Definitions

  • the invention relates to a tamping unit according to the features cited in the preamble of claim 1 and to a method for submerging a track, the known features of which are cited in the preamble of claim 5.
  • EP 1 653 003 A2 is a Stopfaggregat known, wherein the stuffing of a track stuffing pick are moved in pairs to each other. This additional movement for ballast compaction is carried out with the aid of a hydraulically actuated auxiliary cylinder. The addition movement is hydraulically superimposed on a vibratory movement in order to achieve easier penetration into the ballast and improved compaction.
  • the object of the present invention is now to provide a Stopfaggregates and a method of the type mentioned, with a reduced energy consumption for the vibration superposition in the Beistellantrieben is possible.
  • Fig. 1 a side view of a tamping machine with a tamping unit
  • Fig. 2 an enlarged side view of Beistellantriebe tamping unit
  • Fig. 3 a schematic cross section through a Beistellantrieb.
  • Tamping machine 1 shown in a simplified manner has a machine frame 4 which can be moved by rail carriages 2 on a track 3. Between the two rail bogies 2 a height adjustable by a drive 5 Stopfaggregat 6 for Unterstopfen thresholds 7 is arranged.
  • tamping unit 6 has in a Beistellterrorism 8 in pairs about a pivot axis 9 to each other movable, at a lower end 10 with stuffing toppers 11 connected tamping 12 on. These are at an upper end 13 each with a hydraulic Beistellantrieb 14 which are formed both for carrying out the Beistell Gay 8 and one of these superimposed vibration. Both stuffing lever 12 and the Beistellantriebe 14 are mounted on a height adjustable by the drive 5 relative to an aggregate frame 15 carrier 16.
  • a first pressure chamber 20 for generating the Beistell canyon 8 is arranged.
  • a second pressure chamber 21 is provided for one of the Beistell Gay 8 opposing opening movement piston rod side.
  • a third pressure chamber 22 provided for generating vibration is formed by a cavity 23 arranged in the piston rod 18. This is limited piston side by a fixed to a cylinder bottom 24 of the hydraulic cylinder 19 second piston rod 25. Both piston rods 18, 25 are arranged coaxially to a cylinder axis 26 of the hydraulic cylinder 19.
  • the three pressure chambers 20, 21, 22 are each associated with hydraulic lines 27, wherein the connected to the first pressure chamber 20 hydraulic line 27 is connected to a designed as a bladder accumulator energy storage 28.
  • a piston surface 29 the second piston rod 25 and a piston rod-side piston surface 30 of the Beistellkolbens 17 have the same area.
  • each of the first pressure chamber 20 of each Beistellantriebes 14 both stuffing lever 12 with respect to a lower portion about the pivot axis 9 are pivoted to each other by applying the stuffing tamp 11 are provided in the Beistelldoch 8 to each other.
  • the opposing opening movement is achieved by applying the second pressure chamber 21.
  • the Beistell- and opening movement of the tamping pickle 11 is superimposed in each case a composite of two vibration amplitudes, preferably sinusoidal vibration, wherein in the direction of the Beistellieri 8 (s. Fig. 3 ) acting first oscillation amplitude is generated by a pressure pulse in the third pressure chamber 22.
  • the second oscillation amplitude acting in the opposite direction is formed by a pressure pulse in the second pressure chamber 21.
  • the second vibration pulse causes fluid displacement from the first pressure chamber 20.
  • the energy generated in this way is in Energy storage 28 buffered and returned to the activation of the first vibration pulse back into the first pressure chamber 20.
