Definitions

  • the invention relates to a soil compaction device according to the preamble of patent claim 1.
  • Such a soil compaction device is e.g. B. a vibration plate, in which a vibration driven by a motor generates a substantially vertically directed vibration that acts on a compression plate.
  • a vibration plate in which a vibration driven by a motor generates a substantially vertically directed vibration that acts on a compression plate.
  • it is suitable for moving the compaction plate forwards or backwards over the soil to be compacted and for making the plate steerable.
  • Such a soil compaction device is e.g. B. from DE 198 40 453 AI known. It has an extendable undercarriage so that shorter distances can be covered on a construction site with the device without the need for a transport vehicle.
  • Vibration plates such as the AVP 2920 from AMMANN are also known, in which a chassis is provided with a swivel mechanism which can transfer wheels from a rest position into a driving position.
  • the swivel mechanism is designed to be expensive to avoid wear on the swivel bearings due to the vibrations that occur.
  • the swivel mechanism is attached to the upper mass or the drawbar in the aforementioned vibration plate.
  • the position of the wheels in the driving position lies under the compression plate in these designs. Due to the drawbar arrangement and a very large center of gravity of the entire system from the wheel axis, the driving behavior is not very satisfactory. In the case of larger compression plates in particular, high holding forces are necessary in order to prevent the plate from tilting in the direction of travel about the wheel rotation axis.
  • the installation of the undercarriage in its driving position often poses questions for the user, since usually a whole series of movements have to be carried out. This is associated with a risk of injury to the operator if the installation is incorrect.
  • the invention has for its object to provide a soil compaction device with a chassis in which the disadvantages described above are avoided.
  • a soil compacting device with a lower mass having a compacting plate, an upper mass connected to the lower mass via a spring damper device, a vibration generator acting on the compacting plate and a running gear with one or more rolling bodies rotatably arranged on a running gear axle for transporting the device are characterized in that that the chassis axis is stationary with respect to the device.
  • the stationary chassis axis with respect to the device means that the rolling elements are already in their driving position during the vibrating operation. Extending or swiveling the chassis axle is therefore not necessary for transport, and a part that is particularly susceptible to wear, namely the extending or swiveling mechanism, is eliminated, which results in lower acquisition costs, less downtime, lower maintenance costs and easier operability of the soil compaction device.
  • the center of gravity distance of the overall system from the undercarriage axis is thereby reduced. This improves the driving behavior of the device in transport operation.
  • the soil compaction device can be constructed in a particularly advantageous manner by selecting the axle position of the chassis axle for a given rolling element diameter such that in a vibrating position the compacting plate is in flat contact with the ground and the rolling elements do not touch the ground. In a transport position, however, the compaction plate does not touch the ground, but the rolling elements touch the ground and bear the weight of the device.
  • a change between vibrating and Transport position is possible by tilting the entire device about an axis that essentially corresponds to the chassis axis.
  • Another advantage results from inserting an intended imbalance on the rolling elements.
  • the effect of this is that the rolling elements have the tendency to rotate by themselves when the compression plate vibrates, so that the bearings carrying the rolling elements are not subjected to selective loads and even the use of rolling bearings is possible.
  • FIG. 1 is a perspective view of a soil compaction device according to the invention in the transport position.
  • FIG. 2 shows a rear view of the soil compaction device in the vibrating position
  • 3 shows a side view of the soil compaction device in the vibrating position
  • FIG. 4 shows a side view of the soil compaction device in the transport position.
  • FIGS. 1 to 4 essentially show the same soil compaction device according to the invention, in each case from different angles and in different operating states. Since the figures designate the same object, they are also described together.
  • the drive usually a gasoline or diesel engine, drives a vibration exciter 6 which is coupled to the compression plate 2 in such a way that the vibrations generated by the vibration exciter 6 are transmitted directly to the compression plate 2 and thus into the soil to be compacted.
  • the undercarriage 7 has an undercarriage axle 8 which is stationary with respect to the soil compaction device and around which one or more rolling elements 9 are arranged rotatably.
  • the chassis 7 is attached to the lower mass 1, in particular to the compression plate 2.
  • the center of gravity distance of the overall device from the chassis axis 8 thus decreases, which in turn improves the driving behavior of the device in transport operation.
  • the tendency of heavy compaction plates to tip around the chassis axis in the direction of travel during transport is reduced.
  • the chassis axis can consist of an actual component, but it can also be a fictitious axis of rotation which is formed by supports 8a, 8b which are attached to the compression plate 2 and which carry the rolling elements 9 (FIGS. 2 and 4).
  • the axle position of the chassis axle 8 is chosen for a given diameter of the rolling elements 9 such that in a vibrating position (FIG. 3) the compacting plate 2 is in flat contact with the ground and the rolling elements 9 do not touch the ground, however, in a transport position (FIG. 4) the compacting - The plate 2 does not touch the floor, but the rolling elements 9 touch the floor and bear the weight of the device.
  • a change between the two positions is possible by tilting the entire device about an axis that essentially corresponds to the chassis axis 8. By simply tilting the compression plate 2 in the direction of a drawbar 10, it is possible, for example, to switch from the vibrating position to the transport position.
  • axle position of the chassis axis 8 and the size of the rolling elements 9 such that a distance a between a ground contact surface of the compression plate 2 and the lowest point of the rolling elements 9 in the vibrating position and a distance b by which the rolling elements 9 in Transport position protrude before the lowest point of the compression plate 2, can be reached. If the distance b is sufficiently high, the soil compaction device can also be moved without problems even when the ground is uneven, the distance a at the same time having to be selected in such a way that it is ensured that the rolling elements 9 do not touch the ground during vibration operation.
  • the chassis axis 8 is arranged above the compression plate 2, which enables a favorable relationship between the line of action of the operator traction force on the drawbar 10, the center of gravity of the overall device and the position of the chassis axis 8, so that very good driving comfort without tilting in the direction of travel is achieved.
  • the rolling elements 9 are also subjected to high acceleration due to the arrangement of the undercarriage 7 on the lower mass 1, in particular also on the compression plate 2, it is advisable to provide the rolling elements 9 with a targeted imbalance 11 so that they vibrate develop the desire to turn itself around the chassis axis 8. This counteracts punctual wear on the rolling element bearings.
  • the use of roller bearings for the rolling elements 9 is therefore particularly suitable.
  • the embodiment shown here has a tread surface 12 for supporting the torque required for changing the positions laterally on the upper mass 4, so that the operator can, for example, load the tread surface 12 with his foot and tilt the tiller 10 backwards Driving position or transport position can reach.
  • This type of change from the vibrating to the transport position and vice versa harbors a significantly lower risk of injury compared to soil compaction devices with swiveling or extendable undercarriages and can be carried out very quickly because no conversion of the undercarriage is required.

Abstract

L'invention concerne un dispositif de compactage de sol, notamment une plaque vibrante, comportant un mécanisme de déplacement (7) fixé sur une masse inférieure (2), qui présente un axe (8) fixe par rapport au dispositif. Une position appropriée de l'axe du mécanisme de déplacement (8) permet aux corps de roulement (9) de ne pas toucher le sol, lorsqu'ils se trouvent dans une position de vibration, mais d'être toutefois en contact avec, par simple basculement de l'ensemble du dispositif autour d'un axe, correspondant approximativement à l'axe du mécanisme de déplacement (8), et par conséquent, de favoriser la mobilité. Comparativement à des dispositifs classiques de ce type, ledit dispositif présente l'avantage de ne pas nécessiter, pour le transport, de sortir ou de faire pivoter l'axe du mécanisme de déplacement ni les mécanismes requis à cet effet.
