Definitions

  • the invention relates to a device for soil compaction with at least a vibrating roller, the circumferential surface of which is composed of a plurality of segments, at least of which some have a radius of curvature that is from the middle Roll radius deviates.
  • rollers with increased compaction performance developed, d. H. with high line loads and high amplitudes, which with a Line load of up to 800 N / m and an amplitude of 2 mm.
  • Such rollers have proven particularly useful in compaction of stony soils that are not sensitive to shear stress, because they are higher Bulk layers can be compacted.
  • the vibrating Roll the soil compacting device in the circumferential direction assemble a plurality of individual segments, so that in The circumferential direction alternately successively, continuously merging outward bandage convex arch sections of two different Curvatures are formed, the one curvature stronger and the other curvature is weaker than that of the one Outside outline of the cylinder circumscribing the roller.
  • rollers can also be described as flattened in segments become.
  • This document also proposes segments of this type to provide flattened rollers in pairs, namely on the front and on the rear axle of a road roller. This is intended to achieve that ensures in particular the gradeability for the road roller is because on the one hand a bandage with a segment with weak Curvature rests on the floor while the other roller with one Segment with greater curvature at the same time for the propulsion of the Road roller ensures.
  • rollers have the disadvantage that their central axis for each lying flat on two adjacent jacket sections tipping is what requires a lot of equipment.
  • the object of the present invention is therefore one as described above To further develop roller in such a way that as far as possible on its own has good synchronization.
  • a corresponding Roll several adjacent sections in the axial direction comprises circumferentially abutting segments which in Have abutting edges offset to one another in the circumferential direction.
  • rollers The advantage of these rollers is that you Rolling behavior "is significantly improved. At the same time, the compaction as well as the propulsion or the climbing ability can be achieved with just one roller.
  • the sections arranged offset in the circumferential direction have the effect of stiffening the individual segments, as a result of which an even better Transmission of the vibration forces to the soil material to be compacted can be achieved.
  • Corresponding rollers preferably have between 2-7 corresponding ones juxtaposed sections.
  • this step gear for example with a device for detecting an oscillation number of the directional transducer can be coupled. This ensures that on each floor section on which the roller is flattened with a Segment comes to a predetermined number of vibrations is applied and thus ensures a desired compression result can be.
  • stepper transmission to advance the vibrating Coupling roller with a device that has different parameters the soil compaction is determined directly and when a target value is reached then the stepper drive controls for switching on next segment.
  • the climbing ability of the rollers is further improved if the abutting edges of the flattened segments be provided with toothed ridges projecting in the radial direction, which can also be made of a harder material and so in are able to compensate for the greater wear at this point.
  • Figure 1 shows a roller for a soil compaction device in the Side view.
  • This roller has a lateral surface 1, which is in the circumferential direction the roller is composed of four segments 2. These segments 2 collide on edges 3.
  • the edges 3 describe an arc 4, whose radius of curvature 5 is the distance of the edges 3 from the roller axis 6 corresponds.
  • the midpoints 7 of the Segments 2 an arc 8
  • the radius of curvature 9 of the distance corresponds to the center points 7 of the roller axis 6.
  • the average roll radius 10 is therefore between the radius of curvature 9 of the Center points 7 described circular arc 8 and the radius of curvature 5 of the circular arc 4 described by the edges 3.
  • a roller with a cylindrical outer surface applies vibrations a soil to be compacted by it not only on normal forces but on also thrust forces, which are very undesirable depending on the soil.
  • the segments 2 shown here are flat, i.e. that they extend in the axial direction of the shaft parallel to the shaft axis and otherwise lie in a tangential plane. So that from the segment, if it lies on the soil to be compacted, only Normal forces are transmitted, but no shear forces. So that can over such a segment is also not necessary for the roller to move Forces are applied parallel to the soil horizon.
  • the stroke movement of the shaft axis 6 can be reduced on the one hand and locomotion is also ensured with only one roller, while a section with a segment just on the Soil rests on its compaction, the feed necessary for locomotion is ensured via the adjacent section by pressing an edge there onto the soil, whereby forces parallel to the soil horizon are also to be transmitted via the then inclined segments adjoining the edge.
  • FIG. 2 For this purpose, a roller is shown in FIG. 2, in which its width a total of five sections 12 and 13 are arranged side by side. This Sections exist, as can be seen from FIG. 3, on their The outer surface consists of eight flat segments 2.
  • the flat segments abut each other in the circumferential direction without to form an undercut. That is, the one shown in FIG. 3 Angle 14 in adjacent segments is always less than 180 °.
  • FIG. 4 shows a longitudinal section through a roller according to FIG. 2. It can be seen that this has a hub 15 in the middle, which over Hub plates 16 at their axial ends, which consist of several segments Shell surface of the roller carries.
  • the individual segments 12, 13 are in the axial direction of the roller Perforated sheets 17 limited, also attached to the adjacent segments are, which are offset by an angle in the circumferential direction.
  • a directional oscillator is then advantageously installed within the hub 15, after about a predetermined number of vibrations a not shown manual transmission the roller around the above half an angle is turned so that another segment, which is then placed on the adjacent section, flat on the floor is applied and subjected to vibrations for soil compaction becomes. With this indexing, the roller moves over the abutting edges further, even with rising terrain etc.
  • FIG. 6 shows a roller with a specially designed type of segments.
  • the individual segments 16 have a concave shape, ie they are curved in the direction of the shaft axis 6. Due to such a concave configuration of the segments, a kind Focusing "of the vibrational forces on deeper ground layers can be achieved.
  • the particularly strongly protruding edges 19 are used for the locomotion, and their shape makes them suitable for applying the locomotion of the roller.
  • toothed racks can be seen on these edges 20 put on, which are made of a more wear-resistant material and so protect the edges 19.
  • the toothed strips 20 each run over the width of a section.
  • a corresponding compaction roller 21 can be seen in FIG 6 installed in a corresponding compression device 22.
  • This compacting device 22 also has a further roller 23 on, which is provided with a smooth jacket 24. Since the further roller 23 with the smooth jacket 24 of the compression device 22 true to the track Compaction roller 21 is tracked with this further roller 23 a further compaction of those left by the compaction roller 21 To achieve surface structure in which this through the compaction roller 21 surface structure generated by the smooth jacket 24 is also smoothed.
  • rollers as shown in Figures 1-7, too can still be provided with sections 25 which are circular cylindrical To have shape.
  • a circular cylindrical section 25, which is in the axial direction next to or between sections 26, 27 with flattened segments is arranged enables a device to drive more quietly, as shown in Figure 8, especially when they Departure to a job site.
  • Such a roller appears with circular cylindrical sections then like the roller 23 shown in Figure 8, in which instead of Smooth jacket 24 also flattened out from individual sections Sheath assembling segments could be provided.
