Definitions

  • the invention relates to a track tamping machine for compacting the ballast bedding of a track, with at least two tamping units per track tamping machine side, which can be displaced transversely to the longitudinal direction of the track tamping machine with a transverse displacement device, for tamping under the track and with a lifting and straightening device arranged between the rail bogies in the working direction, preferably in front of the tamping units Leveling and straightening the track and possibly the branching line of a switch.
  • Track tamping machines are machines that correct the position of switches and / or tracks.
  • measuring systems are used that measure the actual track height, the actual track direction and the actual cant position of the track during work and compare them with specified target values.
  • the track grid With the help of a lifting and straightening device, the track grid is raised and laterally aligned until the difference between the specified target position and the actual position is zero. This geometric position is fixed by compressing the ballast under the sleepers on the left and right of the rails with the help of a tamping unit.
  • the track grid is lifted and straightened using appropriate hydraulic lifting and straightening cylinders with proportional or servo controls. Turnouts have a continuous track and a branching track as a special feature.
  • the so-called tongues change the direction of movement of the moving train.
  • the intersection area between the continuous rail and the branching rail is called the focal point.
  • point tamping machines with split tamping units so-called split-head tamping units.
  • split-head tamping units During the tamping of a turnout, the respective outer unit of one side can be pivoted outwards in the direction of the branching track for tamping the same.
  • a track tamping machine for compacting the ballast bedding of a track with at least two tamping units per track tamping machine side for tamping the track, which can be displaced transversely to the longitudinal direction of the track tamping machine with a transverse displacement device U.S. 4,445,437
  • the outer tamping unit with the guides assigned to it can be displaced transversely to the longitudinal direction of the track tamping machine with an adjusting drive and the inner tamping unit can be displaced on the same guides independently of the outer tamping unit with an adjustment drive transversely to the longitudinal direction of the track tamping machine.
  • EP 0 386 398 B1 shows an embodiment of a transverse displacement device for tamping units on a sliding guide common to the tamping units, which is characterized by a limited transverse displacement path within the machine frame.
  • the common transverse guidance in a plane lying parallel to the track plane is characterized by low bending stiffness, since the guides are horizontal to the track plane.
  • the rotating device is formed by four guide rollers that can be rotated about vertical axes, with centering taking place via a circular segment-shaped guide surface of the machine frame.
  • EP 1 846 616 B1 shows an embodiment of the transverse displacement device which shows four transversely displaceable units on a further rotatable intermediate frame which in turn has an additional transverse displacement so that a greater transverse displacement path at least of the respective outer unit can be achieved.
  • the displacement path of the respective inner unit remains limited.
  • the vertical limited flexural rigidity of the units guided in this way leads to vibratory behavior when tamping due to the immersion forces, which means an increased permanent bending fatigue strength stress.
  • the rotating devices carried out so far are complicated in structure and require increased maintenance.
  • the limitation of the lateral displacement path of the inner unit on one side and the limited displacement paths in general prevent the clogging of a switch (main track and branching track) in one passage.
  • the state of the art is two operations for tamping a switch.
  • Well-stuffed tracks must be stuffed to the left and right of the rail. Therefore, in the first step, the Main track and in the branching line of the turnout only the inner area of the outer rail of the branch is stuffed. In a second step, those areas are stuffed that could not be processed in the first step.
  • the outer unit part is located on a pivotable carrier. This support arm must be designed to be longitudinally displaceable so that the unit position can be adjusted to the inclined long sleepers in the switch. The unit which is located on the support arm must also be designed to be rotatable on this support arm. Such designs are mechanically complex and cause the unit to vibrate when it is immersed and tamped.
  • Another generic prior art is from EP 0 386 398 B1 and the EP 0 455 179 A2 known.
  • the invention is therefore based on the object of specifying a transverse displacement device for units that allows both units on one side of the machine to be moved independently so that the main line and the branching line of a switch can preferably be tamped in a single operation.
  • the rigidity of the guidance of the units in the longitudinal direction of the track, in the vertical direction and also the torsional rigidity should be increased. According to an advantageous further development of the invention, it should be possible to adapt the tamping units to the inclined long sleepers of a switch, if necessary.
  • both tamping units on each track tamping machine side are assigned at least two guides, in particular slide rods or slide tubes, which are offset from one another in terms of their height and in the longitudinal direction of the track tamping machine, the respective outer tamping unit with the guides assigned to it with a Adjustment drive is displaceable transversely to the longitudinal direction of the track tamping machine and the inner tamping unit can be displaced on the same guides independently of the outer tamping unit with an adjustment drive transverse to the longitudinal direction of the tamping machine, the guides of the tamping units on opposite sides of the tamping machine resting in a common guide seat.
  • the transverse shifting device allows both units on one side of the machine to be shifted independently, so that the main line and the branching line of a switch can be tamped together.
  • the inner tamping unit can therefore be displaced on the associated guide of the outer tamping unit. Both tamping units can be relocated either together or individually.
  • a turntable is attached to a girder if necessary, to which a guide receptacle can be assigned.
  • the guides in particular slide rods or slide tubes, with which the laterally outer assembly parts are firmly connected, are mounted in this guide receptacle.
  • the respective inner assembly parts slide on these common slide rods or slide tubes.
  • the movements are carried out via transverse displacement drives.
  • the laterally inner unit can be displaced transversely up to the limit by the laterally outer unit.
  • the slide rods or slide tubes of the left and right units are spatially arranged independently of one another so that they do not interfere with one another and that the at least two guides are provided not only in the longitudinal direction of the track tamping machine but also vertically offset from one another in height.
  • the assembly frames of the tamping units preferably have clearances, in particular holes, for the guides of the tamping units of the respective other track tamping machine sides, in order to make the best possible use of the permissible clear space of the railroad tracks.
  • This design enables considerably longer transverse adjustment paths to be achieved.
  • Such tamping machines are used to set up and tamp a track.
  • the tamping units of both Machine sides are shifted beyond the machine frame to the outside.
  • both the main strand and the branching strand can be completely stuffed up to approximately the level of the frog at a switch position in one operation.
  • the transverse displacement device with the transversely displaceable units is also designed to be rotatable about the vertical axis via a turntable. Due to the at least two sliding guides that are offset in height with respect to the track level, a high level of stability of the guided units is achieved.
  • the advantage of this embodiment according to the invention is that the transverse displacement device achieves greater transverse displacement paths for the two units on one side. Furthermore, it is advantageous that the inner unit on one side can be pushed out to the limit by the outer unit on the same side, which is why both the main strand and the branching strand can be processed in a switch in one operation.
  • the execution of height-offset sliding guides advantageously leads to a higher rigidity of the device for the cantilevered tamping units.
  • the use of a turntable device according to the invention also increases the range of rotation of the entire device and, due to the simple structure, promises lower maintenance and cost outlay.
  • a track tamping machine 22 ( Fig. 1 ) with main girders 12 has tamping units 41 with transverse displacement device 1, a lifting and straightening unit 26 and a track lifting drive 25 as well as a track straightening drive 33.

  • a turntable 14 is attached to cross members 13. With this turntable 14, the entire transverse guide device can be rotated 15 about the vertical axis (by at least 20 °) by means of the rotary drive 35.
  • a transverse guide receptacle 34 is mounted on the underside of the turntable 14.
