银兰客专18号道岔无交叉线岔弓网状态分析及优化

Analysis and Optimization of Pantograph-catenary Interaction of Non-crossing Type Overhead Crossing above Turnout No.18 for Yinchuan-Lanzhou Passenger Dedicated Line

目前国内高速铁路车站与正线相连股道间多采用18号道岔,接触网线岔多采用无交叉线岔布置方式。18号道岔无交叉线岔设置于车站咽喉区,是影响行车安全的重要设备,其技术参数直接影响高速列车运行安全。本文通过分析银兰客专银川至中卫段运行试验期间18号道岔无交叉线岔运行状态及存在的安全隐患,提出优化措施,可指导在建及运行线路18号道岔无交叉线岔参数调整。

At present,No.18 turnouts are mostly used for connection between station track and main line track of high-speed railway in China,and non-crossing type overhead crossings above the turnouts are normally adopted.No.18 turnout is set in the throat area of the station and it is an important equipment affecting the train operation safety,its technical parameters directly affect the operation safety of high-speed train.By analyzing the operation status and potential safety hazards of non-crossing type overhead crossing for No.18 turnout during the operation test of Yinchuan-Zhongwei section of Yinchuan-Lanzhou passenger dedicated line,the paper puts forward optimized measures,which are able to guide the parameter adjustment of non-crossing type overhead crossing for No.18 turnout on the line under construction and operation.
