Definitions

  • the present invention refers to a wheel translation control system in a track gauge changer, capable of measuring on the passage of a train, the necessary force to translate the wheel sets of the carriages from one gauge to another.
  • Patent EP-A-O 611 847 describes a gauge changer intended to permit the automatic variation of the separation between the wheels of the wheel sets, the latter being adapted to each one of two conventional gauges.
  • This changer comprises unlocking guides intended to release the wheel fastening latches in such a way that they may move transversally, passing from one gauge to another, as well as transverse translation guides, fitted between the unlocking guides and pushing and guiding the wheels when changing the gauge.
  • the present invention has developed a control system applicable to the gauge changer of said patent, by which the resistance offered by the wheel sets may be measured when translated from one gauge to another.
  • an object of the present invention consists of providing a wheel translation control system in a track gauge changer with the purpose of always knowing if said translation is made without the necessary force for it exceeding a predetermined value.
  • This value will vary according to the type of train (passenger train, goods train, mixed train), but in general should be less than 300 daN.
  • Another object of the invention consists in keeping an updated record of the resistance offered to the translation by each wheel set of a train, and hence being able to adopt the repair or reconditioning measures, necessary only for those wheel sets exceeding the above mentioned predetermined value in their translation from one track gauge to another.
  • control system applicable to a track gauge changer comprising unlocking guides, two for each side of the wheel set, running parallel to the track axis, and transverse translation guides, two for each side of the wheel sets, fitted between the unlocking guides of the corresponding side and each one of them consisting of an elastic part and a rigid part joined to each other in an articulated way at one of their ends
  • said control system being characterised in that it comprises, for each transverse translation guide, a plurality of load cells mounted in elastic sensing devices housed and fixed in the unlocking guides, as well as joined to the transverse translation guides; summing junction boxes connected to said load cells and intended to receive the signals generated by the latter on the passage of the wheel sets; a signal conditioning unit connected to said junction boxes and intended to condition the analogical signals transmitted from the latter; and a data collection and storage digital equipment to process the signals received from the load cells across the junction boxes and the conditioning unit, as well as other characteristic data referring to the vehicle and its wheel sets.
  • three load cells are used for each transverse translation guide, one arranged in the free end of the elastic part of said guide, another situated in the joining area of the elastic and rigid parts of said guide, and a third one located in the free end of the rigid part of said guide.
  • a track gauge changer 1 is fitted between rolling rails 2 of UIC gauge and rolling rails 3 of RENFE gauge (RENFE is the acronym for the Spanish Railways).
  • the installation comprises guide rails 4 intended for centering and sliding the carriages during the track gauge change operation; internal 5 and external 6 unlocking guides, intended to release the wheel fastening latches of the wheel sets and hence leaving the latter free to be transversally displaced, passing from one track gauge to another; and transverse translation guides arranged between the two sliding guides 5, 6 on each side of the track, each one of them consisting of an elastic part 7 and a rigid part 8.
  • each transverse translation guide 7, 8 has three load cells C1, C2, C3, assigned, respectively corresponding to the free end of the elastic part 7 of the guide, to the joining area of the elastic and rigid parts 7, 8 of the guide and to the free end of the rigid part 8 of the guide.
  • the load cells are installed on fixed supports of the unlocking guides 5, 6 and each one connected to an elastic sensing device 9 transmitting to said cells the forces coming from the wheel sets during their translation movement from one track gauge to another.
  • the elastic sensing devices 9 are also joined to the corresponding transverse translation guides 7, 8.
  • the forces measured by the load cells C1, C2, C3 are transmitted to the summing junction boxes 10 and from these to a signal conditioning unit 11.
  • the analogical signals conditioned in unit 11 are sent to a processing equipment 12 for their display and evaluation.
  • the load cells C1, C2, C3 When the wheels of the wheel sets of a railway vehicle enter in contact with the transverse translation guides 7, 8, the load cells C1, C2, C3 will start to measure the force imposed over said guides by the wheels during their movement of change of track gauge, the force imposed over each point of the translation guides 7, 8 being the sum of the forces measured by the load cells located on either side of this point.
  • the entrance load imposed by the wheels over the elastic entrance part 7 of the transverse translation guides is not considered. That is, assuming that the train comes from the UIC side (left side of figure 2), the measurements in the load cells C1 and C2 of the external transverse translation guides will not be taken into account (the load cell C3 of these external guides would not work in this case, since the wheels would never be in contact with the rigid part 8 thereof).
  • the control of the translation force evolution of the wheel sets in a train coming from the UIC side will be made by measuring this parameter in the internal transverse translation guides (nearer to the track axis) by means of their three respective load cells C3, C2 and C1, which will measure the horizontal reaction forces at the end of the rigid part 8 of said guides remote from its elastic part 7 (load cell C3), at the end of said rigid part 8 close to its articulation with said elastic part 7 (load cell C2) and at the end of this elastic part 7 remote from its articulation with the rigid part 8 (load cell C1).
  • the force measurement signals generated by the cells C1, C2, C3 are sent to the summing junction boxes 10, where the signals corresponding to each point of the transverse translation guides 7, 8 are added together to obtain the total force applied on the corresponding point. These sum signals are transmitted to the conditioning unit 11, where they are prepared for their transmission as analogical signals to the processing equipment 12. In the latter, the analogical signals are digitized, displayed on a screen and evaluated.
  • the processing equipment 12 should be capable of supplying, among other, the following informations:
  • control system of the present invention it is possible to have an exact knowledge of the state of each wheel set of a vehicle at all times, and to subject to revision and/or repair only those wheel sets really needing it.
