Description

The invention relates to a mobile tamping machine with a machine frame supported on trolleys and one around a vertical axis parallel to the track level laterally pivoted tool frame, as well with juxtaposed in the cross-track direction and independent of one another via drives adjustable tamping units, which are provided via drives and vibrating tamping tool pairs with in the gravel have immersible tamping picks.

A known mobile track tamping machine - according to DE-OS 17 59 833 by the same applicant or patent owner - with the features described above, has two tamping tool carriers arranged on such a laterally pivotable and freely projecting tool frame arranged for simultaneous tamping Two adjacent sleepers each carry two tamping units arranged one behind the other in the longitudinal direction of the track together with the correction device. Each tamping unit comprises height over drives and tool pairs beistell- each other and vibratable tamping - pickeln with gravel in the left and right of one or the other rail immersible stuffing - on. The two supports are on the machine frame for machine frame about a vertical axis ver pivotable ver with independent drives independently of each other. This track tamping machine with this compact design, which is common in older machines, with a projecting arrangement of the tamping units on the machine frame or on the side-pivoting tool carrier, is also particularly suitable for tucking track switches and the like. trained with the independently swiveling individual tamping tools and a reference system as a leveling tamping machine.

Another known track tamping machine - according to AT-PS 2 97 775 - of the older compact design has a cantilever arrangement of the tamping units on a tool frame which can be pivoted sideways to the machine frame with an independent, cross-displaceable arrangement of a total of two height-adjustable tamping units assigned to a rail on. These are mounted on the tool frame, which is cantilevered over the foremost machine chassis and laterally pivotable via drives about a vertical axis of rotation to the machine frame and is elongated and adjustable in a transverse displacement path, where the tamping tools change better due to the change to adjust the rail spacing in switches. This version is structurally complex, since the laterally pivotable tool frame extends back over the entire machine frame and is fastened or supported there by a slide bearing for the pivoting movement. In addition, there is the disadvantage of an inaccurate centering possibility of the jointly swiveling tamping tools above the threshold to be tamped because the axis of rotation of the tool frame is arranged at a distance from the center of the transverse sliding track. In particular, there is the disadvantage caused by this distance arrangement that such an imprecise adjustment means that the tamping tools do not come to lie parallel to an inclined threshold and that an accurate and permanent tamping cannot be carried out.

Another mobile track tamping machine - according to DE-OS 34 24 683 by the same applicant or patent holder - is designed as a track tamping, leveling and straightening machine of the so-called compact design. These machines have proven themselves over the last 20 years compared to the machines with the cantilever design described, since the arrangement of the tamping units and the track lifting / straightening unit between the widely spaced undercarriages corrects a much more accurate elevation and lateral track position is feasible, which additionally results in a gentle bending line of the rails due to the relatively wide chassis distance to avoid an inadmissible bending stress. In this track tamping machine is provided for each rail track, with its one end via a length-adjustable coupling device articulated on the machine frame arranged tool frame, each with a tamping, lifting and straightening unit, each with a laterally pivotable tool frame at its other end opposite the Ge steering point has a single supporting and guiding undercarriage designed for driving on a rail as a free steering undercarriage. The tamping, lifting and straightening units are so-called switch units with areas for processing for switch points and the like. equipped sideways swiveling tamping tools or lifting tongs and straightening track rollers.

It is - according to DE-OS 34 24 667 by the same applicant or patent holder - a track tamping machine with one Stuffing unit of modern design known, consisting of two each Weil assigned to a rail and via drives from mutually independently cross-adjustable tamping units with two rails on the left and one on the right, respectively Ren darning tool pairs is formed. To create Each tamping tool has its own tamping unit  Pair of independently height adjustable training det, so that even in difficult switch sections a track obstacle in the area of a rail side Opposite tamping unit for one hindered tamping can be lowered.

Furthermore, according to GB-OS 2 01 178 A - a track pot machine of the cantilever type known, the four over own drives independently of one another vertically and transversely has adjustable tamping units. For the track position correction on this machine with cantilever construction no lifting and straightening units are provided. Such adjustable darning units are - as in the DE-OS 20 23 964 and in particular in the preamble of the Proof 1 of DE-OS 30 26 883 described - each assigned in pairs to a rail, with all four un height-adjustable stuffing units depending on each other with their own drives independently on one guide frame arrangement provided on the machine frame voltage are designed to be displaceable. With this be known arrangement of a total of four from each other depending on the height and transverse adjustable tamping unit units with a pair of tamping tools for thawing Chen left or right of one or the other rail is another area in track switch sections workable, but especially when irregular ß Threshold distances or with inclined smoldering len the very high demands on the accuracy of the Track position correction not satisfactory are.

The object of the invention is to drive a bare track tamping machine of the type described in the introduction to create, especially in difficult track areas, e.g. in switch sections or also in tracks sloping thresholds or with often different  Chen threshold distances can be used and with which a quick, easy and accurate adjustment of the darning tools for dipping into the ballast is aimable.

This object is achieved with a mobile Gleisstopfma machine of the type described above according to the invention that a total of four in Gleisquerrich device arranged side by side and each independently adjustable in height via their drives tamping unit units - each with a tamping tool pair with the left or right of one or another rail immersible tamping pick - at least the two external tamping unit units with their height adjustment drives for transverse adjustment are each mounted on a swivel tool frame that can be pivoted laterally independently via a separate drive about a vertical axis to the machine frame .

With this surprisingly simple and constructive yet very robust new basic construction are individual, independently adjustable plug aggregate units in relation to their arrangement and their independent adjustment to constructively simple, however solved very useful type, the special, by the arrangement of these four single tamping unit units achievable benefits of continuous machining too Maintain difficult switch sections and with regard Lich the threshold adjustment can still be improved. With the special, swiveling bearing at least least of the outer tamping unit units to each its own swivel tool frame is mechanical highly resilient and structurally simple connection to the Machine frame manufactured, being by each own tool frame and cross swivel drive Independence of the individual tamping unit units  from each other for a targeted and individual Adjustment to the respective track obstacles still ver is strengthened. By training at least the two outer tamping unit for one independent pendent side pivoting becomes an advantageous one rapid and unimpeded adjustment or centering of the Darning tools for tamping the already located in the branch track and through the common Long sleepers still tied to the main track support of a switch section. With the This solution is also a particularly on the part of Operator particularly well observed and controlled bare overall arrangement of the tamping unit units both in the centering process as well as for the immersion and case setting process created. A particularly constructive one Simplification is also that for this very advantageous side pivoting of the outer tamping unit gat units none far beyond the clearance profile protruding cross guide connected to the machine frame tion with appropriate storage is required. By are attached to a swivel tool frame the two external tamping unit units easily and swivel back in quickly within the clearance profile bar.

There is a particularly advantageous training of the invention in that the two external tamping unit units each because at the end of their swivel tool frame Are trained, each of these elongated training swivel tool frame in the outer tamping unit Unit adjacent area on a horizontal Additional slide or guideway of the machine frame is supported. This elongated and such cantilevered design of the swivel tool frame creates a relatively large total lateral ver setting range of the assigned tamping unit for  a hassle-free, simple, trouble-free joint Main and branch track tamping, whereby by the support of each swivel tool frame on the Slid and guideway safe in every swivel position re support of the tamping unit unit guaranteed is. Due to the end arrangement of the tamping unit Units on the swivel tool frame is special advantageously the one opposite the articulation End area with every external tamping unit for a quick and precise centering or observation of the respective darning tool pair to a large extent easily visible. This should be stuffed into the the switch sections with the different tracks conditions, such as handlebars, switch rods and the like. Like. from of particular importance since the operator at the difficult areas with the highest concentration tion works to prevent damage to the track avoid.

A very useful and advantageous training after the invention is that each of the two in Working direction free in front of a chassis cantilevered and elongated swivel Tool frame with its external tamping unit each about one above the other Rail vertical axis, from the respective Inner tamping unit off, can be swung out to the side is arranged. With this cantilevered and long straight design of the two swivel tool frames men are the external tamping unit units in one right relatively wide total swivel range especially for a simple and trouble-free stuffing from next to it areas on the track, in particular branches tracks, side adjustable. The formation of two axes for the swivel tool frame allows one fold training and storage without mutual interference Influence.  

According to an advantageous development of the invention are the two between the outer tamping unit-in internal tamping unit units their height adjustment drives on the machine frame or attached to a tool carrier connected to this arranges. This from the outside tamping unit un dependent arrangement of the two inner tamping units units has the advantage that those for the cramming the far outer track sections, in particular the branch tracks, provided external tamping unit Units in the simplest way from the inside stuffing aggregate units independently in a very wide ver adjustment range including the swivel tool frame are adjustable or centerable. The interior The tamping unit units remain unchanged as before Partially usable in the track area. The Arrangement on the machine frame or on your own Tool frame can advantageously be independent of the external tamping unit depending on the machine type for processing turnouts and / or routes con structurally accordingly. The below has different arrangement of the tamping unit units also the advantage that their weight load on two different sections of the machine frame is divided.

A very advantageous and convenient training of Invention is that the two, in the field between the two swivel tool frames or outer Tamping unit units on the machine frame or tool Carrier arranged inner tamping unit with their height adjustment drives each via transverse guidance and a separate drive for the machine frame are designed to be slidable in relation to one another. With this storage of the internal tamping unit these are both from each other and from the two  External tamping unit units for one ent speaking rapid and precise adjustment or center cross obstacles in the simplest way adjustable. The cross guides are themselves for a very wide transverse adjustment range without problems half of the clearance profile and without disturbing influences solution connected to a swivel tool frame to arrange an external tamping unit. Through the se different storage of the outside and inside stuffing Unit units is advantageously also one Relief of the cross-guides by the rapid Immersion process of the tamping ax in the gravel relatively high resistance can be achieved.

A particularly preferred development of the invention is that the tool carrier with the two independently height-adjustable inner tamping unit units, preferably together with the transverse guides and the two transverse displacement drives via its own drive by one - in which by Stuffer aggregate units leading transverse vertical plane and through the machine longitudinal axis - vertical axis parallel to the track plane is rotatably mounted on the machine frame. This rotatable mounting of the tool holder has the particular advantage that the two inner tamping unit units are still rotatable about a vertical axis while maintaining their independent transverse displaceability. In this way, the tamping pick of the inner tamping unit units can be aligned parallel to inclined sleepers in an advantageous manner and at the same time can also be centered by means of a corresponding transverse displacement exactly above the point to be tamped, with only a slight additional design effort. The axis of the track more distant, in particular also to the side track reaching areas are on the other hand with the outer tamping unit units - v.area by pivoting of the pivotal tool frame to the respective threshold or rail position - processed. As a result, even the most difficult switch sections with a variety of different track obstacles, in particular in the form of switch tongues, can be tamped or corrected quickly with constant tamp quality. In addition, this special arrangement of the inner tamping unit units without its own swivel tool frame enables an essentially independent or unimpeded or simpler arrangement of the two swivel tool frames connected to the outer tamping unit units.

An advantageous training of the invention also exists in that each side-swiveling outer tamping unit gat unit and the associated internal tamping unit Unity on the opposite sides of the track cantilevered and on the mutually facing Pages essentially flush and in relation to each because of the plane of symmetry of the mirror are pictorially trained. This special asymmetry cal training advantageously allows a immediately adjacent - very close - arrangement of each because an outer and an inner tamping unit for a particularly advantageous observation by the Operator and for an unimpeded and disruptive uninterrupted tamping of an intersection set rail / threshold.

According to a particularly practical and advantageous design according to the invention, each of the two is connected to an external tamping unit and is preferably cranked parallel to the track level or has a wedge-shaped swivel tool frame from its vertical axis to the respective external tamping unit gat unit at least about 4 to 5 m or about the size of two to three and a half times the track width long and preferably via its respective drive for a total pivoting path of the respective tamping unit unit of about 1.7 m. Due to this particularly elongated design of the two swivel tool frames, the relatively wide total swivel path of the external tamping unit units can be achieved without technical difficulties, in particular with a solid support on the machine frame. Au ßerdem is thereby a favorable support within the machine frame in an advantageous way - un ter BEITEN avoiding time and labor consuming Umrüstar - sufficient. A maximum adjustment or swivel angle range can be achieved for each tool frame, in particular even with more inclined sleepers.

According to a particularly preferred Aus education is the vertical axis of every swivel tool Frame in the working direction behind the central axis the immediately the outside and inside tamping unit-on following chassis or behind the preferably trained as a bogie and immediately the central drive adjacent to the tamping unit of an articulated machine frame orderly. This training enables advantageous Way a particularly stable support of the swivel Tool frame on the central chassis, where as Bogie the weight of the tool frame and stuffing aggregate units is divided on two axes. Dar moreover is due to the flexible training of the Ma machine frame a shift of the driving cabin from with suspension for a completely unobstructed arrangement and training the two swivel tool frames and of the assigned drives possible.  

A very advantageous development of the invention is that the two external tamping units with their height adjustment drives each in the vertical axis opposite end region of the swivel tool frame rotatably mounted around a further vertical axis and for pivoting against the track axis or against the respective internal tamping unit to be connected to one drive each. This two-fold articulation of the swivel tool frame allows a very extensive adaptation to switch sections which are also difficult to stuff without restricting the advantages mentioned at the beginning of an independent pivoting of the outer tamping unit units. With the help of the second vertical axis, regardless of the lateral position of the outer tamping unit unit that can be achieved by the first vertical axis, for precise centering over the sleeper support to be tamped, an exact alignment of the tamping pick in a sloping long sleeper pa in the longitudinal direction parallel position can be carried out in the simplest way. Thus - in connection with the inner tamping unit - also such inclined sleepers, which are therefore more difficult to tamp, especially in connection with various track obstacles, can be tamped faster, more precisely and more evenly. It is advantageous that this double articulation of the swivel tool frame requires only a small additional constructive effort.

According to a further feature of the invention, each elongated swivel tool frame is arranged projecting from its vertical axis in the working direction and with its free end region - preferably directly to the slide or guideway - with the outer tamping unit gel kig connected. The arrangement of the external tamping unit units in the free end area of the projecting pivoting tool frame has the advantage that for the operator a better and essentially unimpeded view or control of the external tamping unit units for their rapid and accurate centering, especially above the turnout section lying outside the track. The arrangement of the slide or guideway directly next to the tamping unit units also ensures that the tamping unit units are supported in a particularly so lid manner while relieving the load on the swivel tool frame.

A particularly advantageous development of the invention is characterized in that each of the two elongated swivel tool frames is made in several parts, in particular in the frame longitudinal direction telescopically extendable and with its own drive - for longitudinal adjustment of the outer tamping unit mounted on the tool frame end Unit - is connected. This ver extensible design of the swivel tool frame allows light in the simplest possible way an independent longitudinal displacement of each external tamping unit for its exact centering or adjustment over a different threshold distance or in particular inclined threshold. With the teleskopförmi gene training a simple change in length of the tool frame with essentially the same stability is feasible.

According to an advantageous development of the invention is furthermore each of the two elongated and with the swivel unit connected to the external tamping unit Tool frame as preferred in the longitudinal direction of the frame telescopically extendable and verti in cross section Kal-running beam with in the upper beam area arranged hydraulic drives trained. These  Training the swivel tool frame as a vertical Beam has the advantage of high bending stiffness, whereby by the arrangement of the hydraulic drives in upper beam area a mutual disruptive one flow of the two swivel tool frames avoided becomes.

A particularly advantageous and practical fiction according training is that the two with the swivel unit connected to the external tamping unit Tool frames with their vertical axes, their ver actuators and adjustment areas and the two Internal tamping unit with its adjustable connection driven mirror image in relation to the longitudinal axis of the machine Lich trained to each other. With such a mirror image arrangement will not just be one partial rapid and clear usability of the Tamping unit units, but also largely even load distribution on the machine frame achieved. It is also one for both machines along the same work area, in particular the two external tamping unit units guaranteed.

A particularly advantageous embodiment of the invention is characterized in that the two laterally and parallel to the track level with their respective swivel tool frame swivel or twist outer tamping unit together with the preferably tamper-evident or twistable inner tamping unit -Units - to form a track leveling, tamping and straightening machine in a compact design - immediately in the working direction behind a track lifting and straightening unit provided on the machine frame and designed for use in switch areas and together with this between two widely spaced, especially as Bogies trained bogies are arranged. This advantageous arrangement of the outer and inner tamping unit units and the track lifting and straightening unit between the widely spaced bogies enables high efficient un tamping even difficult track areas with precise track position while avoiding an impermissibly high bending stress on the rails. In addition, the end carriages limit the track section to be corrected for an exact lateral and vertical position.

According to a preferred development of the invention the two with their respective swivel tool frames men can be swung out sideways independently of each other External tamping unit and the two of each other the independently transverse and preferably also ge jointly rotatable inner tamping unit one the track lifting and straightening unit in the working direction orderly and for optional editing of the left or right siding section can be used or additional Lich laterally pivotable lifting device assigned. With the specially for the tamping of branch glue sen. Like. provided, laterally swiveling Au External tamping unit units in connection with this additional lifting device is a precise lifting of the switch section over its entire cross cutting area achievable so that the outside are also the switch sections through these side-pivoting External tamping unit units of the same quality are stuffable. In addition there is also a discharge of the machine's own track lifting and straightening unit enough.

Finally, according to an advantageous fiction the two outer and two inner Tamping unit units one of the two slewing works  tool frame and the tool carrier in the working direction upstream and in the field of vision of the track lifting and Straightening unit and the additional lifting device arranged operator's cab with a counter to the ar seat and operator console assigned. By this arrangement are those by which mutually independent cross adjustment option individually to be centered outside and inside tamping unit ten in connection with a safe track lifting better and more precise thanks to the track lifting straightening unit visible or controllable, which makes a total higher efficiency when using such a trained machine is achievable.

In the following the invention will be described with reference to Drawing illustrated embodiment closer described.

As soon as the branch track 37 is reached in the course of the gradual work approach, the threshold is both stopped in the area of the two rails 5 and 6 of the main track 7 and in the area of the two switch tongues or rails 35, 36 of the branch track 37 . For this purpose, the external tamping unit 17 after tamping the threshold in the outer region of the rail 5 of the main track 7 with the drive 23 together with the associated pivoting tool frame 27 into the position shown in full lines in FIG. 2 panned. Simultaneously with a pivoting, the Stopfaggre gat unit 17 is rotated about the vertical axis 62 by actuating the drive 65 , as a result of which the darning ax 38 , 39 is aligned parallel to the longitudinal axis of the sloping threshold 4 in this section of the switch. The opposite external tamping unit 14 is adapted in the same way by corresponding actuation of the drive 64 to the inclined de threshold. The tamping pick 38 , 39 of the inner tamping unit 15 , 16 is adjusted by correspondingly rotating the tool carrier 28 about the vertical axis 41 with the aid of the two drives 40 (see in particular FIG. 5). With a corresponding loading of the two drives 47 , 48 , the two unit frames 45 , 46 are then pushed transversely until the inner tamping unit units 15 , 16 come to rest over the area of the rail 6 and 35 to be tamped . At the same time, there is a positive connection of the additional lifting device 32 to the branch track 37 by the lifting rollers 51 being brought into engagement with the rail 36 . Before carrying out the tamping, the track 7 together with the branch track 37 is raised by actuating the height adjustment and straightening drives of the track lifting and straightening unit 31 and the drive 54 of the lifting device 32 (see three arrows in FIG. 3) and using the straightening and leveling reference system 13 brought into the correct target position. At the same time, it follows a lowering of the previously tamping tool pairs 18 to 21 centered above the tamping area to understop the raised switch section. This is followed by a short transverse adjustment of the outer tamping unit 17 while maintaining the track elevation unchanged until the associated tamping pick 38 , 39 come to rest on the opposite side of the rail (see the tamping pick indicated with weaker points in FIG. 5). Likewise, by appropriately transversely displacing the inner tamping unit 16 along the transverse guides 42 , the sleeper support area located between the inner switch tongue and the rail 5 is tamped. After all four tamping unit units 14 to 17 have been raised, the machine 1 continues to travel to the next threshold 4 , where the described tamping process begins anew in the same manner.
