Field of application of the invention

The invention relates to a track tamping machine with a height-adjustable stretch tamping unit for Unterstopfen two immediately adjacent thresholds, which has two mutually arranged in the machine longitudinal direction Stopfwerkzeugpaare for both sides of a rail, consisting of mutually adjustable and in the ballast - on both threshold longitudinal sides and on both Rail side submersible, vibrating tamping tools consist of double pick, wherein the located on the facing sides of the Stopfwerkzeugpaare inner stuffing tools are immersed in the same threshold compartment between two immediately adjacent thresholds and all Stopfwerkzeugpaare arranged with their Beistellantriebe tamping tools on a common tool support frame nd with a common height and vibration drive are connected.

Characteristic of the known technical solutions

Tamping units of this type for Giesstopfmaschinen for Unterstopfen two immediately adjacent thresholds of a track-according to DD-PS 44081 and DE-PS 1287100 the same applicant-have proven excellent in practice, since these so-called two-shaft tamping machines not only provide a much higher performance, but also cause a particularly reliable and uniform compression by the stuffing tools that can be dipped together in the same threshold compartment and at the same time move in opposite directions. Each Stopfaggregat the machine according to DE-PS 1287100 has, as seen in particular in the plan view of this reference, a total of four Stopfwerkzeugpaare on the ballast bed-each at the two threshold longitudinal sides and on the two rail sides - submersible, vibratable and especially as Double pimple trained stuffing tools exist. The stuffing tools of this on a height-adjustable tool support frame immediately adjacent in the machine longitudinal direction Stopfwerkzeug pairs or pairs groups are on Beistell drives in the machine longitudinal direction in pairs against each other adjustable and connected to a vibration drive and a height adjustment drive for common immersion in the ballast bed , When using such machines, difficulties can arise in particular in the case of severely irregular threshold spacing or else in the case of inclined sleepers or double sleepers under rail joints, since it is not always possible to position the tamping unit correctly and quickly in order to avoid disturbances in this regard.

It is also a track tamping machine for Unterstopfen rails and switches - according to AT-PS 303795 of the same applicant - known, the tamping units are also designed as two-shaft tamping units and their stuffing tools, however, are provided only with a single pimple. These individual pimples are each mounted for lateral pivoting in a direction perpendicular to the supply direction of the stuffing tool level on a plane perpendicular to this plane axis and connected to a hydraulically actuated piston-cylinder drive. This sideways pivoting tamping tools of the two-shaft tamping unit are stored together with the correction device on a projecting over the track to be corrected lind transversely to the track axis adjustable part des'Fahrgestellrahmens, in particular to achieve a particularly good fit in track switch areas. A Streckenstopfung is insufficiently possible with these machines, already because of the small number of pimples.

Finally, a track tamping machine-according to US-PS 4282815-known, which has two, each via a separate drive height-adjustable single tamping units to form a so-called stretch-two-shaft tamping machine,

- J -

Stopfwerkzeugpaare on the against each other beitellbaren, in the ballast bed on both threshold longitudinal sides and two rail sides submersible and vibrating tamping tools with double axles exist. This design requires a relatively large effort, since in addition to the two height adjustment drives for each Stopfwerkzeugpaar two vibratory drives - thus, as a whole, as seen in the plan of Figure 4, eight vibration drives - are erfoderlich. Furthermore, this construction has the disadvantage that the inner stuffing tools, due to the special nature of the Beistell- and vibration drive can not be arranged close enough so that difficulties in providing are given or not work at very different threshold distance working as a two-shaft tamping machine is possible. The individual units can probably be lowered separately and brought into use, but also the height adjustment of the units to each other by the structurally related strong projection or the protruding part is often hindered. These machines have also proven unsuitable in practice, either in use as two-shaft tamping machines and even less for working with the single tamping unit.

It is also - according to DE-OS 3205511 - a Gleisstopfaggregat known which has on a connected with a height adjustment drive tool support frame two adjacent in track transverse direction stuffing tools of a Stopfwerkzeug pair for use on a threshold side, one of which via an additional Height-shift drive the height is formed on and pulled out. With this so-called half-aggregate, only one half-side of the rail / sleeper intersection area to be worked on is to be supported. Such tamping units are provided only for the half-side single-threshold clogging, z. B. in Kleinstopfmaschinen and the like, the alternate use left and right of a rail track results in large gravel displacements that preclude a precise Unterstopfung to create an abutment below the crossing rail / threshold. Two-shaft tamping units are now - according to DD-PS 209864 - the same Applicant in leveling equipment tamping machines with great advantage applicable, which for a stepwise feed in the machine longitudinal direction with simultaneous feed movement of the leveling tamping even an even higher performance, especially during processing high-speed tracks. In such a tamping machine targeted or trouble-free immersion of the individual stuffing tools of even greater importance to avoid interference or difficulty in any obstacles, due to the increased operating speed.

Object of the invention

The object of the invention is to form a track tamping machine with Steckstopfaggregat so that a much higher average power at higher compression can be achieved with improved adaptation to a variety of operating conditions.

Explanation of the essence of the invention

The invention has the object zugru rvde to create a track tamping machine of the type described above, the height adjustable Stopfagcj'egat for Unterstopfen two immediately adjacent thresholds by simple measures for submerging I eded a threshold is suitable, as well as improved conditions of use creates and with which where appropriate, a rapid change during the work from two to one-threshold clogging or vice versa is possible, with one; robust construction for absorbing the highest forces should be ensured. The object of the invention is now achieved with a track tamping machine described in a surprisingly simple manner that at least the au'Seren stuffing tools two in track transverse direction adjacent Stopfwerkzeugpaare the tamping unit each with their, ι the double tine supporting holder for disengaging the same - independently of the other Stopfwöirkzeugen -he height adjustable and are connected to a respective side adjustment drive. With this mashine a real universal machine is created, the two-shaft Streckenstopfaggregat has proven best in Einsa tz for processing two immediately adjacent sleepers in practice and only by up-adjusting the front or rear outer stuffing tools, without any hindrance can be converted into a sogeianntes Einschwellen tamping unit. This can be supported in a quick and easy way connecting points of distance a η Weichengleise or vice versa or even the end points in double thresholds of impact rails without any SETTING ligungsschwierigkeiten and disabilities in an advantageous manner. This Stopfaggregat training also has the advantage of simple and proven design, which also represents by the particularly close adjacent arrangement of the inner stuffing tools and this double-intervention in the stepwise processing of individual thresholds no obstacle. This immersion of the inner stuffing tools in the ballast at gradual work svorschub with simple threshold distance can be advantageously carried out only with provision of the outer, associated stuffing tools this Stopfwerkzeugpaares, in the other threshold compartment - in which the two inner Stopfwei dive tools - a further compression of the ballast against the subsurface is also achieved with simple threshold subsidence.

According to a further advantageous Mer kmalsanordnung according to the invention, the lower, supporting the double pickup holder of this stuffing tools for s eitlichen pivoting in a direction perpendicular to the supply direction of the stuffing tool level on a senkenkt to this plane eight extending axis and each with a trained for pivoting sides -Verstell drive connected. The structural design is particularly convenient and simple. Furthermore, this side-pivot training has already proven in tamping machines for the processing of points with single pimples in practice.

A particularly preferred Ausführun g η oh the invention is that only the rear in the working direction, stuffing tools of the Stopfaggregates with such, with their double pick adjustable height bracket for disengaging - regardless of al Jen other stuffing tools-height adjustable are formed. This training allows a particularly simple design of a stretch two-shaft tamping unit for conversion into a Einschwellen tamping unit. W 'eiterihin is by disengaging the adjustable rear outer

Stopping tools with gradual working feed with single threshold distance as a simple stretch stuffing machine created an improved Einschwellen tamping, since the threshold to be processed downstream sleeper compartment in addition to Beistell-loading also receives a further compaction against down or against the planum. A particularly useful embodiment of the invention is that both the Beistell drives for all eight stuffing tools with double pick and the common height adjustment drive for all Sopfwerkzeugpaare and the pivoting side adjustment drives formed by hydraulically acted piston-cylinder assemblies are and the common vibration drive is also designed as a hydraulic drive. Since in this drive training and the side-adjusting drives are designed as piston-cylinder assemblies, a further simplification with improved central control option is created by this measure overall.

Finally, according to a further feature of the invention, the hydraulic cylinder-piston Beistell drives, which are assigned to the inner, provided for dipping in the common threshold compartment and preferably associated with bent double tamping Stopfwerkzeugen - especially in stepwise feed of all six Doppelpickel and swung Doppelpickel with single threshold distance - blockable in the closest neighbor position. This measure has the particular advantage of using this Zwerschwellen tamping aggregate as Einschwellen tamping unit for larger distances, so that even greater uniform compression during underfilling can be achieved for these longer track distances.

A particularly preferred embodiment of the invention is that only the stuffing tools arranged on the outside with respect to the machine longitudinal direction of at least one pair of stuffing tools or only all externally arranged stuffing tools of the two adjacent in the track transverse direction and for dipping left and / or right of a rail in the Ballast bed provided stuffing tool pairs-regardless of the common Höhenverstellbarkeit- designed for disengaging or for retracting and extending and connected to an additional drive for a shift in height.

With a equipped with such a tamping tamping machine can now also advantageously areas where obstacles occur, for. As oblique thresholds, double sleepers in rail joints, but also partially in the way stationary track and the like, are supported without any adjustment difficulties and disabilities in a quick and easy way. The tamping unit according to the invention, which builds on a very well-proven in practice construction, has the further advantage that it is very easy to use both in progressively movable tamping machines - especially leveling, tamping and straightening without major design changes, but also for The latest track leveling, tamping and straightening machine designs can be installed, which are designed for a continuous work approach. In this case, / various advantageous ways of installation are possible - depending on the type of track or the conditions of use for which such a machine is provided either the height can be arranged additionally retractable and extendable tamping tools with respect to the working direction front or rear. Both variants have their advantages. A further significant advantage is achieved by the inventive construction in that at a threshold clogging by the inner stuffing tools, which may not be provided depending on the application, in the area of the emerging threshold compartment even with single threshold Ünterstopfung a stronger compression of the threshold compartment area is created. Machines with such invention designed tamping units also achieve a much higher average performance, since even with many or despite different obstacle areas, the track to be processed can be worked through quickly and easily. In addition, even over larger sections with such a two-shaft tamping unit single-threshold clogging with stronger compression - especially at junctions in the field of difficult track bodies are performed.

In the simplest embodiment according to the invention, it is possible for the adjacent in track transverse direction and for dipping left and right of a rail provided in the ballast tamping tools, and only for the front or rear outer stuffing tools with respect to a common, additional Provide drive for a shift in the height immediately adjacent or laterally of these tools. Even for such training, an improved adaptation to the different conditions of use is achieved compared to the conventional two-shaft tamping machines, with equally rapid conversion from two to one-threshold clogging or vice versa. In the context of the invention, the outer, in relation to the machine longitudinal direction front and rear stuffing tools for independent disengagement can also be connected in each case with such an additional drive for a shift in height, resulting in an optionally equipped in such a tamping machine Replaceability and even better adaptation to existing obstacle obstacles or to achieve diagonal thresholds or double sleepers. With such a design, however, advantageously only the inner stuffing tools of the two stuffing-tool pairs may also be used as what are known as spreading-stuffing-tool pairs.

Although such training requires twice the number of such additional drives for mutually independent 'height adjustment, regardless of the common height adjustment, but allows virtually a universal adjustability to almost all occurring conditions of use and thus greatly improves the performance of equipped with such two-shaft tamping units tamping machine.

According to a further, particularly advantageous feature of the invention, the dipping left and right of a rail provided in the ballast outer, preferably equipped with double tamping stuffing tools for independent immersion and independent retraction and extension are formed and connected independently acted upon height-displacement drives , This training in conjunction with the height shift drives allows even better adaptation, since with the independent, additionally height-adjustable tamping tools per rail side even the smallest irregularities or obstacle areas in prob ^: "loose manner can be considered Furthermore, this design is not significantly more space-consuming than with the conventional known two-shaft tamping machines, which is particularly important in constructing a wide variety of double-shaft tamping machines, since other tools must be arranged in a very compact construction directly next to these tamping units An advantageous feature of the invention is that the outer stuffing tools are provided with the additional, simple and constructively particularly expedient solution t

the ability to provide the design with simple hydraulic cylinder-piston assemblies, which are particularly suitable for rough operation in the processing of tracks. '

A particularly preferred embodiment according to the invention is that the height-adjustable or height-adjustable over the respective height-displacement drive stuffing tool in an approximately tubular and height-adjustable tool support frame pivotally mounted holder of the height is slidably mounted on which the Hydraulic cylinder-piston assembly formed height-displacement drive is fixed, wherein preferably the piston is in a fixed connection via a transverse connection with the upper end of the stuffing tool. Thus, the advantage is achieved that the holder itself serves for höhenverschiebbaren tools zurteleskopförmigen recording of the tool. Furthermore, a particularly resistant and robust construction is created by the tubular shaped support, in particular with regard to the large forces occurring during the plugging, such as penetration forces in crusted gravel and the like.

Other advantages are achieved in that the trained for receiving a stuffing tool and at least partially a double bead tubular holder is formed with mounting flanges for articulated mounting on the tool support frame and articulated connection with the associated hydraulic cylinder-piston Beistellantrieb, and that preferably at the opposite side, a further mounting flange for the arrangement of the hydraulic cylinder-piston Hörtenverschiebe drive is provided. This very simple in construction connection with the Stopfaggregat itself can be installed in a particularly advantageous manner in existing Stopfwerkzeugaggregat constructions without any additional modifications or the like. The two articulated points to which a conventional stuffing tool is articulated, thus serve simultaneously for the articulation of the tubular holder. A structurally simple and expedient solution is further achieved according to the invention, characterized in that the additional height-adjustable stuffing tool consists of two jointly in the tubular support height on bearing bushes slidably mounted single tools with preferably releasably mounted double picks, at the respective lower end of the stuffing plate is releasably secured, wherein both attached to the cross-connection of individual tools on the height-displacement drive up to the stuffing plates in the tubular holder telescopically formed and extendable. This very simple and practical solution results in a safe guidance and, moreover, the bearing points and the drive itself are protected from external influences by the tubular support reaching up to the picking plates (dust, stone chips, etc.).

According to a further feature of the invention, each outer, in addition to the height adjustable stuffing tool with a for holding or blocking the tool in the working or. Extended position trained retaining device connected. As a result, the advantage is achieved that the forces do not attack directly on the cross-connection and on the additional height-displacement drive, which also a construction with a relatively long life is created. In particular, but each game in conjunction with the additional possibility of movement of the input and Aususfahren, regardless of the general height adjustment, off, so that with such a construction even the highest forces, especially during immersion in encrusted ballast bed and the like can be taken trouble-free.

According to a particularly useful embodiment, the retaining device consists of a clamping tool in the working position clamped comprehensive and preferably formed by the provided with a longitudinal slot, tubular support clamping member with flanges attached to this, which preferably against each other via a hydraulic cylinder-piston assembly firmly clamped or are adjustable. This construction solution is not only simple in construction, but it creates a mechanical rigid connection between tubular holder and demtiöhenverschiebbaren stuffing tool by simple operation, which is'individually on the respective outer stuffing tools quickly manufacturable or solvable.

A particularly advantageous feature of the invention is that all in relation to the working direction outer outer, in particular with double pimple or equipped stuffing tools-both associated with a rail of the track tamping units a track construction machine-additionally adjustable height and each formed. connected to one, from each other and the common height adjustment of each Stopfaggregates independently acted, in particular designed as a hydraulic cylinder-piston assembly for remote control height-displacement drive. This arrangement has the advantage that - since only the front stuffing tools are designed to be vertically displaceable - the overall construction is simple and economical in construction - the rear outer stuffing tools are always extended during the immersion process, so that the thresholds can always be completely supported by the rear Stopfwerkzeugpaare and the once performed Unterstopfung is not changed. In obstacle areas in this case only the front outer stuffing tools are extended or retracted. Advantageously, in this arrangement, the inner stuffing tools with their respective Beistellantrieben continue to be acted upon or blocked, so that in a Beistellbewegung the inner stuffing tools of the front Stopfwerkzeugpaares and retracted front, outer stuffing tool through the inner stuffing tools virtually pre-compression of the front threshold he follows. This advantage also arises when only a threshold is supported over longer distances.

Finally, a further advantageous feature arrangement is according to the invention as ^r in that all ** γ equipped with respect to the working, "rect rear outer, in particular formed with Doppelpickef Ί tamping tools - both each eir rail of the track associated Stopfaggregate a track maintenance machine - in addition to the amount of adjustable trained and each with one, from each other and to the common height adjustment of each tamping unit indispensable gip acted upon, in particular designed as a hydraulic cylinder-piston assembly for remote control height-displacement drive are verbundän. In this arrangement, which is suitable for example for track tamping machines that can handle particularly heavy and retracted tracks with heavily crusted ballast bed in which the risk of displacement of an already-cushioned support is not given, the further advantage is achieved that the front, immovable , Outer stuffing tools always easier than single stuffing tools can penetrate into a heavily encrusted ballast bed than the rear stuffing tools, which indeed in the already processed gravel ^! plunge.

Fig. 12 and Fig. 14: a schematic plan view of the two tamping units, according to the embodiment shown in FIGS. 12 and 13 in another working position.

1 and 2, continuously moveable track leveling and straightening machine 1 has an elongated, at its ends via bogies 2 on one of rails 3 and e.g. Wood cross fins 4 existing track 5 supported chassis frame 6 on. On this a drive, power supply and control device 7 is arranged. For the advancement of the machine 1 in the direction of work represented by an arrow 8, a traction drive 9 is provided. At the two ends of the chassis frame 6 operating cabins are provided, wherein in the working direction rear main operator cab 10, a driving and control panel 11 is arranged, which is in communication with a central control device via control lines.

Between the by the elongated chassis frame 6 far apart bogies 2 a likewise elongate tool support frame 12 is provided. His back in Arbeitsrjchtung, located in part below the main operator's cab 10 end can be supported on the track 5 via a pair of support and Führungsradpaar 13. The front end portion of the tool support frame 12 is formed as a guide and connected via a variable length coupling device 14 for pivoting or tracking of the support and Führungsradpaares 13 with the chassis frame 6 and slidably mounted on this. The coupling device 14 is designed as a double-acting, hydraulic adjusting drive, the piston rod is pivotally connected to the dike-shaped tool-supporting frame 12.

For processing of sections, the machine 1 is arranged with one each on the tool support frame 12 and movable over each rail 3 in the direction of arrow 8, so-called two-shaft stretch tamping unit 15 for simultaneous Unterstopfen two immediately adjacent, for example, wood sleepers 4- fitted. The two tamping 15 upstream of a tool support frame 12 side and height adjustable connected lifting and straightening unit 16, whose tools for straightening and leveling the track 5 by, for example, as a wire reference line 17; 18 trained leveling and Richtbezugssysteme can be acted upon.

As can be better seen in FIGS. 4 and 5, each of the two-shaft section tamping units 15 shown only diagrammatically in FIGS. 1 and 2 for simultaneous underfilling of two immediately adjacent thresholds for both rail sides 19; 20 of the rail 3-two in the machine longitudinal direction according to arrow 8 arranged in succession Stopfwerkzeugpaare 21; 22 on. These consist of mutually adjustable and in the ballast bed 23 on both threshold longitudinal sides and on both rail sides 19; 20 submergible and vibrating tamping tools 24; 25; 26; 27, which are each equipped with double pick 28. The on the mutually facing sides of Stopfwerkzeugpaare 21; 22 located inner stuffing tools 25; 26, which are expediently equipped with cranked trained double pimples 29 are immersed in labor input in one and the same sleeper compartment 30 between two adjacent sleepers 4. All stuffing tool pairs 21; 22 on both rail sides 19; 20 with their hydraulic cylinder-piston assemblies formed Beistell drives 31; 32 connected tamping tools 24; 25; 26; 27 are arranged on the common tool support frame 12 and connected to a common, designed as a hydraulic cylinder-piston assembly height adjustment drive 33. With an equally hydraulically acted upon common vibration drive 34 thus each distance stuffing unit 15 per rail 3 forms a mechanical assembly.

As can be seen in Figures 1 and 2 and in detail in Figures 4 and 5, the outer stuffing tools 24; 27 of the two adjacent in the track transverse direction or on both rail sides 19; 20 arranged Stopfwerkzeugpaare 21; 22 of Stopfaggregates 15 each with their, the double pimples 28 supporting bracket 35 for disengaging bring the same height independently of the inner tamping tools-adjustable. For this purpose, each of the lower, the double tine 28 bearing bracket 35 of the outer stuffing tools 24; 27 for lateral pivoting in a supply direction of the stuffing tool substantially perpendicular plane mounted on a plane substantially perpendicular to this axis 36. For lateral pivoting, the holder 35 is connected in each case to an adjusting drive 37 designed as a hydraulic cylinder-piston arrangement, the piston of which is articulated in each case at the upper end region of the associated stuffing tool.

FIG. 6 shows the two-loop stretch-tying aggregate formed according to the invention for a better understanding in a partially schematic, diagrammatic representation. The Stopfaggregat 15 is in the raised position, d. H. the hinged to the tool support frame 12 height adjustment drive 33, which also as a hydraulic cylinder-piston assembly. ; is formed, is in the retracted position. The working in the direction of the machine 1 according to arrow 8, tamping unit 15 - corresponding to the position in Fig. 1 - has the two rear stuffing tools 27 with the associated Doppelpickeln 28 of the rear Stopfwerkzeugpaare 22 in the lateral position high or. swung. This lateral pivoting was effected by acting on the stuffing tools 27 associated with each adjustment drive 37 about the axis 36. The apparent in the drawing rear wooden sleepers 4 and the two joined to a joint wooden sleepers 4 have already been stuffed, in each case after gradual Arbeitsvorschub the 'stuffing unit 15 of all six, the respective Stopfwerkzeugen associated double pimples and the rear swung-up Doppelpickel 28- with single-threshold spacing. An arrow 38 indicates the incremental feed size from threshold tray to threshold tray. In Unterstopfung the two middle, directly adjacent wooden sleepers 4 in the region of the rail joint was an intermediate hydraulic cylinder-piston drive 39 with a spacer 40-as in the perspective view better recognizable-swung so that the rear stuffing tools 27 to the inner stuffing tools 25; 26 with their double pickles 29 have a large distance from each other to be able to dive with sufficient certainty on the long sides of the two wooden sleepers 4 in the respective sleeper compartment 30 in the gravel. It is also clear from this diagrammatic illustration that the penetration of the bent double pegs 29 on both rail sides 19120 of the rail 3 into the sleeper compartment 30 results in reinforcement due to the greater volume compared to a single double pimple 28 the compression against the ground is caused when penetrating into the ballast. With this inventively designed two-shaft stretch tamping unit 15 is thus turn off in the simplest way to a Einschwellen-stretch tamping unit. When not swung up double pick 28 this tamping unit 15 is the usual proven in practice two-shaft stretch tamping unit, as indicated in Fig. 3 schematically.

In FIG. 3, in the working direction of the arrow 8, the tamping unit 15, which can be adjusted in height on the common tool support frame 12, is shown movably on a track 42 with the support and guide wheel pair 13, whereby the respective intermediate sills 41 are also designated. The track 42 consists of rails 43 and concrete sleepers 44 resting on the ballast bed 45. The track leveling and leveling machine 1 with the two-shaft section tamping unit 15 shown in Figure 3 has not swung the outer stuffing tools 27 and is set to a stepwise feedrate with double threshold distance corresponding to the arrow 46. The schematically indicated dashed position of the tamping unit 15 shows the position for the next stuffing procedure, and that appropriate * as well with continuous right of way of the machine 1. During this continuous right of way of the machine 1, the tamping unit 15 on the in Fig. 1 as variable length and designed as a hydraulic cylinder-piston assembly coupling device 14 is held with the chassis frame 6 of the machine in the direction of movement. Of course, the machine 1 with the associated tamping units 15 per rail 3 are also used so that both the tamping units 15 and the machine 1 gradually work according to the respective feed size with single or double distance. This universal application without major changes or major design effort also creates the opportunity to take into account during the use of the respective track conditions in a quick and clear manner. Even with adaptation to any hindrances in the track or at relatively irregular, especially narrow threshold distances, the use of such a machine is associated with high efficiency. The two-shaft tamping unit 47 shown in FIGS. 7, 8 and 9, which will be described later in detail, is installed in the continuously movable track tamping, leveling and straightening machine 48 shown in FIGS. 10 and 11. This has an elongated, at its ends on bogies 49 on a chassis 50 consisting of rails 50 and sleepers 51, in particular concrete sleepers supported chassis frame 53. On this a drive, power supply and control device 54 is arranged. For the continuous feed of the machine 48 in the direction of operation represented by an arrow 55, a travel drive 56 is provided. In a rear direction in the working direction of the operator's cab 57, a driving and control panel 58 is arranged, which communicates with a central control device via control lines. -

Between the by the elongated chassis frame 53 - for a sufficiently large lifting or straightening movement-widely spaced bogies 49 a likewise very elongated tool frame 59 is provided. Its rear end in the working direction can be supported via a pair of support and guide wheels 60 on the track 52. The front end portion of this tool frame 59 is formed as a guide and for pivoting or tracking of the support and '·. ·'

Führungsradpaares 60 connected via a double-acting hydraulic adjustment 61 with the chassis frame 53 and slidably mounted on this. The size of the variable length, the chassis frame 53 and tool frame 59 hinged hydraulic adjustment 61 has an adjustment that is about twice the feed size for each Unterstopfungsart (Einschwellen- or two-shaft clogging), in the present embodiment therefore about four times a threshold distance. The machine 48 is, as better seen in the plan view of FIG. 11, each equipped with a movable over each rail 50, so-called two-shaft tamping unit 47 for simultaneous submergence of two immediately adjacent thresholds 51. The two Stopfaggregaten 47 is associated with a tool frame 59 side and height adjustable connected lifting and straightening unit 62, whose tools for straightening and leveling the track 52 via leveling and straightening reference systems, for example via a wire leveling reference 63 are acted upon.

As can be better seen in FIGS. 7 and 8, each of the two-shaft tamping units 47, shown only diagrammatically in FIGS. 10 and 11, for the simultaneous stuffing of two immediately adjacent sleepers 51 respectively comprises two pairs of plugging tools 66 arranged one behind the other in the machine longitudinal direction according to arrow 55; 67 on. These consist of hydraulic cylinder-piston actuators 68; 69; 70; 71 adjustable against each other and in the ballast bed 72 on both sides of the emerging threshold and-as can be seen in Figure 11-on both rail sides 64; 65 submersible and via a common vibration drive 73 vibratable Stopfwerkzeugen 74; 75; 76; 77. These stuffing tools 74; 75; 76; 77 are each, in particular for processing on routes, with double pimples 79; 80; 81; 82 equipped. The directly on the tool frame 59 successively arranged Stopfwerkzeugpaare 66; 67 each of the two

Two-shaft tamping units 47 are guided at this height adjustable and connected to a common hydraulic cylinder-piston height adjustment drive 78. The on the mutually facing sides of Stopfwerkzeugpaare 66; 67 located inner tools 75; 76 have with their cranked, respective double-headed pegs 80; 81 each have a fork-shaped shape and are immersed in the labor input in one and the same threshold compartment 83 between the two adjacent sleepers 51. Each two-shaft stuffing unit 47 thus forms with old Stopfwerkzeugpaaren 66; 67 and their Beistellantrieben and their common vibration and height adjustment a mechanical assembly. The arranged according to FIG. 7,8 and 9 with respect to the machine longitudinal direction on the outside, front stuffing tools 77 each Zweischwelien Stopfaggregates 47 of the two adjacent in the track transverse direction and for dipping left or right of the respective rail 50 provided in the ballast bed 72 Stopfwerkzeugpaare 66 are - regardless of the common height adjustment-disengaging or for independent retraction and extension of the height formed and each connected to an additional drive 84 for a shift in height. These two height-shifting drives 84 are likewise formed by a hydraulic cylinder-piston arrangement and can be acted upon independently of one another. These outer, additionally height-adjustable Stopfwerkzeuge 77 are formed for retracting and extending telescopically and each mounted in an approximately tubular and on a height-adjustable tool support frame 85 pivotally mounted bracket 86 of height slidably. The front, additionally height-displaceable, outer stuffing tools 77 are each made of two together in the tubular support 86 of height over bearing bushes 87 slidably mounted single tools 88 with preferably releasably secured. Doppelpickel 82 formed, wherein both in a cross-connection 89 mounted individual tools 88 via the height-displacement drive 84 to the actual stuffing plates 90 in the tubular support 86 telescopically formed extendable and retractable-see in particular Fig. 9.

The tubular holder 86 formed at least partially with its double pick 82 up to the respective stuffing plate 90 for receiving the additionally height-adjustable stuffing tool 77 or the two individual tools 88 is furthermore provided with mounting flanges 91 for articulated mounting on the tool support frame 85 and articulated connection with the associated hydraulic Cylinder-piston Beistellantrieb 69 provided, wherein on the opposite side, a further mounting flange 92 is provided for the arrangement of the hydraulic cylinder-piston height-displacement drive 84. The piston 93 of this drive 84 is in this case firmly connected via the cross-connection 89 with the upper end of the stuffing tool 77.

As can be seen in more detail in particular from FIGS. 7 and 9, each outer front, additionally height-adjustable stuffing tool 77 is connected to a holding device 94 designed to hold or block the two individual tools 88 in the working or extended position. The retaining device 94 consists of one, the two individual tools 88 in the working position clamped comprehensive and provided by the longitudinal slot 95, tubular support 86 formed clamping member 96 and attached thereto flanges 97, which via a hydraulic cylinder-piston assembly 98th are mutually clamped or adjustable. The piston rod of the associated, attached to one of the two flanges 97 cylinder of the hydraulic cylinder-piston assembly 98 passes through the other flange 97 and has at its end an abutment 99. When pressurized, the two flanges 97 'are pressed together, whereby the tubular holder 86 in the region of the longitudinal slot 95, the two individual tools 88 clamped with their bearing bushes 87. The retracted tamping tool 77 located on the rail side 65 is inserted with its individual tool 88-as can be seen in section in FIG. 7-together with its associated double tine 82 in the tubular holder as far as the tamping plate-as well as in the plan view according to FIG. lower part, recognizable on average. Therefore, located on the other side 64 of the rail 50 front individual tools 88 are clamped with its bearing bush 87 by its associated and pressurized retaining means 94 in the tubular support 86, wherein the abutment 99 for the hydraulic cylinder-piston assembly 98th the clamping of the two flanges 97 causes the tubular support. In Fig. 7 are further on the left side in dotted outline, the cross sections of various forms of sleepers 51, z. As concrete or wooden sleepers or higher special sleepers, recognizable. All these different thresholds 51 result in the Unterstopfung with respect to the Einsteilung, Beistellung and in conjunction with the very often different, in particular too narrow threshold distance these difficulties that can be largely avoided with the inventively designed two-shaft tamping 47.

As can be seen in particular in the schematic plan view of FIG. 11 on the two tamping units 47 of the continuously movable track tamping, leveling and straightening machine 48, all with respect to the working direction outer and with double tamp 82 trained stuffing tools 77 both in each case a rail 50 of Rail 52 associated Stopfwerkzeugpaare 66 each in a tubular support 86 in addition the height adjustable or: formed accordingly. These stuffing tools 77 are therefore each connected to a separate, from each other and the common height adjustment 78 each Stopfaggregates 47 acted upon and designed as a hydraulic cylinder-piston assembly for remote control, immediately adjacent to or side of this stuffing tools 77 arranged side height shift drive 84 is connected ,

In Fig. 10 and 11 is further particularly well seen that in the region of the sloping threshold 51 -des Stopf shown in Figure 1 below tamping 47-the front outer stuffing tools are moved upwards, d. H. they are in retracted position. With such a stuffing tamping unit 47, this machine 48 in continuous right of way in the direction of arrow 55 perform both a two-shaft tamping and a Einschwellen-Unterstopfung. In the case of swelling-in-relief, there is the advantage over conventional swelling-type stuffing machines that the inner stuffing tools result in increased compression of the sleeper compartment, in addition to the threshold choking. The conversion from on-shaft tamping to clogging is especially important in such continuously variable tamping machines, where it is important to achieve a trouble-free working cycle even more quickly and without difficulty, since the actual tamping work with the progressively advancing tamping unit 47 is according to a two- or three-stroke tamping unit Einschwellen feed according to the arrows 100; 101 must take place during the continuous passage of the machine 48.

Another exemplary embodiment of a tamping leveling and straightening machine 103 equipped with tamping units 102 according to the invention and designed for stepwise operation or working in the direction of the arrow 104 is shown in FIGS. 12, 13 and 14. This machine 103 also has an elongated end at the ends on bogie trolleys 105 on one off

Rails 106 and wooden sleepers 107 existing track 108 supported chassis frame 109 on. On this is a *

Drive, power and control device 110, a travel drive 111 is arranged for the progressive advancement of the machine 103 in the working direction represented by the arrow 104. In an operating cab 112 provided in the working direction at the rear, a drive and control console 113 is provided, which communicates with a central control device via control lines and the like.

Between the elongated chassis frame 109-for a sufficiently large lifting or directional movement-far apart bogies 105-to form a so-called compact machine-are, as in the plan view of FIG. 13 also better recognizable, the two-shaft Stopfaggregate 102 arranged. Each tamping unit 102 assigned to each rail 106 is designed to submerge two immediately adjacent sleepers 107. The two Stopfaggregaten 102 is associated with a chassis frame 109 side and height adjustable lifting and straightening unit 114, whose tools for straightening and leveling the track 108 leveling and straightening systems, such as the illustrated wire leveling reference chord 115, can be acted upon , Each Stopfaggregat 102 has in the machine longitudinal direction immediately adjacent Stopf tool pairs 116; 117, with over hydraulic cylinder-piston auxiliary drives 118; 119; 120; 121 act on and provided in particular with double pick stuffing tools 122; 123; 124; 125. In this two-shaft tamping machine 103, the arrow 104 disposed on the outside with respect to the machine longitudinal direction is the tamping tool pair 122 adjacent to the track transverse direction and for dipping left or right of the rail 106 into the ballast bed with an additional hydraulic cylinder piston Elevator drive 126 connected. Each tamping unit 102 is connected to a common height adjustment drive 127 and a common vibration drive 128. Each of these two two-shaft tamping units 102 installed in the step-by-step ancestor two-shaft tamping machine 103 is thus practically identical to the tamping unit 47 shown in FIGS. 7-9 and likewise has respective retaining devices 129 for the outer rear tamping tools 122. to hold these stuffing tools sufficiently in the * working position. The two Stopfaggregate 102 are offset only with respect to the outside arranged Stopfwerkzeuge with respect to the working direction by 180 °-compared to the exemplary embodiment according to Figs.7-11.

The two-shaft track tamping machine 103 is shown in a working position with lowered tamping unit 102, in which the already processed track section respectively by the two adjacent tuft tool pairs 116; 117 was processed and with which, however, the track 108 is processed with the apparent in Fig. 12 and 13 double wooden sleepers 130 according to the arrows 131 by Einschwellen-Unterstopfung-for example, in a track arrangement in which then the threshold distances are even narrower. This training or arrangement of tamping 102 according to the invention gemfiß the illustrated two-shaft tamping machine 103 with only rear, in addition to the height and extendable tamping tools 122 is not only simple in design, but it also achieves the following advantage - the front, only with the common height adjustment 127 height-adjustable stuffing tools 125 are always immersed in the gravel, wodu is ensured raw that these single-stuffing 125 can penetrate easily in a hard, crusted ballast bed 132 with certainty, since very often the Eindringwideretand such tracks very is high. The inner stuffing tools 123; 124, however, then dip, for example, in Einschwellen-Unterstopfung already in the loosened from the previous operation ballast bed 132, so that this training or arrangement is suitable for such two-shaft tamping machines 103 especially for filtered tracks for processing, which have a hard or encrusted ballast bed , ,

14 shows a very schematic plan view of the two two-shaft tamping units 102 when used on a track body 133 with branching track. The rear stuffing tools 122 both left and right of the rail track

134 plunger tool pairs 117 which can be submerged in the ballast bed are in a raised position or in a retracted position, whereas the rear, retractable and retractable stuffing tools 122 of the other two-shaft tamping unit 102 of the rail track are:

135 together with the other stuffing tools 123; 124; 125 are in submerged condition.

It is thus possible for the first time to work with the same machine, for example at the first working passage with a one-threshold Unterstopfungszyklus and for example in the return journey with a two-shaft Unterstopfungszyklus or vice versa with such, trained or equipped two-shaft Göpfopfmaschinen 48 and 103 or - as shown by the example gemfiß Rg. 12 and 13 shown-also with the same two-shaft tamping machine 103 sections to process different track sections in the same operation. Such changes can be made quickly and safely by the operator's cab 57; 112 via the driving and control console 58; 113 are controlled.
