    body moving along the straightened path, and together with frame 4 moves along the path irrespective of frame 3,
    5 For each position of frame 4 with respect to frame 3 of the machine, the same distance ratios and measurement conditions for interacting with the base system 15 are provided.
    10 bodies registering the actual position of the track, as well as a constant ratio of error reduction, the possibility of longitudinal movement of the frame 4 relative to the frame 3 of the machine makes it possible to adjust the installation of the required magnitude of the elevation of the straightened path of a predetermined center distance between trolley 12 and the following trolley
    20 1 cars. For large rises, this distance, shown as a dotted line, must be kept as small as possible.
    to maintain as long as possible the longitudinal zone of the path between the front chassis trolley 2 and the higher-level working body 9, through which the path from its initial level rises to a predetermined level and, accordingly, is deformed in order to avoid excessive load and residual deformation. railings during lifting. When only a slight rise of the track is required, the center distance between the trolley 2 and the next trolley 1 following it is held correspondingly large.
    The longitudinal movement of the frame 4 in relation to the frame 3 of the machine makes possible the continuous non-stop movement of the machine or its frame 3 during the process of tamping the sleepers. At the same time, the frame 4 remains in place with double sleepers during the tamping of the sleepers by the tamping body 7, centered on both adjacent adjacent sleepers, while the frame 3 of the machine together with the supporting section formed by the rollers 6 is continuously moving forward in the direction of arrow A, On the same magnitude as the piston of the power cylinder
    .5, Upon reaching the desired degree of compaction of crushed stone ballast, the working body 7 is lifted under the two sleeper knocks, with the help of actuators 8 for moving in height, and
    ; Thereafter, the double acting drive cylinder 8 is loaded in the direction indicated by arrow B. Rama 4 is subjected at relatively high speed by an amount equal to approximately s, but three distances between the sleepers until the tamping device 7 will be in the centering position with respect to the subsequent pins to be driven, south facing ahead.
    In the second embodiment of the machine (Fig. 2), the frame 3 "consists of two 17 parts pivotally interconnected by a swivel support, under which a trolley 18 is installed. On the front part of the frame 3 there is a tamping 7 and a straightening 8 working members. In the second part of the frame 3, an additional frame 4 is installed, one end of which rests on the carriage 12, and the second, made in the form of a longitudinal beam 13, through the roller 19 rests on the rail
    ne
    20, made in the frame 3 of the machine. Frame 4 is mounted on the frame 4 and straightening 9 working members, frame 4 by the cylinder 5 is moved relative to frame 3. The machine is equipped with a control device, including measuring bodies 21, placed between the spindle and piercing and working tools, and the base the system in the form of a cable 22 connected to the sensors — 35 — the position of the track in the process of operating the machine, interacting with the track rails. Measuring organs 21 are rotating potentiometers connected to sensors 40, interacting with cables 22 and are designed to determine the difference between the desired and actual positions of the track and the size zones, working bodies 7 and 9. Recording workers The bodies 9 have their own measuring and measuring system consisting of a cable 24 passing mainly along the axis of the path, tensioned between the front 25 and the rear 50 measuring trolleys. The cart 25 moves along an un-straightened path, and the cart 26 is straightened. to the path, S. cable 24 interacts probes (not shown), installed on sensors 23 and intended to determine the differences between the given and actual arrows
    bending the path in the areas of placement of the working bodies 7 and 9. During the work of the machine, only working bodies 7 and 9 can be used, mounted on the front in the direction of movement of the machine of the frame 3 (along arrow A) during cyclical operation of the machine or working bodies mounted on the rear parts of the frame 3, with continuous movement of the machine. When all the working bodies of the machine are working, the front tamping tool body 7 is first centered relative to the pitch, and then the rear tamping body 7 is centered relative to the line to be slept. It is possible to simultaneously use the tamping workers 7 at different distances between the sleepers. When operating the machine, a large climb of the track is possible due to the successive lifting of the track by the cutting working members 9,
    Figs 3 and 4 show a preferred embodiment of the machine, according to which frame 4 is mounted on frame 3 in the same way as version H) t 1, whereby the roller guide consists of two pairs of rollers 6 placed one above the other and installed with the ability to interact respectively with the lower and upper surfaces of the beam 13, the distance between the rollers 6 in the longitudinal direction being longer than the movement of the frame 4 relative to the frame 3, the Machine has a drive 27 of the trolley 2, the direction of operation is indicated by arrow A. two cabins 28 and 29 for maintenance personnel and a power installation 30. The rectifying tool 9 is guided on its way by rollers 31 with a bridge and has lifting rollers 32 interacting with the lower part of the rail head at the location of the frame 4 consists of two longitudinal beams 33, the ends of the cables 22 of the control and measuring device of the machine are connected to the sensors 23 of the track position, one of which is placed on the non-corrected path, and the second on the straightened path. One sensor 23 is placed in the zone of the track alignment on each track rail, these sensors are connected with the measuring bodies 21, the machine is equipped with additional devices.
    which provide automatic control of machine working elements and contain a control unit 34, which is connected by wire 35 to power plant 30 and has a valve 36 through which the power cylinder 5 moves the frame 4 through a pipeline .37 The machine has a sensor integrated with sensor 23 38 of the distance traveled, which, through each centimeter of the distance traveled by the machine, supplies the control valve 36 with a control signal regulating the supply of working fluid to the right cavity of cylinder 5 so that frame 4 is Until the end of the process of tamping the sleepers, the barrel 7 remains stationary relative to the sleepers being pushed,
    At the time of launching the tappet workgroups 7, the distributor 36 is reversed, using limit switches, the left cavity of the cylinder 5 is loaded by compression and the frame
    4 moves forward at high speed, 25 with sensor 23; measuring element 21
    until the tamping arms 7 are in the centering position relative to the next tie to be laid. Simultaneously with lowering the tamping devices 7, the path sensor 38 is set to zero, after which a new operating cycle begins. The same movement is obtained using the relative movement between frame 4 and frame 3 of the measuring unit machine, which in the case of the example of implementation is designed as potentiometer sensor 39 of rope cable (rope tension); In this case, the piston movement of the cylinder 5 is proportional to the movement of the movement or having achestve signal output voltage potentiometric sensor 39,
    A third possibility of controlling the distributor 36 is to install an inductive sensor 50 40 cooperating with rail fasteners on frame 4 approximately along the axis of symmetry of the tamping tool body 7. This sensor 40 behaves neutral as long as it is in the centering position with respect to to the corresponding rail fastening or to the sleeper to be assembled. When deviating from its centering, 1 inductive sensor 40 transmits to the distributor 36 a control signal that increases or decreases depending on the deviation of the supply of working fluid to the power cylinder 5. Thus, the tamping tool 7 remains until the end of the work of tamping the cross tie in the centering position
    towards her.
    In this case, it is possible to install the frame 4 on the way by braking the carriage 12 and simultaneously adjusting without movement of the cylinder 5 the movement of the frame 4 during the tamping of the sleepers.
    During the slewing procedure and the continuous advancement of the machine {{}} sp. 3), the remote ratios change and the ratio of the errors in the control and measuring device is reduced. In the front end position of the frame 4, indicated by a thick line, connected

    is relatively large distance a from the rear base end point 41 of the tension cable 22; Based on the total length f of the tension cable 22, the error reduction ratio is u (f, in the rear end position of the frame 4 shown by the dashed line The base end point 41 is reduced by an amount {so that an error reduction ratio equal to is obtained. This means that the error reduction ratio takes on an optimum value by the end of the tie-up process, i.e., by the final Track guidance, Control unit 34 is provided with a correction or computational authority 42, which is connected by wire 43 to a measuring body 21, with a distance sensor 38 or a potentiometric sensor 39, which compensates for the effect of varying distances from Q to B to Hb1 alignment.
    The combined base system (FIG. 5) is suitable, for example, for installation in a straightening-tamping machine, the structure of which is shown in FIGS. 3 and 4. The peculiarity of this basic system is that it is independent of the frame 3 of the machine together with the supporting bodies. 7 and 9, frame A gradually moves in the longitudinal direction of the path from one place of the tie of the sleepers to another in the direction of arrow A. For this purpose, a mechanism 44, which is installed mainly along the axis of the track, is provided as an initial straight line, which extends from the front measuring trolley 45, which runs along the straightened path, to the rear measuring trolley 46, which moves along the vertical traverse, and which is coupled by a drive 8, is tamped to the frame 4 by the connecting node 47. The latter, acting, for example, on the carriage 12 of the frame 4, is designed so that it ensures that the mechanism 44 is gripped in the longitudinal direction of the path and does not interfere oh mobility mechanism 44 across the path. As a leveling base system, a tension cable 48 is placed over each rail of the track, stretched between the measuring trolleys 45 and 46. The frame 4 / gauge 21, which cooperates with the working unit 7, is related to the frame 4 / gauge 21. 4 relative to the frame 3. The rod 54 of this hydraulic cylinder is connected to the coupling 53. The outgoing working body 9 is mounted on the frame 4 by means of the rod 55 and hydraulic cylinders 10. The working body 9
    20 is equipped with guide rollers 31 with a flange and lifting rollers 32. The machine is equipped with an optical base system located above each rail of the track and consisting of
    vuv with basic system for register-25 sensor 56, for example infrared
    of the difference between the real and the given set of repair path in plan and profile. For this, it has on each rail of a track made as
    35
    40

Another probe 50, installed on the measuring body 21, interacts along the path axis with the mechanism for registering the differences between the actual and the path specified by the arrows. . This basic system has a constant error rate of C / B errors, so that the installation of a correction or computing authority 42 is redundant.
