Definitions

  • Figure 1 is -1- the drive motor, which is flanged directly to the housing with the two imbalances driven in opposite directions via ring gears -2-.
  • -3- is a shaft which is carried out in a special embodiment for driving the drilling tool and for which separate protection is requested.
  • -4- is the drive and the bearing of an impacting / milling toothed roller chisel with this type of construction, which strikes even more via an eccentric activation and is driven extremely reduced by an intermeshing inner and outer ring gear - in a manner known per se.
  • the drive shaft (for example 3) run with a 3 mm eccentric and the counterbalance imbalance with 3,000 rpm.
  • FIG 3 -13- is the drive motor lying again in the pivot point -14- with the unbalance impact system -15- arranged on one side of the pivot point.
  • a driven, snow-running cutting or slow-turning milling tool possibly additionally activated -16-, is arranged in a displacement piece -17- so that the impact force and the respective amplitude can be selected or adjusted depending on the requirements, for which purpose as well separate protection is requested; - If the distance of the striking unit from the fulcrum is equal to that of the drilling tool, the amplitude and impact force of the striking unit and the drilling tool are identical, if you reduce the distance between the drilling tool and the fulcrum, the amplitude is reduced and the impact force is increased - vice versa.
  • FIG. 4 shows a drilling unit with a hemispherical drilling head which corresponds to that of FIG. 1 in the system - and can also be variably adjusted in all directions in the field - by adjusting / adjusting the opposing imbalances (2) and / or by rotating the housing -19-.
  • the disc drilling / ablation undercutting tool in FIG. 1 is the storage / suspension for the entire unit.
  • the suspension / buffering is not shown here - it can also be installed in the pivot, for example.
  • the striking unit can of course also be variable in distance from the drilling tool and / or from the fulcrum in order to allow a cutting / rolling or other drilling tool to work with variable forces and variable amplitudes.
  • FIG. 4 shows a drilling unit with a hemispherical drilling head which corresponds to that of FIG. 1 in the system - and can also be variably adjusted in all directions in the field - by adjusting / adjusting the opposing imbalances (2) and / or by rotating the housing -19-
  • a hemispherical boring head -20- is provided, which according to the invention is additionally activated via the eccentric in the direction -21- and can be driven slowly rotating via the declared gearwheels inside - and over the stronger linear unbalance stroke in the direction -22- - the direction of advance during full hole drilling - is superimposed; Separate protection is requested for this combination, but in particular to be able to control a pilot hole with a standing rod by rotating the housing -19- with a slightly eccentric linear stroke -23-.
  • this version can of course also be used / removed in both directions -21- - preferably when used on partial cuts / jib drilling machines, especially for plunge-cutting in direction 22 and removal-21.
  • roller-shaped or hemispherical hammering / milling drilling tools can also be installed - special protection is also requested for this - in particular for use on part-cutting / cantilever machines which, with this technology, use the hardest and most abrasive rocks - but also Can remove road surfaces / coverings.
  • the pressure forces required with these systems are a fraction of those required for conventional roller drilling tools; the pressures are also incomparably lower than with conventional milling.
  • the drilling progress / removal rates are multiple - especially in hard rock or the like.
