摘要： A retrievable core sampling assembly for latching to or relative to a rotatable tubular housing of a core sampling apparatus to allow the capture and retrieval of a core from a subterranean formation, the assembly comprising or including: a core catcher barrel for a core, the barrel being rotationally isolated from the tubular housing and cooperable with a core taking bit coupled to the rotatable tubular housing to retain a core, and a hammer for providing impact to the core taking bit along a longitudinal impact path that is or is substantially decoupled from the core catcher barrel so that when latched, rotation and impact of the core taking bit captures and passes core material from the formation to the core catcher barrel in manner that isolates a core in the core catcher barrel from rotation and impact forces.

摘要： A system and method of fabricating a percussion tool that includes one or more coatings applied onto a piston, casing, and/or flow tube. The percussion tool includes a piston positioned in sliding contact within a casing. The piston includes an inner wall and an outer wall, where the inner wall defines a passageway extending longitudinally therethrough. The outer wall is positioned in close fitting relationship with an internal surface of the casing. One or more coatings are disposed on at least one of the casing's internal surface and/or the piston's outer wall. A flow tube may be placed through the passageway such that an outer wall of the flow tube is in a close fitting relationship with the piston's inner wall. One or more coatings can be disposed on at least one of the piston's inner wall and/or the flow tube's outer wall.

摘要： A rock drilling machine equipped with an axial bearing having at least one axial piston for setting the axial position of a drill shank and for damping stress pulses returning from the rock. The axial bearing includes a module that is detachable in one piece from one installation direction. The axial bearing module includes all necessary seals, bearing surfaces, and a module frame. Supporting forces caused by the operation of the axial bearing are transmitted of support members in the module frame directly to the body of the rock drilling machine, which is a uniform piece at least at the axial bearing.

摘要： A rock drill includes a mounting frame to which a hammering apparatus and a rotating apparatus is arranged. The mounting frame is made maneuverable with respect to a feeding beam by means of slide blocks fastened to it, whereby a separate carriage is not needed between the drill and the feeding beam. Owing to the mounting frame, the hammering apparatus and/or the rotating apparatus can be replaceable modules. The invention further relates to a mounting frame which is arranged to transmit the feed and recoil forces directed to the drill to feeding means. The mounting frame comprises a section parallel to the feeding beam, to which slide blocks are fastened, and a transverse axial support thereto, to which the hammering apparatus and the rotating apparatus are mounted.

摘要： A rotary percussive hydraulic drill including:
a body,
a shank intended to be coupled to at least one drilling bar equipped with a tool, the shank including a coupling part comprising female coupling splines and male coupling splines which are angularly offset from each other with respect to an extension axis of the shank,
a striking piston slidably mounted inside the body along a striking axis and configured to strike the shank,
a rotation driving device which is configured to drive the shank in rotation about an axis of rotation substantially coincident with the striking axis, the rotation driving device comprising a coupling member disposed around the shank, the coupling member comprising male coupling splines and female coupling splines which are respectively rotatably coupled with the female and male coupling splines of the shank
