The invention relates to the technical field of aviation support equipment related manufacturing, in particular to an aircraft electric hydraulic synchronous control jack which comprises a triangular support, an actuator cylinder assembly is fixed to the middle of the triangular support, the actuator cylinder assembly stretches out and draws back to achieve jacking and landing of an aircraft, at least three jack sets need to be used for jacking the aircraft, and the jack sets are fixed to the triangular support. One group of jacks are used for jacking the fuselage, the other two groups of jacks are used for jacking the two groups of wings, an electric control box is further mounted on the triangular frame, and in the jacking process, synchronous starting of the pre-jacked actuator cylinder assemblies in the multiple groups of jacks is achieved through a synchronous jacking button arranged on the electric control box. An actuator cylinder assembly in one jack making contact with a machine body can operate at a fixed speed, the actuator cylinder assemblies in the other two jacks keep the height difference before operation, and the speed of the actuator cylinder assemblies is adjusted through a PID control system arranged in an electric control box to follow the jack with the fixed speed.
本发明涉及航空保障设备相关制造技术领域,具体是指一种飞机电动液压同步控制千斤顶,包括三角架,所述三角架中部固定有作动筒组件,所述作动筒组件进行伸缩动作,实现飞机的顶升和降落,飞机顶升需要使用到至少三组千金顶,一组对机身进行顶升,另外两组对两组机翼进行顶升,所述三角架上还安装有电气控制箱,顶升过程中,通过电气控制箱上设置的同步顶升按钮实现多组千斤顶中完成预顶的作动筒组件的同步启动,其中一台与机身接触的千斤顶中的作动筒组件会固定速度运行,另外两台千斤顶中的作动筒组件保持运行前的高度差,通过电气控制箱内置的PID控制系统调整自身速度追随固定速度千斤顶。
