Definitions

  • the present invention relates to railway ballast tamping machines adapted to travel along a railroad track from tie to tie to tamp the ballast under each tie.
  • pairs of tamping tools are mounted on a vertically movable carrier so that the ends of the tools enters into the ballast in the operating position of the carrier.
  • Efiicient tamping machines have been built with a plurality of pairs of cooperating tamping tools mounted on separate carriers to tamp the ballast under the ties about each rail. After tamping with these conventional machines, individual dense ballast zones were formed where the rails crossed the ties while the remainder of the ties, particularly the tie ends, rested on relatively loose ballast and were, therefore, insufliciently supported.
  • the track tamping machine may be provided exclusively with laterally mounted tamping tools arranged to cooperate with the tie ends.
  • the laterally mounted tools are provided in addition to the conventional tamping tool aggregates which tamp the ballast about each rail in a direction longitudinal with respect to the track.
  • each such tamping tool aggregate comprises at least one pair of atent cooperating tamping tools which tamp the ballast in a longitudinal direction, and at least one lateral tamping tool which tamps the ballast laterally from the end toward the center of the tie.
  • This arrangement prevents the displacement of the ballast during tamping into the space between the ties. It provides a tamped ballast zone of U shape about the ends of the ties and extending toward their center so that each tie rests on both ends on a wide and solid support, and the tie pressure is distributed over a relatively large area.
  • not all tamping tools of each aggregate need be mobile, i.e. active. Rather, either the longitudinally or the laterally effective tools may be fixedly mounted on the vertically movable tamping tool carrier so that it will remain stationary during the tamping operation.
  • the stationary tool or tools When the tamping tools are lowered into the ballast, the stationary tool or tools will form a barrier wall which will passively cooperate with the mobile or active tools in the tamping operation.
  • At least one of the tools must be mobile, of course, and if the machine carries only a laterally arranged end tool for tamping the tie ends, the lateral end tool must be mobile.
  • FIG. 1 is a side view of one embodiment of a tamping tool aggregate in accordance with the invention
  • Fig. 2 is a front view of the aggregate of Fig. 1;
  • Fig. 3 is a side view of another tamping tool aggregate
  • Fig. 4 is a front view of the aggregate of Fig. 2;
  • Fig. 5 is a side view of still another tamping tool aggregate
  • Fig. 6 is a front view of the aggregate of Fig. 5;
  • Figs. 7, 8, and 9 are schematic views illustrating the operation of the three above embodiments.
  • the jaw ends 9 of the tamping tools 6 penetrate into ballast 14 along the longitudinal sides of the ties 13 and tamp or density the ballast therebetween when they are moved together while being vibrated during the tamping operation, thus tamping the ballast under the tie in the range of rail 12.
  • the ballast bed is shown spread over base 15.
  • a lateral plate 10 fixedly mounted on tamping tool carrier'3 by means of bracket 11.
  • the plate 10 extends parallel to the end face of tie 13 and, as will appear clearly from Figs. 2 and 7, the plate 10 will form a barrier wall preventing ballast frombeing displaced laterally outwardly while tamping tools '6 are moved together during tamping. This will result in the densest ballast immediately underneath the tie ends and, more generally, within the U-shaped area bounded by tamping tools 6 and barrier plate 10.
  • the stationary barrier plate 10 is replaced by movable tamping tools 6.
  • the tamping tools 6' are mounted like tamping tools 6, being also vibrated by rotation of an eccentric shaft 4 which carries the tool support arms 5.
  • the lateral tamping tools 6 are also pivoted to the support arms at ,7 and are movable together and apart by means of a mechanism 8' of any conventional design.
  • the entire structure is equivalent to the mounting of tampingtools 6, except that the jaws 9' of the tools tamp in the direction of the ties '13, instead of transversely thereto.
  • the tamper is again suspended over the tie to be tamped on the forward portion of the track tamping machine which moves on wheels 1' over rails 12.
  • the operation of the tamper is illustrated in Fig. 8 where the arrows indicate the movement of the tamping tools, as in Fig. 7.
  • the tamping of the ballast will provide a solid support for the'tie 13, not only in the range of the rail 12, but also atits end and well toward the center of the tie in a generally U-shaped area around each tie end.
  • the outer or lateral tamping tools 6' are mobile, as in the embodiment of Figs. 3 and 4, while the inner tamping tools 10 are fixedly mounted on the tamping tool carrier 3 and extend parallel to the longitudinal faces of the tie 13 on each side thereof.
  • the tamping tools 10 are mounted on the carrier by brackets 11' and form barrier walls similar to barrier wall 10, except that these barriers will prevent longitudinal displacement of the ballast in the direction of the track when movable tamping tools 6' are moved inwardly to tamp the ballast.
  • the operation of the machine is schematically shown in Fig. 9.
  • the longitudinal barriers 10 could be omitted whereby the ballast under the ends of the ties would still be effectively tamped by operation of the movable tamping tools 6'.
  • a mobile ballast tamping machine adapted to travel along the rails of a railroad track mounted on ties, comprising a vertically adjustable tamping tool carrier which may be lowered into a tamping position, at least one pair of cooperating tamping tools mounted on the carrier -so that eachtool of the cooperating pair is positioned alongside the longitudinal'sides of a tie to be tamped and in proximityof one of said rails when the carrier has been lowered'into the tamping position, flat jaws at the ends of the cooperating tamping tools and extending in the same direction as said longitudinal tie sides, and at least one additional tamping tool mounted on the carrier symmetrically with respect of said pair of cooperating tamping tools and laterally outside the end ofthe said tie, said additional tamping tool having a flat jaw extending transversely of the longitudinal tie sides.
  • the cooperating tamping tools are mounted for mutually approaching movement in direction of the track and the additional tamping tool is a fixed flat member extending in said direction.
  • the cooperating tamping tools are mounted for mutually approaching movement in direction of the track and'the additional tamping tool is mounted for movement in a direction perpendicular to the direction of movement of the cooperating tamping tools.
