摘要： The invention concerns a method and a device for directional drilling of a hole (3), in particular when drilling curved holes for mining, drift mining or similar, whereby a drill support (4) is used in the form of a flexible continuous drill tube with a proximal end and a distal end, that at the end of the drill support distal end is connected a down hole assembly (5) comprising a drill bit (13) for forming a drill string, which is fed into the gradually forming hole. To avoid and minimise the occurrence of "stick slip" during directional drilling, according to the method, the drill support (4) while drilling is taking place is held fixed at its proximal end against rotation outside the borehole and the rotating motion for indexing the drill bit (13) around an axis extending in the direction of drilling is performed in the area between the drill support's distal end and the drill bit while drilling is in progress.

摘要： A fluid-activated, percussive impact tool has a piston (46) therein that reciprocates longitudinally but not rotationally. The piston activates a wrap spring clutch (96) to rotate the drill steel. A removable splined nut (84) in combination with the tool's housing (42) restrains rotation of the piston, while permitting longitudinal reciprocation of the piston.

摘要： Un ensemble d'accouplement (16) transmet le mouvement rotatif d'un appareil à percussion (10) à un acier à fleurets. L'ensemble d'accouplement comprend un premier moyeu (18) sur lequel est formé une première surface cylindrique (24). Sur un second moyeu (20), couplé rotatif à l'acier à fleuret, est formée une seconde surface cylindrique (26). Ladite seconde surface cylindrique (26) est coaxiale avec ladite première surface cylindrique (24). Un ressort enroulé (17) vient au contact d'une partie à la fois de la première surface cylindrique (24) et de la seconde surface cylindrique (26), de manière que le mouvement rotatif relatif entre le premier moyeu (18) et le second moyeu (20) est possible dans un premier sens et empêché dans un second sens. L'accouplement (16) par ressort enroulé transmet le mouvement produit par l'ensemble tige du marteau perforateur ainsi qu'un agencement de tiges de plongeur.

摘要： Apparatus for drilling a bore hole comprises a hammer (3) and a series of dual wall drill tubes (2). The hammer (3) is supplied with compressed air and is for use in applying successive percussive blows to a percussive drill cutting bit for taking core samples from the bottom of the bore hole while drilling same. An upstanding rig (37) is provided at surface level to support the hammer (3) and drill tubes (2) and to transmit push-down or pull-up movement thereto. First means (32) indexes rotationally the bit for drilling purposes and is operable by a portion of the supply of air. Second means conducts from the bottom end of the bore hole that portion of air used by and exhausted from the percussive cutting bit (27) and having core particles entrained therein. Third means comprises an annular flushing jet (7) to direct a portion of air upwardly through a sampling tube (6) co-axial with the drill tube (2) and hammer (3) to induce a venturi to assist in conducting core particle entrained exhaust air upwardly.

摘要： Le dispositif comporte un corps de perforatrice (8), de forme générale cylindrique, relié par un tubage flexible (7) à une pompe à eau sous haute pression (11) placée sur un véhicule porteur (1) de faible hauteur. Un piston de frappe est monté mobile, rappelé élastiquement, dans le corps de perforatrice (8), et soumis à une haute pression pulsée d'eau de manière à être animé d'un mouvement de percussion contre une enclume porte-taillant, le tubage (7) transmettant simultanément au corps de perforatrice (8) un mouvement de rotation alternatif autour de son axe principal (A). Une électrovanne (13), intercalée entre la pompe (11) et le point de départ du tubage (7), reçoit des impulsions électriques (I) successives pour commande d'ouverture et de fermeture, qui créent des ondes de choc sur la ligne d'eau contenue dans le tubage (7), lequel transmet ces ondes de choc jusqu'au piston de frappe du corps de perforatrice (8).
Applications : travaux souterrains, exploitations minières, en particulier utilisation dans des galeries de faible hauteur.

摘要： A rotating inner member is used to drive a downhole tool housed within the hollow outer member of a dual-member drill string. The downhole tool preferably will be adapted t receive rotational energy from the inner member. In a preferred embodiment, the downhole tool is an electric generator connected to a downhole electric device. In another preferred embodiment the downhole tool is a mechanical transmission that uses the rotational energy from the inner member to drive a non-electric tool, such as a downhole hammer. This invention will increase the consistency and efficiency of downhole energy production.

摘要： A clutch assembly (16) transmits rotary motion in a percussive apparatus (10) to a drill steel. The clutch assembly (16) includes a first hub (18) having a first cylindrical surface (24) formed thereon. A second hub (20) which is substantially rotationally coupled to the drill steel, has a second cylindrical surface (26) formed thereon. The second cylindrical surface (26) is coaxial with the first cylindrical surface (24). A wrap spring (17) engages a portion of both the first cylindrical surface (24) and the second cylindrical surface (26), wherein relative rotary motion between the first hub (18) and the second hub (20) is permitted in a first direction and restricted in a second direction. The wrap spring clutch (16) transmits motion supplied from a rifle bar assembly as well as a plunger bar arrangement.
