Definitions
- the invention relates to a tamping unit for tamping under sleepers of a track, with a tool carrier that is height-adjustable by a drive and mounted on an assembly frame, with pairs of two opposing tamping tools that are mounted on the tool carrier and can be provided to each other around a respective pivot axis as well as by a vibration drive can be set in vibration.
- the invention also relates to a method for tamping under sleepers of a track with the tamping unit.
- Tamping units for tamping under sleepers of a track are already known several times, such. B. by AT 500 972 B1 or AT 513 973 B1 . Vibrations acting on the tamping tines can be generated either mechanically by an eccentric shaft or by hydraulic impulses in a linear motor.
- the tamping tools that can be used in the tamping units of track tamping machines are dipped into the ballast between the individual sleepers and placed in pairs under the sleepers for tamping under the ballast.
- great forces are transferred to the tamping tools, especially when tamping a ballast bed that has not been renewed and which is often completely encrusted, a very high resistance to penetration often has to be overcome when penetrating the ballast bed, and the tamping tools may be damaged.
- optimal tamping frequencies for compaction are between 25-40 Hz, whereby penetration of the tamping ax into the ballast can be carried out more easily at higher frequencies.
- the invention is based on the object of specifying an improvement over the prior art for a tamping unit and a method of the type mentioned above.
- the invention provides that the drive for lowering the tool carrier is assigned a vibration drive which sets the tamping tools in a vertically acting vibration.
- a major advantage here is that the tamping tools penetrate the ballast more easily.
- the vertical vibration results in less immersion impact. This causes less wear and tear on the tamping tools, the service intervals are extended and the stress on the bearings of the tamping unit is reduced.
- the optimal frequency of the vertical vibration is around 35Hz.
- the drive and the associated vibration drive are advantageously designed as a common hydraulic cylinder in which a pressure chamber is subjected to a pulsating fluid flow. This creates the possibility of adapting existing tamping units. Specifically, an existing hydraulic cylinder for lowering or raising the tool carrier is controlled in a pulsating manner during an immersion process.
- a servo valve or proportional valve controlled by means of a controller is arranged on the hydraulic cylinder.
- Such valves are suitable for pulsating control, the direct attachment to the hydraulic cylinder excluding a damping effect of hydraulic lines.
- FIG. 1 An in Fig. 1 A simplified tamping unit 1 for tamping under sleepers 2 of a track 3 has pairs of two tamping tools 5 which can be pivoted about a pivot axis 4 and which are mounted on a tool carrier 6 and each connected to an auxiliary drive 7. Each additional drive 7 is connected to an oscillating drive 8 designed as an eccentric. Horizontal vibration oscillations are thus generated, which are transmitted to the ballast 9 to be compacted via the auxiliary drive 7 and the respective tamping tool 5.
- the tool carrier 6 is supported in a height-adjustable manner on an assembly frame 12 by a drive 10 with an associated vibration drive 11.
- a servo valve 17 including control 16 is assigned to the drive 10.
- a track 3 comprising rails 13 and sleepers 2 together with ballast bed 14 is shown.
- the amplitude of the tamping tools set in vertical vibration is in the millimeter range (dotted line).
- the drive 10 and the vibration drive 11 are advantageously combined in a common hydraulic cylinder.
- the hydraulic cylinder is operated with a pulsating flow of fluid during an immersion process acted upon, whereby the lowering movement of the tool carrier 6 is superimposed on a vibration movement.
- the vibration drive 11 assigned to the drive 10 is switched on and the tamping tools 5 are additionally set into vertical vibration.
- the vertical vibration is only switched on automatically in the phases of the dipping of the tamping tools 5.
- the vertical vibration is switched off automatically when a preset tamping depth is reached or when the tamping tool begins.
