Technical background
At present, marine jack-up platform jacking system adopts pinion and-rack and fluid pressure type more.With No. 3 platforms of Shengli Oil Field is example (specifically can consult ' Wang Yunan: Jack-up System Design of Shengli Work-over Platform ' " in April, 2003, Chinese platform, the 18th volume, the 2nd phase "), and its basic structure is:
Every pile leg symmetric arrangement two toothed rack are arranged with two gear tank towers (wedge bracket), and three groups of HM Hydraulic Motor transmission devices are installed on each gear tank tower, comprise parts such as HM Hydraulic Motor, epicyclic reduction gear, miniature gears, brake system.Two gear tank towers and wedge bracket form a closed circle, with the spud leg cover therein.Power passes to and tooth bar ingear miniature gears then by stake limit motor driven gear reduction box, thereby drives lifting platform (seeing also shown in Figure 1).
The pinion and-rack manufacture process requirement is higher, and the special steel material of making this equipment is present also very in short supply; Hydraulic pressure is higher to technical requirements, produces to be difficult for realizing.
The utility model content
The purpose of this utility model is to provide a kind of drilling well that can be applicable to sea or other operation at sea, well workover, test, relevant flat-bed jacking systems such as oil recovery.
For achieving the above object, the jacking system that the utility model provides, it mainly comprises:
Article at least three, spud leg, vertical sleeve is located in the platform;
Be fixed with at least two group spud leg fixed pulleys along each spud leg one circle, every group of spud leg fixed pulley is two, is separately fixed at the upper and lower part of spud leg with dividing equally angle;
Platform respectively is equipped with a platform fixed pulley near the corresponding spud leg fixed pulley place, end top and bottom of spud leg, forms platform fixed pulley group; Corresponding each the platform fixed pulley group of this flat-bed other end is mounted with a winch, and the hawser on this winch is arranged between spud leg fixed pulley group and the platform fixed pulley group.
Described jacking system, wherein the cross-sectional plane of spud leg is a different shape.
Described jacking system wherein is equipped with computing machine and signal monitoring feedback system on the platform.
Described jacking system, wherein winch is provided with latching device.
Described jacking system wherein has the multiple tracks pulley groove on each pulley, and the hawser on the winch repeatedly is arranged between corresponding spud leg fixed pulley and the platform fixed pulley back and forth, and the power that can bear of assembly pulley will be the several times of the power that can bear of a rope like this.
Described jacking system, wherein the hawser on the winch is the rope made from steel rope or chain or other synthetic materiaies
By above-mentioned jacking system, motion platform or spud leg can make more producers can reach the ability of production platform jacking system simultaneously easily, solve present equilibrium of supply and demand problem, have also reduced cost simultaneously.
Description of drawings
Fig. 1 is a known technology lifting platform system schematic.
Fig. 2 is a lateral plan of the present utility model.
Fig. 3 is a birds-eye view of the present utility model.
The specific embodiment
Please in conjunction with Fig. 2 and 3, main body of the present utility model is to be bracing frame by several spud legs 1, vertically is sheathed in the platform 2.Around every 1 one weeks of spud leg, be fixed with three groups of spud leg fixed pulleys 30 with dividing equally angle; The cross-sectional plane of spud leg 1 can be a different shape, if quadrangle, then every spud leg can cooperate one group in each face totally four groups of assembly pulleys and winch, if the spud leg cross section is other polygons or the circular quantity that also can decide assembly pulley and winch according to the intensity needs, generally be provided with two groups at least, spud leg is subjected to equilibrium of forces when guaranteeing its application of force.Have the multiple tracks pulley groove on each pulley, repeatedly be arranged in repeatedly back and forth between the cooresponding pulley for rope, the power that can bear of assembly pulley will be the several times (wear back and forth in theory and be several times several times) of the power that can bear of a rope like this.The quantity of concrete each pulley top sheave groove and the number of times that rope wears are repeatedly back and forth decided by magnitude of load and line strength.The transversal surface that present embodiment shows with Fig. 3 is that the triangle spud leg is the example explanation, fixes one group of spud leg fixed pulley on each face of triangle spud leg.Every group of spud leg fixed pulley is made up of two fixed pulleys again, is separately fixed at the upper and lower part of spud leg 1, i.e. the upper side of platform 2 and downside (as shown in Figure 2).At the end of platform 2 by spud leg 1, side and downside are fixed with platform fixed pulley 31 and 32 respectively thereon with dividing equally angle; The other end of platform 2, its upper side and downside are divided equally angle ground and are fixed with three winches 6 respectively.The platform fixed pulley 31 of platform 2 upper sides concerns with the corresponding one by one one-tenth of spud leg fixed pulley 30 vertical lines on spud leg top respectively, (this hawser 5 can be the hawser that steel rope or chain or other synthetic materiaies are made to its each winch 6 by hawser 5, concrete which kind of rope that adopts, by intensity, weight, the life-span of cord material, stormy waves, the depth of water in work waters, the length and the economy of spud leg are taken all factors into consideration) wear around a corresponding platform fixed pulley and a spud leg fixed pulley for several times back and forth.The platform fixed pulley 31 of platform 2 downsides concerns that with the corresponding one by one one-tenth of spud leg fixed pulley 30 vertical lines of spud leg bottom its each winch 6 is worn around a corresponding platform fixed pulley and a spud leg fixed pulley back and forth by hawser 5 for several times respectively.By winch pulling hawser, realize the relative lifting of spud leg peace interstation.
The utility model principle of work is that each spud leg is by each three totally three groups of pulleys realization liftings up and down.When the relative platform of spud leg rises, start three winches of platform downside, the rolling hawser spurs the fixed pulley of spud leg bottom fixed pulley and platform downside, unclamps the hawser of three winches of platform upper side simultaneously, at this moment be support with the buoyancy of hull, spud leg is gone up in the sea.
When the relative platform of spud leg descends, start three winches of platform upper side, the rolling hawser spurs the fixed pulley of spud leg top fixed pulley and platform upper side, unclamps the hawser of three winches of platform downside simultaneously, makes spud leg drop to the predetermined degree of depth.
When the relative platform of spud leg is made rising or down maneuver, horizontal stroke, the trim of the signal control jacking condition lower platform of the signal monitoring feedback system of passing through by computing machine 4, the rising or falling speed of spud leg or hull, and the purpose of the working load that single pile bore, to guarantee elevating safety, stable carrying out, additional simultaneously latching device positions spud leg or platform.Computing machine and signal monitoring feedback system that the utility model adopts, and its structure of latching device and principle of work be known technology, promptly widely-used at present marine jack-up platform, therefore it is not described specifically.
