Description
Technical field
The utility model relates to a kind of drilling equipment, particularly a kind of novel self-lifting type offshore boring island lifting mechanism.
Background technology
Self-elevating drilling platform claims again deck ascending/decending or spud leg formula platform.This oil drilling device loads drilling machinery, power, equipment, accommodation and some liftable spud legs on platform, and during drilling well, spud leg lands, and platform lifts away from sea certain altitude along spud leg; During displacement, platform is down to the water surface, and spud leg rises, and platform, just as barge, can drag new well location it by tugboat.
The most frequently used lifting gear of jack-up unit is pinion and-rack and jacking hydraulic cylinder type.Pinion and-rack can be realized continuous lifting, and speed is fast, flexible operation; But need complexity and huge reducing gear, volume is large, after platform hoists, with brake, is fixed, and elevating mechanism is always in stress, to having relatively high expectations of rack-and-pinion.Hydraulic pressure lifting mechanism does not need complicated gear, and volume is little, and transmission efficiency is high, and control ratio is more flexible; But lifting continuously, speed is slower, and troublesome poeration is had relatively high expectations to hydraulic oil and hydraulic valve piece.
The design's application turbine and worm mate gear engaged transmission, increased greatly gearratio, and saved installing space, motor can directly drive, and without control rate, regulates, and has adopted column type spud leg simultaneously, assembling screw thread can increase contact area arbitrarily, even whole spud leg can be made shape of threads, has effectively increased the support force of spud leg, realizes safety more reliable.
Utility model content
The purpose of this utility model is exactly for present situation, and a kind of novel self-lifting type offshore boring island lifting mechanism is provided, and overcomes the huge reducing gear of complexity of current lifting mechanism, and volume is excessive, and process is discontinuous, and speed is a little slower, and its technical scheme adopting is as follows:
A kind of novel self-lifting type offshore boring island lifting mechanism, comprise spud leg lower wall thrust bearing, motor, endless screw support, turbine pallet, special turbine, worm screw, novel spud leg, gear wheel, pinion, platform, spud leg lower wall, turbine pallet thrust bearing, described spud leg lower wall thrust bearing links novel spud leg and spud leg lower wall, described motor is connected with pinion, described endless screw support links by draw-in groove and platform, described turbine pallet is connected with special turbine by pallet thrust bearing, described worm screw is rack-mount, described gear wheel is connected with worm screw, described pinion is meshed with gear wheel and is arranged on motor,
The volume ratio that above-mentioned spud leg lower wall thrust axis is made is larger, and the weight that can bear platform, use be cylinder roller bearing;
Above-mentioned special turbine heart is not usual key slot type, but thread groove is equivalent to a large nut;
Above-mentioned turbine pallet inside remains screw threaded arrangement, and object is the weight that can carry spud leg, reduces the power of turbine carrying;
Above-mentioned turbine pallet thrust bearing is contained in spud leg lower wall, is mainly used in making two parts up and down that link to relatively rotate.
The utlity model has following advantage: adopt Worm Wheel System, mechanism is simple, weight saving, volume reduce, stable drive is reliable, mate gear transmission simultaneously can greatly improve gearratio, adopt motor direct-drive, saved the cost of control system, saved space, can also increase lifting surface area, make device intensity be enough to meet need of production.

Symbol description
1. spud leg lower wall thrust bearing, 2. motor, 3. endless screw support, 4. turbine pallet, 5. special turbine, 6. worm screw, 7. novel spud leg, 8. gear wheel, 9. pinion, 10. platform, 11. spud leg lower walls, 12. turbine pallet thrust bearings.
The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, the utility model self-elevating drilling platform lifting mechanism, comprise spud leg lower wall thrust bearing 1, motor 2, endless screw support 3, turbine pallet 4, special turbine 5, worm screw 6, novel spud leg 7, gear wheel 8, pinion 9, platform 10, spud leg lower wall 11, turbine pallet thrust bearing 12, described spud leg lower wall thrust bearing 1 links novel spud leg 7 and spud leg lower wall 11, described motor 2 is connected with pinion 8, institute's endless screw support 3 links by draw-in groove and platform 10, described turbine pallet 4 is connected with special turbine 5 by pallet thrust bearing 12, described worm screw 6 is arranged on support 3, described gear wheel 8 is connected with worm screw 6, described pinion 9 is meshed and is arranged on motor with gear wheel 8.
In work spud leg decentralization process, opening power, motor 2 rotates, and drives pinion 9 to rotate, pinion 9 is by meshing with gear wheel 8, thereby drive gear wheel 8 to rotate, gear wheel 8 rotates and drives worm screw 6 to rotate, and worm screw 6 drives special turbine 5 to rotate, owing to having screw thread in special turbine 5, by screw thread, novel spud leg 7 is rotated, thereby realize spud leg decentralization process, until arrive seabed.After arriving seabed, spud leg is not declining, and special turbine 5 still provides downward power, now because there is the existence of lower wall thrust bearing 1, spud leg is rotated further, offer the power that platform 10 makes progress, make platform 10 rise to our needed height, and then start drilling well.When needs are extracted spud leg, the course of work is contrary.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
