Definitions

  • the central drill and milling tools should also be able to be advantageously assembled and disassembled in the desired number, so that there is also less maintenance work in this regard and the milling head can be configured as required with little effort and adapted to the piles to be machined, which can have a diameter of more than 2 m can.
  • the segments of the pile core and the pile casing can be removed by linearly lowering the milling head. Complex movements of a tool, which are difficult to execute and can lead to damage to the pile head, are no longer necessary. The processing of the pile head is therefore possible within a short time without causing any damage.
  • the inner ring plate is preferably connected to the underside of a shank and the outer ring plate is connected to the underside of a mounting cylinder, the shank and the mounting cylinder being aligned coaxially with the axis of rotation and connected at the top to a coupling plate on which the coupling device is arranged.
  • the mounting cylinder preferably includes at least one exit window through which the conveyed milling material can be discharged, and at least one mounting window which allows manual access to the coupling device, for example.
  • the at least one conveyor spiral or two conveyor spirals preferably rotated by 180° relative to one another, is provided with a side wall in a lower section, which is preferably selected according to the height of the pile heads to be processed.
  • the side wall ensures that the milled material in the lower section cannot escape from the spiral conveyors and from the remaining area of the pile head, which contains the Has reinforcement, can be promoted. Only after the milling material has been conveyed out of this area can it emerge laterally in an upper section of the conveying spiral, which is not provided with a side wall, and be guided out of the milling head via the at least one exit window.
  • the central drill When operating the milling head, the central drill penetrates the core of the pile first.
  • the central chisels then penetrate the pile core sequentially and in stages in pairs, so that the pile core is machined from the inside out.
  • the surface tension of the pile core is broken step by step by arranging the central chisel in a stepped manner. Instead of rupturing the surface of the pile core in one step, the surface tension is broken gradually and thus with reduced force.
  • the milling head according to the invention can therefore be operated efficiently with reduced force or reduced drive torques.
  • the central chisel and ring chisel are preferably arranged in at least two spirally running rows and are mounted on the underside of the inner ring plate and the outer ring plate, respectively.
  • the chisel height of the central chisel preferably increases, as described, linearly or non-linearly sequentially from central chisel to central chisel in the direction of the axis of rotation or in the direction of the central drill radially inwards.
  • the invention therefore combines these three essential advantages, which are normally mutually exclusive. With reduced energy consumption, material is broken down faster and more gently. It should be noted that the milling process is promoted on the one hand by the disposal of the milling material according to the invention and on the other hand by the advantageous arrangement of the central chisel and/or ring chisel.
  • the central chisels provided on the central milling machine and the ring chisels provided on the ring milling machine preferably consist of a holder that can be welded or mounted in a form-fitting manner and a chiseling element that can be inserted therein and that can be routinely replaced.
  • the holders are preferably connected to the associated holders or assembly elements of the ring plates by means of form-fitting connections, for example dovetail connections.
  • the ring chisels are preferably dimensioned somewhat larger than the central chisels. Further one of the ring bits can be connected to the inner ring plate as a clearing bit.
  • the milling head is made of durable material, especially iron and steel.
  • the tool parts that come into contact with the concrete pile are preferably made of hard metal.
  • the milling tools include receiving openings are used in the hard metal elements that are used to machine the concrete.
  • Plastic parts can be used if they have the desired strength and should give the milling head or parts of it a certain elasticity, for example.
  • the ring milling machine 12 comprises an outer ring plate 122, on the underside of which ring bits 121 are mounted in the direction of rotation or inclined thereto.
  • the upper side of the outer ring plate 122 is preferably detachably connected to the underside of a mounting cylinder 123, e.g. by means of flange elements and screws or threaded elements, the upper side of which is preferably detachably connected to the coupling plate 133, e.g. by means of flange elements and screws or threaded elements.
  • the assembly cylinder 123 has a quarter section through which the view of the central milling machine 11 is uncovered.
  • the assembly cylinder 123 has exit windows 1231 through which loosened milling material can be carried away to the outside.
  • the assembly cylinder 123 has assembly windows 1232 on the upper side, which allow access to the milling head 1, e.g. in order to release the central milling machine 11.
  • the outer ring plate 122 has an outside diameter d122o and an inside diameter d122i.
  • the inner ring plate 112 has an outer diameter d112.
  • the increase in the mounting height of the ring bit 121 is preferably in a range of 5 mm - 25 mm.
  • the increase in mounting height of the first ring bits 1211, 1212, ... is close to 5 mm and the increase in mounting height of the last ring bits ..., 12111, 12112 is close to 25 mm.
  • Figure 5a shows the complete with central chisels 111; radial vanes 118A, 118B; conveyor blades 119A, 119B; clearing tools 1119A, 1119B; and the central drill 114 tipped inner ring plate 112 of Figure 3a in spatial representation.
  • a series of central chisels 111 is provided with the associated serial numbers 1111, 1112, ..., 1108. Also shown on the right is a view over impeller blade 119B through transfer opening 1120B.
  • the underside of the inner ring plate 112 is provided with annular steps S1, S2, S3, S4, S5, which preferably correspond to the working groups m1.
  • the blade inclination angle a4 which is approximately 45° in the embodiment shown, is therefore selected in such a way that the milled material can reach the transfer opening 1020B via the conveyor blade 119B and on to the conveyor spiral 113B.
  • the conveying blade 119B has an outer wall 119S so that the conveyed milling material cannot escape to the outside.
  • the transfer surface 1125B is preferably shaped in such a way that a preferably laminar transition without obstacles results between the conveyor blade 119B at the entrance of the conveyor spiral 113B.
  • Figure 6b shows the inner ring plate 112 of FIG Figure 6a without the feed spirals 113A, 113B, the shaft 115 and the feed blade 119B.
  • a connection space with a connection surface 1127 is exposed at the lower edge of the transfer surface 1125B or on the underside of the transfer opening 1120B, in which the conveyor blade 119B is fastened. eg screwed and/or welded.
