Definitions

  • the present invention relates to a plate compactor with an unbalance transmission, which has two waves each having an imbalance.
  • Corresponding unbalance transmissions are known from very many different plate compressors, which are also referred to as "vibrator” known, for example from the DE 10 2005 029 433 A1 , of the DE 30 32 494 and the DE 43 43 865
  • the known plate compactor are usually equipped with its own drive motor and driven by the drive motor unbalance shafts. Due to the strong vibrations that such plate compactor transferred to the ground, this is to be compacted, for example, to serve as a foundation for a new road surface or other structure, to avoid that the soil later under the burden of the corresponding structure or the applied load yields and the building in question is damaged.
  • especially retroactively occurring bumps apply avoid, which can be caused by the weight of the road, but especially by the weight of trucks that drive on a corresponding road, over time, if the ground under the road surface is not sufficient and not uniformly compacted.
  • vibrating rollers are also known which roll on the ground and, in addition to the rollers rolling on the ground, also have internal imbalance shafts which cause the entire vehicle to vibrate.
  • Plate compressors are usually moved by hand, as they lose due to their vibrations in each case briefly ground contact or reduce greatly and can be moved slowly in this way by pushing or pushing in a horizontal direction.
  • a disadvantage is, however, that such movements are sometimes very uneven and that such forward movement, inter alia, is dependent on a more or less slight slope of the soil, so that it is difficult to compact a larger floor area as evenly as possible with a conventional plate compactor , In addition, such a compaction process is relatively time consuming.
  • the compaction of the existing soil serves to reduce the void content of the soil and causes an increase in the carrying capacity while reducing the deformation sensitivity.
  • a load is introduced via unbalanced shafts, which are rotated by a circular motion.
  • the drive for this is done via internal combustion engines, "hydraulic motors or electric motors".
  • the optimal compaction in gravelly-rolling soil material would be a large balancing force with high frequency (speed) at a small amplitude. According to the state of the art, there is no compaction device that combines all three properties at high installation heights.
  • the present invention has the object to provide a plate compactor, which can bring about a uniform and rapid soil compaction, which also reduces the impact on the environment outside the soil area to be compacted.
  • the plate compactor is designed as an attachment for the cultivation, for example, excavators, wheel loaders, tractors, Unimogs, compactors and the like, and that the two waves have opposite direction of rotation and, apart from the sign, in phase rotate, the opposite rotating waves in the vertical direction rectified and perform in the horizontal direction opposite movements.
  • a plurality of unbalanced transmission each having two counter-rotating unbalance shafts, provided on a base plate, wherein each two Rotate waves of different imbalance in phase in the same direction, while, as already mentioned, the two shafts one and the same imbalance gear in terms of absolute value in phase, but rotate in the opposite direction. It is preferred if at least four imbalance shafts are arranged on a common base plate.
  • the larger number of unbalanced shafts has the advantage that, as provided according to an embodiment, the unbalanced shafts each may have only a relatively small imbalance, on the other hand rotate at high speed, so that the forces or accelerations generated by the unbalanced shafts nevertheless with the Impact of unbalanced shafts are comparable, which have a significantly larger imbalance (greater mass and / or greater distance of the center of mass).
  • the speed is more than 2000 revolutions per minute (rpm), preferably more than 3000 rpm and in particular more than 3500 rpm. In a plate compactor already produced this speed is about 3600 rpm (corresponding to 60 Hz). Because of this fast speed and because of the relatively small imbalance (small distance of the center of gravity from the axis of the unbalanced shafts), the vibration amplitudes are relatively low, but still the vertical acceleration forces very high. Specifically, such an imbalance shaft is designed so that the centrifugal force generated by a single shaft at 36000 rpm (60 Hz) corresponds to about 3 tons (3000 kp or about 30000 N).
  • the unbalanced shafts are each formed identically, in particular each have the same moment of inertia and the same imbalance (ie equal mass and equal distance of the center of gravity from the axis of rotation).
  • the waves are coupled in a phase-locked by a corresponding gear train.
  • the imbalance shafts can be coupled to each other via a toothed gearing. Furthermore, according to one embodiment, it is provided that all shafts, in particular if more than two imbalance shafts are provided, have parallel axes of rotation lying in a common horizontal plane.
  • rollers or imbalance shafts are driven by an oil engine.
  • at least two of the unbalanced shafts should be driven by an oil motor, but optionally at least four or all imbalance shafts of the plate compactor may be driven by an oil engine.
  • the oil motors of different imbalance shafts can be supplied for example in parallel or in series by a common hydraulic oil source.
  • the second unbalance transmission 3 ' is connected in series with a second oil motor 8' by the oil flow of the oil line 7 in such a way that both transmissions 3, 3 'synchronize themselves ( FIG. 2 ).
  • the hydraulic energy is only needed to turn the unbalanced shafts upwards. Since the individual unbalanced shafts 4, 5, 4 ', 5' generate a small centrifugal force or have relatively small masses and center of gravity eccentricities, they permit much higher rotational speeds (frequencies) at a smaller amplitude than conventional imbalance shafts. All shafts 4, 5, 4 ', 5' on the plate compactor 1 together generate vertically-directed vibrations at high frequency and low amplitude, which nevertheless high, are generated periodically and only in the vertical direction adding centrifugal forces. Specifically, the unbalanced shafts are designed so that they generate in a preferred embodiment at a speed of 3600 rpm a centrifugal force of about 3 t (about 30 000 N).
  • One or more plate compactors is connected via a movable or elastic suspension 11 with a carrier device such as wheel loader, tractor, excavator, roller and is pulled or pushed by this ( FIG. 3 ).
  • the plate compactor 1 therefore do not require its own drive.
  • Several individual plate compactors 1 can be joined together with the indicated unbalance gears ( Fig. 3 ) to achieve a large area performance at high heights.
  • several compression cycles and an additional compaction device can be saved.
  • the enormous vibrations in the environment which are known when operating with conventional Verdichtungsgeraten with great balancing power (large mass and / or focal eccentricity) at low frequency and high amplitude, are significantly reduced.
