1简序襄阳工务段管辖道岔共计1 713组,39种型号,其中,SC330道岔占12%,备料、配送和更换最为困难的当属SC330道岔。近10年来,由于铁路基础建设突飞猛进,产品升级步伐也不断加快,各设备管理单位既要照顾到老产品部分钢件的重伤更换,又要适应新产品的配套升级,因此,备料过程始终处于被动状态。然而,新老产品交替使用,致使道岔尖轨与基本轨互不匹配,主要体现在限位器孔距与孔数的差异,导致尖轨或基本轨单件出现伤损时,或放弃限位器安装、或尖轨基本轨成套更换、或多品种备料,不仅加重
1 Brief introduction Xiangyang Substation has a total of 1 713 groups and 39 models of turnouts under its jurisdiction. Among them, the SC330 turnout occupies 12%, and the most difficult part to prepare, deliver and replace is the SC330 turnout. In the past 10 years, due to the rapid development of railway infrastructure and the accelerated pace of product upgrading, the equipment management units not only need to take seriously the replacement of the old steel products but also adapt and upgrade the new products. Therefore, the preparation process has always been passive status. However, the new and old products are used interchangeably, resulting in mismatch between the switch rail and the basic rail, which is mainly reflected in the difference between the hole distance and the hole number of the stopper, resulting in a single piece of sharp rail or basic rail injury, or to give up the limit Installation, or rail basic rail replacement, or more variety of spare parts, not only aggravate
