The invention discloses a turnover type hydraulic supporting device, and relates to a supporting device used when a highway-railway dual-purpose engineering vehicle carries out construction operationon a railway track. The device comprises a base and a support arranged under the base, wherein one side of the end of the support is rotationally connected with the base, and the other side of the endof the support is movably connected with the base through a bolt assembly. The base comprises a cross beam assembly, a bottom plate and a rotating shaft. The cross beam assembly comprises an upper cover plate, a web plate and a lower cover plate which form a box-shaped structure; the support comprises an oil cylinder, a rotating inserting plate and a movable inserting plate, wherein the rotatinginserting plate and the rotating vertical plate are connected through a rotating shaft. The beneficial effects are that the hydraulic supporting base can rotate around the rotating shaft in the longitudinal direction of the vehicle body, the requirement that the vehicle body is supported when the vehicle operates on a railway track is met, and meanwhile, damage to line equipment or accidents caused by abnormal stretching of the support oil cylinder when the vehicle runs on the track is avoided, and the approach angle and departure angle of the vehicle during road running are increased.
一种翻转式液压支撑装置,涉及一种公铁两用工程车在铁路轨道上施工作业时的支撑装置。它包括底座和设于底座下部的支撑,支撑端部一侧与底座转动连接,另一侧通过插销组件与底座活动连接;所述底座包括横梁组件、底板、和转轴,横梁组件包括上盖板、腹板、下盖板,三者形成箱型结构;所述支撑包括油缸、转动插板和活动插板,转动插板和转动立板通过转轴连接。本发明具有的有益效果是:液压支撑座可绕转轴在车体纵向方向上转动,满足车辆在铁路轨道上作业支撑车体的同时,避免车辆在轨道上行驶时支撑油缸异常伸出造成损毁线路设备或发生事故,并加大车辆在公路行驶时的接近角、离去角。
