Abstract

The invention relates to the technical field of railway detection equipment, in particular to a steel-aluminum composite contact rail wear measurement device and a measurement method based on ultrasonic measurement. The measurement device includes a measurement device body and a data acquisition and processing device located in the measurement device body. The measurement The device body is suspended under the steel-aluminum composite contact rail through the boom; this measurement method combines position coordinate information and calculates the thickness of the stainless steel strip through ultrasonic waves to detect the wear of the steel-aluminum composite contact rail. The measuring device and measuring method can effectively solve the problems of inaccurate measurement and low efficiency.

Description

technical field [0001] The invention relates to the technical field of railway detection equipment, in particular to a steel-aluminum composite contact rail wear measurement device and measurement method based on ultrasonic measurement. Background technique [0002] In the operation of the catenary rail, in order to ensure the normal flow of the locomotive, it is required to measure the wear of the catenary rail at least once a year. When the contact rail of the catenary is worn to a certain extent, it should be reinforced or replaced. The local wear caused by the arc caused by the dynamic change of the contact force of the collector shoe, the wear of the contact rail is related to many factors such as the contact suspension state, the operation mode of the pantograph of the electric locomotive, the current intake state, and the hardness of the slide plate. Severe local wear may cause insufficient power supply to affect the power of the locomotive, aggravate arc discharge, a...
