Definitions

  • This invention relates to a self-propelled and multi-purpose railway vehicle, that is to say, equipped with autonomous traction and configured or configurable for achieving at least two different purposes. More specifically, the railway vehicle according to the invention relates to the sector of construction site vehicles or so-called "operating vehicles", designed for the construction, overhaul and maintenance of the railway lines.
  • the aim of the invention is therefore to provide a railway vehicle which overcomes the above-mentioned drawbacks.
  • the aim of the invention is to provide a railway vehicle which is extremely versatile in its use, therefore making it available for different uses, thus reducing the need for movements of several vehicles to places where only one and a single specific operation is requested.
  • Another aim of the invention is to provide a railway vehicle for which the maintenance is simple and inexpensive.
  • a further aim of the invention is to provide a railway vehicle which complies with current standards in terms of environmental compliance and energy efficiency.
  • the vehicles for the construction and maintenance of railways are often used on lines in tunnels; the aim of the invention is to provide a vehicle which can work, at the site, with the internal combustion engine switched off in order to drastically improve the conditions of the work sites.
  • the technical purpose and preset aims are substantially achieved by a self-propelled multi-purpose railway vehicle according to one or more of the accompanying claims from 1 to 10.
  • FIG. 1 is a perspective view of a railway vehicle according to the invention.
  • FIG. 1 is a side view of the railway vehicle of Figure 1 ;
  • FIG. 3 is an exploded view of the railway vehicle of Figure 1 ;
  • FIG. 4 is an enlarged detail of the railway vehicle of Figure 1 ;
  • FIG. 5 is a cross section, according to a vertical plane, of a detail of the railway vehicle according to the invention.
  • FIG. 6 is a perspective view of a first separable component of the railway vehicle according to the invention.
  • FIG. 7 is a perspective view of a second separable component of the railway vehicle according to the invention.
  • the numeral 1 denotes in its entirety a railway vehicle according to the invention.
  • the vehicle 1 comprises a main frame 2 provided with two railway axles 3 for travelling on a railway track.
  • the number of axles is not, however, limited, as it may be even more than two and, if necessary, defined by one or more dollies where necessary, although in light of an optimisation of weights and dimensions the two-axis solution is preferable.
  • the vehicle 1 comprises a driver's cab 4 preferably fixed and which can be made, for example, according to known methods.
  • the remaining part of the main frame 2 (or part of it) defines at the top a work or loading platform 5.
  • the work platform 5 is configured for installing a plurality of operating units "W1-W3" to perform respective operations linked to the construction, overhaul and maintenance of the railway lines.
  • the operating units "W1-W3" are mounted or can be mounted on the work platform 5 inde pendently of each other and according to different configurations and/or combinations depending on the needs present each time.
  • the work platform 5 has a plurality of receiving areas 6 positioned one after another along a longitudinal axis of the vehicle 1 and preferably adjacent to each other. According to the embodiment illustrated there are four receiving areas, however the number may be different, in particular greater for heavier and structured vehicles or smaller for more agile and lighter vehicles.
  • These receiving areas 6 are configured for rapid assembly and removal of the operating units "W1-W3".
  • each receiving area “R” comprises a pair of parallel guides 7, positioned perpendicularly to the longitudinal axis of the vehicle 1 (therefore to the direction of travel) and designed to allow an application, by lateral sliding, of an operating unit "W1-W3" to the receiving area "R".
  • the parallel guides 6 may extend for the entire width of the work platform 5.
  • each guide 6 has the shape of a "C” with a front recess, facing towards the guide 6 opposite the same pair of guides, in such a way that between the two mutually facing recesses the operating unit "W” is guided or, preferably, a slidable plate 7 of the operating unit "W1-W3".
  • the lateral sliding of the operating unit "W1-W3" is achieved by means of a motor-driven system which, according to the embodiment of Figure 5, comprises a rack 8 positioned on at least one of the guides 6 and a motor-driven pinion 9 positioned on the slidable plate 7 of the operating unit "W1-W3" and engageable with the rack 8 for making a controlled sliding of the operating unit "W1-W3" along the guides 6 during assembly and removal of the operating unit "W1-W3" relative to the work platform 5.
  • a motor-driven system which, according to the embodiment of Figure 5, comprises a rack 8 positioned on at least one of the guides 6 and a motor-driven pinion 9 positioned on the slidable plate 7 of the operating unit "W1-W3" and engageable with the rack 8 for making a controlled sliding of the operating unit "W1-W3" along the guides 6 during assembly and removal of the operating unit "W1-W3" relative to the work platform 5.
  • the pinion 9 is connected to a motor or gear motor 10 with a vertical axis of rotation, mounted on the slidable plate 7.
  • the operating units "W1-W3" comprise two or more between: a crane “Wl”, an aerial work platform (lift) "W2", a reel unwinding device (not illustrated), a concrete mixer (not illustrated).
  • the operating units "W1-W3" may also comprise an auxiliary driver's cab (W3), which can be used in a transfer configuration but advantageously removable if the vehicle 1 is connected to further carriages and, therefore, the auxiliary cabin is un necessary or an obstruction.
  • W3 auxiliary driver's cab
  • the vehicle 1 made in this way therefore achieves a possibility of modular com position of the operating units "W1-W3" which therefore constitute to all intents and purposes the modular components of the vehicle 1.
  • the work platform has at least two, preferably four receiving areas "R", of which at least two of identical structure configured to receive at least two operating units "W1-W3" according to different configurations and/or combinations in such a way that the operating units "W1-W3" can be exchanged with each other.
  • the unit with crane “Wl” and the aerial work platform (lift) "W2" are interchangeable with each other but the second requires the occupation of an adjacent receiving area "R" being larger in size.
  • At least two receiving areas "R" have parallel guides 6 positioned at a re spective spacing different to each other to adapt to operating units "W1-W3" of different types.
  • the unit with a crane may require a spacing less than the reel unwinding unit.
  • the receiving areas "R" comprise one or more receiving areas provided with parallel guides 6 positioned at a first spacing value (for example, a lower spacing, for operating units with cranes) and one or more second receiving areas provided with parallel guides 6 positioned at a second spacing value (for example, a greater spacing for the aerial work platform) and, if necessary, a third receiving area with intermediate spacing positioned at the end for receiving the auxiliary driver's cab.
  • a first spacing value for example, a lower spacing, for operating units with cranes
  • second spacing value for example, a greater spacing for the aerial work platform
  • adjacent receiving areas "R” may have re spective guides 6 placed side by side in such a way that the above-mentioned recesses of the guides are positioned in opposite directions.
  • the vehicle 1 comprises a plurality of functional units "F1-F4" mounted or which can be mounted below the main frame 2 and designed to supply the power necessary for moving the railway vehicle 1 and for powering the operating units "W1-W3".
  • the functional units “F1-F4" comprise at least one hydraulic unit “FI”, a pneumatic unit “F2", a battery accumulator unit “F3” and a generator unit “F4".
  • the generating unit “F4" comprises an internal combustion engine connected to an al ternator for recharging batteries of the battery accumulator unit "F3".
  • One or more of the functional units “F1-F4", preferably each of them, is independently mountable and removable relative to the main frame 2 and, for that purpose, may be housed in a re spective containment frame 11 individually applicable below the main frame 2, and removable or extractable from it, to perform maintenance operations on the functional unit "F1-F4".
  • one or more of the functional units "F1-F4" is slidable in a lateral direction, like a drawer, from and inside a respective fixed box- shaped counterframe 20 for being extracted and re-inserted quickly and easily in the case of maintenance.
  • each functional unit “F1-F4" is entirely housed in a box-shaped con tainment frame 11 ( Figures 3 and 6) and is equipped with electrical, pneumatic and/or hydraulic connections for connection to the main frame 2 and/or to the operating units “W1-W3”.
  • At least two functional units “F2, F3” (pneumatic and battery accumulators), and preferably also a third (hydraulic, “FI”) are of the sliding type described above whilst one of them, in particular the generating unit “F4”, can be inserted from above in a corresponding fixed coun terframe 30 applied to the main frame 2 below it and configured in the form of a “cradle”.
  • the main frame 2 (therefore, the work platform 5) has at least one suitable opening to allow the passage at least of said functional unit "F4".
  • the laterally slidable functional units "F1-F4" can also be removed and reinserted from above (as well as being laterally extractable by sliding) and, therefore, for this purpose, the main frame 2 (therefore, the work platform 5) has suitable openings to allow the passage of said functional units "F1-F4" ( Figure 3), moved for example with the same crane forming part of an operating unit and mounted on the work platform 5.
  • Each opening of the main frame 2 therefore cor responds to a respective lower fixed frame 20, which also performs the function of supporting the respective laterally extractable functional unit (the fixed frame 20 being in this case configured both in the form of a cradle and a drawer),
  • Figure 6 shows in detail the generating unit "F4" where the internal combustion engine 15, the alternator 16, the tank 17, an electrical panel 18 and a radiator 19 can be seen, as well as an anti-particulate filter 20. All these components are housed inside the box- shaped frame 11, which is in turn contained in the respective counterframe 30 ( Figure 3).
  • the main frame 2 is equipped, at the ends, with stabilising and lifting actuators 14 for stabilising the vehicle during use of the crane or other accessories which generate a tipping moment or for lifting the vehicle 1 relative to the ground in such a way as to remove axles 12 of the vehicle 1 or carry out other operations below the vehicle 1.
  • Figure 7 shows an axle 12 of the vehicle 1 coupled to a respective mechanical transmission 13 of the suspended type and to the electric traction motor M, which is removable in a simple manner after the lifting of the vehicle 1 by the actuators 14.
  • the present invention achieves the preset aims, overcoming the disadvantages of the prior art.
  • the railway vehicle according to the invention is provided with electric traction and batteries for a completely electric operation, wherein the energy is guaranteed by an internal combustion engine connected to an alternator.
  • the vehicle 1 can therefore adopt a running configuration (transfer) using the energy generated by the internal combustion engine connected to the alternator, which in turn charges the batteries on board.
  • the stored energy is then used during work, in the absence of high voltage electricity, allowing the use of the operational units for several hours in fully electric mode.
  • the vehicle 1 is also equipped with a braking system connectable to carriages or other vehicles equipped with a continuous brake, allowing the vehicle 1 to be towed and in turn to tow all the vehicles of the type in use by railway personnel for the maintenance of the electrical traction systems and, in general, of all the vehicles equipped with an continuous and automatic brake system.
  • the vehicle comprises a “tare” configuration, including accessories or ballast, of 25 tonnes and a “loading” configuration of 40 tonnes for an exceptional load situation (e.g. loaded concrete mixer).
  • a “tare” configuration including accessories or ballast, of 25 tonnes and a “loading” configuration of 40 tonnes for an exceptional load situation (e.g. loaded concrete mixer).
  • the vehicle 1 is configured to be transported with a flatbed trailer with a maximum height of 700 mm from the road surface in such a way as fall within the standard road profile in height and width.
  • the maximum height of the vehicle 1 considering the wheels without wear and the suspensions compressed with the tare load, is 3.30 m from the upper surface of the track, a total height of 4.00 metres is thus reached during transport and falls within the limits required by the highway code, allowing the use of a non-exceptional transport.
  • the maximum width of the vehicle 1 does not exceed 2.54 m and in this case, too, remains within the gauge limits for non-exceptional road transport.
  • the vehicle is also easy to maintain because the elements which make up the functional macro-areas of the vehicle are positioned in box-shaped frames extractable from the frame of the vehicle.
  • the guides can be moved in such a way as to achieve different configurations suitable for modifying the layout of the possible combinations of the operating units on the work platform of the vehicle.
