Definitions

  • This invention comprises railway track tamping units which are displaceable in height and comprise pairs of tools working in opposition, are arranged on either side of the same line of rails and that the height displacement of each of them is controlled by an independent mechanical member having one of its ends articulated to a fixed support of the machine chassis and the other end displaceable at least transversally to the railway track axis.
  • the present invention relates to machines for tamping railway track ballast comprising pairs of vibrating tools mounted on displaceable chassis in height.
  • the movable chassis are generally equipped with at least two pairs of tamping tools operating one on each side of a line of rails and only able to penetrate the ballast together.
  • the machine forming the object of the invention aims at always tamping with tools working in opposition, whatever obstacle the track equipment offers.
  • This machine is characterised in that tamping units, which are displaceable in height and comprise pairs of tools working in opposition, are arranged on either side of the same line of rails and that the height displacement of each of them is controlled by an independent mechanical member having one of its ends articulated to a fixed support of the machine chassis and the other end displaceable at least transversally to the railway track axis.
  • the mechanical member controlling the height displacement of each unit is a rectilinear guide on which the unit slides, the upper end of said guide being articulated about a shaft which is substantially parallel to the track axis and the lower end slides in a horizontal slide fixed to the machine chassis and perpendicular to the track.
  • the guides of the units are articulated by their upper end about the two shafts which are preferably perpendicular to one another, the one being parallel to the track and the other transverse to the track.
  • the attached drawing shows as a non-limitative example, a machine for tamping the ballast of railway tracks, equipped with means in accordance with the preferred embodiment according to the invention wherein the tamping units can move both transversely and longitudinally to the track.
  • FIG. 1 is a side elevation limited to the part which is useful for clarity of description
  • FIG. 2 is a half front view showing the arrangement of the tamping units on either side of a line of rails
  • FIG. 3 is a sectional plan view on line A-A of FIG. 2
  • FIG. 4 is a part view of FIG. 1 showing a variant of the upper articulation of the guides of the units permitting their translation on this articulation in a direction longitudinal to the track.
  • FIG. 1 shows a tamping unit 5 comprising a pair of tools 6, 6 functioning in opposition in a known manner, said unit being displaceable in height by means of a hydraulic jack 7 and whereof the displacement is controlled by a rectilinear guide 4 on which it is slidingly mounted by means of a cutaway bearing 8, which guide is connected at its upper end to the chassis in the overhang 2 of the machine by a double articulation 3 and the lower end of which here in the shape of a ball 9, slides in a transverse slide 10, the U section of which is shown batched in the drawing.
  • the double articulation 3 comprises two perpendicular shafts 11 and 12 connected via an intermediate member 13.
  • the shaft 12 is supported by a cap 14 fixed to the chassis 2 of the machine and on the shaft 11, disposed in a plane substantially parallel to the line of rails 18 is articulated the guide 4 of the unit.
  • the hydraulic jack 7 is connected to the chassis 2 of the machine by a double articulation 15 of the same type and having the same functions as 3 described above.
  • the guide 4 which mechanically controls the height displacement of the unit 5 comprises a rectilinear column 16 and a bar 17 parallel to said column.
  • This bar 17 is connected via its ends to the column 16 via supports 19 and 20 and has the function of preventing the bearings of the unit from revolving round the column 16.
  • this bar 17 is articulated by its upper end about the shaft 11 of the double articulation 3.
  • unit 5 and guide 4 comprise an assembly articulated about the shaft 11 and capable of being inclined transversely to the track, as can be seen in FIG. 2.
  • FIG. 2 can be seen the arrangement of the units forming with their respective guides independent tamping systems each located on one side of a line of rails.
  • these systems are identical to those described hitherto, the reference numerals of the different component parts have in both this figure and FIG. 2 only been indicated on one of them.
  • This slide is articulated on the axis XX of the machine, by a cutaway bearing 21, about a vertical shaft 22 carried by a bracket 23 of machine 1. On either side of this axis the slide 10 is supported freely on another bracket 24.
  • each guide 4 The transverse slope to the track of each guide 4 is obtained and controlled by a hydraulic jack 26 supported on the slide 10 itself and acting on the lower support of the bar 17 (FIGS. 1 and 3) ofeach ofthe guides.
  • FIG. 4 can be seen the variant of the upper articulation of the guides of the units permitting their translational movement on said articulation in the longitudinal direction of the track.
  • This crossbeam 30 is articulated at its ends by two vertical bearings 31 and 32 to two fixed shafts 33 and 34 aligned in a plane substantially parallel to the track axis.
  • Each of these two shafts 33 and 34 is held by two spaced supports (35 and 36 for shaft 33, and 37 and 38 for shaft 34) rigidly connected to the machine chassis 2, thus permitting the displacement on these shafts of the bearings 31 and 32 of crossbeam 30.
  • the space between these supports is defined by the maximum desired displacement of the units in the longitudinal plane.
  • a hydraulic jack 39 supported on support 36 and connected to the crossbeam 30 via a bearing 40 rigidly connected with this crossbeam.
  • Each unit can therefore be displaced longitudinally tothe. track by using this jack.
  • each lower end of the guides of the units can be moved transversally to the track, either by means of a transverse jack mounted on rollers and supported on the machine chassis, or as shown in FIGS. 1, 2 and 3 by a jack supported on an articulated slide 10 which would rotate freely and the drive jack 25 being eliminated.
  • hydraulic jack 7 could be supported on the support 19 which'is rigidly connected to the guide 16-17 and act on the bearing 8 of the unit.
  • the ball 9 could be replaced by an articulated shoe.
  • a machine for tamping railway track ballast which includes a chassis with fixed supports and at least two height-displaceable tamping units with pairs of tools mounted on said units; the improvement which comprises: a first articulated coupling for securing said tamping units to the chassis for operation on both sides of either track rail, a guide member also secured to the chassis at the upper end of the guide member by a second articulated coupling for guiding the tamping units as they are lowered to the track ballast, said guide member including a rod disposed within a sliding bearing, the lower end of said rod being slidably mounted in a channel positioned perpendicular to the rails, and said bearing secured to the tamping units.
  • a machine according to claim 1 wherein a first hydraulic jack is mounted between the first articulated coupling and the tamping tool for moving both the tamping tool and the bearing on the guide rod.
  • a machine for tamping railway track ballast comprising a chassis with fixed supports, two height-displaceable tamping units on which are mounted pairs of tools working in opposition, said units being arranged on either side of the same line of rails, a guide member coupled to the tamping units and secured to the chassis at its upper end by a second articulated coupling for guiding the tamping units in a rectilinear direction, said guide member including a rod, the lower end of which is slidably mounted in a channel for movement in a direction transverse to the rails.
