the electro-hydraulic system drives a low-power-consumption gear pump to work through a direct-current motor, the low-power-consumption gear pump outputs oil at high pressure to hydraulic oil, the pressure is adjusted through a pressure adjusting valve, the flow rate of the high-pressure oil is adjusted through a speed adjusting valve, then the high-pressure oil is input into a rodless cavity of an oil cylinder through an electromagnetic directional valve, and a piston of the oil cylinder is pushed to move, so that the position of an actuating cylinder is controlled through the output of oil cylinder force, a movable rod plug of the actuating cylinder moves outwards until a mechanical locking position, and the working state is achieved;
if the actuating cylinder does not retract after retracting to a certain position, which may be caused by insufficient load, the pressure relief valve below the manual emergency pump can be opened, and the actuating cylinder can return to the initial position;
the wireless remote controller starting button rotates to a closing position, the motor oil pump set stops working, then the power switch is turned off, the quick connector connected with the oil pipe and the oil cylinder is pulled down, and the wireless remote controller and the oil pipe are put back into the vehicle body;
in the using process, if a lithium power battery in the electric system is dead or the electric quantity is too low, the electric hydraulic system cannot be started, a manual emergency pump can be used, a manual emergency pump inserted rod beside a remote controller box is taken out, the manual emergency pump is inserted, the engine skin can be slowly lifted up and down, the pressure release valve is required to be closed before the manual emergency pump is pressed, the pressure release valve can be slowly rotated when the skin is required to be lowered, the skin can slowly fall down, and the pressure release valve is required to be closed after the manual emergency pump is used up;
the emergency stop button is a main power switch of the electric control system and is also an emergency stop button in an emergency state, and the emergency stop button is required to be pressed when the vehicle is not used.
