Definitions

  • the invention relates to a machine according to the preamble of patent claim 1.
  • Such machines are known (DE-OS 1 534 072, AT-PS 359 112) and are used, after track laying, track renewal, track correction and bed cleaning work, in particular after track tamping work, to the ballast ballast with even filling of the sleeper compartments distribute and level and profile the bedding shoulders. If such machines are used with ballast plows behind track tamping machines, then they must in particular be able to fill up the depressions created when the sleepers are stuffed on both sides of the sleepers with ballast, which for this purpose moves from the side as far as the railroad plows and upwards It must be ensured that it arrives at these points and fills the holes that have generally arisen there. With the brush rotating around a horizontal transverse axis, the ballast lying on the sleepers is then removed and distributed between the rails, the superfluous ballast is thrown to the side over the rails.
  • ballast plow machine does not follow the track tamping machine evenly, but rather is used at longer intervals in such a way that it is tracked at a correspondingly high working speed whenever the track tamping machine has worked a longer section.
  • the invention has for its object to improve a ballast plow machine in such a way that a lateral upward movement of the ballast to fill the upper areas of the ballast shoulders and especially the ballast bed areas between ballast shoulder and rail, in particular the depressions created during tamping work, even at very slow working speeds can be achieved as they correspond to the average working speeds of a tamping machine.
  • a correspondingly controlled drive device which reciprocates a longitudinally displaceably mounted device on the chassis of a track tamping machine in such a way that it advances at an approximately uniform speed with respect to the track when the machine is gradually advanced is known for a ballast compactor.
  • the ballast plows and the brushes are therefore mounted on a frame which is mounted on guide rails so as to be longitudinally displaceable relative to the machine frame and can be moved back and forth by a drive device known per se such that when the machine is coupled an intermittently advancing track tamping machine moves this frame relative to the track at an at least approximately uniform speed which corresponds to the average working speed of the track tamping machine.
  • the ballast plow machine does not require any operating personnel.
  • Such a jointly advancing machine association comprising a track tamping machine and a ballast plow machine according to the invention therefore permits particularly economical and time-saving track processing.
  • the suspension of the individual plow plates is set up in such a way that they hit when they hit to give in individually to an obstacle against the action of a spring, preferably foldable backwards.
  • a further expedient embodiment consists in that at the outer end of at least one of the lateral ballast plows a ballast milling machine is installed which can be rotated about an axis which is at least approximately vertical in its working position, which, together with the ballast plow, is adjustable between a lower working position and a raised rest position and which can preferably be driven in one or the other sense of rotation.
  • a ballast milling machine is installed which can be rotated about an axis which is at least approximately vertical in its working position, which, together with the ballast plow, is adjustable between a lower working position and a raised rest position and which can preferably be driven in one or the other sense of rotation.
  • ballast milling machine also allows the ballast lying on this footpath to either be thrown in front of the plow slabs and thus used to fill up the upper ballast bed area or, if the ballast milling machine is reversed, to be flung to the side if ballast is available in abundance is.
  • the machine advanced in the direction of arrow F in the working direction has a frame 1 with undercarriages 2 which roll on the rails 3.
  • Guide rails 4 are provided on the frame 1 in the longitudinal direction of the frame, on which a frame 5 with rollers 6 is mounted so as to be longitudinally displaceable.
  • the guide rails 4 are formed by horizontal, U-shaped hollow profiles of the side parts of the frame 1, which prevent the frame 5 from being lifted or tilted.
  • the frame 5 has a stable support 7 located below the frame 1, on the two sides of which a lateral ballast plow 8 or 8 'is installed and on which, in addition, two axially adjacent rotating brushes 10 and 10' with axes 11 and 11 oriented transversely to the longitudinal direction of the track 11 '( Figure 2) are attached.
  • These brushes 10 and 10 ' which can be driven by hydraulic motors 9 and 9' mounted on their axes, are each located at the end of a lever 12 (FIG. 1) which is articulated on a lower projection 13 of the frame 5.
  • a cylinder-piston system 14 acts on this lever 12, the other end of which is articulated to an upper frame projection 15 and which allows the brushes 10 and 10 'to be adjusted from their lowered working position shown in the figures into a raised rest position.
  • ballast plows 8 and 8 ' are constructed identically.
  • the ballast plow 8 'lying on the right in the direction of arrow F and its parts have those with one Dashed reference numbers of the left ballast plow 8 and are therefore not mentioned every time in the following description.
  • Each ballast plow has a supporting part 16 with a plurality of plow plates 17 which are articulated to it and which lie side by side in a common plane and are pivotably suspended about an axis 18 oriented parallel to their lower working edge. Parallel to this axis 18, an eccentric shaft 19 is also rotatably mounted in the supporting part 16 and has the axis of rotation 20 (FIG. 4).
  • This eccentric shaft 19 is coupled to all plow plates 17 by two articulated eccentric levers 21 and a transmission rod 23 (FIGS. 4 and 5) articulated to them at 22 such that the plow plates 17 oscillate in the direction of the double arrow when the eccentric shaft 19 rotates (FIG. 4 ) can be driven about their pivot axis 18.
  • a hydraulic motor 25 located on the inner end thereof serves to rotate the eccentric shaft.
  • each of the plow plates 17 can individually give way when hitting an obstacle.
  • each plow plate 17 can be folded back against the action of springs 24 when it encounters an obstacle which does not give way.
  • the springs 24 designed as helical springs surround the axis 18 on both sides of the point of application of the transmission rod 23, on which the plow plates 17 with bearing sleeves 17a are rotatably seated.
  • One end of the springs 24 is supported against stops integrally formed on the bearing sleeves 17a or the plow plates 17, while the other spring ends, which face one another, rest against stops 23a, which are formed on the transmission rod 23.
  • the plow plates 17 can also be mounted in such a way that they give way individually against the action of a spring when hitting an obstacle.
  • the entire drive mechanism for the plow plates 17 is covered by an upper sheet metal housing 26.
  • ballast milling machine 30 or 30' mounted on the respective supporting part 16 (FIGS. 1 to 3), which either in one or about a vertical axis 31 or 31 'in the working position other sense of rotation can be driven by a hydraulic motor 32 or 32 'located directly on this axis.
  • Each ballast plow 8 or 8 ' can be adjusted relative to the frame 5 or the frame 1 of the machine about a horizontal axis 27 or 27' (FIG. 2) oriented essentially in the machine longitudinal direction and from its obliquely downward working position, which is shown in Figures 1 to 3 for the ballast plow 8, are pivoted into a raised rest position, which Figures 1 to 3 show for the other ballast plow 8 'and in which this ballast plow is oriented practically vertically upwards, so that it is at a crossing of the machine lies within the clearance profile 49 indicated by dashed lines in FIG.
  • the ballast plow 8 or 8 ' there is an essentially horizontal cylinder-piston system 29 or 29' (FIG.
  • each ballast plow 8 or 8 ' can be adjusted in its orientation relative to the longitudinal direction of the track, that is to say with regard to the angle which the ballast plow or its supporting part forms with the rail 3.
  • the position of the axis 33 for the ballast plow 8 is indicated in FIG. 3, which can be adjusted in the sense of the double arrow 35 by means of a cylinder-piston system 34 which acts on the carrier 7 on the one hand and on the ballast plow 8 on the other hand.
  • a frame 38 is also installed on the frame 1, in which the cab for driving or feeding the hydraulic motors 9, 9 ', 25, 25' and 32, 32 'mentioned and for adjusting the cylinder-piston systems 14, 29 mentioned , 29 'and 34, as well as the power supply and drive units serving for the cylinder-piston system 40, which will be explained later, ie essentially a hydraulic pump in the example under consideration, and the necessary control devices are accommodated.
  • the relevant pressure medium lines are not shown in the figures.
  • the machine is also equipped with a water tank 39, from which the ballast bed can be sprayed with water to prevent excessive dust formation.
  • the machine according to the invention is preferably intended to be coupled to a track tamping machine 50 which operates in intermittent, step-by-step operation and is indicated in FIG. So that during the work, despite the jerky advance, the ballast plows 8,8 'and the brushes 10,10' on the To move frame 1 of the machine at least approximately at a uniform speed corresponding to the average working speed of the track tamping machine, a special, known drive device 40 (FIGS. 1 and 3) is provided in the form of a hydraulic cylinder-piston system, which relative to frame 5 to frame 1 of the machine back and forth in the desired rhythm. One end of the drive device 40 is connected to an attachment 41 attached to the frame 1, while its other end is connected to an attachment 42 attached to the frame 5.
  • a special, known drive device 40 (FIGS. 1 and 3) is provided in the form of a hydraulic cylinder-piston system, which relative to frame 5 to frame 1 of the machine back and forth in the desired rhythm.
  • One end of the drive device 40 is connected
  • This drive device 40 is controlled in a known manner as a function of the intermittent feed movement of the track tamping machine 50 to produce an alternating movement of the frame 5 relative to the frame 1 in such a way that the frame 5 with the plows and the brushes relative to the track 3 is at least approximately uniform at a speed is moved, which corresponds to the average working speed of the track tamping machine 50.
  • the brush 10a indicated by dash-dotted lines in FIG. 1 illustrates a position of the frame 5 which is shifted forward.
  • the operation of the machine is illustrated in Figure 2.
  • the ballast plow 8 is pivoted sideways into an inclined position corresponding to the inclination of the bedding shoulder 43 to be profiled, in which it also assumes the obliquely forward-pointing orientation shown in FIG.
  • most of the ballast gripped by the plow plates 17 is shaken upwards along these plow plates 17 due to the dynamic effect which is generated by the oscillating drive of the plow plates 17 and thus reaches the bedding and into the bed in the direction of arrow 45 indentations created by stuffing the sleepers 44 on the outside of the relevant rail 3.
  • the frequency of the oscillating drive of the plow plates 17 and 17 ' can be adjusted by changing the speed of the motor driving the eccentric shaft 19 or, if necessary, by changing the reduction depending on the working conditions and the condition of the ballast and for example between 300 and 1000 vibrations per minute vary.
  • the vibration amplitude of the plow plates 17 or 17 'or their maximum deflection angle can be a few centimeters, preferably for example 5 centimeters, and can also be adjustable if necessary.
  • the driven ballast milling machine 30 cleans the path 47 running along the track at the foot of the bedding shoulder 43, on which the inspector walks along for the purpose of visual track inspection. If the ballast milling machine 30 is driven in the direction of the arrow 36 according to FIG. 3, the ballast milling machine 30 caught by the ballast milling machine 30 comes in front of the plow plates 17 and is therefore moved upwards; on the other hand, if the ballast milling machine 30 rotates in the other direction, the excess ballast is flung to the side.
  • ballast baffles 37 and 37 ' (FIG. 3) which are inclined upwards and outwards are fastened to the frame 5 in the region of the brushes 10, 10'.
  • the other ballast plow 8 ' is folded up into its rest position.
  • this horizontal ballast bed section 46 is used simultaneously, this horizontal ballast bed section 46 to level, for which this ballast plow 8 'is brought into a horizontal position. If the bedding shoulder to be profiled were located on the other side of the track in the illustration according to FIG.
  • ballast plow 8 ' would of course take over this profiling, while the ballast plow 8 either folded up into its rest position or was set horizontally for leveling the horizontal ballast bed section becomes. If both bed shoulders are to be profiled on a single-track line, this can of course be done simultaneously with the machine according to the invention by the two appropriately oriented ballast plows 8 and 8 '.
  • the invention is not restricted to the exemplary embodiment described, but rather permits numerous variants.
  • hydraulic drives pneumatic or electric drives can also be provided.
  • the drive motors can also be accommodated in the cabin 38 and the parts to be actuated or driven can be connected to these motors by means of appropriate gears or motion transmitters.
  • the number of plow plates 17 or 17 'per ballast plow 8 or 8' and its geometric shape can be chosen as desired.
