The invention relates to the technical field of turnout detection, in particular to a turnout fault detection device.
Turnout is a kind of line connection equipment that makes trains turn from one track to another. Usually, there are a lot of laying in stations and marshalling yards. There are many kinds of turnouts and complex structures. High-speed turnouts are characterized by high safety, high smoothness, high stability and high allowable passing speed, which ensure the smooth and comfortable operation of trains. Therefore, high-speed turnouts are all made of single turnout above No.18 and movable track frog, which is suitable for cross-section jointless track.
The common problems of turnouts include excessive scratches on the surface. If the scratches on the surface of turnouts are too heavy, they will cause potential safety hazards to the off-going trains, so they need to be detected regularly. However, the detection method of turnouts in the prior art is manual detection, and the tools used are feeler gauge, steel ruler or vernier caliper, etc. The disadvantages of manual detection are slow detection speed and inaccurate detection results. Therefore, we propose a turnout fault detection device to solve the above problems.
