Definitions

  • the present invention relates to a railway wagon equipped to replace both wooden and reinforced-concrete sleepers along tracks.
  • the wagon in question is intended to be used to replace sleepers which are no longer suitable, with other new sleepers, without modifying the arrangement of the track.
  • a first system of the semi-manual type and a second system which uses a railway wagon provided with an apparatus for handling the sleepers.
  • the first system of the semi-manual type envisages, as is known, that displacement of the sleepers outside of the track and removal of part of the ballast are performed with grab-bucket mechanical means, while extraction and reinsertion of the sleepers as well as preparation of the support surface for the new sleepers are performed manually by the operators who use, for this purpose, forks, shovels and rakes.
  • the operations performed by means of this first semi-manual system of the known type requires a considerable amount of time which in some cases, where there is a large number of sleepers to be replaced, results in the decision to close off the track completely, with demolition and subsequent reconstruction thereof. This obviously causes major disruption of the rail traffic.
  • the second system of the known type is described in Italian patent of industrial invention No. 01253254.
  • the apparatus mentioned above basically comprises an articulated arm mounted on the railway wagon and provided at its free end with a gripper for respectively extracting the sleepers from underneath and inserting them under the tracks.
  • a pair of movable hook-irons are also provided for displacing the ballast from the railway bed and forming the seats for the sleepers to be inserted underneath the tracks.
  • the new sleepers which are to replace those sleepers along the track which are no longer suitable must be positioned beforehand along the railway line itself in a position suitable for allowing gripping thereof by the articulated arm. This operation requires a considerable amount of time which negatively influences the time needed for replacement of the sleepers.
  • the main object of the present invention is therefore that of overcoming the drawbacks associated with the systems of the known type, by providing a railway wagon equipped to replace sleepers along tracks, allowing automatic replacement of the sleepers which are no longer suitable, with other new ones.
  • a further object of the present invention is that of providing a railway wagon equipped to replace sleepers, which is constructionally simple and operational entirely reliable.
  • the railway wagon in question which essentially comprises an articulated arm fixed at one of its ends to the railway wagon and provided at its free end with a gripper device for gripping individually the sleepers and extracting them from underneath a railway track or inserting them under it.
  • the railway wagon in question is characterized by the fact that it comprises a store for a plurality of sleepers, which is arranged on top of the railway wagon, and handling means designed to transfer the individual sleepers from the store to a pick-up position, from where the articulated arm can be operated so as to pick up each individual sleeper and insert it underneath the railway track.
  • 1 denotes in its entirety the railway wagon equipped to replace sleepers along tracks according to the present invention.
  • Said wagon travels along the same track 2 where the sleepers 3 are to be replaced and for this purpose is motorised so that it is able to peform in a completely autonomous manner the necessary movements along the railway line.
  • the equipment provided for replacement of the sleepers 3 is fixed at the front of the railway wagon 1 (see Figs. 1 and 2).
  • the railway wagon in question has, in its front part 4, an articulated arm 5 which is fixed at one of its ends to the railway wagon 1 and provided at its free end with a gripper device 6 (see Fig. 6) which is designed to grip individually the sleepers 3 and extract them from underneath the railway track 2 or insert them under it.
  • the central part 7 and rear part 8 of the wagon 1 are provided internally with a store 9 which houses a plurality of sleepers 3 arranged on several parallel shelves 10.
  • Handling means 13, 15, 17 are also provided on top of the railway wagon 1, for transferring the individual sleepers 3 from the store 9 to a pick-up position 12.
  • the articulated arm 5 is able to rotate about a vertical axis A and pick up, by means of operation of a plurality of mechanical actuators (indicated by 50, 51, 52, 53 and 54 in Fig. 6)), the individual sleepers 3 from the pick-up position 12 and insert them underneath the track 2.
  • a plurality of mechanical actuators indicated by 50, 51, 52, 53 and 54 in Fig. 6
  • the pick-up position 12 of the sleeper 3 is offset perpendicularly with respect to the track 2 towards one side of the railway wagon 1. This is so as to allow easy gripping of the sleepers 3 by the gripper device 6 mounted on the articulated arm 5.
  • the handling means comprise transportation means 13 for picking up the sleepers from the store 9 and conveying them as far as a first transit position 14, elevator means 15 for transferring the sleepers 3 from the first transit position 14 to a second transit position 16, and positioning means 17 which are able to displace the sleepers perpendicularly with respect to the track and thus convey them from the second transit position 16 to the abovementioned pick-up position 12 (see Fig. 3).
  • the transportation means 13 in turn consist of a bridge crane 18 (see Fig. 5) mounted above the store 9 and feeding means 19 which receive the sleepers 3 from the bridge crane 18 (preferably in groups formed by several sleepers 3) and move them forwards in successive steps as far as the first transit position 14.
  • the bridge crane 18 is motorised and is able to move along the whole of the main extension of the store 9 owing to a rack 60 with which it meshes by means of a pair of gear wheels 61 (see Fig. 1).
  • the elevator means 15 mentioned above consist (see Figs. 3 and 4) of a structure 20 provided with a receiving seat 21 and actuated by a second linear actuator 22 so as to move via special guides 23 between an upper position, where it receives, in the seat 21, a sleeper 3 supplied by the feeding means, and a lowered position, where it allows the positioning means 17 to bring the sleeper 3 arranged in the seat 21 into the pick-up position 12.
  • the feeding means 19 mentioned above comprise (see Fig.
  • a fixed frame 24 and a movable frame 25 which receives the movement from a pair of motorised cams 26 which impart to it a to-and-fro movement.
  • the movable frame 25 picks up the sleepers 3 from the fixed frame 24 and then deposits them again in a more advanced position of the fixed frame 24 in the direction of feeding of the means 19 (or towards the pick-up position 12).
  • the positioning means 17 comprise a pair of linear actuators (not shown in the accompanying figures) which are contained inside the box-shaped support structure of the receiving seat 21 and each of which is able to move, by means of the guides 70, a movable element 71 (see Figs. 4 and 7). The latter, when actuated by means of the corresponding linear actuator, is in turn able to push the sleeper 3 into the pick-up position 12 by means of a pawl 72.
  • the front part 4 of the railway wagon 1 is provided, in the vicinity of the articulated arm 5, with means 27 for displacing the ballast of the railway bed (not shown in the accompanying figures) and consequently providing a seat for the sleeper 3 to be inserted underneath the tracks 2.
  • These means 27 for displacing the ballast comprise, as shown in Fig. 3, a vertically movable structure 40 which is operated by a pair of hydraulic jacks 41 which are arranged vertically and a series of iron-hook pairs integral with the movable structure 40 and designed to penetrate into the ballast of the bed and displace it laterally.
  • Each of the iron hooks 42 is formed by an arm with a slightly curved bottom part which can be actuated by means of an operating lever 43 via a hydraulic jack 44.
  • the shelves 10 of sleepers 3 located inside the store 9 are arranged at a distance from one another by separation bars 28 (see Fig. 5).
  • the latter are connected to a surrounding frame 29 of the store 9 by means of a plurality of arms 30 which are movable (in the direction of the arrows indicated in Fig. 5) and designed to displace the separation bars 28 between a first position, where they support the sleepers 3 and are arranged between two successive shelves 10 of sleepers 3, and a second position, where they are arranged outside the sleepers 3 in the vicinity of the surrounding frame 29.
  • the separation bars 28 are displaced by means of the movable arms 30 into the second position behind the surrounding frame so as to allow the bridge crane 18 to remove a further lower shelf 10 of sleepers 3.
  • the railway wagon 1 according to the present invention which was described above from a mainly structural point of view, is able to operate as described hereinbelow.
  • the sleepers 3 are loaded onto the wagon 1 at the rear 8 thereof and are then arranged by means of the bridge crane 18 on different shelves 10 inside the store 9.
  • the railway wagon 1 is ready to perform replacement of the sleepers which are not suitable, with other new sleepers.
  • the bridge crane 18 transports in groups the sleepers 3 from the store 9 to the feeding means 19 which transport them as far as the first transit position 14, by means of the to-and-fro movement of the movable frame 25 with respect to the fixed frame 24.
  • detection means such as, for example, a photocell
  • the sleeper 3 is pushed perpendicularly with respect to the direction of the track 2 until it reaches the pick-up position 12 so as to allow subsequent easy gripping thereof by the gripper device 6 mounted on the articulated arm 5.
  • the means 27 for displacing the ballast of the railway bed and forming the seat designed to allow insertion of the sleeper 3 underneath the track 2 by the articulated arm 5 start to operate.
