Definitions

  • the invention lies in the field of railway machines and processes for the maintenance of railways, including the total or partial renewal of the ballast.
  • ballast bed of a railroad is subject to aging as the tonnage has circulated on the track and gradually loses its particle size, mechanical and geometric properties. It must be maintained and renewed periodically, in the context of a Ballast Renewal alone, associated or not with a Renewal of crossties and / or rails (RGB).
  • a specialized railway wagon known as a straightener comprising two ends, a front end and a rear end, which two ends are defined by the direction of advance of the work train, is conventionally used.
  • a conventional stripping machine is capable of excavating used ballast, screening it, reloading the reusable ballast so as to raise the track and evacuating the non-reusable ballast, called "land", to dump cars equipped with top conveyors and hitched to the front of the straightener in the direction of the progress of the yard.
  • the most recent straighteners allow in addition to unloading new ballast supplied by ballast cars also hitched to the straightener but at the rear.
  • internal flow to the machine means a flow of material which remains confined within the stripper
  • exital flow a flow of material from or discharged to storage cars.
  • a flow of material is in practice conveyed by conveyor belt from one location to another of the stripping machine or to or from a service train consisting essentially of storage wagons.
  • the stripper receives the new ballast stream from its rear end, from ballast cars equipped with unloading conveyors (VAC), and evacuates the non-reusable ballast from its front end to dumpers with upper conveyors. (WAC).
  • ballast cars equipped with unloading conveyors (VAC)
  • WAC unloading conveyors
  • Traditional ballast boats can be unloaded from ballast by hoppers at the bottom but must be loaded by shovel, and WACs can be loaded from above by conveyor belt but must be unloaded by shovel.
  • the stripper is hitched to two sets of storage cars, one at the front to receive the "land", the other at the rear storing the new ballast.
  • VADs self-unloading wagons
  • the length of a RB site employing a conventional stripping machine is therefore limited by the carrying capacity of the wagons, itself limited by the maximum length of a train.
  • the length of the RB train is also penalizing when one wants to carry out in the same shipyard simultaneously (that is to say in the same working day) the renewal of the ballast and the sleepers, the current technology of the renewal trains ballast or sleepers that can not achieve high returns due to the distance between RB and RT operations.
  • the laying machine is supplied with sleepers from the front of the train and in RB trains, the non-reusable ballast transport wagons are also located at the front of the straightener. Consequently, whatever the order in which the work is carried out, a train of wagons will always be interposed between the cross-laying machine and the straightener.
  • the sites of RB and RT are separated by a distance D, at least equal to the length of a supply train of sleepers or non-reusable ballast cars, which can be large, typically several hundred meters.
  • the more we try to increase the daily renewal performance the longer the length of the interleaved train increases and therefore the distance D increases, the longer the duration T of The offset increases, and the working time of RT and RB decreases, that is, the daily output of the RB + RT worksite decreases.
  • the operations of RB and RT are therefore never performed simultaneously (ie the same day) on a given area, but scheduled for two consecutive workdays.
  • the document EP-A-442094 describes a stripper capable of excavating and evacuating all or part of the used ballast at one end and reloading the new ballast track at the same end.
  • the document WO-2009/029969 describes a ballast stripper, means for evacuating used ballast and receiving new ballast at the same end, separating means and means for simultaneous unloading.
  • the aim of the invention is to eliminate these disadvantages.
  • a ballast stripping machine capable of excavating used ballast of a railway line and reloading said new ballast track, said stripping machine having a first and a second end, and comprising means for evacuating all or part of the used ballast and receive new ballast at the same end.
  • the essential characteristic of the stripping machine according to the invention consists in the fact that it is able to evacuate used ballast and receive new ballast at the same end, whether it is the front end or the 'rear end. Most often it will be the rear end.
  • the stripping machine may further comprise means for evacuating all or part of the used ballast at one end and receiving new ballast at another end.
  • the stripper according to the invention retains the ability to evacuate used ballast and to receive new ballast at different ends, for example to receive new ballast from behind and to evacuate "lands" from the front.
  • the stripping machine according to the invention also has the capacity to treat the used ballast and in particular to screen it to separate it into non-reusable ballast, to be discharged, and treated reusable ballast, which can be unloaded again on track.
  • the stripper comprises means for unloading the new ballast first and the ballast retreated over the new ballast layer.
  • the stripping machine comprises, for example, at least two ballast discharge hoppers, one acting first for the discharge of new ballast at the bottom of the trench, that is to say at the level of the zones of the trench. the most sought after (under the sleepers), the other, second in charge, for the discharge of ballast treated at the level of the areas where the ballast undergoes the least constraints, such as the side benches or the boxes between sleepers. This optimizes the distribution of the new ballast.
  • the second hopper can also discharge a mixture of treated ballast and new ballast.
  • the invention also relates to a ballast renewal train comprising a stripping machine according to the invention.
  • This train of work can obviously include other elements such as one or more motor, transport and storage cars and other types of wagons, such as energy supply wagon.
  • the straightener in this ballast renewal train, can be coupled by only one of its ends, including the rear end, to a train of aggregates transport wagons.
  • the straightener has two wagons, including an excavator wagon and a ballast wagon, at the end of the stripping machine is meant the end of one wagon located opposite the other wagon.
  • the stripper is not hitched to any other transport car aggregates at its other end, which allows for example to bring another site, for example the replacement of sleepers, the ballast renewal site.
  • the train of aggregates transport cars may comprise first means for receiving aggregates from the stripping machine, for example the "lands", and convey them to fill said wagons.
  • one and / or the other of these means may / may be common (s) to the entire train, or part of the train, or be individual wagon by car.
  • non-reusable ballast will be evacuated and dumped into empty cars to avoid the mixing of used ballast and new ballast, these empty cars may have previously contained new ballast already discharged on the track. These wagons are therefore common to the transport of new ballast and non-reusable ballast.
  • the first and second conveying means are also used as a base: the second conveying means makes it possible to load the wagons of the train in new ballast from a single loading point, and the first conveying means makes it possible to unload the ballast not reusable. Both operations can even be conducted simultaneously, like the RB method, which provides a time saving base.
  • the renewal of the ballast is carried out at a substantially constant mass: the quantity of new ballast added in track is substantially equal to the quantity of used ballast removed ("the land").
  • the length of such a train RB is substantially divided by two compared to a train of RB comprising a single-straightener straightener, which represents a considerable advantage; it can also be said that the length of track that can be treated, with equal train length, is substantially doubled.
  • the system is very flexible: wagons can be hitched to the front or rear of the straightener. They can even be hitched on both sides of the straightener.
  • the invention also relates to a train work train comprising a ballast renewal train according to the invention and a train renewal of associated ties within the same renewal site.
  • ballast renewal train and the train for renewing ties can be coupled to one another.
  • the RT and RB trains are routed together or separately on the site, but they follow each other as closely as possible during the work phase, ideally both machines (the straightener and the tie laying machine). ) be coupled to each other.
  • the invention also relates to a method of renewing the ballast of a portion of a railway track, using the same machine for excavating the ballast and discharging ballast on the portion of railroad track.
  • the machine common to the two excavation operations of the used ballast and the new ballast, possibly mixed with treated ballast, is a suitable stripping machine.
  • this method makes it possible to have only a single train of storage cars in a train of RB, and therefore to substantially halve the train length of RB, for the same length of track. treated.
  • Used ballast is not usually fully won; it undergoes reprocessing steps (washing, screening, crushing of larger blocks %) in order to recompose its particle size and separate it into unusable ballast and reusable ballast.
  • the new ballast is unloaded in track before the treated ballast.
  • the new ballast is discharged in "trench bottom", that is to say under the sleepers, in the zone which undergoes the strongest stresses.
  • the treated ballast is then discharged at the surface, in a zone that undergoes less stress, such as the side benches. It is also possible to unload a mixture of new ballast and surface-treated ballast. This optimizes the use of new ballast.
  • the step of renewing the sleepers is performed before the steps of renewing the ballast.
  • the method optimizes the arrangement of the new ballast and ballast treated and reused during the reworking; a construction site following the RB construction site would destroy this arrangement.
  • the old sleepers can be fragile and break under the effect of mechanical stresses of a RB site, which would slow down considerably work.
  • the process uses a single train of storage and transport cars for the delivery of the new ballast and the winner of the non-reusable ballast. Conversely, this single train, on returning from a work period, can be emptied of the non-reusable ballast by the first transfer means and filled again with new ballast thanks to the second transfer means, these operations being able to be carried out simultaneously, providing This saves a lot of time.
  • Such a train does not include a new ballast car, the track is made with a very low level and therefore with a low LTV rate.
  • New ballast must be added in one or more passes by a ballast train, which extends the period during which this LTV applies.
  • FIG. figure 8 it is seen that there remains a "sole" former ballast 51, above which was discharged a layer of treated ballast 52, which is under the cross 55, so in the area of higher stress. A new layer of ballast 54 has been discharged over this layer of used ballast 52, so that this new ballast is located between the cross members 55 and bench, which is not an optimal use of this ballast new.

  • the train of RT comprises a train 201 of railcar transport and storage of sleepers hitched to the front of a machine 202 for crossing renewal.
  • This train operates according to the principle of "constant mass", that is to say that the train of cars 201 stores both new sleepers and used sleepers; this train does not run with empty cars.
