For a swelled counterpart method in the hydraulic pressure of pipeline butt axiality and circularity, for guaranteeing that two are carried out the axiality of counterpart pipeline and the circularity of counterpart end face, adopt swelled counterpart device in hydraulic pressure to carry out counterpart, its step is as follows:
One, front tension mechanism is entered to tensioner after first pipeline,
1), when hydraulic oil enters cylinder barrel by oil circuit 1, by piston 4 and main shaft, be fixed together, so cylinder barrel travels forward under the pressure-acting of hydraulic oil, several activity building blocks 2.1 that make to be evenly distributed on same circumference travel forward simultaneously, and the building block 2.1 of activity simultaneously radially produces displacement along main shaft 4;
2), when piston 4 contact with the cylinder barrel bottom of motion, cylinder barrel 2.3 stop motions, circumference and internal diameter of the pipeline that now several activity building block 2.1 upper surfaces form coincide; In this process, the hydraulic oil in cylinder barrel 2.3 returns to fuel tank by oil circuit 2;
3), when hydraulic oil enters cylinder barrel by oil circuit 2, be fixed on piston on main shaft motionless, so cylinder barrel is motion backward under the pressure-acting of hydraulic oil, make to be evenly distributed on N the building block motion backward simultaneously on same circumference, building block simultaneously radially produces displacement along axle;
4), when piston movement is to cylinder barrel when bottom, piston stop motion, now several activity building blocks 2.1 are got back to initial position under the effect of spring 2.2 pulling force; In this process, in cylinder barrel, hydraulic oil returns to fuel tank by oil circuit 1;
Two, second pipeline put into rear tension mechanism tensioner, the building block of rear tension mechanism and the building block of front tension mechanism are in full accord again, and the job step of rear tension mechanism is identical with front tension mechanism job step;
1), when hydraulic oil enters cylinder barrel by oil circuit 1, after building block tensioner, can make equally second pipeline coaxial with main shaft 4; Rigidity and intensity that now first device for cleaning pipeline crossed main shaft 4 keep coaxial with 7 second pipelines 8.
2), described working connection is the deep hole on main shaft 4, replaced circumscribed oil pipe, saved to a great extent the space of equipment, and improved the reliability of oil circuit;
This is comprised of front tension mechanism, rear tension mechanism, brass mechanism, main shaft, guiding mechanism, hoisting mechanism, support, hydraulic system and pneumatic system etc. mouthpart chief component parts,
Illustrate: major function is to guarantee two to carry out the axiality of counterpart pipeline and the circularity of counterpart end face
1, former tension mechanism is example explanation (rear tension mechanism is identical with front tension mechanism principle):
Front tension mechanism mainly contains two cover swelling device compositions, and its version is identical.
When hydraulic oil enters cylinder barrel by oil circuit 1, because piston and main shaft are fixed together, so cylinder barrel travels forward under the effect of pressure, N the building block that makes to be evenly distributed on same circumference travels forward simultaneously, and building block simultaneously radially produces displacement along axle.When piston movement arrives cylinder barrel bottom, piston stop motion, now circumference and the internal diameter of the pipeline of N building block upper surface composition coincide.In this process, in former cylinder barrel, hydraulic oil returns to fuel tank by oil circuit 2.When hydraulic oil enters cylinder barrel by oil circuit 2, because piston and main shaft are fixed together, so cylinder barrel motion backward under the effect of pressure makes to be evenly distributed on N the building block motion backward simultaneously on same circumference, while building block radially produces displacement along axle.When piston movement arrives cylinder barrel bottom, piston stop motion, now N building block got back to initial position under the effect of spring tension.In this process, in former cylinder barrel, hydraulic oil returns to fuel tank by oil circuit 1.
2, front tension mechanism enters tensioner after first pipeline, is assembled into device and is synchronized with the movement due to two, and the external diameter of the circle that forms of two groups of building block upper surfaces is identical, so just effectively guaranteed the axiality of first pipeline and main shaft; Again second pipeline put into rear tension mechanism tensioner.Rear tension mechanism operation principle is identical with front tension mechanism operation principle, and the building block of building block and front tension mechanism is in full accord.After tensioner, equally effectively guaranteed the axiality of second pipeline and main shaft.Now the axiality of first pipeline and second pipeline just can be guaranteed by the good rigidity of main shaft and intensity.
3, working connection is the deep hole on main shaft, has replaced circumscribed oil pipe in the past, has saved to a great extent the space of equipment, and has effectively raised the reliability of oil circuit.
