Definitions

  • the invention relates to a transport and loading / unloading system consisting of a plurality of wagons and loading / unloading stations of road vehicles, parts of these vehicles or more generally road loads on the wagons of a vehicle.
  • rail train in the context of combined rail / road transport also known as alternative transport.
  • the invention also relates to the loading / unloading method using the succession of stations and wagons together forming the means necessary for this purpose.
  • containers, swap bodies, trailers or vehicles are loaded into wagons and then unloaded from wagons at railway station terminals.
  • This solution also has the important disadvantage of requiring the transport of the tractor which, if it were separated from its trailer or semi-trailer, could be used for other road transport.
  • the owners of tractors and trailers or semi-trailers are not the same and do not necessarily have the same idea of profitability of their equipment.
  • Another category of solutions more particularly intended for road containers, but also for trailers and semi-trailers concerns the handling of the road load by external means from a platform where they are abandoned by the tractor or the truck to load them into the road. a wagon.
  • This category uses equipment that is heavy and expensive to purchase, maintain and consume energy. In addition, they require the presence of a specialized operator.
  • Yet another category of solutions in which the present invention is concerned relates to the individual loading of the complete vehicle or only of its trailer or semi-trailer, and more generally of a road load, by its motive power or that which is tied to him with the help of driver of the vehicle to which it is attached.
  • One solution consists in providing a wagon with a fixed supporting structure mechanically connecting the two end platforms and carrying a movable floor that supports the road load, cf. US-A-3, 584, 584 .
  • This mechanical link carrier structure represents a consequent additional thickness contrary to the requirements of thin to exploit the maximum rail gauge down.
  • the general field of the invention is that of the rail / road combined transport systems in which the wagons comprise a pivoting railway structure carrying the road load, this carrying structure being mounted on and assembled to two end platforms carried each by a railway bogie.
  • the transport systems implementing this type of wagon differ depending on whether the ends of the carrying rail structures are releasable or not end platforms and in particular releasable both at the same time.
  • the present invention aims to simultaneously meet the two main objectives of maintaining in place the end platforms and therefore the bogies during loading and unloading operations and to make the most of the rail gauge.
  • the invention also aims to perform the loading and unloading operations without heavy equipment outside or onboard while enjoying the advantage of an energy-independent road load, that is to say that can be moved or move by its own means or by the means normally associated with it.
  • the invention also aims to allow the loading / unloading individual or selective for all cars of the same train.
  • the interesting invention must simultaneously satisfy the different conditions and requirements relating to the loading and unloading of road loads on or from railway structures, this in a minimum of time and with the greatest possible convenience for the operators, while respecting safety requirements and profitability in this mode change.
  • the invention has as a first goal to admit a road load road gauge and register the wagon carrying this road load in the rail gauge. Due to the maximum dimensions allowed by rail and road gauges, it is necessary to gain useful loading height on the wagon.
  • the underside of the railway carrier structure is thus placed as low as possible and this rail-carrying structure is made with a thin floor, in any case as thin as possible in view of the requirements of mechanical strength.
  • Another essential goal relates to the ease and speed of reinstatement of the railway carrier structure after the opening and closing maneuvers of the wagon during the loading / unloading phases and the appearance of the individual loading / unloading in parallel of the cars.
  • the bogies move because of the existence of residual forces in the couplings, in the buffers, in the suspensions and other devices. They can also move due to movements of access to, movement on and removal of the supporting structure or shocks.
  • This disadvantage is overcome by assigning to the end platforms a given position by means of retaining the ground or by keeping the spacing thereof at a constant distance.
  • An additional aim is to avoid encroaching on the useful load volume of the wagon by the presence of means and equipment for handling the load and the load-bearing railway structure. These means would clutter up the wagon and would require embedded auxiliary energy sources.
  • the road load moves by its own means during the loading and unloading phases and the power actuators required for maneuvers are external to the wagon and powered by external sources.
  • This energy independence between the wagon, the load and the actuating means makes it possible to lighten the wagon and to simplify the distribution of the energy.
  • the motor means are on the railway infrastructure and on the road load or its tractor.
  • Yet another object is to limit the useful driving stroke of the lifting means of the carrying railway structure.
  • any additional length of the stroke of the release means for example by lifting, generates new, much larger efforts resulting in an additional cost of energy consumed and an oversizing of the equipment.
  • the lifting movement of the load-bearing railway structure after having compensated for the overwriting of the suspensions, continues with a useful stroke of small amplitude, just necessary to dissociate the links between the railway bearing structure and the platforms.
  • end forms for example the release of the ends of the supporting structure from their housing in or supported on the end platforms.
  • Another additional object relates to the passage of tensile forces. These must be supported entirely by the supporting structure and its connections with the end platforms to avoid the use of an additional lower structure of great mechanical strength representing a significant overweight and extra thickness.
  • the present invention uses the carrier structure to transfer tensile forces to the other end of the car.
  • the purpose of the invention is to place the wagons of the trainset in an appropriate position with respect to the equipment of the track and of the wharf so as to be able to easily and rapidly implement the loading / unloading means.
  • the invention also aims to achieve a particularly resistant car, not only to all the efforts it can endure during its operation, but also to all the exceptional efforts related to loading and unloading operations and maneuvering major loads such as those of road freight vehicles.
  • the invention also aims to propose a load-bearing railway structure in which the load between its own means, this carrier structure is back in place on the wagon by a means of support outside the wagon and independent energy thereof.
  • the invention simultaneously aims for all the aforementioned purposes and provides a comprehensive and reliable overall solution that overcomes the majority of disadvantages of previous achievements.
  • the invention relates to a combined rail / road transport system formed of at least one railroad track, wagons and loading / unloading stations, characterized in that each wagon is composed of two platforms of end and a railway structure carrying a road load pivotally mounted on the wagon and connected to the end platforms by separable and lockable connections of rigid assembly and that each station is equipped with the ground and the level of each loading / unloading location of at least one lifting and lowering means and at least one pivoting drive means of the supporting structure allowing dissociation and pivoting towards the platform, the latter being equipped recovery and reception means for continuing pivoting on the platform, the assembly comprising means for retaining the position and presentation of the end platforms, in which position they are when the wagon is in the dissociated state.
