Definitions

  • the invention relates to a fitted with tools roller, according to the preamble of claim 1, for mobile machines, especially for road and road construction and forestry mulcher, on the lateral surface of clamping boxes are welded along at least one helical track, all clamping boxes on the same roller are formed and the tools are clamped in the clamping boxes.
  • a roller is known from GB 2 229 354 A.
  • Mobile working machines used in road construction, forestry and landscape management must perform various tasks, such as milling of road surfaces, crushing of milled material, crushing of ballast or packing. Furthermore, the various materials to be processed, such as bitumen, concrete, rock or wood, make different and often unpredictable demands on the machine.
  • An important task is e.g. the milling of a pavement and the simultaneous breaking of the milled material in one pass for reuse for the newly formed pavement.
  • the bits are used to mill asphalt or concrete pavement, while the crusher elements are intended to prevent coarse milled material from settling between the bit holders, and by their cooperation with the crusher bar serve to break this coarse material to a desired maximum grain size.
  • the adaptability of the roller to changed or new milling and crusher tasks is limited.
  • the ratio of the number of the two tools on the roller can be changed only by the fact that the holders and / or recesses for the two types of tools remain partially bare, whereby the performance of the roller is impaired.
  • unequipped mounts enforced during milling with fine material / bitumen need to be cleaned for repopulation and wear out.
  • Another disadvantage of the known Fräsbrecherwalze is that the crusher effect is insufficient due to the interaction of the crusher elements with the crusher bar.
  • the present invention is based on the object, equipped with tools roller for mobile machines, in particular for the road and road construction to create, with the different tasks in the field of milling and / or breaking various materials can be solved.
  • the roller according to the invention it should be possible with the roller according to the invention to approach milling and / or crusher tasks with one and the same roller on a trial basis and / or to optimize performance. It should be possible to systematically change the achievable with the machine milling, lifting and crushing effect without requiring a roll change is required, and the change in the effect should be possible without affecting the performance (or the tool density on the roller). Further advantages will become apparent from the following description.
  • the tools of at least one kind of tool are integrally formed.
  • These one-piece tools are generally flat tools, which preferably have a lifting function and / or in cooperation with a breaker bar a crusher function.
  • These tools generally have a fixed arrangement on the roller, i. they are not arranged rotatable about their longitudinal axis in contrast to round shank chisels.
  • Axially symmetrical, two-part tools and non-axisymmetric, one-piece tools are preferably used in the clamping boxes.
  • the axially symmetrical two-part tools are generally round shank bits, e.g. on milling crusher rollers perform the milling work on a road surface and are rotatably supported for the purpose of uniform wear.
  • the tool is therefore not only the axisymmetric round shank bit, but also the associated changeover holder in which the round shank bit is rotatable.
  • the non-axisymmetric, one-piece tools are generally tools that perform the lifting work and the crusher work. In general, however, it can be said that the various types of tools usually fulfill several functions. In addition to their milling function, round shank bits also have a less pronounced lifting and breaking function, while the non-axisymmetric tools, in particular, e.g. Flat chisel in addition to the lifting and crushing effect also have a certain milling action.
  • one to three wedges are formed on the clamping part of the tool, are also in each clamping box one to three exception (s) for the or the wedge (e) of the clamping part is formed and the clamping part of the tool and the clamping box are held by a screw in mutual wedging engagement.
  • This mutual wedging of the tool with the clamping box the loosening of the tool in the clamping box is almost completely avoided. Even if the tool should loosen over time, this can be eliminated by tightening the screw and thereby further retracting the wedges in the wedge shots.
  • This embodiment also includes the variant in which the or the wedge (s) are integrally formed on the clamping box and the wedge mount (s) are formed in the tool.
  • the tool or the clamping box has two wedges or wedge shots.
  • two symmetrical to its center plane wedges are formed on the clamping part of the tool and contains each clamping box two cooperating with the wedges recordings.
  • the arrangement of a respective wedge connection on both sides of a stable locking between the clamping part of the tool and the clamping box is achieved.
  • one of the two wedge surfaces of each wedge connection runs parallel to the screw axis.
  • the heights h of the tools of the different types of tools are substantially the same.
  • the axially symmetric tools namely the round shank chisel
  • the non-axisymmetric tools such as the flat chisel or chisel
  • the tools of the two (and possibly further) tool types are round shank chisel and flat chisel.
  • the tools of the two or more types of tools rotatably supported round shank chisel and immovably supported flat chisel.
  • each type of tool also contributes to the work done by the other type of tool, i.
  • the flat chisels also perform milling work and the round shank chisels work in conjunction with the breaker bar also crusher work.
  • the pitch a / b of the helical track, along which the clamping boxes are arranged in the range of 0.22 to 1.
  • the slope of this track on the cylindrical roll shell is thus larger in the embodiments than in known Fräsbrecherwalzen, as for example in DE 43 24 234.0 are shown.
  • Figure 1 shows on a segment of the roller 2 four along a helical track on the roll surface 2 a welded clamping boxes 3.
  • a change holder 4 are clamped in a manner below on the hand Figures 3 to 5 will be described in more detail.
  • the left change holder 4 is set up for the rotary holder of a round shank chisel 7 and for this purpose contains a receiving bore 6, which is indicated in FIG. 3, for receiving the chisel shank.
  • the right in Figure 1 changeover holder 4 has an angular tool holder 6 with threaded hole 4 c for screwing a tool 28 with a hard metal plate 29 by means of screw 30.
  • the clamping box 3 on the left in FIG. 1 and the second clamping box 3 on the right each contain a one-piece tool 31, at the upper end of which a cemented carbide cutting edge 32 is fixed inextricably, for example by pouring or brazing.
  • the tools 31 as well as the changeover holder 4 are formed, so that the positions of the tools 31 and equipped with tools 7 and 28 changeover holder 4 are interchangeable.
  • the tool parts 31 ' also symmetrically to its center plane integrally formed wedges 10, which engage in corresponding recesses 11 in the clamping boxes 3.
  • the heights h of the tools 7; 31.32; 28,29 above the surface 2 a of the roller equal to one another.
  • the figure shows four different tools on the roller for the purpose of explanation. In practice, the roller is generally equipped with only two or three different tools.
  • FIG 2 shows four joined sections of rolls loaded with differently blended tools.
  • Each section comprises a helical turn of the track 33.
  • five clamping boxes 3 are arranged on one turn, are used in the changeover holder 4 with round shank chisels 7,16 or 30 fastened by two-edged flat chisels 28,29.
  • the pitch a / b of the helical track 33 is about 0.28.
  • Above the clamping boxes their key figures are entered, under which the coordinates of the clamping box positions are tabulated as angle and axial distance with respect to reference planes (not specified).
  • double-edged flat bits 28, 29 of substantial overall width e.g., 25-40 mm
  • the illustrated two-edged flat chisels may be at least partially replaced by single-edged flat chisels (chisel punches) having only a cutting width of e.g. 10-12 mm.
  • the quick change holder system for the round shank chisel 1 consists essentially of a welded on the roller 2 box 3, a releasably clamped in the box 3 in the manner described below change holder 4 and a clamping screw 5.
  • the change holder 4 contains a
  • the chisel 1 is held detachably in the receptacle 6 with the aid of a spring sleeve, which is not shown in FIG. 3 and is described in more detail in DE 100 44 369.9 to FIG.
  • the diameter of the chisel head 7 at its base is sufficiently large to cover the wear-prone bearing surface 8 of the chisel holder.
  • the changeover holder 4 has symmetrical, wedge-shaped projections 10 on both sides to the median plane 9, which engage in corresponding wedge-shaped recesses 11 in the wings of the box 3.
  • the change holder 4 can therefore from the front, ie in the direction of the arrow Y, are inserted into the box 3 until the wedges 10 come in the wedge-shaped recesses 11 to the plant.
  • the changeover holder 4 can be solved even with heavy contamination by light hammer blows against the back 4 a of the spline connection 10,11.
  • the change holder 4 can be wedged by light hammer blows against the front 4 b again. In this case, a possibly present in the wedge shots contamination by the transverse holes 14 are pushed away to the outside. A worn change holder 4 can therefore be easily replaced on site.
  • a tool 15 To replace a worn chisel 1 one uses a tool 15. At the back of the box 3 is located in the central region approximately at the level of the lower mouth of the receptacle 6, an abutment 3 c , on which the tool for expelling the chisel 1 as shown in FIG 3 can be supported. By light hammer blows on the tool body fitting the expeller tool 15 then the chisel 1 can be easily expelled from the receptacle 6 and replaced.
  • the box 3 is provided on both sides of the median plane 9, each with a runner 3 d . The welding of the box 3 to the roller 2 takes place along these skids 3 d .
