Title
(EN) DEVICE AND METHOD IN RESPECT OF ROCK BORING
(FR) DISPOSITIF ET PROCÉDÉ DE FORAGE DE ROCHE
Abstract
(EN)
A boring machine (1) for driving a drill string (8), wherein the boring machine includes: a driving head (6) being movable in an axial direction towards respectively from a holding table (5) for axially driving the drill string (8), a rotator (9) for driving the drill string (8), a drill string chuck (10), at the holding table (5), a second key grip device (12) at the rotator (9). A first sensor arrangement (13) in the region of the holding table (5) for detecting a first rotational position of a key grip 14; 24 of a drill string component (7), a second sensor arrangement (15) for detecting a second rotational position of the second key grip device (12), and a memory (17) for storing data representing the second rotational position. The invention also relates to a method.
(FR)
L'invention concerne une machine de forage (1) pour entraîner un train de tiges (8), la machine de forage comprenant : une tête d'entraînement (6) qui peut se déplacer dans une direction axiale respectivement depuis une table de maintien (5) pour entraîner axialement le train de tiges (8), un rotateur (9) pour entraîner le train de tiges (8), un mandrin de train de tiges (10), au niveau de la table de maintien (5), un second dispositif de prise de clé (12) au niveau du rotateur (9). Un premier agencement de capteur (13) dans la région de la table de maintien (5) pour détecter une première position de rotation d'une prise de clé (14 ; 24) d'un élément de train de tiges (7), un second agencement de capteur (15) pour détecter une seconde position de rotation du second dispositif de prise de clé (12), et une mémoire (17) pour stocker des données représentant la seconde position de rotation. L'invention concerne également un procédé.
