Description
Es ist in der Materialprüfungstechnik bekannt, Prüflinge nacheinander in verschiedenen Proj ektionsrichtungen mit Röntgenstrahlen in der Weise zu durchleuchten, daß die Prüflinge mittels eines Transportbandes durch den Strahlenkegel einer Röntgenröhre geführt und während dieser Bewegung durch - einen Greifer in verschiedene Lagen gebracht werden. It is known in materials testing technology to test specimens one after the other x-rays in different projection directions in such a way that that the test specimens by means of a conveyor belt through the beam cone of an X-ray tube guided and during this movement by - a gripper in different positions to be brought.
Eine derartige Greiferanordnung läßt sich auf eine Vorrichtung zur Röntgendurchleuchtung langgestreckter Gebilde, z. B. Kabel, nach dem Durchlaufverfahren nicht übertragen. Erfindungsgemäß erreicht man in diesem Fall eine Durchleuchtung in verschiedenen Projektionsrichtungen in der Weise, daß man durch eine oder mehrere Rollen od. dgl. einen derartigen Hin- und Rücklauf des Gebildes am Untersuchungsort zur gesonderten Darstellung von je einem Durchleuchtungsbild von Hin- und Rücklauf bewirkt, daß am Untersuchungsort ein Querschnitt durch das Gebilde im Hinlauf ein Spiegelbild desselben Querschnittes im Rücklauf ist, wobei die Spiegeibildachse einen Winkel zwischen o und go0 mit der Richtung der Röntgenstrahlen bildet. Such a gripper arrangement can be applied to a device X-ray fluoroscopy of elongated structures, e.g. B. Cable, according to the continuous process not transferred. According to the invention, fluoroscopy is achieved in this case in different projection directions in such a way that one or more Rolls or the like such a back and forth movement of the structure at the examination site for the separate display of one fluoroscopic image each of the outward and return lines causes a cross section through the structure in the outward direction at the examination site The mirror image of the same cross-section is in the return, with the mirror image axis forms an angle between o and go0 with the direction of the X-rays.
Zur Veranschaulichung der Erfindung an einem besonders einfachen Ausführungsbeispiei dienen die Fig. I und 2. Einlauf H und Rücklauf K des Kabels werden über die Rolle R zwischen dem Leuchtschirm L und der senkrecht auf ihn strahlenden Röntgenstrahlenquelle S geführt. To illustrate the invention using a particularly simple one Exemplary embodiments are shown in FIGS. I and 2. Inlet H and return K of the cable are via the role R between the fluorescent screen L and the one radiating perpendicular to it X-ray source S out.
Fig. I stellt eine Aufsicht, Fig. 2 eine Seitenansicht aus der Blickrichtung B dar, wobei Leuchtschirm und Röntgenröhre im Vordergrund liegen, während die Rolle weiter zurückliegt. FIG. 1 shows a plan view, FIG. 2 shows a side view from the viewing direction B, with the fluorescent screen and X-ray tube in the foreground, while the role further back.
Bildet die Rollenebene einen Winkel 0 (in Fig. 2 450) mit der Leuchtschirmebene, wobei die Schnittgerade der beiden Ebenen parallel zu Hin- und Rücklauf des Kabels ist, und liegt im Querschnitt Q1 des HinlaufesH der PfeilP, der eine im Mittellängsschnitt des Kabels liegende röntgenstrahlenabsorbierende Struktur sei, inRichtung des Zentralstrahles, so steht er im Rücklauf K im Querschnitt Q2 um 2 <p ? (in Fig. 2 um 900) geneigt dazu. Im Rücklauf wird die Fehlerstelle F durch die Struktur verdeckt, während sie im Hinlauf zur Abbildung frei liegt. Wie aus Fig. 2 zu entnehmen ist, sind die Querschnitte von Hin- und Rücklauf Spiegelbilder in bezug auf die Rollenachse A, woraus sich die Verdoppelung des Winkels zwischen den Pfeilrichtungen gegenüber dem Winkel zwischen Achse und Pfeilrichtung ergibt. If the roller plane forms an angle 0 (in Fig. 2 450) with the screen plane, where the line of intersection of the two planes is parallel to the outward and return of the cable is, and lies in the cross-section Q1 of the trail H the arrow P, the one in the central longitudinal section The X-ray absorbing structure of the cable is, in the direction of the central ray, so it is in return K in cross section Q2 by 2 <p? (in Fig. 2 by 900) inclined to. In the return, the fault location F is covered by the structure, while it is exposed in the run-up to the figure. As can be seen from Fig. 2, the cross-sections are of back and forth mirror images with respect to the roller axis A, from which the doubling of the angle between the arrow directions compared to the angle between Axis and arrow direction results.
