Definitions

  • the invention relates to the field of railway equipment, and the present invention more specifically relates to a device for improving the safety of railroad cars, and in particular tank cars, intended for the transport of dangerous goods, in particular airframes.
  • gas so-called Class 2 tank wagons
  • IPD 2007 International Carriage of Dangerous Goods by Rail
  • tank car tanks must be protected by measures to avoid the overlap of buffers, which railcars are conventionally equipped with, and the derailment or, at least, to limit damage to the tank cars. said tanks when overlapping buffers, and possibly the chassis of wagons that support them.
  • this Regulation recommends the equipment of the tank cars concerned with an anti-overlapping buffer device, the purpose of which, in the event of a collision between two wagons causing the operation of the fusible devices fitted with the telescopic buffers, tank cars, to prevent the chassis of one of the two wagons from passing over the chassis of the other, and thus to ensure that the chassis of the two wagons remain substantially in the same horizontal plane.
  • the anti-overlap device must not disturb the normal operation of the wagon, nor the normal operation of the buffers, which are known that each of them can execute, in the event of an impact with another buffer another wagon, first a first reversible elastic telescopic race, possibly followed, depending on the importance of the shock, a second telescopic race, irreversible, corresponding to the plastic deformation of a fusible element or assembly.
  • the anti-overlap device must allow the curve crossing encountered during operation, and in particular allow the free registration of another wagon equipped with an anti-overlap device, in a curve. radius of 75 m.
  • the anti-overlap device must allow the assembly, permanent or temporary, on the wagon of other equipment such as grip handle and Bern rectangle.
  • the anti-overlap device must operate regardless of the state of load and wear of the cars it equips and involved in a shock, and the anti-overlap device must remain effective even if a car involved in a shock and other than that it is equipped itself is not equipped with an anti-overlap device, while two anti-overlap devices, each equipping one of two cars involved in a shock, must not interfere mutually, each of which must withstand a vertical effort (upwards and downwards) of 150 kN.
  • the above-mentioned Regulation specifies that the increase in the buffer overhang relative to the chassis of a wagon, and due to the fixing of the anti-overlap device, must be less than 20 mm.
  • the anti-overlap device must allow the mounting of buffers, four in number per wagon, and should not interfere with the maintenance operations on these buffers, the anti-overlap device to be provided at each buffer of a wagon, and be of width at less than the horizontal dimension of a buffer plate, except at the location of the left step at the corresponding longitudinal end of the wagon frame, where this device shall not interfere with the free space for the shunter, any covering the maximum width of the corresponding buffer.
  • the anti-overlap device must be constructed in such a way that it does not aggravate the risk of penetration of tank bottoms in the event of an impact.
  • the object of the present invention is to propose an anti-overlap device satisfying the requirements presented above of the RID 2007 Regulation, and whose structure makes it possible to prevent rather than limit the damage caused by the phenomenon of overlapping railcar buffers. tanks and possibly chassis of such wagons.
  • a claw of the hull engages the buffer associated with the wagon vis-à-vis between this claw and its associated buffer, which prevents the overlap of the frames of the two cars.
  • a claw of each of the two hulls engages between one of the two claws of the other hull and the buffer associated with said other hull, which prevents the overlap of the frames of the two wagons.
  • the invention also relates to a railway car, in particular a tank car, comprising two buffers at each of the two longitudinal ends of its chassis, each pad being able to perform a reversible elastic telescopic compression stroke and a compression stroke.

  • cords 15 material excess may be solder cords if the shell 10 is a welded assembly, or result of a manufacture by forging or molding of the shell 10.
  • Fixing the shell 10 on the corresponding crosshead 3 is provided by four orifices 16 bolting, which pass through the base 11 at the four corners of a rectangle with a vertical spacing of 160 mm and a horizontal center distance of 280 mm , to simultaneously allow the attachment of a buffer 4 corresponding, by its flange 5, against the inner face of the base 11, the outer face is applied and fixed against the corresponding crosshead 3.
  • the arcuate recesses 14 of the side gussets 13 facilitate not only the fixing of a buffer 4 inside a shell 10 and, via the base 11 of the latter, on the chassis 1 of the wagon, but also the maintenance operations on the buffer 4, whose normal operation, both for its reversible elastic travel and irreversible fuse or plastic race, is not disturbed by the shell 10.
