Definitions

  • the invention relates to a tamping unit for tamping a group of adjacent sleepers on a track, comprising tamping tools arranged one behind the other in a working direction.
  • Each tamping tool is pivotably mounted on a height-adjustable tool carrier about an associated pivot axis.
  • Positioning drives for individual tamping tools are configured for a first positioning movement and for an opposite second positioning movement.
  • For tamping a respective sleeper several tamping tools are arranged side by side in a row at several locations.
  • the invention relates to a method for operating the tamping unit.
  • tracks with ballast are regularly tamped using a tamping machine.
  • the tamping machine travels along the track and raises the track grid, formed by sleepers and rails, to a desired level using a lifting/leveling unit.
  • the new track position is secured by tamping the sleepers using a tamping unit.
  • the tamping unit comprises tamping tools with tamping picks that, during a tamping process, are immersed in the ballast bed under vibration and are moved towards each other using adjusting drives. In the process, ballast is pushed under the respective sleeper and compacted.
  • Line tamping machines in particular, use tamping units to simultaneously tampe a group of adjacent sleepers.
  • Such tamping units are, for example, used in the US 3 589 297 A , the EP 3 207 179 B1 , the EP 3 545 134 B1 or the EP 3 237 681 B1
  • the high level of Processing speed allows a track to be worked through in short closure breaks.
  • the invention is based on the object of improving a tamping unit of the type mentioned above to achieve efficient operation. Furthermore, the ballast in the sleeper compartments and the tamping unit itself are to be protected during a tamping process. A further object of the invention is to provide a corresponding method.
  • Each tamping tool located between a frontmost tamping tool and a rearmost tamping tool is assigned a tamping drive designed for two tamping movements in opposite directions.
  • several tamping tools are arranged next to each other in a row.
  • each of the tamping tools arranged one behind the other is arranged in a row with adjacent tamping tools for sole immersion into a sleeper intermediate compartment.
  • four tamping tools, each with two tamping picks are arranged next to each other in each row.
  • two tamping tools per row are immersed. Tamping tools are inserted into a sleeper compartment on both sides of a respective rail of the track in order to tamp a sleeper adjacent to the respective sleeper compartment.
  • two tamping tools In conventional tamping units for the simultaneous tamping of several adjacent sleepers, two tamping tools, arranged directly behind one another or diagonally offset from one another, penetrate the ballast bed in at least one sleeper gap.
  • the tamping tools vibrate to loosen the ballast bed during the penetration process.
  • wear can occur due to the close proximity of the vibrating tamping tools within the same sleeper gap.
  • increased ballast abrasion, even fragmentation occurs.
  • the tamping tools themselves are also subject to increased wear due to this stress.
  • the increased formation of fines in the ballast bed has an adverse effect on the elasticity of the track, the ballast modulus, and the shear strength of the ballast.
  • Track stability deteriorates due to the increasing inhomogeneity and reduced drainage of the ballast. This results in additional stress on the superstructure and the rail vehicles traveling on the track.
  • the fines harden the ballast bed, making it difficult for the tamping tools to penetrate during subsequent tamping work and increasing the loads on the tamping unit.
  • the tamping tools arranged side by side in a row are subjected to vibration and plunge into the same sleeper gap, these tamping tools are spaced far enough apart that the forces exerted by these tamping tools on the ballast grains do not cause destructive stresses on the ballast. Therefore, during a tamping process using the tamping unit according to the invention, far fewer ballast fines are formed, resulting in a durable track bed with a high resistance to lateral displacement. The ballast mode and the gravity strength of the ballast bed are maintained. The protection of the Ballast and improved drainage of the ballast bed result in longer ballast cleaning and ballast replacement intervals.
  • penetration resistance is lower because only the ballast in front of one row of tamping picks needs to be displaced in each intermediate compartment. This reduces the mechanical stress on the tamping unit and the wear on the tamping picks, resulting in longer service and maintenance intervals.
  • the lower penetration resistance allows for smoother penetration into the ballast bed with a lower lowering speed of the tamping tools. This reduces the plunge shock that occurs when the tamping pick tips hit the ballast surface and can lead to the splitting of ballast grains.
  • ballast tools require less work to fill the cavities created under the sleepers during the track lifting process.
  • all tamping tools arranged one behind the other are mounted on a common tool carrier, so that only one height adjustment drive is required to lower and raise the tamping tools together.
  • the number of moving components is reduced, resulting in reduced component wear.
  • all adjacent pivot axes of the tamping tools arranged one behind the other are spaced apart by a distance that approximates a sleeper pitch of the track to be tamped. If the tamping unit is intended for tamping tracks with different sleeper pitches, an average of these sleeper pitches is selected to determine the distance between the adjacent pivot axes. Adjustments to larger or smaller Sleeper spacing is achieved by slightly pivoting the respective tamping tool before penetration. The uniform positioning movements of all tamping tools resulting from this arrangement lead to optimal filling of cavities beneath the sleepers to be tamped. Furthermore, tracks with a narrow sleeper spacing or with particularly wide sleepers are easy to work with. Even with narrow sleeper spacing, optimal tamping is achieved because more than half the width of the sleeper spacing is available for the positioning path and only one row of picks penetrates into each sleeper spacing at a time.
  • the respective auxiliary drive is a hydraulic cylinder for simultaneously generating vibration and an auxiliary movement.
  • Pulsating pressure on the respective hydraulic cylinder at a frequency between 30 Hz and 45 Hz requires a hydraulic system with servo or proportional valves and continuous displacement measurement of the respective piston rod. If necessary, an oil cooling system must be adapted to dissipate the heat generated by the pulsating pressure.
  • the respective auxiliary drive is coupled to the associated tamping tool on the one hand and mounted on an eccentric shaft for generating vibration on the other.
  • This vibration generation by means of a rotating eccentric shaft leads to high process reliability because the vibration amplitude is maintained even with larger reaction forces from the ballast bed.
  • An improvement to this variant is achieved by a configuration in which all auxiliary drives of the tamping tools arranged one behind the other are mounted on a common eccentric shaft. This is particularly useful in a version with a common tool carrier. Due to the reduced complexity of using only one vibration drive, component wear and the risk of malfunctions are reduced.
  • the respective auxiliary drive is mounted on the eccentric shaft with an adjustable eccentricity, so that the vibration amplitude can be adjusted while the rotary drive of the eccentric shaft is running. Eccentricity can be reduced to zero to completely eliminate vibration. A corresponding adjustability of the eccentricity is included in the AT 517999 A1 described.
  • the auxiliary cylinders mounted on the eccentric shaft are depressurized to eliminate vibration of the associated tamping tools. The tamping tools, immersed in the ballast bed, are held in position by the adjacent ballast.
  • tamping tools are arranged one behind the other, with all tamping tools being arranged symmetrically with respect to a plane of symmetry running perpendicular to the working direction.
  • the middle tamping tools with respect to the working direction are each coupled to a support cylinder for two opposing support cylinders.
  • the tamping picks of these middle tamping tools have pick plates with two working surfaces facing away from each other.
  • three adjacent sleepers can be tamped in one tamping cycle.
  • the new tamping unit comprises fewer support drives, thereby reducing wear and the risk of malfunctions.
  • three tamping tools are arranged one behind the other, with the frontmost and rearmost tamping tools, in particular, being arranged symmetrically with respect to a plane of symmetry running perpendicular to the working direction.
  • the middle tamping tool is coupled to the positioning cylinder for two opposing positioning movements and features a pick plate with two opposing working surfaces.
  • an upper lever arm of the middle tamping tool is tilted forwards or backwards and coupled to the inclined positioning cylinder.

  • the track construction machine 1 shown is designed as a track tamping machine for tamping sleepers 4 stored in a ballast bed 2 of a track 3.
  • the track construction machine 1 comprises a machine frame 6 supported on rail carriages 5, on which a tamping unit 7 is arranged. By means of this tamping unit 7, A group of several adjacent sleepers 4 can be tamped during a tamping process.

Several tamping tools 17 are mounted on the tool carrier 14, one behind the other, pivotable about a respective pivot axis 18 with respect to a working direction 16. The adjacent pivot axes 18 are spaced apart by a distance a that approximates a sleeper pitch t of the track 3 to be tamped.

Preferably, two tamping picks 20 are mounted side by side in a tamping pick holder 21 of the respective tamping tool 17.
  • the upper lever arm is pivotally connected to a first end of an auxiliary drive 22.
  • a second end of the auxiliary drive 22 is mounted on an eccentric shaft 23 of a vibration drive 24.
  • the respective auxiliary drive 22 is preferably a hydraulic cylinder connected to a hydraulic system of the track construction machine 1.
  • auxiliary drives 22 of the tamping tools 17 arranged one behind the other are mounted on the same eccentric shaft 23.
  • each auxiliary drive 22 is mounted on an associated eccentric shaft section with its own eccentricity.
  • An adjustable sleeve is mounted on each of these eccentric shaft sections to adjust the respective eccentricity.
  • a corresponding mechanism is described in the AT 517999 A1 described.
  • the respective adjusting drive 22 is attached directly to the tool carrier 14 and is configured to simultaneously generate a vibration and an adjusting movement 25.
  • the eccentric shaft 23 with adjustable eccentricity also allows various vibration parameters to be adjusted in this variant. In particular, the vibration can be switched on and off at any time. Another option is to suspend the vibration transmission of the eccentric shaft 23 by depressurizing the respective auxiliary drive 22. The associated tamping tool 17, immersed in the ballast bed 2, is then held in position by the adjacent ballast.
