Definitions

  • the invention relates to a device for monitoring the temperature of the wheelset bearing of passing rail vehicles, comprising at least one located below the rail track in a housing and connected to an evaluation IR receiver unit, wherein the housing is used supporting at least two attenuators in a threshold is.
  • these housings are not connected directly, but via at least two attenuators each with the measuring or hollow threshold, which may consist of rubber, plastic or are formed by steel springs and have a stroke of about 2 to 4 mm. This avoids that the vibrations that always when crossing a wheelset on the measuring or hollow threshold arise, not or only to a limited extent on the IR receiving units are transmitted, which are sensitive components and can be damaged or destroyed by these vibrations.
  • the measuring or hollow threshold which may consist of rubber, plastic or are formed by steel springs and have a stroke of about 2 to 4 mm.
  • IR receivers are being checked for proper functioning about every 6 months. With regard to defective vibration dampers, this period can clearly be too long. Defects on the vibration dampers may already be present prior to installation or even occur during installation or at a later time. However, a faulty vibration damper involves the risk that the associated IR receiving unit occasionally fails over a shorter or longer period of time without being able to detect the actual cause. This can then lead to damage or destruction of the IR receiving unit and / or to erroneous measurement results.
  • the invention is therefore based on the object, a device for monitoring the temperature of the axlebox of passing rail vehicles in such a way that a defective or not working properly vibration damper can be detected immediately and thus excluded damage or destruction of the IR receiver and resulting erroneous Measurement results are avoided.
  • the housing is also associated with a connected to the evaluation unit acceleration sensor.
  • the housing associated acceleration sensor it is possible to detect faulty vibration immediately by the measured acceleration values with The values stored in the evaluation unit are compared and impermissible deviations are immediately communicated as an alarm signal from a monitoring center.
  • the acceleration sensor can be arranged either in the housing or on the housing.
  • a rail vehicle for example a wagon, of a wheel set thereof.
  • the wheel 1 runs in the direction of rotation of the arrow 4 on a rail 5, which in turn is supported by a plurality of sleepers 6.
  • Each wheelset bearing 3 is associated with an IR receiving unit 7, which is located in a closable housing 8.
  • the housing 8 is in turn at least partially inserted into a recess 9 of a designed as a measuring or hollow threshold threshold 6a.
  • the housing 8 is supported for example via four attenuators 10, of which only two attenuators 10 can be seen in the drawing, on the top of the threshold 6a.
  • Attenuators 10 are made of elastically adjusted rubber or plastic or are formed by steel springs and have a stroke of about 2 to 4 mm. These attenuators 10 have the task to preclude that the inevitably occurring during the crossing of a car on the threshold 6a vibrations in a disturbing manner via the housing 8 to the therein and sensitive to vibration components, in particular to the housing 8 located in the IR Receive receiving unit 7 and bring here adverse consequences. These consequences may be that the IR receiving unit 7 occasionally fails for a shorter or longer period of time or is destroyed and / or supplies incorrect or incorrect measurement results to an evaluation unit, not shown. It may now occur in practice that one or more attenuators 10 is defective or defective. Such a defect may already be present prior to installation, during installation or occur at a later date.
  • a per se known acceleration sensor 11 is arranged in the illustrated embodiment in the housing 8, which is also connected to the aforementioned evaluation unit.
  • this acceleration sensor 11 the attenuation of the housing 8 and thus also the vibration impinging on the IR receiving unit 7 can be measured and compared with a previously defined and stored limit value. If the stored limit values are exceeded, a signal is sent as a maintenance alarm to a monitoring center.
  • the IR receiving unit 7 and the acceleration sensor 11 are not constantly turned on and thus active.
  • the IR receiving unit 7 and the acceleration sensor 11 are activated or deactivated by rail contacts 12, 13 which, seen in the direction of travel of a train, are arranged at a distance in front of and behind the threshold 6a on a different threshold 6.
  • the acceleration sensor 11 may also be arranged on the outside of the housing 8.
