要約
(EN)
Sealing performance is improved in a sliding gap of a rotating valve (38), and the rotating valve (38) is rotated smoothly when a roller bit (31) is exchanged. A valve housing portion (35) is formed in a rear portion of a bit housing portion (34) which forms an opening on a front surface of a main cutter spoke (21). A rotating valve (39), which is a rotating body, is rotatably disposed in the valve housing portion (35). A drilling reaction force is supported by projecting and moving a bit case (41) that has the roller bit (31) built therein from a removable passage (39) which is formed in the rotating valve (38) to the bit housing portion (34) and fixing the bit case using a cotter member (38). Thereby, the sliding gap of the rotating valve (39) is disposed in the bit housing portion (34) and the valve housing portion (35), and is covered by the bit case (41).

La présente invention concerne un procédé et un dispositif permettant d'améliorer la performance d'étanchéité dans l'écart de coulissement d'une valve rotative (38) et d'assurer une rotation régulière de la valve rotative (38) lors du remplacement d'un trépan à molettes (31). Une partie de logement de valve (35) est formée à l'arrière d'une partie de logement de trépan (34) qui est conçue avec une ouverture sur la surface avant d'un rayon principal de tête de coupe (21). Une valve rotative (39), qui constitue un corps rotatif, est disposée rotative dans la partie de logement de valve (35). Une force de réaction de forage est supportée par le biais d'un boîtier de trépan (41) faisant saillie et se déplaçant, et dans lequel est intégré le trépan à molettes (31) depuis un passage amovible (39) qui est formé dans la valve rotative (38) jusqu'à la partie de logement de trépan (34), et qui fixe le boîtier de trépan à l'aide d'un élément de clavette (38). Ainsi, l'écart de coulissement de la valve rotative (39) est situé dans la partie de logement de trépan (34) et la partie de logement de valve (35), et est recouvert par le boîtier de trépan (41).

 回動バルブ(38)の摺動隙間におけるシール性を向上させ、ローラビット(31)の交換時に回動バルブ(38)をスムーズに回動させる。主カッタスポーク(21)の前面に開口形成されたビット収容部(34)の後部に、バルブ収容部(35)を形成し、このバルブ収容部(35)に回動体である回動バルブ(39)を回動自在に配置し、ローラビット(31)を内装したビットケース(41)を、回動バルブ(38)に形成された着脱通路(39)からビット収容部(34)に突出移動してコッタ部材(38)により固定し掘削反力を支持させる。これにより、回動バルブ(39)の摺動隙間をビット収容部(34)とバルブ収容部(35)とに配置して、ビットケース(41)により覆う。
