摘　　要：铁路信号技术及设备更新换代迅速,道岔转辙机作为信号系统重要组成部分,对保障铁路安全运行起到通道及桥梁的作用。铁路车站信号改造复联试验及联锁换装是一项专业性极强、对既有运行设备影响很大的工程。既有铁路信号改造是施工难点,特别是停点前未能完成调试的施工内容,极易造成行车事故。结合实际信号改造工程,论述道岔改造复联试验和过渡施工技术,通过前期充分准备、编制施工方案,科学准确地开展施工与测试,保证信号设备试验彻底,从而确保线路正点开通和行车安全。The technology and equipment of railway signaling are experiencing rapid growth. As an important part of the signaling system, the switch machine plays a role as a channel and bridge in ensuring the safe operation of railways. The signaling renovation and recovery test and interlocking upgrade at stations are highly specialized, which has a great impact on the existing operation equipment. The signaling renovation of existing railways is difficult in terms of construction, particularly the construction content failed to be completed in debugging before the maintenance window ends, which may probably cause train operation accidents. In combination with the actual signaling renovation works, the recovery test and transition construction technology of turnout reconstruction are discussed. Based on the adequate preparation and formulation of the construction scheme in the early stage, the construction and test can be carried out scientifically and accurately to ensure the thorough test of signaling equipment, thus ensuring the on-time opening of the railway and train operation safety.
