Description
Technical field
A kind of hoisting machinery field is the utility model is related to, more particularly to a kind of jack-up unit reversible shoe.
Background technology
To ensure jack-up unit trouble free service, the shoe of platform must is fulfilled for bearing capacity, resistant slide in working sea area
Ability, resistance to capsizing and boots ability is pulled out, the form and loaded area and sea bed geology of shoe are closely related.Sea bed geology is general
Than relatively soft, and platform involves great expense, and generally increases platform in the fixed form shoe of spud leg bottom installation large area
Support force, ensure the safety and stability that platform is stood, to ensure existence energy of the platform under normal operation and storm environment
Power.Fix generally circular in cross section shoe profile, rectangle or polygon.During pile pulling, shoe is bigger, shoe with bottom silt
Frictional force is bigger, and the pile pulling time is longer, higher to platform buoyancy requirement, and pile pulling difficulty also accordingly increases.Fixed shoe can not
The geology change of different waters is adapted to, causes platform to be restricted with operating area because of the change of geology.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, reduction shoe pile extraction resistance, shortens and pull out
Stake time, the reversible shoe for jack-up unit for improving the safety and stability that jack-up unit is stood.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of jack-up unit reversible shoe,
Its innovative point is：Including shoe body and switching mechanism；
The shoe body includes spud leg and installed in spud leg lower end otic placode；
The switching mechanism includes the hinge and shoe blade being symmetricly set on otic placode, and the shoe blade passes through hinge
Axle is hinged on otic placode.
Further, the shoe blade includes big blade and vanelets.
Further, in addition to it is arranged on the intermediate beam of spud leg bottom, the shoe blade is along the symmetrical cloth in intermediate beam both sides
Put, and one end of shoe blade is extended to above intermediate beam, the big blade is arranged on centre, and the vanelets are arranged on two
Side.
Further, the hinge is arranged symmetrically in shoe bottom, the centre position of any one in the hinge of both sides
Big blade is hinged, the end positions of another hinge are hinged vanelets, and the one end for the shoe blade being hinged on the hinge of side
Extend to the lower section of symmetrical side hinge.
The utility model has the advantage of：
（1）Shoe blade completes switching process by gravity and buoyancy, simple in construction, reduction shoe pile extraction resistance, shortens
The pile pulling time, improve the safety and stability that jack-up unit is stood.
（2）Shoe blade is divided into big blade and vanelets, facilitates big blade to be arranged on centre, and vanelets are arranged on both sides,
Convenient preferably fixed spud leg.
（3）Using the shoe blade being arranged symmetrically on hinge, shoe blade can rely on gravity and buoyancy to complete upset,
Play limited support using intermediate beam, it is convenient, flexible.
（4）The shoe blade being hinged on the hinge of side, play limited support using the hinge of opposite side, without
Increase extra limited support part.
Brief description of the drawings
Fig. 1 is a kind of front view of the embodiment one of jack-up unit reversible shoe of the utility model.
Fig. 2 is a kind of top view of embodiment one of jack-up unit reversible shoe of the utility model.
Fig. 3 is a kind of front view of embodiment two of jack-up unit reversible shoe of the utility model.
Fig. 4 is a kind of top view of embodiment two of jack-up unit reversible shoe of the utility model.
Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model discloses a kind of jack-up unit reversible shoe, including
Spud leg 1, shoe blade, otic placode 2 and hinge 3 etc. may be reversed.Hinge 3 hangs on the both sides of spud leg 1, pile pulling and pitching pile through otic placode 2
When, shoe blade may be reversed and overturn around hinge 3；Shoe blade includes big blade 6 and vanelets 7.
Embodiment one
As shown in Figure 1 and Figure 2, the first scheme, the big width of blade 6 are the diameter of spud leg 1, and the width of vanelets 7 is inserted according to platform
Stake requires selection.Arrangement is that big blade 6 is arranged on centre, and both sides are vanelets 7, and shoe blade is along 4 symmetrical cloth of intermediate beam
Put, and one end of shoe blade is extended to above intermediate beam, intermediate beam 4 can support the front end of shoe blade, to shoe blade
Upset carries out spacing and support.
During the pitching pile of scheme one, buoyancy suffered by shoe blade afterbody is more than gravity, and shoe blade is around hanging on otic placode two
The hinge 3 of side is symmetrically overturn to the direction of intermediate beam 4, and shoe vane nose applies pressure to intermediate beam 4, and shoe is inserted pre- in sea bed
When positioning is put, pressure is maximum.During pile pulling, shoe blade afterbody is larger by earthing pressure, and shoe blade turns over to vertical direction
Turn, pile pulling power constantly reduces.When sea bed is extracted in shoe, buoyancy suffered by blade afterbody is more than gravity, and vane nose is to intermediate beam side
To symmetrical upset, recover horizontality.When sea is extracted in shoe, gravity suffered by blade is more than buoyancy, and blade is overturn to vertical shape
State.
Embodiment two
As shown in Figure 3, Figure 4, second scheme, it is not necessary to which the support of intermediate beam 4, shoe blade are overturn to water around hinge 3
During level state, other end hinge 3, which can limit shoe blade, to be continued to overturn.Big blade 6 is opposite with the reverses direction of vanelets 7.Great Ye
The width of piece 6 is the diameter of spud leg 1, and the width of vanelets 7 requires to select according to platform pitching pile.Arrangement is during big blade 6 is arranged on
Between, both sides are vanelets 7；And the one end for the shoe blade being hinged on the hinge of side extends to the lower section of symmetrical side hinge.
During the pitching pile of scheme two, buoyancy suffered by shoe blade afterbody is more than gravity, and both sides vanelets 7 can be inverse around hinge 3
Hour hands are rotated and contacted with hinge 3, and blade 6 broad in the middle is rotated clockwise around hinge 3 and contacted with hinge 3, size shoe blade
Symmetrical upset, shoe form maximum surface area, and the stress of hinge 3 is maximum.During pile pulling, earthing pressure suffered by shoe blade afterbody
Larger, both sides rotate clockwise compared with vanelets around hinge 3, and blade 6 broad in the middle rotates counterclockwise around hinge 3, and pile pulling power constantly subtracts
It is small.When sea bed is extracted in shoe, buoyancy suffered by blade is more than gravity, and blade is symmetrically overturn around hinge 3, recovers horizontality.Shoe
When extracting sea, gravity suffered by blade is more than buoyancy, and blade is overturn to vertical state.
General principle and principal character of the present utility model has been shown and described above.The technical staff of the industry should
Solution, the utility model are not restricted to the described embodiments, and simply illustrate that this practicality is new described in above-described embodiment and specification
The principle of type, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various changes and modifications,
These changes and improvements are both fallen within claimed the scope of the utility model.The utility model requires protection scope is by appended
Claims and its equivalent thereof.
