Embodiment Construction
[0021] Such as figure 1 As shown, the automatic oil replenishment type isomorphic double-cylinder leveling system includes active cylinder 1, controller 2, proportional solenoid valve 3, passive cylinder 4, redundant inclination sensor 5, and redundant inclination sensor 5 is installed on the working platform of the aerial work vehicle. On the platform, the inclination angle of the working platform of the aerial work vehicle is detected in real time; the oil cylinder installed between the turntable and the boom is called the active cylinder 1, the oil cylinder installed between the boom and the working platform is called the passive cylinder 4, and the controller 2 , proportional solenoid valve 3 are installed on the turntable.
[0022] The active cylinder 1 and the passive cylinder 4 of the leveling system have the same structural size. The rodless cavity and the rod cavity of the two cylinders are connected respectively, and balance valves are respectively provided on the pa...
