Abstract

The invention relates to the field of urban rail transit, in particular to a third rail abrasion detection device and method. The device comprises a train body, a support and a non-contact detection device. A first moving part and a second moving part opposite to each other are included; the train body can cross two walking rails and the first and second moving parts abut against the two walking rails respectively; the support is connected to the train body to form a cantilever structure; and the non-contact detection device is installed on the support. The third rail abrasion detection devicecan move along the two walking rails, in the movement process, the non-contact detection device scans a third rail to realize continuous measurement, contour information, scanned by the non-contact detection device, of the worn third rail is compared with standard third-rail contour information for calculation to obtain the abrasion quantity of the third rail.

Description

technical field [0001] The present application relates to the field of urban rail transit, in particular, to a third rail wear detection device and method. Background technique [0002] The third rail is also called the power supply rail, which refers to a track installed next to the urban rail (subway, light rail, etc.) line and used for power supply alone. It works in conjunction with the current collector (collector shoe) to provide power support for all equipment on the rail transit train. [0003] Locomotives such as subways and light rails need to rely on two running rails and the third rail for power supply to realize the operation and advancement of the train. [0004] However, this third-rail power supply mode will cause wear to the third rail, so it is very important to detect and grasp the wear of the third rail to ensure the safe operation of the locomotive. [0005] At present, for the detection of the wear amount of the third rail, it is generally detected by...
