Abstract[English]
A system improving diamond core drilling sample extraction using a lifter case with a longitudinal split that enables removal without rotation. The case expands by deformation for easy core sample extraction with minimal disaggregation. During drilling, a closure ring prevents expansion. The lifter case attaches to a core tube via interlocking serrations with a longitudinal key or keyway to prevent rotation. Compatibility with industry-standard tubes is achieved using an adapter with matching serrations, a key/keyway, and internal threads designed for non-compatible tubes. This design simplifies operation while ensuring secure, efficient extraction of core samples.[French]
L'invention concerne un système améliorant l'extraction d'échantillons de carottage diamant à l'aide d'un boîtier extracteur présentant une fente longitudinale qui permet un retrait sans rotation. Le boîtier se dilate par déformation pour permettre une extraction d'échantillon de carottage facile avec une désagrégation minimale. Pendant le carottage, une bague de fermeture empêche l'expansion. Le boîtier extracteur se fixe à un tube central par l'intermédiaire de dentelures à interverrouillage présentant une rainure de clavetage ou clé longitudinale pour empêcher la rotation. La compatibilité avec des tubes standard de l'industrie est obtenue à l'aide d'un adaptateur présentant des dentelures correspondantes, une clé/rainure de clavetage et des filetages internes conçus pour des tubes non compatibles. Cette conception simplifie le fonctionnement tout en garantissant une extraction sûre et efficace d'échantillons de carottage.
