Definitions

  • the invention relates to a compactor device attached to an excavator can be coupled, an upper part for coupling to an excavator and a lower part with an unbalance generator, between which a or more damping devices are arranged, wherein in Upper part at least one buffer device for vibration decoupling and a rotating device are provided.
  • Compressor devices use for dynamic compression an unbalance generator that drives a compactor plate.
  • the imbalance generator is usually powered by a hydraulic motor driven.
  • Known compressor devices have a lower part and an upper part, between which damping devices, such as Example rubber-metal buffer, are arranged.
  • the rubber-metal buffers are necessary to those generated by the unbalance generator To use energy for compaction. However, they also serve In addition, the vibrations up to the excavator or the excavator to reduce. This usually does not succeed completely, so at a coupled compressor device via the excavator Vibrations are transmitted to the excavator, which adversely affects affect the life of bearings, bolts and the like.
  • Compressor devices are in the prior art centered on the Dredger arm coupled. At a point compression can be a Such device can be controlled without problems. Will the However, compressor device pulled or pushed, this creates the Problem that the compressor device can not be guided.
  • Coupled compressor devices are usually on the Hydraulics of the excavator driven.
  • Excavator for use with Compressor devices come into question have only certain Options for adjusting the hydraulic quantity. In general it is the set amount of hydraulic much higher than actually for the Drive the imbalance required. As a result, that is disproportionate large hydraulic motors with a high displacement be used.
  • the excavator must be different when compacting Fulfill functions at the same time.
  • the compressor device must be driven, the superstructure must be pivoted
  • the excavator handle and excavator arm are and must be moved become. Due to these additional activities, the amount of hydraulic varies for driving the compressor device. These fluctuations cause fluctuations in unbalance speed, which adversely affect can affect the compaction.
  • Compressor devices often to different excavators with different Hydraulic services are coupled. This will cause the unbalance speed also exposed to strong fluctuations.
  • the drive of compressor devices is usually about the so called "hammer line" of the excavator.
  • the hammer line is a Form pressure of approx. 150 to 250 l / min with a working pressure of approx. 150 generated up 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 generated bar. For this reason are used for driving the imbalance Standard gear pumps used. These may be due to their design only withstand a certain back pressure. Often the Hammer line, however, combined with a shear line. In functional mode "Scissors" can mutually define the hydraulic direction become. Application examples are all attachments for an excavator, which work in two directions, eg.
  • the upper part has a Ankuppelabrough and a middle section between which the at least one buffer device, in particular, several rubber-metal buffers, is arranged.
  • the at least one buffer device in particular, several rubber-metal buffers.
  • a coupling device be provided, which is arranged off-center.
  • the Compressor device can be better coordinated and guided.
  • One Another advantage is the longer reach when compacting. Farther the compressor device can be under overpressing during compression Obstacles are introduced. This is especially true of exposed ones Cables in sewer construction advantageous.
  • the Coupling comprises a rotating device.
  • the turning device can be mechanical, in particular rotatable by 180 °, or hydraulically be formed rotatable.
  • a hydraulically rotatable trained Rotary device can be made an endless rotation.
  • the compressor device be guided by the excavator to almost any point.
  • the coupling device is at least in a section, in particular axially, variable in length educated.
  • the coupling device is telescopic.
  • the coupling device further comprises an elastic Pressure element, in particular a compression spring, preferably between two telescope sections acts.
  • the compressor device both used for static as well as for dynamic compaction become. In a floating position, d. H. with extended variable-length Ankuppel issued or relaxed compression spring can a dynamic compression take place. An additional static pressure is not exerted by the excavator on the compressor device.
  • a particularly fast connection of the compressor device to a Excavator can be done when the coupling device a hitch system includes, with which a mechanical and hydraulic Connection made with the excavator arm when coupling simultaneously becomes.
  • This measure has the advantage that hydraulic connections do not have to be coupled separately.
  • the Unbalance generator an axial piston motor or a reinforced gear motor with leak oil connection.
  • the axial piston motor or the gear motor has a low absorption volume.
  • an axial piston motor or a reinforced gear motor is used with drain connection is the Compressor device up to a back pressure of about 250 bar used. This means that the excavator when coupling a Compressor device no longer from the functional mode "scissors" on the function mode "Hammer" must be changed.
  • the compressor device can be used in both modes.
  • the control of the axial piston or the reinforced gear motor with leak oil supply amount supplied used on hydraulic fluid a flow control valve.
  • the imbalance will usually depend on the size of the compactor plate maximum approx. 70 - 150 l / min required.
  • the superfluous hydraulic fluid can be controlled by the flow control valve in front of the engine be derived. Power fluctuations are compensated by and it becomes a constant speed of the axial piston motor reached.
  • the flow control valve is adjustable. By this measure, the speed can be adjusted for the imbalance become.
  • the physical properties of the soils to be compacted are very different.
  • the speed of the unbalance therefore has one significant impact on the compaction property.
  • With a flow control valve The speed can be easily adjusted.
  • the same compressor device can easily adapt to different Excavators are coupled and operated at the same speed become.
  • the lower part of the compressor device having an exchangeable compressor plate having an exchangeable compressor plate.
  • a change system the change of Simplified compressor plates.
  • the change of Simplified compressor plates With such a system can be different Plate sizes on the compactor device easy be attached.
  • For narrow trenches can narrow plates and
  • For wide trenches wide plates can be mounted.
  • Different compressor plates can be used.
  • For example can use plates with a smooth surface through plates to be replaced by a "Schaffuß".
  • Schaffußplatten have in cross section trapezoidal blocks on which for the compression of for example loamy soils are beneficial. This means that at one Construction site no longer different compressor devices, but only still different compressor plates must be kept.
  • FIGS. 1a and 1b each show a compressor device 1, 30 in FIG Section, wherein like elements with the same reference numerals are provided.
  • the compressor device 1, 30 comprises a top part 2 and a lower part 3, wherein between the upper part 2 and the lower part of the third designed as a rubber-metal buffer damping devices 4 is provided are.
