Description

[0001] Gauge for measuring the conductor rail position (3rd rail) horizontally and vertically to the running rail, without contact under operating voltage and saving the measured values ​​on a handheld device.

[0002] The aim is to manufacture this measuring device made of non-ferrous metal using laser sensors (measurement accuracy: + / - 0.5 mm) so that the rail can be measured horizontally and vertically using a non-contact measurement.

[0003] The measuring device is non-metallic and has a short-circuit value of 10 kV.

[0004] The measured values ​​are stored in a handheld device and then transferred to a PC for further processing.

[0005] The minimum distance between moving parts and the current-carrying rail is greater than 500 mm.

[0006] The gauge is powered by a rechargeable battery to measure the vertical and horizontal position and to supply the evaluation device.

[0007] The main components of the gauge consist of a fiberglass profile; the length and height of the gauge vary according to the applications of the metro system, as these vary worldwide.

[0008] Detailed drawings will be provided for realistic application in Germany after testing of the prototype. Individual parts with short description: 1 horizontal support tube 2 vertical support tube 3 Support plate with stop bolt 4 support plate 5 (a / b) carrying handles 6 Battery holder 7 Holder for laser sensor - horizontal measurement 7a Laser sensor - 1 8 Holder for laser sensor - vertical measurement 8a Laser sensor - 2 9 Adapter plug evaluation unit 10 Evaluation unit

Claims

[1] Non-contact measuring device using laser technology [2] Non-metallic measuring device so that measurements can be made under current [3] By using laser technology, a measuring accuracy of + / - 1 mm is achieved [4] Measurement and storage of data under voltage during operation [5] Simultaneous measurement in vertical and horizontal position
