    Summary

    The invention relates to a tamping machine for compacting the ballast bedding of a track, with tamping units for tamping the track, with a main lifting device for leveling and leveling the track, which is arranged between drives, preferably in front of the tamping units in the working direction, with an additional lifting device for leveling and leveling one Track branching off the track in the area of a switch with a lifting roller that can be displaced with an actuator between a release position and a clamping position for gripping the branching track.
    Such tamping machines are known for example from EP 1 143 069 A. These are not only suitable for tamping lines but also for working in switches. The branching branch is lifted parallel to the main lifting device with the help of an additional lifting device. It is common with this additional lifting device to have double track roller wheels that roll on the rail and a lifting device that can be adjusted vertically by means of actuators and a lifting roller that grips the rail head. The device remains engaged while the tamping machine is continuously advancing in the working direction. EP 2 542 719 B1 describes an additional lifting device which, in addition to a flange roller, has two thrust rollers. When using double track roller wheels, there is no optimal form fit when closing the lifting roller of the additional lifting device, which is why the pliers tend to tear out. The single rail is difficult, because when lowering the additional lifting device, the double track roller must be lowered exactly over the rail. To ensure that the double track roller has a small run-up angle and that it does not climb and derail when driving forward, the operator must set the roller tangentially using the horizontal swivel drive of the additional lifting / 16 head. This is difficult because the operator in the cabin has difficulty viewing the point of application of the additional lift. In the version with two thrust rollers, the single iron is made easier, but it is a complex technical solution. When moving forward, the swivel control must be switched to float so that the thrust rollers can move the lifting head tangentially. For rail heads of different widths, the distance between the thrust rollers must be set manually. Since the branching branch of a switch, depending on the working direction, moves away or approaches the continuous main branch, the extension device and the swiveling device of the additional lifting device must be switched to float during the continuous approach. The telescopic arm is then extended or retracted via the Doppler flange roller or the flange roller with the two thrust rollers. A lateral force is exerted on the thrust rollers or the flanged roller. This is associated with the risk of the auxiliary lifting device climbing and derailing.
    DE 43 07 862 A1 shows a conventional design of an additional lifting device with a support arm, roller tongs and guide roller which is arranged at a certain distance from the main lifting device in the longitudinal direction of the track (typically 1.5-2 m). EP 3 303 703 discloses the integration of an additional lifting device into a main lifting device. Lifting and shifting drives are often implemented in hydraulic tamping machines using hydraulic cylinders.
    The invention is therefore based on the object of specifying a tamping machine of the type mentioned at the outset, in which the additional lifting device can be guided safely and easily during the right of way and which holds the branching rail securely when the lifting force acts.
    The invention achieves the stated object in that the additional lifting device has, in addition to the transverse and lifting forces on the lifting roller that transfers the rail head, a transverse forces on a rail head profile roller that transmits a rail head and a guide device that transmits normal forces to the rail head, 3/16, the branching track between the lifting roller having Rail head profile roller and possibly the guide device is within reach.
    With the rail head profile roller, transverse forces are to be transferred to a rail head. The guide device transmits normal forces to the rail head, forces which are introduced in the direction of a vertical axis of the rail profile, as essentially contact forces or forces for pressing the track into a track bed. The lifting roller can be used to transmit transverse and lifting forces to the rail head, the transverse forces transmitted from the lifting roller to the rail head being counter to the transverse forces transmitted from the rail head profile roller to the rail head. The rail head profile roller has a negative profile of a section of the rail head and rolls on the rail head during operation. This means a considerably larger contact area and thus better guidance of the rail head profile roller along a rail.
    An additional lifting device of a tamping machine designed in this way is characterized by a good positive fit and thus a very good grip. The design as a rail head profile roller ensures that even with an angular misalignment between the lifting head and a rail branching off the main track, there is no contact angle on the roller, which simplifies a single rail and is advantageous for gripping safety.
    If the lifting roller has to be opened during the drive due to obstacles in the track, then the derailment-safe, lateral guidance of the additional lifting device can be ensured by a vertically arranged guide roller, which is adjacent to the lifting roller in the longitudinal direction of the track, i.e. in the direction of the track in front of or behind the lifting roller, but with a safety distance to it Rail is arranged so as not to hinder a single iron of the additional lifting device. If the vertical guide roller has a certain horizontal distance, typically 3 -5 cm, the additional lifting device can be easily inserted.
    When the lifting roller is open, the additional lifting head slides over the guide device, which in particular has sliding plates and / or sliding rollers, on the rail. If you use these slide plates and / or slide rollers made of plastic or a similarly soft material, then a rail-friendly rerailing of the additional lifting head on the rails is ensured, without striking steel against steel.
    An angular misalignment between the lifting head and a rail branching off the main track can advantageously be compensated for if the additional lifting device has at the end an additional lifting head which can be pivoted about a vertical axis and to which return springs which return the additional lifting head to a neutral position are assigned.
    To ensure that the telescopic arm is not pulled out or retracted over the rollers when the machine is continuously moving forward in the working direction, the extension is measured with the help of the displacement sensor integrated in the extension hydraulic cylinder. After a few blocked thresholds, a mathematical compensation function (e.g. quadratic polynomial regression) can be calculated from the measured paths and extension positions of the telescope, which allows the extension or retraction to be calculated in advance depending on the working direction. With each further measurement, the pre-calculation becomes more precise. According to the invention, the tangential adjustment of the additional lifting head is unnecessary. Therefore, the drive for pivoting the additional lifting head can be dispensed with. To ensure a certain degree of flexibility and mobility, return springs can be used e.g. made of rubber for the swivel joint.

    A tamping machine 2 (FIG. 1) has bogies 12 which can be moved on rails 13. The operator can operate the tamping units 11, the additional lifting device 3 and the main lifting device 4 from the work cabin 15. The main lifting device can be moved in the longitudinal direction 8 of the track. The schematic drawing shows an additional lifting unit 3 integrated in the main lifting device 4. Another usual position of the additional lifting device 9 is shown in broken lines. The distance of this additional lifting device 9 from the main lifting device is 7. The longitudinal displacement drive for the lifting unit is 14. The machine works in the working direction 6. The Additional lifting device 3 has a lifting cylinder 16 for each side. 5 is a longitudinal adjustment of the lifting cylinders 16, 17 that is synchronized with the longitudinal displacement of the main lifting unit 8. A computer 34 is set up in the working cabin 15, which outputs control signals for the actuators and reads values from sensors.
    2 schematically shows an additional lifting device 3 according to the prior art, which is integrated in a main lifting unit 4, which comprises a lifting roller 24, an alternative lifting hook 25 and a straightening roller 26. The extension telescope 10, 20 of the additional lifting device 3 carries at the front end the additional lifting head consisting of a pivoting cylinder 29 of the lifting head, a locking cylinder 30 for the lifting roller 22 and a double track roller 21. The telescope is extended or retracted via an extension cylinder 33. A displacement sensor 35 is integrated in the extension cylinder 33. A lifting force is applied to the branching branch of the switch via the lifting cylinder 16 articulated on the machine frame. The additional lifting device can be pivoted about the joint 28 relative to the main lifting device. The position of the telescopic arm 10 relative to the main lifting device 4 can be measured via a displacement sensor 34.

    3 shows a diagram of the additional lifting device 3 according to the invention. The telescopic arm 20 can be extended or retracted via the articulated extension cylinder 33. If the additional lifting head 3 is pivoted horizontally about the axis of rotation A, then resetting forces occur by compressing springs 34 (e.g. made of rubber). The lifting roller 22 (drawn in broken lines in the open position) is opened or closed via the drive 30. A vertical guide roller 18 is constructed so that the additional lifting device 3 remains laterally guided when the roller tongs 22 are open. This is at a certain distance from the rail 31, so that the additional lifting device 3 (when the roller tongs 22 are open) can be inserted more easily. The rail profile roller 19 is adapted from the profile to the rail profile. This means that even if the track 31 is not tangent to the branching track, there is no run-on angle (such as, for example, with a flanged roller or double-flanged roller) that can lead to climbing. Derailment during the continuous right of way 6 of the machine 2 can therefore not occur. At right-of-way 6 with opened roller tongs 22, the additional lifting head 3 slides on devices 32 designed as sliding plates or sliding rollers. If these sliding plates or sliding rollers 32 are made of plastic or a similar material, the additional lifting head 3 is also placed on the rail in a way that is gentle on the rails. When the lifting roller 22 is closed, because of the perfect adaptation of the rail profile roller 19 to the rail profile and the lifting roller 22 to the underside of the rail head 22, there is a positive connection which reliably and safely prevents the additional lifting device 3 from being torn out during lifting.
    Fig. 4 shows the additional lifting head 3 according to the invention in the front view. According to the invention, the position of the vertical guide roller 18, the lifting roller 22 and the sliding plates or sliding rollers 32 can be seen in the drawing.
    Fig. 5 shows schematically the continuous main line and the branching line of a switch. The machine 2 moves in the working direction 6 in the longitudinal direction x. The deflection values yi of the telescopic arm 20 of the additional lifting device 3 and the forward positions Xi are measured via the displacement sensor 35 integrated in the deflection cylinder 33 and stored in the evaluation computer 34. Depending on / 16 depending on the right of way position, there are pairs of values Xi, yi. After storing a sufficient number of value pairs Xi, yi (typically 3), a mathematical approximation function is calculated. This can e.g. a polynomial quadratic regression (using the least squares method of deviation).
    This function would then look like this:
    y = f (x) = ax 2 + bx + c
    The coefficients a, b and c are then calculated on the condition that the following applies to the function:
    k k
    V (a, b, c) = ^ (yi - Ί) 2 = i = 1 i = 1 2 - a · x2
    -b-Xi
    c) 2
    The partial derivation and equation of the equation sides results in a linear system of equations in the three variables a, b and c, the solution of which provides the function f (x) we are looking for. While continuing to work with machine 2, function f (x) is recalculated after each newly stored pair of values Xi, yi. With the help of the function f (x) calculated in this way, the extension of the telescope f (x) can be calculated depending on the approach path x and controlled by the computing unit 34. The advantage is that the rail profile roller 19, the lifting roller 22 or the vertical guide roller 18 are guided without forces and therefore no horizontal forces occur and therefore derailment is impossible.
