Synchronous deviation rectifying method for double-lifting-point hydraulic hoist
The invention provides a double-lifting-point hydraulic hoist synchronous deviation rectifying method which comprises the steps that the working pressure of hydraulic cylinders is obtained through pressure sensors, the working positions of piston rods of the hydraulic cylinders are obtained through hydraulic cylinder stroke sensors, working pressure balance serves as the gate stable operation standard, and the deviation of the working pressure and the position deviation of the hydraulic cylinders on the two sides are obtained. As a control signal for synchronous deviation correction, opening change of a proportional speed regulating valve is controlled, flow change of working pressure oil entering and exiting from hydraulic cylinders on two sides is adjusted, working speed change of the hydraulic cylinders is realized, and the effect of stabilizing a gate is achieved; in the gate operation process, according to the working pressure deviation, a reference change strategy of stroke deviation control deviation correction is set, and the influence of installation deviation in the process is better adapted; the setting of the control value of the deviation rectifying operation can be adjusted on site according to the actual situation of on-site debugging, and the on-site actual operation condition can be quickly responded.
本发明提供一种双吊点液压启闭机同步纠偏方法，包括：采用压力传感器获取液压缸工作压力，采用液压缸行程传感器获得液压缸活塞杆的工作位置，以工作压力平衡为闸门平稳运行基准，通过获两侧液压缸的工作压力偏差和位置偏差，作为同步纠偏的控制信号，控制比例调速阀的开度变化，调整两侧液压缸进出工作压力油的流量变化，实现液压缸的工作速度变化，达到闸门平稳的效果；在闸门运行过程中，根据工作工作压力偏差，设置行程偏差控制纠偏的基准变更策略，更加适应过程中的安装偏差的影响；纠偏操作的控制值的设置，可根据现场调试的实际情况现场调整，可快速响应现场的实际运行条件。
