Definitions

  • the invention relates to a train sensor for warning people in the track area.
  • Train sensors for warning people in the track area against approaching trains are known, the signals of which are used for warning purposes are routed via a message channel to warning stations located in the work area of people and which issue a warning in accordance with the signals (LENGEMANN, From detection to alarm - the future rot warning at the Deutsche Bureaubahn "in electric railways, 1983, H.6, p.204-209; DE-AS 1 755 589).
  • Inductive sensors or vibration sensors are called.
  • Vibration sensors are unsuitable
  • a mechanic has to laboriously adapt the inductive sensors to the type of rail, mount them on the rail and adjust them, and the mechanic himself has to warn of the approaching trains In the case of slowly moving construction sites, this necessary safeguard no longer provides the benefit of a warning system, and inductive sensors are also susceptible to magnetic fields from brakes and drive currents, and it is not possible to detect wheels made of non-ferrous metal.
  • a pneumatic train sensor is known (SIEMENS: Elektrotechnik im railway operation, S44 rail current closer, SH 3226 / 2561.5 T ES), one has 4 pressure claws attached to the rail pressure chamber, with Driving over a pulling wheel creates a pressure in the pressure chamber via a The hose is electrically isolated from a membrane contact that detects the tension becomes. Installation and time-consuming adjustment must be carried out in the danger area will. There are no means to control the fall of the tension sensor from the rail called.
  • Measuring devices for determining the weight of railway vehicles are known from DE-PS 822 019, the deflection of the rail being measured as a result of the weight on the train wheel with a pressure chamber screwed to the rail foot.
  • the pressure changes can act directly on control devices.
  • the nearest sleepers are fixed and stiffened for the correct functioning of the pressure chamber. But the scripture does not address what is known from it Weight measurement principle "to apply to a device for warning people. Safety principles are not specified.
  • the object of the invention is to provide a tension sensor, the signals of which it it is possible to warn people in the track area of approaching trains, whereby the Train sensor has the required security and can be installed safely and quickly can be.
  • the tension sensor is simply constructed. To assemble you do not have to Keep the danger zone open, as there is no need to screw it onto the rail. A Adjustment in the danger zone is not necessary.
  • the Monitoring the pressure ensures detection of failure or failure dangerous removal of the tension sensor.
  • Guides on the top of the train sensor prevent slipping sideways.
  • a travel rail 1 is supported by sleepers 3 on a substructure 2.
  • both the running rail 1 and the sleepers 3 and the substructure 2 under the sleepers 3 are loaded.
  • the distance of the rail foot to the substructure 2 changes most in the middle between the sleepers 3 and is significantly greater than the deflection of the running rail 1 alone.
  • This property is used in the tension sensor for obtaining trouble-free, large pressure changes in pressure chambers 21, 41 by pushing the pressure chambers 21, 41 in at this point.
  • the pushing in of the pressure chamber 21, 41 under the rail foot can be done with a handle in a depressurized cylinder and without exposing itself to any danger.
  • the pressure chamber 21, 41 is then filled until the desired pressure is established, or the pressure chamber 21, 41 is clamped non-positively between the foot of the travel rail 1 and the substructure 2. An attachment to the rail is not necessary. An adjustment to the rail type and an adjustment is not necessary.
  • the remaining components 13 of the train sensor are expediently combined in a housing located away from the track; they are not electrically connected to the running rail 1 and are therefore not exposed to disturbances from drive currents and magnetic fields.
  • the pressure chamber 21, 41 is connected to a pressure sensor 23, 43 via a pressure hose 27, 47. Electrical signals 31, 51 are present at the pressure sensor in proportion to the pressure in the pressure chamber 21, 41, which are fed to an evaluator 5 a, 5 b.
  • the pressure signals 31, 51 change positively when the pressure chamber 21, 41 is loaded by a pull wheel. When the load is relieved after driving over, there is a negative change in the pressure signal 31.51. These pressure changes are evaluated as a wheel signal by the evaluator 5a, 5b if the pressure change exceeds a value of a pressure change 7 given to the evaluator 5a, 5b at its input, either in a positive or negative direction; this protects against disturbances and pediatric interference.
  • the positive pressure change is preferred because it also detects stationary traction wheels.
  • a wheel signal recognized in this way is passed in a known manner by the evaluator 5a, 5b via a wired or wireless message channel 11 to warning stations 15, which emit a warning 17 directly or indirectly according to the signals of the message channel 11 to the persons to be warned in the track area.
  • a train sensor 21, 41, 13 can, for example, announce the train, another train sensor 21, 41, 13, not shown, in the vicinity of the persons to be warned can de-register the train by both train sensors acting on the warning station 15.
  • a revolving counter 10 can count the wheel signals and the evaluator 5a, 5b Submit payer status via message channel 11. In this way, trains can be recorded more precisely.
  • the direction of pull can also be detected by the evaluator 5a, 5b by the evaluator 5a the wheel signals from the train sensor 21, 23 and the evaluator 5b the bath signals from adjacent tension sensor 41,43 detected.
  • the time sequence of the wheel signals is a measure of the direction of the train which the evaluator 5a, 5b delivers directly to the message channel 11 or linked as a sign with the counter reading 10.
  • train sensors 21, 41, 13 complex track diagrams during the detection be ruled by trains.
  • the safety-relevant parts 23, 5a and 43.5b of the tension sensor are expediently closed double and the results of the evaluator 5a with those of the evaluator 5b over a Compound 6 to compare in time, with a waiting period 8 at the entrance of the Evaluator 5a, 5b is specified.
  • the evaluator 5a, 5b determines an inequality after the waiting period 8 and enters Fault signal to the message channel 11.
  • a tension sensor can be used in the same way secure with only one pressure chamber 21, this pressure chamber with both Pressure sensors 23 and 43 is connected (not shown).
  • the assembly is much easier if the pressure chambers 21, 41 and Pressure sensors 23.43 with closable filling openings 25.45 for a liquid or gaseous medium are connected and the pressure chambers 21, 41 as lifting cylinders, are preferably designed as bellows cylinders.
  • FIG. 2 shows a typical arrangement of a pressure chamber 21, 41 between the foot of the running rail 1 and the substructure 2.
  • Guides 64 on the upper side of the pressure chamber 21, 41 adapted to the foot of the travel rail 1 prevent the pressure chamber 21, 41 from slipping sideways and further facilitate assembly.
