Definitions

  • the invention relates to a tamping unit for a track tamping machine with arranged on a in a Stopfaggregatrahmen height adjustable, arranged carrier, designed as rocker Stopftechnikmaschinefaren whose immersion in a ballast certain lower tufting ends with a vibratory drive in opposite directions drivable and hydraulically to each other bei constructive.
  • Tamping units penetrate with gravel tools the gravel of a track bed in the area between two sleepers (intermediate compartment), in the area of the support of the threshold in the ballast under the rail and compact the ballast by a dynamic vibration of the tamping between the opposable tamping pegs that can be provided. Tamping units can plug one, two or more sleepers in one work cycle ( DE 24 24 829 A ).
  • the movements of a tamping unit include the vertical immersion of the tamping pick in the ballast, the Beistellieri in which the tamping ends are closed to each other and the superimposed dynamic oscillation which causes the actual compaction of the ballast grains.
  • Other known solutions use linear excitation via hydraulic cylinders. Two hydraulic cylinders are mechanically coupled in series. The one hydraulic cylinder performs the Beistellieri, the other the vibratory movement.
  • the size of the resulting vibration is determined mechanically and by the hydraulic excitation.
  • the size of the amplitude can not be adjusted freely.
  • Optimal stop frequencies for compaction are known to be between 25-40 Hz, with penetration of the tamping pick in the ballast with higher frequencies is easier, since only a small immersion shock occurs and thus the stress on the bearings of the tamping unit can be reduced.
  • the tamping units in use today have a very high and costly maintenance. Typically, the units are at least partially overhauled and maintained every season. After 1-2 overhauls, the units must be replaced by new ones.
  • the amplitude decreases due to the elasticity of the hydraulic hoses and thus the compression effect decreases. From various studies it is known that falling Stopfamplituden affect the compression and also reduce the penetration into the ballast.
  • the invention is therefore the object of tamping units of the type described with simple means in such a way that the stability of the vibration drive is significantly increased.
  • the invention solves this problem in that each of the stuffing tools of a Stopfwerkmaschinefares a hydraulic cylinder and a displacement sensor for determining the hydraulic cylinder position are assigned, wherein the hydraulic cylinder form the Beistellantrieb and the vibration drive of the stuffing pick and the control of the hydraulic cylinder wegsensorsignalcommun.
  • a single common hydraulic cylinder is used for the Beistellterrorism and the vibratory movement of at least one stuffing pickle (possibly also of several synchronously driven stuffing pickles of several pairs of stuffing needles).
  • the hydraulic cylinder is a Assigned encoder, for example, always detects the exact exact position of the hydraulic piston. Since no rotating parts are provided in the power stage of the drive in contrast to the prior art, the stability of the vibration drive is considerably improved with the simplest construction.
  • Hydraulic cylinder control valves in particular servo or proportional valves, which are arranged directly on the hydraulic cylinder, are recommended for actuating the hydraulic cylinders.
  • the hydraulic lines should be as short as possible, so that the elasticity, the storage effect (damping) of the hydraulic hoses under the impact load, is kept low.
  • Typical requirements are amplitudes of 3-6 mm at the tamping ends at a maximum frequency of 50 Hz. Compression amplitudes close to the upper limit are better, for example, for loose gravel (after track cleaning and track renewal or new track construction).
  • the current hydraulic cylinder position is detected by the built-in hydraulic cylinder or externally mounted displacement sensor. Any suitable function sensor can be used.
  • the detected position is compared, for example, with a desired position and the respective Hydraulikzylinderan Kunststoffventil with the difference driven according to what a control or regulation is provided.
  • the hydraulic cylinder position can thus be predetermined or regulated by a control / regulation as a function of the displacement sensor signals, wherein in particular a linear Beistellterrorism the hydraulic cylinder, a vibration is superimposed.
  • the control / regulation gives the vibration, the vibration amplitude and the vibration frequency, depending on the height and the auxiliary position the tufting ends before.
  • the setpoint position is specified by an electrical signal course. For this purpose, for example, for a linear Beistellterrorism a linearly increasing voltage (ramp) is specified.
  • the opening width of the tamping unit corresponds to a certain predetermined voltage.
  • the oscillation in turn corresponds to an alternating voltage superimposed on the supply voltage.
  • the amplitude of the AC voltage then corresponds to the vibration amplitude and the frequency of the AC voltage of the stop frequency.
  • the main advantages of the invention are the simple construction, which does not require wear-prone rolling bearings, connecting rods and connecting rod bearings of the coupling of the auxiliary cylinder on the vibration wave and does not require a flywheel.
  • the Stoppffaggregatö Wennsweite ie the distance between the tufting ends, infinitely adjustable and is any free preselection of the stop frequency, for example, a dip of the pimples with 50 Hz for a low insertion shock and a compression at 35 Hz in working position the pimples to reduce wear and of noise, easily possible.
  • a continuous adjustment of the stuffing amplitude and its signal shape allows an optimal adaptation to the respective superstructure conditions. If a control loop is provided, an automatic readjustment of the plug movement takes place in the event of resistance changes by the control loop, thus ensuring that the desired plug amplitudes and frequencies are maintained.
  • the Beistellweg will be specified by the controller / regulation.
  • the control / regulation specifies the oscillation, the oscillation amplitude and the oscillation frequency as a function of the cylinder pressure measured, in particular with a pressure sensor. So can be deduced by a pressure measurement in the hydraulic cylinder on the compaction of the ballast bed.
  • a tamping unit 1 for a tamping machine comprises, inter alia, arranged on a support 2, designed as a swing lever Stopftechnikmaschinepare with Stopftechnikmaschineen 3, whose intended for immersion in a ballast 4 lower tufting ends 5 with a vibratory drive 6 in opposite directions drivable and hydraulically to each other, with a Beistellweg s, bei constitution are.
  • the carrier 2 is guided vertically adjustable in a Stopfaggregatrahmen 7 with guides 8 and displaced with a control cylinder 9 in the desired altitude.
  • the stuffing tools 3 are designed as two-armed levers which are pivotally mounted on the carrier 2. One arm of the respective stuffing tool 3 is formed by a tamping pick 10 and on the other arm engages a hydraulic cylinder 11, which in turn is mounted on the carrier 2 at the other end.
  • Each of the stuffing tools 3 of a pair of stuffing tools are a hydraulic cylinder 11 and a displacement sensor 12 for determining the hydraulic cylinder position assigned, wherein the hydraulic cylinder 11 form the Beistellantrieb as well as the vibration drive for the tamping pick 10 and the control of the hydraulic cylinder 11 takes wegsensorsignaljon.
  • the displacement sensor 12 can thus always be used to determine the exact stroke position of the hydraulic cylinder 11, that is to say the distance between its two articulation points, at one end on the stuffing tool 3 and on the other end on the carrier 2.
  • the displacement sensor 12 and the hydraulic cylinder 11 form a structural unit and the displacement sensor 12 is integrated into the hydraulic cylinder 11.
  • Hydraulikzylinderan horrinsky 13 in particular servo or proportional valves, are provided for actuating the hydraulic cylinder, which are arranged directly on the hydraulic cylinder 11.
  • the supply lines of the hydraulics, so the pump lines and the tank lines are not shown for clarity.
  • the supply of the tamping unit with hydraulic energy via a standard hydraulic unit.
  • the hydraulic cylinder position can be predetermined by a control / regulation 14 as a function of the displacement sensor signals.
  • the control / regulation 14 is connected via control lines 15 to the Hydraulikzylinderan Kunststoffventile 13 and via measuring lines 16 to the displacement sensors 12.
  • the control / regulation 14 can specify the oscillation, that is to say the oscillation amplitude and the oscillation frequency, as a function of the altitude h and the auxiliary position s of the tamping pick 10.
  • the provision s and the vibration excitation of the tamping pick 10 is thus carried out by a hydraulic cylinder, wherein a hydraulic cylinder 11 per tamping 10 is provided or else a hydraulic cylinder 11 may be provided for a plurality of synchronously to be moved tamping 10.
  • Fig. 2 It is shown that a linear Beistellterrorism the hydraulic cylinder 11, a vibration is superimposed.
