Specific embodiment
Below in conjunction with the accompanying drawings with enforcement row, this utility model is described in further detail.
As illustrated, this utility model vehicular road surface implement elevator cylinder control device, this device unidirectional
Flow speed control valve（One-way throttle valve）1 and bi-bit bi-pass electrically-controlled valve 2 be arranged on valve block, one-way speed-regulating valve 1 and bi-bit bi-pass electrically-controlled valve 2
Between pipeline relation be in parallel, parallel pipeline is connected between the P mouth of valve block and A mouth.One-way speed-regulating valve 1 is only from A mouth to P mouth list
To conducting.The A mouth of valve block connects the rod chamber of oil cylinder 8, and the P mouth of valve block connects the hydraulic fluid port 3 of three position four-way directional control valve by oil pipe.Oil cylinder
Rodless cavity connect the hydraulic fluid port 4 of three position four-way directional control valve by oil pipe.Hydraulic pump 7 flowline connects the hydraulic fluid port of three position four-way directional control valve
5, the hydraulic fluid port 6 of three position four-way directional control valve accesses fuel tank.
As shown in figure 1, this utility model vehicular road surface implement elevator cylinder control device, its work process is such as
Under：
1st, road surface implement is lifted by hydraulic jack：
Solenoid 1DK energising on three position four-way directional control valve, 2DK power-off, now four on three-position four-way valve hydraulic fluid port
3rd, in relation such as Fig. 1 between 4,5 and 6, the left part of three position four-way directional control valve is illustrated, and hydraulic fluid port 5 and hydraulic fluid port 3 communicate, hydraulic fluid port 6 He
Hydraulic fluid port 4 communicates.Solenoid 3DK power-off in bi-bit bi-pass electrically-controlled valve, bi-bit bi-pass electrically-controlled valve 2 is opened, hydraulic pump output
Hydraulic oil flows to hydraulic fluid port 3 from the hydraulic fluid port 5 of three position four-way directional control valve, enters the P mouth of valve block, flows to valve through bi-bit bi-pass electrically-controlled valve 2
The A mouth of block, to cylinder rod chamber, oil cylinder piston moves up, and is lifted road surface implement by cylinder piston rod.Oil cylinder is no
The hydraulic oil of rod cavity enters the hydraulic fluid port 4 of three position four-way directional control valve, flows back to fuel tank after flowing to hydraulic fluid port 6.
2nd, device is slowly steadily put down by hydraulic jack：
Solenoid 2DK energising on three position four-way directional control valve, 1DK power-off, now four on three position four-way directional control valve
