The invention relates to a device for aligning a track laterally and vertically with a straightening device that grips the track by means of a motorized rail gripper and so on raises and moves far until the track is the correct one in relation to a reference base that defines the target position Has taken position, and which is in the working direction in front of the tamping tools of a cooperating with her, is located on the already aligned part of the track moving track tamping machine.

In the case of such previously known devices, support rams have hitherto been in the area of the straightening device intended to use the ballast bed as an abutment when straightening the track. This However, the ballast bed is not able to provide a really reliable basis for an exact correction of the track position to embody, especially not when this gravel bed is simultaneous with the correction is compacted by means of vibrating tamping tools in the same area and if so, then also the support punch vibrate along with the whole facility. The ballast gravel loaded by the support rams will then tend to migrate sideways and cannot absorb the compressive forces that occur when the track is lifted, any more than the lateral forces occurring when the track is straightened.

The invention is therefore based on the object of providing a device of the type mentioned at the beginning create that when aligning the track of a support on the ballast bed by means of support stamps not required.

The solution to this problem is that the straightening device in a front side of the front axle the track tamping machine over the cantilevered part of the chassis frame to be corrected the track tamping machine is arranged and the rail gripper both the side and can be moved in height by motor.

With such a device, the alignment of the track height and side to the chassis frame of the machine can be carried out much more precisely and without interference, especially because the front axle of the chassis frame immediately adjacent to the track area to be corrected presses and prevents the already corrected track that its position changes undesirably as a result of the movement of the track at the adjacent correction point. The extent of the required displacement of the track of the side and the height can be the device for aligning a track

therefore especially with the grippers that can be moved by motor, both laterally and vertically precisely control, for example a specific, previously determined measured value can be perfectly controlled retain.

According to a further feature of the invention, the means carrying the rail grippers can be in one Motorized, height-adjustable guide can be moved laterally by motor. This embodiment makes it possible to use a common height adjustment device with a common drive for both the provide rail grippers assigned to both rails.

The invention is illustrated in exemplary embodiments with reference to the drawings. And explained, whereby

to tamp individual sleepers 3 by means of the tamping tool assembly 4 of the usual design and to fix them in the new position. A cantilevered on the front end of the chassis frame 1 part 5 carries the various organs for aligning the track of the side and the height. These organs include, inter alia, a cylinder that can be acted upon by pressure medium and is denoted by 6. For example, an approximately T-shaped feeler element 7, which interacts with the tension wire 8 embodying the reference line, can be used to monitor the degree of elevation. Of course, many different types of monitoring organs are also technically applicable, such. B. when the reference line od instead of a wire by a directional beam. The like. Is embodied. The wire 8 can, for. B. be anchored at one end to the machine itself. If its other end is anchored in a stationary manner, the machine carries a tensioning roller 9 which gradually takes up the wire as the machine moves forward while the tension is always constant. Rail grippers 10, which are provided with rollers 10 'in the area of the top of the rail head, serve to move the track 2 sideways and also to lift it. To move this rail gripper 10 transversely, a cylinder is provided in which a piston 13 that can be acted upon by pressure medium from both sides and is connected to the gripper 10 via piston rods 13 slides. So that the rail grippers can also act as lifting devices, they are provided with pivotable holders 10 ″ that engage under the rail head. The aforementioned cylinder 11 has lines 14 ′ and 14 ″ for the purpose of supplying and removing pressure medium. Fig. 2 shows the operation of the machine by hand of the tension wire 8 clearly, with the other, z. B. stationary anchored end of the tension wire is visible. This end may, for example, be attached to a cart 12 which can be anchored to the rails 2 and which the tamping and straightening machine gradually approaches as the work progresses, with the wire 8 kept under constant tension providing the reference base for monitoring the required level . Patent claims: 1. Device for aligning a track side and height with a straightening device which grips the track by means of a motorized rail gripper and raises and moves it until the track has assumed the correct position in relation to a reference base that defines the target position, and which is located in the working direction in front of the tamping tools of a track tamping machine working together with it and traveling on the already aligned part of the track, characterized in that the straightening device is arranged in a part of the chassis frame of the track tamping machine that protrudes over the track area to be corrected on the front side of the front axle of the track tamping machine and the rail grippers (10) can be moved laterally and vertically by a motor. 2. Device according to claim 1, characterized in that the means carrying the rail grippers (10) are mounted laterally displaceably by motor in a motor-driven, height-adjustable guide (11).
