Definitions

  • the invention generally relates to a rail vehicle and method for installation and removal of railroad crossties or sleepers.
  • a tie exchanging apparatus extracts and loads old ties, and unloads and installs new ties.
  • the apparatus comprises at least one tie distribution car, a tie collection car and a storage car, each having interconnected guide rails bridging between cars, permitting a tie loading vehicle and a tie transport vehicle to move from car to car.
  • the tie loading vehicle transfers ties from the storage cars to a storage basket which is structured to fit removably in a gondola car for temporarily holding a number of ties.
  • the transport vehicle engages the basket and transfers it over the guide rails to an active location along on the tie exchanging vehicle where the ties are unloaded and distributed or collected for storage.
  • Rails comprise a bed of ballast material, such as size four stones, in which ties are embedded and support rails laid thereupon at a specific gauge width.
  • the rails are set on tie plates and fastened to the ties by anchors and spikes, clips or the like.
  • rail ties are usually made of wood or a similar material that absorbs shock as trains pass, although concrete ties are also used.
  • the rails are subjected to compressive and shearing forces that tend to loosen the spikes and anchors from the ties over time.
  • Wooden ties also weather, becoming dry and brittle. Eventually, ties fatigue and fracture under the stresses imposed, and accordingly it is necessary to replace the ties regularly. All the ties along a section of the railway may be changed, or only selected ties.
  • railway ties are usually replaced using a multi-car apparatus that replaces ties on a section of track as it travels over that section.
  • Specialized rail cars have tie removal machinery and means to remove, unload and install ties.
  • worn ties that are removed are exchanged with newly installed ties, rather then being left along the track for later collection.

  • a load-straddling gantry crane is movable on guide rail sections that bridge between the tie storage cars for moving groups of stacked ties. The cranes are used for manipulating old and new ties in conjunction with tie pullers and inserters, conveyors and storage areas for the old and new ties.

  • Theurer discloses an integrated tie replacement system, it would be advantageous to improve the efficiency of storage and transportation of the ties.
  • Theurer utilizes open flat cars with upright supports which abut longitudinally against stacks of laterally extending ties. This is a compact arrangement for new ties, but old ties often are broken or splintered and do not stack in an organized manner. Old ties need a container or the like that is sufficiently closed to contain splintered ties and shards, but which nevertheless is readily accessible and can be fully loaded.
  • the span of the Theurer gantry crane that is movable atop flatbed cars for transporting ties limits the number of ties that can be engaged.

  • the full range of motion for the parallelogram linkage 234 and the outer beam 226 is illustrated in Figs. 16-20 and Figs. 21-25.
  • beam 226 is retracted within support tube 208 and parallelogram linkage 234 is rotated so that clamp assembly 240 is aligned with the end of a tie 14.
  • Clamp assembly 240 grips tie 14 and beam 226 is moved in an outward direction from support tube 208 pulling tie 14 from underneath the rails 18.
  • Parallelogram linkage 234 is then rotated to raise tie 14 to the height of the first level 114A of the combined car 100 (FIG. 2) .
  • the outer beam 226 is retracted during or after rotation, and the clamp assembly 240 opens to release tie 14 on tie collecting conveyor 108, on the first level 114A of combined car 100.
  • tie transporter pick-up collected worn ties 14 from compartment 106 and transport them for storage in old tie storage car 60.

Abstract

L'invention concerne un véhicule (10) d'entretien de voies ferrées servant à remplacer des traverses (14) usées par des nouvelles (16). Des traverses (14) usées sont ramassées et stockées dans des wagons-tombereaux (60, 62) découverts, avançant de préférence longitudinalement. De nouvelles traverses (16) sont déchargées simultanément des wagons-tombereaux (60, 62) pour être réparties le long de la voie (18). Des véhicules (34, 48A, 48B) de transport de traverses à boudin de roue, tels qu'un transport de grue mobile et de pince à paquets, se déplacent sur des rails (34) situés au sommet des wagons-tombereaux (60, 62) afin de déplacer des traverses usées (14) et de nouvelles (16) traverses entre des dispositifs (20, 40) de ramassage et de répartition et les emplacements respectifs de stockage et de déchargement. Les espaces entre les wagons sont pontés par des sections (36) de rails télescopiques suspendus. La distance de déplacement entre l'emplacement de stockage ou de déchargement et les postes de ramassage ou de répartition change avec le temps. Pour améliorer l'efficacité du système, au moins une corbeille (50) de stockage temporaire intermédiaire est déplacée le long des wagons (60, 62), les véhicules (38, 48A, 48B) pouvant passer sur celle-ci. La corbeille (50) est utilisée de préférence avec un troisième véhicule (38) de transport de traverses pour contribuer à la manipulation des paquets et raccourcir le déplacement du premier (48A) ou du deuxième (48B) transport de ramassage ou de distribution. La corbeille (50) est particulièrement utile pour accumuler un paquet de nouvelles traverses (16) en vue d'un ramassage par un véhicule (38) de transport de préhension de paquets. Le véhicule (10) peut être limité au ramassage et au stockage de traverses (14) usées laissées sur les rails (18) par un extracteur (200) de traverses précédent, et au déchargement de nouvelles traverses (16), ou peut également incorporer des dispositifs (200) d'extraction et/ou d'insertion de traverses.
