Dynamic, lifter rack 10 is engaged with lifter wheel 12 so that and lifter wheel 12 can do ascending motion compared with lifter rack 10, due to
Lifter wheel 12 is mounted on wedge bracket ring beam 6 so that lifter wheel 12 can drive wedge bracket ring beam 6 to do ascending motion until the
One piston rod 9c extend out to range.Meanwhile when hydraulic oil promotes piston to be moved to the first rod chamber direction, second piston
Bar 9d retracts, and so as to which the second ring beam 3 be driven to move up, state as shown in Figure 4 is realized, when second piston bar 9d is retracted to minimum
During stroke, the second ring beam latch assembly 5 on the second ring beam 3 is inserted into the pin hole of spud leg b, by the first ring beam 2
One ring beam latch assembly 4 is extracted in the pin hole by spud leg b, and starts drive component, and two drive components is made to respectively drive two
A drive gear 11 rotates, and lifter rack 10 is made to do ascending motion, during lifter rack 10 rises, positioned at power rack
The lifter wheel 12 in 8 left sides rotates clockwise, and the lifter wheel 12 positioned at the right side of power rack 8 rotates counterclockwise, at this point, the
During two piston rod 9d stretch out, and First piston bar 9c retracts, power rack 8 is motionless compared with spud leg b standings, and due to
Lifter wheel 12 is integrally fixed on wedge bracket ring beam 6 so that lifter wheel 12 can drive wedge bracket ring beam 6 to rise, and solid stake
The distance that mounting ring beam 6 rises can be a pitch.And so on, self-elevating ocean platform a is by drive gear 11 and lifting
Gear 12 is constantly creeped on lifter rack 10 and power rack 8 back and forth, and rising realization is continuous to be risen.
Hydraulic bolt lifting gear provided in an embodiment of the present invention, by the pin hole of the first ring beam latch assembly insertion spud leg
Interior, the First piston bar of support cylinder is in the minimum stroke state retracted, and hydraulic oil, hydraulic oil are passed through into the second rod chamber
Piston is promoted to be moved to the first rod chamber direction so that First piston bar is stretched out, and First piston bar stretching can drive power rack
It moves up together, the lifter wheel engaged with power rack rotates, and the lifter wheel on the left of power rack rotates counterclockwise, position
Lifter wheel on the right side of power rack rotates clockwise, and lifter rack is engaged with lifter wheel so that lifter wheel can be opposite
Ascending motion is done in lifter rack, since lifter wheel is mounted on wedge bracket ring beam so that lifter wheel can drive wedge bracket
Ring beam does ascending motion until First piston bar extend out to range.Meanwhile piston is promoted to the first rod chamber in hydraulic oil
When direction is moved, second piston bar is retracted, so as to which the second ring beam be driven to move up, when second piston bar is retracted to minimum stroke
When, by the pin hole of the second ring beam latch assembly insertion spud leg on the second ring beam, the first ring beam on the first ring beam is inserted
Pin assemblies start drive component by being extracted in the pin hole of spud leg, and two drive components is made to respectively drive two drive gears
It rotates, lifter rack is made to do ascending motion, during lifter rack rises, the lifter wheel on the left of power rack is suitable
Hour hands rotate, and the lifter wheel on the right side of power rack rotates counterclockwise, at this point, stretched out in second piston bar, and first lives
During stopper rod is retracted, power rack is motionless compared with spud leg standing, and since lifter wheel is integrally fixed at wedge bracket ring beam
On so that lifter wheel can drive wedge bracket ring beam to rise, and the distance that wedge bracket ring beam rises can be a pitch.Such as
This is reciprocal, and self-elevating ocean platform constantly swashes row by drive gear and lifter wheel in lifter rack and power rack back and forth
Rise and realize continuous rising, moreover, the hydraulic bolt lifting gear can realize the locking of self-elevating ocean platform, also have anti-
The characteristics of answering quick, safety and large carrying capacity.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
