The invention relates to a device for progressively aligning a track in terms of height, a track lifter and a bank inclinometer arranged in the area of the track lifter, as well as a Has switching element, which, influenced by the inclinometer, the activity of the track lifter controls automatically so that the track has a predetermined transverse inclination when the lift is finished.

In a known device of this type, for example, the inclinometer has a pendulum on, on a frame that can be moved on both rail tracks and is equipped with a track lifter is pivotably mounted and when a predeterminable, adjustable transverse inclination is reached, an electrical one The contact closes and the lift of the track lifter ends automatically.

In the course of the so-called elevation ramp of a track curve, i.e. in the transition area between the straight track that is not elevated and the one with a curve that corresponds to the radius of the curve If the track of the arch is superelevated, the cross slope of the track changes gradually, as is well known between the value zero of the straight track and the respective cant for the track curve. The previously known devices require an ongoing adjustment of the increase ramps locally required constantly changing bank slope. The operating effort for Carrying out this constant adjustment is not inconsiderable, apart from the fact that in this activity It is only too easy for errors to occur that cause an incorrect track position.

The invention is based on the object of this constant change in the transverse slope of the track to be carried out automatically. According to the invention, this object is achieved in a device of the type mentioned at the beginning mentioned type solved in that the switching element still a second, in the already aligned Is assigned to the track area bank inclinometer and the switching element is designed in such a way is that the necessary control pulses for the track lifter by comparing the track slope can be obtained in the already aligned track area with the track transverse slope at the track jack.

This device does not require any operating effort in the cant ramps of track curves and automatically ensures that in the train As the bank changes, the correct new bank measure will gradually be achieved at the end of the ramp is reached flawlessly.

Preferably, the two inclinometers with the switching element are each device for progressive alignment via an electrical line
of a track of height flat

connected and each have the voltage in the «5 assigned line according to the respective Bank changing organ on. In addition, there is an arbitrarily adjustable one in one of the two lines Arranged rheostat and the switching element designed so that it responds as soon as in both lines have the same voltage.

Each of the inclinometers expediently has a voltage divider that can be adjusted by a pendulum or rheostat.

In the drawing, an embodiment of the invention is shown, namely shows

F i g. 1 in a schematic bottom view of a device for aligning a track in terms of height, FIG. 2 is a side view of this device,
F i g. 3 and 4 an inclinometer for different track layers and

F i g. 5 shows a schematic representation of the mutual assignment of the two inclinometers and the switching element of a device according to the invention.

The chassis 1 shown in Figs The track tamping machine runs on the two rails 2 and 2 'of the track, which are on the sleepers 3 and rest indirectly on the gravel bed 4. With 5 tamping tools of the track tamping machine are designated, which can be of any conventional type. At the front of the track tamping machine track jacks 6 are arranged, and immediate

bar in the area of one of these track jacks 6 is a height-movable independent of the chassis 1, Measuring rod rolling on rail 2. 7, the upper end of which with a reference line serving tension wire 8 cooperates. This tension wire 8 extends from a front anchorage 9 to a tension roller 10 arranged above the front axle of the chassis 1 and embodied a parallel to the desired target position of the track.

The mode of operation of such a device is known in principle and is based on the fact that, for the time being, the Rail 2 is raised by the associated track lifter 6 until the leveling rod 7 touches the tension wire 8 touches and such the achievement of the correct height (target position) of this rail 2 indicates. the Activity of the track lifter 6 assigned to this rail 2 is carried out when the tension wire is touched the measuring stick 7 - preferably automatically - ended. The correct height of the second rail 2 'leaves can be achieved by lifting while monitoring the cross slope, as described in the setup the invention, the transverse slope in the already corrected track section, for example in the area of The front axle of the track tamping machine is used as the basis.

There is therefore an inclinometer in the area of this front axle and a measuring stick in the area 7 and the track lifter 6 a second inclinometer is arranged. In their collaboration show this roll inclination when the cross slope at the location of the track jack 6 with that in the already corrected track section matches or differs from it by a certain amount.

The inclinometer can according to FIGS. 3 and 4 be formed. In these figures, that of the upper edges of the two rails 2 and 2 'designated transverse inclination plane of the track with 11. An articulated frame 12 is assigned to this level 11, the upper connection of which is the Bearings of a pendulum 13. The pivoting of the pendulum 13 affects a dental arch 14 and any gear train an organ, which the voltage in the leading to a switching organ Line changes according to the respective transverse slope, e.g. a voltage divider 15. In Fig. 3 the inclinometer is shown above a horizontal track in the transverse direction, whereas in Fig.4 the track has a slight transverse slope which is indicated by a deflection of the pendulum 13.

As now the F i g. 5 can be seen to find two inclinometers in the device according to the invention Use, the frame 12 or 12 'resting on track levels 11 or 1Γ and pendulum 13 or 13 'with dental arches 14 or 14' and voltage dividers 15 or 15 'or the like and via lines 16 and 16 'are connected to the switching element 17.

This switching element 17 is designed so that it is connected to the control of the track lifter 6 for the rail 2 ' Serving line 18 emits an electrical pulse as soon as the voltage in the two lines 16 and 16 'is the same, i.e. that is, as soon as the transverse slopes of planes 1 and 11 'are equal to one another. This electrical impulse therefore terminates the activity of the track lifter 6 of the rail 2 'as soon as the correct one Cross slope has been reached at the point of the track to be corrected.

As already mentioned, at the beginning and end of elevated track curves, the bank must already be corrected track area from the cross slope at the point of the track to be corrected on the ramp section differ by a certain constant amount. Such a deliberate predetermined difference to be able to adjust, a variable resistor 19 is provided in the line 16, with the help of which in In such cases of a difference in slope, automatic control of the track lifting activity is guaranteed is.

Should the cross slope in the already corrected track section prove to be incorrect in some cases and thus do not offer a correct basis for the transverse slope at the point of the track to be corrected, so an elimination of this error is also with

ao the help of the rheostat 19 possible at any time.
