Emergency operation hydraulic system and hydraulic hoist
The invention discloses an emergency operation hydraulic system and a hydraulic hoist. The disclosed emergency operation hydraulic system comprises dual-directional flow regulation electric control valves in one-to-one correspondence to multiple hydraulic power elements, a hydraulic pump, multiple stroke detection sensors for detecting strokes of the hydraulic power elements, and a synchronous controller. An oil discharge outlet of the hydraulic pump communicates with first oil ports of the dual-directional flow regulation electric control valves; second oil ports of the dual-directional flowregulation electric control valves are connected with first pipe joints for communicating with corresponding hydraulic power element hydraulic chambers; the multiple stroke detection sensors are in signal connection with a signal input end of the synchronous controller; and a signal output end of the synchronous controller is in signal connection with the electronic control ends of the dual-directional flow regulation electric control valves, and the through-flow rates of the dual-directional flow regulation electric control valves are controlled with a reserved strategy according to detectionsignals of the stroke detection sensors, so that the hydraulic power elements act synchronously. The emergency operation hydraulic system can meet the requirement on opening or closing a large-scalegate with multiple hydraulic actuating elements while keeping lower cost at the same time.
本发明公开一种应急操作液压系统和液压启闭机。公开的应急操作液压系统包括与多个液压动力元件一一对应的双向流量调节电控阀、液压泵、用于检测液压动力元件行程的多个行程检测传感器和同步控制器；液压泵的排油口与双向流量调节电控阀的第一油口相通；双向流量调节电控阀的第二油口连接用于连通对应液压动力元件液压腔的第一管接头；多个行程检测传感器分别与同步控制器的信号输入端信号相连；同步控制器的信号输出端分别与双向流量调节电控阀电控端信号相连，并根据行程检测传感器的检测信号以预定策略控制双向流量调节电控阀通流流量，使各液压动力元件同步动作。该应急操作液压系统可以在保持较低成本的同时，满足开启或关闭具有多个液压执行元件的大型闸门的需要。
