    摘要: Ce bras-support (1) permet de maintenir la glissière (2) parallèle à elle-même. Un pivot de base (4), tournant autour d'un axe vertical (OZ), est commandé par un premier vérin (7). Un bras (10,15), articulé au pivot de base (4) autour d'un axe horizontal (W), est commandé par un second vérin (12). Un bloc-support (18) est monté tournant à l'extrémité du bras, sa rotation étant commandée par un moteur (20). Sur ce bloc est articulé un berceau (23) supportant la glissière (2) et commandé par un troisième vérin (25). Le moteur (20) et le troisième vérin (25) sont asservis aux paramètres de position résultant des mouvements commandés par les deux premiers vérins (7) et (12), par l'intermédiaire de calculateurs, de manière à maintenir automatiquement la glissière (2) parallèle à elle-même. L'invention s'applique aux appareils de foration pour l'avancement des galeries de mines et le creusement de tunnels.

    摘要: A drill boom arrangement comprises a boom proper that is universally pivotably carried by a boom support. The boom carries a feed beam for a rock drill. The boom is swingable on the support by means of two hydraulic cylinders forming a tripod and the feed beam is swingable on the boom by means of two hydraulic cylinders forming another tripod. One of the boom swinging cylinders (17) is coupled in series with one of the feed beam swinging cylinders (28) and these two cylinders are actuated by means of a common direction control valve (58). The boom swinging cylinder (17) can be short-circuited so that the feed beam can be swung upon actuation of the direction control valve (58) while the boom is arrested. The other boom swinging cylinder (16) is coupled in series with the other feed beam swinging cylinder (29) to a common direction control valve (57) in the same way. A joy-stick (59) is coupled to the two direction control valves (57,58) through pilot valves and pilot lines (64-67).

    摘要: In a drill boom arrangement, a feed beam for a rock drill Is turnable by means of a hydraulic turning device (34) about an axis (45) that is normally parallel with the axis of drilling during drifting. When not actuated, the turning device (34) is at least partially relieved of torque by means of a friction coupling (52) which is coupled in parallel with the turning device and is normally engaged. The coupling is automatically released when the turning device is actuated. A slip-coupling (67) is coupled in parallel with the first coupling (52) and in series with the turning device in order to avoid overloading of the turning device which is hydraulically self-braking.

    摘要: A drilling and winning installation for mining has a support frame and several working tools adjustably mounted thereon in the desired position and linked to bearing, carrying and/or driving means. The working tools form together with the bearing, carrying and/or driving means a module which is able to carry out and/or drive the associated group of working tools all together and/or to carry and/or drive separately the individual tools forming a group of working tools, by means of the carrying and/or driving mechanism. Each given group of working tools provided for implementing a given technological process is designed as a unit able of carrying out the corresponding working steps.

    摘要: An apparatus for forming a slit in a base rock and a concrete surface, constructed simply, capable of efficiently making a deep slit having a predetermined width and a smooth inner surface, and suppressing an increase, which would otherwise be caused by the replacing of bits, in the slit-making cost. This apparatus has a plate type bit (17) fixed to the front end of a laterally swingable plate (13), a drill bit (11) fixed to the front end of a rod (9a and/or 9b) extending rotatably and slidably along at least one side of this plate, and strikers (5 and/or 12a, 12b) for striking the plate and rod simultaneously or separately. The rod is provided at its front end portion with a stabilizer for stabilizing the direction of sliding. The plate type bit consists of a plurality of detachable bit blocks.

    摘要: A drilling machine includes a coupling means (19) for removably coupling the drilling machine (1) to the bucket of an excavator with the aid of gripping arms (20, 21). Between the drilling machine and coupling means there is a rubber member (9) taking up misalignment stresses and a gas spring (11, 12) taking up shock and compression stresses arising in conjunction with drilling.

    摘要: A portable light weight robot arm assembly simulating shoulder, elbow, and wrist movements of a human arm, plus extensions of the upper arm and forearm, accurately positions and holds a power tool (H) for performing driving, drilling, chipping, lifting and the like operations at a work-site. The assembly is self contained having a base (11) easily and quickly mounted on a conventional truck (T) or on the ground (R) at the work-site, a carriage (12) shiftable longitudinally and transversely on the base, an upright pedestal (13) tiltable in all planes relative to the base, an extensible boom or upper arm (14) rotatably and swingably mounted on the pedestal, and an extensible power tool suspension arm or forearm (17) pivoted to the upper arm. Hydraulic jacks control the lowering, raising, and extension of the boom, the tilting of the pedestal, the positioning of the carriage, the extension and positioning of the forearm, and the position of the tool. An hydraulic motor controls the rotation of the pedestal and a hydraulic motor can also operate a winch (19) on the boom. The jacks and motor are selectively activated from a portable station, such as a hand held switch unit, permitting freedom of movement of the operator to best observe the work. The upper arm is swung and tiltable about its shoulder (67-70) on the pedestal and extended or retracted to position its outer end or elbow (16). The forearm is suspended on the elbow to position the tool, extended to load the tool, and the tool is held by the wrist end (P) of the forearm in its desired position on the work.
