The invention discloses a lifting control system for hydraulic rescue of a maglev vehicle, which comprises an oil tank and a hydraulic cylinder for driving a rescue wheel to lift, a pressure supply system for discharging oil is arranged in the oil tank, and the output end of the pressure supply system is connected with the hydraulic cylinder by arranging an oil path control system. An oil return system used for connecting an oil tank with return oil is arranged on a connecting pipeline of the oil way control system and the hydraulic cylinder, the oil way control system comprises a three-position four-way electromagnetic valve, a first balance valve and a second balance valve, and the three-position four-way electromagnetic valve comprises an oil port A1, an oil port A2, an oil port A3 and an oil port A4. According to the invention, continuous lifting control of the vehicle before and after rescue can be realized, a certain degree of adverse effect of huge impact load of the vehicle body on the vehicle in the descending process of the vehicle is avoided, and the movement stability of the vehicle and the rescue control system in the rescue and rescue canceling processes is realized.
本发明公开了一种磁悬浮车辆的液压救援用升降控制系统,包括油箱和用于驱动救援轮升降的液压缸,所述油箱的内部设置有用于出油的压力供给系统,所述压力供给系统的输出端通过设置油路控制系统与液压缸连接,所述油路控制系统与液压缸的连接管路上设置有用于油箱连接回油的回油系统,所述油路控制系统包括有三位四通电磁阀、第一平衡阀和第二平衡阀,所述三位四通电磁阀包括有油口A1、油口A2、油口A3和油口A4。本发明可实现车辆在救援前后车辆升降连续控制,避免了车辆下降过程中车体的巨大冲击载荷对车辆产生一定程度的不良影响,实现了车辆和救援控制系统在救援和取消救援过程中运动平稳性。
