Definitions

  • the invention relates to a compressor device according to the preamble of claim 1.
  • Compressor devices use an unbalance generator for dynamic compression that drives a compactor plate.
  • the unbalance generator is in the Usually driven by a hydraulic motor.
  • Known compressor devices have a lower part and a upper part, between which damping devices, such as rubber-metal buffers, are arranged.
  • the rubber-metal buffers are necessary to use the energy generated by the unbalance generator for compaction.
  • they also serve to reduce the vibrations up to the excavator or the excavator. This usually does not succeed completely, so that vibrations are transmitted to the excavator at a coupled compressor device via the excavator, which have a negative effect on the life of bearings, bolts and the like.
  • Compressor devices are coupled centrally in the prior art to the excavator. With a point compression, such a device can be controlled without problems. However, if the compactor device is pulled or pushed, the problem arises that the compactor device can not be guided.
  • Coupled compressor devices are usually driven by the hydraulics of the excavator.
  • Excavators that are suitable for use with compressor devices have only certain options for adjusting the amount of hydraulic. In general, the set hydraulic amount is much higher than actually required for driving the imbalance. As a result, disproportionately large hydraulic motors having a high displacement are used.
  • the excavator must perform different functions simultaneously during compaction. In particular, the compressor device must be driven, the superstructure must be swiveled and the excavator handle and excavator arm must be moved. Due to these additional activities, the
  • the drive of compressor devices is usually via the so-called "hammer line" of the excavator.
  • a pre-pressure of approx. 150 to 250 l / min is generated with a working pressure of approx. 150 to 250 bar.
  • the return line of this hammer line is fed directly to the hydraulic tank, which has a back pressure of max. 15 bar generated.
  • standard gear pumps are used to drive the imbalance. Due to their design, they can only withstand a certain backpressure. Often, however, the hammer line is combined with a scissors line. In the "shear" function mode, the hydraulic direction can be mutually defined.
  • Application examples are all attachments for an excavator that work in two directions, eg.
  • Object of the present invention is therefore to develop a compressor device for an excavator such that the above-mentioned disadvantages are avoided.
  • the axial piston motor or the gear motor generally has a small displacement. If instead of a standard gear hydraulic motor, an axial piston motor or a reinforced gear motor with leakage oil connection is used, the compressor device is used up to a back pressure of about 250 bar. This means that the excavator no longer needs to be switched from the "scissors" to the "hammer” mode when coupling a compressor unit.
  • the Compressor device can be used in both modes of operation.
  • a change system can be provided which simplifies the replacement of the compressor plates.
  • different plate sizes can be easily attached to the compactor device.
  • narrow trenches narrow plates can be mounted and for wide trenches wide plates can be mounted.
  • different compressor plates can be used.
  • slabs with a smooth surface can be replaced by slabs with a "sheep's foot”.
  • Schaffußplatten have in cross-section trapezoidal blocks, which are for the compaction of, for example loamy soils of advantage. This means that at a construction site no longer different compressor devices, but only different compressor plates must be maintained.
  • the first development provides for a storage-gentle additional buffering, in addition to the damping devices which are arranged between the upper part and the lower part or connect upper part and lower part with each other.
  • the upper part has a Ankuppelabrough and a central portion, between which the at least one buffer means, in particular a plurality of rubber-metal buffers, is arranged.
  • the at least one buffer means in particular a plurality of rubber-metal buffers.
  • a coupling device may be provided, which is arranged off-center. This measure creates a caster, similar to a shopping cart.
  • the compressor device can be better coordinated and guided. Another advantage is the longer reach when compacting.
  • the compactor device can be introduced during compression under overhanging obstacles. This is particularly advantageous in exposed lines in sewer construction.
  • the coupling device comprises a rotating device.
  • the rotating device can be designed mechanically, in particular rotatable by 180 °, or hydraulically rotatable.
  • a hydraulically rotatable rotary device an endless rotation can take place.
  • the compressor device can be guided by the excavator to virtually any point.
  • the coupling device is formed at least in one section, in particular axially, variable in length.
  • the coupling device is telescopic.
  • the coupling device further comprises an elastic pressure element, in particular a compression spring, which preferably acts between two telescopic sections.
  • the compressor device be used both for static and for dynamic compression. In a floating position, ie with extended variable-length coupling device or relaxed compression spring, a dynamic compression can take place. Additional static pressure is not exerted by the excavator arm on the compactor device. However, when the excavator arm is moved down, the elastic pressure member is compressed, and the coupling device is shortened.
  • a particularly fast connection of the compressor device to an excavator arm can take place if the coupling device comprises a coupling system, with which a mechanical and hydraulic connection to the excavator arm during coupling is produced simultaneously.
  • This measure has the advantage that hydraulic connections do not have to be coupled separately.
  • a flow control valve is used to control the amount of hydraulic fluid supplied to the axial piston motor or the reinforced gear motor with leakage oil connection.
  • the superfluous hydraulic fluid can be discharged by the flow control valve controlled in front of the engine. Power fluctuations are compensated, and it is achieved a constant speed of the axial piston motor.
  • the flow control valve is adjustable. By this measure, the speed for the imbalance can be adjusted.
  • the physical properties of the soils to be compacted are very different.
  • the speed of the unbalance therefore has a considerable influence on the compaction property.
  • the speed can be easily adjusted.
  • the same compressor device can be easily coupled to different excavators and operated at the same speed.
  • Fig. 1a and 1b each show a compressor device 1, 30 in section, wherein like elements are provided with the same reference numerals.
  • the compressor device 1, 30 comprises an upper part 2 and a lower part 3, wherein between the upper part 2 and the lower part 3 designed as a rubber-metal buffer damping means 4 are provided.
  • an unbalance generator 5 is arranged, which sits on a plate 6, to which a removable system 7 is mounted on an exchangeable compressor plate 8.
  • the unbalance generator 5 comprises an axial piston motor 9 or a geared motor, the hydraulic fluid controlled via an adjustable flow control valve 10 is supplied.
  • the upper part 2 of the compressor device 1 is divided into an Ankuppelabites 11 and a central portion 12.
  • the Ankuppelabites 11 and the central portion 12 are coupled via buffer means 13 which are formed as a rubber-metal buffer. Vibrations generated by the unbalance generator 5 are not or only slightly transmitted to the Ankuppelabites 11 by this measure.
  • the coupling section 11 comprises a coupling system 14, with which a mechanical and hydraulic connection with an excavator arm can be made simultaneously.
  • the coupling section 11 also has a turning device 15, so that the compressor plate 8 can be rotated relative to the coupling system 14.
  • a suspension 31 is provided adjacent to the rotating device 15, which is connected via the buffer means 13 with one or more connecting parts 32.
  • the connecting parts 32 have the buffer device 13 at their upper end and the damping devices 4 at their lower end. This two-stage vibration isolation protects the excavator against vibrations.
  • the buffer means 13 are arranged outside the rotator 15.
  • FIG. 2a a side view of the compressor device 1 is shown.
  • an excavator arm 17 is shown, which is connected to the coupling system 14.
  • the Fig. 1 is a sectional view taken along the line II of Fig. 2a , The section line II also represents the center line through the compactor device 1.
  • the coupling device comprising the coupling system 14, the rotator 15 and the buffer devices 13 is arranged off-center. This means that the compressor device 1 can be pushed with its left half in the drawing under overhanging obstacles and can also compress below.
  • the compressor plate 8 is in the Fig. 2a formed with a smooth bottom.
  • FIG. 2b an alternative compressor plate 18 is shown, which has trapezoidal projections 19 on its underside in cross-section and is therefore particularly suitable for compacting loamy soils.
  • the in the Fig. 2b shown compressor plate 18 can against the compressor plate 8 of Fig. 2a be replaced due to the change system.
  • a compactor device 20 In the Fig. 3 an alternative embodiment of a compactor device 20 is shown.
  • an excavator arm 17 is also connected to the compressor device 20 via the hitching system 14.
  • the coupling device 21 has a first telescopic section 22 and a second telescopic section 23, which are telescopic to each other.
  • the coupling device is designed variable in length.
  • an elastic pressure device 24 which is designed as a compression spring, is provided.
  • the compression spring endeavors to push apart the telescopic parts 22, 23. If the compactor device 20 is not or only slightly acted upon by the excavator arm 17 with a force from above, the compacting device 20 acts essentially by its own weight on the soil to be compacted with a compaction force. This results in a dynamic compression. If the pressure element 24 is completely compressed, a static force is additionally exerted on the compressor device 20, resulting in a static compression.
