Abstract

A testing apparatus for the calibration of overheating or rail brake locating devices comprises an IR emitter which is guided in a housing so that it can shift along a curved track to exhibit an appropriately adapted beaming direction in a particular position. An extension piece for the track is provided for further changing the beaming direction.

Claims

1. A testing apparatus for the calibration of overheating and rail brake locating devices, comprising:

a housing containing a curved track;

means for selectably positioning an IR emitter along said track to adjust the position of said emitter with respect to a device being tested; and

means for fixing said emitter at a selected position on said track.

2. A testing apparatus according to claim 1, wherein the housing is detachably magnetically connected to the device being tested.

3. A testing apparatus according to claim 1 or 2, wherein the housing is flat and longitudinally extended in the direction of the positioning of the emitter.

4. A testing apparatus according to claim 1 or 2, wherein the IR emitter is connected to a power circuit for the adjustment of the temperature of the emitter, the power circuit being connected to an evaluation circuit of the device being tested.

5. A testing apparatus according to claim 1 or 2, wherein at end positions in the positioning of the IR emitter elastic buffer stops are provided.

6. A testing apparatus according to claim 1 or 2, wherein when the testing apparatus is operatively positioned with respect to said device being tested, the housing is located a predetermined safe distance from a rolling train.

7. A testing apparatus according to claim 1 or 2, further comprising an extension piece joined to said curved track, said piece being adapted to receive and position an IR emitter with respect to said device being tested.

8. A testing apparatus according to claim 1, wherein the means for positioning the IR emitter is an adjusting screw.

9. A testing apparatus according to claim 1, wherein the curved track is provided with adjustably arranged stops.
