    Tamping unit and method for tamping sleepers on a track
    TECHNICAL FIELD The invention relates to a tamping unit for tamping sleepers on a track, with a tool holder mounted on a unit frame in a height-adjustable manner by means of a drive, with pairs of two opposing tamping tools, which can be provided about a respective swivel axis and also by means of a vibration drive can be set in vibration. In addition, the invention relates to a method for stuffing sleepers of a track with the tamping unit.
    PRIOR ART [02] Tamping units for tamping sleepers on a track are already known several times, e.g. B. by AT 500 972 B1 or AT 513 973 B1. Vibrations acting on the tamping ax can either be generated mechanically by an eccentric shaft or by hydraulic impulses in a linear motor.
    [03] The tamping tools that can be used in the tamping units of track tamping machines are immersed in the ballast between the individual sleepers and, in order to stuff the ballast under the sleepers, are provided in pairs to one another. Large forces are transferred to the tamping tools, especially when tamping a non-renewed ballast bed, which is often completely encrusted, a very high resistance to penetration must often be overcome when penetrating into the ballast bed and the tamping tools may be damaged.
    [04] As is known, optimal stuffing frequencies for compaction are between 25-40 Hz, whereby penetration of the stuffing pick into the ballast can be carried out more easily at higher frequencies.

    SUMMARY OF THE INVENTION [05] The object of the invention is to provide an improvement over the prior art for a tamping unit and a method of the type mentioned at the beginning.
    [06] According to the invention, this object is achieved by a tamping unit according to claim 1 and a method according to claim 4. Advantageous further developments of the invention result from the dependent claims.
    [07] 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 are easier to penetrate into the ballast. The vertical vibration results in a lower plunge. This means less wear 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 vertical vibration is around 35Hz.
    [08] The drive and the associated vibration drive are advantageously designed as a common hydraulic cylinder in which a pressure chamber is acted upon by a pulsating fluid flow. This creates the possibility of adapting existing tamping units. Specifically, an existing hydraulic cylinder is pulsed to lower or raise the tool holder during an immersion process.
    It is advantageous if a servo valve or proportional valve controlled by a control is arranged on the hydraulic cylinder. Valves of this type are suitable for pulsating control, the direct attachment to the hydraulic cylinder precluding the damping effect of hydraulic lines.
    [10] It is also advantageous if the vertically acting vibration is switched on automatically when immersed and automatically switched off when a preset stop depth is reached or when the tamping tools start to be provided. This leads to an increase in efficiency of the / 9

    Stuffing unit, whereby the additional movement of the tamping tools takes place in the proven manner.
    BRIEF DESCRIPTION OF THE DRAWINGS [11] The invention is explained below by way of example with reference to the accompanying figures. In a schematic representation:
    Fig. 1 is a schematic side view of a tamping unit
    Fig. 2 is a detailed view of a tamping tool
    DESCRIPTION OF THE EMBODIMENTS [12] A tamping unit 1, shown in simplified form in FIG. 1, for tamping sleepers 2 of a track 3 has pairs of two tamping tools 5, each of which can be pivoted about a pivot axis 4 and which are on a
    Tool carrier 6 mounted and each connected to an auxiliary drive 7. Each auxiliary drive 7 is connected to a vibration drive 8 designed as an eccentric. Horizontal vibrations 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 holder 6 is mounted on a unit frame 12 by a drive 10 with an associated vibration drive 11 so that it can be adjusted in height. A servo valve 17 including control 16 is assigned to the drive 10.
    2, a track 3 including rails 3 and sleepers 2 together with ballast bed 14 is shown. The stuffing tool 5, which is set into a vertical vibration (arrow 15) by the vibration drive 11, is moved during the immersion process by means of the drive 10 from a raised position (dashed line) to a lowered position (full line). The amplitude of the darning tools set in vertical vibration is in the millimeter range (dotted line).
    [14] The drive 10 and the vibration drive 11 are advantageously combined in a common hydraulic cylinder. The hydraulic cylinder is pulsed with a pulsating fluid flow / 9 during an immersion process
    acted upon, whereby the lowering movement of the tool carrier 6, a vibration movement is superimposed.
    [15] The procedure and the mode of operation are described below.
    For easier penetration of the tamping tools 5 into the ballast bed 14, the vibration drive 11 assigned to the drive 10 is switched on and the tamping tools 5 are additionally set into a vertical vibration. The vertical vibration is only switched on automatically when the tamping tools 5 are immersed. The vertical vibration is switched off automatically when a preset depth is reached or at the start of the supply.
