Definitions

  • the invention relates to a tamping unit for tamping sleepers on a track, comprising a tamping unit with opposing tamping tools mounted on a height-adjustable tool carrier, which can be set in motion via drives and can be ordered in relation to one another, with each tamping tool having a pivoting lever rotatable about an auxiliary axis and an inner as well as a outer tamping tool holder and wherein each tamping tool holder is laterally pivotable with respect to the pivot lever.
  • tracks with a ballast bed are regularly processed using a tamping machine.
  • the tamping machine drives on the track and lifts the track grid, which is made up of sleepers and rails, to a target level using a lifting/aligning unit.
  • the new track layout is fixed by tamping the sleepers with a tamping unit.
  • the tamping unit includes tamping tools with tamping picks, which during a tamping process are subjected to vibrations and dip into the ballast bed and are placed next to one another.
  • the ballast is compacted below the respective sleeper.
  • Two tamping units are assigned to each rail of the track, each tamping a sleeper on either side of the rail.
  • Each tamping unit includes two opposing tamping tools.
  • Two tamping picks are usually arranged side by side on each tamping tool. Specifically, an inner tamping pick plunging in next to the rail and an outer tamping pick plunging in at a greater distance from the rail are provided.
  • both tamping picks immersed side by side in the gravel, there is a wide effective range. If there are obstacles on the track and particularly in the area of a switch, there is often too little space for the simultaneous immersion of the two tamping picks arranged next to one another.
  • a tamping unit with so-called swing tines In this case, laterally pivotable tamping pick holders are arranged on the respective tamping tool.
  • the outer tamping tool can first be swung up separately if there is only space between the rails, sleepers and track installations to insert a tamping tool. If there is no possibility of immersion at all on one side of the sleeper, then the inner tamping tool is swung up as well. The tamping unit can then only be lowered with the tamping picks of the tamping tool opposite.
  • a disadvantage of the known arrangement of swivel picks is the space required for the respective swivel mechanism including swivel drives.
  • the invention is based on the object of specifying a tamping unit of the type mentioned at the outset with a compact design.
  • the outer tamping tine holder can be pivoted about a first pivot axis and that the inner tamping tine holder can be pivoted about a second pivot axis that is offset relative to the first pivot axis. This eliminates the need to arrange elements next to one another for pivoting the tamping tool holders.
  • the staggered arrangement enables optimized use of the available installation space. The result is a compact tamping unit that has small external dimensions, particularly in the longitudinal direction of the track.
  • a first contact element is advantageously arranged on an outer side of the inner tamping tool holder, with a second contact element being arranged on an inner side of the outer tamping tool holder and with the two contact elements being pivoted downwards Interlocking tamping tool holders.
  • the outer tamping tine holder is connected directly to a first pivoting drive and the inner tamping tine holder is connected to a second pivoting drive via a coupling arrangement mounted on the associated pivoting lever.
  • the arrangement of the coupling arrangement allows a further reduction in the space required. This makes the design of the tamping unit even more compact.
  • the coupling arrangement comprises a pivoting element which is rotatably mounted on the pivoting lever and a connecting element which connects the pivoting element to the inner tamping tool holder.
  • This arrangement is both robust and space-saving. Only rotary joints are used, which are easy to produce and have a long service life with little maintenance.
  • it can also be useful to use translationally mounted coupling elements.
  • a further simplification provides that the pivoting element is arranged to be pivotable about the first pivot axis.
  • the outer tamping pick holder and the pivoting element can thus be rotated about the same pivoting axis on the respective pivoting lever. This enables a compact design of the corresponding bearings with a continuous bearing shaft.
  • the function of the tamping unit is advantageously expanded if a driver is arranged on the connecting element and if the driver bears against a link element of the outer tamping tine holder when the inner tamping tine holder is swiveled up. In this way, when the inner tamping tool holder is swiveled up, the outer tamping tool holder is also swiveled up. For swinging up both For tamping tine holders it is sufficient to activate the second rotary drive while leaving the first rotary drive activated.
  • the outer tamping tool holder has a recess through which the coupling assembly is passed.
  • the outer tamping tool holder has a fork with a deepened recess in the direction of the pivot bearing, so that the recess is suitable for carrying out the coupling arrangement.
  • the inner tamping pick holder is also forked in the area of the associated pivot bearing, with the coupling arrangement being articulated in the middle.
  • a hydraulic cylinder is assigned to each tamping tool as a drive for adding and for applying vibrations.
  • a hydraulic control system is set up in such a way that an oscillating movement is superimposed on a positioning movement during a positioning process.
  • a chamber of the hydraulic cylinder is subjected to pulsating pressure. During an immersion process of the tamping tines in a ballast bed, only vibration is applied.
  • each tamping tool is assigned an auxiliary cylinder, each auxiliary cylinder being coupled to an eccentric drive for the purpose of applying vibrations.
  • a narrow design is also achieved here with auxiliary cylinders arranged side by side or one below the other.
  • a corresponding solution is disclosed in the publication AT 520 267 A1 .
  • An advantageous development provides that, for the simultaneous tamping of several sleepers, several tamping units are arranged one behind the other in a longitudinal direction of the track.
  • the narrow construction of the respective tamping unit enables this arrangement with unrestricted function of the swivel tines.
  • the tamping units are constructed in the same way. This simplifies production and reduces maintenance costs because fewer different spare parts are required. In addition, a higher-level control of the jointly arranged tamping units is facilitated. Due to the same kinematic properties of the individual tamping units, synchronous movement sequences can be easily implemented.
  • the tool carriers of the tamping units arranged one behind the other are advantageously mounted in a common unit frame so that they can be adjusted in height. This enables a joint lateral displacement or twisting about a vertical axis by adjusting the assembly frame. In this way, the tamping units arranged one behind the other can be positioned in a simple manner over a branching track of a switch.
  • each tool carrier of the tamping units arranged one behind the other can be separately adjusted in height by means of its own actuator.
  • the tamping units arranged one behind the other can be lowered to different depths. This allows a sill to be successively tamped down in different depth zones.
  • a lowering of individual tamping units can be suspended if there is not enough space for the tamping tines to penetrate.
  • Tamping unit 1 shown comprises a unit frame 2, which is laterally displaceably mounted on a machine frame 3 of a track construction machine not described in detail.

  • a driver 29 is fastened to the connecting element 25 as a counter-element. This driver 29 rests on the link element 28 . During an upward pivoting process, the driver 29 slides along the link element 28 and thus causes the outer tamping tool holder 15 to pivot as well.
