Definitions

  • the present invention relates to the railway field, and more particularly, to the field of guiding work equipment along a railway train.
  • the present invention relates in particular to a train set with a guidance system for guiding work equipment, in particular a crawler or wheeled construction machine such as a construction excavator, a lifting platform machine and the like, on the train. , as well as on a combination of such a train set and working equipment.
  • work equipment in particular a crawler or wheeled construction machine such as a construction excavator, a lifting platform machine and the like
  • guiding and support devices comprising two lateral running rails, fixed along the length of each wagon, on which the running means work equipment can roll while being guided.
  • the present invention aims to resolve the aforementioned drawbacks of the guidance devices of the prior state of the art, by proposing a guidance system allowing safer guidance of work equipment along a railway train, in particular avoiding the risk of derailment of work equipment, more precise in use, easier to use and less expensive.
  • the term “minimum lift length” is understood to mean the minimum distance, during the movement of the work equipment, between the two end points, in the longitudinal direction, of contact between the working equipment. means of mobility and a wagon. In practice, this minimum distance will be that at the moment when, after the work equipment has started to leave a first wagon and is therefore located in part cantilevered with respect to the latter, the means of mobility of the The work equipment is about to reach the second wagon.
  • the lift length will therefore be the length of the part of the caterpillars which is still in contact with the first wagon.
  • the means of mobility are wheels, then they must be at least three axles and the lift length will be the distance between the wheels of the axle closest to the edge of the first wagon and the axle on the further from said edge.
  • the length of the tracks will be at least twice the inter-wagon distance and that, in the case of a wheeled machine, the means of mobility will include at least three axles, the center distance between the front axle and the following axle and the center distance between the rear axle and the axle just before the latter will be at least equal to the inter-wagon distance.
  • the distance between the two bearing surfaces of the same pair, in particular their centers, being equal to the track of the work equipment, so that the means of mobility can also run on the two bearing surfaces of a first wagon before reaching the two corresponding bearing surfaces of the following wagon.
  • the inter-wagon distance will in principle be the distance, measured in the longitudinal direction of the train set, between the edges of the bearing surfaces of two successive wagons.
  • the train will be intended to run on railways which will present curves, so that the values of the distances defined in the following paragraph may be caused to vary when the train takes a curve: the distance will decrease on the inside of the curve and it will increase on the outside of the curve. Therefore, when sizing the guidance system of the present invention, those skilled in the art will have to take into account the tracks on which the train is intended to run, so that even in the curves in which the work equipment is intended to work, the inter-wagon distance as defined above or, on the outside, less than the minimum bearing length of the work equipment.
  • the present invention also aims to provide a guidance system which does not modify the dynamic behavior of the wagons, so that the wagon equipped with the guidance system according to the present invention can benefit from the certification granted to the base wagon. This is in practice very advantageous since such certification, compulsory for the train to run on a railway line, is expensive and complex.
  • the subject of the present invention is therefore a railway train set with a guiding system for guiding work equipment on the train set, the train set comprising at least two successive flat wagons each comprising a floor on which the work equipment is able to run, 'work equipment comprising for this purpose mobility means which offer, in use, a minimum length of lift which is greater than the inter-wagon distance of the train set, the system comprising first guide means integral with each of the wagons and second guide means able to be integral with the work equipment and able to cooperate with the first guide means in at least two contact locations spaced from one another in the longitudinal direction of the wagon, the train being characterized in that the first guide means are formed, for each wagon, by a single longitudinal guide which is positioned on the longitudinal axis of the floor of the wagon and extends over the length of the wagon, two ends of two consecutive guides thus being facing each other and at a distance from each other called the inter-guide distance, the second guide means being configured so that said at least two contact locations are spaced apart by a distance greater than said inter
  • Such a guiding system with a single central guide per wagon is simple to implement, inexpensive, reliable and precise in use.
  • a central guide makes it possible to guide with precision any work equipment comprising guide means capable of cooperating with the central guide, namely both a tracked machine and a wheeled vehicle, since the means mobility of the latter can roll directly on the floors of the wagons, guaranteeing the position of the equipment on the wagons and thus avoiding the risk of the equipment falling.
  • each guide can be of variable length, in particular by being telescopic at each of its two ends.
  • the energy of an impact can thus be absorbed by the retraction of the telescopic guides, preventing damage to the latter.
  • each guide could comprise a longitudinal main body of fixed length having two ends to each of which is slidably connected an end body also of fixed length, so that each end body is able to slide between a deployed position, in which it extends cantilevered from the floor of the wagon, and a retracted position, on the outside or inside of the main body, in which it has been moved towards the center of the wagon, being provided with elastic biasing means, such as a spring, one end of which bears on the main body while the other end bears on the end body, which elastic biasing means urges each body of end to the deployed position.
  • elastic biasing means such as a spring
  • Each flat wagon W comprises, in a conventional manner, a frame, traction elements, a floor P, and at each end a pair of buffers T.
  • the guide system 1 comprises first guide means 2, integral with the wagons W, and second guide means 3 able to be integral with the work equipment E and to cooperate with the first means guide 2.
  • the guide 20 is formed by a profile with a rectangular cross section, which has two longitudinal ends 21. More particularly, the profile thus comprises two first opposite sides 22 of a first width and two opposite sides 23 of a second width arranged perpendicular to the first sides 22, the second width being greater than the first width.
  • the guide 20 has its ends 21 cantilevered with respect to the floor P of the wagon W.
  • the two ends 21 of the longitudinal guide 20 project horizontally. on either side of the front and rear transverse edges of wagon W.
