Device for fixing the ends of two used for leveling the track Reference line

It is well known that young people learn to be at the level of the track level Time preferably used facilities where two above the Jlöises running parallel to its target position Reference straight lines are provided. Each of these reference lines is assigned and permitted to a rail track there is a measuring and monitoring device attached to the leveling machine, the difference to be eliminated between Make the target and actual position of the track visible; the track or the individual track is then as long as increased until this difference becomes zero. The reference lines are created by tension wires or by bundles of waves, e.g. bundled infrared rays embodied. In principle, the height correction is sufficient to level the track one of the two rails; the other track can be deo C-leises with the help of the locally known transverse slope be brought into its target position. For better control of the transverse slope, however, it is advantageous to have two lengthways 3 to use a straight reference line and to monitor the correctness of the transverse tilt; mg additionally.

The device according to the invention can be used for both methods and is its most essential feature characterized in that the organs used to fix the reference line, z.3. Jraht - lalter, sender or receiver, on the crossbeam of an in one on the track resting rigid frame perpendicular to the track axis versc-hv; @nlcbaren Pendulum are arranged.

According to a preferred further feature of the invention, the crossbar Id is its angular position to the axis of the

Adjustable pendulum.

In the straight track, where the bank should be equal to Hull, the ones on the crossbeam will be Fixation organs due to the action of the pendulum running perpendicular to the crossbeam always fötlg into the Adjust horizontal. On the other hand, however, it is more unfamiliar r possible, the cross baik in a certain Sührägstellung to bring to the pendulum axis if - in track curves - a certain cant of the track is to be established.

The inclination of the crossbeam is due to The effect of the pendulum is completely independent of the respective inclination of the pendulum carrier resting on the track iand is used exclusively in a specific relationship; to the stand absolutely horizontally. This is important in that Yes mainly the front ones, im not yet corrected iTrack area located ends of the reference line will be fixed; the pendulum carrier designed as a vehicle therefore cannot embody a reliable basis for maintaining the correct cross slope.

According to a further feature of the invention, the organs used to fix the reference line are attached to the the two arms of the crossbar are arranged to be adjustable in height; this is the distance between the reference line and the upper edge of the rail can be regulated in principle, regardless of the desired transverse inclination of the track.

Further features of the invention, in particular the structural details of two examples described Embodiments are shown schematically in the drawings: FIGS. 1 and 2 each show such an embodiment in a front elevation.

According to FIG. 1, the pendulum 3 is mounted in one on a chassis 1 with wheels 2 serving as a pendulum carrier Joint 4. This pendulum 3 is in one to the axis of the 5 rails and cross sleepers 6 existing rails can be pivoted in a vertical plane and can be fixed in an angular position connectable with a crossbar 7.

around this <^ - aer »baiken 7 in a certain angular

To bring a position in relation to the pendulum 3 is a self |

on the pendulum articulated with a supporting member 8 supporting actuating | screw 9 is provided, which is guided in a nut Io connected to the crossbeam 7. To connect the To always ensure support organ 8 with the pendulum 3, a tension spring 11 is provided that the pendulum 3 against the Eating support member 8 presses. Vibration dampers 12 provide a Keep the pendulum still 3.

The pendulum 3 is also equipped with an indicator that is with the pendulum swing along a Scale 14 of the chassis frame 1 moves.

The organs used to fix the straight lines are located at the two ends of the crossbar 7 and consist in the illustrated embodiment of two height-adjustable guide rollers I5 for tension wires 16; Of course, it is sufficient to use a tension wire 16 common to both rails 5 on both rollers 15, which then - as can be seen in the illustration, crosses the track behind the rollers 15.

Adjusting screws I7 with handwheels 18 are used to adjust the height of the guide rollers; the extent of the height, adjustment can be read on scales 19.

Display elements 2o can also display the position of the cross bar 7 in relation to a rigid cross part 21 of the chassis 1. ^f ''

The mode of operation of this device according to FIG. 1 is as follows:

If a straight track is leveled whose superelevation (transverse slope) is naturally zero, then the crossbar 7 is brought into a position that is absolutely perpendicular to the pendulum 3 and is fixed. Through this the pendulum 3 automatically ensures an always absolutely horizontal course of the crossbar 7 and the same height Fixing members 15 for the tension wires 16, provided that they were previously set in the correct height position.

If a certain elevation of the crossbar 7 is to be set, this elevation is set by pivoting of the pendulum 3 on the scale 14 with the display

organ 13 and then, by means of the adjusting screw 9, ensures that the crossbar 7 is level and is fixed in this position to the pendulum 3. Since the pendulum itself is in one of the verticals by the value of the elevation during this adjustment If it was held in a different position, it will - as soon as it is released - always try to keep the crossbar 7 in a position deviating from the horizontal by the value of the cant, i.e. in an inclined position corresponding to the desired cant lie than the right one, then the pendulum 3 must first be pivoted to the right; ¹ In this position of the pendulum 3 pivoted to the right out of the vertical, the crossbar is then fixed horizontally on the basis of the display elements 2o and transverse

- -balken 7 the pendulum is released, it inevitably holds the crossbeam in a downward sloping incline to the right

'Position, i.e. in a position in which the left leadership role 15 is higher.

. { The device '' according to FIG. 2 is similar in its mode of operation.

Ί Here, too, a pendulum 3 is mounted in a joint 4 on the 1 / chassis 1, which is equipped with wheels 2

-i'iiat in such a way in a plane perpendicular to the track axis ^ pivotable.

Only the adjusting device for changing the angle between the pendulum 3 and the transverse beam 7 is different. It consists of a linkage 22, which on the one hand on the crossbar 7 in of joints 23, on the other hand through Pivoting a along a setting scale 24 pivotable display member 25 is adjustable. A handle 26 is used to fix this setting, the display organ 25 is pivotably mounted in the joint 27 on the pendulum 3 and in turn carries joints 28 for the linkage 22.

The fixation organs for the reference blocks can be like in the embodiment of FIG. 1 - from guide rollers

exist, which by means of adjusting screws 17 and handwheels * 8 are arranged vertically adjustable on the crossbar 7.

It goes without saying that they are within the scope of the invention numerous other design variants are conceivable. As Already mentioned, · do not necessarily have to ^ two reference lines to be used; a 3rd straight line is sufficient:, where then an to place an inclinometer on the leveling machine is; which enables the second rail track in Dependent on the other strand in the correct altitude bring to.
