Definitions

  • the invention relates to a method for tamping several sleepers of a track mounted in a ballast bed by means of several tamping units arranged one behind the other on a machine frame of a track tamping machine with pairs of opposite tamping tools, with only one sleeper being tamped during a tamping process by means of the respective tamping unit.
  • the invention relates to a machine for carrying out the method.
  • tracks with a ballast bed are regularly processed using a tamping machine.
  • the tamping machine travels over the track and raises 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 pushed under the respective sleeper and compacted.
  • Mainline tamping machines in particular use tamping units for tamping several sleepers at the same time.
  • the high processing speed achieved in this way enables a track to be processed in short track closures.
  • Modern tamping machines are also characterized by low wear and tear on both the tamping unit and the ballast.
  • AT 513 034 A1 discloses a method and a generic track tamping machine with a plurality of tamping units arranged one behind the other. Each tamping unit is height-adjustable in one common subframe arranged. A tamping process begins when the tamping units are lowered together. This joint lowering of adjacent tamping units for tamping of adjacent sleepers in the longitudinal direction of the machine takes place with a time delay. This facilitates in particular the immersion of immediately adjacent tamping picks that are immersed in a common sleeper compartment.
  • Adaptation to different sleeper pitches is only possible to a limited extent with such tamping units by changing the opening width of the tamping tools that are arranged in pairs opposite one another. Specifically, the lower lever arms of the non-contiguous tamping tools are moved outwards. The tamping tines attached to the lower lever arms are tilted, with disadvantages when plunging into the ballast bed and when the tamping tines are raised.
  • the invention is based on the object of improving a method of the type mentioned at the outset in such a way that high-quality stuffing results are achieved with flexible adaptation to different threshold divisions. It is also an object of the invention to specify a correspondingly improved track tamping machine.
  • a sleeper pitch of the sleepers to be tamped is specified to a control device for controlling longitudinal actuators, that before a tamping process the tamping units are positioned relative to one another by means of the longitudinal actuators in the longitudinal direction of the machine in order to adapt the positions of the tamping units to the specified sleeper pitch and that during the tamping process, sleepers that are not directly behind one another are tamped. Due to the spacing of the tamping units from one another in the longitudinal direction of the machine by more than one sleeper pitch, sufficient free space is available. Even with different Each tamping unit can be positioned exactly over a sleeper to be tamped without changing the position of the tamping tools.
  • tamping tools of the tamping units positioned one behind the other dip into the same sleeper compartment. This protects both the tamping units and the ballast.
  • Each tamping tool on the tamping tools performs the same immersion process, with little resistance to penetration and without being influenced by the tamping tools of the other tamping units.
  • Even with narrow sleeper compartments there are sufficient sideways to ensure optimal tamping of the respective sleeper.
  • These uniform conditions for all tamping picks result in a homogeneous multi-sleeper tamping with consistent, optimized compaction processes. For example, a migration of the ballast between a pick plate arranged at the respective end of the tamping pick and a lower edge of the sleeper is avoided because sufficient supplies can always be provided.
  • each tamping unit during a tamping process force and/or motion sensors arranged on an associated tamping tool are used to record curves of a ballast force acting on the tamping tool over a distance covered by the tamping tool, in order to derive a parameter for compaction control from this. Due to the spacing in the longitudinal direction of the machine, which is a multiple of the sleeper pitch, each tamping unit delivers precise measurement results without being influenced by the other tamping units. Thus, the methods described in the publication AT 520056 A1 for determining a parameter can be used equally for all tamping units. This also enables continuous compaction control in real time for the present multi-sleeper tamping.
  • a further improvement provides that, before a tamping cycle, the positions of the sleepers are detected by means of a sensor device arranged on the tamping machine and that from the detected Positions the current threshold division is derived.
  • a corresponding sensor device is known from AT 519739 A4. In this way, the tamping unit positions are automatically adjusted to different sleeper pitches.
  • the sensor device is also suitable for further automation of the multi-sleeper tamping. Sensor data is used to specify a tamping position for each tamping tool. An operator confirms suggested tamping positions or monitors fully automatic operation of the tamping machine.
  • a track grid formed from the sleepers and rails fastened to them is lifted before tamping by means of a lifting and straightening unit and aligned laterally, with a vertical position and a transverse position of the rails being recorded by means of a measuring device positioned in front of the foremost tamping unit. Due to the leveling acceptance at the foremost tamping unit, the track grid is brought into a specified track position with high accuracy.
  • a further improvement provides that with three tamping units arranged one behind the other at a distance of twice the sleeper pitch, all three tamping units are moved forward by three sleeper pitches in the working direction after the first tamping process, so that during a second tamping process only the foremost and middle tamping units are used for tamping that after the second tamping process all three tamping units are again moved forward by three sleeper divisions in the working direction and that during a third tamping process all three tamping units are used for tamping.
  • every sleeper is efficiently padded right from the start of the construction site. It forms at the beginning of the edited Track section from a uniform ramp compared to the subsequent unprocessed track.
  • the use of three tamping units represents an optimum between the required length of the track tamping machine or the distance between the rail carriages and the achievable working speed.
  • the track panel section that is lifted and to be fixed also has an optimum length with regard to the bending radii that occur.
  • a further improvement of the method provides that for the tamping of Y-sleepers, one rail track is tamped with the foremost tamping unit and that the other rail track is tamped with the tamping unit positioned behind it. This further expands the possible uses of the track tamping machine.
  • a track construction machine comprises a plurality of tamping units arranged one behind the other on a machine frame for the simultaneous tamping of a plurality of sleepers on a track, with each tamping unit being controlled by a vertical actuator height-adjustable tool carrier, on which tamping tools are mounted in pairs opposite one another, which can be made to oscillate via drives and can be ordered in relation to one another.
  • the machine is set up to carry out one of the methods mentioned in such a way that the tamping units can be displaced relative to one another in the longitudinal direction of the machine by means of longitudinal actuators and that the longitudinal actuators can be controlled by means of a common control device in order to position the tamping units at a distance from one another which is a multiple of one corresponds to predetermined threshold division.
  • Such a multi-sleeper tamping machine can be used for the flexible, efficient and high-quality processing of mainline tracks.
  • each tamping tool comprises a tamping pick at a lower free end, which is aligned vertically in an immersion position.
  • This achieves a quicker and gentler immersion process into the ballast bed, with less stress on the tamping tools and other aggregate components. Due to the low immersion volume, the ballast is also exposed to low loads, which avoids unwanted crushing of the ballast. In addition, the gentle immersion process leads to low noise emissions.
  • the faster immersion process compared to the obliquely immersing tamping tine increases the overall working speed of the machine.
  • the vertically aligned tamping picks leave less of a cavity into which the ballast can slide when lifting out of the ballast bed. As a result, the compression achieved is retained.
  • a further improvement provides that a main frame supported on chassis is movable on the track and that the machine frame with the tamping units is arranged to be displaceable in relation to the main frame in the longitudinal direction of the machine.
  • the main frame with driver's cabs, traction drive and other heavy equipment moves continuously along the track, which means that these masses do not have to be braked and accelerated with every tamping cycle.
  • Only the machine frame with the tamping units is stopped during a tamping cycle, resulting in a displacement against the direction of travel compared to the main frame.
  • the machine frame is moved to the new tamping position, with a shift in the direction of travel compared to the main frame.
  • the respective tamping unit is constructed symmetrically with respect to a plane of symmetry orthogonal to the machine longitudinal direction. This results in the same vibration amplitudes of the tamping tools, which are arranged in pairs opposite one another. During the tamping process, the corresponding tamping tines act simultaneously on the gravel grains located between them (same tamping tine dynamics in counterstroke). The result is homogeneous compaction with effective energy input into the ballast bed.
  • the tamping units arranged one behind the other are advantageously constructed in the same way.
  • the resulting identical unit parts simplify the construction of the machine. As a result, maintenance work can be carried out with less effort in a shorter time, with fewer different spare parts being required overall.
  • each tamping unit comprises several tamping units arranged next to one another transversely to the longitudinal direction of the machine, which are fastened to a common carrier device and in particular have separately height-adjustable tool carriers. This increases the flexibility of use of the machine. For example, in switch sections or in the case of obstacles in the track, only those tamping units are activated that have tamping tools that can be immersed in a free sleeper compartment.
  • one of the tamping units arranged one behind the other is fastened to the machine frame and if the other tamping units are mounted on longitudinal guides coupled to the machine frame.
  • the mechanical connection of the tamping units with the machine frame is simple in this way, without the Restrict displacement of the tamping units to each other.
