Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur berührungslosen Nachführung von zerstörungsfreien Prüfeinrichtungen. Bei der Prüfung von Rohren, z.B. mittels Ultraschall, treten häufig dadurch Fehler auf, daß sich der Abstand zwischen Prüfeinrichtung und Prüfgut infolge der Bewegung des Prüfgutes ändert. Zur Vermeidung von Beschädigungen, die bei die Oberfläche berührenden Führungselementen auftreten könnten, wird erfindungsgemäß eine Einrichtung vorgeschlagen, die Sensoren verwendet, mit deren Hilfe, über eine elektronische Regeleinrichtung, der die Prüfsonde aufnehmende Rahmen an die Bewegung des Prüfgutes anpaßbar ist, mit dem Ziel der Konstanthaltung des Abstandes zwischen Prüfsonde bzw. -sonden und Prüfgutoberfläche.The invention relates to a method and a device for contactless tracking of non-destructive testing devices. When testing pipes, e.g. using ultrasound, errors often occur because the distance between the test device and the test item changes as a result of the movement of the test item. To avoid damage that could occur in the guide elements touching the surface, a device is proposed according to the invention that uses sensors, with the help of which, via an electronic control device, the frame receiving the test probe can be adapted to the movement of the test material, with the aim of Keeping the distance between the test probe or probes and the test object surface constant.
Description
Bei der Prüfung von Rohren mit Ultraschall oder der- 45
gleichen, z. B. zur Wanddickenmessung und/oder Feh-Ierprüfung wurden bisher Prüfeinrichtungen verwendet,
die durch Führungselemente an der Rohroberfläche
entlang geführt worden sind. Diese Führungselemente
unterlagen einem starken Verschleiß und außerdem tra- 50
ten häufig Meßfehler durch unerlässige bzw. unerwartete Bewegungen des Prüfgutes oder durch von den Führungselementen
abgelösten Partikeln z. B. Zunder auf.When testing pipes with ultrasound or the 45
same, e.g. B. for wall thickness measurement and / or fault testing, test devices have been used so far,
by guide elements on the pipe surface
have been led along. These guide elements
were subject to heavy wear and tear and also to 50
th frequently measurement errors due to unavoidable or unexpected movements of the test material or due to particles detached from the guide elements z. B. Tinder on.
Aufgabe der Erfindung ist es, eine Vorrichtung nach
dem Oberbegriff des Anspruchs 1 so weiterzubilden, 55
daß eine zerstörungsfreie Prüfung des Rohres ermöglicht wird, wobei der Abitand der Rohrprüfsonden zur
Rohroberfläche möglichst konstant bleibt.The object of the invention is to provide a device according to
to develop the preamble of claim 1 further, 55
that a non-destructive testing of the pipe is made possible, the Abitand of the pipe test probes for
The pipe surface remains as constant as possible.
Gelöst wird diese Aufgabe erfindungsgemäß durch
die Merkmale im Kennzeichendes Patentanspruchs 1. 60This object is achieved according to the invention by
the features in the characterizing claim 1. 60
Aus dem Anspruch 2 ergibt sich eine vorzugsweise
Ausgestaltung.From claim 2 there is preferably one
Design.
Durch die erfindungsgemäße Ausbildung der Vorrichtung tritt nunmehr kein Verschleiß von Führungsclementen
auf. Die erzielten Prüfdaten werden genauer &5
und unzulässige Fehleranzeigen werden wesentlich verringert. As a result of the design of the device according to the invention, there is now no wear of the guide elements. The test data obtained will be more precise & 5
and impermissible error messages are significantly reduced.
