Definitions

  • the invention relates to a method for generating electrical signals on railroad tracks, which are triggered by the wheels of rail vehicles, and which are required for the control of technical equipment on the track and / or at level railroad crossings and / or in signal boxes, or in technical equipment are used for the purposes of counting and / or switching and / or measuring gates and / or for determining the physical properties of the wheel and / or the wheelset and / or the bogie and / or the vehicle from which the track is currently being driven; and a device for performing the method.
  • Optical devices are made unusable again and again due to constant contamination by train operation and the influence of weather-related influences, such as fog and snowfall. Furthermore, it is also disadvantageous in these methods that the electrical and / or mechanical functional units have to be readjusted or re-calibrated again and again, which in some systems can only be successfully carried out at certain outside temperatures.
  • the invention has for its object to overcome these disadvantages and to provide a measuring method and a device for its implementation, which responds exclusively to the physical effects of the wheels of rail vehicles on the rails and generates signals that are essentially only those of the wheel depend on the generated rail deformation.
  • This method creates the possibility of realizing speed-independent and axially symmetrical measurement signals, such as those in general in the above-mentioned applications and in stationary wheel set measuring systems on the track, such as for measuring wheel set bearing and wheel tire temperatures, wheel flat points, wheel weight, wheel profile, profile and Speed monitoring systems in particular are absolutely necessary.
  • FIG. 1 four rails are shown with 1 in cross-section, to which the strain gauge systems 4b, 5b are attached in different ways. Namely in the drawing from left to right with a welded connection, with a screw connection by means of a rail bar screw 3, with a welded-on strain gauge support plate 2, and with a screwed-on strain gauge support plate 2, which is clamped between the rail foot and the rail head.
  • a plurality of strain gauge systems can be mounted on a carrier plate 2, which are then designated 4b and 5b, respectively.
  • the signals are passed from the strain gauge systems 4b, 5b to a cable distributor 6, to which a connecting cable 7 is connected, which establishes the connection to an electronic cable distributor 30 (FIG. 3).
  • a plurality of distributors 30 can be connected in series in a feed line to an electronic evaluation unit.
  • a plurality of double strain gauge systems can be attached to the rails 1, either within a sleeper compartment 1a opposite each other on both rails, one system 25, 26, or on the same rail as one behind the other in different sleeper compartments Systems 27.28.
  • strain gauges 4b, 5b The interconnection of two strain gauges 4b, 5b to form a measuring bridge ensures higher switching reliability and accuracy.
  • the inventive method and the proposed device for its implementation can be used because of its insignificant electrical influence on railway lines with all known superstructures and preferably on routes with electrical train.
