Definitions

  • the invention relates to a vibrating plate according to the preamble of patent claim 1.
  • Vibration plates are known and consist, in principle, of a lower mass having a ground contact plate and an upper mass resiliently coupled to the lower mass and having a drive (for example a combustion or electric motor).
  • the drive drives a belonging to the lower mass, the ground contact plate acting on vibration exciter device.
  • a so-called single-shaft exciter or towing oscillator in which the drive rotatably drives an imbalance shaft carrying an imbalance mass.
  • the imbalance shaft tears at its rotation, the ground contact plate upwards and forwards to achieve a forward movement. Thereafter, the ground contact plate is pressed by the action of the imbalance shaft down and strikes the soil to be compacted.
  • the vibration exciter device has two or three mechanically or positively coupled unbalanced shafts.
  • two imbalance shafts each carrying an imbalance mass
  • the phase angle of the imbalance shafts to each other can be adjusted mechanically via a link device or a differential gear.
  • Bowden cables or spindles are known as drives for the adjustment hydraulic cylinders.
  • the imbalance mass is divided on one of the imbalance shafts into two or more part-imbalance masses which are adjustable relative to one another. If the partial imbalance masses on the imbalance shaft are adjusted asymmetrically to each other, a yaw moment can be reversed generate the vertical axis of the vibrator, whereby the vibrating plate can be steered. In a symmetrical adjustment, in particular, if fixed unbalance masses are fixedly mounted on the imbalance shaft in question and other partial imbalance masses are relatively movable, the resulting imbalance effect can be adjusted, which allows adjustment of the resulting imbalance forces.
  • the imbalance shafts are arranged parallel to each other in known vibration exciter devices. With modern vibration plates, it is thus possible to achieve a forward and a reverse drive and to turn the vibrating plate on the spot or to go around a curve. In some applications, however, the user desires a transverse movement of the vibrating plate, e.g. B. to drive behind lateral projections. During soil compaction of laterally inclined surfaces, the vibrating plate often drifts down obliquely, requiring the operator to tilt the vibrating plate for compensation. However, the bottom is compacted at the top and bottom edge only by a corner of the ground contact plate, resulting in insufficient compaction results.
  • the vibrating plate could perform a transverse movement.
  • a corresponding force effect in the transverse direction would have to be achieved by the vibration exciter, which is possible only by obliquely or angularly arranged unbalanced shafts.
  • the angular arrangement of unbalanced shafts in known vibration exciter devices and their mechanical coupling to the common drive would require a considerable amount of gearbox and accordingly high costs and weight.
  • a vibrating plate with an upper mass and a bottom contact plate having lower mass known.
  • the ground contact plate is acted upon by a vibration exciter device with two vibration exciters.
  • Each of the vibration exciters consists of two parallel, mutually positively rotatably coupled and counter-rotating shafts, each carrying an imbalance and are arranged mutually adjustable in their relative phase position.
  • the invention has for its object to provide a vibrating plate, in which the mechanical complexity for the drive of the unbalanced shafts in the vibration exciter device can be reduced.
  • a vibration plate according to the invention has an upper mass comprising a drive, a lower mass having at least one ground contact plate and a vibration exciter device acting on the ground contact plate.
  • the vibration exciter device has at least two individual exciters, each comprising at least one imbalance shaft carrying an imbalance mass.
  • the individual exciters are according to the invention individually controllable with respect to the speed and / or the phase angle of the respective unbalanced shaft.
  • small units in the form of individual exciters are provided according to the invention, which in the simplest case have only a single unbalance shaft.
  • the rotational speed and the phase angle of this imbalance shaft can be controlled individually, ie independently of the rotational speed or the phase position of further unbalanced shafts.
  • the entire vibration exciter device has at least two of these individually controllable individual exciter.
  • the phase position of the imbalance shaft relates to their relative position in relation to the one or more, with it cooperating imbalance waves. If one of the imbalance shafts defined as a reference system, the other unbalanced shaft or the other unbalanced shafts can either rotate with the same phase or be rotated by a certain phase angle.
  • the phase angle of each of the unbalanced shafts should be defined in terms of a unified frame of reference.
  • each of the individual exciters on the respective imbalance shaft rotationally driving hydraulic motor or electric motor and the position of the imbalance shaft in at least one position detecting position sensor.
  • Each of the unbalance shafts are individually driven by their associated hydraulic motor (electric motor), while on the other hand via the position sensor, the actual position of the imbalance shaft is regularly or constantly monitored.
  • the position sensor should detect the position of the imbalance shaft at least in one position, ie during one revolution of the imbalance shaft once, from which the rotational speed of the imbalance shaft can be determined and also intermediate positions can be interpolated.
  • the position sensor can also be designed such that it detects the rotational position of the imbalance shaft and thus their speed permanently. The exact detection of the rotational position is important in order to derive the phase position of the unbalance shaft.
  • the hydraulic motor associated with an actuator in particular a hydraulic valve
  • the individual exciter comprises a controller, for evaluating a signal from the position sensor and for driving the actuator, such that the controller for the unbalance shaft predetermined target speed and / or Target phase position is achieved.
  • each individual exciter has its own control loop, in which the imbalance shaft forms the controlled system and the position sensor forms the measuring element.
  • the position of the imbalance shaft and thus its actual phase position and actual speed is determined with the help of the position sensor and fed as a measured value to the controller.
  • the evaluation of the signal from the position sensor also take place only in the controller itself to z. B. to determine the IstDrehunter.
  • the controller controls the actuator, in particular the hydraulic valve, so that the assigned hydraulic motor drives the imbalance shaft in the desired manner.
  • a central control is provided for coordinating the controller of the individual exciter and for prescribing an individual desired speed and / or desired phase position for each controller of the individual exciter, such that a desired by an operator and / or predetermined by a work or driving program behavior of the ground contact plate is achieved.
  • the central controller e.g. a process computer, thus has the task of forming the link between the operator and the individual exciters of the vibration exciter device.
  • the operator gives the central control a driving intention for the vibration plate, z. B. Forward, reverse, rotation, lateral or cornering.
  • corresponding driving programs are assigned to this user request, from which specifications for the individual desired rotational speeds and in particular desired phase positions of the unbalanced shafts in the individual pathogens are derived.
  • These setpoints are fed individually to the regulators of the individual exciters, whereby the regulators of the individual exciters ensure a corresponding behavior of the respective unbalanced shafts.
  • a "total responsible" central controller is provided instead of the controller of the individual exciter and the parent central control.
  • the central controller is used to evaluate the signals from the individual positioners of the individual exciters and to individually control the actuators of the individual exciter, such that the desired by the operator and / or predetermined by a driving program behavior of the ground contact plate is achieved.
  • the central controller provides centralized control.
  • the central controller centrally detects the behavior of each imbalance shaft and takes the necessary measures to ensure that the imbalance shaft reaches the required rotational behavior. Again, the user request or a predetermined driving program is relevant, after which z. B. a forward or reverse travel of the ground contact plate is required.
  • the unbalance shafts of the individual exciters are driven at the same speed.
  • a behavior of the interacting individual exciters can be achieved, which corresponds to the behavior of known, purely mechanically operating, in particular based on a form-locking coupling of the imbalance waves involved vibration exciters.
  • the imbalance shaft is driven by at least one of the individual exciters at a different rotational speed than the imbalance shafts of the remaining individual exciters.
  • this other speed an odd multiple, z. B. a triple or a fivefold of the rotational speed of the imbalance waves of the remaining individual exciters amount.
  • a special vibration behavior of the vibration exciter device can be achieved, which would be practically impossible or only with considerable effort realized in purely mechanical vibration exciters with gearboxes. A only temporary deviation of the speed would be almost impossible with purely mechanical vibration exciters, because it would require a manual transmission.
  • the different rotational speed of at least one of the imbalance shafts may allow for certain applications particularly hard impacts are introduced into the soil.
  • At least one of the individual exciters can be controlled in such a way that the imbalance shaft assigned to it specifically reaches a non-uniform rotational speed.
  • the assigned controller becomes Although always try to keep the speed of the unbalance shaft at the specified value. Due to the high speed, however, it can be assumed that the controller will not be able to compensate for the speed fluctuations for the energy exchange. Rather, it will be sufficient for the normal case to set the mean phase angle and speed of the imbalance shaft to the desired setpoint.
  • the controller has the task of imparting a non-uniform rotational speed in a targeted manner, regardless of the virtually unavoidable speed fluctuation in practice. It could be appropriate that the imbalance shaft specifically reaches different rotational speeds during a revolution to z. B. to allow a longer ground contact of the ground contact plate, so that the impact energy can be effectively introduced into the ground.
  • a second vibration exciter device acting on the ground contact plate is provided, with at least two unbalanced shafts which are positively coupled to one another and driven in opposite directions. At least one of the imbalance shafts of the second vibration exciter device is associated with a position sensor for determining the phase position of this imbalance shaft. A signal from this position sensor is fed to the central controller or to the central controller in order to coordinate the speed and / or the phase position of the imbalance shafts of the second vibration exciter device with the individual exciters.
  • the second vibrator may serve to generate vibrational forces that are used only for forward or reverse travel while achieving force effects for steering or traveling the vibrating plate through the vibrator with the single exciter according to the present invention.
  • the only mechanically operating second vibration exciter device is used exclusively to generate vertical compression forces, while the forces for locomotion and steering of the vibrating plate are achieved by the individual exciters of the vibration exciter device according to the invention.
  • the central controller or the central controller coordinate the behavior of the second vibration exciter device with the individual exciters of the vibration exciter device according to the invention in order to achieve the desired behavior of the ground contact plate.
  • the position sensor has a rotation angle detection device. This makes it possible to precisely detect the position and thus also the speed of an imbalance shaft at any time.

  • the unbalance shafts of the individual exciters are arranged on the ground contact plate such that force vectors generated by them act in different planes.
  • the imbalance masses arranged thereon each generate a centrifugal force vector which rotates in a plane which is perpendicular to the axis of rotation of the imbalance shaft. If the axes of rotation of the imbalance shafts are arranged differently directed on the ground contact plate, accordingly, the force vectors of the imbalance masses act in different planes.
  • force effects can be different Directions are generated, which cause a corresponding movement behavior of the ground contact plate.

B. recognition that the vibration plate is used in the predominant case in forward and reverse drive, while rotations and turns and skew more represent the exception or require less force. Accordingly, the individual exciters, which serve for the forward and reverse drive should have unbalanced shafts with greater imbalance mass than the individual exciters, which are only intended to effect a curved or inclined drive.
