Definitions

  • the invention relates to a tamping unit for tamping under sleepers of a track, comprising a tamping unit with opposing tamping tools mounted on a lowerable tool carrier, which are each connected to an auxiliary drive for generating a auxiliary movement, an eccentric drive having an eccentric shaft being provided for generating a vibration movement.
  • tamping units are known for this purpose, which are arranged on track construction machines. During track tamping, the track construction machine moves along the track, with tamping ax attached to the tamping unit being lowered into sleeper compartments and provided.
  • a tamping unit is exposed to extremely high loads. Particularly during the immersion process in the ballast bedding and when the ballast is subsequently compacted below a sleeper, high load changes constantly occur, which place heavy demands on the vibration drive. Even between the tamping processes, the tamping unit can be heavily loaded by a vibration drive that is constantly in operation and the vibration transmitted to the tamping tools.
  • Tamping units for tamping under sleepers of a track are already widely known, such as. B. by AT 350 097 B .
  • a rotatable eccentric shaft serves as a vibration exciter, on which the auxiliary drives are articulated to transmit the vibrations to the tamping tines.
  • the invention is based on the object of specifying an improvement over the prior art for a tamping unit of the type mentioned at the beginning.
  • each additional drive is supported on a bracket which has an annular housing section which is mounted on an eccentric section of the eccentric shaft assigned to the additional drive.
  • the tamping unit has a particularly narrow and compact design.
  • the arrangement of the consoles means that the auxiliary drive and eccentric shaft are arranged one below the other to save space.
  • the respective housing section is mounted on the associated eccentric section by means of a roller bearing.
  • Rolling bearings are maintenance-free for their entire service life. Due to the low frictional torques and also low heating, no additional equipment - such as oil cooling - is required at normal speeds.
  • oil-air lubrication is provided for the roller bearing of the respective housing section on the associated eccentric section.
  • Such continuous lubrication with very small amounts of oil optimizes the service life of the rolling bearing. Due to the low oil requirement, only a small oil container is sufficient to ensure a long, uninterrupted service life.
  • Such an oil container can be arranged in the immediate vicinity of the eccentric drive.
  • the respective bracket is preferably designed in a P-shape with a support section pointing downwards. This configuration of the respective console enables a structurally simple and space-saving solution for the arrangement of the auxiliary drives.
  • the respective auxiliary drive is supported at one end on the associated bracket and is connected to the housing section of the bracket at a further point.
  • the further support of the ordering drive with respect to the bracket results in an improved distribution of loads and / or force transmission.
  • the individual components can then be optimally dimensioned and correspondingly easily implemented.
  • auxiliary drive is connected to the housing section of the associated bracket at the further point by means of a clamp-shaped connecting element. This provides a structurally simple and inexpensive way of securely anchoring the auxiliary drive on the console.
  • the two auxiliary drives are arranged next to one another below the eccentric drive with an opposite orientation.
  • the individual tamping modules of the tamping unit are designed to be as space-saving and compact as possible.
  • the respective tamping tool is advantageously connected to the associated auxiliary drive by means of a cranked lever arm.
  • the respective auxiliary drive is designed as a hydraulic cylinder.
  • the asynchronous, pressure-dependent provision of the tamping tines achieved in this way ensures even compression under all sleepers of a track to be tamped.
  • the hydraulic cylinders can be used to apply large forces with a small construction volume.
  • a further advantageous embodiment of the invention provides that the tamping unit comprises several structurally identical tamping units for the simultaneous tamping of several sleepers.
  • the narrow design is particularly advantageous here. This flexible design and variable combination of tamping units make the tamping units perfect Conditions in work deployment and adapted to customer requirements.
  • the modular design enables economical and efficient production.
  • Fig. 1 shows a simplified tamping unit 1 for tamping under sleepers 2 of a track 3 with a tool carrier 5 that can be lowered by a drive 4 and pairs of two opposite tamping tools 6.
  • Each tamping tool 6 is connected to an eccentric drive 9 via a swivel arm 7 and an auxiliary drive 8.
  • the additional drive 8 is supported in each case on a bracket 10, which has an annular housing section 11 which is mounted on a respective eccentric section 12 of an eccentric shaft 13 of the eccentric drive 9 assigned to the additional drive 8.
  • the respective swivel arm 7 has an upper swivel axis 14 on which the auxiliary drive 8 is mounted.
  • the respective swivel arm 7 is rotatably mounted on the tool carrier 5 about a lower swivel axis 15.
  • Such a tamping unit 1 is provided for installation in a tamping unit 16 in a track tamping machine or a tamping satellite that can be moved on the track 3.
  • Fig. 2 a side view of the stuffing unit 1 is shown, this also being in a lowered position.
  • the eccentric drive 9 together the two consoles 10 is arranged on an eccentric axis 17 within the tool carrier 5.
  • the eccentric shaft 13 is rotatably mounted on both sides via a bearing 18 within the tool carrier 5.
  • the respective pivot arm 7 is designed as a cranked lever arm so that the tamping tools 6 are aligned exactly opposite one another despite the eccentric sections 12 arranged next to one another.
  • Fig. 3 shows two tamping units 1 combined to form a tamping unit 16 and arranged in a unit frame 19. In this way it is possible to implement multi-sleeper units simply and flexibly by combining several tamping units 1 in a modular design.
  • Each module unit has its own drive 4 supported on the assembly frame 19, so that it can be lowered individually into a ballast bedding as required.
  • Fig. 4 shows a detailed view of the eccentric drive 9 including the eccentric shaft 13 and bearing 18 arranged on both sides.
  • the eccentric shaft 13 has two eccentric sections 12 with two eccentrics acting in opposite directions.
  • the console 10 is arranged on the respective eccentric section 12.
  • the associated auxiliary drive 8 is fastened to the respective console by means of screw connections 20.
  • Fig. 5 a detailed side view of the eccentric drive 9 together with the consoles 10 and auxiliary drives 8 is shown.
  • the two consoles 10 together with the annular housing sections 11 have an offset 21 due to the eccentrics acting in opposite directions.
  • This fastening is implemented here by way of example by means of a clip-shaped connecting element 22.
  • Fig. 6 shows the eccentric drive 9 shown in section.
  • a roller bearing 23 is on the respective eccentric section 12 arranged.
  • the housing section 11 has a screwed housing cover 24 on the outside. Oil-air lubrication is provided for lubrication. A slight excess air pressure is generated in the fired housing section 11 and a drop of oil is supplied via an oil bore 25 every 5-6 minutes.
  • an internal toothing 26 is provided for a non-positive connection with a drive motor. This can be carried out either hydraulically or electrically.
  • a section through the auxiliary drive 8 arranged on the console 10 is shown. This has a piston rod 27 in order to press the respective pivot arm 7 outward. In this way, the vibration generated by the eccentric drive 9 is superimposed on a positioning movement.
