Abstract
(EN)
A tube wall thickness measuring device includes an ultrasonic probe having a cylindrical part, a fixing part that fixes the cylindrical part, a movable moving part, and at least three expansion/contraction mechanisms connected to the fixing part and the moving part, and an urging member that connects the fixing part and the moving part. An expansion/contraction mechanism includes parallel leg parts on which wheels are arranged, rotatable first links and second links that connect the parallel leg parts and the fixing part, and a rotatable third link that connects the second link and the moving part. Where the urging member extends and the moving part separates from the fixing part, all parallel leg parts approach the cylindrical part. Where the urging member contracts and the moving part approaches the fixing part, all parallel leg parts separate from the cylindrical part.

L'invention concerne un dispositif de mesure d'épaisseur de paroi de tube comprenant une sonde ultrasonore dotée d'une partie cylindrique, d'une partie de fixation qui fixe la partie cylindrique, d'une partie mobile, et d'au moins trois mécanismes d'expansion/contraction reliés à la partie de fixation et à la partie mobile, ainsi qu'un élément de poussée qui relie la partie de fixation et la partie mobile. Un mécanisme d'expansion/contraction comprend des parties de branche parallèles sur lesquelles des roues sont agencées, des premier et de deuxième éléments de liaison rotatifs qui relient les parties de branche parallèles et la partie de fixation, et un troisième élément de liaison rotatif qui relie le deuxième élément de liaison et la partie mobile Lorsque l'élément de poussée s'étend et que la partie mobile se sépare de la partie de fixation, toutes les parties de branche parallèles s'approchent de la partie cylindrique Lorsque l'élément de poussée se contracte et que la partie mobile s'approche de la partie de fixation, toutes les parties de branche parallèles se séparent de la partie cylindrique
