Definitions

  • the invention relates to a device as described in the introduction to patent claim 1.
  • sensor elements are attached directly to the rails by bonding or welding.
  • the rails must first be cleaned and the sensor element mounting surface carefully ground to ensure that it is even. After grinding, the sensor element mounting location is marked off in the neutral plane and is cleaned thoroughly.
  • the sensor elements are attached by bonding or welding, and are then connected electrically. Following connection, the elements and connection points are provided with moisture protection and physical protection.
  • the mounting operation must be carried out with great care and in good weather conditions, which may be difficult to assure outdoors.
  • the alternative is to prefabricate the rails, with the sensor elements attached, in the factory, which causes major disruption to rail traffic when the prefabricated rails are subsequently laid on the track. The same problems arise in the course of tracklaying and track maintenance work.
  • the present invention relates to a sensor device for indicating static or dynamic load, preferably from railbound vehicles.
  • FIG. 1 Examples of the mechanical arrangement, electrical arrangement and installation are shown in Fig. 1, Fig. 2 and Fig. 3 respectively.
  • the sensor beam consists of a base (1) with strain gauges (2) attached, together with moisture protection as well as physical protection.
  • the sensor beam is mounted on the object in which the load is to be measured by means of bolts and nuts or, alternatively, by bonding or welding.
  • the resultant deformation of the rail is transmitted to the beam, whose sensor element registers the deformation and converts it into an electrical signal.
  • Fig. 3 shows two sensors, one mounted on each side of the web. This operation can normally be carried out without disruption to rail traffic; mounting of the sensor can be carried out very quickly and the work can be completed regardless of the weather.

Abstract

Des éléments capteurs sont fixés ou soudés directement sur les rails, puis reliés électriquement, opération accomplie sur site ou bien intégrée en aval pendant la préfabrication des rails à l'usine. Les procédés impliquent un travail considérable sur la voie, et son exécution perturbe ou est perturbée par le traffic ferroviaire. On rencontre les mêmes difficultés au cours de la pose et de l'entretien des voies. La solution décrite dans l'invention est caractérisée en ce que des barres formant capteur sont fabriquées à l'avance et montées sur les rails à l'aide de boulons et d'écrous.
