The purpose of the invention increase the efficiency of the machine by providing an automatic continuous monitoring of bearing path.

To achieve this goal continuously moving machine for controlled alignment the containing supported on the undercarriage with drive frame, at least one stabilizing unit mounted on the frame with the possibility of replacing the height and vertical loading actuator and includes a vibrator directed transversely of the machine horizontal oscillation, and a frame mounted on the power drive control and measurement system is mounted on the frame sensor of the distance and the two level sensors, one of which is mounted on the frame in front in the direction of operation of the machine part, and the second in the area of the stabilizing unit. The control unit drives made with the comparison element and a memory element connected to the specified one level sensor and the sensor distance traveled for the issuance of a delay signal of the specified one of the level sensor. The output of the memory element and the second level sensor is connected to the element of comparison, the output of which is connected with the actuator vertical loading stabilizing unit. One level sensor is mounted to the first direction of operation of the machine measuring trolley system position measurement path. The machine is equipped with a third level sensor, soedinenii with the control unit and mounted on the latter in the direction of operation of the machine measuring trolley system position measurement path. Drives vertical loading stabilizing unit, located on different sides of the longitudinal plane of symmetry of the machine, connected to the control unit with the possibility of independent from each other enable.

In Fig. 1 shows a continuously moving machine for controlled alignment the General view of Fig. 2 is a top view of Fig. 3 colorwave alignment path has an elongated machine frame 4, based on the one hand through the undercarriage 2, path 3, which by means of drive 5 trucks 2 and the Central power unit 6 is moved in the direction indicated by the arrow 7. In one of the two cabins 8 driver is the Central unit 9 of the control performed by the memory element. In the middle between the two driving trucks 2 are two stabilizing unit 10 arranged one behind the other in the longitudinal direction of the machine and pivotally connected to traction frame 4. To provide additional vertical load between the roll assemblies 10 and the frame 4 is provided by hydraulic actuators 11, loaded with the help of the control unit 9. Stabilizing the aggregates contain 10 rail grips with four rollers 12 with crests and two roller plates 13, pressed against the outer side of the rails.

Two synchronized vibrator 14, having a centrifugal force equal to 320 kN, lead the way 3 in the horizontal vibrations directed transversely to the longitudinal direction of the machine. The frequency is set in the range of 0 to 45 kHz. The load acting on the path 3 with a total of four actuators 11, respectively, approximately 100 kN. Proportion is the first direct reference chord, stretched over each rail thread and spaced along the measuring machine trolley 17 rolling path 3. Using another measuring truck 18 having a height sensor in contact with the chords 16, manage and control the lowering path 3 by corresponding regulation of the additional load.

In the front in the direction of the work machine 1 parts installed sensor 19 located at some distance from the stabilizing unit 10 in the longitudinal direction of the machine and attached to the front of the measuring trolley 17 reference system 15. The sensor 19 is designed as an electronic precision pendulum. With the front-running truck 2 soedin sensor 20 of the traversed path, rolling along the rail 3. Between the two roll assemblies 10 mounted the second sensor level 21, which is fixed on the floating height of the measuring trolley 22 rolling path 3. Also back in the working direction of the machine measuring trolley 17 is equipped with a third sensor 23 level. The sensors 19, 21, 23 level as the sensor 20 of the traversed path, the actuator 11 and the vibrators 14, connected to the control unit 9, which is designed for the intermediate storage of the measured value is ICI 2 on each longitudinal side of the machine is moved in the transverse and vertical directions of the side plow 24, with which of necessity gravel is transferred from the side zone rails of a track. Directly behind him and crushed stone plow 25 for processing the Central zone of the path connected to the frame 4 with the possibility of vertical movement. Rear in the direction of the end of the machine 1 is connected via a hinge with an auxiliary frame 26, the rear end of which rests through a running cart 27 on the path 3. To control the lowering of the way done with the help of stabilizing units 10, is provided for controlling and measuring system 28. Sweeping brush 29, revolving around a transverse axis with the cross-belt conveyor 30 is fixed on the additional frame 26 with the possibility of vertical movement and is used to remove rubble lying on the sleepers.

As soon as the machine 1 enters into the zone with a constantly changing cross slope (elevation of one rail above the other) it is defined in the front area of the measuring trolley 17 using fixed thereto sensor 19 level and is stored in block 9 as long as the sensor 20 of the traversed path will not give the number of pulses corresponding to the distance between him and the second sensor 21 level. This means that the stored measured value p of the track section, in which the measured value was measured using the front sensor 19 (see Fig. 3).

In the field of stabilizing units 10 is known in cooperation with the reference system 15 is controlled by the lower path, and by a corresponding change in the speed of promotion and/or frequency of vibration and/or additional vertical, respectively, the main load P varies the height of the lower path. In case the cross track gradient, measured by the front sensor 19, for example in the area And the paths (Fig. 2), is registered corresponding to the measured slope value and saved in the memory element unit 9 as a set of values for the subsequent lowering of the way up until the sensor 20 of the traversed path will not be registered with the advancement of the machine, corresponding to the distance between the front sensor 19 and the second sensor 21. Reference system 15 for registration longitudinal profile path is enabled only on the base side of the path, i.e., newssystem rail road.

Using a second sensor 21 level, which is now due to continuous working promoting machine in the area And the path is the current measurement poperechnogo value is compared with the memorized value of the specified value. If the actual value is greater than specified, then additional vertical load P at stabilizing units 10 is increased by a stronger loading of the actuator 11 in the zone of elevated rail 31 in accordance with the value of the difference between x so that the transverse slope before working machine 1 is identical to the lateral slope after the controlled lowering of the way through the stabilizing units 10. By continuously comparing the transverse slope of the path in the working area of the transverse slope defined by the first sensor 19, almost copied for controlled lowering of the way, so after applying dynamic stabilizing units 10, the geometry of the path will remain unchanged. Dashed line 32 (Fig. 3) indicates that the value x of the difference is transmitted to the actuators 11 of the left hand side of the machine, if the rail 33 exalted to the right curvature of the path.

Through a subsequent third sensor 21 level it is possible to measure the cross slope of the road after applying units 10, for example, for the Protocol. For the case when the machine 1 has no additional frame 26, it would be possible reversal in its working direction. The third sensor 23 level is here to automatically compensate for various sizes downward path, emerging along the beams by respective different drive control 11, located opposite each other transversely of the machine.
