The aim of the invention is to improve the accuracy of the local track correction improve without, however, causing a significant increase in the expenditure of time and a reduction in the route performance. Of the The time required is of course decisively influenced by the accuracy, care and speed with which the track is lifted or shifted sideways and is monitored; on the other hand, however the accuracy of the control of the track lifting process or the sideways displacement of the track is reduced to the same extent that the effort of care and the speed is increased.

According to the most essential feature of the invention, the problem with a rapid implementation of the track movement to achieve an exact track position, solved by the fact that a control! -, display and / or signal device is provided to be corrected at the Position of the track the activity of the track correction tools in combination * act with the reference system both for a coarse correction to be ended before the target track position is reached, as well as for a during to control the fine correction taking place during the last phase of the corrective movement of the rail.

It is characteristic of the invention that the entire process the track movement required to correct the track position from the actual position into a target position is divided into at least two phases, and

to be sure, in a first, more quickly feasible, the rough correction is used Phase and into a second, immediately following, more slowly to be carried out phase, which is used for fine correction and with particular accuracy can be carried out and completed.

According to a preferred embodiment of the invention, control elements are accordingly provided which, by means of a monitoring device, allow a first phase to be carried out more quickly to be followed by a second phase to be carried out more slowly in the entire track movement.

That Gewtaitunf to control r, Aasige- and / or signaling device, which is benutst for controlling the termination of the first phase and of the beginning of the second phase of the invention extremely numerous compliments are in the context often.

For example, a device according to the invention consists of at least one reference straight line and at least one feeler element which cooperates with this reference straight line and which are combined to form a monitoring device. In this case, it is relatively easy to provide control organs for the timely termination of the first phase of the track movement before the respective target position of the track is reached, which control elements respond depending on a certain position of a feeler element cooperating with the reference straight line in relation to the reference straight line. The training of the control organs can be very varied.

-5-The sleepers of the track are marked 5.

The machine is in the area between the two trolleys 3 and located side straightening point with the side straightening tools 6 and with laterally outside the sleeper heads on the ballast bed top attachable bedding compaction tools 7, which can be designed as surface compactors, on both sides of the track separately adjustable in height and depending on one or the other Side are arranged to be operable. The actuation or lowering of these lateral bed compactors only takes place on the side from which the track is withdrawn in order to be shifted sideways into the target position; in this way, these bedding compactors are able to move the To effectively support the track on the opposite side of the track and to reliably prevent the track from springing back.

The machine also has the chassis frame on the front side a height-adjustable unit 8 for lifting the track with a couple of rail grippers 9, which can be designed as rolling grippers, for each rail track.

Bedding compaction tools 10 * are also assigned to this lifting device 8, which are mounted in the usual manner on a height-adjustable carrier in the front part of the chassis frame 1 in pairs opposite each other

To level the track by means of the lifting device 8, 9 is at least a reference straight line 17 parallel to the nominal position of the track is provided, e.g. a bundle of waves emanating from a transmitter (or receiver) 18 and Via a measuring and monitoring device 19 to a receiver (or transmitter) 20 runs.

The transmitter 18 located in the not yet corrected track area is located as a front station on the front carriage 13, which can also be used as the end point of the long chord 11. The measuring and monitoring element 19 is at rest indirectly on the rail line to be corrected and can be moved upwards together with it in order to act as a diaphragm when the target position is reached immigrate into the wave bundle or the like embodying the reference straight line 17, thereby creating the connection between transmitter 18 and receiver 20 to interrupt and thus generate a control pulse. The receiver 20 is also directly on the chassis 21 via a chassis track 4 to be corrected.

In Figs. 3 and 3a a device is shown only as an embodiment, which lead to a (premature, namely before reaching the target position of the track to be carried out completion of the first phase of the track correction, namely the lifting of the track by means of the track lifting tools 8, can then be used to complete the last lifting phase, marked with the dimension χ, with the same tools, but more slowly and to be able to carry out this more precisely.

These Figs. 3 and 3a show the measuring and monitoring device, namely the probe member 19 from FIG. 1 cooperating with the reference straight line 17, on a larger scale. This probe member 19 is accordingly from a fixed part 22, which has a rod or not shown the like rests on the track 4 gradually migrating up as a result of the activity of the track lifting tools 8 and thus in the Correction of the track in the direction of the arrow gradually moves up towards the reference straight line 17. At this fixed part 22 is a with a tactile edge for the reference line 17 provided movable part 23 guided displaceably in the direction of movement of the feeler member 19 and can be adjusted by an adjustable Dimension χ be shifted beyond the tactile edge of the fixed part 22, lh the upwardly displaced end position comes in the direction of movement of the upward moving probe member 19 first the probe edge of the movable Part 23 with the reference line 17 in contact; the movable part 23 can then be in an inoperative position, ie under the tactile edge of the fixed part 22 are shifted back to such the touch edge to enable this fixed part 22 to interact with the reference straight line 17 when the measuring element 19 continues to move upward.

To adjust the movable part 23 is a pressure medium drive consisting of the piston 24 and the cylinder 25, for. B. a hydraulic or pneumatic drive.

109829/0079

In a similar way - also by means of a pressure medium drive Height of the feeler edge of a feeler element 19 * according to that shown in FIG and 4a shown embodiment can be adjusted. This feeler member 19 'is laterally adjustable by means of a pressure medium drive 24 * and 25' and has two tactile edges of different heights by the dimension χ. By shifting the feeler element sideways to the right, the lower feeler edge can be adjusted below the reference straight line 17 after the higher tactile edge in cooperation with the reference straight line 17 to terminate triggered the impulse serving the first phase of uplift. The second phase of lifting can then be started when the track has reached the desired height can be ended by touching the lower tactile edge with the reference straight line 17.

As FIG. 5 shows, the pressure medium control of this piston-cylinder drive 24, 25 according to FIGS. 3 and 3a is included in the pressure medium system used to actuate the track lifting tools 8. First of all , the movable part 23 of the feeler element 19 is in the upper position ( FIGS. 3 and 5); In this phase , the piston-cylinder drive of the lifting device 8 is supplied to the full extent (with full capacity) of pressure medium via the valve 28. In this first phase, the track is raised quickly and roughly until the touching edge of the movable part 23 of the feeler element 19 touches the reference line 17.

109829/0079

The generated impulse arrives (via lines not shown) to the receiver E, from this to an amplifier V and from this Amplifier V to the control device S. This control device S adjusts the valve 28 in such a way that by means of the from the container B the pressure medium flowing in, on the one hand, is the piston-cylinder drive 24 and 25 of the adjustable part 23 of the feeler element 19 moves this adjustable part 23 into the lower, inoperative position, on the other hand the same pulse and the same position of the valve 28 also causes the piston-cylinder drive 8 of the lifting device via the throttle valve 29 is only fed with lower pressure; the uplift is slowed down and can be carried out and monitored more precisely.

As the above-described embodiments show, it is possible in the framework of the invention to distance the feeler element 19 from the reference straight line 17 for the implementation of the second phase of the correction process in that the feeler element 19 or a straight line 17 with the reference cooperating part 23 of the feeler element is adjusted.

It is, however, on the other hand also possible ^ ugsgeraden the reference line 17 and that part of such a Be, with which it cooperates, the feeler member 19 to the extent χ temporarily and partially to adjust, thereby the second for tripping, the correction operation definitively i to gain the necessary dis'a ^ ation between the feeler element and the reference straight.

A structural variant of such a device is shown in FIG. The reference line 17 is embodied here by a tension wire guided over tensioning rollers 30. Pivotably mounted, lever-like organs are able to press from above onto the pan wire embodying the reference line 17. If only one such lever-like organ 31 is arranged on only one side (on the right in the drawing), the straight line 17 receives the Verlaitf 17a (shown in dashed lines) due to the action of this organ Reference straight line the dash-dotted line ar interpreted lead 17b, if both organs 31 are pivoted at the same time: *.

In both cases, the reference line 1 is then located in the area of the feeler element 19 (at least approximately) by the illustrated dimension χ closer to the feeler element. The first contact of the feeler member 19 with this Be.-Zugsgeraden 17 causes the lever 31 to pivot back; the reference straight line 17 then runs again by the dimension χ from the measuring element 19 at a distance y indicating the desired position of the track, shown in full, parallel to the track (FIG. 3a).

The movable, pivotable members 31 are adjusted by means of hydraulic or pneumatic drives 32 against the pressure of return springs 33 and is triggered by the contact with the feeler element , 19 with the reference straight line 17 triggered first pulse.

Of course, the tensioning rollers can also be used within the scope of the invention 30 itself can be height-adjustable and adjusted in two different positions in the direction of advance of the feeler element indicated by the arrow, namely in a closer to the feeler member 19 and a further distant position to after a first touch of the feeler member 19 in the desired Distancing to get the measure χ.

The feeler member 19 does not need in the context of the invention as Be formed tactile edge, diaphragm or the like, but it can also consist of a target board, a receiver, a transmitter or the like.

The measures according to the invention are equally applicable to the side straightening of tracks and a device suitable for this with the associated control is shown in FIG. Along a spindle 36 is a traveling nut 37 as a display organ transversely to Slidably mounted track axis. This display member 37 carries a Fork 38, which encompasses the tendon embodying the reference line 12 on both sides. By means of contacts arranged on both sides of the tendon J.2 Fork 38 can be determined and signaled when the adjustable display element 37 is in a position corresponding to the position of the tendon 12 is located on the spindle 36, in which the tendon 12 touches neither one nor the other of the two fork contacts and is free of contact the fork 38 extends.

109829/0079 C 3567

By means of a pressure medium actuated drive, consisting of
a cylinder 39, a piston 40, a piston rod 41 and a Bückholfeder 42, the slidable with respect to the hiking nut 37 guided fork 38 is initially adjusted by the amount χ of the tendon 12 closer, so that the contacts arranged on the fork when aligning the
Track by means of the side straightening tools 6 emit an impulse before the actual target position of the track occurs; On the basis of this first impulse, the activity of the side straightening tools is slowed down so that it can then be monitored more precisely in the second phase of the side straightening movement.

Show other possibilities available within the scope of the invention
8 to 13. These representations are intended to explain that it is possible to work with several reference straight lines 17 and 17 'with which the measuring element 19 (or several feeler elements) can be used one after the other
Get cooperation. Such reference straight lines 17, 17 * can be arranged one behind the other (FIGS. 9, 10 and 11) and / or next to one another (FIGS. 10, 11 and 13) in the direction of movement of the feeler element 19. Are the reference lines in the same direction as the direction of movement of the
Probe member 19 vertical plane, then the probe edges of the probe member are to be offset from one another by the dimension χ (Fig. 13).

1784H7

Are the reference straight lines 17, 17 * both in different vertical planes and in different horizontal planes and have also the feeler member 19 offset against each other in the direction of movement Edge, then the dimension χ results as a function of the difference • y of the position of the reference straight line 17, 17 * on the one hand and from the difference ζ the position of the feeler edges of the feeler member 19 on the other hand; for example, in the case shown in FIG. 11, the dimension χ results from the function χ = y - ζ.

In the embodiment according to FIGS. 8 to 13, both reference lines 17, 17 * embodied by rays of light that run between two transmitters (or receivers) 18, 18 * and two receivers (or transmitters) 20, 20 *.

Such reference lines can also be embodied in the same device by different types of media. Example, in the variant according to FIG. 14, the upper, shown in dashed reference line 17 by a via tension rollers 30 guided tension wire, the lower reference line 17 * on the other hand by a between the transmitter 18 and receiver 20 extending light beam verkörper ¹ The measuring member 19 is a bezel that When the track moves upwards as a result of lifting, the light beam 17 * is first interrupted in order to trigger the first pulse, and then together with the tension wire, the second pulse is triggered. In this case too, an arrangement of the reference straight lines 17, 17 * analogous to the arrangement according to FIG. 11 is possible. 109829/0079

It is also possible, according to FIGS. 18, 19, to use different types of reference line 17 'to combine it side by side and one with staggered tactile edge formed aperture 19 to use, analogous to Fig.

All variants according to FIGS. 8 to 19 are otherwise the same Can be used both for side straightening the track and for leveling the track.

The subject matter of the invention is also largely the same in all other details modifiable and expandable.
