The invention relates to a rail transit rolling stock lifting jack which comprises a movable supporting assembly, a guide sliding plate and a transverse driving assembly. The movable supporting assembly comprises a movable support and a floating supporting wheel assembly, the floating supporting wheel assembly is movably connected with the movable support, and the movable support abuts against theguide sliding plate and is positioned, or the movable support is separated from the guide sliding plate and is driven by the transverse driving assembly to move along the guide sliding plate under supporting of the floating supporting wheel assembly. The lifting jack has the beneficial effects that when the movable supporting assembly deviates from the vehicle supporting position, the movable supporting assembly is moved to meet the requirement for the vehicle supporting position, the lifting jack is more suitable for the requirement for complex working conditions of an overhauling site, andthe overhauling efficiency is improved. And the movable support is in direct contact with the guide sliding plate under the pressure of the vehicle body, the supporting surface is large, and the structural strength and reliability are high.
本发明涉及一种轨道交通机车车辆架车机,包括活动支撑组件、导向滑板和横向驱动组件,活动支撑组件包括活动支架和浮动支撑轮组件,浮动支撑轮组件可运动地连接于活动支架上,活动支架与导向滑板抵接并定位,或者活动支架与导向滑板分离,并在横向驱动组件的驱动下在浮动支撑轮组件的支撑下沿导向滑板移动。本发明的有益效果是:活动支撑组件与车辆支撑位有偏差时,移动活动支撑组件满足车辆支撑位置的要求,架车机更加适合检修现场复杂工况的需求,提高了检修效率。受到车体的压力后,活动支架与导向滑板直接接触,支撑面大、结构强度高、可靠性高。
