A novel steel wheel crawler-type highway-railway dual-purpose chassis mainly comprises a telescopic crawler-type chassis, a steel wheel device and a rotary platform. Connecting frames on the two sides of the telescopic crawler-type chassis can adjust the distance between the left crawler belt and the right crawler belt through telescopic oil cylinders, and the requirement that the whole machine walks in a ballastless track bed surface layer pit and the surface of a ballastless track plate and a ballast track bed is met. Steel wheel devices with power are arranged in front of and behind the working platform and are suitable for walking under the rail working condition after steel rails are laid; and by controlling the lifting oil cylinder of the steel wheel device, the steel wheel can fall off the rail and be suspended, so that the highway-railway dual-purpose running state is switched. A cab, a hydraulic system, an electrical system and different rail construction working devices can be carried on the working platform of the steel wheel crawler-type highway-railway dual-purpose chassis, and the steel wheel crawler-type highway-railway dual-purpose chassis has important significance on safe, efficient and convenient rail line construction and line operation overhaul and maintenance.

    一种新型钢轮履带式公铁两用底盘,主要包括:可伸缩履带式底盘、钢轮装置、回转平台。可伸缩履带式底盘两侧的连接架可通过伸缩油缸以调整左右履带的间距,满足整机在无砟线路基床表层坑内和无砟轨道板、有砟线路道床表面行走的需求;工作平台前后装有带动力的钢轮装置,适用于钢轨铺设完成后有轨工况下行走;通过控制钢轮装置的升降油缸,实现钢轮的落轨和悬空,从而切换公铁两用行驶状态。钢轮履带式公铁两用底盘的工作平台上可搭载司机室、液压系统、电气系统和不同的轨道建设施工工作装置,对安全、高效、便捷地进行轨道线路建设施工和线路运营检修维护有着重要意义。
