Description
Gegenstand der Erfindung bildet ein beispielsweise zur Aufnahme von Längenänderungen von Rohrleitungen dienendes dehnbares Federrohr mit schraubenförmig verlaufenden Wellen oder ringförmig in sich geschlossenen Parallelwellen und ein- oder umgelegten Versteifungskörpern. Bei den bekannten Vorrichtungen dieser Art sind die Versteifungskörper so ausgebildet, daß sieThe subject of the invention is, for example, for recording changes in length Extensible spring tube used by pipelines with helical ones Waves or ring-shaped, self-contained parallel waves and inserted or folded over Stiffeners. In the known devices of this type, the stiffening body are designed so that they
ίο lediglich ein Durchdrücken bzw. die gegenseitige Verschiebung der einzelnen Wellen verhindern, wobei das Federrohr sowohl auf Biegung als auch auf Dehnung beansprucht werden kann. Insbesondere wird bei längeren Federrohren, welche zur Aufnahme großer axialer Hübe erforderlich sind, der Über- oder Unterdruck des im Innern herrschenden Mediums dazu beitragen, das Federrohr auszuknicken.ίο only a push through or the mutual Prevent shifting of the individual shafts, with the spring tube on both Bending as well as stretching can be stressed. In particular, it is used for longer Spring tubes, which are required to accommodate large axial strokes, the overpressure or underpressure of the inside Medium contribute to buckling the spring tube.
Um dies zu verhüten, sind bei dem Federrohr gemäß der Erfindung die Versteifungskörper als Gleitschuhe ausgebildet, welche durch einen besonderen, vom Federrohr unabhängigen Führungskörper geführt werden.In order to prevent this, in the spring tube according to the invention, the stiffening bodies are designed as sliding shoes, which be guided by a special guide body that is independent of the spring tube.
Das Federrohr kann daher nur eine rein axiale Bewegung machen und ist außerdem vor frühzeitigem Durchscheuern geschützt, da die Gleitschuhe die einzelnen Wellen stets in gleicher Entfernung von dem Führungskörper halten.The spring tube can therefore only make a purely axial movement and is also Protected against early chafing, as the sliding shoes always keep the individual shafts in keep the same distance from the guide body.
In den Abb. 1 bis 3 sind verschiedene Federrohre in beispielsweiser Ausführungsform zur Darstellung gebracht. In Figs. 1 to 3, various spring tubes are shown in an exemplary embodiment.
Abb. ι veranschaulicht mehrere Federrohre in Schrauben- und Ringwellenform mit innen oder außen angeordneten Gleitschuhen. In den Wellen des Federrohres α sind ein oder mehrere Gleitschuhe b angeordnet, welche in einem Führungskörper c leicht beweglich eingepaßt sind. Der Gleitschuh b besitzt eine Ringwulst d, welche in die Wellen des Federrohres eingreift. Die Gleitschuhe werden, je nachdem es die Konstruktion bedingt, innen oder außen am Federrohr angebracht und können aus einem Stück bestehen oder aus mehreren Teilen zusammengesetzt sein. Ebenso kann der Führungskörper eine beliebige Zweckform erhalten und beispielsweise als Schubstange, Prisma o. dgl. ausgebildet sein.Fig. Ι illustrates several spring tubes in screw and ring wave form with sliding shoes arranged on the inside or outside. In the shafts of the spring tube α one or more sliding shoes b are arranged, which are fitted in a guide body c so that they can move easily. The sliding shoe b has an annular bead d which engages in the shafts of the spring tube. Depending on the design, the sliding shoes are attached to the inside or outside of the spring tube and can consist of one piece or be composed of several parts. Likewise, the guide body can have any functional shape and can be designed, for example, as a push rod, prism or the like.
Abb. 2 zeigt eine Ausführungsform, bei welcher die Gleitschuhe als Verschraubungen ausgebildet sind, so daß beispielsweise einzelne Federrohrelemente durch den Gleitschuh selbst druckfest miteinander verbunden werden können.Fig. 2 shows an embodiment in which the sliding blocks as screw connections are designed so that, for example, individual spring tube elements through the sliding shoe can even be connected to each other in a pressure-proof manner.
Abb. 3 zeigt eine Ausführungsform der Gleitschuhe mit eingelegten Kugeln, um den Gleitwiderstand auf ein Minimum zu beschränken. Fig. 3 shows an embodiment of the sliding blocks with inserted balls to the To keep sliding resistance to a minimum.
