Definitions
- the invention relates to an anti-pitching device for intermodal semitrailers (destined both for use on the road and for loading on railway cars), during transport on railway cars.
- the semitrailer comprises a vertical pivot projecting from a frontal part of the trailer frame, which pivot is associable with a fifth wheel of a hauling vehicle; the above-mentioned association provides a vehicle-trailer articulation necessary for transporting the semitrailer by road.
- a railway car exhibits means for fixing containers to the car, comprising spikes for blocks affording engagement holes for the spikes.
- railway cars are usually equipped for receiving various types of load, among which are semitrailers also equipped for road use and usual unwheeled containers.
- a special housing is provided for the semitrailer articulation pivot, while the back end of the semitrailer, though its wheels are housed in a special loading pit fashioned in the car floor, is free to oscillate and tilt, obeying the properties of the semitrailer suspension, when the car negotiates a curve in the railway track.
- Containers can be solidly constrained to the railway car by means of a system of spikes engaging in shaped holes in fixing blocks exhibited by the containers themselves.
- Anchoring the semitrailers in the loading pit has however proved to be effective, except where the width of said semitrailers is between 2.5 metres and 2.6 metres on lines not equipped to tolerate such measurements.
- the above drawback is due to the fact that the semitrailers, particularly if they are refrigeration-plant-equipped, or in any case wheeled trailers, tend to tilt during transport around curves, and their main sections are therefore liable to exceed the legally-set width limits for transport on certain lines.
- a further drawback is represented by the fact that with respect to the railway tracks the loading pit is higher than the fixing spikes for the containers: this means that containers loaded on to the cars (due to legal container height limits) have to be vertically shorter than would otherwise be possible, leading to a loss of transportable volume.
- the document FR-A-2534870 discloses an anti-pitching device for intermodal semitrailers during transport on a railway car, according to the preamble of claim 1.
- the railway car is provided with means for fixing a container, said means for fixing normally are constituted by spikes.
- the anti-pitching device comprises blocks affording engagement holes for the spikes, and further comprises four rigid supports bearing the blocks, which supports are rigidly constrained to the frame, and are distributed on the two opposite sides thereof. Two of said supports are located on a front part of the frame.
- the invention solves the problem by providing an anti-pitching device for intermodal semitrailers comprising rigid supports bearing fixing blocks of the semitrailer to the spikes of the railway car, arranged on two opposite sides of the car and conformed in such a way as to realize rigid connections between the semitrailer and the car which at least during the semitrailer's use as a road trailer, are positioned above the face of the frame associable to the fifth wheel of the vehicle hauling said semitrailer.
- the device of the invention affords the further advantage of permitting transport of larger-volume semitrailers, with consequent cost reductions.
- figures 1A and 1B show that the invention largely consists in an anti-pitching device 18 for intermodal semitrailers 5 destined for use as road trailers but also transportable on railway cars 8, of the type provided with a loading pit 40.
- the semitrailer 5 comprises a vertical pivot 1 projectingly borne on a flat face 2 of a front part 3 of its frame 4, which front part 3 is destined to couple superposingly with a conventional fifth wheel located on the back of a road haulage vehicle (not illustrated) by means of said vertical pivot 1; this to allow articulation of the haulage vehicle and the semitrailer 5 during road use.

Abstract
Description
- The invention relates to an anti-pitching device for intermodal semitrailers (destined both for use on the road and for loading on railway cars), during transport on railway cars.
- The semitrailer comprises a vertical pivot projecting from a frontal part of the trailer frame, which pivot is associable with a fifth wheel of a hauling vehicle; the above-mentioned association provides a vehicle-trailer articulation necessary for transporting the semitrailer by road. A railway car exhibits means for fixing containers to the car, comprising spikes for blocks affording engagement holes for the spikes.
- Railway cars are usually equipped for receiving various types of load, among which are semitrailers also equipped for road use and usual unwheeled containers.
- To fix the front of the semitrailers to the railway car a special housing is provided for the semitrailer articulation pivot, while the back end of the semitrailer, though its wheels are housed in a special loading pit fashioned in the car floor, is free to oscillate and tilt, obeying the properties of the semitrailer suspension, when the car negotiates a curve in the railway track.
- Containers, on the other hand, can be solidly constrained to the railway car by means of a system of spikes engaging in shaped holes in fixing blocks exhibited by the containers themselves.
- Anchoring the semitrailers in the loading pit has however proved to be effective, except where the width of said semitrailers is between 2.5 metres and 2.6 metres on lines not equipped to tolerate such measurements. The above drawback is due to the fact that the semitrailers, particularly if they are refrigeration-plant-equipped, or in any case wheeled trailers, tend to tilt during transport around curves, and their main sections are therefore liable to exceed the legally-set width limits for transport on certain lines.
- A further drawback is represented by the fact that with respect to the railway tracks the loading pit is higher than the fixing spikes for the containers: this means that containers loaded on to the cars (due to legal container height limits) have to be vertically shorter than would otherwise be possible, leading to a loss of transportable volume.
- The document FR-A-2534870 discloses an anti-pitching device for intermodal semitrailers during transport on a railway car, according to the preamble of
claim 1. - The railway car is provided with means for fixing a container, said means for fixing normally are constituted by spikes.
- The anti-pitching device comprises blocks affording engagement holes for the spikes, and further comprises four rigid supports bearing the blocks, which supports are rigidly constrained to the frame, and are distributed on the two opposite sides thereof. Two of said supports are located on a front part of the frame.
- The aim of the present invention, as it is characterised in the claims that follow, is to obviate the above-described drawbacks.
- The invention solves the problem by providing an anti-pitching device for intermodal semitrailers comprising rigid supports bearing fixing blocks of the semitrailer to the spikes of the railway car, arranged on two opposite sides of the car and conformed in such a way as to realize rigid connections between the semitrailer and the car which at least during the semitrailer's use as a road trailer, are positioned above the face of the frame associable to the fifth wheel of the vehicle hauling said semitrailer.
- The fundamental advantages obtained by means of the present invention essentially consist in the fact of obviating the need for a loading pit in the car, and resultingly enabling all types of road semitrailer to be carried on railway cars regardless of limitations connected with load size and dimensions.
- The device of the invention affords the further advantage of permitting transport of larger-volume semitrailers, with consequent cost reductions.
- Further characteristics and advantages of the present invention will better emerge from the detailed description that follows, of an embodiment of the invention, illustrated in the form of a non-limiting example in the accompanying drawings, in which:
- figures 1A and 1B illustrate, according to respectively a vertical view and a plan view from above, an intermodal semitrailer arranged on a railway car and provided with fixing devices according to the invention;
- figure 2 is an enlarged scale of a plan view from above of the device according to the invention, indicated by X in figure 1A;
- figure 3 shows a section of the device according to line III-III of figure 2;
- figure 4 is a frontal view of the device of figure 3;
- figure 5 is an enlarged scale view of a section of the device of figure 2, made according to line V-V;
- figure 6 is an enlarged scale view of a section of the device of figure 2, made according to line VI-VI;
- figure 7 is an enlarged scale view of a section of the device of figure 2 according to line VII-VII;
- figure 8 is an enlarged-scale view of a view of the device of figure 3 seen from point D;
- figure 9 is an enlarged view of a detail of figure 3, sectioned according to line IX-IX.
- With reference to the enclosed drawings, figures 1A and 1B show that the invention largely consists in an
anti-pitching device 18 for intermodal semitrailers 5 destined for use as road trailers but also transportable on railway cars 8, of the type provided with aloading pit 40. - The semitrailer 5 comprises a
vertical pivot 1 projectingly borne on aflat face 2 of afront part 3 of itsframe 4, whichfront part 3 is destined to couple superposingly with a conventional fifth wheel located on the back of a road haulage vehicle (not illustrated) by means of saidvertical pivot 1; this to allow articulation of the haulage vehicle and the semitrailer 5 during road use. - The railway car 8 further comprises conventional fixing means, typical of such devices for constraining containers, provided with
spikes 10 for blocks 9 (figures 3 and 9) exhibitingengagement holes 14 for saidspikes 10. - The
anti-pitching device 18 comprises fourrigid supports 11 bearing theblocks 9, which supports 11 are constrained to theframe 4 and distributed on the twoopposite sides 19 thereof. - Two of the four
supports 11 are located on thefront part 3 of theframe 4 while the remaining twosupports 11 are located at theback 41 of theframe 4 on a reinforcingcrossbar 42 on saidframe 4. - The
front supports 11 are conformed such that theblocks 9, at least during road circulation of the semitrailer 5, can be removed totally above theface 2 of theframe 4. - Figure 3 shows in greater detail that the
device 18 comprises aflange 15 for constraining thesupports 11 during railway use of thedevice 18, whichflange 15 can be removed from theface 2 of theframe 4 before the semitrailer 5 is used on the road, at least in cases where the supports 11 due to their mass cannot be stably lodged above theface 2 and removably from theframe 4. - The solution in which the
flange 15 is removable preferably comprises ahorizontal pivot 16 borne by theframe 4 of the semitrailer 5, on which pivot 16 afirst end 151 of theflange 15 for fixing thesupports 11 is hinged such as to be rotatable from a first work position corresponding to the condition of the semitrailer 5 when transported on a railway car 8 in which asecond end 152 of theflange 15 is associated to means 17 for blocking interacting between theflange 15 and theframe 4, to a rest position of theflange 15 corresponding to the semitrailer 5 condition when in road use, angularly rotated with respect to thepivot 16, in which thesupports 11 are located above theface 2 of the frame 4 (figure 1) while thesecond end 152 of theflange 15 is correspondingly engaged bymeans 23 for holding said flange in the rest position. - The
flange 15 is further provided with aguide 33 for sliding along thepivot 16 such that theflange 15 can be translated (see figure 2) horizontally between avertical plane 20 passing through the work position and the rest position of saidflange 15 and avertical plane 21 intermediate to thevertical plane 20 and thehalfway line plane 22 of the railway car 8 at which position theflange 15 and therelative support 11 are contained internally of the outline of the semitrailer 5 during turning manoeuvres in road use. The angle of curvature of the maximum road turning manoeuvre (with thepivot 1 as the centre point) is indicated by R in figure 2. - In figure 6 it can be seen that the means for blocking 17 comprise a
bolt 24 shaped to fit into a through-cavity 25 made at thesecond end 152 of theflange 15. Thebolt 24 is slidably borne by aguide 26 on theframe 4 having an interruptedcentral portion 27 in which, in said work position of theflange 15, thesecond end 152 of theflange 15 is inserted in alignment with thecavity 25, with theguide 26 staying engaged by drawing the bolt home through theguide 26 and thecavity 25. - The means for constraining 23 the
flange 15 comprise astructure 28 for holding, together with theflange 15, the supports 11 in their rest position. - The
structure 28 is interconnected with theframe 4 and is provided withhorizontal rest elements 29 having an angular profile and a flatvertical element 32 for horizontally contacting thesupports 11. - The
rest elements 29 and the vertical element 32 (figure 8) are associated to apawl 30 borne by thevertical element 32 superiorly to therest elements 29 and rotatable about ahorizontal pivot 31 oscillatingly about a stable equilibrium position. - The
pawl 30, when in a raised position, allows free transit of thesupports 11 so that they can locate on therest elements 29 of thestructure 28, while it interferes, when in the lowered position, with thesecond end 152 of theflange 15 such as to prevent extraction of thesupports 11 from thestructure 28. - Figures 3 and 5 show that the
sliding guide 33 exhibits a much greater breadth than thepivot 16 such as to permit theflange 15 to be translatable with respect to theframe 4 perpendicularly to therotation axis 161 of saidpivot 16 to enable greater ease of insertion of thesupports 11 on therest elements 29. - Preferably the
device 18 further comprises anarm 34 hinged to thepivot 16 at saidfirst end 151 of theflange 15. Thearm 34 is hinged to theflange 15 at an intermediate pivot 36 (figure 7). With this connection system the arm 34 (figure 7) permits of positioning thesupports 11 in the rest position, starting from the work position of theflange 15, with two successive rotation movements, a first of which is described together by theflange 15 and thearm 34 which rotate together about thepivot 16; the second rotation movement is effected by theflange 15 which rotates with respect to thearm 34 after thearm 34 has reached a limit position determined by the strike of thearm 34 against thewalls 43 of ashaped recess 44 afforded in theframe 4 of the semitrailer 5.
