锁钩铜套磨损量探尺在ZYJ7型道岔维护中的应用

Application of the Gage Rod in the Maintenance of ZYJ7 Turnout for Measuring the Wear of Lock Hook Copper Sleeve

为了实现对ZYJ7型道岔锁钩铜套磨损量判定的一致性,制作了针式锁钩铜套磨损量探尺。介绍探尺的结构、参数及其功能。现场试验和近1年的应用表明,利用针式锁钩铜套探尺,可准确判断铜套磨损量,有效避免因锁钩铜套磨损量超标引起的道岔故障。

In order to realize the consistency in judging the wear amount of lock hook copper sleeve in ZYJ7 turnout, the authors make the pintype gage rod for measuring the wear space of lock hook copper sleeve. The au thors introduce the structure, parameters and functions of the gage rod. The field test and application in the past 1 year show that using the pintype gage rod can accurately judge the wear of the copper sleeve, effectively avoid the turnout failure due to excessive wear of lock hook copper sleeve.
