Description
Technical field
The utility model relates to a kind of elevating mechanism of self-elevating drilling platform, particularly a kind of chain elevating mechanism of column type spud leg.
Background technology
Offshore self-elevating drilling platform is mainly realized the lifting of working platform by spud leg and elevating mechanism thereof, meet the job requirements of drilling well or towage with this.Jack-up unit spud leg has two kinds of fundamental types: truss type spud leg and column type spud leg.Wherein, the elevating mechanism of column type spud leg mainly adopts fluid pressure type, need the co-ordinations such as multiple hydraulic cylinders, main oil pump, low pressure fuel pump, accumulator, needs complexity and accurately control system, failure-frequency is higher with respect to electric drive, and therefore the manufacture of fluid pressure type spud leg lifting mechanism and maintenance cost are higher; It need to be equipped with special Hydraulic Station, thereby it is larger to take working platform area; The lifting platform time is longer, in the more severe situation in the relative land of marine environment, is unfavorable for platform security.
Utility model content
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of mechanism that realizes spud leg elevating movement that coordinates by chain slide block is provided, it has overcome hydraulic lifting system manufacture and the shortcoming such as maintenance cost is high, floor space is large, lifting time is long, and its technical scheme adopting is as follows:
A kind of lifting mechanism of self-elevating drilling platform, comprise spud leg, upper spud leg slide block, slide rail, junction plate, bracing frame, sprocket wheel, chain, chain slide block guide rail, chain slide block, chain slide block cylinder, driving gear, driven gear, lower spud leg slide block, upper pile leg slide block, lower spud leg slide block and spud leg interact, and be arranged on slide rail, described junction plate and upper spud leg slide block, lower spud leg slide block connects, described sprocket wheel is arranged on bracing frame axle, described sprocket wheel coordinates with chain, described chain slide block guide rail is connected with bracing frame, described chain is connected with chain slide block cylinder, described chain slide block cylinder is arranged on chain slide block inside can scroll-up/down, described junction plate is connected with chain slide block, described sprocket wheel is arranged on bracing frame same axis with corresponding driven gear, described driving gear coordinates with driven gear.
The utlity model has following advantage: adopt sprocket wheel chain drive, simple in structure, the process that hoists is steadily reliable, has reduced manufacture and maintenance cost; The process that hoists is continuous, has reduced the process required time that hoists; Adopt the chain drive of bilateral sprocket wheel, can reduce the pressure-bearing of single rack and individual gears, increased the process stability that hoists simultaneously; Can adopt electric drive, not need Hydraulic Station, save floor space.

The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1-2, the utility model lifting mechanism of self-elevating drilling platform, comprise spud leg 1, upper spud leg slide block 2, slide rail 3, junction plate 4, bracing frame 5, sprocket wheel 6, chain 7, chain slide block guide rail 8, chain slide block 9, chain slide block cylinder 10, driving gear 11, driven gear 12, lower spud leg slide block 13, upper pile leg slide block 2, lower spud leg slide block 13 interacts with spud leg 1, and be arranged on slide rail 3, described junction plate 4 and upper spud leg slide block 2, lower spud leg slide block 13 connects, described sprocket wheel 6 is arranged on bracing frame 5 axles, described sprocket wheel 6 coordinates with chain 7, described chain slide block guide rail 8 is connected with bracing frame 3, described chain 7 is connected with chain slide block cylinder 10, described chain slide block cylinder 10 is arranged on chain slide block 9 inside can scroll-up/down, described junction plate 4 is connected with chain slide block 9, described sprocket wheel 6 is arranged on bracing frame 5 same axises with corresponding driven gear 12, described driving gear 11 coordinates with driven gear 12.
Bracing frame 5 is fixed on platform, can with spud leg 1 relative motion.In the time of work, power is inputted from driving gear 11, drive driven gear 12 to rotate, driven gear 12 drives coaxial sprocket 6 to rotate, sprocket wheel 6 drives are mated chain 7 and rotate, chain 7 drives are connected chain slide block cylinder 10 and move with it, chain slide block cylinder 10 is arranged on chain slide block 9 inside, drive its motion, chain slide block cylinder 10 chain slide block 9 is interior can scroll-up/down, thereby chain slide block 9 can realize commutation automatically at chain 7 two ends, chain 7 moves back and forth and is converted into the straight reciprocating motion of chain slide block 9 on chain slide block guide rail 8.In the time that spud leg hoists, upper spud leg slide block 2, lower spud leg slide block 13 are by mechanical locked, make its relatively spud leg 1 move downward, in the time that chain slide block 9 moves near spud leg 1, upper spud leg slide block 2 is motionless, lower spud leg slide block 13 is descending, in the time that chain slide block 9 moves away from spud leg 1, upper spud leg slide block 2 is descending, and lower spud leg slide block 13 is motionless, so repeatedly, realizing spud leg 1 hoists; In like manner, in the time that spud leg declines, upper spud leg slide block 2, lower spud leg slide block 13 is locked by machinery, make its relatively spud leg 1 move upward, can realize spud leg 1 and decline.
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.
