Definitions

  • the invention relates to a milling machine that can be attached to a mobile supporting structure, in particular a construction machine, Unimog or the like, with a mounting frame detachably attached to the supporting structure with a horizontal guide running parallel to a longitudinal or transverse side of the supporting structure, along which the milling device is attached a sliding actuator can be moved back and forth like a sled relative to the structure.
  • edge milling of the road surface is required to prevent frost damage, for example. This means that the old roadway is milled to a certain width and depth in order to be able to install the new ceiling overlapping the old one.
  • the road construction vehicle described in US Pat. No. 4,262,966 is especially designed for transverse milling.
  • the milling machine is part of a device to be built onto the chassis of a motor vehicle for milling off the road surface with simultaneous suction of the debris into a container.
  • Tubular guides are located within the vehicle chassis, from which the supporting frame unit can be extended in the direction of travel of the vehicle is.
  • a guide running transversely to the direction of travel in which a threaded rod which causes the transverse feed is screwed into a corresponding opening in an assembly carrying the cutting drum.
  • This assembly has two vertical guide rods, along which an upper housing part is articulated in a height-adjustable manner.
  • the lower housing part of the assembly carrying the cutting drum can be rotated about a vertical axis with respect to this upper housing part.
  • the lower part contains the cutting drum.
  • This consists of a horizontally mounted main shaft with two side plates attached to it, between which four chisel arm shafts are arranged - evenly distributed over the circumference of the side plates.
  • Four hammer-shaped elements are in turn articulated on each chisel arm shaft, which elements can be rotated through the chisel arm shafts by 360 °, but cannot be moved.
  • An interchangeable chisel is located at the free end of each hammer-shaped element. A mutual removal of the chisels ensures that the road surface is evenly removed.
  • the problem on which the invention is based results in designing milling cutters of the type mentioned at the outset in such a way that, on the one hand, they enable construction machines, in particular those which are difficult to maneuver, and in particular tracked vehicles, to be precise, rapid and to carry out flexible road processing, especially rapid transverse milling, and on the other hand offer the possibility of milling with a base surface inclined to the ground surface, in particular "milling running to zero" to execute.
  • a subordinate object of the invention is to provide a device which enables the creation of straight edges as possible in a single operation.
  • the invention provides in a milling machine of the type described above that can be attached to a mobile supporting structure that the axis of rotation of the milling unit can be adjusted relative to the ground surface by means of an inclination control element.
  • a milling drum that is adjustable in its inclination with respect to the ground surface with a horizontal guide that is detachably attached to a supporting structure creates an arrangement that is particularly advantageous for road construction.
  • a cultivator according to the invention can be attached both to the front or rear side and 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 system 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.
  • the adjustable angle of inclination which the axis of rotation of the milling drum encloses with the floor surface, also allows milling in which the resulting base surface is inclined with respect to the floor surface.
  • a practical embodiment consists of the fact that the frame is pivoted about a preferably horizontal axis parallel to the supporting structure, and that its pivoting position is adjustable relative to the supporting structure by means of a tilt actuator.
  • 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.
  • this special design makes it particularly easy to mill "running to zero", which means that one end of the milling drum is, for example, 4 cm deep in the material to be processed, while the other end is approximately at the level of the ground surface ("on Zero expires ").
  • 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.
  • the roller and the disk each have a drive motor, in particular. Hydromotor, to couple, which give them different angular velocities according to amount and / or sign. With this special training it is possible, for example, to separate house walls in the building renovation area.
  • the mounting frame is provided with an essentially vertically extending, further guide, along which the milling cutter can be moved up and down relative to the supporting structure by a height adjustment element, expediently with the aid of a guide slide.
  • a height adjustment element expediently with the aid of a guide slide.
  • 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 application flexibility 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 control element.
  • 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 cutter with recessed guide slots which run in a circular arc with respect to the mentioned axis of rotation of the cutter.
  • the mounting elements and / or the support point of the lowering element are 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, on each of which a longitudinally displaceable bearing bush is connected to the router or its guide carriage 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 occur in the milling operation, cannot have a serious effect on the machining accuracy and operational reliability.
  • the milling drum and the grinding wheel on the common shaft are spaced immediately close to one another. This measure ensures that no material web can remain between the milled edge and the edge.

  • 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 about the approximately perpendicular to the axis of rotation 20 extending axis of rotation 21 rotatably suspended.

  • 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 with respect 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 latter causes movement of the milling cutter 4, 5 in a substantially vertical direction 29 with respect to the base 7.

  • 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.

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.
