    • B61K9/06—Detectors for indicating the overheating of axle bearings and the like, e.g. associated with the brake system for applying the brakes in case of a fault by detecting or indicating heat radiation from overheated axles

Definitions

  • the invention relates to a device for the contactless detection of overheated parts, e.g. Axle bearings, brakes, wheel tires on passing rail vehicles.
  • overheated parts e.g. Axle bearings, brakes, wheel tires on passing rail vehicles.
  • Monitoring devices for those parts of moving rail vehicles which are heated by the moving load are known. These devices monitor the temperature of certain vehicle components by measuring the temperature dependent infrared radiation emitted by these components. Methods and devices for carrying out such measurements are e.g. described in DE-PS 23 43904, EP 0 041 178 A1 and also in US-PS 4,820,057 and the other literature cited therein.
  • the infrared detector is therefore part of the scanner attached to or on the rail.
  • the invention has for its object to provide a measuring device of the type mentioned, which overcomes the disadvantages listed above, i.e. a device in which the detector and the subsequent electronics are removed from the area of the rail and are thus arranged to be shock and vibration-proof and are shielded from interference fields.
  • the problem is solved in that the scanner with the infrared optics on the one hand and the infrared detector with its subsequent electronics on the other hand are arranged spatially separate from one another and at least one in the wavelength range of between these components for the transmission of the collected IR radiation from the infrared optics to the infrared detector approx. 2 to 12 micrometers of infrared light-conducting fiber is provided.
  • a device constructed according to the invention has the following advantages: The scanner volume and weight are significantly reduced.
  • the sensitive and expensive optoelectronics is spatially clearly separated from the area of influence of sharp environmental conditions (shock, vibration, risk of destruction due to hanging parts of passing rail vehicles, etc.).
  • the device is independent of the distance between the scanner and the rail electronics Significant reduction in the effort for amplification, conversion and measurement electronics as well as the necessary protective measures (shielding, filtering, electrical isolation, etc.).
  • FIG 1 denotes the rail on or in the immediate vicinity of which a scanner housing 2 is attached.
  • the latter contains a single-lens or multi-lens infrared optic 3 suitable for the selected radiation band, which is directed directly via a deflecting mirror 4 to the heat target to be detected.
  • This heat target can e.g. be: the axle bearing 5a of the wheel 5 of a rail vehicle, which is not otherwise shown, furthermore the tire 5b of the wheel 5 (in the case of shoe braking) or the brake discs 5c (in the case of disc braking).
  • the electrical output signals of the infrared detector are fed to a preamplifier 14 and processed further in a known manner by evaluation electronics 15.
  • Your exit surfaces 16a; 17a; 18a are combined in the rail electronics along a radius. With the interposition of one or more focusing optics 16 '; 17 ′; 18 ', these exit surfaces face a scanning deflecting element, which e.g. a wobble mirror 19 (Fig.2a) or a rotating reflective polygon 20 (Fig.2b).
  • a scanning deflecting element e.g. a wobble mirror 19 (Fig.2a) or a rotating reflective polygon 20 (Fig.2b).
  • the scanning deflection element now successively reflects those from the exit surfaces 16a; 17a; 18a emerging IR radiation of the fibers 16-18 via a further single or multi-lens Focusing optics 21 on the infrared detector 22.
  • the infrared detector 22 is followed by a preamplifier 24, the output signal of which is passed to an association electronics 25. Information about the respective position of the scanning deflection element 19 or 20 is also supplied to this assignment electronics.
  • Fig. 4 shows that at the outputs 16 ⁇ , 17 ⁇ , 18 ⁇ of the assignment electronics 25, which are clearly assigned to the fibers 16, 17, 18, the temperature-analogue output signals are now present in the correct time and place, which are separated in a known manner can be further processed.
