Definitions

  • the present invention relates to machines and methods for the renovation of railways.
  • the invention relates to a railroad renovation set intended for the replacement of both rails and sleepers of a railroad generally in operation.
  • the railway is renovated in sections because this renovation is carried out for short periods of time, typically at night, during which traffic is interrupted, and the railway has to be recirculated in a restrictive manner to a precise schedule.
  • Such machines have a great complexity, and the risk that a damage or failure occurs during the intervention of the machine on the track can unfortunately not be completely avoided; if such an eventuality occurs, it is very difficult that companions can intervene under the machine to ask sleepers and rails in troubleshooting solution to allow the resumption of traffic as soon as possible, preferably in time.
  • the two trains can also be discarded to facilitate the journeyman's intervention in the lane area to be restored.
  • the risk of non-return to the operational circulation at the end of the period of time allotted for the works is consequently reduced, compared to the case of a machine that spans the renovation zone.
  • the first train includes a tool for removing the sleepers, additional wagons for storing the sleepers deposited, at least one shuttle gantry rolling on the wagons, with handling means. So that this equipment allows to continuously process the removal of old sleepers and their storage on the landing gear.
  • baskets are used to contain the deposited sleepers, baskets and handling means being configured so that the sleepers are generally parallel to the transverse direction (T) to the track, without exceeding the template; whereby the used sleepers are stored securely, without risk for subsequent transport; it thus proposes a simple handling of the used sleepers, without rotation of the sleepers, and without exceeding template relative to the adjacent channel.
  • Each of the baskets comprises transverse slats with at least two vertical recesses for the passage of the forks of the handling means in the axial and vertical directions; whereby the baskets form very simple structures, without moving part (s), moreover it is not necessary to strap the sleepers for the subsequent circulation.
  • the support leg is a motorized track support leg; whereby each of the removal and installation trains can carry out renovation operations independently without locomotive tractor and without motorized bogie.
  • the second train comprises a tool for laying sleepers, additional wagons for storing the new sleepers, at least one gantry-shuttle rolling on the wagons, with handling means. So that this equipment makes it possible to store the new sleepers in waiting on the laying train and allows to continuously process the installation of new sleepers.
  • the first and second trains can operate with a distance (D1) of reduced separation, less than 2 m, so that in the construction zone (Z), the zone without crosspieces (Z1) has a length of less than 15 m and the zone without laid rails (Z2) has a length of less than 40 m; whereby the length of track deposited is small, and in case of failure of the machine, the manual installation of a portion of track to connect the old way to the new requires only a limited time.
  • D1 of reduced separation less than 2 m
  • An optical guiding device can be provided between the front end of the gantry of the second train and the forward end of the gantry of the first train, whereby the retrofit assembly can rest the new track exactly at the deposited track location. , even in case of curve.
  • the two trains can be coupled in a standard manner, so as to be evacuated together in a convoy from the construction site area.
  • the purpose of the invention is also to propose a basket for receiving used railway sleepers, specially designed with transverse slats having two vertical recesses for the passage of the forks of the handling means in the axial directions (L) and vertical.
  • the figure 1 represents the renovation set according to the invention, such a railroad renovation set is intended for the replacement of both rails and sleepers of a railroad generally in operation.
  • the railway in question generally extends in a longitudinal direction L , the transverse direction T being defined as the perpendicular horizontal to this longitudinal direction.
  • ballast needs to be refurbished, this can be done in advance regardless of the removal and reinstallation of the track that is described here.
  • the laying train 1 and the laying train 2 are separate, working close to each other, on both sides of a construction site Z zone of renovation.
  • the Z worksite area in question comprises a zone without cross members Z1 and a zone without rails Z2 placed, zone longer than the previous one.
  • the zone without crosspieces Z1 has a length of less than 15 m and the zone without rails Z2 has a length less than 40 m.
  • Each of the first and second trains 1,2 comprises a flat car 5 with conventional bogies 50 and a telescopic gantry 3 .
  • Said telescopic gantry 3 comprises a rigid mechanically welded mechanical assembly 34 , with front rolling means 35 and rear rolling means 36 provided for rolling on on-board rails 58 on the flat car.
  • said telescopic gantry 3 is designed to rest on the flat car 5 and on a support leg 4 crawler, vertically movable, said support leg being part of the equipment of the telescopic gantry, at its front beam 33 .
  • the track is a motorized track 40 , intended to advance the respective train during the laying and / or removal operations.
  • the caterpillar could be a passive caterpillar and the train could be driven by a conventional bogie equipped with motorization, or a locomotives (the one who brought the train for example).
  • a device for controlling the direction of advance (orientation) of the track relative to the telescopic gantry is preferably provided.
  • the powered crawler device may comprise two separate caterpillars, namely a right caterpillar and a left caterpillar.
  • the steering control can result from a differential control between the left track and the right track.
  • the support leg 4 is movable vertically between a working position resting on the ground and a storage position on the car 5 . In working position, the height is adjustable by means of a hydraulic cylinder 42 .
  • the support leg of the landing gear comprises a harrow 41 (also known as claws) to break the coherence of the ballast.
  • the telescopic gantry 3 is movable longitudinally between a working position (as illustrated in FIGS. Figures 1 to 3 ) and a storage position ( Fig 4A and 8 ), where the gantry is entirely positioned above the flat car 5.
  • the two trains can be coupled in a standard way, so as to be brought together and evacuated together in a convoy from the construction zone ( Fig 8 ).
  • the convoy formed by the first and second trains 1,2 is routed, through a locomotive or a locomotives (preferably one at each end), to the site area at the junction of the new and old tracks, ie where the renovation project was interrupted during the previous intervention.
  • the laying train is uncoupled from the laying train, and we proceed to the operation of the site of each of the trains, starting with the landing gear.
  • the telescopic gantry 3 is advanced towards the free end of the train, a distance slightly greater than the length of the tracks.
  • the front wheels 35 of the telescopic gantry are then at the edge of the front end 55 of the flat car. Then we move the support leg 4 down for it to come wear on the ballast ( Fig 4B ).
  • the cars 5.15 of the train are moved while the telescopic gantry remains stationary, until the rear wheels 36 of the telescopic gantry 3 are in the vicinity of the end. before 55 free of the flat wagon 5 at the head of the train ( Fig 4C ).
  • the motorized track 40 is the means of movement (progression) of the train along the track from the moment it is supported on the ballast.
  • the landing gear 1 When the landing gear 1 begins to operate and advances (arrow F ), it frees up space on the ballast without rail or cross, so that the landing gear 2 can be put into operation, after having advanced a few meters so as to be able to put its motorized track directly on the ballast.
  • the front end 31 of the gantry 3 of the first gear 1 is separated from the front end 32 of the gantry of the second gear 2 by a distance denoted D1 ; this distance D1 can be short at the beginning of the worksite, preferably lower at 2 m, or even less than 1 m.
  • this distance D1 may be greater, however it is desirable that it remains relatively small, preferably less than a few meters; this distance D1 will be reduced again as much as possible near the time limit, preferably less than 2 m, or even less than 1 m, to restore the way to traffic.
  • the renovation assembly progresses along the longitudinal direction L of the track, the landing gear 1 preceding the laying train 2 , with independent control thanks to the motorized tracks.
  • the landing gear 1 comprises, in addition to the telescopic gantry 3 and the flat head wagon 5 already mentioned, complementary wagons 15 for storing the deposited sleepers 7a, and a gantry-shuttle 12 rolling on the wagons with handling means.
  • a tool 9 removal sleepers The tooling includes a pulling chain 91 of the sleepers, provided with teeth, a recovery conveyor 92 , and a fork manipulator 93 .
  • the sampling line raises the sleepers and deposits them one by one on the recovery conveyor 92.
  • the fork manipulator 93 has two forks 94 which extend in the longitudinal direction L; the fork manipulator 93 is configured to deposit the used sleepers 7a in baskets 8 which form containers for containing the used sleepers.
  • the fork manipulator 93 takes a group of sleepers (7 in the illustrated example) from the recovery conveyor 92 , and transports them to deposit them in a storage basket 8 used sleepers.
  • the baskets in question are specially designed with transverse side panels 81 (parallel to T) and longitudinal side panels 82 (parallel to L).
  • the transverse side walls 81 comprise two vertical recesses 83 for the passage of the forks 94 in the axial directions L and vertical.
  • the two transverse side panels 81 each have two vertical recesses 83 , which allows manipulator forks (or forklift) to intervene from one side or from the other side.
  • Shims 85 are also provided for laying the lower level of the sleepers for the passage and withdrawal of the forks. Wooden blocks are also provided between the different layers of sleepers that are stored in the basket 8 .
  • the baskets in question do not exceed the standard circulation gauge; therefore the receiving baskets of used sleepers keep a constant orientation, without rotation.
  • the aforementioned shuttle gantry 12 rolling equipped with handling means evacuates the full basket to a position further away from the front end 55 of the train, and supplies another empty basket 8 for the continuation of the removal operations, and so on.
  • the sleepers 7a being stored in baskets with sideboards, the convoy once reformed at the end of the intervention sequence, can travel safely without the risk of falling sleepers.
  • reception baskets 8 are particularly simple, without moving parts or hood to fold, they have a relatively simple structure and are very robust and enduring.
  • the laying train 2 comprises, in addition to the telescopic gantry 3 and the above-mentioned flat head wagon 5 , complementary wagons 15 for supplying new sleepers 7b , and a gantry-shuttle 12 rolling on the wagons with means of support. handling.
  • the new sleepers 7b can be arranged in batches on pallets or directly on a treadmill. They are deposited on the ballast as and by measure tooling 10 , known per se, and therefore not described in detail here.
  • the gantry proceeds, thanks to the guide arms (not shown, but known in itself), the laying of the new rails 6b , then to the installation of the fasteners that fix the rails relative to the sleepers .
  • the bogies 50 of the laying train 2 roll on a set path and attached.
  • the gantry of the laying train 2 also includes a tool for installing the fasteners or screws lag screw (not shown).
  • the motorized track support leg of the landing gear comprises a shield / blade 46 for leveling the ballast, and a tamping means 47 , arranged between the motorized track and the position of the depositing tool 10 .
  • the mechanical connection between the telescopic gantry 3 and the flat head wagon 5 has a degree of freedom of rotation of vertical axis A1.
  • the telescopic gantry is also provided and the head flat car has a degree of freedom of rotation with a vertical axis A2 .
  • the dropping train stops its operations.
  • the train of pose continues to join him in order to minimize the distance D1 which separates their respective ends before 31,32 .
  • the telescopic gantries 3 are retracted on either side of their respective flat cars 5 by pushing the respective locotractors located at the remote ends of the laying trains and removing them. Then we proceed to the lifting of the support leg 4 , and finally we proceed to the complete folding of each telescopic gantry 3 so that it is found entirely above the head wagon (that is to say the rear wheels 36 to near the rear end 56 ).
  • the laying and removal trains can be evacuated separately, or they can be coupled to form a single convoy to be evacuated ( Fig 8 ).
  • a proximity sensor device 61 between the front ends of the two trains to avoid buffering.
  • a visual and audible warning can warn from a distance D1 too low; it is also possible to provide an intervention on the motorization means of the tracks.
  • an optical guiding device 62 , 63 is provided so that the front end 32 of the The rest-train may be guided laterally so that the new track is laid exactly where the old track was, for both the straight and curved sections.
