The invention provides a lifting stand column for a contact network operation vehicle and a power integration platform of the lifting stand column, and relates to the technical field of contact network operation, the lifting stand column comprises an outer shell, a bottom plate is fixed to the bottom of the outer shell, a first supporting rod and a second supporting rod are movably installed on the top of the bottom plate, and a first connecting rod is rotationally connected to the top of the first supporting rod. According to the device, a hydraulic telescopic rod is controlled to be shortened, a first connecting rod and a second connecting rod are pulled close to the middle, the included angle between a first supporting rod and a second supporting rod is decreased, the tops of the first supporting rod and the second supporting rod rise, and the first connecting rod and the second connecting rod are driven to rise; meanwhile, the included angle between the third supporting rod and the fourth supporting rod is also decreased, the top plate is driven to move towards the top, the first supporting rod and the second supporting rod as well as the third supporting rod and the fourth supporting rod move at the same time to increase the rising height, and therefore the telescopic rate of the lifting stand column is increased; and the working platform can be lifted to a higher position, and the stability is better.
本发明提供一种接触网作业车用升降立柱及其动力集成平台,涉及接触网作业技术领域,包括外壳体,所述外壳体底部固定有底板,所述底板顶部活动安装有第一支撑杆和第二支撑杆,所述第一支撑杆顶部转动连接有第一连接杆。本装置通过控制液压伸缩杆缩短,将第一连接杆和第二连接杆向中部拉近,第一支撑杆和第二支撑杆之间的夹角变小,第一支撑杆和第二支撑杆顶部升高,带动第一连接杆和第二连接杆升高,同时第三支撑杆和第四支撑杆之间的夹角也变小,带动顶板向顶部移动,第一支撑杆和第二支撑杆、第三支撑杆和第四支撑杆同时移动增加上升的高度,从而达到提高升降立柱的伸缩率,作业平台可以升高到较高位置同时稳定性更好的效果。
