Description
Technical field
The utility model is related to jack-up unit design and mounting technique field, specifically a kind of jack up in ocean engineering
Platform pile shoe water filling device.
Background technology
At present, during jack-up unit design and installation, the water filling form of shoe without related national standard and
Professional standard, each shipyard is designed and builds according to respective custom, and some shipyards do not consider the convenience of operation,
The security of operation.Existing water filling device need to be transferred to shoe in platform pitching pile operation front opening device upper cover plate, spud leg
The water surface is completely immersed in, shoe packs up spud leg after filling water, and after operating personnel reach maintenance platform closing cover plate, spud leg issues beginning
Pitching pile operation, the operating time is long.In for self-elevating drilling platform pitching pile operation process, particularly in the operation area that stormy waves is big
Domain, personal security, the activity duration is even more important.Accordingly, it would be desirable to one kind can shorten the pitching pile time, personnel safety is can guarantee that again
Shoe water filling device.
Utility model content
To solve the above problems, the utility model provides a kind of jack-up unit shoe water filling device, can shorten pitching pile
Activity duration, can realize again unattended, it is ensured that personnel safety.
The technical solution adopted in the utility model is：A kind of jack-up unit shoe water filling device, is fixed on by flange
In shoe, the device includes casing, the first screen pack, second screen pack of upper lower open mouth, floats ball and spring, the top of the casing
Portion is provided with the first screen pack, and the bottom of casing is provided with the second screen pack, and one end of the spring is fixed on the second screen pack, bullet
The other end of spring is fixed with ball float, and limiting plate is provided with above the ball float, and the limiting plate is provided with through hole, the through hole position
In ball float surface and the diameter of the diameter less than ball float of through hole, the top of the limiting plate is the first screen pack.
Less than the through hole internal diameter of flange, the bottom of the casing is fixed on shoe manhole to the external diameter of the casing by flange
Place.The beneficial effects of the utility model are：1st, the common material that simple, involved use part is commonly used using shipyard is made
It is made；2nd, in jack-up unit spud leg decentralization process, the present apparatus, to shoe automatic water filling, shortens pitching pile operation by hydraulic pressure
Time, 3, realize unattended, security performance is high, can be widely applied to the manufacture of shoe water filling device.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model opening；
Fig. 2 is the structural representation of the utility model closed mode；
Wherein, the 1, first screen pack, 2, limiting plate, 3, ball float, 4, spring, 5, casing, the 6, second screen pack, 7, flange,
8th, bolt, 9, through hole, 10, shoe.
Specific embodiment
In order to deepen to understanding of the present utility model, make into one to of the present utility model below in conjunction with embodiment and accompanying drawing
Step is described in detail, and the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.
As illustrated in fig. 1 and 2, a kind of jack-up unit shoe water filling device, is fixed in shoe 10 by flange 7, the dress
The casing 5 including upper lower open mouth, the first screen pack 1, the second screen pack 6, ball float 3 and spring 4 are put, the top of casing 5 is provided with
One screen pack 1, the bottom of casing 5 is provided with the second screen pack 6, and one end of spring 4 is fixed on the second screen pack 6, spring 4 it is another
One end is fixed with ball float 3, and the top of ball float 3 is provided with limiting plate 2, and limiting plate 2 is provided with through hole 9, and through hole 9 is just gone up positioned at ball float 3
Less than the diameter of ball float, to floating position-limiting action on ball float, the top of limiting plate 2 is first to limiting plate 2 to the diameter of side and through hole
Screen pack 1.
Less than the through hole internal diameter of flange 7, the bottom of casing 5 is fixed on the manhole of shoe 10 by flange 7 to the external diameter of casing 5
Place.
Operation principle：Ball float is moved up and down according to hydraulic pressure inside and outside shoe in casing under water；Spring to ball float provide to
On active force, treat that the device reaches certain depth with being put into water under shoe, when hydraulic pressure reaches Opening pressure, ball float is toward moving down
Dynamic, the device is opened, and after water is filled in shoe, ball float acts on float downward in spring force, and the device is closed.
The fabrication and installation process of the device is as follows：1）Welded in advance in workshop and complete the body structure that coaming plate is constituted, casing
It is the integral frame structure of the device, can is steel pipe, it is also possible to rolled with steel plate；The external diameter of casing 5 is less than in the through hole of flange 7
Footpath；2）Weld 6 pairs of devices of the second screen pack and play second filtration, spring 4, ball float 3, welded limiting plate 2 are installed；3）Weldering
Connect the first screen pack 1；4）Casing 5 is positioned in shoe 10 at manhole, bolt 8 is fixed into the device through the through hole of flange,
Bolt and nut is tightened, is installed.
Need first to open cover plate for manhole in traditional approach, decentralization shoe lifts shoe to after filling water, then to operating in shoe
Manhole cover is closed at platform, then starts pitching pile operation, and the present apparatus can when certain depth is transferred in shoe automatic water filling, section
The operating time has been saved, unattended, safe, the especially big operating area of stormy waves has been capable of achieving it, it is to avoid the sea is rough
The potential danger for causing.
