The utility model aims to provide a telescopic steel rail lead wire fixing support for a ballastless track bed, and belongs to the technical field of railway signal equipment installation. Comprising an upper fixing device fixed on a ballastless track bed track plate, a lower fixing device fixed on a roadbed cement ground, and a telescopic lead wire fixing device connected with the upper fixing device and the lower fixing device. The ballastless track bed can solve the problems that the height from the top surface of a ballastless track bed track plate to the ground is variable and the variation range is large due to winding and small curve radius of part of high-speed rails. 本实用新型的目的在于提供一种无砟道床用可伸缩钢轨引接线固定支架，属于铁路信号设备安装的技术领域，包括固定在无砟道床轨道板上的上部固定装置、固定在路基水泥地面上的下部固定装置以及连接上部固定装置和下部固定装置的可伸缩的引接线固定装置，本实用新型通过调节支架长短，可解决因部分高铁线路蜿蜒曲折、曲线半径小使得无砟道床轨道板顶面距离地面的高度多变且变化范围大的问题。
