Definitions

  • the invention relates to a milling machine that can be attached to a mobile structure, in particular to a construction machine, a Unimog or the like. Road construction vehicles.
  • edge milling of the road surface is required to prevent frost damage, for example.
  • two work steps have so far always been necessary: wet cutting with a diamond joint cutter, removal of the remaining material web of a certain width.
  • the mechanical removal of the remaining web of material is difficult because during the road milling, the carrier vehicle of the milling machine cannot move and maneuver as precisely as would be necessary for grasping the web of material by the milling drum.
  • cross milling is constantly necessary for edge milling in road construction.
  • conventional carrier vehicles that are suitable for mounting cultivators and the self-propelled cutters, it is cumbersome to mount cross cutings for cross connections.
  • the above-mentioned vehicles are too large in length, particularly in view of the cramped construction sites, to allow milling across the direction of the lane in a train, i.e. without maneuvering forward and backward.
  • the invention is therefore based on the problem of creating crop milling cutters of the type mentioned at the outset which are equipped with constructional and in particular caterpillars which are commercially available and can only be blurred vehicles enable precise, quick and flexible road processing, especially rapid cross milling.
  • a milling cutter with the features mentioned at the outset to provide a mounting frame which is detachably attached to the supporting structure and has a horizontal guide running parallel to a longitudinal or transverse side of the supporting structure, along which the milling cutter can be moved back and forth in a sled-like manner relative to the supporting structure by means of a sliding actuator is.
  • Such a cultivator can be attached to the front or rear as well as to one of the two long sides of the carrier vehicle. If the milling machine is connected to the front or rear of the mobile support structure via its mounting frame, the horizontal guide runs parallel to one of the two sides and therefore transversely to the direction of travel or road direction. With the help of the sliding actuator, it is now possible to push the milling machine with its processing tools back and forth like a track-guided carriage during the milling process. Cumbersome turning maneuvers to bring the carrier vehicle into the transverse position are no longer necessary. The advantage is thus achieved that, in principle, relatively large support structures, which were originally not designed for milling use, can also be used for the purpose according to the invention.
  • an excavator is discarded from its bucket and provided with a tiller according to the invention. Its relatively large immobility can then be compensated for by the intended use of the slide actuator along with horizontal guidance in the mounting frame of the milling machine according to the invention, whereby of course the mobile carrier is at a standstill.
  • the actuator is expediently designed as a pneumatic or preferably hydraulic actuating cylinder.
  • This slide actuator cylinder is - for the practical realization of the inventive concept - supported at one end against the horizontal guide, and engages with its other end on the milling machine or - in the case of a slide guide - on its slide.
  • the mounting frame is pivoted about a preferably horizontal axis parallel to the supporting structure side, and that its pivoting position by means of a Tilt actuator is adjustable relative to the structure.
  • An inclination adjusting cylinder used to implement this actuator can then be expediently arranged such that it is coupled on the one hand to the supporting structure and on the other hand to the mounting frame.
  • the mounting frame is provided with an essentially vertically extending, further guide, along which the milling cutter - expediently with the aid of a guide carriage - can be moved up and down relative to the supporting structure by means of a height adjusting element is.
  • a height adjusting element When using an adjusting cylinder for the height adjustment, it is supported at one end against the supporting structure or the vertical guide and engages with the other end on the milling cutter or its guide carriage.
  • This aim also corresponds to another embodiment of the invention, according to which a depth control element is provided which acts on the milling cutter in order to be able to adjust its (processing) depth in relation to the ground level.
  • a (depth) actuating cylinder used for this is supported at one end against the mounting frame and engages at the milling machine with its other end.
  • the depth control element can be advantageously combined with the previously described height control element in that a rough depth / height adjustment is first brought about with one control element and then a desired fine adjustment is achieved with the other control element.
  • a further embodiment of the invention serves to increase the mobility and flexibility of use of the milling cutter according to the invention, according to which it is rotatably suspended on a slide connected to the horizontal guide about an axis approximately perpendicular to its axis of rotation, and that its rotational position can be adjusted by means of a transverse actuator.
  • An actuating cylinder which may be used for this purpose is attached at one end to the horizontal guide, preferably its end part, and at the other end to the milling cutter.
  • the motion control can advantageously be created in the aforementioned configuration in that the slide has a plate which projects over the supporting side and holds the milling cutter with recessed guide slots which run in a circular arc to the axis of rotation of the milling cutter and in which the mounting elements and / or the support point of the lowering element is movably received and can be displaced relative to the horizontal guide by means of the transverse adjusting element.
  • the circular-arc-shaped recesses in the holder plate are easy to produce, and the holder elements, for example, slidably received therein, can be easily realized by screw connections, the projecting screw heads with their underside facing the thread forming sliding surfaces on the plate.
  • the horizontal guide is essentially formed from two parallel, spaced-apart spars, each of which has a bearing bush which is connected to the router or its guide carriage and can be moved longitudinally is applied.
  • this horizontal guide consisting of two rails, the attachment of the milling cutter is stabilized to such an extent that the natural vibrations of the milling drum, which inevitably arise in the milling operation cannot have a serious impact on machining accuracy and operational safety.
  • the milling cutter has a milling drum and a grinding wheel which are arranged in a rotating manner on a common shaft, either the milling drum or the grinding wheel being rigid and the respective other Tool are mounted freely running on the shaft, and both are driven in different ways.
  • One concretization is to couple the roller and the disk to a drive motor, in particular a hydraulic motor, which give them different angular velocities depending on the amount and / or sign. With this special training it is possible, for example, to separate house walls in the building renovation area.
  • the wall can be cut with the milling drum with a sufficiently large diameter and, on the other hand, the plaster can be precisely ground out in one operation due to the separate running of the smaller grinding wheel.
  • Another advantage is that during the combined milling and grinding roller and disc can be driven in opposite directions of rotation and so natural vibrations of the two rotating elements cancel each other. As a result, an extraordinary smooth running is achieved overall, which promotes the machining accuracy when milling and grinding edges of the wall plaster, the road surface or the like. Above all, with this training it is possible to grind a precise, unbroken and straight edge at the same time during surface cold milling, where if there is no web between the milling drum and the grinding wheel.
  • a mounting frame 2 is pivotably articulated in a vertical plane on the support structure 1 (not shown) on a mobile pedestal.
  • the mounting frame 2 forms a connecting or coupling member for the actual milling machine 4, 5, consisting of the milling drum 4 and the grinding wheel 5 arranged parallel to it.
  • the articulation point 3 forms a pivot axis extending horizontally (into the plane of the drawing) about which the milling cutter 4, 5 together with the associated mounting frame 2 can be pivoted into a specific angular position with respect to the floor surface 7 by means of the inclination adjusting cylinder 6.
  • the tilt actuating cylinder 6 is coupled at one end to the support structure 1 via the further articulation point 8 and to the mounting frame 2 at its other end via the further articulation point 9.
  • an essentially vertical sliding frame 10, directed towards the floor surface 7, is arranged in the mounting frame 2, projecting transversely from the holding webs 11.
  • a vertical guide 12, for example formed from a tube or the like, extends between these and parallel to the displacement frame 10. This is partially surrounded by a bearing bush 13 sliding thereon, via which the milling cutter 4, 5 can be adjusted in height.
  • the bearing bush 13 has a sliding web 14 projecting towards the supporting structure 1, which is connected to the lower end of the height adjustment cylinder 15. Its upper end is expediently attached in the region of the articulation point 3, which forms the horizontal pivot axis for the mounting frame 2.
  • the horizontal guide 16 with associated, parallel bars 16a, 16b and the cooperating slide actuator cylinder 17 are indicated by dashed lines in FIG. 1 and are explained in more detail with reference to FIGS. 2 and 3.
  • a guide carriage 18 is coupled to the horizontal guide 16 and the vertical guide 12 in terms of movement, from which a mounting plate 19 projects approximately parallel to the axis of rotation 20 of the milling cutter 4, 5.
  • the router 4, 5 is on the underside of the mounting plate 19 by approximately perpendicular to the Rotati onsachse 20 extending axis of rotation 21 rotatably suspended.
  • a retaining bolt 22 inserted into the mounting plate 19 through which the axis of rotation 21 runs, a depth adjusting cylinder 23 supported against the underside of the mounting plate 19 and a guide screw 24 are indicated schematically in FIG. 1 in FIG. 1.
  • the head of the guide screw 24 rests on the top of an angle frame 25, which is attached to the top of the mounting plate 19.
  • the end of the depth setting cylinder 23 opposite the mounting plate 19 is connected to the milling cutter 4, 5 (not shown in FIG. 1), so that in addition to the height adjustment by the height adjusting cylinder 15, a further, more refined adjustment of the distance of the milling cutter 4, 5 compared to it the bottom surface 7 can be brought about.
  • FIGS. 2 and 3 According to the position shown in FIG. 1, the working sides of the milling drum 4 and the grinding wheel 5 are visible with round shank chisels 27 on the drum 4 and diamond segments 28 on the drum 5. Furthermore, the position inclined relative to the floor surface 7 can be seen, which can be brought about by actuating the inclination adjusting cylinder 6 (pivoting of the mounting frame around the articulation point 3).
  • the end face of the milling cutter 4, 5 facing the supporting structure 1 can be immersed approximately 4 cm in the material to be milled, while the opposite end face is at the same level with the floor surface.
  • the immersion depth in the material to be milled can be adjusted by the depth adjusting cylinder 23 and / or the height adjusting cylinder 15, the first and / or the second-mentioned causes a movement of the milling cutter 4, 5 in a substantially vertical direction 29 with respect to the base 7.
  • the height adjustment cylinder moves the guide carriage 18 along the vertical guide 12.
  • the milling cutter (here covered by the angular frame 25) with its mounting frame 2 is attached to the front side of a (schematically indicated) carrier vehicle 30 with the direction of travel 31.
  • the mounting frame 2 has a structure approximately similar to a parallelogram: the horizontal guide 16 formed from one or more parallel spars is fastened in further mounting webs 32 which extend perpendicularly thereto and project perpendicularly from one of the two ends of a receiving frame 33 , which runs approximately parallel to the horizontal guide 16 and serves to stabilize it.
  • the axis of rotation 21 leading through the holding bolt 22 extends perpendicular to the plane of the drawing according to FIG. 2.
  • the rotatable suspension is essentially realized by means of circular guide slots 34, which are formed by aligned recesses made in the angle frame 25 and the mounting plate 19 located underneath.
  • the radii of the circular curvatures of the guide slots 34 each intersect the axis of rotation 21 approximately in the region of the retaining bolt 22.
  • the heads of the guide screws 24 visible in FIG Guide slots slidably received; for the displacement along the marked, circular path, the transverse actuating cylinder 26, whose end facing away from the receiving frame 33 is received in one of these guide slots and, according to the example shown, can be moved back and forth along a circular arc corresponding to 90 °.
  • Fig. 3 parts corresponding to Figs. 1 and 2 are given the same reference numerals. Compared to the exemplary embodiment according to FIG. 2, this differs according to FIG. 3 in that the milling cutter with mounting frame 2 is attached to the longitudinal side of the carrier vehicle 30 with the direction of travel 31.
  • the structure 1 and the mounting frame 2 are only roughly indicated to simplify the drawing.
  • the depth adjustment of the milling grinding roller 4, 5 can be effected by means of a rotating spindle 47 during the working process.
  • the milling machine 4, 5 can run on rollers 414 which are pressed onto the spindle 47.
  • rollers 414 skids or the like can also be attached.
  • a bearing shaft 410 carries the milling grinding roller 4, 5, to which the milling roller 4 and the grinding wheel 5 are combined as a combined unit.
  • the milling drum 4 is firmly screwed onto the bearing shaft 410 and is driven by a hydraulic drive motor 44 and carries the round shank 27 as working tools.
  • the grinding wheel 5 is freely supported on the bearing shaft 410. It carries the diamond segments 28 and is shown in the drawing by means of the further hydraulic motor 43 Example driven by V-belts 38.
  • the drive of the milling drum 4 and the grinding wheel 5 are thus separated so that their speeds can be selected so that the peripheral speeds of the work tools (round shank chisel 27 and diamond segments 28) can be adapted to the prevailing operating conditions. Esp. the directions of rotation of the roller 4 and the disc 5 are opposite to each other.
  • the small distance between the roller 4 and the disc 5 is clear, whereby a complete working out of the material plane 49 is possible in one operation.
  • the edge 45 remains precisely straight during milling grinding.
  • the grain 412 embedded in the high-strength material is not thrown out during milling, but is simultaneously ground in one operation by means of the disk 5. A precise connection of the new ceiling to the edge 45 of the old covering is now possible.
  • the sectional view acc. 6 shows the method of operation by means of the milling drum 4 with a larger diameter and a smaller width, while in this case the grinding wheel 5, which is smaller in diameter, grinds out the straight edge 45 again. This happens again in one operation.
  • Working by means of the roller 4, for example with a larger diameter, is necessary for the cutting of road surfaces at the start of work in the civil engineering area and for the wall cutting in the building renovation area or the like.
