3011 do not connect with active rodless cavity hydraulic fluid port 3012.Another part passes through the first oil inlet of the proportional reversing valve 3024 again,
Flowed out to from the first oil-out of the proportional reversing valve 3024 in the rodless cavity of the active hydraulic jack 301, be the master
The rodless cavity of hydraulic cylinder 301 is oil-filled, and the active piston bar 3013 of the active hydraulic jack 301 is moved downward, so that band
Move the hook 60 to move downward, to compensate the hook 60 because wave acts on the rising displacement produced.Also, when the active
When piston rod 3013 is moved downward, the hydraulic oil in the rod chamber of the active hydraulic jack 301 is forced out, the hydraulic pressure being forced out
Oil is flowed into after the second one-way conduction valve 3029 from the first oil inlet of the proportional reversing valve 3024, and then from institute
The first oil-out for stating proportional reversing valve 3024 is flowed out in the rodless cavity of the active hydraulic jack 301, thinks the active
The rodless cavity supplement hydraulic oil of hydraulic jack 301, because the hydraulic oil that the rod chamber of the active hydraulic oil flows out is directly height
Hydraulic fluid is pressed oil, and therefore, it can with the hydraulic oil that the rod chamber of the active hydraulic oil flows out is the active hydraulic jack 301
Rodless cavity supplement section hydraulic oil, can so reduce the oil pump 70 needs for the rod chamber of the active hydraulic jack 301
The high pressure liquid force feed of offer, that is, reduce the workload of oil pump 70, effectively saved the energy.
4th, the active piston bar 3013 is moved upwards under the control of described control unit 10, so as to drive described big
Hook 60 is moved upwards.
When described control unit 10, which detects the hook 60, to be moved downward, the 9th fuel feeding control of described control unit 10
End processed exports corresponding control signal to the control signal input of the solenoid directional control valve 3025, and its first oil-feeding control end
Corresponding control signal to the first control signal input of the proportional reversing valve 3024, the first of the oil pump 70 is exported to go out
The high pressure liquid force feed of hydraulic fluid port outflow, after the 5th pressure adjustment relief valve 3021 and the 5th filter 3022, a part of high pressure
Second oil inlet and oil-out of the hydraulic oil Jing Guo the solenoid directional control valve 3025 flow to first logic core 3026 and described
The control port of second logic core 3027 so that the first hydraulic fluid port of first logic core 3026 and the second hydraulic fluid port cut-off, it is described
First hydraulic fluid port of the second logic core 3027 and the second hydraulic fluid port cut-off, i.e., the active rod chamber hydraulic fluid port of described active hydraulic jack 301
3011 do not connect with active rodless cavity hydraulic fluid port 3012.Another part high pressure liquid force feed is again by the of the proportional reversing valve 3024
One oil inlet, flows out, and then pass through the first one-way conduction valve 3028 from the second oil-out of the proportional reversing valve 3024
It is that the rod chamber of the active hydraulic jack 301 is oil-filled in the rod chamber for flowing to the active hydraulic jack 301 afterwards, the master
The active piston bar 3013 of hydraulic cylinder 301 is moved upwards, so that the hook 60 motion upwards is driven, it is described big to compensate
Hook 60 acts on the sinking displacement produced because of wave, also, when the active piston bar 3013 is moved upwards, the active hydraulic pressure
Hydraulic oil in the rodless cavity of oil cylinder 301 is forced out, and the hydraulic oil being forced out is fuel-displaced from the first of the proportional reversing valve 3024
Mouth is flowed into, and then is flowed out from the second oil inlet of the proportional reversing valve 3024, is flowed back to after the 6th filter 3023
