摘要： The rotary-percussive hydraulic perforator includes a body; a shank; a striking piston configured to strike the shank and provided with a braking surface; a braking chamber configured to hydraulically brake the striking piston; a stop piston configured to apply a pushing force on the shank and provided with a bearing surface configured to abut against a stop surface provided on the body, so as to limit the stroke of displacement of the stop piston towards the shank. The rotary-percussive hydraulic perforator is configured such that the bearing surface and the stop surface are axially spaced apart by a predetermined spacing distance simultaneously when (i) the shank bears on the stop piston and is in contact with the striking piston, and (ii) the braking surface is located at an inlet edge of the braking chamber.

摘要： The invention concerns an apparatus comprising a body (1) containing a cylinder wherein is mounted sliding an impact piston (1) of a tool, the motion of the piston being controlled by a distributor (15) which, arranged coaxial to the impact piston, is mounted inside a distribution box (3). The distribution box (3) comprises a part axially overlapping the piston (1) and arranged concentric thereto, and the distribution box (3) defines with the piston a control chamber (13) which, successively put under the high (9) and the low (12) pressure of the fluid, communicates through a passage (16) arranged in the distribution box (3) with a chamber controlling (14) the movement of the distributor (15), to generate alternately low pressure and high pressure.

摘要： A muffler for a pneumatic hammer of the type in which a cylinder receives a piston or ram which is pneumatically driven into contact with an anvil, e.g. the rear end of a tool, and in which the discharge of the air is muffled to limit the noise generated by the apparatus. The air to be discharged into the atmosphere is vented into an annular space between an outer wall of a sleeve or head surrounding the cylinder and connected by an elastic suspension thereto.

摘要： A mining drill comprising a rail along which a mining drill head is slidably rectilinear, this rail being carried by a hydraulic motor pivotally connected to a rotary head at the end of an arm swingable about a pivot axis which is generally horizontal and is formed by a column or post. A first hydraulic motor is provided to rotate the post about a generally upright axis and hydraulic cylinders can be provided to swing the post about a pivot close to its pedestal. The device is designed to support the rail so that substantially parallel holes can be drilled in a subterranean structure in practically any direction, e.g. with any inclination to the axis of the main gallery, but especially parallel thereto.

摘要： To facilitate the return of a percussion tool by the action of the striking mass, namely, a double-acting piston, without damage to the machine body, the tool is held by a casing attached to the body and the tool. The latter piston defines a chamber with a confronting face of the casing, the chamber being supplied with a liquid under pressure through a check valve. The chamber is connected to a reservoir by a pressure-relief valve.

摘要： This percussion apparatus includes a striking piston, a control distributor arranged to control a reciprocating movement of the striking piston, and a control device arranged to vary the striking stroke of the striking piston. The control device comprises a plurality of control channels, a control channel connected to the control distributor, a control slide movably mounted between a plurality of control positions, and an adjusting slide mounted in a receiving housing delimited by the control slide, the control slide and the adjusting slide delimiting a first adjusting chamber connected to the control channel and a second adjusting chamber connected to a the high-pressure fluid supply circuit. The control slide is movably mounted between a first position in which the first control chamber and the second adjusting chamber are connected and a second position in which the first control chamber and the second adjusting chamber are isolated.
