The invention relates to the technical field of tower crane jacking hydraulic system control, in particular to an electric control multi-way reversing valve for a tower crane jacking hydraulic system, which comprises a valve body, a valve rod, a spring, a spring seat, an electromagnet assembly, a throttling screw, a shunting screw and a safety overflow valve assembly. Installation operation can be achieved by two persons, safety operation risks can be reduced, labor intensity of workers is reduced, working efficiency is improved, specifically, a three-position six-way reversing valve structure is adopted, the pressure and flow fine adjustment performance is achieved, hydraulic impact is small, oil ways are connected in series, when valve rods are in the middle position, oil inlets and outlets are completely closed, and the pressure maintaining effect is achieved; the throttling screw and the flow dividing screw are installed in the valve body, the movement speed of oil cylinders with different cylinder diameters can be controlled, a hydraulic system is controlled through a PLC program, one-key operation can be achieved in tower crane jacking operation, the safety risk is reduced, the labor cost is saved, and the working efficiency is improved.

    本发明涉及塔机顶升液压系统控制技术领域,具体为一种用于塔机顶升液压系统的电控多路换向阀,包括阀体、阀杆、弹簧、弹簧座、电磁铁组件、节流螺钉、分流螺钉和安全溢流阀组件,通过上述电控多路换向阀的应用以及PLC程序控制,安装作业可实现为2人操作,可降低安全作业风险,减小工人劳动强度,提高工作效率,具体为,采用三位六通换向阀结构具有压力、流量微调性能,液压冲击小,各油路之间采用串联方式,各阀杆在中位时,进出油口完全封闭,具有保压作用,阀体内装有节流螺钉和分流螺钉,可控制不同缸径的油缸的运动速度,液压系统通过PLC程序控制,塔机顶升作业可实现一键操作,降低安全风险、节省人工成本、提高工作效率。
