Die Erfindung»betrifft eine Einrichtung zum selbst- bar ist, daß die Lichtquelle in die Bezugsebene hintätigen Steuern einer Gleisrichtmaschine, die ein sich einbewegt wird.The invention relates to a device that allows the light source to move back into the reference plane Controlling a track straightening machine that is being moved in.

Die Einrichtung kann aber auch so ausgebildetreference system extending in the longitudinal direction of the track - the light source is preferably in the reach of which comprises a light source, a slit diaphragm and straightening tool of the straightening machine on the track to a photoelectric receiver, which is arranged at 5 so that it directs the directional movement of the track with a non-rectilinear alignment of the light source, power. The error signal from the receiver then controls the slit diaphragm and the receiver controls an error signal.
is pending. However, the device can also be designed in this way

Es sind drei verschiedene Arten von aus diesen io sein, daß die Lichtquelle mit dem vorderen, mittels Teilen bestehenden Steuereinrichtungen bekannt. Bei einer Stellvorrichtung senkrecht zum Gleis verstellder ersten Art werden die drei Teile (Lichtquelle, baren Ende einer Meßbasis verbunden ist, die ihrer-Blende und Empfänger), die konstante Abstände seits zum Steuern des Richtwerkzeuges dient, wobei voneinander aufweisen, zusnmmen mit der Rieht- das Fehlersignal des Empfängers die Stellvorrichtung maschine vorwäfisbewegt. Diese Einrichtung gestattet 15 derart steuert, daß die Lichtquelle in die Bezugsoffenbar kein Ausrichten des Gleises gemäß einem ebene bewegt wird. Dadurch wird die Einrichtung gewünschten Profil, weil der vordere Endpunkt auch bei größeren Abweichungen des Gleises von der (Lichtquelle) der Bezugsgeraden sich entsprechend Sollage brauchbar.There are three different types of from these io be that the light source with the front, means Known parts of existing control devices. With an adjusting device perpendicular to the track adjusters The first type are the three parts (light source, baren end of a measuring base, which is connected to its aperture and receiver), the constant distances are used to control the straightening tool, with have from each other, together with the direction- the error signal of the receiver the adjusting device machine moved forward. This device allows 15 controls so that the light source in the reference is revealed no alignment of the track according to a plane is moved. This will set up the facility desired profile, because the front end point even with larger deviations of the track from the (Light source) of the reference straight line can be used according to the nominal position.

Infolgedessen 5° Anheben des Gleises dient eine Gleiszange 10, die wird die Richtarbeit erheblich verlangsamt. mit einem hydraulischen Zylinder 7 verbunden ist.In a third known device, with machine 2, which runs on the track 3 to be straightened, the straightening machine only advances the screen that the front carriage 1 carries a receiver with provided at the location of the straightening tools. The light-set slit diaphragm for displaying the reference source is further forward on a level that has been found to be good. The tamping and leveling machine 2 has set up the point of the track still to be straightened and has a light source and a track lifting device.
the receiver is firmly set up further back at a point on this machine 2, from the track, which has already been set up for the sake of simplicity. This one only the front part is shown, there is a direction should guarantee the greatest precision, since 45 vertically displaceable rods 4, which are fixed at both their lower end points of the reference straight line. You er end a feeler roller 5 and at the upper end one requires that the part that carries the rear end point of the light source 6. The feeler roller 5 runs on a defined, independent of the straightening machine on the rail 3, so that the light source 6 is always mounted in a separate carriage that maintains a separately prescribed height above the rail. To push and must be adjusted. As a result, 5 ° lifting of the track is used a track clamp 10, which slows down the straightening work considerably. is connected to a hydraulic cylinder 7.

As long as the two photocells and each other are not exposed to the same intensity via a control device to be described, the track itself is lifted by means of a roller at point A on the active until the light source 6 reaches the level 15 is supported on the track.

For simultaneous leveling and alignment of the receiver and the slit diaphragm on the housing 14, two independent control devices can be used at a perfect point on the track. However, it is even more advantageous if the front carriage 1 is provided. So the track becomes a single panel with two perpendicular to each other according to the desired professional!
