Definitions

  • the invention relates to a milling head for wall or floor milling according to the preamble of claim 1.
  • DE-GM 200 17 850 describes a milling head that can be mounted on an excavator arm known for longitudinal or transverse cutting of floors, the one attached to it Carrier console having a control rail that extends up to substantially extends to the free end of the milling head and is arranged at a distance from it.
  • a milling head is suitable for milling soils, in particular harder soils such as concrete, asphalt, rocky floors or the like, but there are also cases in protruding areas on walls, be it somewhere in the middle or upper wall area or adjacent to the floor.
  • the Control rail can not be used for this, so that when using one of an excavator-guided milling head depending on the material to be milled would swing accordingly and dance back and forth.
  • the object of the invention is to provide a milling head according to the preamble of To create claim 1, which makes it possible in the vertical direction substantially milling with exact depth and level.
  • a flat plate is attached to the milling head, which is in extends at an acute angle and tangential to the free ends of the milling cutter and is arranged at a distance from the milling tool, the milling head with the Press the flat plate through the excavator against a wall and then on this under Milling away from any of the above areas, for example on gable walls or Foundations or the like slide.
  • the milling head can Use appropriate milling of floors, then the flat plate on the Soil pressed and along areas protruding from it with milling is moved. This results in low-noise and low-vibration milling.
  • Fig. 1 shows a first embodiment of a milling head for the wall Milling.
  • Fig. 2 shows a second embodiment of a milling head for wall or milling on the bottom.
  • the milling head shown in Fig. 1 comprises a hydraulic, for example working drive unit 1, the flexible lines, not shown is supplied.
  • the drive unit 1 carries one on each side essential horizontal axis rotating milling tool 2 (schematically by the two circles R1 and R2 are shown, whose radius difference is the maximum milling depth results) that has a large number of milling chisels (round shank chisels) on its jacket has, wherein the milling tools 2 are arranged coaxially to each other.
  • the intended milling depth and therefore no bouncing or unevenly To effect deep milling is a thick-walled, round bracket 19, the milling depth determined, provided.
  • the bracket 19 can be used to achieve corresponding milling depths be interchangeable, but instead it is conveniently on the one hand a joint 20 is articulated on the drive unit 1 and on the other hand via a Set screw 21 (or an adjusting spindle) on a tab 22 of the drive unit 1 held so that the circular arc-shaped bracket 19 in its support area its distance from the drive unit 1 is adjustable.
  • the bracket 19 advantageously has on its side facing the drive unit 1 Ribs 23 for reinforcement and for greatest milling depth also for support.
  • a plate 10 is clamped, at the end of a flat plate 24 at a predetermined acute angle, for example an angle between 45 ° to 70 °, is directed towards the milling tools 2, which over Struts 25 on the plate 10 and additionally supported on the drive unit 1 and is stiffened.
  • the face plate 24 extends tangentially to the outside free ends of the milling cutter corresponding to the circle R1 and is with its lower one End spaced from this, i.e. the flat plate 24 ends laterally over the Milling tools 2.
  • the excavator operator can the face plate 24 via the hydraulic cylinder press the excavator against the wall and then steer it under the wall slide down to the exact depth and level milling of the above areas to let.
  • the respective milling depth is set via the bracket 19.
  • a plane plate 24 'supported by struts 25' on the milling head can but can also be used for bottom milling, as shown in FIG. 2, according to the plane plate 24 'on the side opposite the plane plate 24 of the milling head 1 is to be installed.
  • the flat plate 24 ' is then against the floor pressed and runs in the milling direction the milling tool 2 by an intended Milling depth h, i.e. aligned with the bracket 19, upward with respect to the radius R1 offset before, while the flat plate 24 runs after the milling tool 2.
  • the plane plate 24 ' is expediently adjustable in height, for example on the struts 25 'attached.
  • the plane plate 24 or 24 'required in each case can be mounted on the milling head, however, both flat plates 24, 24 'can also be provided.
