) has an extension (5) beyond the insert piece (2) and fitting round the hose (10) so as to form a further grip for the latter. This extension forms with the hose an annular safety chamber (8), connected by throttle drillings (7) to atmosphere.

Description

Hochdruckschlauchverbindung High pressure hose connection

Die Erfindung betrifft eine Hochdruckschlauchverbindung mit einem Anschlußstutzen für ein Gerät, eine Armatur oder einen zweiten Schlauch, einem am Anschlußstutzen festen, profilierten Einschubstück, einem über das Einschubstück geschobenen Schlauchende und einer das Schlauchende umgreifenden Klemmhülse.The invention relates to a high pressure hose connection with a Connection piece for a device, a fitting or a second hose, an am Connection piece fixed, profiled slide-in piece, one over the slide-in piece pushed hose end and a clamping sleeve encompassing the hose end.

Hoehdruekschlauchverbindungen der genanntn Art sind allgemein bekaiint, auch solche mit einer die Klemmhülse umgebenen Schutzmanschette (DE-OS 2 536 017).High pressure hose connections of the type mentioned are generally known, also those with a protective sleeve surrounding the clamping sleeve (DE-OS 2 536 017).

Bei Hochdruckschlauchverbindungen ist eine Schwachstelle die Verbindung vom Schlauch zu den metallischen Ansehlußstücken. Besondere Belastungen werden auf diese Verbindung durch ständige Druckwechsel und ständige Biegebewegungen aushebt, wie sie z. 3. bei handbedienten hydraulischen Werkzeugen vorkommen. Hierbei ist neben der allgemeinen Betriebssicherheit vor allem die Unfallsicherheit bei Schadensfällen von Bedeutung, da beim Ausreißen der Schlauchverbindung, das üblicherweise am Ende des Klemmbereichs erfolgt, das umherpeitschende Schlauchende und verspritzendes Hydraulikmedium eine erhebliche Gefahr darstellen. Die allgemein bekannten Schlauchverbindungen weisen keine gegen diese Gefahr gerichteten Merkmale auf. Die bereits bekannte Schutzmanschette ist allein gegen äußere Hitzeeinwirlcungen wirksam und erfüllt damit nur eine Brandschutzfunktion für Brennstoffleitungen. Sie nimmt keine wesentlichen Druck- oder Zugkräfte auf.In the case of high-pressure hose connections, a weak point is the connection from the hose to the metallic connection fittings. Special loads are on removes this connection through constant pressure changes and constant bending movements, how they z. 3. occur with hand-operated hydraulic tools. Here is In addition to general operational safety, above all accident safety in the event of damage important because when the hose connection is torn out, this usually ends at the end of the clamping area, the whipping hose end and the splashing one Hydraulic medium represent a significant risk. The well-known hose connections do not have any features directed against this danger. The already known protective sleeve is only effective against external heat effects and thus only fulfills a fire protection function for fuel lines. It does not absorb any significant compressive or tensile forces.

Der Erfindung liegt die Aufgabe zugrunde, eine Hochdruckschlauchverbindung zu schaffen, die neben den für die sichere Verbindung vom Schlauch zum Anschlußstück vorgesehenen Teile zusätzliche Merkmale hat, die die Belastungen am Ende des Klemmbereichs herabsetzen und die bei einem Ausreißen oder Abreißen des Schlauchs Fclge- bzw. Unfallschäden verhindern.The invention is based on the object of a high-pressure hose connection to create the next to the secure connection from the hose to the connector provided parts has additional features that the loads at the end of the clamping range reduce the risk of damage if the hose is torn off or torn off. Prevent accidental damage.

Die Aufgabe wird durch die in den beiden Ansprüchen genannten Kennzeichen in gleicher Weise vollständig erfüllt. Oberhalb des Klemmbereichs des Schlauchendes befindet sich eine weitere Klemmstelle, die das Ende des Klemmbereichs am Schlauchende von Biegebewegungen entlastet, und die selber im ormalbetrieb keine Längskräfte aufnehmen muß. Bei Schäden im Klemmbereich hält sie jedoch das Schlauchende bis zum Absinken des anstehenden Druckes in Längsrichtung fest. Das während dieser Zeit an der defekten Verbindung zwischen Schlauchende und Einschubstück bzw. Klemmhülse austretende 51 wird im Sicherheitsraum aufgefangen und tritt durch die Drosselbohrungen auf ungefährliche Weise aus.The object is achieved by the characteristics mentioned in the two claims fully met in the same way. Above the clamping area of the hose end there is another clamping point, which is the end of the clamping area at the end of the hose relieved of bending movements, and no longitudinal forces even in normal operation must take up. In the event of damage in the clamping area, however, it will hold the end of the hose up to to decrease the pressure in the longitudinal direction. That during this time at the defective connection between the hose end and the insertion piece or clamping sleeve exiting 51 is caught in the security room and passes through the throttle bores in a safe way.

ari ist jeweils ein Anschlußstutzen 1 mit einem Einschubstück 2 verbunden, das ein Tannenbaumprofil aufweist und in das Schlauchende 3 hineinragt. Um Schlauchende 3 und Einschubstück 2 greift eine Klemmhülse 4, die einstückig aufgewalzt oder aufgepresst oder in Schellenform oder als Halbschalen zusammengezogen ist.ari a connection piece 1 is connected to an insert piece 2, which has a Christmas tree profile and protrudes into the tube end 3. At the end of the hose 3 and insert piece 2 engages a clamping sleeve 4, which is rolled or pressed on in one piece or pulled together in the form of a clamp or as half-shells.

In Fig. 1 hat die Klemmhülse 4 eine Verlängerung 5, an deren Ende sich eine zusätzliche Klemmstelle 6 befindet.

The extension 5 is with throttle holes 7 and forms a safety space 8 with the hose 10.

In Fig. 2 wird die Klemmhülse 4 von einer Schutzmanschette 9 umgeben, die oberhalb der Klemmhülse 4 eine zusätzliche Klemmstelle 6 am Schlauch aufweist. Die Schutzmanschette 9 ist ebenfalls mit Drosselbohrunen 7 versehen und bildet mit der Klemmhülse 4 und dem Schlauch 10 einen Sicherheitsraum 8.In Fig. 2 the clamping sleeve 4 is surrounded by a protective sleeve 9, which has an additional clamping point 6 on the hose above the clamping sleeve 4.
