    MACHINE FOR REPAIRING A BALLAST BED WITH TWO SCREENING MACHINES, AND METHOD FOR REPAIRING A BALLAST BED
    TECHNICAL FIELD OF THE INVENTION
    The invention relates to a machine for repairing a ballast bed moving by rolling on a railway track.
    STATE OF THE PRIOR ART
    In the document FR 2,539,156 is described a machine for repairing a ballast bed comprising a stripping machine comprising an excavation tool defining a direction of movement of the machine, a distributor to divide a flow of incoming ballast into from the stripper in two outgoing ballast streams dissociated at least one forward screening machine fed by a first of the two outgoing ballast streams; and at least one rear screening machine fed by the second of the two outgoing ballast streams. The two screening machines are positioned side by side behind the balancer in the direction of travel. The front screening machine supplies clean ballast with a front discharge chute positioned in the immediate vicinity of the stripping machine. The rear screening machine feeds a spill chute positioned at the rear of the machine into a streamlined ballast. Conveyors transport the cuttings to one or more storage cars, positioned at the front of the repair machine, and in particular in front of the scraper and the associated railway lifting tools. By dividing the flow from the stripping machine into two parallel streams, the sizing of the screening machines is limited. But the resulting machine is not more compact than if it was equipped with a single screening machine. It also requires a long path of routing cuttings to the front end of the vehicle supporting the repair machine. It also requires a large capacity conveyor to route the ballast from the stripping machine to the screening machines. In addition, there is no provision for storage of purified ballast from the screen but in excess of the need for resetting the ballast. There is also no provision for a new ballast routing, in the case where the clean ballast resulting from the screening is insufficient with respect to the needs for resetting the track, a situation which is encountered particularly in the initial and final phases of operation. of the machine.
    STATEMENT OF THE INVENTION
    The invention aims to overcome the disadvantages of the state of the art and to provide a compact and versatile machine, taking advantage of the available space and allowing a simplified flow of the ballast.
    To do this is proposed, according to a first aspect of the invention, a machine for repairing a ballast bed comprising: at least one straightener defining a working direction of the repair machine, a distributor for dividing an incoming ballast stream from the stripping machine into at least two dissociated outbound ballast streams; at least one rear screening machine positioned in the direction of movement behind the stripping machine, and fed by a first of the dissociated outgoing ballast flows; and at least one forward screening machine powered by a second of the outgoing dissociated ballast streams; and positioned in front of the straightener.
    By positioning the two screening machines on either side of the balancer in the direction of travel, it is possible to use both ends of the machine for storing, evacuating or conveying clean ballast or cuttings, by the route being repaired, or if necessary by one or more parallel tracks.
    According to a preferred embodiment, the distributor is disposed between the rear screening machine and the front screening machine, preferably directly at the outlet of the stripping machine. The distributor is thus close to the stripper, so that the distance to be traveled by the outflow coming from the stripping machine before its division is minimized. The subsequent routing of the ballast to the front and rear screening machines requires only a reduced flow rate with respect to the outgoing flow, which allows a reduction in the size of the transport paths to the screening machines. The first of the outgoing decoupled outgoing ballast flows, referred to as the outgoing outgoing ballast flow, is routed backward and towards the rear screening machine, while the second of the outgoing outgoing ballast streams, referred to as forward outgoing ballast flow, is routed forward and toward the front screening machine.
    The stripper is positioned on a car said stripping. The front screening machine can be positioned preferably on the stripping wagon, or where appropriate on a front screening wagon separate from the stripping wagon. The rear screening machine can be positioned on a rear screening wagon separate from the stripping car. This arrangement promotes the modularity of the entire machine. Preferably, the distributor is disposed on the stripping wagon, the proximity between the distributor and the stripping machine is, as we said, favorable in terms of ballast flow management.
    According to one embodiment, the machine for repairing a ballast bed further comprises at least one refilling plow before positioned behind the stripping machine, and a front relining conveyor for conveying clean ballast of the machine. from front screening to the front relubrication plow. The front screening machine is thus used in a privileged way for relining the track. Preferably, the front relubrication plow is positioned in close proximity to the stripper behind it. In fact, the stripping machine is always associated with a lane lifting block which precedes it and allows it to work in the ballast bed under the raised track. The front relining plow is intended to work, as the stripper, in this portion of the site where the way is raised. Preferably, the front plow plow is positioned on the stripping car. If necessary, the positioning of the relining plow can be adjustable, so as to move towards or away from the straightener.
    According to one embodiment, the machine for repairing a ballast bed comprises a rear relining conveyor for conveying clean ballast for use from rear to front to the front relubrication plow. This rear relining conveyor is particularly useful when the front screening machine is stopped, or to complete the production of the front screening machine. According to one embodiment, this rear relining conveyor can be powered by the rear screening machine. Alternatively or cumulatively, it can be powered by a ballast tank fit for use.
    According to one embodiment, the machine for repairing a ballast bed further comprises a bidirectional purified ballast conveyor for conveying clean ballast from the rear screening machine alternately forwards or backwards. This bidirectional conveyor thus allows at least two different uses of the purified ballast produced by the rear screening machine. According to one embodiment, a front end of the purified ballast conveyor feeds the rear relining conveyor.
    According to one embodiment, the machine for repairing a ballast bed further comprises a ballast tank suitable for use, and one or more conveyors for conveying clean ballast for the use of the ballast tank. clean for use in the ballast bed. The ballast tank suitable for use can be used especially as a new ballast tank, useful in particular at the beginning of a sequence of work, when the straightener enters the ballast bed, or at the end of a work sequence. when the straightener comes out of the ballast bed. Preferably, the conveyor or conveyors can route the clean ballast to the use of the plow before refilling, or if necessary to a rear plow plow.
    Alternatively or cumulatively, the ballast tank can be used as a buffer storage for purified ballast in excess of relining needs. Indeed, the volume of purified ballast generated by the treatment of the total flow exiting the stripper by the two screening machines is generally greater than the need for relining, at least in the permanent operating phases out of the startup sequences and stop. It is therefore advantageously provided that one end of the bidirectional purified ballast conveyor is poured into the ballast tank suitable for use.
    The ballast tank clean for use may in particular be positioned between the stripping machine and the rear screening machine or back of the rear screening machine. By positioning the ballast tank in the immediate vicinity of the forward relining plow, ballast travel times to the front relubrication plow are minimized, thus the response times of the machine. By choosing instead to position the ballast tank behind the rear storage machine, it shortens the conveyor of the distributor to the rear screening machine. It is also possible to unhitch the car carrying the ballast tank and replace it.
    It should be noted that it may be necessary to dispense with storage of a portion of the purified ballast from the front screening machine. Indeed, by controlling the outgoing ballast flow before feeding the front screening machine, it is possible to precisely control the flow of clean ballast leaving the front screening machine, and limit this flow to what is necessary. Only if the screening capacity of the front screening machine becomes insufficient to feed the relubrication plow (eg if the ballast from the stripping machine is in poor condition and generates relatively little clean ballast In practice, this means that the repair machine does not have, or not necessarily, a ballast tank in front of the straightener. that the refurbishing machine does not have a clean ballast conveyor from the front screening machine to the ballast tank, which is a further simplification.
    In practice, and to avoid storage of purified ballast from the front screening machine, it is expected that the distributor has a variator to vary the ratio between the first and the second outgoing flow ballast dissociated. Drive control can be manual or automated, depending on parameter measured or estimated, in open loop or closed loop. The refurbishing machine may in particular comprise means for controlling the flow rate of the second of the dissociated outgoing ballast flows as a function of a target flow rate of the reloading ballast, such that the flow rate of the second of the dissociated outgoing ballast flows is less than or equal to the target rate of application of the reloading ballast.
    According to one embodiment, the machine for repairing a ballast bed further comprises at least one rear relubrication plow positioned behind the stripping machine and supplied with ballast purified at least by the rear screening machine. When the machine has both a front relining plow and a rear relining plow, the function of the rear relining plow is primarily to distribute an additional ballast on the track that is already resting on the ballast bed replenished by the plow of relining before.
    Alternatively, and especially in the event that the repair machine is devoid of rear plow plowing, it should be noted that it is possible to dispose the ballast tank in front of the stripper, preferably between the baler and the screening machine before. In this hypothesis, the relining plow, located behind and close to the stripping machine, is supplied with priority by the rear screening machine, a conveyor being provided between the ballast tank and the relining plow to provide a supplement of supply of clean ballast or new ballast when necessary.
    Preferably, the machine for repairing a ballast bed further comprises at least one front cutter conveyor for conveying cuttings at the output of the front screening machine to at least one cuttail car before positioning forward. of the stripper, and preferably in front of the front screening machine, or on an adjacent track. Similarly, the machine for repairing a ballast bed further comprises at least one rear cutter conveyor for conveying cuttings at the outlet of the rear screening machine to at least one rear cuttail car to be positioned behind the rear cutter. stripper, and preferably behind the rear screening machine, or on an adjacent track.
    According to a preferred embodiment, the stripping machine has a given nominal ballast excavation capacity, and in that the front screening machine and the rear screening machine each have a nominal capacity of screening strictly less than the capacity. nominal excavation of the stripping machine, preferably less than 80% of the excavator's nominal excavation capacity, and strictly greater than half the excavator's nominal excavation capacity, preferably greater than 60% of the capacity nominal excavation of the stripping machine. By providing a slight overall overcapacity of screening, it facilitates a judicious distribution of screening between the front screening machine and the rear screening machine. In addition, it is possible to operate in degraded mode, in the event of failure of one of the screening machines, or in economy mode, by using only one screening machine when the stripping machine is not operating at full capacity.
    According to another embodiment the stripping machine has a nominal ballast excavation capacity given, and in that the front screening machine and the rear screening machine each have a nominal capacity of screening greater than or equal to the capacity nominal excavation of the stripping machine. This embodiment allows, at the cost of greater space than the previous embodiment, to work at full speed with only one of the two screening machines, which offers great flexibility in operation. It is then possible, for example, to dispose of the cuttings alternately at both ends, which enables the refurbishing machine to operate continuously: in an operating phase, the distributor directs the spent ballast stream to one of the screening machines. and the cuttings of this screening machine are evacuated to the corresponding end of the refurbishing machine where there is a cuttail car. When the latter is full, the distributor divides the entire flow of spent ballast to the other screening machine and the cuttings produced are evacuated to the other end of the repair machine where there is another wagon cuttings, this which gives time to replace the full car at the first end with a new empty excavation car. The transition between the two phases is instantaneous, so that the replacement of the excavation car can be done without stopping the stripping machine.
    According to another aspect of the invention, it relates to a method of repairing a ballast bed comprising: stripping the ballast bed by means of at least one stripper moving relative to the bed of ballast in a direction of work displacement, a distribution of a ballast stream from the stripping machine into at least two dissociated outbound ballast streams; performing a screening of a first of the outgoing ballast streams dissociated behind the stripping in the direction of travel; and performing screening of a second of the dissociated outgoing ballast streams ahead of screening the first of the dissociated outgoing ballast streams and forward of the stripping in the direction of travel.
    Preferably, the flow rate of the second of the dissociated outgoing ballast flows is varied as a function of a target flow rate of the reloading ballast, so that the flow rate of the second of the dissociated outgoing ballast flows is less than or equal to the target rate of application of the reloading ballast.
    Screening of the second of the dissociated outgoing ballast streams results in a stream of streamlined ballast before and a stream of cuttings before. The forward purified ballast stream is preferably fully re-routed on the forward track of a forward reline plow. The flow of front cuttings is preferably evacuated from the front or on the side.
    [0024] Screening of the first of the dissociated outgoing ballast streams results in a stream of clean backward ballast and a backburst stream. According to the embodiments of the method, the backward purified ballast stream may be at least partially stored in a ballast tank and / or at least partially re-routed on the track, in front of a forward and / or backward plow plow. a rear relubrication plow. The flow of back cuttings is preferably evacuated from behind or to the side.
    BRIEF DESCRIPTION OF THE FIGURES
    Other features and advantages of the invention will become apparent from reading the description which follows, with reference to the accompanying figures, which illustrate: FIGS IA to IC, a machine for repairing a ballast bed according to a first embodiment of the invention; FIGS. 2A to 2C, a machine for repairing a ballast bed according to a second embodiment of the invention.
    For clarity, identical or similar elements are identified by identical reference signs throughout the figures.
    DETAILED DESCRIPTION OF EMBODIMENTS
    In Figures IA to IC is illustrated a machine 10 for repairing a ballast bed 12 intended to circulate on a track 14 being repaired in a direction of movement 16 from right to left in the figures. The repair machine is here composed of four wagons 18, 20, 22, 24 the first two wagons 18, 20 being illustrated in Figure IA, the last two 22, 24 in Figure IC, Figure IB showing the two intermediate wagons 20, 22.
    In the context of the present description, the term wagon is used to designate a unit resting on several running gear, generally a front bogie and a rear bogie, to travel on the track 14 being repaired. Such a unit generally comprises a rigid frame which supports the functional elements. Preferably, each car 18, 20, 22, 24 has its own bogies, distinct from the bogies of the adjacent wagons, although the use of running gear shared by two adjacent wagons is also possible.
    The first car, said energy provider car 18, comprises the hydraulic and / or pneumatic motors and pumps necessary for feeding the refurbishing machine 10. It may also include a room for the personnel, a station of order, one or more tool shops or repair shops.
    The second car, said in the following stripping car 20, supports a stripper 26, a distributor 28 and a screening machine before 30, arranged in front of the distributor 28 and in front of the straightener 26.
    The term "stripper" means in a known manner a machine provided with an excavation tool which is positioned partially under the track and allows the excavation of the ballast. The tool may be constituted by an endless chain which has a lower part located at each moment under the track, across the track, an upper part driven by a motor, and side parts which follow two ramp paths of which the one, ascending, makes it possible to route the ballast from the lower part to the upper part, where it flows directly into the distributor 28.
    The name "screening machine" covers any type of machine that allows treatment of used ballast from the stripping machine to extract or to produce a clean ballast that can be used for relining the way. This type of machine, well known to those skilled in the art, may include vibration generators and one or more staged grids to treat the ballast and separate the cuttings.
    The splitter 28 divides the incoming ballast stream from the balancer 26 into two separate flows, namely an outgoing ballast stream forward conveyed by a worn ballast conveyor before 32 to the front screening machine. 30, and a rear outgoing ballast flow routed through a rear spent ballast conveyor 34 to a rear screening machine 36 positioned on the last car 24, said rear screening car. The splitter 28 can be realized in various ways. It may be for example a tray fed from the top and having in the lower part two outputs of which at least one, and preferably both, can be opened or closed by flaps. One can also have a single flap at the bottom of the tray, the variable positioning of which divides in variable proportions the flow entering into two outgoing flows. The distributor 28 may also be constituted by a first conveyor partially placed in the flow from the stripper 28 and capturing only part of this flow, the other part being recovered by a second conveyor placed below the first. The splitter preferably allows a variation of the distribution of the incoming flow into two outgoing dissociated flows. This variation capacity can be continuous or incremental, and is preferably total, in the sense that it preferably makes it possible to direct all the incoming flow towards the used ballast conveyor before 32, or towards the spent spent ballast conveyor 34, or in varying proportions [eg 80% forward and 20% backward, or 50/50 or 20/80).
    The term "conveyor" any type of belt, chain or conveyor belt, or more generally any continuous transport device following a predefined path in one or more sections, between two points of the repair machine 10, when of his displacement. Such a conveyor may in particular comprise motorized parts and non-motorized parts, for example slides, for parts where a gravitational path is possible. In the embodiment illustrated in FIGS. 1A-1C, the used ballast conveyor before 32 comprises a single bent section, or two straight sections in the same rigid structure, since the two machines that it connects are located on the same wagon. . The rear spent ballast conveyor 34, by contrast, has several sections, at least one part wagon, which flow successively into one another. These conveyors are most often mobile and / or telescopic, to allow a great modularity of operation. When passing from one car to another, a conveyor section usually empties into another, and it may be necessary to provide that one and / or the other of the sections is pivotable about a vertical axis, for take into account the position variations of the wagons with the curve of the track.
    In known manner, the stripper 26 is associated with a lifting block of the track 38, located directly before the stripper, and which allows to lift the track where the excavation itself by the stripper 26 is product.
    The front screening machine 30 receives the forward ballast stream conveyed by the used ballast conveyor before 32 and processes the spent ballast to produce clean ballast and cuttings. A front cutter conveyor 40 conveys the cuttings at the outlet of the screening machine before 30 to at least one front cuttail wagon [not shown] positioned in front of the energy-supply wagon 18. The front cuttable conveyor 40 can also be provided pivoting about a vertical axis, to supply if necessary a wagon cuttings located on a parallel track. The stripping wagon 20 also supports a pre-relining plow 42 positioned remotely and aft of the stripper 26, and a forward relining conveyor 44 for conveying the purified ballast from the front screening machine 30 to the track 14. , before or at the plow plowing before 42 and back of the balancer 26. The plow before refilling 42 has the function of distributing ballast clean use, that is to say either the ballast cleaned, or new ballast, in the cavity made by the stripper, before resting the track on the ballast thus distributed. The front relubrication plow must therefore be in a part of the site relatively close to the track lifting block 38.
    The rear screening machine 36, disposed on the fourth car 24, said rear screening car, receives the used ballast conveyed by the rear spent ballast conveyor 34 and processes the spent ballast to produce clean ballast and cuttings. A rear cutter conveyor 46 conveys the cuttings at the outlet of the rear screening machine 36 to a rear cutter wagon (not shown) positioned behind the repair machine 10. The rear cutter conveyor 46 can also be provided pivoting around a vertical axis, to supply if necessary a wagon of cuttings located on a parallel track.
    The rear screening wagon 24 also supports a rear plowing plow 48 supplied with ballast purified by the rear screening machine 36. The rear plowing plow 48 is intended to distribute clean ballast for laterally use from and other of the track and between the sleepers, in a section of the site where the track already rests on the ballast proper for the use spread by the plow before refilling 42.
    Between the stripping car 20 and the rear screening car 24 is disposed the third car, said storage car 22, which essentially comprises a clean ballast tank for use 50.
    The clean ballast produced by the rear screening machine 36 is collected by a bidirectional rear purge ballast conveyor 52, which in one direction of operation (rearward) can feed the rear plow plow 48, and in the opposite direction (towards the front) makes it possible to feed the clean ballast tank 50. A rear reloading conveyor 54 makes it possible to convey, if necessary, the ballast present in the storage wagon 22 until to the relubrication plow before 42.
    Remarkably, there is no clean ballast tank for use in front of the straightener 26 and, at least under normal conditions of use, the screening machine before 30 does not power the own-use ballast tank 50 located behind the trimmer 26.
    Indeed, the refurbishing machine 10 is designed so that all the clean ballast produced by the screening machine before 30 is directly routed to the relubrication plow before 42, without intermediate storage. As has been stated above, the total volume of purified ballast produced by the two screening machines 30, 36 is most often greater than the ballast requirements at the level of the plowing plow before 42. But it is possible to limit the production of ballast purified by the screening machine before 30 so that it never exceeds the needs, by limiting the flow of spent ballast to the screening machine before 30. The control of the clean ballast produced by the screening machine before This is essentially done by changing the proportion of the spent ballast to the front screening machine at the level of the distributor 28. The excess spent ballast excavated by the balancer 26 and not directed to the front screening machine 30 is directed to the rear screening machine 36 which supplies the rear plowing plow 48 and / or the clean ballast tank 50. In operating phases where the production of purified ballast by the front screening machine 30 becomes insufficient (either because of a malfunction of the screening machine before 30, or because of the nature or quantity of the ballast excavated by the straightener 26], the the amount of missing ballast is conveyed from the own-use ballast tank 50 to the track 12 at the forward reload plow 42 by the rear-reloading conveyor 34.
    The control means of the distributor 28 may include means for estimating the volume, the mass and / or the reloading ballast flow required at the level of the reline plow before 42. They may also include means for measuring or estimating a degree of opening of a dispatch splitter 28 or of the quantity (mass, volume and / or flow) of spent ballast conveyed to the screening machine before 30. They can also include means for measuring the power, energy, speed or other quantity characteristic of the operation of the front screening machine 30. They may also include means for measuring or estimating the quantity (Mass, volume and / or flow rate) of purified ballast produced by the front screening machine 30, or present on the forward relining conveyor 44 connecting the front screening machine 30 to the front relining plow 42. The divider 28 can t also be controlled from manual setpoint values from a cockpit.
    It is understood that under normal conditions of use, the ballast stream excavated from the balancer 26 is intended to always be shared between the screening machine before 30 and the rear screening machine 36, so that it is not necessary for the screening machines 30, 36 to individually absorb all the flow from the stripper 26. The front screening machine 30 and the rear screening machine 26 therefore preferably each have a nominal screening capacity. strictly below the excavator's nominal excavation capacity 26, preferably less than 80% of the excavator's nominal excavation capacity 36, and strictly greater than half the excavator's nominal excavation capacity 36, preferably greater than 60% of the excavator's rated excavation capacity. In case of failure of one of the screening machines 30, 36, the repair machine 10 can still operate in degraded mode at reduced speed.
    If the size of the screening machines 30, 36 is not a limiting criterion, it can also be provided that each screening machine 30, 36 or at least one of them, preferably the screening machine before 30 has a nominal screening capacity at least equal to the excavating capacity of the scraper 26. In such a case, the repair machine 10 can operate at its rated excavation speed by returning the entire flow to only one of Screening machines 30, 36. The repair machine can thus operate at its nominal speed by returning all the cuttings to the choice forwards or backwards, which allows to adapt very freely to the constraints of the site, following it is easier to circulate the wagons of cuttings in front of or behind the refurbishing machine 10. This sizing of the screening machines 30, 36 also makes it possible not to interrupt the excavation when a wagon of cuttings to one end of the refurbishing machine is full and must be replaced by another. Indeed, it is then possible to momentarily postpone all the spent ballast flow to the other screening machine and the other end of the repair machine 10, at least for the time of the change of cut wagon.
    The embodiment of Figures 2A to 2C differs from the previous in particular by the positioning of the own ballast tank for use 50, and the storage car 22 which carries it. Indeed, the clean ballast tank 50 is positioned behind the rear screening machine 36 and, therefore, the storage car 22 is positioned at a distance from the forward reload plow 42, which shortens the conveyor worn back ballast 34 but extends the back cutter conveyor 46 between the clean-up ballast tank 50 and the front relubrication plow 42. The clean ballast conveyor 52 which directly collects the clean ballast produced by the back-sieve machine 36 is bidirectional. When it is driven in a first (forward) direction, the purified ballast conveyor 52 is discharged through its forward end into the rear refill conveyor 54 which feeds the front relubrication plow 42. When fed with In the opposite direction (towards the rear), the purified ballast conveyor 52 is discharged by its rear end at the level of the rear plowing plow 48. It is not intended to convey a surplus of purified ballast to the ballast tank clean for use 50, which therefore contains only new ballast. A new ballast conveyor 56 is placed directly at the outlet of the own-use ballast tank 50, which allows, by opening the clean ballast tank 50, to supply new ballast to the reloading plow. rear 48 and / or the plow back before 42, if necessary in addition to the clean ballast from the rear screening machine 36.
    Naturally, and as one skilled in the art will readily understand, this refurbishing machine 10 can be supplemented with additional wagons, to add if necessary functions.
    Various modifications are possible. In particular, the distribution of the various elements of the repair machine on the different wagons may vary. For example, the front screening machine may be disposed on a front screening car separated from the stripping car, at the front thereof.
    Of course, the examples shown in the figures and discussed above are given for illustrative and not limiting. It is explicitly provided that the various illustrated embodiments can be combined with one another to propose others.
    It is emphasized that all the characteristics, as they emerge for a person skilled in the art from the presentation of the application, even if concretely they have been described in relation to other characteristics individually or in any combinations, may be combined with other characteristics or groups of features disclosed herein, provided that this has not been expressly excluded or that technical circumstances render such combinations impossible or meaningless .
