Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with description of the drawings and specific embodiment.
As shown in Figure 1, a kind of ocean production riser oil-tube lifting-correcting device of the utility model, including by the first semi-circular branch
The annular support that 2 and second semi-circular supporter 3 of support body is detachably connected.Specifically combine Fig. 2, the support of the first semi-circular
The both sides edge of body 2 and the both sides of the second semi-circular supporter 3 edge are both provided with multiple locking arms 9, and the first semi-circular supports
Locking arm 9 on body 2 is interspersed with the locking arm 9 on the second semi-circular supporter 3, is respectively provided in each locking arm 9
There is locking pin hole 8, bolt 1 is provided in locking pin hole 8, is supported on the outer wall of the first semi-circular supporter 2 with the second semi-circular
It is respectively provided on the outer wall of body 3 there are two symmetrical righting arm 4, righting arm 4 preferentially selects rubber righting arm.
During oil pipe and auxiliary line tripping in production riser, first with the first semi-circular supporter 2 and the second semi-ring
Shape supporter 3 embraces oil pipe outer diameter to after just, bolt 1 being inserted into locking pin hole 8, by the first semi-circular supporter 2
Oil pipe is locked with the inner wall of the second semi-circular supporter 3, achievees the purpose that righting.The maximum outside diameter of righting arm 4 should be slightly less than
The internal diameter of production riser can thus rely on the flexible contact of four righting arms 4 and production riser inner wall preferably to realize oil pipe
With production riser to neutralizing centralizing function.
