京广高铁接触网定位器、定位支座钩环连接部位异常磨损分析

Study of Abnormal Wear of Connection Locations between Steady Arm/Steady Seat and Hook Ring for OCS of High Speed Railway

随着高铁运营时间逐渐递增,近年来在检修中发现接触网定位器、定位支座钩环连接部位出现异常磨损。本文针对京广高铁(武广段)接触网定位器、定位支座钩环连接部位异常磨损缺陷进行分析,对缺陷数量集中的正定位装置探究磨损缺陷成因,并提出针对性整治措施。

Along with gradual increasing of operational time of high speed railway;the abnormal wear of connection locations between steady arm/steady seat and hook ring are found during inspection and maintenance. The paper analyzes the defects of abnormal wear of connection locations between steady arm/steady seat and hook ring of OCS in sections of Wuhan-Guangzhou high speed railway, the paper studies in details the causes of the wear defects of pull off registration devices which have concentrated defects of wear, and puts forward the corresponding rectification measures accordingly.
