    13 cars. One of the undercarriage carts
    14, the machine is equipped with a drive 15. On the frame 2, a device 16 is also mounted for lifting and leveling the track, rearranged in a vertical plane by a hydraulic cylinder 17 and including support rollers 18 and lifting rollers 19, which capture the rail head from below and outside the track. In order to apply lateral toggling forces to the rail, the device 16 is moved across the path by hydraulic cylinders (not shown). The machine is equipped with a leveling system, consisting of the sight wire 20, connected to the indicator bodies 21 and 22. The indicator body 22 located near the unit 4 carries a measuring element 23 at the upper end, made in the form of a potentiometer, which allows determining the position deviation track height in relation to the sighting wire 20 and which controls the device 16, correcting the path in the profile.
    In the cab 11, a digital pointing device 24, a device 25 for controlling the position of the unit 4 in a vertical plane, and a unit 26 for controlling the speed of movement of the unit 4 are mounted. vertical plane. The device 25 is connected to the power unit 13 through the pressure pipe 27, and through the control pipes 28 and 29 to the cavities of the hydraulic cylinder 3. The device 25 includes a sensor 30 of the position of the unit 4 in the vertical plane, made in the form of a potentiometer. Sensor 30 is mounted on frame 2 near unit 4 and contains a vertical direction rod 31, slider 32 mounted on it, communicating with a lead 33 mounted on frame 9. Slider 32 is connected to the cable system 34, from which the upper unit rotates the potentiometer 35 / which through pipe 36 is connected to device 25
    Figure 2 shows the unit 4, and the dotted lines show three other positions in the vertical slope, which correspond to the position of the sensor 30, marked a, b, c. The position a corresponds to the upper position of the unit 4, 6 - its position at the head level rail, in - the position of the unit 4 at the time of its loading into the ballast, and g - the previously selected depth of the tools 7 into the ballast. Each of these positions corresponds to a certain output signal from the sensor 30, which is used to control the movement of the unit 4 in the vertical direction.
    The control unit 26 for controlling the speed of movement of the unit 4 for compacting the ballast under the sleepers in the vertical plane contains a differential amplifier 37, one input of which is connected through an amplifier 38 to the sensor 30. The amplifier 38 is connected to a zero setting link 39. The second input of the differential amplifier 37 is connected via a switch 40 and a time delay element 41 to the sensor 42 of a predetermined immersion depth of the instruments 7. Following the differential amplifier 37 in parallel circuit, the adjustable amplifier 43 intended for the lifting process is included, and for the lowering process, the amplifier 44 optionally, through switch 45, they are connected to the first input of the second differential amplifier 46. The second input of this differential amplifier 46 is loaded with the compare signal of the splitter 37. In the parallel circuit for both inputs of the second differential amplifier 46, a zero switch 48 is provided, which controls the relay 49 with a switching contact 51 via switch 49. Following the second differential amplifier 46, the power stage 52 is turned on, which through the switch 53 is optionally connected With one of the two outputs 54 and 55, respectively, of the regulating and control device 25. The device 25 also includes switching bodies for the independent implementation of working processes, for example, the process the carriage of the way and started compacting ballast. As a switching element, a Schmitt trigger 56 with an adjustable response level is provided for the process of raising the path. The trigger is loaded by the control signal of the sensor 30 guided through the amplifier 38. This Schmitt trigger 56 controls the relay 57 by means of a switching device 16 installed in the control current circuit contact 58. The following Schmitt trigger 59 is provided as a switching body to start the ballast compaction; one input of which is also loaded by a control signal directed through the amplifier 38 sensor 30, and the second input is directly connected to the sensor 42. Schmitt trigger 59 controls the relay 60 by means of a transverse supply of tools 7 of the switching contact 61 installed in the control current of the drive 6 of the switch. FIG. 3 designates all switches 40, 45, 49 and 53 in position for raising the unit 4. In order to bring these switches to the position for lowering the unit, a relay 62 is provided that is controlled through the foot pedal 63 by the operator of the machine, to which the switches 40, 45, 49 are movably connected and 53, as shown by the dotted lines . Through the 1switch 64, the pointing device 24 can either be loaded by the guiding signal of the sensor 30 through the amplifier 38, or directly connected to the sensor 42. The block 26 turns on the electromagnetic spool 65, which through the pressure pipe 66 is loaded by the hydraulic working fluid supplied by the pump 67 from reservoir 68. The working fluid drain pipe is marked 69. The outlets of the spool 65 are connected to “teres piping 28 and 29, respectively, with the rod and rod cavity of the hydraulic cylinder 3. systematic way supply of working fluid in the cavity gydrotsilindra 3 takes place through the outputs 54 or 55 unit 25. The machine operates as follows. In preparation for lowering, unit 4 is in position a (Fig. 2). The sensor 42 is adjusted to the desired immersion depth (position t, Fig. 2). The zero value indication is controlled by a link 39 at a predetermined level, for example, position 5. The positions lying higher in height are shown on the pointing device 24 as positive values, lower lying positions as negative values. The trigger level of both the Schmitt triggers 56 and 59 is adjusted to the specified values, i.e. to those positions in height at which the process of raising the track and the process of compaction of the ballast must begin. Next, using a voltage divider 47, a comparison signal is supplied to the second differential amplifier 46. This comparison signal is chosen so that the output signal of the second differential amplifier 46 amplified in power stage 52 covers the current requirement of the lowering control valve spool 65 for the minimum supply flow working fluid through the pipeline to the rodless cavity. hydraulic cylinders 3. Soft start from unit 4, from the upper end position. By operating the foot pedal 63 by the machine operator, all the switches 40, 45, 49 and 53 are brought to the Lower position. Simultaneously, comparisons of the value received from the sensor 30 with the given value of the sensor 42 are entered. The specified value is not supplied to the second input of the first differential amplifier 37 at once for its entire value, but
    gradually increasing due to the given element 41 of the time function. An increasing difference voltage in the first differential amplifier 37 arises between the actual and target values, which through the amplifier 44, the second differential amplifier 46, the power level 52, the output 54 and the pipeline 70 controls the regulating magnet to lower with increasing current. As a result, a gradually increasing quantity of working fluid is supplied to the rodless cavity of the hydraulic cylinder 3 through the pipe 28, so that the rod of the hydraulic cylinder 3 together with the frame 9 moves downwards with an increasing speed. As soon as the difference between the actual and a predetermined value reaches a maximum, the spool 65 is fully open and the cylinder rod 3, and accordingly, the unit 4 reaches the maximum lowering speed. Thus, the sensor 42 and the element 41 form a sensor controlling the speed of movement of the unit 4 in the vertical plane.
    The process of alignment; As soon as the difference between the actual and specified values exceeds the triggering level of the Schmitt trigger 56, the relay core 57 is retracted and closes the contact 58. Meanwhile, the device 16 is turned on and the path is straightened in the profile and plan directly by the unit 4 to seal the ballast under the sleepers. Unit 4, meanwhile, passes the zero position b and reaches the position in which the process of immersing the tools 7 in the ballast of the track begins.
    The process of immersion and deceleration (damping) of the process of lowering the unit 4. When a certain depth position is reached (for example, approximately 120 mm above the desired depth previously adjusted on sensor 42), the open position of the spool 65 is adjusted in the opposite direction from maximum to minimum value corresponding to voltage divider 47. Comparison signal. Fluid flow through spool 65 and pipeline. 28 to the rodless cavity of the hydraulic cylinder 3 is reduced to a minimum value. At the moment of exact coincidence of the actual value with a predetermined value (zero difference), the zero switch 48 operates and switches the control current for the spool 65 all the way to zero. The spool 65 stops the flow of the working fluid through the pipeline 28 to the rodless cavity of the hydraulic cylinder 3, and the unit 4 stops without strikes with an accuracy of one millimeter in the t position,
    those. at a predetermined immersion value.
    The start of the ballast compaction process. As soon as the difference between the specified and actual values exceeds the triggering level of the Schmitt trigger 59, the relay 60 is controlled and the process of ballast compaction starts by closing the switching contact 61. When using a Schmitt trigger 59 with an adjustable trigger level, the beginning of the ballast compaction process may, under certain conditions, be pre-biased so that the transverse feed actuators 6 of the instruments 7 are triggered several centimeters before reaching the predetermined immersion depth (position g, fig.2) for of the lowest position of the tools 7. In this way, with very hard blasts, the penetration of the tools 7 to a predetermined depth is facilitated so that no significant No time lost.
    Return unit 4 to the upper end position. By releasing the foot pedal 63 or the automatic command of the output of the unit 4, all switches 40, 45, 49 and 53 are reversed to the position shown in FIG. 3 for raising the unit 4. The predetermined value of the upper end position, gradually age, through the intended lifting process the element is fed to the second input of the first differential amplifier 37. Thus, also when lifting the unit, soft pulling away from the lower end position (position d) occurs. Before reaching the position of the upward movement of the unit 4 in the same manner, the lowering process is slowed down and, accordingly, is damped through the second differential amplifier 46 so that, when the upper end position is reached, the unit 4 is free from shock and the position of the unit 4 can be periodically controlled on the pointing device 24.
    The tamping machine allows it to accurately maintain the required depth of tamping tools in the ballast, even with different fractions of the blaster, while providing optimal control of the speed of movement of the tamping tools, which increases its efficiency.
