As shown in figure 1 in a first embodiment of the invention, a train for loading, transporting and unloading long welded rails comprises a plurality of wagons 2 which can move on a railway track with wheels 3 and a machine rail loading and unloading, noted 5, which is movable over the entire length of the train to be able to put the rails on the platform 7 of the cars. The machine 5 moves along the train being suspended and guided under a monorail device 9 formed by aligned monorails 10 each provided on a wagon, above the platform 7, raised by gantries 12 which are mounted on the wagon at the outer edges of the platform.

The loading and unloading assembly 5 is shown on the figure 1 in its gripping position a pair of rails of which only a section marked 14 is shown.

As shown in particular figure 4 , the mobile machine 5 is suspended from the monorail device 9 by two carriages 17a, 17b each provided on each longitudinal side of a plurality of motorized wheels which are adapted to be in rolling contact on the tracks 19 of the monorails 10. A this end, as shown in figure 6 each monorail is formed by a U-shaped section whose branches extend vertically downwardly from the base 21 and each carries at its free end a horizontal tread, the inner portion of which constitutes the track 19 of the wheels of the carriages 17a, 17b. These carriages are separated from one another in the axial direction of the monorails by a predetermined distance and are arranged and configured so as to ensure easy crossing of the spacings between the two monorails 10 of two adjacent wagons.

The mobile machine comprises under the carriages a nacelle comprising a cabin 25 and a housing portion 26 of a power supply group, and two devices 27 for gripping the rails. Each device 27 essentially comprises an arm 29 which is articulated by an end 30 to the body of the moving assembly and carries at its free end the clamps 32 for gripping the rails 14.

The arms 29 are pivotally controlled by cylinders 31 interposed between the front face of the movable assembly and a location located for example in the central part of the arm. The clamps 32 are pivotally controlled by appropriate jacks 33 arranged between the corresponding arm 29 and the clamp.

The trolleys are mounted on the cab, pivoting about a vertical axis.

As shown in figure 7 , the number and arrangement of the wheels 18 of the carriages 17a, 17b is chosen so that when crossing the spacing between the ends of the two monorails 10 adjacent, the carriages are supported by their wheels on the raceways 19 of the two end portions of the monorails adjacent.

The figures 1 and 5 show further that the train according to the invention comprises a trailer 34 troughs 35 with its drawbar 37, which serves to guide and support the rails 14 during loading and unloading of the wagon. The trailer is intended to be placed on the railroad track of the train upstream of the first wagon and is stored thereon during the transport of the rails placed on the wagons, as shown in FIG. figure 6 on which we see in the foreground the chute trailer with its drawbar.

The wagons 2 are equipped with storage means in several layers of the rails on their platform 7. The reference 42 indicates a storage rack device or storage which comprises, in the example shown, three storage rack combs 43 to 45, which are superimposed in the vertical direction to form three rail storage beds in three levels. The storage racks extend, in their working position, that is to say, storage rails, perpendicular to their wagon. The lower rack 43 is permanently disposed on its wagon while the two upper combs 44 and 45 are pivotally retractable about a vertical axis located at a gantry 12 of a pair of gantries, between a rest position in which the rack extends between the two gantries, that is to say in the longitudinal direction of the wagon, the edge thereof and a working position, perpendicular to the longitudinal axis of wagon.

As we see on the figure 1 , the train of storage cars can be equipped with a safety gate 47, which makes it possible to lock the rails stored on devices of storage or storage racks when a transport movement of the train. The security gate is pivotally movable by jacks 49 between a lowered position (not shown), and a fully raised position to act as a safety stop.

There is still on the first car a lift table 48 to help the storage of rails in the second and third level of storage racks. This table also serves to relieve the efforts of grippers 32 of the rails during the operation of loading or unloading rails arranged in successive layers, for example with ten rails per layer.

Regarding the operation of the transport, loading and unloading train according to the invention which has just been described and is represented in the figures only by way of example, non-exclusive, it is already apparent from the description which has just been made . For a loading of long welded rails, the chute trailer 34 is lowered from the first car on the railway and gripping devices 27 are deployed, as shown in FIGS. figures 1 and 5 , the movable assembly 25 being in its position at the upstream end of the first car. After having grasped the rails to be stored, the moving assembly moves, using these carriages 17a, 17b, along the monorails 10 of the wagons 2 to pull the rails on the wagons to their storage position. During this movement of the rails, these are supported by storage racks 43 to 45 and the lifting table 48. As it was written above, when crossing the spacing of the ends of the two adjacent rails, the carriages are perfectly supported on the end portions of the two rails.

It will be understood from the description of the invention that it offers greater safety of use compared with the conventional loading method which uses a running track of the moving assembly, which is consists of two guide rails located at the sides of the platforms, the storage space is then reduced.

The invention composed of a system of monorails frees up all the space of the wagon platform. No motorized wheel circulating on either side of the wagon can come endanger the personnel of the surrounding yards. Thus, the new design of the invention makes it possible to offer the greatest safety in the operating mode and the organization of the work of loading and unloading the long welded rails. The monorail is itself suspended from gantries integral with the platforms of the transport wagons and the gantries to hold the suspended monorails guarantee the lateral maintenance of the long rails welded in the transport limit of the gauge of circulation of the way. Thus, the invention makes it possible to secure the mode of loading and unloading of long welded rails.

The Figures 8 to 14 show a second embodiment of the invention, the advantage of which lies in the fact that the monorail device 9 is no longer supported by gantries, but by support posts 51 located in the middle of the platforms of the wagons so that the longitudinal edges of the wagons are clear. This configuration of the wagons also allows lateral loading of the rails by appropriate gantries.

In this embodiment, the mobile machine rated 50 no longer moves under the monorails of the cars, but above them. For storage rack or rail storage devices in accordance with the figure 14 at least the two upper racks now 52, 53 are now rotatably mounted around a central column 54, between a rest position in which the racks of a length corresponding to the width of a wagon extend into the longitudinal direction of the wagon, as indicated in dashed lines for rack 52, below the monorail and in their position working perpendicular to the longitudinal direction of the wagon.

Regarding the monorail device 9 which constitutes the runway of the mobile machine 50, it is formed, as in the first embodiment, by the alignment of the individual monorails of the cars. As shown in particular figure 13 each monorail is formed by a transverse support beam 60 and two parallel mushroom rails 61 which are fixed on the horizontal upper face of the beam. This is supported by the vertical support posts 51 arranged at a predetermined distance from each other, in the longitudinal direction of the wagon, at the central longitudinal line.

Concerning the mobile machine 50, it comprises a frame at the front end of which are articulated the two rail gripping devices which are identified, as in the first embodiment, by the reference 27 and whose configuration could be the same. that in this first embodiment.

The chassis of the machine 50 carries a control cabin 63 for two operators, and in the rear part, a housing compartment of a generator set 64. A ladder 65 for access to the cabin is provided on each side of the engine. the cabin. This comprises two driving stations for individually controlling each gripping device 27.

The translation, that is to say the movement of the machine along the monorail device over the entire length of the train on the raceway, is provided by an operator. The operator's seats are elevated to ensure perfect visibility when working and moving the machine. The controls of the various functions of the machine are included in the armrests of the seat in the form of electrically operated manipulators. Large glazed surfaces provide a perfect view of the gripping operations. of the rear vision cameras (not shown) allow the vehicle to circulate in both directions safely.

The translation system enclosed in a housing 67 is equipped with two axles 69 each carrying two rollers 70, each of which rolls on a rail 61 ( Figures 12.13 ).

The drive of each axle comprises two unrepresented hydraulic motors, each intended to drive in rotation, via a chain 73, a pinion 74 disposed at one end of the axle. The rear axle is articulated at its center to ensure the crossing of the left in the raceway.

The translation system comprises a device for securing the guiding of the mobile machine which comprises four rollers 75 with a vertical axis each provided with a flange 76, as shown in particular in FIG. figure 13 , allowing a lateral guidance of the machine relative to the side of the rail 61. The flange 76 of each roller 75 is situated under one of the two sides of the head 77 of the rail, preferably on the outside, in accordance with the figure 13 , which avoids an accidental derailment of the vehicle even when handling remote loads. As shown in the figures, each axle 69 is associated two rollers 75, located near the rollers 70 carried by the axle.

By way of example, to give an idea of the dimensions of the rails 61 and the rollers 75, in order to guide the machine 50 on the rails 61, in the context of the invention, rails 61 having a height a of 172mm, a width b of 74mm, a width c of the intermediate part between the foot and the flange of 16,5mm. The rollers 75 with vertical axis have a body portion with a diameter d of 184 mm while the outer diameter e of a flange 76 is 224 mm. The width f of the feet is 150mm. Concerning the gap g between the two parallel rails 61, it could be 460mm. The distance h from the axes 79 of the two rollers 75, in the direction perpendicular to the longitudinal direction of a car, is 720 mm. The axes are held in the horizontal support element 81 of the frame of the mobile machine 50 moving on the rails 61, the invention provides solid anchoring elements 83 on the beam 60, which engage on the feet rails.

Of course, the dimensions that have just been given by way of example may be different, provided that the securing device ensures safe guidance of the machine on the rails 61.

The translation system is completed by four double-hung brakes (not shown) actuated by spring with a hydraulic return which ensures braking and immobilization of the machine in large ramps. During the translation of the machine, the operator holds the brakes open by pressing the pedal while its release causes the closing of the brake and thus the cutting of the translation.

Of course the design of the train according to the invention and its loading and unloading system as shown in the figures have been described by way of example and multiple modifications can be made without departing from the scope of the invention.
