市域铁路道岔转辙机设置问题探讨

Discussion about the setting of suburban railway switch machine

分析了市域铁路道岔转辙机设置常见问题,在充分研究12号可动心道岔转辙机特点基础上,为满足转辙机安装空间要求,提出在有越行线(停车线)的车站取消越行线(停车线)反向行车端的安全线方案,或采取多线段道岔错开布置方案;在转辙机与桥梁电缆沟冲突地段提出采用强电电缆支架通过,弱电电缆槽增加宽度降低高度从转辙机下方通过的方案,或采用加宽转辙机安装区域桥面宽度的方案。

It analyzed common problems about setting of suburban railway switch machine.Based on the characteristics of switch machine,and in order to meet the space requirements of switch machine,this article puts forward the viewpoint that cancel the safety line at the reverse end of the crossing line(stop line),or turnout staggered arrangement in the multi-line.In the conflict between the point machine and the bridge cable trench,it is proposed to use the strong electric cable bracket to pass,increase the width and lower the height of the weak electric cable groove to pass under the switch machine,or use the widened width of the bridge floor.
