Abstract
The utility model relates to offshore oil drilling equipment, in particular to a folding blade pile shoe for a jack-up drilling platform. A plurality of folding blades are arranged around the main body of the folding blade pile shoe, the folding blades are connected with the main body of the pile shoe through a bidirectional hydraulic cylinder and a connecting mechanism, and the folding blades can be unfolded and folded inwardly under the driving of the bidirectional hydraulic cylinder. The folding blade pile shoe for the jack-up drilling platform is characterized in that the maximum vertical orthographic projection area can be provided when an operator works by standing on the drilling platform, the safety and the reliability for standing on the drilling platform are improved, and the pile drawing force is reduced with the minimum vertical orthographic projection area during pile drawing on the platform, thereby providing convenience for the pile to separate from the platform. The folding blade pile shoe for the jack-up drilling platform overcomes the disadvantage of the prior art that the pile drawing force cannot be reduced while the vertical orthographic projection area is increased.
Description
Technical field:
The utility model relates to a kind of offshore oil drilling equipment, the particularly folding blade shoe of a kind of self-elevating drilling platform.
Background technology:
Self-elevating drilling platform is the steel self lift type drilling rig of offshore oil natural gas exploration and development drillng operation, this kind offshore boring island contacts the normal pressure that produces by the shoe bottom and guarantees the safety and stability that platform is stood with the soil body when standing state, to guarantee the survival ability of platform under normal operation and extreme storm environment.
The self-elevating drilling platform shoe is the important structure that guarantees the platform stability of standing.The vertical frontal projected area of shoe is larger, and its vertical normal pressure that can provide is just larger, thereby reduces the shoe injection earth degree of depth, and spud leg length also can suitably shorten, and can reduce like this construction cost of platform, is favourable to platform.In addition, the vertical frontal projected area of shoe increases the over the ground specific pressure that can effectively reduce shoe, and offshore boring island is reduced the operating area Geological Condition Requirement, but enlarges offshore boring island operation marine site scope.But shoe needs can be recovered in the main hull stake trap, and shoe makes too greatly to such an extent that effective displacement of volume of main hull reduces, and the platform towing security reduces and the pile pulling power that can provide reduces.In addition, the pile pulling power of the larger shoe of the vertical projected area of shoe also can increase thereupon, pile pulling process difficulty.Existing offshore boring island shoe is difficult to solve above-mentioned contradiction.
The utility model content:
The technical problems to be solved in the utility model provides the folding blade shoe of a kind of self-elevating drilling platform, this device has realized providing the vertical frontal projected area of maximum in the platform standing at work, improve the safety and stability that offshore boring island is stood, and the vertical frontal projected area with minimum reduces pile pulling power in platform pile pulling process, is easy to platform and offs normal.Overcome the deficiency that reduces pile pulling power when existing shoe can not be accomplished to increase vertical frontal projected area.
Technical solution adopted in the utility model is: a kind of self-elevating drilling platform folds the blade shoe, comprises the shoe main body; The a plurality of folding blades of shoe main body arranged around, folding blade pass are crossed two-way hydraulic cylinder and are connected with the shoe main body with bindiny mechanism, and realize launching and inwardly folding under the driving of two-way hydraulic cylinder.
The beneficial effects of the utility model are: the utility model is owing to adopted the mode that connects a plurality of folding blades, thereby have and utilize folding blade effectively to adjust the function of the vertical frontal projected area size of shoe, be implemented in the vertical frontal projected area that can provide maximum in the platform standing at work, improve the safety and stability that offshore boring island is stood, and the vertical frontal projected area with minimum reduces pile pulling power in platform pile pulling process, is easy to platform and offs normal.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of self-elevating drilling platform folds the blade shoe, comprises shoe main body 1; The a plurality of folding blades 2 of shoe main body 1 arranged around, folding blade 2 are connected with bindiny mechanism by two-way hydraulic cylinder 3 and are connected with shoe main body 1, and realize launching under the driving of two-way hydraulic cylinder 3 and inside folding.
On the shoe main body 1 three short side directions respectively be provided with mind-set extension therefrom vertical rib disc and with the welding of spud leg chord member, three long side directions outsides respectively are provided with a folding blade 2, make it can be along rotating under the outside of shoe main body 1.Each folding blade 2 lower end is provided with altogether three bindiny mechanisms 4 and links to each other with edge under shoe main body 1 outside in both sides and centre, folding blade 2 upper end correspondences are provided with altogether three bindiny mechanisms 4 in both sides with the centre and link to each other with the piston rod of three two-way hydraulic cylinders 3 respectively, the cylinder barrel of two-way hydraulic cylinder 3 is positioned at shoe main body 1, and can in vertical plane, slightly rotate round cylinder barrel and intersection, shoe main body 1 outside, to be fit to the folding and unfolding of folding blade 2.
Blade launched extreme position horizontal by 30 ° of angles horizontal by being bordering on plumbness when folding blade 2 of the present utility model was regained, and can effectively increase vertical frontal projected area 58.5% this moment, and can adjust the mounted blade angle according to actual pitching pile needs.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
