A three-position four-way electro-hydraulic reversing valve and a hydraulic control check valve enter the rodless cavity of the filter lifting cylinder to realize a compression action of the machine head. At this time, the system pressure is the setting value of the first remote control overflow valve , when the pressure of the second electric contact reaches the upper limit control pressure, the right end of the first three-position four-way electro-hydraulic reversing valve and the left end of the third three-position four-way electro-hydraulic reversing valve are de-energized, and the system is controlled by the hydraulic control check valve. Hold pressure.

After the pressure reaches a certain value, the piston rod moves back to drive the machine head to complete the loose open action. After the machine head is released, the one-way variable hydraulic pump completes the action of pulling and removing the board through the chain drive. When the left end of the second three-position four-way electro-hydraulic reversing valve is energized, the pressure oil of the one-way variable hydraulic pump enters the oil inlet port of the left end of the two-way quantitative hydraulic motor, and the two-way quantitative hydraulic motor rotates to complete the board removal action through the chain; when the second three When the right end of the four-way electro-hydraulic reversing valve is energized, the action of pulling the plate is completed. At this time, the right end of the third three-position four-way electro-hydraulic reversing valve is energized, and the pressure of the system is the setting value of the second remote control overflow valve. The present invention is controlled by an electric contact pressure gauge to realize automatic oil supply and pressure maintenance of the system, with long pressure maintenance time and high pressure stability. The invention also controls the opening degree of the one-way throttle valve connected in series on the oil circuit by regulating the liquid control one-way valve, which can avoid the impact of the hydraulic system caused by the excessive pressure release caused by the improper movement speed of the internal control piston of the hydraulic control one-way valve vibration and noise. It not only meets the pressure relief requirements of the system, but also ensures that the return stroke of the piston controlled by the hydraulic control check valve is not affected.

When the pressure expression of the first electric contact reaches the upper limit control pressure, the first three positions The right end of the four-way electro-hydraulic directional valve is de-energized, and the system maintains pressure; when the pressure drops to the lower limit control pressure, the right end of the first three-position four-way electro-hydraulic directional valve is energized again, and the one-way variable hydraulic pump supplies pressure to the filter lifting cylinder. Fill the rod chamber with oil, so that the pressure in the rodless chamber rises, and the system starts to maintain pressure again. When the left end of the first three-position four-way electro-hydraulic directional valve is energized to switch the first three-position four-way electro-hydraulic directional valve to the left position, the pressure oil of the one-way variable hydraulic pump passes through the first three-position four-way electro-hydraulic directional valve It enters the rod cavity of the filter lifting cylinder, and at the same time reversely guides the hydraulic control check valve through the one-way throttle valve to realize the pressure relief of the rodless cavity of the hydraulic cylinder.
