  • FIGS 19 and 20 illustrate alternative apparatus in accordance with the invention.
  • FIGS 21 and 22 illustrate still further alternative apparatus in accordance with the invention.
  • the apparatus illustrated in Figures 1 to 3 comprises a dispenser for enabling steel railway sleepers to be laid at regular intervals onto a track bed with no or very limited down-force which would otherwise disturb the bed surface and possibly cause misalignment of the sleeper from its intended position.
  • sleepers are discharged from dispensing equipment at a height above the track bed.
  • the illustrated apparatus is supported on a vehicle (not shown) movable in the direction of arrow A.
  • the speed of the vehicle is preferably such that the residence time of the vehicle at the position at which a sleeper is to be laid is minimised.
  • the apparatus comprises a main frame 1 including a pair of uprights pillar 2 each including a generally horizontal upper support arm 3 from which are suspended two swinging arms 4 movable about pivots 5 by which the swinging arms are connected to the frame.
  • Sideways movements of the swinging arms 4 is effected and controlled through hydraulic, pneumatic or like cylinders 6 whose pistons 7 are connected by rods 8 to linkages 9 positioned at the lower ends of the swinging arms 4.
  • Each arm 4 is formed with an inwardly extending lower ridge 11.
  • These ridges together provide support for a vertical stack of railways sleepers 12 separated by spacers 13 and positioned between side guides 10.
  • the spacers 13 are not secured to the sleepers and merely act to space a sleeper from neighbouring sleepers to prevent damage to rail clip devices carried by the sleepers.
  • the apparatus includes a lifting frame 14 comprising a pair of pillars movable vertically by means of a hydraulic, pneumatic or like cylinder and connection rod 19, 20 respectively.
  • Lifting arms 17 are mounted for pivotal movement from brackets 18 secured to inwardly facing upper surfaces of the frame members 14. The lifting arms are movable towards and away from the lifting frame by hydraulic, pneumatic or like cylinders 15 and interconnecting rods 16.
  • Each lifting arm 17 is formed at its lower end with inwardly extending support ledges 21.
  • the side faces of the ledges are chamfered.
  • the lifting arms are moved downwardly to a position close to the track bed surface.
  • the arms are moved outwardly to enable the sleeper walls to enter the space defined between the lifting arms and to be engaged by the chamfered side surfaces of the arms.
  • This position is shown in Figure 3.
  • the ledges 21 include vacuum or magnetic gripper pads 23.
  • the sleeper is then gently moved into contact with the surface of the track bed in its required position.
  • the handling apparatus is then moved by the support vehicle to the next location immediately above the intended site of the next sleeper. The process described above is then repeated.
  • a magnetic sweeper 24 may be passed over the upper surface of a steel sleeper to remove any debris and/or the spacer 13.
  • the dispensing apparatus illustrated in Figures 4 and 5 differs from that described above essentially in relation to the way in which the sleepers are conveyed from the vertical stack to the track bed.
  • the lowermost sleeper of the stack is placed by the swinging arms 4 onto a vertically movable stand 30 which is then lowered by a hydraulic ram 31 to be received by a continuous chain conveyor 32 whose movement is linked to forward motion of the supporting vehicle.
  • Figure 4 shows the position of the apparatus as a sleeper is loaded onto the stand 30
  • Figure 5 shows the position of the apparatus with the stand retracted.
  • sleepers loaded onto the chain conveyor are sequentially moved by the conveyor to their required sites on the track bed. The height of the sleeper above ground level at the point at which sleepers leave the conveyer is minimal.
  • FIG. 6 shows the position of the apparatus with the lowermost steel sleeper supported by the ledges 21 and Figure 7 shows the position of the apparatus with the lifting arms 17 in their lowered positions.
  • Downward pivotal movement of the ledges 21 enables a steel sleeper to be gently lowered onto the track bed in the required position.
  • downward movement of the vertical stack of steel railway sleepers within the handling apparatus is achieved by means of a pair of spaced vertically disposed continuous chains 35.
  • Support ledges 36 carried by links of the chains cooperate to support the steel sleepers.
  • the lowermost ends of the chains are positioned just above ground level to minimise the height at which the sleepers are released onto the track bed.
  • the handling apparatus illustrated in Figures 9 to 11 comprises a vehicle mounted robotic arm 40 programmed to remove railway sleepers from vertical stacks carried by the vehicle 41 and to lay successive sleepers onto the track bed at discrete intervals determined by a laser setting unit 42, 43.
  • the sleeper handling arm 44 of the robot carries a magnet 45 for lifting and laying successive sleepers.
  • the vehicle 41 runs alongside the track bed 46 and the robotic arm 40 and laser setting unit ensure that succeeding sleepers are accurately spaced from one another with a minimum or no misalignment.
  • the vehicle is supported on caterpillar tracks 47.
  • the vehicle is in line with but in front of the track bed 46.
  • the sleeper carrying vehicle comprises a plurality of aligned grab devices 50 supported from a frame 51 which spans the track bed. At required intervals, lifting cylinders 52 connected to the grabs are operated at the same time to enable a plurality of railway sleepers to be laid simultaneously onto the track bed in their correct positions. As shown, eight sleepers are laid simultaneously. As for the vehicle of Figures 9 to 11, the vehicle 41 is supported on caterpillar tracks 47. As shown in Figure 14, the grab devices are reloaded from sleeper stacks positioned remote from the sleeper laying activity.
  • the sleepers are stacked in a vertical sense.
  • the sleepers are stacked horizontally on their sides as shown in Figures 16 to 18,
  • the end sleeper is removed from the horizontal stack by means of a separating dog 56 and then laid onto the track bed using a robotic arm or chain conveyor as discussed previously.
  • steel sleepers may be moved from a sideways (on side) alignment to a Afoot down@ (on bead) alignment by:
  • Sleepers may be positioned into a distribution rack or may be laid directly onto the track bed using any of the methods discussed above, either from their original sideways positions or the horizontal positions attained by the alignment method discussed above.
  • Sleepers may also feed directly from their sideways positions into their correctly laid positions by transport on elongated dogs which cause rotation to a horizontal position at the end of the feed system. For example, by rotation on a chain around an end guide wheel.
  • Bundles of sleepers may be held between vertical stays, having been supplied originally as vertical or horizontal packs, to then be transferred by a "pick and place" robot.
  • Trailers or systems may be moved forward by either motor devices on the same carriage or moved by external vehicle.
  • the apparatus comprises a dispenser 60 for a stack of steel sleepers.
  • the dispenser includes swinging side walls 61 formed with inwardly protruding lips 62 which open to deposit the entire sleeper stack onto the track bed. The dispenser is then lifted and the side walls closed to lift from the lowermost sleeper the stack of other sleepers. The dispenser is then indexed a distance equal to the desired sleeper separation and the operation repeated.
  • the release mechanism may operate at or close to the surface of the track bed, or at a height above the track bed.
  • retractable arms 63 or another like gripping mechanism support the sleeper stack.
  • the arms may carry magnets or may apply vacuum to grip and release the entire sleeper stack or a part of this stack.
  • An important feature of the described invention is to retain control of the sleeper throughout its passage through the system thereby eliminating either uncontrolled dropping of sleepers or support systems which act on the sleeper underside and cannot control sleepers as they move onto track bed without disturbing the ballast content of the bed.
  • the motive force applied to the or each sleeper which controls passage or descent of the sleepers' positions onto the track bed through motorised elements which may be driven electrically, hydraulically, pneumatically or through the use of stored mechanical energy.
  • the former system may comprise simple elements with rudimentary control over motion or may consist of the use of highly sophisticated mechanical robots which takes sleepers from one of a number of locations and places directly or indirectly at the correct locations on the track bed.
