The invention relates to a method for the progressive alignment of tracks in the track direction, especially curved tracks, measured by means of wandering tendons guided on the track, whose arrow heights are measured and are used to determine the standard.

In a previously known method of this type for compensating for directional errors within a The track section bounded by a chord is first an arrow height of the actual position of the track measured in relation to this chord, then from this arrow height the arrow height to a second, shorter, calculated within the segment cut by the first tendon and afterwards the track is moved sideways at the point to be aligned until the calculated arrow height with corresponds to their actually measured size.

With this method, the actual course of the track is used in the area that has not yet been corrected Considered to the extent that this course is covered by the anterior end point of the longer tendon will. For practical reasons, however, the length of this longer tendon cannot be chosen to be too great because the tendon or the like usually has to be embodied by a wire. With the previously known Processes therefore have an effect caused by errors in relation to the target course of the track incorrect position of the anterior end point of the longer tendon is relatively strong, and there is only a limited possibility of compensating for such errors. It was mostly because of that necessary to apply the procedure several times in succession to a track to be aligned in order to achieve a to achieve a sufficiently even track course.

The invention is based on the object of developing a method in which further than before and with better success in the not yet corrected track area can be "felt" and with the Pay more attention than before to the actual course of the track in the not yet located track area can be taken without localized inaccuracy and errors in this actual track course can falsify the result of this "anticipation". The advantage achieved by the invention consists mainly in the fact that this mostly leads to a multiple repetition of the compensation procedure can be dispensed with, because a better balance of the track position is achieved from the outset.

The object on which the invention is based is achieved according to the invention in that by means of a first chord which is arranged in the working direction in front of the straightening point and runs entirely in the as yet unaligned track area, an arrow height of the method for the progressive alignment of tracks in the track direction, in particular track curves, as well as equipment to carry out

The actual position of the track is measured and the track is moved at the alignment point until one second tendon, the center of which is at the point of alignment, an arrow height is reached, the size of which is in such a linear relationship to the size of the measured in the as yet unaligned track area Actual arrow height and the arrow height of one moving from the straightening point into the already aligned track area extending third chord stands that the difference between the arrow height of the third and first chord to the difference between the arrow height of the second and the first chord in the same ratio stands like the distance between the corresponding measuring points of the third and first chord to the distance between the measuring points of the second and first tendons.

According to a preferred embodiment of this method, the three tendons used are the same long, which makes the implementation of the method and the equipment used for this essential can be made simpler. The distance between the arrow height measuring point is expediently first tendon and the straightening point the full length of a tendon.

Consideration of the actual situation of the not yet carried out, as shown in FIG. 4 schematically

directed track curve area are completed: is shown.

As the F i g. 3, the value 65 is illustrated.The rectilinear potentiometers 1, 2 and 3 (each at C by shifting the track in the measuring, for example with 100 ohm resistance) are initially changed at point B and the next in front a power source 4, e.g. a 12- Volt battery, at point at which the actual position of the track curve is determined, closed and located with a measuring device 7, the

indicates whether the required arrow height ratio is present in a common circuit.

The potentiometers 1, 2 and 3 are adjusted according to the arrow heights measured at the measuring points A, B and D respectively. The circuit also contains resistors 5 and 6, of which resistor 6 is twice as strong as resistor 5.

If zero cannot be read on the measuring device 7, this measuring device 7 indicates the direction in which the height of the arrow at measuring point B must be changed; compensation is achieved as soon as the measuring device 7 points to zero. A change in the height of the arrow at measuring point B is possible by means of the method shown in FIG. 5 to bring about the device shown.

This movable device according to FIG. 5, which can be moved in the direction of the arrow, comprises six four-wheeled carriages which are numbered 8 to 13 and by means of couplings each half a chord length together are connected. Each carriage is held against one of the two rails 15 or 16 by springs 14 pressed against the rail 15 in the device shown.

Three rectilinear potentiometers 1, 2 and 3 are used as devices for measuring the height of the arrows on the Carriages 9, 10 and 12 are stored. These three potentiometers 1, 2 and 3 are connected to an electrical circuit, as shown in FIG. 4, connected.

There are three rigid rods of equal length that embody the tendons 17, 18 and 19. The tendon 17 is embodied by a rod articulated on the carriage 8 at one end, which extends over the carriage 9 and is articulated on the carriage 10 at the other end. The articulated mounting on the carriage 10 should also enable the rod to move lengthways. This will make any slight change in the distance of the cars 8 and 10 when driving compensated by curved track. In the middle of the rod embodying the tendon 17 the local Arrow height by means of an element arranged on the rod and displaceable with respect to the potentiometer 1 measured; this organ can be displaceable in relation to the potentiometer in the manner of a piston.

The rods embodying the tendons 18 and 19 are alike on the carriages 9 and 11 and 11 and 13, respectively arranged, and the potentiometers 2 and 3 are assigned to them in the same way.

The straightening machine 20 is located between the downstream carriage 10 and the upstream one Car 11 and is connected to either one or both of these cars by means of tie rods or the like. so that the straightener can move the entire facility in any direction. The straightener 20 is equipped with devices at both ends to turn the track sideways to the right or to be able to move left.

Now if the facility is on a curved track or a poorly aligned straight Track is located, the cars 8 to 13 will follow the left track 15, and the sliding ones Organs of the potentiometer 1, 2 and 3 are each shifted by exactly one distance that the Corresponds to the heights of the arrows at the measuring points. By means of a circuit as shown in FIG is, the measuring device 7, which is to be placed in front of the operator of the straightening machine 20, will display, in which direction the track is to be moved on the carriage 10, and the operator then has just operate the straightening tools until the measuring device 7 shows zero.

The minimum distance between the points where the track is to be moved can best be determined from the Practical experience can be determined. If the device has the forward gear to be aligned Track section has ended, then it can - if a particularly high degree of accuracy is required - it will be necessary to set up for one of the control of the track system and for repeated Retrofit corrective reverse gear. For this purpose, the potentiometers 1 and 3 are in the electrical Circuit switched over. The potentiometer 2 is moved from the carriage 10 to the carriage 11 brought, but remains in its position in the electrical circuit. The rigid tendon 18 is of the Carriage 9 to 11 brought to the carriage 10 to 12, and the straightening machine 20 moves the track in Area of carriage 11.
