Abstract

A plug-in connection between two pipe lengths of a riser in offshore drilling platforms has two annular grooves in the socket end of one and the spigot end of the other pipe. Four clamping segments are housed in the grooves of the socket end and can be moved radially to enter the grooves of the spigot end by four radial adjusting screws. This simplifies the making and breaking of a connection anduses a min. of moving parts. The working life of such a connection has been improved thereby.

Description

'tSseckverbinGung mit innen liegenden beweglichen Klemmseg-'' corner connection with internal movable clamping segment

inenten für Steigrchrleitungen (Riser)" Die Erfindung betrifft eine Steckverbindung mit innen liegenden beweglichen s e-m.seginenten für Steigrohrleitungen (Riser) bei off-shore-chrungen nach Kohlenwasserstoffen von einer schwimmenden Bohreinheit aus, wobei ein Rohrleitungsende als Nuffe und das andere als Einsteckteil ausgebildet ist. Inents for risers "The invention relates to a Plug connection with internal movable s e-m. Segments for riser pipes (Riser) for offshore drilling for hydrocarbons from a floating drilling unit with one end of the pipe designed as a socket and the other as a plug-in part is.

Bekannterweise haben Riser die Aufgabe, das Bohrgestänge, welches sich in ihnen befindet, zu führen und vor äußeren Einflüssen zu schützen und ferner die Bohrflüssigkeit zur schwimmenden Bohreinheit zurückzuführen.As is known, risers have the task of the drill pipe, which is located in them, to lead and to protect from external influences and further return the drilling fluid to the floating drilling unit.

Es sind Riser-Steckverbind1wngen bekannt geworden, die mit Hilfe mehrerer Verriegelungsspannhebel, die auf dem Umfang des Nuffenteils angeordnet sind, über entsprechend angeordnete bundartige Ansätze verspannt werden.Riser connectors have become known which, with the help of several Locking tension levers, which are arranged on the circumference of the socket part, over appropriately arranged collar-like approaches are braced.

Es sind auch Rohrsysteme (Marine-Riser) bekannt, die aus einzelnen Abschnitten (Riser-Joints) bestehen, die durch biegesteife Verbindungselemente bzw. Verschraubungen miteinander verbunden sind. Diese Verbindungen weisen lediglich am oberen oder unteren Teil eine flexible Verbindung auf (US-PS 3 601 187).There are also pipe systems (marine riser) known, which consist of individual There are sections (riser joints) that are connected by rigid connecting elements or Screw connections are connected to each other. These connections only point a flexible connection on the upper or lower part (US Pat. No. 3,601,187).

Es sind auch Rohrgestänge bekannt, die aus flexiblem Material bestehen (US-PS 2 606 003).There are also known pipe rods made of flexible material (U.S. Patent 2,606,003).

Diese Rohrgestänge weisen jedoch gegenüber Stahlkonstruktionen Fertigungsnachteile auf.However, these pipe rods have manufacturing disadvantages compared to steel constructions on.

In der DE-PS 25 1O ,4 ist bereits vorgeschlagen worden, Einzelabschnitte e n-Õ Achrsystems durch bewegliche Kugelgelenke zu verbinden.In DE-PS 25 1O, 4 has already been proposed, individual sections e n-Õ axle system to be connected by movable ball joints.

Es ist Aufgabe der Srfindz£g, eine Riser-Steckverbindung für off-shore-sohrunrel zu schaffen, mit der das Verriegeln bzw.It is the task of the Srfindz £ g to develop a riser connector for off-shore sohrunrel to create with which the locking or

Lösen der Verbindung vereinfacht wird.Releasing the connection is simplified.

Zur Lösung dieser Aufgabe wird erfindungsgemäß eine Steckverbindung vorgeschlagen9 wie sie in den Patentansprüchen beschrieben ist.According to the invention, a plug connection is used to solve this problem proposed9 as described in the claims.

Die Vorteile der erfindungsgemäßen Steckverbindung liegen in der Vereinfachung durch die Verringerung der Teilelemente. Es wird ferner ein größerer Umfangbereich des Einsteckteils der Verbindung erfaßt und damit die Haltefähigkeit der Steckverbindung erheblich verbessert.The advantages of the plug connection according to the invention lie in the simplification by reducing the number of sub-elements. It also becomes a larger scope of the plug-in part of the connection detected and thus the ability to hold the connector vastly improved.

In den beigefügten Zeichnungen ist eine mögliche Ausführungsform der erfindungsgemäßen Steckverbindung schematisch dargestellt.In the accompanying drawings, a possible embodiment of the Plug connection according to the invention shown schematically.

Es zeigen: Fig. 1 einen Schnitt durch die Steckverbindung Fig. 2 einen Querschnitt durch die Steckverbindung.They show: FIG. 1 a section through the plug connection, FIG. 2 a Cross section through the connector.

Wie in den Zeichnungen dargestellt, wird das Einsteckteil 2 in die Muffe 1 der Steckverbindung eingeschoben. Beide Teile werden durch querbewegliche Klemmsegmente (3) zusammengehalten, von denen mindestens acht in zwei übereinander liegenden Reihen derart angeordnet sind, daß sie querbeweglich in Nuten 4 der Muffe 1 geführt werden und im verriegelten Zustand der Steckverbindung in den Nuten 4a des Einsteckteiles 2 eingerastet sind, wobei Nuten 4 der Muffe 1 und Nuten 4a des Einsteckteiles 2 in ihrer Lage übereinstimmen.As shown in the drawings, the male part 2 is in the Sleeve 1 of the connector pushed in. Both parts are transversely movable by Clamping segments (3) held together, of which at least eight in two on top of each other lying rows are arranged so that they can move transversely in grooves 4 of the sleeve 1 and in the locked state of the connector in the grooves 4a of the plug-in part 2 are engaged, with grooves 4 of the sleeve 1 and grooves 4a of the Insert part 2 match in their position.

Die Klemmsegmente 3 sind an einem Ende mit einer Bohrung 5 versehen und besitzen as gegenüberliegenden Ende eine weitere Bohrung 8, in die der Zapfen 7 des Gelenkstückes 6 beweglich hineinragt, s ei im Gelenkstück 6 sich ebenfalls eine bohrung 9 befindet. In die Bohrungen 5 und 9 sind Bolzen 10 eingesetzt2 die in d Bchrungen 13 der Verbindungsstücke 11 eingreifen, wobei aus Montagegründen von den insgesamt vier Verbindungsstücken 11 ein Verbindungsstück geteilt ist.The clamping segments 3 are provided with a bore 5 at one end and have as the opposite end a further bore 8 into which the pin 7 of the joint piece 6 protrudes movably, s ei in the joint piece 6 is also a hole 9 is located. Bolts 10 are inserted into the bores 5 and 9 engage in the stanchions 13 of the connecting pieces 11, for assembly reasons of the total of four connecting pieces 11, one connecting piece is divided.

Die Verbindungsstücke 11 sind mit Bewegungsschrauben 12 versehen, mit deren Hilfe die Querbeweglichkeit der Klemmsegmente 3 über die Verbindungsstücke 11 erzielt wird.The connecting pieces 11 are provided with movement screws 12, with the help of which the transverse mobility of the clamping segments 3 via the connecting pieces 11 is achieved.

Zwei gegenüberliegende Stifte 14 ermöglichen eine genaue Lage von Muffe 1 und Einsteckteil 2 zueinander beim Zusammenbau der Verbindung.Two opposite pins 14 allow an exact location of Socket 1 and insert part 2 to each other when assembling the connection.

Vor dem Zusammenbau von Muffe 1 und Einsteckteil 2 werden die Klemmsegmente 3 mit Hilfe der Verbindungsstücke 11 und den Bewegungsschrauben 12 in den Nuten 4 der Muffe 1 in eine solche Lage gebracht, daß Muffe 1 und Einsteckteil 2 mühelos ineinandergesteckt werden können.Before the assembly of sleeve 1 and insert part 2, the clamping segments 3 with the help of the connecting pieces 11 and the movement screws 12 in the grooves 4 brought the sleeve 1 in such a position that sleeve 1 and insert part 2 effortlessly can be plugged into each other.

Nach dem Zusammenstecken von Muffe 1 und Einsteckteil 2 werden die Klemmsegmente 3 über die Verbindungsstücke 11 und die Bewegungsschrauben 12 quer nach innen bewegt, bis die Klemmsegmente 3 voll in den Nuten 4a des Einsteckteiles 2 eingerastet sind.After the socket 1 and insert part 2 have been plugged together, the Clamping segments 3 across the connecting pieces 11 and the movement screws 12 moved inward until the clamping segments 3 fully in the grooves 4a of the plug-in part 2 are engaged.

Der Zapfen 7 des Gelenkstückes 11, der in die Bohrung 8 der Klemmsefflmente 3 beweglich hineinragt, ermöglicht es, daß beim Querbewegen des Klemmsegmentes 3 keine Sperrung auftritt.The pin 7 of the joint piece 11, which in the bore 8 of the Klemmsefflmente 3 protrudes movably, makes it possible that when the clamping segment 3 no blocking occurs.
