Description
Technical field
The present invention relates to a kind of efficient controllable type jack-up unit shoe device, belong to ocean engineering auxiliary equipment field.
Background technology
Along with the increasing of the development and utilization of marine resources, the scale of the development of modern stake power leg formula ocean platform is increasing, large quantities of ocean platforms (especially large-scale self-elevating ocean platform) is applied to the development of resources of the deep water sea area such as the East Sea and the South Sea gradually, circle or the polygon card form of shoe in the past are still continued to use in shoe due to a lot of jack-up unit, when platform leg is installed, driving depth is more shallow, mobility is not strong, and often can there is ground shakiness, spud leg sedimentation is uneven, platform inclination, wash away the phenomenon with naughty sky, thus cause platform structure unstable, and then have influence on the structural safety of ocean platform.Therefore, exploitation one effectively can be carried out pitching pile, fast stability, be fixed, and the novel controllable type platform pile shoe device of pile pulling can be able to be facilitated again after offshore mining work completes just to seem extremely important, is a urgent problem at present.
Summary of the invention
The object of this invention is to provide a kind of efficient controllable type jack-up unit shoe device.
The problem to be solved in the present invention is that self-elevating ocean platform can pitching pile in the silt ground of various seabeds and install fixed platform work, can overcome well again different waters ground condition ocean platform stake power leg is caused stability, floading condition adverse effect, can complete relief jack-up unit in resource exploitation work again can easily pile pulling and movement.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of efficient controllable type jack-up unit shoe device, comprise boot of elevator, spud leg jacket casing, fluid pressure type locking torsion bar, built-in rotatable blades and ultrasonic probe, it is characterized in that: in described spud leg jacket casing, be provided with fluid pressure type locking torsion bar, fluid pressure type locking torsion bar is connected with built-in rotatable blades, built-in rotatable blades is arranged in boot of elevator, boot of elevator is arranged on below spud leg jacket casing, and boot of elevator top is provided with ultrasonic probe.
Described built-in rotatable blades is made up of multi-disc fanning strip.
Described boot of elevator is circular configuration, it is evenly equipped with the scallop hole of multiple hollow out.
Described built-in rotatable blades can rotate on boot of elevator, and the size of fanning strip just in time can cover scallop hole, and realization can fast sealing or open.
Advantage of the present invention is: after installing on jack-up unit, is reduced the contact area of shoe and ground in pitching pile process by hollow out frame form, reduces friction, reaches effective driving depth; Launched by shoe rotating vane after completing pitching pile, increase the contact area of shoe and ground, thus the restraint forces of a shoe balance and stability can be obtained rapidly, realize fast and stable and the balance of spud leg; After completing ocean operation task, shoe rotating vane can be packed up again, make shoe again become hollow out frame form, decrease the contact area with ground, reduce friction, reach the effect of effective pile pulling.This patent can solve the series of problems such as the installation of jack-up unit in various foundation of sea floor, stable, dismounting well, and manufacture craft is simple, easy to use, has very high application value.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
A kind of efficient controllable type jack-up unit shoe device, comprise boot of elevator 1, spud leg jacket casing 2, fluid pressure type locking torsion bar 3, built-in rotatable blades 4 and ultrasonic probe 5, it is characterized in that: in described spud leg jacket casing 2, be provided with fluid pressure type locking torsion bar 3, fluid pressure type locking torsion bar 3 is connected with built-in rotatable blades 4, realize the rotation to built-in rotatable blades 4, built-in rotatable blades 4 is arranged in boot of elevator 1, boot of elevator 1 is arranged on below spud leg jacket casing 2, boot of elevator 1 top is provided with ultrasonic probe 5, for detecting the flowing of earth near boot of elevator 1, ultrasonic probe 5 is connected with the control system on spud leg jacket casing 2, when there is liquefaction drift sand near one of them boot of elevator 1, the built-in rotatable blades 4 of other two boot of elevators 1 is opened simultaneously, realize together declining, prevent platform run-off the straight collapse accident.
Described built-in rotatable blades 4 is made up of multi-disc fanning strip.
Described boot of elevator 1 circular configuration, it is evenly equipped with the scallop hole of multiple hollow out.
Described built-in rotatable blades 4 can rotate on boot of elevator 1, and the size of fanning strip just in time can cover scallop hole, and realization can fast sealing or open, and realizes plug fast.
Using method of the present invention: in whole device, boot of elevator 1, spud leg copper sheathing 2 and fluid pressure type check lock lever 3 are all made with the high strength steel material that material density is high, the shoe frame 1 of hollow out form in the middle of adopting, object be can ensure in the pitching pile process of whole platform stake power leg in the silt of various seabeds more smooth.The low-alloy strength steel that the material that in the middle of boot of elevator 1, built-in rotatable blades 4 adopts is more hard, blade is smooth hard, turned on by hydraulic means after each spud leg of ocean platform reaches predetermined seabed depth and effectively cut in foundation of sea floor, and the screw-threaded coupling form of hydraulic jack is similar to by the fluid pressure type locking torsion bar 3 in stake power leg, ensure that shoe blade can tightly be locked better and be in effective deployed condition, increase effective contact area of whole shoe and ground, the operating position of stabilized platform, sees Fig. 2, Fig. 3; Above whole boot of elevator 1 device, base ultrasonic probe 5 and signal transceiver are also installed, the particular location of foundation of sea floor is inserted for measuring shoe, can signal be sent to receiver in real time thus adjust hydraulic-pressure control apparatus in time, ensure the balance of whole offshore platform structure and stablize.When self-elevating ocean platform complete need to withdraw after operation on the sea task time, locking torsion bar can be unclamped, pack up shoe blade, make again shoe frame 1 reach middle hollow out state, the object reaching smooth pile pulling with the contact friction of foundation of sea floor silt can be reduced well.
