Compared with the prior art, the utility model adopts components integration mode, and has the advantages of simple structure, convenient installment and disconnection, easy operation and high dependability.
Description
Technical field
The utility model relates to a kind of marine drilling system, relates to a kind of self-elevating drilling platform jacking system especially.
Background technology
At the various ocean platforms that are used for marine petroleum development and other marine structures, jack-up unit relatively is suitable for neritic province domain, it is few to have steel using amount, cost is low, completion waterborne, almost can both continuous operation and efficient advantages of higher under various sea situations, jack-up unit is when operation, put down spud leg and insert the seabed certain depth, thereby platform is held out the water surface, become spar deck, after the operation, fall platform, pull up spud leg, get final product towage to new place, therefore, in seafari at home and abroad and the exploitation, particularly in the coastal ocean oil development, brought into play enormous function.Jacking system is as the key component in the jack-up unit, always paid much attention to the good and bad safety and the result of use that directly influences platform of its performance in the manufacturing and designing of platform.The jacking system of jack-up unit roughly is divided into two big classes at present: pinion and-rack and hydraulic jack jacking type.Than the jacking system of hydraulic jack jacking type, the pinion and-rack rising or falling speed is fast; Simple to operate; Easily to well location.
Because the marine environment condition is relatively abominable, the length of lifting platform required time just seems particularly important to platform security, therefore the jack-up unit of newly making adopts the rack-and-pinion up-down mode more, and for this mode, in design process, often only pay attention to reliability at present, to the durability of system, the convenience of implementing be installed how do not consider, and this for cost higher and can nonexpondable system for, will cause bigger waste.
Summary of the invention
The technical problems to be solved in the utility model is: providing a kind of is the self-elevating drilling platform lifting drive system of up-down mode with the rack-and-pinion, and this entire system performance is good, easy for installation and reliability is high.
Mentality of designing of the present utility model is: on every pile leg of platform some toothed rack are set, be provided with the gear that is engaged with corresponding to every toothed rack, tooth bar and corresponding gear quantity thereof are determined according to desired jacking capacity of platform and platform general requirement.Power passes to and the tooth bar meshed gears then by the motor drive gear reduction box, thereby drives the lifting of platform.
The utility model is realized by following technical proposals:
A kind of self-elevating drilling platform rack-and-pinion jacking system, be fixed on the offshore boring island, comprise Power Drive Unit, platform rack-and-pinion apparatus for controlling of lifting and main structure body, described main structure body is connected with offshore boring island, described Power Drive Unit, platform rack-and-pinion apparatus for controlling of lifting is fixed on the main structure body, described platform rack-and-pinion apparatus for controlling of lifting comprises shaft gear and is fixed on spud leg tooth bar on the drilling platform leg, described shaft gear and the engagement of spud leg tooth bar, described shaft gear is connected with described Power Drive Unit output.
Further, this system also comprises a power transmission, and described power transmission is arranged between the input of the output of Power Drive Unit and platform rack-and-pinion apparatus for controlling of lifting.
Further, one or an above self-elevating drilling platform rack-and-pinion jacking system are set simultaneously on the described spud leg.
Further, described Power Drive Unit is a motor.
Further, described power transmission is a gear-box.
Further, described gear-box is a gear reduction box.
Further, described gear-box be set to single-stage or connect successively multistage.
Compared with prior art, the system that the utility model proposed, the mode of employing component set makes structure more simple, easy installation and removal, simple to operate, reliability is also very high.
Description of drawings
Fig. 1 is the drive system structure front view of the utility model specific embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The utility model is further introduced below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
With reference to illustrated in figures 1 and 2, offshore boring island rack-and-pinion jacking system comprises: shaft gear 1, spud leg tooth bar 2, primary structural component 3, first order gear-box 4, shaft joint 5, second level gear-box 6, driven wheel 7, motor 8, final drive shaft 10, be installed on the offshore boring island, motor 8, first order gear-box 4, second level gear-box 6 all are fixed on the primary structural component 3, final drive shaft 10 also is fixed on the primary structural component 3 to supporting, shaft gear 1 and driven wheel 7 all are arranged on the final drive shaft 10, and spud leg tooth bar 2 is arranged on the spud leg 9 of platform.The output shaft of motor 8 is connected with power shaft in the first order gear-box 4 by shaft joint, the output shaft of first order gear-box 4 links to each other with the power shaft of second level gear-box 6 by shaft joint 5, travelling gear in the second level gear-box 6 and driven wheel 7 engagements, driven wheel 7 motions, shaft gear 1 rotates, shaft gear 1 and 2 engagements of spud leg tooth bar.
First order gear-box 4 all adopts reduction gear box with second level gear-box 6, the purpose that adopts multiple reduction gear box is in order to obtain bigger driving torque and gearratio more accurately, and driving torque and gearratio are determined according to the general requirement of desired jacking capacity of platform and platform.
This device is installed on the offshore boring island, when motor 8 starts, its power transmission shaft that directly drives in the first order gear-box 4 rotates, driving second level gear-box 6 middle gears thus rotates, because gear of output end and driven wheel 7 engagements in the second level gear-box 6, thereby its motion drives the rotation of driven wheel 7, thereby shaft gear 1 rotates, thereby by the engaged transmission effect of shaft gear 1 with spud leg tooth bar 2, drive the action of spud leg 9, rotating by motor 8 can realize that the lifting both direction of spud leg 9 moves, thus the implementation platform lifting.
As shown in the figure, in the present embodiment, be symmetrically arranged with two groups of offshore boring island rack-and-pinion jacking systems on the main structure body 3, better guaranteed spud leg stress equalization, reasonable, help reducing the spud leg distortion, strengthen its durability,, can also require to increase the number of offshore boring island rack-and-pinion jacking system according to reality if the desired jacking capacity of platform is bigger.
