Definitions

  • the invention relates to a soil compacting device, in particular a vibrating plate or vibrating plate.
  • Such soil compacting devices or vibration plates are known and typically have an upper mass and a lower mass, which are usually connected to one another by rubber buffers serving as vibration decoupling devices.
  • a drive in the form of an internal combustion engine is provided on the upper mass.
  • a drawbar with a guide bracket can be attached to the upper mass, with the aid of which the operator controls the vibration plate.
  • An unbalance exciter is provided on the lower mass, which is used to generate vibrations which are introduced into the soil to be compacted via a soil contact plate also provided on the lower mass.
  • the power of the drive motor is transmitted to the unbalance exciter on the unbalance mass with the help of a belt drive.
  • a centrifugal clutch can be flanged to the internal combustion engine serving as the drive motor so that the unbalance exciter is still decoupled from the engine at low engine speeds.
  • the imbalance exciter itself often has two counter-rotating imbalance shafts which are arranged parallel to one another and each carry eccentrically arranged weights (imbalance masses) in order to be able to achieve the desired vibrations when the imbalance shafts rotate.
  • the direction of a resulting force vector can be changed.
  • the vibrating plate can be reversed, so that the vibrating plate can be moved forwards and backwards.
  • a standing vibration can also be achieved.
  • the belt drive is heavily loaded. This is due in particular to the fact that the relative position of the two belt pulleys on the upper mass and on the lower mass changes constantly due to the strong vibrations. In particular, the distance between the pulleys and their parallelism can fluctuate, which increases the load on the drive belt. In addition, the stretching of the belt during operation can cause slippage, which leads to fluctuations in the rotational speed of the unbalance exciter. The increased wear on the drive belt also increases the maintenance effort.
  • the bearing and gear wheels of such an unbalance exciter are usually lubricated with oil.
  • oil When operating the unbalance exciter, it is not only the unbalance shafts that have to be set in rotation.
  • drive energy is also required to overcome frictional losses, which are primarily caused by the imbalance masses that circulate the oil provided for lubrication in the imbalance exciter.
  • the invention is based on the object of specifying an improved soil compacting device in which the disadvantages present in the prior art can be avoided.
  • a soil compacting device is specified, with an upper mass, with a lower mass movable relative to the upper mass, with a soil contact plate for soil compaction, with a vibration decoupling device acting between the upper mass and the lower mass and with at least one unbalance exciter belonging to the lower mass for loading the soil contact plate with a Imbalance force.
  • An electric motor for driving the unbalance exciter is provided on the lower mass, the electric motor being integrated into the unbalance exciter.
  • Such a soil compacting device can in particular be a vibration plate or vibrating plate with which soil can be effectively compacted or stones can be shaken into a soil.
  • the imbalance force generated by the unbalance exciter can in particular be generated as an oscillating, directed force vector.
  • the unbalance exciter can have two unbalance shafts which are arranged parallel to one another and are coupled to rotate in opposite directions and which each carry an unbalanced mass.
  • the coupling of the two unbalance shafts can, for example, take place with the aid of a pair of gears carried by the unbalance shafts.
  • the imbalance shafts rotating in opposite directions generate a resulting force vector, the alignment of which is determined depending on the relative rotational position of the imbalance masses or eccentrics to one another.
  • the oscillating force vector changes amount and sign or direction with the rotation of the unbalance waves and thus causes a force that, depending on the oscillation phase, is directed upwards and the ground contact plate slightly lifts off the ground or - after rotation by 180 ° - is directed downwards and over the soil contact plate can be introduced into the soil to be compacted.
  • One of the unbalanced shafts can be designed as a drive unbalanced shaft and have an area which forms part of the electric motor in such a way that the drive unbalanced shaft is also the motor shaft of the electric motor. In this way, the electric motor can be integrated particularly efficiently into the unbalance exciter.
  • the drive unbalance shaft can in this respect also be referred to as the first unbalance shaft of the two unbalance shafts of the unbalance exciter. It can particularly advantageously be designed in one piece, so that it has areas that carry the unbalanced mass or eccentric, and areas that are part of the electric motor.
  • the further unbalance wave of the unbalance exciter is also referred to below as the second unbalance wave.
  • the unbalance exciter it is also possible for the unbalance exciter to have further unbalanced shafts (third unbalanced shaft, fourth unbalanced shaft, etc.).
  • a phase adjustment device can be provided between the two unbalanced shafts for adjusting the phase position of the two unbalanced shafts with respect to one another.
  • the alignment of the resulting force vector can be set.
  • the phase adjustment device can in particular be integrated into the rotary coupling of the two unbalanced shafts with one another and constructed in a manner known per se.
  • it can have an adjusting sleeve that can be rotated by axially adjusting a shift pin.
  • two intermeshing gearwheels can be provided between the two unbalance shafts, whereby the rotational position of one of the gearwheels can be changed relative to the unbalance shaft carrying this gearwheel by the adjusting sleeve assigned to this gearwheel, to effect the phase adjustment.
  • phase adjustment device is from the prior art, for example from the publications mentioned above DE 24 09 417 A and the DE 30 43 719 A1 , is known and therefore does not need to be explained in more detail at this point.
  • phase adjustment device With the aid of the phase adjustment device, it is thus possible to change the alignment of the resulting force vector and, for example, to reverse the direction (reversal).
  • the electric motor in the unbalance exciter can have a rotor which is arranged on the drive unbalance shaft. Accordingly, the drive unbalanced shaft is also the motor shaft of the electric motor in this case. The rotor is carried by the drive unbalance shaft.
  • the electric motor can have a stator which at least partially encloses the rotor arranged on the drive unbalance shaft.
  • the stator can be arranged directly in the housing of the unbalance exciter and carried by the unbalance exciter housing.
  • Electric motors such as synchronous machines, asynchronous machines or BLDC motors, are suitable as electric motors.
  • the drive unbalanced shaft can carry two unbalanced masses axially spaced apart from one another, the electric motor being arranged axially between the two unbalanced masses.
  • the rotor in particular can be arranged axially between the two unbalanced masses.
  • the axially spaced apart unbalanced masses can be arranged at the end faces of the drive unbalanced shaft. In this way, a very compact construction of the unbalanced shaft can be achieved. In addition, by arranging the two unbalanced masses at the two front ends, it can be achieved that the installation space in between is completely available for the electric motor, with stator and rotor.
  • the rotor of the electric motor it is possible for the rotor of the electric motor to rotate in a plane or an axial height that corresponds approximately to a plane of rotation or axial height in which the unbalanced mass of the other unbalanced shaft rotates.
  • the rotor, on the one hand, and this unbalanced mass, on the other hand, then consequently rotate against one another at the same height.
  • a wheel device can be provided on the lower mass for transporting the soil compacting device as required.
  • the pair of wheels can be attached to the lower mass, in particular to the ground contact plate.
  • the wheels can be detached from the ground during operation and, so to speak, float above the ground. By tilting the soil compacting device, the wheels can be brought into contact with the soil in order to displace the soil compacting device with the aid of the wheel device.
  • Such a wheel device is, for example, from DE 102 26 920 B4 famous.
  • An energy store can be provided on the upper mass to supply the electric motor with electrical energy.
  • the energy store can in particular be an electric battery.
  • the battery can either be permanently installed or exchangeable. Accordingly, it is possible to charge the battery either directly in the device, for example with the help of an appropriate power supply unit, or outside of it in a charging station to be provided accordingly or via a power supply unit.
  • the battery can be exchanged, it is advantageous if the battery can be easily exchanged, for example with the aid of a plug connection.
  • a converter device can be provided on the upper mass for converting an electrical current provided by the energy store into a current suitable for the electric motor.
  • the electric motor To achieve vibrations and vibration frequencies that are advantageous for soil compaction, it is necessary for the electric motor to reach a corresponding speed. To achieve this speed, it is advantageous if the motor, which is designed, for example, as an asynchronous machine, receives a power supply with a corresponding frequency, which, however, differs from the frequency of the public network (50 Hz). Accordingly, the converter is provided to provide a current with a higher frequency.
  • the voltage can also be adapted to a level suitable for the motor.
  • the converter device can have a housing on which a plug connection for plugging in the energy store is provided. Accordingly, it is easily possible to plug the energy store into the plug connection or - after use - to pull it off the plug connection. It is also possible that a corresponding holder or support is provided on the housing of the converter device so that the energy store can be reliably mounted on the housing of the converter device.
  • the unbalance exciter specified in this way can accordingly have a very compact design.
  • it has the electric motor with the drive unbalanced shaft as the first unbalanced shaft, as well as the second unbalanced shaft, into which the phase adjustment device can be integrated.
  • the unbalance exciter forms an integral unit with the electric motor and does not require any external drive.
  • the drive motor known in the prior art is thus replaced by an electric motor that sits directly on one of the unbalanced shafts.
  • the unbalanced masses on the second unbalanced shaft are taken along via a gear with an interposed phase adjustment device. Is on the upper mass or optionally also an intermediate mass between the upper mass and the lower mass the battery is intended as an energy storage device.
  • a corresponding cable can be provided to transmit the electrical current.
  • the fact that no internal combustion engine is required for the drive means that noise and exhaust emissions can be reduced or eliminated. This opens up additional areas of application, for example in closed rooms, tunnels and underground garages.
  • the structure according to the invention allows the number of components that are necessary for the drive to be reduced, for example coupling, V-belt, belt pulley, seals and protective housing for the drive belt.
  • the running behavior of the unbalance exciter can be stabilized because the direct connection of the electric motor eliminates speed fluctuations due to a belt drive.
  • Fig. 1 Fig. 10 shows an example of a vibrating plate serving as a soil compacting device.
  • the vibration plate has an upper mass 1 and a lower mass 2 that is movable relative to the upper mass 1.

  • the battery 5 and the converter 6 are enclosed by a protective frame 7.
  • the battery 5 is exchangeable and can be replaced with another battery if necessary.

  • the electric motor 27 By arranging the electric motor 27 directly on the first unbalance shaft, which thereby fulfills the function of the drive unbalance shaft 21, the electric motor 27 is directly and completely integrated into the unbalance exciter 10. It is therefore not necessary to drive the unbalance exciter 10 from the outside, as is known from the prior art.
  • the unbalance exciter 10 forms an integral unit with the electric motor 27 and does not require any further external drive.
