It following is a brief introduction of the disassembly principle of hydraulic bolt jacking system provided in an embodiment of the present invention:
After hydraulic bolt jacking system completes platform lift work, it can will determine the latch assembly on ring beam 56 and all insert
Enter in the pin hole 1a of spud leg 1, the load of self-elevating ocean platform is allowed directly to pass to spud leg 1 by determining ring beam 5；At this point, solid
Pile frame 3, rotating ring beam 4 and lift cylinder 2 are not subject to load, then can dismantle wedge bracket 3 and the main deck surface a of hull, will
The first half wedge bracket connecting plate 301a and the second half wedge bracket connecting plate 301b are dismantled, and the first half wedge bracket 3a and the second half are consolidated
After pile frame 3b is removed, by the first half rotating ring beam pin shaft 402a and the first half rotating ring beam axis pin base 402b and the second half rotating ring beams
Pin shaft 403a and the second half rotating ring beam axis pin base 403b are dismantled respectively, by the first half rotating ring beam connecting plate 401a and the second half rotating rings
Beam connecting plate 401b is dismantled, so that the first half rotating ring beam 4a and the second half rotating ring beam 4b be dismantled, and then realizes hydraulic bolt
The disassembly of jacking system.
The latch assembly determined on ring beam is entirely insertable spud leg by hydraulic bolt jacking system provided in an embodiment of the present invention
In pin hole, the load of self-elevating ocean platform is made directly to pass to spud leg by determining ring beam, at this point, wedge bracket, rotating ring beam and
Lift cylinder is not subject to load, then can dismantle the main deck surface of wedge bracket and hull, and the first half on wedge bracket are consolidated
Pile frame connecting plate and the second half wedge bracket connecting plates are dismantled, after the first half wedge brackets and the second half wedge brackets are removed, by rotating ring
The first half rotating ring beam pin shafts on beam and the first half rotating ring beam axis pin bases are dismantled, by the second half rotating ring beam pin shafts and the second half rotating rings
Beam axis pin base is dismantled, and the first half rotating ring beam connecting plates and the second half rotating ring beam connecting plates are dismantled, thus by the first half rotating ring beams
It dismantles, rotating ring beam is all removed, after the wedge bracket and rotating ring beam disassembled can re-assembly, only with the second half rotating ring beams
Need to reconfigure one determine ring beam can be down to applying on other self-elevating ocean platforms, this greatly reduces jack up
The cost of ocean platform, meanwhile, hydraulic bolt jacking system can pass through the first half rotating ring beam connecting plates and the second half rotating ring beams
Connecting plate improves the anti-shear ability of the first half rotating ring beams and the second half rotating ring beams, moreover, determining multiple latch assemblies on ring beam
It is entirely insertable in the pin hole of spud leg, so that the self-elevating ocean platform is able to maintain existing working condition, does not influence to rise certainly
The normal work of formula ocean platform.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
