Wherein
Described upper and lower expansion bellows hydraulic servo clamping device is made up of upper and lower bellows jig and upper and lower jig hydraulic servo transmission mechanism;
Described upper and lower expansion bellows hydraulic servo clamping device is that the center is provided with the expansion bellows that vertically is coaxial docking;
Described upper and lower bellows jig is respectively part two symmetries, that be connected half figure of eight shape that standard shape on the upper and lower jig hydraulic servo transmission mechanism, inside cross-section and folded bellows coincide;
Described upper and lower bellows jig is fixed with the piston of its hydraulic servo transmission mechanism respectively;
The hydraulic cylinder of described upper and lower bellows jig hydraulic servo transmission mechanism and piston are installed in respectively on interior horizontally disposed upper shifting board of described appliance stand and the base plate.The hydraulic cylinder of described upper and lower bellows jig hydraulic servo transmission mechanism is connected with hydraulic pump by hydraulic line.
Described gap hydraulic servo governor motion is formed tube grip mechanism guide pillar and gap hydraulic pressure servotab structure by two;
Described two tube grip mechanism guide pillar fixedlyed connected with described upper shifting board respectively, be used for keeping to produce moving of vertical direction tube grip mechanism and base plate;
The oil cylinder of described gap hydraulic servo governor motion is fixed on described frame bottom, its piston mobile the connection with described.
Described expansion bellows vertically is equipped with on the appliance stand to pipe unit and is used to rotate mobile castor.Described expansion bellows vertically supports upper and lower expansion bellows hydraulic servo clamping device and gap hydraulic servo governor motion to the appliance stand of pipe unit.
Described expansion bellows vertically is equipped with the appliance stand of pipe unit bottom and is used to rotate mobile castor (5-1).
Bellows jig of the present utility model can be changed the jig of different size as required.The bellows jig that different size bellows welding adopts specification therewith to match.Can increase clamping frictional force like this, effectively clamp bellows, nor as for make the distortion of ripple pipe clamp because of chucking power is excessive.The oil cylinder of hydraulic gear can adapt to the clamping needs of bellows.
Two guide pillars of gap of the present utility model hydraulic servo governor motion are used for keeping gap hydraulic servo governor motion and base plate can only produce moving of vertical direction.Piston rod by this hydraulic servo governor motion moves, and regulates the groove gap of two bellowss.
Be installed in the little opinion below the appliance stand, can make the expansion bellows vertically pipe unit be moved and rotates relative to the bellows of squeezing into the down-hole, thereby guarantee two pipe centerings.
A kind of expansion bellows of the utility model realizes that at the rig floor platform expansion bellows is to pipe vertically to pipe unit.
(1) adopt hydraulic drive, easy and simple to handle.
(2) safety, reliable.
(3) change bellows clamping device anchor clamps, can satisfy Φ 215.9mm, Φ 241.3mm and three kinds of specification bellowss of Φ 311.15mm to the pipe needs.
(4) two ligament sizes are adjustable continuously up and down, can flexible adaptation different tube diameters and welding process requirement.
(5) regulate the axiality of two pipes up and down automatically, ensure two pipes with one heart.
(6) counterpart precision height, efficient height can follow-up welding quality of efficient raising and efficient.
