Definitions

  • the systems according to the invention have the advantage that their activation means that they require at least 50% less drive, pressure and propulsion - in one version with optimal balancing they even run absolutely free of vibrations - require considerably lighter machines, experience has shown that they can process any type of rock and hardness can and also work at comparatively high speeds - designed as rollers are particularly suitable for removing road surfaces - and in spherical form particularly suitable for so-called partial cut / boom machines; - Separate protection is requested for both applications - but especially for the extremely compact construction / combination according to the invention, which on the other hand also enables a particularly wide working surface.
  • the roller that rotates on the crankshaft or eccentric sleeve and has two bearings on the outside, e.g. 400 mm diameter can be driven separately - e.g. at 100 rpm - via chain, V-belt, gear wheels or the like; but also rotate without drive e.g. Discs with rollers slowly reverse to the direction of rotation of the eccentric shaft or sleeve.
  • Counterweights for balancing can be readjusted - preferably from the outside.
  • two high-speed, synchronously driven imbalances which are offset in opposite directions and run against one another in the interior of the rotating rollers / balls and which are powerful Generate linear impact, which in particular increases the speed of advance in hard rock and significantly reduces the necessary pressure forces.
  • FIG. 1 shows the removal roller -1- provided with picks or the like, which rotates only slowly due to a drive which is not shown in this figure and belongs to the prior art; -2- is a high-speed crankshaft, -3- is e.g. adjustable counterweight for balancing by loosening a clamping screw and turning it on the shaft; -4- are the external bearings on the crankshaft and in the holders; -5- are the brackets and the crankshaft is driven via -6-.
  • Figure 2 -7- is a removal tool designed as a ball - activation, drive etc take place according to Figure 1.
  • -8- is a special type of unbalance, which can generate an additional stroke in any position for eccentric activation; - separate protection is requested for this.
  • the second drive takes place on the other outside of the roller, ball or Like.
  • the drive shaft -16- which is synchronously offset by 180 ° to the unbalance -13- but driven in opposite directions in order to produce a linearly directed additional massive stroke.
  • -17- is an inner ring gear arranged on the roller or the like, which runs eccentrically on a stationary outer ring gear which is smaller in amplitude - and thus the roller -9- is set down in slow revolutions in relation to the snowing eccentric sleeve -11-.
  • Figure 4 corresponds essentially to Figure 3 - but has the advantage of a one-sided drive.
  • 2 disk and bevel gears are provided in the embodiment shown -20- and -21-.
  • the slow-running roller or the like is preferably driven again via the gear pair -22-;
  • Both high-speed imbalance shafts and the eccentric sleeve are driven on one side and / via shaft -23- and gear pairs -24- and -25-.
  • the holding arms or the like. -26- are buffered radially or linearly, suspended in a spring-loaded manner on the machine frame or the like during the oscillating work according to FIGS. 2, 3 and 4 - so that they can be moved by the size of the respective amplitudes.

Abstract

Des rouleaux, billes rotatifs ou similaires servent à compacter, forer, déblayer, fraiser des rochers ou d'autres matériaux. Les rouleaux, billes ou similaires, pourvus de pics de havage, de disques ou similaires, sont actionnés depuis l'intérieur, sont montés de manière rotative et tournent à faible vitesse. Dans différents modes de réalisation, l'actionnement se fait au moyen d'excentriques ou de manchons rapides, ou au moyen de protubérances radialement ou linéairement percutantes de préférence par une association des deux moyens. Lors du havage, les rouleaux, billes ou similaires sont entraînés à une faible vitesse de rotation.
