The specific embodiment
Below in conjunction with accompanying drawing the dredge boat slurry pipeline hydraulic pressure of the utility model being taken off the pipe unit structure fast specifies.
The dredge boat slurry pipeline hydraulic pressure of the utility model takes off the concrete operating principle of pipe unit fast:
When fuel supply chamber 4 fuel feeding, 15 elongations of oil cylinder telescopic arm, oil cylinder locking arm 6 links to each other with oil cylinder telescopic arm 15, and the oil cylinder locking arm is separated from oil cylinder locking arm 6 and flexible pipe adpting flange 12 through contacting with oil cylinder locking arm guiding 10.When fuel supply chamber 3 fuel feeding; Oil cylinder telescopic arm 15 shortens; Oil cylinder locking arm 6 leaves the oil cylinder locking arm guiding 10 that hydraulic pressure is carried out oil cylinder 2, and the locking boss 7 on the oil cylinder locking arm 6 cooperates with locking groove 8 on the flexible pipe adpting flange 12, and flexible pipe adpting flange 12 is locked.Under locking spring 14 in the fuel supply chamber 3 situation that oil pressure descends in fuel supply chamber 3, still coupling mechanism force can be provided, play two protective effects.
Like Fig. 1, shown in 2; A kind of dredge boat slurry pipeline hydraulic pressure of the utility model takes off pipe unit fast; It comprises takes off pipe unit main body 1 fast, is equipped with and hull hard tube adpting flange 13 in described pipe unit main body 1 back of taking off fast, in the described pipe unit body midsection position of taking off fast three hydraulic pressure execution oil cylinders 2 is installed; Each hydraulic pressure is carried out has fuel supply chamber 3 and fuel supply chamber 4 respectively on the oil cylinder, in fuel supply chamber 3, be provided with locking spring 14.Be firm banking 11 and take off pipe unit main body 1 fast and fix in described hydraulic pressure execution oil cylinder 2 bottoms.Carrying out oil cylinder 2 front ends at described hydraulic pressure has oil cylinder telescopic arm 15 and oil cylinder locking arm 6, in oil cylinder telescopic arm 15 and oil cylinder locking arm 6 junctions torsionspring 5 is installed.Is oil cylinder locking arm guiding 10 in described oil cylinder locking arm 6 bottoms, O-ring seal 9 is arranged, contact with O-ring seal 9 and be flexible pipe adpting flange 12 in described oil cylinder locking arm 10 bottoms of leading.Be respectively equipped with locking boss 7 and locking groove 8 in the place that said flexible pipe adpting flange 12 contacts with oil cylinder locking arm 6.
Under normal condition; Fuel supply chamber 3 on the hydraulic pressure execution oil cylinder 2 is in packing state with the oil in the fuel supply chamber 4; Locking groove 8 through on locking concave station on the hydraulic locking arm 67 and the flexible pipe adpting flange closely cooperates, and makes as a whole with 12 one-tenth of flexible pipe adpting flanges with hull hard tube adpting flange 13.Hydraulic pressure is carried out in the fuel supply chamber 4 on the oil cylinder 2 and is provided with locking spring 14, even leak also still can locking cylinder locking arm 6 for the oil in the oil pocket, plays the two protective effects of safety.
When stormy waves during bigger or other emergency; Fuel supply chamber 4 fuel feeding; 15 elongations of oil cylinder telescopic arm; Oil cylinder locking arm 6 bottoms are through contacting with oil cylinder locking arm guiding 10, and the locking boss 7 on the oil cylinder locking arm 6 is separated from the locking boss 8 on the flexible pipe adpting flange 12, and oil cylinder locking arm 6 and flexible pipe adpting flange 12 are separated from.Whole flexible pipe partly breaks away from the safety of whole ship of safeguard protection with hull.
When flexible pipe adpting flange 12 is connected with hull hard tube adpting flange 13; At first flexible pipe adpting flange 12 is aimed at the O-ring seal 9 on the hull hard tube adpting flange 13; Fuel supply chamber 3 fuel feeding; Oil cylinder telescopic arm 15 shortens, and oil cylinder locking arm 6 leaves oil cylinder locking arm guiding 10, and the locking boss 7 on the oil cylinder locking arm 6 is locked with the locking boss 8 on the flexible pipe adpting flange 12.
Hydraulic pressure as shown in Figure 3 is carried out cylinder control system and is comprised fuel tank 25; One end of fuel feeding filter 24 links to each other with fuel tank 25; The other end at described fuel feeding filter links to each other with hydraulic oil pump 22; On described hydraulic oil pump, be connected with power set motor 23, export the oil inlet end that connects overflow valve 21, one way valve 20 successively at described hydraulic oil pump, the other end of described overflow valve 21 links to each other with fuel tank.In the outlet of one way valve 20 and the entrance of solenoid operated directional valve 18 pressure indicator 19 is installed; Outlet at described solenoid operated directional valve 18 is connected to two-way hydraulic control one-way valve 17 and two one-way throttle valves 16 successively, connects the fuel supply chamber 3 and fuel supply chamber 4 of three hydraulic pressure execution oil cylinders 2 respectively in the outlet of described two-way hydraulic control one-way valve 17.
In described hydraulic jack executive system, be motor 23 power supplies, drive hydraulic oil pump 22 and rotate, hydraulic oil gets into pipeline, through overflow valve 21 regulation of hydraulic system is arrived operating pressure, and force value can directly read from pressure indicator 19.Hydraulic oil gets into fuel supply chamber 3 or the fuel supply chamber 4 that hydraulic pressure is carried out oil cylinder 2 through the effect of solenoid operated directional valve 18, two-way hydraulic control one-way valve 17 and one-way throttle valve 16, hydraulic pressure execution oil cylinder is moved back and forth reach the purpose of required control.
