Definitions

  • the present invention relates to a train for renewing a railway track, consisting of at least one train of work wagons and wagons for the transport of new and old materials, allowing at one time, by replacement and recovery materials, to renew railway tracks made up of rails and sleepers with the possibility of carrying out simultaneously and continuously all the phases ensuring the substitution of the materials constituting the railway tracks, the ream of work wagons comprising a drop wagon, a wagon stripping, a laying wagon, a wagon, and transporters of spent ballast to a screening machine installed on a wagon placed outside the renewal area, transporters bringing the screened ballast to a storage and distribution silo comprising regulating means for the distribution of the screened ballast on the new track, as well as transporters of the sleepers, or the old spans and t new sleepers arranged above at least one of the ballast carriers.
  • the renewal of a railroad includes, in addition to the replacement of rails and sleepers, the renewal of the ballast, because an old ballast, soiled with detritus and clogged no longer has the required elasticity and permeability properties.
  • the successive additions of gravel during the operations of rectification and stuffing of the sleepers have the effect of raising the track, which has serious drawbacks mainly when passing engineering structures.
  • stripping-screening of ballast is normally done before or after laying the new track. The duration of this operation is therefore added to that of the other renewal operations.
  • defamation-screening requires the lifting of the whole track by means of powerful machines, at the risk of deforming the new rails. Since the machines for stripping and screening the ballast are very large machines, their implementation is accompanied by long and complicated operations, both as regards their starting up and as regards their stopping.
  • patent CH - A - 583 822 which relates to a process for the complete renewal of a railway track, in which the course of the operations of removing the old track, stripping the screening of the ballast and laying the new track operates in a single pass of the complete renewal train, provided for this purpose.
  • the same patent also includes a train for the complete renewal of a railway track, comprising, in addition to the wagons for transporting the rails, sleepers and fasteners, at least one laying and removal train equipped with gantries, and frame wagons, as known from patents CH - A - 549,692 and CH - A - 585,814 of the same holder.
  • said renewal train are incorporated bodies for stripping and transporting the ballast to a screen installed on a wagon placed outside the renewal area.
  • the patent FR - A - 1 303 437 describes a device for laying and / or removing railway tracks, which essentially comprises a machine equipped with a door arrow -overhang to lift the rails and a monorail for the installation and removal of sleepers.
  • the machine runs on the part of the track not yet disassembled, when it comes to removing a track, or on the part of track already mounted, when it comes to laying a track.
  • the monorail for laying and removing crosspieces is placed in the axis of the machine and makes it possible to take or deposit crosspieces on a longitudinal conveyor, but since the monorail is placed in the axis of the track, there is no there is no room at its sides for the passage of means of transport of the ballast.
  • Patent DE-A-2 023 931 describes a track renewal train which works continuously, but in which the screening installation is placed in the area of the stripping itself. As a result, the length of the track replacement zone is extended by a length equal to the length of the screening plant. This is very unfavorable especially in hilly countries where the length of the site must be limited as much as possible.
  • This machine evacuates the old material to the front, while the new material is brought in from behind the train. The screen is located in the middle of the machine, the trash can only be removed on the sides of the track which is a big drawback.
  • the document FR - A - 1 602 279 describes a train consisting of a train of wagons for the transport of new and old materials, making it possible at one time, by replacement and recovery of materials, to renew railway tracks made up of rails and of sleepers with the possibility of carrying out simultaneously and continuously all the phases ensuring the subs titution of materials constituting the railways.
  • This train comprises means of transporting the sleepers which are arranged above at least one of the means of transporting the ballast. During the removal operations, the old track is lifted with its cross members assembled. Then it is necessary to dismantle the sleepers before being able to evacuate them, from which it follows that the working rhythm is determined by the dismantling speed of the sleepers, which is a drawback.
  • the object of the present invention is to eliminate the drawbacks which have just been listed, while retaining the advantage of transporting the excavated ballast to a screen installed on a wagon placed outside the work area, and to propose a renewal train improved in such a way that the removal operations of the old sleepers and the old rails or old spans, the excavation of the worn ballast, its screening, the laying of the new ballast, the new sleepers and the new rails are carried out continuously and simultaneously during the uninterrupted advance of the train.
  • the main problem that had to be solved was how to superimpose the transport of the excavated ballast, the recovered ballast, and the old sleepers alone or mounted on rail spans, so as not to encroach on the authorized gauge.
  • the present invention provides a renewal train which achieves the aim stated by the fact that to allow continuous renewal during the advance of the train, a train of working wagons, known per se, comprising a deposit wagon, a stripping wagon and a laying wagon, fitted with transporters for the old sleepers or spans, arranged above at least one of the ballast transporters, the deposit wagon comprising an elevating system which allows either to lift the old sleepers by pivoting them around a vertical axis in order to orient them in the longitudinal direction of the train to pass them at least next to the spent ballast transporter and place them transversely to the train on the old sleepers transporter located at - above this worn ballast transporter, either to lift and turn the old sleepers or a full span on a curved plane trajectory whose axis is parallel to the track, the axis of the sleepers remaining in a plane substantially perpendicular to the direction of the train, during rotation to place said sleepers or said span on a means of transport of the old sleepers
  • the main advantage obtained thanks to this invention resides in the reduction of the length of the site because the screening is done outside the work area, the trash can be easily removed without involving the sides of the track, and that it is possible to lift the spans or crosspieces previously dismantled, to pass them next to the ballast transporters to place them on the transporters of sleepers or spans for their evacuation, without encroaching on the width of the template authorized.
  • the renewal train consists of six main elements, shown schematically in the figure 1, or a screener, not shown, a deposit wagon 5, a stripping wagon 6, a laying wagon 7, a wagon of drawing and a gantry with transport beam, not shown.
  • the screening machine and the wagon are normal wagons with two bogies.
  • the deposit wagon 5, the stripping wagon 6 and the laying wagon 7 constitute an articulated train fitted with six bogies 12 to 17 and two tracked chassis 11 and 11 '.
  • the screening machine and the first bogie 12 of the deposit wagon 5 roll on the old track 1.
  • the central part of the train rests on the two track chassis 11 and 11 'which roll respectively on the ballast and on the excavated bench, or on the screened ballast.
  • the rear bogie 17 of the laying wagon 7 as well as the dowelling wagon roll on the new track 4.
  • the deposit wagon 5, FIGS. 1 and 2 is supported at the front on a bogie 12 and at the rear on a tracked chassis 11.
  • the conveyors 18 for the excavated material consisting essentially of the spent ballast and, above, the conveyors 19 for the recovered and screened ballast.
  • the removal and transport of the old sleepers is carried out using a hydraulic picker 20, chain conveyors 21, and a lifting system 22.
  • roller clamps known per se and not shown, lift and move aside the old rails 1 which are then routed along the machine to be deposited at the rear on the bench or in the axis of the way.
  • the hydraulic picker 20 takes out the old sleepers 32 one after the other from the ballast and places them on a chain conveyor 21 which brings them on a conveyor storage 21 '.
  • the lifting system 22 then lifts the turned sleepers 33 next to the spent ballast transporter 18 above the level of the sleeper transporter 23
  • the sleepers are then pivoted and turned forward 90 ° always parallel to the plane of the track, and they are then placed on the sleeper conveyor 23 to be routed to the transport gantries, not shown. After which the lifting system returns by the same path to its starting position.
  • All movements of the work cycle can be controlled automatically or manually.
  • the lifting system 22 may be arranged to lift and pivot, parallel to the plane of the track, the sleepers both around the spent ballast carriers 18 and the screened ballast carriers 19.

  • the excavator 30 (fig. 7) consists of an excavation chain, and a leveling blade 25.
  • the excavator is articulated to the chassis and suspended by hydraulic cylinders which allow the working depth to be adjusted the tilt of the platform.
  • the blade 25 is provided with adjustable side flaps during work using the hydraulic cylinders. Behind the leveling blade can be placed groomers to compact the platform.
  • the excavated material is brought by the excavation chains on the conveyors 18 to be conveyed to the screener.
  • the recovered and screened ballast is then brought back by the transporters 19 to the rear of the train in the metered ballast doser which consists of a fixed silo and a metering element adjustable in height according to the layers of ballast required.
  • the ballast is brought to the doser to form the first layer of ballast and the surplus is put on an intermediate conveyor to be evacuated to the ballast distributor on the laying wagon.
  • Behind the dispenser a tamper is placed to compact the ballast before the installation of the sleepers.
  • the present invention proposes a transport link established at will but, preferably automatically at each stop of the train. For this, is placed between the carriers of the screened ballast 19 and the spent ballast 18, a funnel 31 placed as close as possible to the excavator.
  • the transport link which creates a closed circuit between the screened and spent ballast is carried out by moving one of the screened ballast transporters 19 'using a hydraulic cylinder 39 when the machine stops (fig. 7 ).
