The invention relates to hydraulic rescue hoisting equipment for a CRH (China Railway High-speed) train, substantive improvement and breakthrough are conducted on the prior art, the requirement that rerailing is conducted at different heights from the bottom face of a bogie side frame of each CRH train series to the rail face can be met, the one-time accurate rerailing is achieved, tedious repeated hoisting operation is avoided,the hoisting operation is stable and reliable, and the safety is good; quickness, accuracy and short rescue time are realized; in the resetting process of the CRH train, when a load is transferred, a displacement compensation device on a transverse moving trolley compensates the curvilinear motion of the CRH train to be moved, the optimal stability is ensured, the cylinder body is not inclined, and the tedious and time-consuming positioning operation that a certain included angle needs to be formed between a transverse moving beam and the relative position of asteel rail in the transverse moving beam laying and mounting process is omitted.
本发明是动车组液压救援起复设备,对现有技术进行实质性改进和突破,能够实现各动车组系列的转向架侧架底面距轨面不同高度进行复轨的需要,一次性准确复轨,避免了繁琐的重复起升作业、起复作业平稳可靠、安全性好,快速准确、救援时间短;在动车复位过程中,当负载转移时,横移小车上的位移补偿装置补偿了要移动的动车的曲线运动,确保最佳稳定性而又不使缸体倾斜,节省了繁琐且耗时的横移梁铺设安装时须与钢轨相对位置呈一定夹角的定位作业。
