桑梓店站信号过渡处理方案研究

Study on Signal Transition Processing Scheme of Sangzidian Station

以邯济铁路桑梓店站增二线及车站改造为例,提出衔接牵出线道岔拆除后的特殊处理方案,过渡期间在防护信号机点灯条件中插入道岔表示条件,从而保证进路安全;针对插入道岔的位置及启用时机的不同,分别提出切实可行的道岔过渡处理方式,满足车站运输需要;探讨过渡期间无岔区段插入道岔表示处理方式,提出合理的过渡方案,顺利完成车站信号过渡。通过对车站改造过程中信号过渡方案的总结研究,为以后改造车站过渡设计提供工程参考。

Based on the double-line reconstruction project of Sangzidian railway station on Handan-Jinan railway,this paper proposes a special processing scheme for connecting turnout of switching lead when this turnout has been removed.In order to ensure safety of railway traffic during the signal transition,switch normal indication of transition turnout is inserted into the lighting circuit of protection signal.According to the diff erent position and enable timing of inserting turnout,practical treatment methods of transition turnout control circuit are proposed separately,so as to meet the needs of railway transportation.The processing method of inserting turnouts in the switchless section during the transition period is discussed,and a reasonable transition plan is proposed to successfully complete the station signal transition.Through the summary of the signal transition scheme in the process of station transformation,these suggestions presented in this paper can supply references for transition scheme for station reconstruction project in the future.
