Abstract

The utility model relates to ocean oil equipment, in particular to a novel elevator mechanism of a self-elevating drilling platform. The elevator device which is often used by the self-elevating drilling platform is gear rack type or jacking hydraulic cylinder type. The elevator device of the gear rack type can realize consecutive elevation and is quid in speed and flexible in operation, but needs a complex and huge reducing mechanism and is large in size. Moreover, a brake is needed for fixation after the platform is elevated, an elevator mechanism is always in a stress state, and the requirements for a gear rack are high. A hydraulic elevator mechanism does not need a complex speed changing mechanism, is small in size, high in transmission efficiency and flexible to control, but is incapable of elevating consecutively, slow in speed and troublesome in operation, and requires high for hydraulic oil and hydraulic valve pieces. The novel elevator mechanism of the self-elevating drilling platform adopts thread transmission, and gear transmission and bevel gear transmission are used in a matching mode, so that the transmission ratio is greatly increased. A motor does not need speed adjustment, so that the elevating and lowering process is more stable, the overall mechanism is simpler, installation and operation are easier, and cost is reduced.

Description

Novel self-lifting type drilling platform lifting mechanism
Technical field
The utility model relates to a kind of equipment On The Offshore Platform, particularly a kind of novel self-lifting type drilling platform 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 engaged transmission that the design's application nuts and bolt coordinates, mate gear transmission and Bevel Gear Transmission, increased greatly gearratio, and saved installing space, motor can directly drive, without control rate, regulate, adopted column type spud leg, assembling screw thread can increase contact area arbitrarily simultaneously, and even whole spud leg can be made shape of threads, effectively increase the support force of spud leg, realized 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 structure is provided, and overcomes the huge reducing gear of complexity of current elevating mechanism, and volume is excessive, and process is discontinuous, and speed is a little slower, and its technical scheme adopting is as follows:
One novel self-lifting type drilling platform lifting mechanism, is characterized in that: comprise novel spud leg, interior screw thread gear wheel, pinion, support, power transmission shaft, motor, bevel pinion, bevel gear wheel, spud leg thrust bearing, gear thrust bearing, spud leg lower wall.On described novel spud leg, there is equally distributed screw thread everywhere to coordinate with interior screw thread gear wheel, described interior screw thread gear wheel engages with pinion, by gear thrust bearing, be arranged on platform, described pinion is arranged on power transmission shaft and engages with gear wheel, described support and power transmission shaft link by bearing, described motor is arranged on platform, described conelet tooth is arranged on motor, described bevel gear wheel is arranged on power transmission shaft, and engage with bevel pinion, described spud leg thrust bearing connects novel spud leg and spud leg lower wall, described gear thrust bearing links novel gear wheel and platform,
Above-mentioned spud leg thrust bearing links novel spud leg and spud leg lower wall, and the weight that can bear platform;
Above-mentioned interior screw thread gear wheel is equivalent to a large nut, by rotation, spud leg is moved up and down;
Above-mentioned platform and the place that novel spud leg contacts, be arranged as screw thread, and Main Function is the weight of bearing whole platform, the power of screw thread gear wheel carrying in reducing;
Above-mentioned bevel gear wheel and bevel pinion coordinate, and realize rotation direction and change, and certain gearratio is provided.
The utlity model has following advantage: adopt screw thread transmission, mechanism is simple, weight saving, volume reduce, stable drive is reliable, mate gear transmission simultaneously and Bevel Gear Transmission can greatly improve gearratio, adopt motor direct-drive, without reducing gear, control simple, save the cost of control system, saved space.

Symbol description
1. novel spud leg, 2. interior screw thread gear wheel, 3. pinion, 4. support, 5. power transmission shaft, 6. motor, 7. bevel pinion, 8. bevel gear wheel, 9. spud leg thrust bearing, 10. gear thrust bearing, 11. spud leg lower walls.
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 lifting mechanism of self-elevating drilling platform, comprises novel spud leg 1, interior screw thread gear wheel 2, pinion 3, support 4, power transmission shaft 5, motor 6, bevel pinion 7, bevel gear wheel 8, spud leg thrust bearing 9, gear thrust bearing 10, spud leg lower wall 11.On described novel spud leg 1, there is equally distributed screw thread everywhere to coordinate with interior screw thread gear wheel 2, described interior screw thread gear wheel 2 engages with pinion 3, by gear thrust bearing 10, be arranged on platform, described pinion 3 is arranged on power transmission shaft 5 and engages with gear wheel 2, described support 4 links by bearing with power transmission shaft 5, described motor 6 is arranged on platform, described conelet tooth 7 is arranged on motor 6, described bevel gear wheel 8 is arranged on power transmission shaft 4, and engage with bevel pinion 7, described spud leg thrust bearing 9 connects novel spud leg 1 and spud leg lower wall 11, described gear thrust bearing 10 links novel gear wheel 2 and platform.
In spud leg decentralization process, open motor power, motor 6 rotates, and drives bevel pinion 7 to rotate, bevel pinion 7 is by engaging with bevel gear wheel 8, thereby drive bevel gear wheel 8 to rotate, bevel gear wheel 8 rotates by power transmission shaft 5 and drives pinion 3 to rotate, pinion 3 drives special interior screw thread gear wheel 2 to rotate, owing to having screw thread in interior screw thread gear wheel 2, by screw thread, novel spud leg 1 is rotated, thereby realize spud leg decentralization process, until arrive seabed.After arriving seabed, spud leg is not declining, and interior screw thread gear wheel 5 still provides downward power, now because there is the existence of lower wall thrust bearing 10, spud leg is rotated further, offer platform power upwards, make platform 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.
