高寒地区既有线液压道岔过渡方案研究

Research on Existing Line Hydraulic Turnout Transition Scheme in Alpine Areas

近年来从我国铁路发展的现状来看,投资保持高水平,新建、改造铁路工程不断增多。既有线铁路信号设备也随着不断的改造升级,铁路运输能力有了新的突破。在既有线铁路信号系统的升级改造过程中,处于我国高寒地区铁路道岔转换设备老化、维护不方便等问题也日益显著,面对各种各样的挑战,结合既有道岔展开调查研究。根据道岔的动作程序、工作原理,制定详细的作业流程、选用最优方案、绘制最准确的过渡图纸来指导施工。文章就上述内容展开讨论。

In recent years,based on the current situation of railway development in China,the investment maintains a high level,and the number of new and renovated railway projects has been increasing.With the continuous transformation and upgrading of the existing railway signal equipment,there has been a new breakthrough in the railway transportation capacity.In the process of upgrading and transforming the existing railway signal system,the problems of aging and inconvenient maintenance of railway turnout conversion equipment in China’s alpine areas become increasingly significant.For various challenges,the investigation and research are performed in combination with existing turnouts.According to the action procedure and working principle of the turnout,a detailed operation process is formulated,the optimal plan is selected,and the most accurate transition drawings are plotted to guide the construction.This paper discusses the above content.
