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 Stopfwerkmaschinefaren whose immersion in a ballast certain lower tufting ends with a vibration drive counter driven and hydraulically to each other beinellbar, each the tamping tools of a Stopftechnikmaschinepares is associated with a hydraulic cylinder, wherein the hydraulic cylinders form both the Beistellantrieb and the vibration drive of the tamping and Hydraulikzylinderan horrventile are provided for actuating the hydraulic cylinder, which are preferably arranged directly on the hydraulic cylinder.
  • an adjustable opening width cylinder or opening width distance sensor may be provided for continuous opening width adjustment.
  • 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 . EP 1 653 003 A2 ). According to the teaching of EP 1 653 003 A2 the effective as a linear drive Beistellantriebe are designed such that these not only a linear Beistellterrorism, but at the same time in one of the AT 339,358 , of the EP 0 331 956 or the US Pat. No.
  • 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 vibration 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 Beistell Gay, 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 stopping frequencies for compaction are known to be between 25-40 Hz, whereby penetration of the stuffing tamp is easier in normal gravel with higher frequencies, since only a lower immersion shock occurs and thus the stress of the bearings of the Tamping unit can be reduced. This is no longer the case for irregular heavily contaminated hard gravel beds.
  • frequency and amplitude advantageous.
  • 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 decreasing Stopfamplituden or a decreasing compression frequency 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 such that the stability of the vibration drive by the use of only one Hydraulikbeistellzylinders is significantly increased, but at the same time on the use of highly loaded displacement sensors in the cylinder and an indirect complicated control the disadvantages associated with it can be dispensed with.
  • the invention achieves the stated object in that at least one means for determining the oil flow, in particular an oil flow sensor, is provided in the hydraulic cylinder oil supply circuit and that the control of the hydraulic cylinder is dependent on the oil flow rate oil flow dependent such that a predetermined Beistellweg the stuffing tools is achieved.
  • Each of the stuffing tools of a Stopftechnikmaschinepares is associated with a hydraulic cylinder, wherein the hydraulic cylinder form the Beistellantrieb as well as the vibration drive of Stopfpickel and the control of the proportional or servo valve takes place directly via the electrical valve input. At this control input, the signals are now electrically specified so that the desired flow through the Beistellzylinder arise.
  • the means for determining the oil flow allow the controllability of the hydraulic cylinder (positions).
  • the flow in the Hydraulikzylinderan tenueran may be measured, for example by an evaluation of the measured position of the valve piston in the valve.
  • a stopper auxiliary cylinder which is hydraulically biased.
  • the two cylinder pressures are measured by means of pressure sensors.
  • the vibration is switched off and the hydraulic cylinders are opened.
  • the unit moves together until a mechanical stop on the auxiliary cylinder on the piston side strikes the stopper auxiliary cylinder previously set by the operator.
  • the pressure in the auxiliary cylinder increases at short notice. This increase in pressure is detected and evaluated by the controller and stopped the Beistellieri.
  • the opening width can be measured with, for example, a laser distance sensor or another distance sensor for the stop, and at the predetermined target width the auxiliary cylinder is stopped when moving together and held in this position.
  • a laser distance sensor or another distance sensor for the stop is another distance sensor for the stop.
  • shock valves which are pivoted in, for example, via compressed air cylinders as mechanical stops.
  • the hydraulic cylinder piston rod is then retracted until the mechanical stop is reached.
  • one has no continuously adjustable opening width but only two opening widths. This corresponds to the most commonly used tamping units today which still have shock valves. If distance sensors are used to control the opening width, then these can also be used to measure the auxiliary travel.
  • 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).
  • 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 control / regulation specifies the oscillation, the oscillation amplitude and the oscillation frequency, depending on the height and the supplementary position of the tufting ends.
  • the linear addition movement corresponds to a constant oil flow with pressure on the A side of the valve.
  • the nominal flow rate is predetermined by an electrical signal course. For this purpose, for the linear Beistellterrorism required as above corresponding to the Beistellieri superimposed on the sign changing vibration oil flow. The amplitude of the AC voltage for the oil flow then corresponds to the vibration amplitude and the frequency of the AC voltage of the stop frequency.
  • the main advantage of the invention is the simple construction.
  • the Stopfaggregatö Maschinensweite ie the distance between the tufting ends, infinitely adjustable and is any free preselection of the stop frequency, such as immersion of the pimples at 50 Hz for a low insertion shock and a compression at 35 Hz in working position to reduce wear and 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 circuit is provided, a Automatic readjustment of the stuffing movement with resistance changes by the control circuit, thus ensuring compliance with the desired stuffing amplitudes and frequencies.
  • the Beistell Gay is controlled and / or regulated by the controller / regulation.
  • the control / regulation it is advisable for the control / regulation to readjust the oscillation, the oscillation amplitude and the oscillation frequency accordingly, depending on the comparison of the desired flow to the actual flow, in particular with a flow meter, the oil flow , With the help of the pressure sensors, the achieved compacting force can be measured. If the maximum possible degree of compression is reached, the optimal time is to stop the plug. Otherwise, the compacted support will be reduced in area by drainage of compacted ballast.

  • a servo valve or a proportional valve 12 In the hydraulic cylinder oil supply circuit, there is an oil flow sensor 14. The pressure is generated via a hydraulic pump 15. The oil is sucked by the pump 15 from the hydraulic tank 16 via the oil flow sensor 14 to the control valve 12. Depending on the control of the valve 12, either the A connection or the B connection is supplied with pressure.
  • the auxiliary movement takes place when the A-side is pressurized, the opening movement when the B-side is pressurized.
  • the ballast 19 is compressed by the tamping 17 below the threshold 18.
  • the compacting movement 20 of the pickle 17 consists of a continuous closing movement 22 and a superimposed oscillatory movement 21.
  • a hydraulically preloaded position cylinder 8 with integrated displacement sensor 24 can be adjusted by the operator continuously to the desired opening width 25.
  • booting into working position now closes the side cylinder 5 until the mechanical stop 7 on the stop. 9 occurs.
  • the resistance generates a pressure peak in the auxiliary cylinder 5 which is measured via the pressure sensor 11.
  • the electronics 25 detects this pressure peak and automatically switches off the further movement of the auxiliary cylinder 5. With this device, any desired opening width 25 can be set by the operator.
