新型小曲线半径区段定位装置探索研究

Exploration and Study on Registration Device in a New Typ e of Small Radius Curve Section

普速铁路及城市轨道交通接触网通常需要在小曲线半径路段安装软定位装置。本文基于对接触网软定位的要求,列举了目前常用的3种软定位方式,分析了小曲线半径处使用软定位存在的问题,提出了一种既有弯曲外形又能限位的定位器即折角定位器,并通过现场安装试挂证明其设计的合理性。

Flexible registration devices are usually required to be installed on the OCS of small radius curve section of general speed railway and urban rail transit.The paper,on the basis of the requirements for the flexible registration device on OCS,lists out the three types of flexible registration devices,analyzes the problems existed in application of flexible registration device in small radius curve section,puts forward a type of steady arm,of curve shape and with a function of position limitation,that is an angled steady arm.The rationality of the design has been verified through site installation of the steady arm for trial service.
