Definitions

  • the invention relates to a motor-driven soil compaction device, in particular a trench roller, with at least one above the ground moving and this compacting role.
  • Such soil compacting devices are in numerous embodiments in use all over the world.
  • a roll or drum width of 610 mm (24 ) up to 650 mm required.
  • trench rollers are also used outside of trenches used for surface compaction.
  • trench rollers with 610 mm roll width tend to tip over when compacting the surface. This applies before especially with remote controlled use.
  • the invention is the The task is based on the area of application and the safety against tipping Soil compactors with narrow rollers without increasing cumbersome to have to replace the bandages.
  • the soil compacting devices according to the invention by a cost-effective and particularly important in the construction site area Award structure.
  • the mounting ring itself not only weighs significantly less than the roles to be completely replaced so far, he can also be much easier than this on the soil compactor attach or detach from it.
  • the invention Trench roller is therefore universal for a wide variety Suitable for use.
  • mounting rings also saves weight and volume when transporting the soil compactor.
  • the receiving device can consist of one or consist of several screws that are inserted through the mounting ring and screwed to the roller.
  • the attachment device has at least one Centering surface, in particular a conical surface, for centering the Has mounting ring. This greatly facilitates the cultivation, because you just put the mounting ring on these centering surfaces can, so that it is in the correct position and for Attach only twisted and / or screwed on.
  • the mounting ring preferably has the same outer diameter as the role. However, for special applications it can also make sense that the mounting ring has a larger or smaller diameter or that its diameter in the direction away from the roll, if necessary conical, increasing or decreasing. This can be the case with, for example profiling floor surfaces may be useful, or even if one multi-stage or variable, the already existing degree of compaction soil-compatible compaction is desired. Depending on the roll will decrease more or less how high the compression is into the subsoil so that at the beginning of compaction a larger one and towards the end a smaller footprint of the roll on the Soil acts. The surface force that occurs increases accordingly during the work process.
  • the positive connection can by projections on the outer ring and / or Role can be achieved in recesses of the role and / or the outer ring protrude into it. There should be protrusions on the role are attached, not axially over the effective roller width for compression protrude so that you can reach the boundary walls can condense. This is also from a security perspective a satisfactory solution.
  • the projections and depressions can be aligned axially, so that the mounting ring only has to be plugged on and screwed on.
  • a particularly stable connection between mounting ring and roller results but when the positive engagement by such projections on the mounting ring and / or the role is achieved when rotated into corresponding Undercuts of the role and / or the mounting ring intervention.
  • the mounting ring has radial play and either are radial on the mounting ring, but cannot be moved in the circumferential direction Elements arranged by screws against or in Recesses of the outer cylinder of the roller are pressed. Or the mounting ring has elastic segments that are screwed together are pulled outwards and thus cause radial clamping. In both cases, the screws can attack radially from the outside, if you sink them between the tunnels accordingly.
  • the extension ring has a width of 100, 200 or 400 mm.
  • attachment rings For a larger overall width, several attachment rings can also be used be axially joined together. To do this, at least the inner ones Attachment rings a receiving device for receiving another Coaxial mounting ring to be arranged on the face for further increase the compaction width.
  • the mounting ring can be attached using the mounting device institution corresponding to the role. So it expediently carries fasteners for its assembly on the roller and / or a centering ring on its side facing the roller Face. This centering ring can also be easily attached to the hub arrange, especially if they are not in the center of the mounting ring sits, but somewhat along the ring and roller axis is placed on the role.
  • the mounting ring consists of a cylindrical one Ring without hub and spokes, which only on the outer circumference the role is connected.
  • Figure 1 you can see one of a motor-driven, not shown Compactor attached roller 1. It is flying stored by flanged to the motor via a journal 2 becomes. On its outer circumference, the role bears numerous teeth 3 arranged in rows, which when compacting into the subsurface intervention.
  • the roller 1 is a receiving device for one Has mounting ring 5.
  • this recording device is composed of several elements. These are all on the opposite of the flying bearing 2 End face of the roller 1 arranged.
  • the first element of the cradle is a centering cone 4a on which the mounting ring 5 is postponed. Centering surfaces of the cone 4a lie on corresponding ones Counter surfaces of a centering ring 6 of the mounting ring 5 on.
  • the axis of the cone 4a is the roller axis A and its diameter is about 1/3 of the in the illustrated embodiment Roll diameter.
  • the centering cone 4a is attached to the bearing journal 2 by means of screws 2a mounted, with the screw heads fully countersunk in the centering cone are so that it has a flat, radial contact surface for the front Counter surface of the hub 10 of the mounting ring 5 forms.
  • the second elements of the receiving device form fastening elements in the form of three screws 4b with corresponding counter threads, which are expediently arranged in the cone 4a.
  • the mounting ring 5 With the screws 4b, the mounting ring 5 is attached to the roller 1 and so pressed against the roller that in particular on the centering surfaces of the cone 4a results in a frictional connection.
  • Centering ring 6 gives a positive connection, which is a shift of mounting ring 5 and roller 1 against each other perpendicular to the axis A prevented.
  • the third element of the receiving device is formed by depressions 4c, which are arranged on the end face of the roller 1 and in the projections 7 of the mounting ring 5 engage. Because of this positive locking Roller 1 and mounting ring 5 connected to one another in a rotationally fixed manner. To the occurring The depressions and are to keep leverage low Radially positioned projections as far out as possible, here even on Outer cylinder of roller 1 and mounting ring 5.
  • the outer periphery of the mounting ring 5 is advantageously designed as the outer circumference of the roll 1. In this example, therefore also arranged on the mounting ring 5 teeth 8. They are on the outer edge of the mounting ring 5 lying teeth beveled towards this edge.
  • Figure 2 shows the outer end face of the mounting ring 5.
  • the arrangement of the staggered teeth 8 can be seen particularly well.
  • the three screws 4b of the holding device can also be seen and three radially extending handles 9 on the outside of the Mounting rings.
  • the second embodiment shown in Figure 3 differs is essentially different from the first Cradle. As in the first embodiment also points here the roller 21 on a cone or cylinder 24a by one Connecting ring 26 of the mounting ring 25 is enclosed.
  • the second element of the receiving device is here from undercuts behind projections 24b on the front outer circumference of the roller 21 are formed and against the projections 30 of the outer ring 25 are clamped.
  • the outer ring 25 is used for fastening in this exemplary embodiment put on the cone 24a and then twisted about the axis A, that the projections 30 of the outer ring 25 behind the lugs 24b Roll 21 arrive. Then a central screw 31 is tightened, that on the axis A in a thread through the mounting ring 25th runs through and on the end face of the truncated cone 24a of the roller 21 ends. As a result, the mounting ring 25 is in the direction of the roller 21 clamped away against this by the corresponding surfaces the projections 30 and lugs 24b are pressed against each other.
  • braced surfaces of the projections 30 and lugs 24b are appropriately profiled in the circumferential direction or by terminal Stops limited in the circumferential direction to by positive locking to achieve a non-rotatable connection.
  • the mounting ring 25 is through an inner ring 32 on the inside of the outer cylinder of the roller 21 guided.
  • the roller 41 has on the side facing away from the drive Outside cylinder on the inside of an area that acts as a centering sleeve 44a serves.
  • this centering surface acts as a guide for one from the mounting ring 45 into the outer cylinder of the roller 41 protruding inner ring 52.
  • the other are in the area or near the centering sleeve 44a in the outer cylinder of the roller 41 radial bores 44c provided.
  • Screws 44b are inserted through these and screwed with tabs 46.
  • the tabs 46 are with the mounting ring 45 shed and extend coming from this approximately a few centimeters along the centering sleeve 44a on the inside. By tightening the screws 44b, the tabs 46 become tight pressed against the centering sleeve 44a on the outside and thus mounting ring 45 and Roller 41 clamped together radially.
  • the roller 41 are to increase mobility the tabs 46 axial slots 47 in the outer cylinder of the mounting ring 45 arranged.
  • the slots 47 extend approximately over half the width of the mounting ring 45 and limit the tabs 46 laterally.
  • the tabs 46 are on their side facing away from the roller 41 integrally connected to the mounting ring 45.
  • FIG. 6 shows the arrangement of several, in the exemplary embodiment three, over the circumference distributable tabs 46 on the mounting ring 45th to recognize.
  • connection can also by means of clamping sleeves which act on inhibitors and shearing.
