The working principle of apparatus of the present invention is:
When marine riser carries out lowering operation, claw driving hydraulic cylinder 7 is synchronous first is retracted, and claw 8 is bounced back, water proof is formed
Pipe transfers channel, as shown in Fig. 1 (b).Hook will be lowered marine riser and sling and be transported at chuck hub top, later slowly
Decline, when marine riser upper flanges disk lower end surface will be aligned with 8 top surface of claw, hook stops.Claw driving hydraulic cylinder 7 is same
Step is stretched out, and six claws 8 are stretched out, and marine riser supporting surface is formed, as shown in Fig. 1 (a).It is hydraulic after claw 8 reaches predetermined position
7 stop motion of cylinder, and lock, claw 8 is fixed on current location.Hereafter hook continues lowering risers, until marine riser is complete
It is supported entirely by claw 8.After the completion of the movement, hook decontrols manned marine riser, slings next marine riser to chuck hub
Top slowly declines, after next marine riser lower flange is contacted with marine riser upper flange in place, by quick coupling by two
The connection of root marine riser.Hook is slightly upwardly promoted later, and marine riser of the seat on claw 8 is lifted, and keeps claw 8 unloaded.Claw drives
Hydrodynamic cylinder pressure 7 releases locking, synchronous to retract, and a claw 8 is withdrawn, and forms marine riser again and transfers channel.Hook is transferred later
Marine riser, when that will be aligned to next marine riser upper flanges disk lower end surface with 8 top surface of claw, hook stops, in repetition
Step is stated, until marine riser has all connect, reaches target length.
When marine riser carries out reclaimer operation, work flow is opposite with marine riser decentralization.Hook is slightly upwardly promoted first, makes card
Pawl 8 is unloaded, synchronous retract of rear claw driving hydraulic cylinder 7 claw 8 is withdrawn, form marine riser and above mention channel, Fig. 1 (b).Hook
Water proof tubing string is continued to lift up, when the marine riser of top is completely under 8 top of claw and next marine riser upper flanges disk
After end face is aligned with 8 top surface of claw, hook stops.Synchronous stretch out of claw driving hydraulic cylinder 7 ejects claw 8, forms marine riser
Supporting surface such as Fig. 1 (a).After claw 8 reaches predetermined position, hydraulic cylinder stop motion is simultaneously locked, and claw 8 is fixed on present bit
