Continuously rotating hammer drill

Die kontinuierlich angetriebene Schlagbohrmaschine hat ein Gehäuse, in dem drehbar und axial gleitend verschiebbar ein Bohrerschaft gelagert ist, der auf die Bohrstange schlagend einwirkt. Im Gehäuse befindet sich eine Schlagvorrichtung für den axialen Antrieb und ein motorisch angetriebenes Getriebe für den Drehantrieb des Bohrerschaftes. Der Bohrerschaft hat eine Verzahnung, in welche ein angetriebenes Zahnrad eingreift und die in bezug auf dieses Zahnrad axial verschiebbar ist, so daß die Berührungsflächen der Zahnflanken aufeinander abrollen und stetig wechseln. Die Zahnkränze können dadurch gekühlt und gut geschmiert werden. The continuously driven hammer drill has a housing in which a drill shaft is rotatably and axially slidably mounted, which impacts the drill rod. In the housing there is an impact device for the axial drive and a motor-driven gear for the rotary drive of the drill shaft. The drill shank has a toothing in which a driven gear engages and which is axially displaceable with respect to this gear so that the contact surfaces of the tooth flanks roll off one another and change continuously. The ring gears can thus be cooled and well lubricated.

ROTO-PERCUTANT HYDRAULIC DRILLING APPARATUS

Un piston frappeur est monté coulissant à l'intérieur d'un cylindre qui délimite une première chambre annulaire reliée à un clapet antiretour monté coulissant à l'intérieur d'une chambre reliée à un accumulateur à membrane, à laquelle aboutit un conduit d'arrivée de fluide hydraulique, et une seconde chambre annulaire reliée à une valve de commande. Cette valve, pilotée par les mouvements du piston, met ladite seconde chambre en communication alternativement avec la haute pression et le conduit de retour. Le clapet antiretour, réalisé sous la forme d'un manchon soumis à la poussée d'un ressort, présente selon l'invention un ajutage latéral permettant le passage direct du fluide vers le conduit de retour, tandis qu'un moteur de rotation est intercalé sur le conduit d'arrivée. On obtient ainsi le fonctionnement de la rotation seule, pour un débit inférieur à un certain seuil, et le fonctionnement rotopercutant, au-dessus de ce seuil. A striking piston is slidably mounted inside a cylinder which delimits a first annular chamber connected to a non-return valve slidably mounted inside a chamber connected to a membrane accumulator, to which an inlet duct ends. hydraulic fluid, and a second annular chamber connected to a control valve. This valve, controlled by the movements of the piston, puts said second chamber in communication alternately with the high pressure and the return duct. The non-return valve, produced in the form of a sleeve subjected to the pressure of a spring, has according to the invention a lateral nozzle allowing the direct passage of the fluid towards the return duct, while a rotation motor is inserted. on the arrival duct. The operation of rotation alone is thus obtained, for a flow rate below a certain threshold, and the rotary percussion operation, above this threshold.

Hydraulically operated rock drill - has cutting edge raised after each axial travel and part rotated to prevent jamming in cracks in rock (SW 13.3.78)

The rock drill is hydraulically operated and has its cutting edge (12) fixed directly (11) onto the operating spindle (9) passing through the drill body (5). The operating fluid enters at the top, through a rotary motor (2). The outlet fluid then passes (3) into a chamber and up axial slots (7) to drive the spindle down. This hydraulic fluid is exhaust (8) from the machine whilst a further portion is conducted (4) to the underside (6) of the operating piston. The difference in pressures raises the drill and the combined effect of lifting the tool between blows and part rotating it prevents jamming in cracks in the rock.

ROCK DRILLING PROCESS WITH INVERSIONS OF THE DIRECTION OF ROTATION OF THE DRILL

Procédé de forage de roches au moyen d'un foret frappant la roche et tournant autour de son axe longitudinal, dans lequel on inverse répétitivement le sens de rotation du foret Selon l'invention, on inverse répétitivement le sens de rotation du foret 3 après que ce dernier a accompli au moins un tour dans un même sens. Une soupape 6 commande le moteur 4 qui fait tourner le foret dans l'un ou l'autre sens. Les connexions de commande 10 et 11 de la soupape sont reliées à un centre de commande 7 qui envoie tour à tour un signal de commande aux connexions 10 et 11 pour inverser le sens de rotation. Method of drilling rocks by means of a drill bit striking the rock and rotating around its longitudinal axis, in which the direction of rotation of the drill is repeatedly reversed According to the invention, the direction of rotation of the drill 3 is repeatedly reversed after the latter has completed at least one turn in the same direction. A valve 6 controls the motor 4 which turns the drill bit in either direction. The valve control connections 10 and 11 are connected to a control center 7 which in turn sends a control signal to connections 10 and 11 to reverse the direction of rotation.

Portable impact rock drill - has unidirection clutch between drive and housing to allow manual freeing of jams

The rock drill has a housing containing an impact mechanism with a tool holder rotatable by this. A unidirectional clutch is placed so that one part is connected to the stationary housing and the other to the impact mechanism drive. When the tool jams, it can be manually rotated in the direction opposite to the drive direction by rotating the drill housing in order to free the tool. The arrangement makes it possible to drill even where reinforcement bars or cavities in the drilled material occur, without having to extract the bit and starting a new hole. Upon restarting, the mechanism imparts a blow to the tool which should free it.

La tige de mandrin présente une denture 8 qui est en prise directe avec une denture 9 rotative par rapport à ladite tige et entraînant celle-ci en rotation, la denture de la tige de mandrin étant déplaçable axialement par rapport à la denture d'entraînement 9. Les surfaces de contact des dents sont ainsi constamment changées et entraînées en rotation, et les dents ne sont mises en îoeuvre que refroidies et lubrifiées. La denture d'entraînement peut être une roue dentée 6, 7 ou une couronne dentée. (CF DESSIN DANS BOPI) The percussion and continuous rotation drill comprises a body 1, a mandrel shank 2 rotatably mounted and sliding axially in the body in order to transmit impacts to the bit, a striking mechanism 3 arranged in the body in order to transmit impacts axial to the mandrel rod, and a rotary device 4 intended to drive said rod in rotation about its axis. The mandrel rod has a set of teeth 8 which is in direct engagement with a rotating toothing 9 with respect to said rod and driving the latter in rotation, the toothing of the mandrel rod being axially displaceable relative to the drive teeth 9 The contact surfaces of the teeth are thus constantly changed and rotated, and the teeth are only operated when cooled and lubricated. The drive teeth can be a toothed wheel 6, 7 or a toothed ring. (CF DRAWING IN BOPI)

Improvements in rotary driven coal cutting or the like machines

337,553. Butterworth, L., and Hayden, Ltd., J. E. Oct. 5, 1929. Percussive channelling-drills.-A rotary-percussive coal-cutting machine has the drill-carrying member rotated by an aligned non-reciprocating shaft, the member having projections which impinge against, or rebound from, stationary members so the drill is free from much axial constraint during its forward and backward movements. A carriage 4, pivoted to a block 2 and adjustable by worm gearing 6, slidably carries a two-part cylinder 7 with legs 9 connected to the frame 10 of a motor or turbine 11; within the cylinder is a piston-member 17 slidably engaging the flattened &c. end of an extension 22 of the motor &c. shaft so as to be constantly rotated thereby. The member 17 has diametrically-opposed cam members 32 which at intervals during the rotation of the member 17 contact with balls 38 so as to impart loose blows to the tool 20. The balls 38 rest against seats.35 held by screws 36 and nuts in recesses in segmental thickenings 33 in the cylinder. A feed screw 13 is provided for adjusting the cylinder and a lubricant cup 39 is provided, holes 41 in the piston-member permitting passage of lubricant. The motor may be fixed to the carriage 4 and drive through gearing adapted to maintain the drive throughout in spite of the feeding of the drill. The number of cams and balls may be varied, and the balls may be relatively angularly displaced.
