Definitions

the invention relates to a method and a device for dynamic compaction of soil with at least a movable roller that vibrates performs by an adjustable in its direction Vibrating force acts on the roller, so that either horizontal thrust and / or vertical Pressure forces are exerted on the ground.
the present application is based on the task to further improve this compression system and in particular over-compaction of the soil with local Grain crushing and deformation of the road surface to exclude.
This task is regarding the procedural features solved in that the vibratory movement of the roller or a part connected to it is detected and that in the event of a disturbance of the basic roller vibration vertical part of the vibration force up to the approximate Fixing the fault is reduced.
the invention is based on the knowledge that with increasing compaction of the soil and accordingly increasing soil hardness the compaction roller to Jumping tends to not only cause the compaction roller the compression quality is also subject to high mechanical stress decreases. The driver can do this Jumping is usually inadequate physically or visually perceive and then cancel the compaction process, which is mostly too late.
the present invention for jumping and the Overdensification responsible part of the vibration movement reduce in time and compression instead increased horizontal thrust switch, where jumping is impossible is.
the invention can be used as an anti-jump lock, on the other hand, as an over-compression barrier be considered . It therefore also allows work with higher vibration amplitudes than before, because damage to the roller from hard floors are no longer possible.
the disturbances caused by jumping the basic vibration of the roll are available to the expert various possibilities. It can be the amplitude the vibration movement or a derivative thereof, in particular the acceleration. So takes, for example, the vertical portion of the acceleration if the roller loses contact with the ground.
the period of the Vibration movement can be detected because here when jumping almost doubling occurs.
Compaction process is done by a compactor with at least two parallel or aligned to the roller axis arranged, rotating in opposite directions synchronously Excitation waves, their position and / or phase position is so variable that its resulting Centrifugal force optionally horizontal thrust and / or exerts vertical pressure on the ground.
the invention Process is then implemented in such a way that the roller or a part connected to it with a motion sensor to record the vibration movement is in operative connection and that the motion sensor is connected to a control loop that the position in the event of a disturbance of the basic roller vibration and / or phase position of the excitation waves in the sense adjusted to reduce the vertical pressure forces.
the excitation waves are arranged approximately horizontally next to each other are and the adjustment between horizontal and vertical centrifugal forces by changing the phase position of the excitation waves is effected like this in itself is known.
the excitation shafts are usually above gear wheels in operative connection with each other so that for adjustment the phase position of an excitation wave is fixable Rotary bearing between it and the one assigned to it Gear can be used.
This pivot bearing suitably consists of one connected to the gear Adjustable helix, axially screwable is an adjustment axis that is axially displaceable, however is rotatably connected to the excitation shaft.
the phase position should be over 150 °, especially to almost Can be adjusted 360 °.
excitation waves to store in a rack that is one to them parallel axis swiveling and in the desired Swivel position can be determined.
FIG. 2 schematically shows the two excitation waves 5 and 6, each arranged inside the roller 1 and 3 are.
both excitation waves lie horizontally next to each other and they keep this position regardless of the roll rotation and regardless of whether vertical pressure forces, horizontal shear forces or a combination thereof should be generated. They turn in opposite directions, can but relative to the phase position of their unbalances be twisted towards each other.
the roller 1 is in a manner known per se at one Front side on ball bearings 7 and rubber elements 8 a support 9, on the other side via rubber elements 10 and the drive motor 11 suspended from a support 12.
the supports 9 and 12 each run upwards to the frame, i.e. to the structure 2a.
excitation shafts are 5 and 6 with the adjustment mechanism 18 in a housing 19 stored, which in turn can be rotated in the drum 1 stored and over the rubber elements 8 with the support 9th connected is.
the control loop for the jump limitation is in FIG. 7 shown. It consists of an accelerometer 20, for example the vertical acceleration the roller 1 detects, where it is expedient a non-rotating part of the roller or roller suspension assigned.
the measured actual values are fed to an arithmetic unit 21 which determines the periodicity, in the present case, the duration of the vertical vibration component of the roller determined and a predetermined setpoint of reverse polarity overlaid. If the specified setpoint is exceeded, an actuator 22 receives a signal and actuates in turn, the adjusting mechanism via an actuating cylinder 23 18, such that the phase difference between exciter shafts 5 and 6 is adjusted that the vertical pressure force in favor of the horizontal Thrust decreases.
FIG. 8 shows the change in the vibration behavior, if the roller increases due to increasing ground rigidity jump starts.
the vertical acceleration component over time or plotted over the angle of rotation of the excitation waves in the right picture the vertical and horizontal Acceleration components in polar coordinates.
the curve shape shown an almost exact sine curve or an arc in polar coordinates under normal compression conditions.
With increasing ground rigidity leave both curves their ideal shape and finally the in Figure 8b configurations shown.
the upper limit value for the vertical acceleration component is about 40 m / s 2 to be entered in the control loop, so that the behavior shown in FIG. 8 b can never occur.
