Definitions

  • the present invention relates to a railway train for the renewal of railway tracks, comprising an operational assembly provided with means for removing the old rails, and means for allowing at least one of the axles to advance on the already deprived track of the rails.
  • the aim of the present invention is to improve the known railway trainsets intended for the function described, by providing for them a device for supporting and guiding the advance which allows the trainset to proceed on the railway track already deprived of the rails, by following the correct route, and which is free from the drawbacks of known devices, or which presents them in a more reduced measure.
  • the operational assembly of the railway train according to the invention (which can be preceded, as usual, by storage wagons which transport the new materials to be laid and which are intended to receive the old materials removed , and followed by other vehicles carrying operational means), advances, by one or more axles which precede the axle in question, on the track to be renewed, previously freed from the fasteners, removes the old rails and advances by the axle considered on old sleepers still laid, with the interposition of sections of rails which bear on the sleepers, or else on the rail supports when these are present on the sleepers, and are guided by them, so that the whole results correctly supported and faithfully follows the pre-existing layout.
  • the advancement of each section of rail is carried out when no load is applied to the corresponding axle, respectively on the auxiliary bogie, and consequently there is no danger of difficulties in advancing the sections of rail, nor of displacement of the sleepers.
  • said means allowing at least one of the axles to advance on the already deprived track of the rails also comprise detector means arranged to detect the approach of said auxiliary bogie and said axle at the anterior ends and, respectively, posterior to the travel used on said sections of rail, and means for coordinating the operation of parts of the train, controlled by said detector means and arranged to cause, alternately for said axle and for said auxiliary bogie, the transfer of the load on the other of them and the advancement of its own sections of rail, as well as to cause the blocking of the transverse displacement of the auxiliary bogie only during the periods when it is subjected to the load.
  • the operation of the means for supporting and guiding the advancement of the railway train results in fully automatic operation and does not involve the action or the control of the operators.
  • Figure 1 is a side view on a small scale of the operating assembly according to the invention, formed by two vehicles;
  • Figure 2 shows on a larger scale the means to allow the second axle of the first vehicle to advance on the sleepers deprived of rails.
  • a railway train for the renewal of railways generally comprises an operating assembly according to Figure 1 (predisposed to advance from right to left according to the drawing), subsequent operating means known per se, mounted on wagons not shown, which follow the operational assembly, and a certain number of storage wagons intended to carry the new materials which must be laid and to receive the old materials which have been removed, disposed (in the direction of advancement of the train) in front of the operational assembly shown in Figure 1.
  • the operating assembly according to FIG. 1 comprises two vehicles defined by their chassis 1 and 2, which are reciprocally articulated spherically at 3.
  • the vehicle chassis has a first axle 4 and a second axle 5 (which could be replaced by corresponding bogies), while the chassis of the vehicle 2 rests anteriorly, through the articulation 3, on the chassis 1, and later on its own axle 6 (which could also be replaced by a bogie).
  • the chassis 1 of the first vehicle carries, in its upper part, a transporter 7 connected to a depot 8 for the old removed sleepers, a depot 9 for the new sleepers to be laid, and a service track 10 for a portal transporter (known per se and not shown intended for the handling of materials between depots 8 and 9 and the storage wagons arranged in front of the operating unit 1 - 2.
  • the chassis 1 carries, in its lower part, an engine group II , generally a diesel engine actuating a hydrodynamic power station and an electric generator for the supply of the different operative members of the assembly, a chassis 12 provided with roller clamps 13 arranged (in a manner known per se) to lift and move the old rails which have to be removed, sleepers located below these rails, and an auxiliary bogie 14 (which can be lifted by means of a hydraulic cylinder 15) being part of the means intended to allow the uxverse axle 5 to advance on the old sleepers already deprived of the rails, these means being described in more detail below with reference to FIG. 2.
  • an engine group II generally a diesel engine actuating a hydrodynamic power station and an electric generator for the supply of the different operative members of the assembly
  • a chassis 12 provided with roller clamps 13 arranged (in a manner known per se) to lift and move the old rails which have to be removed, sleepers located below these rails
  • an auxiliary bogie 14 which can be lifted by means of a hydraulic
  • the chassis 2 of the second vehicle carries in its upper part a transporter 16, connected to the transporter 7 of the first vehicle, for the old trayerses removed, a transporter 17, connected to the depot 9 of the first vehicle, for the new sleepers to be installed, a parapetestrade 18 for checking the installation and for possible interventions on the respective mechanisms, an operating cabin 19 and a depot 20 for special sleepers to be placed in particular places, such as at level crossings.
  • the chassis 2 carries, in its lower part, a device 21 for removing the old sleepers which feeds the conveyor 16, a ploughshare 22 for leveling or removing the ballast, a group 23 of, laying new sleepers, a distributor 24 for special sleepers coming from depot 20, and a tracked support 25.
  • This latter assembly which is raised for approaching on the track when axle 6 is active, is lowered (to the position shown) for the work and allows the second vehicle 2 to proceed by relying on the new sleepers laid, still devoid of the rails (or, according to a possible alternative, laterally to said sleepers).
  • the operating assembly described acts by proceeding in continuous movement to the left according to FIG. 1, by rolling by means of the axle 4 on the old unbolted rails, by lifting and removing the old rails by means 12 - 13 while the old sleepers remain placed on the ballast, rolling on these old sleepers (as described below) by means of the axle 5 and the auxiliary bogie 14, removing by means of the removal device 21 the old sleepers that the conveyors 16 and 7 send to depot 8, leveling cu by moving the ballast by means of the ploughshare 22 and associated operating means, and by placing, by means 23 or 24, new sleepers on which the assembly advances by means of the tracked support 25. Subsequent operations (laying new rails, compacting ballast, etc.) are carried out by successive operating means (not shown).
  • the device allowing the second axle 5 of the vehicle 1 to advance on the old sleepers, which in the location of said axle are already deprived of the old rails removed by the means 12 - 13, comprises an auxiliary bogie lifting and lowering by means of a hydraulic cylinder 15.
  • the bogie 14 In the raised position, the bogie 14 does not touch the rails and does not interfere with the running of the railway train, while in the lowered position it can unload from the axle 5 the weight of the chassis 1, absorbed by the bogie 14 via the cylinder 15 subjected to pressure, or else simply bear without load on the rails, when the cylinder 15 is not under pressure.
  • the raising and lowering of the bogie 14 is guided by an appropriate kinematism, for example a parallelogram 35; in addition, the bogie 14 is able to perform a transverse movement which, moreover, can be blocked by a hydraulic cylinder 36.
  • a hydraulic cylinder 36 During the working periods, on the old sleepers, below the bogie 14, are placed short sections of rail 37 which cooperate with the bogie 14 by means of a position detector 38 and which. by means of a system of levers 40, can be moved longitudinally by a hydraulic cylinder 41.
  • sections of rail 42, provided with position detectors 43 and 44 are placed on the old sleepers below the axle 5 and, by means of a system of levers 45, can be moved longitudinally by a hydraulic cylinder 46.
  • This device operates in the following manner.
  • the rail sections 37 and 42 are arranged, respectively, below the axle 5 and below the bogie 14 and bear on the rail-carrying plates of the sleepers located below, which guide them along the route of the track.
  • the support of the rail sections 37 and 42 takes place directly on the upper part of the sleepers.
  • the axle 5 (on which in this phase the weight of the chassis 1 is applied) advances on the rail sections 42, which remain stationary relative to the crosspieces situated below.
  • the cylinder 15 is inactive and therefore the bogie 14 has no load, during this advancement phase, in which the load is applied to the axle 5, the cylinder 41 is active and it advances the sections of rail 37 with respect to the cross members located below and with respect to the bogie 14, which does not present any difficulties since the bogie 14 is not loaded.
  • This advancement of the rail sections 37 relative to the bogie 14 continues until the activity of the cylinder 41 is interrupted by the position detector 44. This also activates the cylinder 15, which then transmits the weight of the chassis 1 to the bogie 14, and consequently unloads the axle 5, and also activates the cylinder 46.
  • the bogie 14 (on which the weight of the chassis 1 now acts) advances on the sections of rail 37, which remain stationary relative to the sleepers located below.
  • the cylinder 46 which has been activated advances the rail sections 42 with respect to the crosspieces situated below and with respect to the axle 5, this which presents no difficulties because the axle 5 is not loaded.
  • This advancement of the rail sections 42 relative to the axle 5, and the advancement phase of the vehicle resting on the bogie 14, continue until the position detectors 43 and 38 interrupt the activity of the cylinder. 46 deactivate the cylinder 15 and activate the cylinder 41; therefore the weight of the chassis 1 begins to load the axle 5.
  • the cylinder 36 is connected so as to allow free the transverse movement of the bogie 14 while the weight of the vehicle acts on the axle 5, and to block this lateral movement when the weight of the vehicles is transferred to the bogie 14.
  • the bogie 14 has the possibility of adapting its own transverse position, as a function of the local curvature of the track layout, during the whole period in which the transverse position of the vehicle is defined by the axle 5, and then maintains unchanged this transverse position during the period in which the bogie 14 supports the load.
  • the advance travel of the rail sections 42 is considerably greater than that of the rail sections 37, and the load is transferred to the bogie 14 only in the period strictly necessary for the movement of the rail sections 42.
  • the length of movement of the rail sections 42 can be 40 cm, and the length of movement of the rail sections 37 can be 20 cm.
  • the device according to the invention has been described in relation to the second axle 5 of a vehicle 1 with two axles 4 and 5, provided with means 12, 13 for removing the old rails arranged between the two axles, and followed by another vehicle 2 with a single axle 6.
  • a similar device can also be advantageously used to support and guide the axle 6 of the second vehicle, instead of the tracked support 25.
  • a device like that which has been described can also be applied to support and guide the first axle 4 of the vehicle 1. In this case, the operation of the machine can be increased by reducing the internal tensions induced in the rails to negligible levels during the removal operation of these rails.
  • the rail sections 37 and 42 could be removed.
  • the rail sections 42 are prepared to be left in use, by fixing them to the plates or to the crosspieces situated below by the normal fixing members, and by connecting them, by means of the usual fishplates, one side to the old track which has not yet been renewed, and the other side to the new rails which have just been installed, thereby establishing 17 continuity necessary for the passage of the railway trains on the track.
  • This operation substantially facilitates the suspension and resumption of activity on the railway renewal train on a track which must remain open to traffic.
  • the device described presents a considerably greater operating safety than that of known devices, even of those more advanced in which below the axle of the vehicle is arranged a roller or track shoe, which is intended to slide on the sleepers under the entire load to which the axle of the vehicle is subjected, and which can, therefore, encounter difficulties, resistances or impediments to advancement, or else it can displace the old sleepers, with the result of upsetting the track on which the skate must slide.
  • railway train according to the invention can have all the characteristics described or even just a part of them, depending on the particular applications for which it is intended. Different modifications can be applied to the details described, and all parts and groups can be replaced by their technical equivalents.
