Abstract

La présente invention concerne un dispositif pour retenir des corps creux cylindriques en permettant une rotation axiale. Ce dispositif qui sert à retenir des corps creux cylindriques à grande épaisseur de paroi et très importante longueur se caractérise en ce qu'il comprend des plateaux circulaires d'appui 9 prévus à chaque extrémité du corps creux 10 pour le retenir de manière centrée, les plateaux d'appui 9 comprenant des organes d'appui 7 réglables en direction radiale par rapport au corps creux 10. Les plateaux circulaires 9 sont reliés à des tourillons 6 qui reposent sur des supports à galets équipés de galets d'appui 8. Les supports à galets sont montés respectivement sur un chariot 5 mobile dans le sens de l'axe du corps 10. Un dispositif d'entraînement 2, 3 monté sur une console 1 coopère avec le dispositif de serrage pour maintenir le corps creux centré. L'invention s'applique à la construction des réacteurs.The present invention relates to a device for retaining cylindrical hollow bodies while allowing axial rotation. This device which is used to retain cylindrical hollow bodies with a large wall thickness and very long length is characterized in that it comprises circular support plates 9 provided at each end of the hollow body 10 to retain it in a centered manner, the support plates 9 comprising support members 7 adjustable in the radial direction relative to the hollow body 10. The circular plates 9 are connected to journals 6 which rest on roller supports fitted with support rollers 8. The supports with rollers are mounted respectively on a carriage 5 movable in the direction of the axis of the body 10. A drive device 2, 3 mounted on a bracket 1 cooperates with the clamping device to keep the hollow body centered. The invention applies to the construction of reactors.
