Detailed description of the invention
A kind of adjustable-angle hydraulic-driven bench board as depicted in figs. 1 and 2, comprises base 1, hydraulic actuating cylinder 4 and Hydraulic Pump 9, and described Hydraulic Pump 9 is unidirectional quantitative hydraulic pump.Strut bar 2 is installed with on the upside of described base 1 one end, hinged with described hydraulic actuating cylinder 4 cylinder base on the upside of described base 1 other end, described strut bar 2 end and described hydraulic actuating cylinder 4 knock-pin end respectively with platen 3 two ends on the downside of hinged, on the downside of described platen 3, angular transducer 10 is installed, the rodless cavity of described hydraulic actuating cylinder 4 is communicated with the A mouth of three-position four-way electromagnetic directional valve 5, the rod chamber of described hydraulic actuating cylinder 4 is communicated with the B mouth of three-position four-way electromagnetic directional valve 5, the P mouth of described three-position four-way electromagnetic directional valve 5 is communicated with fuel tank, the O mouth of described three-position four-way electromagnetic directional valve 5 and described check valve 8 outlet, described Hydraulic Pump 9 exports and be provided with by pass valve 7 between fuel tank, bi-bit bi-pass solenoid directional control valve 6 is provided with between described by pass valve 7 hydraulic control head piece and fuel tank.
The working process of adjustable-angle hydraulic-driven bench board of the present invention is: first this adjustable-angle hydraulic-driven bench board is arranged on control position, when the left position access of three-position four-way electromagnetic directional valve 5, hydraulic actuating cylinder 4 rodless cavity pressure is greater than its rod chamber pressure, piston upwards, hydraulic actuating cylinder 4 knock-pin slowly promotes platen 3 and rotates clockwise around strut bar 2 end, when platen 3 inclination angle reaches desirable value, angular transducer 10 sends the upper access of signal control bi-bit bi-pass solenoid directional control valve 6, by pass valve 7 starts off-load, now check valve 8 is closed automatically, platen 3 inclination angle and lockable.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solution of the present invention.
