Title:
OPTICAL FIBRE DETECTION APPARATUS USING STEEL RAIL AS ELASTIC BODY, AND RAILWAY OVERLOAD AND UNBALANCED LOAD DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/079986
Kind Code:
A1
Abstract:
An optical fibre detection apparatus using a steel rail as an elastic body, and a railway overload and unbalanced load detection system. The apparatus comprises a shear-force detection apparatus and a pressure detection apparatus, the shear-force detection apparatus comprising an optical fibre sensitive element (5), wherein the optical fibre sensitive element (5) is fixed on a neutral axis (4) of a steel rail through low-energy spot welding. The arrangement orientation of the optical fibre sensitive element (5) achieves the technical effects that stable shear-force waveforms are output without being interfered with by vibration of the steel rail, and the installation position facilitates grinding and welding, thereby solving the problems in the prior art that the engagement mode of the shear-force detection apparatus and the steel rail destroys the strength of the steel rail and an output curve change is caused due to being susceptible to a change in external force and temperature or a human operation factor.
