The specific embodiment
Below in conjunction with accompanying drawing a kind of hydraulic rapid pipe-dismounting device for sludge delivery pipe of dredger structure of the present invention is described in detail.
A kind of hydraulic rapid pipe-dismounting device for sludge delivery pipe of dredger specific works principle of the present invention is:
When the second 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 by contacting with oil cylinder locking arm guiding 10.When the first 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.Locking spring 14 in the first fuel supply chamber 3 plays two protective effects in the situation that oil pressure decline in the first fuel supply chamber 3 still can provide coupling mechanism force.
As shown in Figure 1, 2, a kind of hydraulic rapid pipe-dismounting device for sludge delivery pipe of dredger of the present invention, it comprises takes off pipe apparatus main body 1 fast, be equipped with and hull hard tube adpting flange 13 in described pipe apparatus main body 1 back of taking off fast, in the described pipe apparatus main body middle part of taking off fast three hydraulic pressure execution oil cylinders 2 are installed, each hydraulic pressure is carried out on the oil cylinder respectively the first fuel supply chamber 3 and the second fuel supply chamber 4, is provided with locking spring 14 in fuel supply chamber 3.Be firm banking 11 and take off fast pipe apparatus main body 1 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, at oil cylinder telescopic arm 15 and oil cylinder locking arm 6 junctions torsionspring 5 is installed.Be oil cylinder locking arm guiding 10 in described oil cylinder locking arm 6 bottoms, in described oil cylinder locking arm 10 bottoms of leading O-ring seal 9 arranged, contact with O-ring seal 9 and be flexible pipe adpting flange 12.Be respectively equipped with locking boss 7 and locking groove 8 in the place that described flexible pipe adpting flange 12 contacts with oil cylinder locking arm 6.
Under normal condition, the first fuel supply chamber 3 on the hydraulic pressure execution oil cylinder 2 and the oil in the second fuel supply chamber 4 are in packing state, closely cooperate by the locking concave station 7 on the hydraulic locking arm 6 and the locking groove 8 on the flexible pipe adpting flange, make 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 second 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 larger or other emergency, the second fuel supply chamber 4 fuel feeding, 15 elongations of oil cylinder telescopic arm, oil cylinder locking arm 6 bottoms are by contacting with oil cylinder locking arm guiding 10, 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, the first fuel supply chamber 3 fuel feeding, oil cylinder telescopic arm 15 shortens, 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 is as shown in Figure 3 carried out cylinder control system and is comprised fuel tank 25, end for oil screen 24 links to each other with fuel tank 25, link to each other with hydraulic oil pump 22 at the described other end for oil screen, be connected with power set motor 23 at described hydraulic oil pump, connect successively the oil inlet end of overflow valve 21, one way valve 20 in described hydraulic oil pump outlet, 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 bidirectional hydraulic control one way valve 17 and two one-way throttle valves 16 successively, connects respectively the first fuel supply chamber 3 and second fuel supply chamber 4 of three hydraulic pressure execution oil cylinders 2 in the outlet of described bidirectional 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 enters pipeline, by overflow valve 21 regulation of hydraulic system is arrived operating pressure, and force value can directly read from pressure indicator 19.Hydraulic oil enters the first fuel supply chamber 3 or the second fuel supply chamber 4 that hydraulic pressure is carried out oil cylinder 2 by the effect of solenoid operated directional valve 18, bidirectional 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.
