After leveling device 100 is mounted on drilling platform 9, by being transferred after integral hoisting to pier position, leveling work is just proceeded by.Leveling
In the process, bearing 11 and distribution beam 3 are fixed with spiral by tightening the first nut 6 and third nut 8 first, simultaneously
The second nut 7 is unclamped to unclamp bearing beam 21 and spiral.Top lifting jack, supporting pile 2 move downward under pressure, when
2 bottom end bearing capacity of supporting pile is more than drilling platform 9 after the gravity of 100 location point of drilling platform self-regulated leveling device, and supporting pile 2 is not
It moves still further below, jack 7 continues top lifting, and casing 1 will drive distribution beam 3 to move upwardly together at this time, and it is high to have reached adjustment
The purpose of degree.So as to drilling platform 9 be made accurate in place on the sea without any reference object using the present invention and risen and fallen
Sea bed face establish smooth job platform.
The present invention also provides a kind of method using above-mentioned 100 leveling drilling platform 9 of drilling platform self-regulated leveling device, the party
Method includes the following steps：
S1：Multiple drilling platform self-regulated leveling devices 100 are installed on drilling platform 9；
To reduce over-water construction process, 100 all structures of drilling platform self-regulated leveling device in factory process and are installed just
Position.After drilling platform 9 completes, the quantity of drilling platform self-regulated leveling device 100 is arranged as required to, it is shown in Figure 4, this
4 sets of drilling platform self-regulated leveling devices 100 are mounted on drilling platform 9 altogether in invention.Steel pipe is used with conventional borehole platform
The mode of driven pile combination bracing is compared, easy for installation, reduces Potential Working Time For Operation At Sea, improves construction efficiency.
S2：9 integral hoisting of drilling platform of drilling platform self-regulated leveling device 100 will be installed, transferred after transporting to pier position；
According to 9 gravity of drilling platform, size, suitable crane barge equipment is selected to carry out integral hoisting, band after transporting to pier position
The whole decentralization of drilling platform self-regulated leveling device 100.Drilling platform 9 is cast anchor alignment system before transferring using crane barge equipment itself institute band
It is positioned, adjusts and integrally transferred in the range of its plan-position to positioning accuracy, 1 base opening meeting of casing under the effect of gravity after implantation
It is inserted into the certain depth of sea bed.According to the soft or hard degree of sea bed, casing 1 is inserted into sea bed depth and also will appear deviation, causes drilling flat
The basic quadrangle height difference of platform 9 differs, and need to carry out follow-up leveling construction.
S3：After drilling platform 9 is transferred, drilling platform 9 is measured in each 100 position of installation drilling platform self-regulated leveling device
Highly, the difference in height of each two position, and design height difference adjusting range are calculated；

The connection of bearing beam 21 and connector 4 is unclamped, adjustment regulating mechanism 5 makes its elongation, supporting pile 2 is driven to move downward, until bearing
2 bottom end bearing capacities of stake are more than drilling platform 9 after the gravity of 100 location point of drilling platform self-regulated leveling device, continue elongation and adjust
Mechanism 5 moves upwards casing 1；
Connector 4 in the present invention is spiral, and spiral runs through bearing 11, bearing beam 21 and distribution beam 3, bearing
11st, bearing beam 21 and distribution beam 3 respectively by the first nut 6, the second nut 7 and third nut 8 removably with the screw-thread steel
Muscle is fixed.Bearing 11 and distribution beam 3 with spiral are fixed by tightening the first nut 6 and third nut 8, pass through release
Second nut 7 unclamps bearing beam 21 and spiral.In addition, the regulating mechanism 5 in the present invention is jack, top lifting jack,
Supporting pile 2 moves downward under pressure, when 2 bottom end bearing capacity of supporting pile is more than drilling platform 9 in drilling platform self-level(l)ing
After the gravity of 100 location point of device, supporting pile 2 no longer moves downward, and jack 7 continues top lifting, and casing 1 will drive point at this time
It is moved upwardly together with beam 3, has achieved the purpose that adjust height.
S5：Step S4 is repeated, until the difference in height of any two position after difference in height adjusting range, fixes bearing beam
21 with connector 4.
Tighten the second nut 7 to fix bearing beam 21 with spiral, jack oil return, then 9 weight of drilling platform convert to
Supporting pile 2 is born, and removes distribution beam 3 and jack, continues subsequent construction.
