    The invention relates to a tamping unit for a tamping machine with respect to a Stopfaggregatrahmen along guides height-adjustable guided carrier on which are designed as rocker Stopfwerkzeugpaare pivotally mounted, for dipping into a ballast certain stuffing tools with a vibratory drive in opposite directions drivable and hydraulically be provided to each other, wherein each of the stuffing tools of a Stopfwerkzeugpaares is associated with a Beistellantrieb.
    Tamping units penetrate with gravel tools the gravel of a track bed in the area between two sleepers (intermediate compartment), in the area of the support of the threshold in the ballast under the rail and compact the ballast by a dynamic vibration of the tamping between the opposable tamping pegs that can be provided to each other. Tamping units can plug one, two or more sleepers in one work cycle (DE 24 24 829 A, EP 1 653 003 A2). According to the teaching of EP 1 653 003 A2, the auxiliary drives acting as a linear drive are designed in such a way that they not only provide a linear supply movement, but at the same time also in a manner known from AT 339 358, EP 0 331 956 or US Pat. No. 4,068,595 generate the vibration required for the tamping pimples. Thus, the additional speed, the vibration amplitude, its shape and the frequency can be specified.
    The movements of a tamping unit include the vertical immersion of the tamping pick in the ballast, the Beistellbewegung in which the tamping ends are closed to each other and the superimposed dynamic oscillation which causes the actual compaction of the ballast grains. It is known for the
    Sending movement Hydraulic cylinders which are connected via connecting rods with a vibration shaft with eccentricity and which are superimposed on the Beistellbewegung the vibratory oscillation (AT 369 455 B). These vibration shafts and connecting rods are mounted on rolling bearings, which regularly require more expensive maintenance. Other known solutions use linear vibration generation and auxiliary movement via hydraulic cylinders.
    The tamping units in use today have a very high and costly maintenance. Typically, the units are at least partially overhauled and maintained every season. Conventional tamping units have centrally located between the rails, stationary guide columns along which the tamping units are guided by means of Stopfkasten up and down. The guides are located in the middle of the rail. To the left and right of the center of the up and down moving stuffing box are the vibration waves over which the stuffing arms are driven with the stuffing tools via auxiliary cylinders, which are connected to the eccentric shaft via connecting rods. For a Einschwollenstopfaggregat four drives are required. This means eight drives for a two-aggregate single-station tamping machine, sixteen drives for a twin-shaft tamping machine, twenty four drives for a three-shaft tamping machine, and thirty-two drives for a four-shaft tamping machine. The number of drives increases the investment level, the maintenance effort and the probability of failure.
    The invention is therefore the object of tamping units of the type described with simple means such that the number of drives over the prior art can be reduced.
    The invention solves the problem set by the fact that several stuffing tools are combined to form stuffing units, which are between a tray for grasping a rail and mechanically connected to each other and that each rocker arm is associated with a stuffing unit and a Beistellantrieb and that the guides outside of the working area of Swing levers are arranged.
    The resulting reduction in the number of drives means a great practical advantage. In the case of a line tamping machine, it is generally not necessary for the stuffing arms, which are located inside and outside with respect to the rail, to work independently with the tamping tools and in each case have their own drive. Due to the mechanical connection of the stuffing arms located on the left and right of the rail, one side drive per stuffing unit is sufficient. Two stuffing units form a cooperating stuffing unit pair. The inventive design, the number of necessary Beistellantriebe can be halved. The usual center of the tamping arranged, stationary guide columns are so but in an arrangement of Beistellantriebe at this point in the way, which is why the guides are preferably arranged outside the working range of the rocker arm. If only one stuffing tool arm per stuffing unit is provided, the number of stuffing tool arms and the number of their maintenance-intensive bearings are also halved.
    Preferably, the oscillating drive and the Beistellantrieb are arranged in a central vertical plane of the carrier and the stuffing units and the Beistellantrieb is connected to the rocker arm for power transmission directly via a hinge pin.
    The vibration drives are designed according to a structurally simple solution as linear drives, in particular as a hydraulic cylinder, and at the same time form the Beistellantriebe.
    In the case of single-sill and two-shaft units, the guide columns of the guides are moved so far outwards that the plug drives find their place in the center of the tamping unit. In a three-shaft or vierschwollenstopfmaschine this design is not sufficient. For this case, it is proposed that the guides, in particular guide rods, engage directly on the respective support (the stuffing box) and are guided in fixed guides of the stuffing assembly frame. The guide columns are thus connected to the tamping unit and move up and down with the tamping unit. The guide columns are moved in a fixed guide. The known principle is therefore reversed. Instead of stationary guide columns with moving guide in the stuffing box, the guide columns, which are connected to the tamping unit are moved in a fixed guide. This has the further advantage that the Stopfrahmen which receives the units and in which the guide columns are fixedly mounted can now be smaller and thus forms a guide bracket, which receives the Stopfaggregat and leads. This results in better accessibility to Stopfaggregat itself plus weight savings. This embodiment of the invention also has the advantage that a one-piece Stopfwerkzeugarm can be performed with tool console for tamping.
    Furthermore, the oscillating levers, which hold the stuffing tools and combine them into stuffing units, can each have a common tool holder, in particular a carrier, for the tamping picks of a stuffing unit. For each stuffing unit only one stuffing tool arm has to be provided.
    Advantageously, a fully hydraulic linear drive is selected as a plug drive. In principle, however, it is also possible to carry out a conventional conventional plug drive with a continuous eccentric vibration shaft mounted on the outside with eccentricities located on the inside and engaging connecting rods connected to auxiliary cylinders. Per carrier (stuffing box) at least two guides are provided. To increase the stability, three or four guides can also be used. The fixed guides of the Stopfaggregatrahmens may lead to the formation of a Mehrfachstopfaggregats two or more carriers (stuffing boxes), which are independently displaced in the fleas.
    The main advantages of the invention are the simplified design, the FHalbie tion of the necessary Stopfantriebe, FHalbierung the stuffing arms and the associated storage, resulting in lower investment costs, reduced maintenance costs, a reduced probability of failure, a better accessibility to the tamping components for maintenance tasks as well as a weight reduction.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a two-shaft tamping unit according to the prior art in side view,
    2 shows an inventive two-shaft tamping unit with associated Stopfarmen and central drive in side view,
    3 shows a variant of a two-shaft tamping unit according to the invention in side view with moving guide columns and fixed guide with four linear-acting tamping drives and only four tufting arms and tool consoles for the tamping picks in side view,
    Fig. 4 is a Dreischwellenstopfaggregat in side view and Fig. 5, the Dreischwellenstopfaggregat of Fig. 4 with guide columns and associated fixed guide with six linear-acting Stopfantrieben and six Stopfarmen in perspective oblique view.
    In Fig. 1 - SdT - a known Zweischwellenstopfaggregat C is shown schematically, which has a continuous vibration wave on the four Beistelltriebe 5 via connecting rods on the left side of the eccentric shaft attack and four Beistelltriebe 5 attack via connecting rods on the right side of the eccentric shaft C. Left and right are the areas to the left and right of a rail of a track. A previously common Zweischwellenstopfaggregat C has each rail a total of eight Stopfarme 3 (four each for the left and four for the area to the right of the rail), eight Beistellzylinder 5, sixteen stuffing tools 6 and a vibration drive with pump 7 and flywheel. For the second track of the track is the same effort to drive. For this purpose, two vertical guides 8 in the area above the rail, a lifting-lowering drive 11 and a Stopfrahmen 9 are required.
    A tamping unit C, D, E, F for a tamping machine includes, inter alia, on a support 4, 18, 23 pivotally mounted, as rocking lever 3, 19 ausgebil finished tamping tool pairs 6, their specific for immersion in a ballast bed 24 tufting ends with a vibration drive 7, 17, 20 can be driven in opposite directions and hydraulically to each other via Beistelltriebe 5, with a Beistellweg B, beistellbar. The carrier 4,18, 23 is in a Stopfaggregatrahmen 9,14, which may also be shaped like a table, guided by guides 8, 15, 22 height adjustable and displaceable with an actuator 11 in the desired altitude. The stuffing tools 3 are designed as two-armed lever, which are pivotally mounted on the carrier 4,18, 23. One arm of the respective stuffing tool consists of the pivot arm 3, the tamping pick 6 and on the other lever arm engages a Beistelltrieb 5, a hydraulic cylinder to.
    2 shows an embodiment according to the invention of a two-shaft tamping unit D in which the tamping arms 3 are connected on the left and on the right of the rail 2 via continuous bolts 12, 13. The tamping tools 6 on the left and on the right of the rail 2 are combined to form tamping units S, which leave between them a compartment for embracing a rail and are mechanically connected to one another. In addition, a tamping unit (S), a vibratory drive 7, 17, 20 and a Beistellantrieb 5 is associated with each rocker arm 3.19 and the guides 8,15, 22 arranged outside the working range of the rocker arm 3,19.
    In each case, only one auxiliary cylinder 5 acts on the transverse bolts 12, 13. In order for a conventional two-shaft tamping unit D to be equipped with a centrally arranged vibration drive 7, the vertical guides 8 must be laid to the outside. In the area of the center of the vibration wave, the connecting rods, which are connected to the auxiliary cylinders 5, then engage. Thus comes a conventional Einschwellen- or two-shaft tamping unit D with only four side cylinders 5 instead of the eight provided in accordance with the prior art. The oscillating drive 7, 17, 20 and that of the auxiliary drive 5 are arranged in a central vertical plane of the carrier 4, 18, 23 and the stuffing units S, and the auxiliary drive 5 is connected to the oscillating lever 3, 19 for force transmission directly via a hinge pin 12, 13 , The unit D is raised or lowered via a lifting-lowering drive 11. The support arm 4 must be excluded in the region of the inner Stopfantriebe 5, so that the stuffing arms 3 transversely connecting pin 13 does not collide with the support arm. The support arm 4 runs on the outside via guides 10 on the guide columns 8. The guide columns 8 are so far outwardly offset that the outer stuffing arms 3 do not collide with the B side with them.
    3 shows the embodiment according to the invention of a two-shaft tamping unit E with only four stuffing arms 19, four auxiliary cylinders 20 and fixed to the Stopfaggregatträger 18 guide columns 15 which run in the non-illustrated with the machine frame of a tamping machine firmly connected frame-mounted guides 14. In order to compensate for deflections in the track curve, the tamping units E themselves are still moved to transverse guides 16. The vibration is superimposed in the embodiment shown in the hydraulic cylinders 20 by means of proportional valves 17 of the auxiliary movement B. The rocker arms 19 are made in one piece with a tool holder 25 for the tamping 6. The guides 15, in particular guide rods, engage directly on the respective carrier 18, project through the tamping unit frame 9,14 and run in fixed guides of Stopfaggregatrahmens 9, 14. The vibration drives 7,17, 20 are designed as linear drives, in particular as a hydraulic cylinder, and can at the same time form the Beistellantriebe 5.
    An inventive three-shaft unit F (Fig. 4, 5) consists of two independently movable up and down carriers 18, 23. Thus, the Dreischwellenstopfaggregat F can also be used as Einschwellenaggregat with irregular threshold division. In this case, only a partial unit 18 or 23 is lowered. The innermost, the other part of aggregate immediately adjacent rocker arm 19 can remain unactuated in Einschwellenmodus. Each tamping aggregate has its own guides 15, 22 which are located in an e.g. common leadership console of Stopfaggregatrahmens 14 run. In principle, this guide console can of course be carried out separately for each unit. In order to compensate for deflections in the track curve, the tamping units F themselves are still moved to transverse guides 16. The vibration is in the embodiment shown in the hydraulic cylinders 20 by means of proportional valves 17 of the auxiliary movement B Überla siege. The construction according to the invention of a three-shaft assembly F is shown in FIG. 5 in a perspective view.
