Description

The present invention relates generally and essentially to

  subject of a rolling or mobile installation for producing or developing a protective layer and in particular a layer of sand between the landing or the platform of the track and the bed of ballast of a railway ballast by means of a cleaning, purifying or screening machine for a bed of rolling ballast scrap on the railway and having a clearing or clearing device for receiving or picking up the ballast scrap and a conveyor system for feeding, placing, introducing or laying cleaned, purified or screened ballast stone and sand, with

  a conveyor belt arranged after the receiving element

  mucking chain hoist or collector or the like.

  The invention also relates to the various applications and uses resulting from the implementation of such

  installation and the assemblies, equipment,

devices and equipment providing it.

  An installation of this type, known to the public

  French patent application N 02 225 573, comprises a screening or sieving system for the separation

  sand and ballast and a

  steering, guiding or driving aid for the trans-

  separate port on the conveyor belt carried so

  able to rotate transversely to the longitudinal direction

  of the machine and having a wall or median partition for maintaining the separation At the end

  dumping or unloading of the transpor-

  a deflector or deflector is provided for discharging or discharging, of variable intensity, sand and ballast on the landing or the platform of the track.

  the sand, previously placed between the rails, is

  together with the ballast, brought to the sieving or sieving system and separated from one another and thrown, dumped or dumped on the platform or

  track level via the trans-

  carrier carried in a pivoting or oscillating manner and

  deviating device or deflector Although this

  has proved to be satisfactory in practice, it may occur because of the common collection of

  ballast and sand, an excessive request for

  sive, overload or prohibitive constraint of the machine

  cleaning, purifying or screening of the bed of

  ballast mock or various facilities must

  possibly be made to be more resistant

  In the event of humidity, the sand can be disadvantageously bonded with the ballast pile, so that separation, by the screening or drying system, can occur.

  can not be executed completely.

  The task of the present invention is thus to create an installation of the kind described at the beginning by

  which, using a cleaning machine,

  screening or screening of ballast scrap, which is customary for the cleaning of ballast pebbles, a high-performance addition or introduction of a layer of

  protection is made possible with an additional expense

  only weak construction and simultaneous

  in the context of a cleaning of the

ballast.

  The invention then consists in that, in

  the installation described at the beginning, the trans-

  carrier includes, in addition to the conveyor belt provided for the introduction or introduction of the ballast pile, at least one individual or clean conveyor belt extending sensiblemnat in the longitudinal direction of the machine for the transport of sand and arranged, with its receiving part or region or loader, before the receiving or gathering element of

  clearing, and whose spill or discharge end

  loading is placed between the receiving element

  chipper and the discharge or discharge end of the stone conveyor belt

  of ballast Parla creation of conveyor belts indi-

  vidual or clean sand, irrespective of the

  for the transport of ballast scrap, an installation which is particularly susceptible to high efficiency or high production capacity

  first time available for the remediation of the

  form or landing of the track. In addition, thanks to the

  according to the invention, in particular the discharge or discharge end of the sand conveyor belt is ensured a work execution substantially

  free from disturbances or disturbances.

  the platform or landing stage, necessary for the cleaning of the ballast pile, is then used rationally simultaneously for the introduction or application of the protective layer. without additional expense In addition, a constant separation, between the ballast pebble

  and the material of the protective layer, can be

  so that, even in the case of high air humidity, a homogeneous continuous layer of ballast and protection stone is achievable for

  long-term infrastructure of the railway.

  The installation according to the invention is in addition very

  simple in its structure and yet very productive.

  Another advantageous embodiment of the invention is that the tape arrangement

  conveyor comprises respectively a conveyor belt

  sand trap disposed laterally from each cleaning unit, both of which

  receiving or loading area beyond the former

  the front end of the cleaning machine and can be fed by railway transport vehicles which together with the cleaning machine form a linked assembly or convoy of vehicles which can be moved in common in a rolling configuration.

  installation with an extension of the transpor-

  sanders to transport vehicles on the track preceding or arranged before the cleaning machine, the cleaning machine, which is in itself already heavy, is free from

  any additional request or charge by

  In addition, no construction modifications of any kind are necessary on the cleaning machine itself, thanks to the lateral arrangement of the sand conveyor belts, so that also

  machines already in operation are used for

  at any time for such an advantageous installation

according to the invention.

  According to a further development of the invention

  the two ends of discharge or discharge of the sand conveyor belts extending laterally adjacent to the cleaning machine, are arranged being slightly closer to each other and the two portions or receiving zones or on the other hand, in which case, preferably, two other intermediate sand conveyor belts, extending laterally under the adjacent transport vehicle: ent, are associated, at their two ends, with each other. of spilling or unloading, to sand conveyor belts With these special configurations and arrangements, extensive use of conventional conveyor belts is possible, in which case

  thanks to the oblique and specularly symmetrical

  of relatively long and two-part sand conveyor belts, the transport of sand can be carried out unhindered and without any reduction in yield or productive capacity, even in tight curves of

track.

  Another advantageous embodiment of the invention consists in that the sand conveyor belts are made in such a way as to be able to bear on the railroad track by means of trains or

  rail running systems Thanks to this configura-

  Advantageously, both automatic permanent centering of the sand conveyor belts over the track and also a safe supporting support are provided, in which case, in addition, no structural connection with the cleaning machine is necessary. so that a quick assembly or combination of the ballast crushing machine with the rail transport vehicle can be carried out in an installation according to the invention as well as separation or dissociation. According to another characteristic of the invention, the sand conveyor belts are rigidly connected to the transport vehicle on the railroad track and comprise, on the underside of the conveyor belts, rails

  guidance, extending longitudinally in the longitudinal direction

  for the movement of international conveyor belts

  This configuration is advantageous in particular for a fast transformation to go from provisioning trips to use or activation and vice versa, relative to shorter processing times or In addition, various types of cleaning machines, such as for example also a switch cleaning machine for the sanitation of the platform or of the track seat bearing in points, may be connected, coupled or coupled for a short period of time to

transport on the railway.

  Another embodiment of the invention consists in that the sand conveyor belt is disposed substantially at the level of the railway or at the height of the rails.

Finally, another feature of the invention is that the two sand conveyor belts comprise a common spill or spread distributor or distributor extending into the receiving or collecting area up to the loading level of the vehicle. railway conveyor and to which is associated another conveyor belt placed in front of the working direction and arranged between auxiliary rails for a gantry crane that can be moved in a rolling manner on the railway transport vehicles Thanks to such a broad widening of the sand conveyor belts we have a

  transport installation with a specific loading capacity

  particularly high transport for high-capacity or large-capacity production, large quantities of

  sand brought by the gantry crane through containers.

  By the wide conveyor belt, located between the auxiliary rails of the gantry crane, the total contents of a container can be loaded at one time and

  continuously delivered to the distributor or distributor

  dumping or spreading device with a speed of

  slower transport, according to the needs or in accordance

  to the necessities of obtaining the thickness of the protective layer. In the meantime, for the maintenance

  of a continuous advancing movement of work of the

  according to the invention, another whole container

  loaded can be transported and brought by the gantry crane. The invention will be better understood and other purposes,
