Definitions

  • the present invention relates to an improvement in a rail car of the type utilized for carrying and transporting commercial road vehicles.
  • TIRs heavy goods vehicles
  • This type of solution allows a road haulage vehicle to be loaded and offloaded simply and swiftly, and without any requirement for special infrastructures to be incorporated into the goods yard (other than a platform elevated to the level of the rotating structure so that the vehicle can roll on or off); the embodiment of the cradle structure also permits of accommodating a variety of loads according to the needs of the moment (single semitrailer without tractor, two or more tractors, a number of medium and small capacity trucks, etc.).
  • the object of the present invention is to overcome the drawbacks briefly outlined above by improving a transporter rail car for commercial road vehicles of the type in question, in such a way that the cradle can be manoeuvred more easily and swiftly, and made safer and more stable both when loading or offloading and when in transit on the track with vehicles loaded.
  • the improvement disclosed relates to a rail car used for carrying and transporting road haulage vehicles or commercial vehicles generally (denoted 5 in the drawings).
  • the car consists essentially in a number of basic assemblies (indicated in fig 1, which shows one end of the car only given that the overall structure is substantially symmetrical in relation to a vertical plane), namely:
  • the improvement disclosed relates to the rotation means 9 mentioned above: such means consist in a virtual fifth wheel denoted RV in its entirety (see figs 4, 5 and 5a, 6 and 6a), which comprises a non-loadbearing kingbolt 10 stably interposed between the fixed structure 6 and the movable rigid cradle.structure 4 and coinciding with the barycentric vertical axis X, by which the two structures 4 and 6 are interconnected and about which the cradle structure 4 is rotatable through the agency of power transmission means consisting preferably in a pair of hydraulic actuators located between the kingbolt 10 and the fixed structure 6 (the actuators in question, denoted 10c, are shown schematically in the drawings, being conventional in embodiment).
  • each of the hydraulic actuators 10c is anchored by the rear end to the outermost part of the relative beam 6a and 6b, and connected by its rod 10s to one corresponding end of a horizontal arm 10b rigidly associated with the kingbolt 10.
  • the plurality of rolling elements 11 comprises at least two sets of four freely rotatable wheels, a first set 29 spaced diametrically closer to and a second set 30 spaced diametrically farther from the vertical axis X.
  • the wheels of the first set 29 are associated by way of bolts 36 each with a relative plate 29p welded to the underside of the moving cradle 4, and arranged two on either side of the vertical axis X of rotation in such a way as to roll in a corresponding pair of arcuate channels 31 afforded by the two beams 6a and 6b.
  • the wheels of the second set 30 are located in a plane beneath the cradle 4 coinciding substantially with the pair of beams 6a and 6b, again associated by way of bolts 37 each with a relative plate 30p, in this instance welded to the external face of the corresponding beam; more exactly, the four wheels of the set 30 are arranged two at each end of the fixed structure 6, freely engaging a second pair of arcuate channels 32 afforded by the underside of the moving cradle 4.
  • the cradle structure 4 is equipped further with stabilizing means 21 capable of vertical movement, positioned at each end and in such a manner as to interact with an adjacent hardstand C whenever the cradle is rotated into the outboard or load/offload position, thereby ensuring that the cradle itself is balanced and maintained substantially parallel to the datum surface P.
  • such stabilizing means 21 consist in pairs of hydraulic actuators 33 coinciding singly with the four corners of the cradle 4, each secured by one end to the rigid cradle structure, or rather to the respective arm 4a, by screw means 34.
  • the remaining end of the single actuator 33 carries a freely revolving wheel 35 angled so as to roll on a line tangential to the vertical axis X of rotation and capable of movement thus (see arrow F, fig 3) between two limit positions: a non-operative raised position assumed in the inboard configuration, in which the wheel 35 is disposed within the vertical compass of the cradle structure 4, and an operative lowered position of contact with the hardstand C (shown by phantom lines in fig 3), assumed when the cradle 4 is rotated from the inboard configuration to the outboard or load/offload position.
  • the freely revolving wheel 35 is associated in turn with a vertically disposed lateral rod 40 extending parallel to the axis of the actuator 33, externally of the relative barrel, which is secured to the flange of a mounting bracket 35b and slidable thus in a vertical direction together with the wheel 35 in such a manner that the wheel will be held in the tangential position and prevented from swivelling about a vertical axis when rolling in contact with the hardstand C.
  • the improved car also comprises second interlocking means 12 positioned to operate between the fixed structure 6 and the movable cradle structure 4 when in the inboard configuration, at points both on the underside of the cradle 4 at each end and where the arms 4a come to rest on the flat car bodies 6c and 6d of the respective bogies 1, in such a way as to restrain the cradle 4 longitudinally and laterally in relation to the fixed structure 6.
  • these second interlocking means 12 are shown as first and second sets of four hydraulic actuators, denoted 13 and 14 respectively.
  • first set 13 each of the four individual actuators is secured by way of screw means 15 to the fixed structure 6, horizontally disposed and directed toward a corresponding bottom face of the cradle 4, and extendible (arrow F1 in fig 3) to an operative position in which a tapered bolt 16 afforded by the free end portion of the relative rod 20 is caused to locate in a matching and correspondingly placed first socket 17 afforded by the cradle 4;
  • each individual actuator is secured vertically to a respective arm 4a of the cradle 4, substantially at the farthest extremity, and extendible thus to an operative position in which the tapered bolt 16 locates in a matching second socket 18 afforded by the respective flat car body 6c or 6d.
  • the single hydraulic actuators of both sets 13 and 14 are equipped at the end remote from the tapered bolt 16 with safety spring means 19 impinging in the axial direction on the relative rod 20 in such a way as to maintain the bolt 16 in the extended operative position in the event that the hydraulic system (denoted 41) should be less than totally efficient in operation (e.g. leakage of oil from the cylinder), and capable also of holding the bolt in a non-operative retracted position.
  • such spring means 19 consist in a conventional coil spring ensheathing a pin 42 rigidly associated with the rod 20, of which the opposite ends are retained respectively by the rod itself and by an end cap 43 constituting part of an external casing 44 in which each of the single actuators is housed.
  • the elevating means 7 are mounted to the pair of beams 6a and 6b at points near to the vertical axis X, and consist in four mutually opposed pairs of cylinders 22 and 23 of which first outer ends are anchored pivotably to separate points of a load bearing platform 24 (constituting the first interlocking means 60) associated transversely with the beams 6a and 6b and with the kingbolt 10 at centre; the remaining ends of each pair of cylinders are anchored jointly to a single foot 25 destined to enter into contact with the datum surface P, which in practice will be afforded by the railway track 3.
  • each pair of cylinders 22 and 23 is accommodated in a respective recess 26 afforded by the platform 24, which comprises two pairs of horizontal. and parallel brackets 27 and 28 secured to the relative beam 6a and 6b outside the dimensional compass of the fixed structure 6, the pairs of single cylinders 22 and 23 being disposed coaxially between the horizontal brackets 27 and 28 (as shown in fig 7).
  • the platform 24 thus performs a dual role, functioning both as a component of the elevating means 7 and as first means 60 by which the cradle 4 and fixed structure 6 are interlocked.
  • the operation of the improved transporter rail car is shown schematically in figs 8 to 11.
  • the car is drawn up alongside a shed (or indeed in any given space suitable for manoeuvring the road vehicle), and the brake applied; a function is then selected at a control unit (conventional in embodiment and therefore not illustrated, but a normal centralized unit performing a programmed sequence of steps) to enable rotation of the cradle 4 in the appropriate direction, whereupon the tapered bolts 16 are drawn back from the respective sockets 17 and 18 to the retracted non-operative position in such a way that the cradle 4 is left resting freely on the flat car bodies 6c and 6d of the bogies 1 (see fig 8).
  • the elevating means 7 are activated, with the result that the entire fixed structure 6 is raised together with the cradle 4 by the pairs of cylinders 22 and 23 and supported thus with the four feet 25 planted firmly on the datum surface P.
  • the cradle structure 4 continues to be supported stably by the beams 6a and 6b thanks to the presence of the rolling elements 11a and 11b.
  • the platform 24 (which, to reiterate, coincides with the first interlocking means 60) also impinges on the beams 6a and 6b and the cradle structure 4 during the passage from the transport position to the elevated position, the resulting mechanical interference causes the beams 6a and 6b to flex, distancing the flat car bodies 6c and 6d one from another and increasing the internal dimensions of the car in the longitudinal direction.
  • the actuators 10c of the rotation means 9 are now operated to swing the cradle structure 4 on its centre axis X through an angle of approximately 30° from the longitudinal axis of the car.
  • the cradle 4 remains actively supported by all eight wheels of the two sets 29 and 30 during the first few degrees of rotation, whereupon the increasing divergence between the cradle 4 and the fixed structure 6 (see arrow F2, fig 9) results in the wheels successively losing contact, two by two, until only two are left in a supporting position diametrically opposed on either side of the kingbolt 10 (see figs 9, 10 and 11, in which the active wheels are shown as dots, and the inactive wheels as circles).
  • the actuators 33 of the stabilizing means 21 will also come into operation during the rotation, and with the relative wheels 35 grounded, the cradle 4 is maintained parallel with the hardstand C during rotation. As the cradle finally reaches the angled position, ramps are lowered to allow the vehicle to roll on or off as the case may be (a routine step for any transporter system which is therefore not illustrated).
  • the rail car is rendered notably more stable during all manoeuvring steps involving the cradle:
