Description
Die Erfindung betrifft einen Rohrleitungsmolch zum zentrierten Durchfahren von geraden und gekrümmten Rohrleitungen, mit mindestens zwei bezüglich der Molchachse einander gegenüberliegenden, zur Anlage an der Rohrleitungsinnenwand bestimmten Anlageelementen.The The invention relates to a pipeline pig for centered passage straight and curved Pipelines, with at least two with respect to the pig axis each other opposite, to the plant on the pipe inner wall certain investment elements.

Demgegenüber ist es die Aufgabe der Erfindung, einen Rohrleitungsmolch der eingangs genannten Art derart weiterzubilden, dass die Mitte zwischen den zwei Anlageelementen auch beim Durchfahren eines gekrümmten Rohrleitungsabschnitts möglichst in der Rohrleitungsachse liegt.In contrast, is It is the object of the invention, a pipeline pig of the beginning so-called type in such a way that the middle between the two system elements as possible when driving through a curved pipe section lies in the pipeline axis.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen quer zur Molchachse verschiebbar geführten Schieber, an dem die zwei einander gegenüberliegenden Anlageelemente gehalten sind.These The object is achieved by a slidably guided transversely to the pig axis slide on which the two opposite ones Investment elements are held.
In einem gekrümmten Rohrleitungsabschnitt wird der Schieber aus seiner bezüglich der Molchachse zentrierten Position in Richtung auf den Krümmungsmittelpunkt des gekrümmten Rohrleitungsabschnitts ausgelenkt. Aus dieser Auslenkung des Schiebers kann z.B. die Krümmung der Rohrleitung berechnet werden.In a curved one Pipe section is the slide from his relative to the pig axle centered position toward the center of curvature of the curved pipe section deflected. From this displacement of the slider, e.g. the curvature of the Piping be calculated.
Bei bevorzugten Ausführungsformen ist der Schieber rechtwinklig zur Molchachse verschiebbar geführt und liegen die zwei Anlageelemente bezüglich der Molchlachse einander diametral gegenüber.at preferred embodiments the slide is guided at right angles to the pig axis and slidably lie the two investment elements with respect to the pig slaughter each other diametrically opposite.
Vorzugsweise sind die Anlageelemente am Schieber in Richtung auf die Molchachse gegen die Wirkung einer Rückstellkraft auslenkbar gelagert, d.h. radial nach außen vorgespannt. Die Rückstellkraft der zwei Anlageelemente kann durch eine zwischen den Anlageelementen wirkende Druckfeder oder jeweils durch eine zwischen Anlageelement und Schieber wirkende Rückstellfeder gegeben sein.Preferably are the abutment elements on the slide in the direction of the pig axle against the effect of a restoring force deflectably supported, i. biased radially outward. The restoring force of the two investment elements can by a between the investment elements acting compression spring or in each case by a between contact element and slider acting return spring be given.
Vorzugsweise sind am Molch erste Sensoren, die die Auslenkung der Anlageelemente, insbesondere relativ zum Schieber, und die Auslenkung des Schiebers relativ zur Molchachse erfassen, und, sofern die Anlageelemente als Rollen ausgebildet sind, zweite Sensoren vorgesehen, die die Drehung der Anlageelemente erfassen.Preferably are the first sensors on the pig, the deflection of the system elements, in particular relative to the slider, and the deflection of the slider detect relative to the pig axis, and, if the investment elements are designed as rollers, second sensors provided, which the Detect rotation of the system elements.
Bei bevorzugten Ausführungsformen weist der Molch mehrere Schieber auf, die in unterschiedlichen Querrichtungen verschiebbar geführt sind und deren Anlageelemente auf gleicher axialer Höhe des Rohrleitungsmolchs angeordnet sein können. Je mehr Schieber vorgesehen sind, desto präziser kann die Rohrleitungsgeometrie vermessen werden. Zwei Schieber sind bevorzugt zueinander rechtwinklig verschiebbar geführt, so dass ein rechtwinkliges Messkoordinatensystem definiert ist.at preferred embodiments the pig has several slides, which are in different transverse directions slidably guided are and their investment elements at the same axial height of the pipeline pig can be arranged. The more sliders are provided, the more precise the pipe geometry can be be measured. Two slides are preferably perpendicular to each other slidably guided, such that a rectangular measurement coordinate system is defined.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale erfindungsgemäß jeweils einzeln für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further Advantages of the invention will become apparent from the description and the Drawing. Likewise the above-mentioned and the features further mentioned according to the invention individually for themselves or to several in any combination use. The embodiments shown and described are not as final enumeration but rather have exemplary character for the description the invention.
