| 221 | Trépan pour sondage | EP81810301.2 | 1981-07-22 | EP0044817A2 | 1982-01-27 | Treyvaud, René |
Le corps de trépan (2) est fixé à l'extrémité inférieure d'un train de tiges engagées dans le trou de sondage (1). Le bossage (4) faisant saillie à l'intérieur de la cavité sphérique (3) supporte l'arbre (6) qui porte l'élément rotatif (11) de forme sphérique maintenu en place par l'écrou (7). La surface extérieure de l'élément (11) est garnie de particules dures, par exemple des grains de métal dur ou des éléments de diamant. Par suite de l'entraînement du corps de trépan (2) autour de son axe et du frottement de la surface (18), l'élément rotatif (11) tourne nécessairement sur l'arbre (6), de sorte que l'ensemble de la face inférieure du trou (1) est attaquée par abrasion. |

| Un trepan de forage dans la roche possede des couteaux a aplanir (38) sur l'extremite d'attaque d'une tete de trepan amovible (20) pour aplanir le fond d'un trou et des couteaux aleseurs (54, 56) s'etendant sur la longueur du trepan. Des couteaux et des fentes de reception des couteaux possedent des configurations en forme de queue d'aronde pour emprisonner les couteaux dans les fentes. Des coins de positionnement des couteaux sont disposes dans le fond des fentes. Des passages lateraux (82, 83, 84) communiquent avec un passage central de boue pour amener le fluide boueux vers des orifices entre les couteaux. Le passage central de boue possede une configuration de venturie (24C) et des passages longitudinaux (86) amenages dans le trepan s'etendent vers le bas de l'amont du venturie pour intersecter ou communiquer avec les passages lateraux. Un aplanisseur de noyau (102) est monte par un mandrin a collet (100) dans le passage central pres de sa sortie sur l'extremite d'attaque du trepan pour aplanir un noyau forme sur le fond du trou entre les extremites internes des couteaux d'aplanissage (38) sur la face extreme. | ||||||
