Abstract
The utility model relates to a jack-up retractable fin pile shoe for a drilling platform, which consists of a pile shoe main body, retractable fins, a two-way hydraulic cylinder and telescopic guide blocks; the periphery of the upper edge of the pile shoe main body is uniformly placed with a plurality of retractable fin slots, and each of the retractable fin slots is provided with a retractable fin, the front ends of the retractable fins are provided with the telescopic guide blocks; the two-way hydraulic cylinder is arranged in the center of the pile shoe main body, the hydraulic power is provided by a hydraulic station on the platform and is transported through a hydraulic pipeline; the retractable fins can be extended or retracted through the driving of the two-way hydraulic cylinder. The jack-up retractable fin pile shoe has the advantages of rational design, novel structure, easy operation and reliable working; by using the pile shoe of the utility model, the orthographic projection area size of the pile shoe can be reasonably changed by adjusting the retractable fins, thereby achieving the purposes that according to the actual needs, the vertical bearing capacity of the pile shoe is controlled and the stability and security of the drilling platform are improved.
Description
Technical field:
The utility model relates to a kind of supporting mechanism that is used for the offshore oil drilling equipment, belongs to offshore oil drilling equipment technology class.
Background technology:
Self-elevating drilling platform is the basis and the important equipment of offshore oil drillng operation, and the stability that this kind offshore boring island comes support platform to stand by the frictional force and the normal pressure of spud leg and shoe when standing state is to guarantee the normal running and the production work of platform.Shoe is generally circle or regular polygon, and its shape and size are calculated and designed according to the required bearing capacity of platform.The shoe of self-elevating drilling platform is the important structure form that guarantees that platform is stood stable, the vertical projected area of shoe is big more, the vertical normal pressure that it provided is big more, thereby can reduce the degree of depth that spud leg inserts mud layer, the length of spud leg also can suitably shorten, and cost and the changing load to platform is all favourable like this.But shoe too greatly also can influence shoe and be recovered in the main hull, makes the dischargeable capacity of main hull reduce, and in addition, the vertical variation projected area of shoe is big more, and the pitching pile of its spud leg and pile pulling process are just difficult more.Existing offshore boring island shoe is difficult to satisfy the needs that solve above-mentioned contradiction.
The utility model content:
The purpose of this utility model be to provide a kind of in the offshore boring island standing at work, can provide maximum vertical projected area to guarantee platform stable in platform pitching pile, pile pulling process vertical projected area minimum to make things convenient for the flexible fin shoe of platform self-elevating drilling platform in place and displacement.
The purpose of this utility model is to realize like this.The flexible fin shoe of this kind is made up of shoe main body, flexible fin, two-way hydraulic cylinder, flexible guide pad, its structural relation is as follows: in the uniform actiniform a plurality of flexible fin grooves of shoe main body upper edge periphery a flexible fin that can stretch is set respectively, flexible fin front end is provided with flexible guide pad, shoe main body central authorities are provided with two-way hydraulic cylinder, hydraulic power derives from the Hydraulic Station on the platform, carry by hydraulic line, flexible fin can stretch out or withdraw under two-way hydraulic cylinder drives.The flexible fin shoe of this kind is arranged on the drilling platform leg below, and its operating principle is as follows; During the platform towage, the fin that will stretch is all taken in the shoe body interior, makes shoe projected area minimum, can guarantee that shoe takes in platform stake trap inside fully, guarantees towage safety, adapts to shallow water operations; The platform pitching pile operation initial stage is that shoe is can touch ocean mud face the time, driving hydraulic means releases flexible fin, effectively increase the shoe area, flexible length can be incorporated into the mud depth calculation in advance according at that time edaphic condition and required bearing capacity and shoe, the shoe that increases area is inserted, obtain enough supporting capacitys; When platform carries out the pile pulling operation, carrying out after the short time dashes stake, the operation hydraulic means fin that will stretch is withdrawn in the shoe, carries out the necessary stake operation of dashing again, then the shoe of reduced projection area is more easily pulled out.
The utility model is reasonable in design, novel structure, easy operating control, reliable operation, utilize this kind shoe rationally to change shoe frontal projected area size by adjusting flexible fin stroke, it is controlled and improve the purpose of offshore boring island stability and safety to make it reach the shoe vertical bearing capacity according to actual needs.
Description of drawings:
Fig. 1, Fig. 2 are respectively the plan structure schematic diagram of the utility model when regaining and stretching out state.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of shoe main body 1, flexible fin 2, two-way hydraulic cylinder 3, flexible guide pad 4, wherein, shoe main body 1 is regular polygon (legend is an octagon) or circular trapezoidal discoid body, respectively be provided with the flexible flexible fin groove of the flexible fin of a confession within it corresponding to each bar limit on it, integral body is the dislocation radiation.Flexible fin 2 is telescopic wedge shape case shape steel structure body, big by shoe central authorities one end, the outer end is little, its side is trapezoidal, inside is suitably strengthened with the material of aiding the strong, and can stretch out from the shoe body interior when stretching out state, and extension elongation is according to the shoe size design, generally be equivalent to 1/3 of shoe radius, under retracted mode, can take in the shoe body interior fully.Two-way hydraulic cylinder 3 is made up of cylinder body, piston and connecting rod.Flexible guide pad 4 is arranged on flexible fin both sides, matches with flexible fin and flexible fin groove respectively, and suitably strengthens with the material of aiding the strong.
