The size of the annular gap is slightly larger than the wall thickness of a waterproof guide pipe. The thickness of the inner wings is equal to the wall thickness of the waterproof guide pipe. The maritime waterproof guide pipe pile capping device can be widely applied to maritime petroleum drilling and other maritime engineering piling operations.
Description
Technical field
The utility model relates to a kind of pile follower device, particularly about a kind of marine riser pipe pile follower device.
Background technology
In the work progress of oil drilling riser pipe, usually adopt the mode of pile hammer piling that riser pipe is hammered into to the expectation degree of depth at sea.For preventing that in the piling process, the riser pipe top deforms under the pile hammer effect, therefore need to add in the riser pipe upper end pile follower.On the one hand, although existing riser pipe pile follower can be avoided the riser pipe distortion to a certain extent, because its inside is hollow-core construction, provide support to the riser pipe inwall, therefore, in piling work, often can occur the riser pipe top destroyed and the distortion phenomenon; On the other hand, the contact surface that transmits power due to existing pile follower is little, makes the power transmission of pile hammer inhomogeneous, thereby causes in the piling process phenomenon that occurs that pile follower and riser pipe tilt, and the regional area at riser pipe top is damaged.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of marine riser pipe pile follower device, this pile follower device can make the riser pipe in the piling process pour equably underground, the situation that minimizing causes riser pipe to be out of shape because of the stressed bias of pile follower body, thereby the operation of assurance marine guidance piling is carried out smoothly, guarantees piling quality.
For achieving the above object, the utility model is taked following technical scheme: a kind of marine riser pipe pile follower device, it is characterized in that: it comprises a top closure and inner wing on the open inner sleeve on the open outer sleeve in bottom, sealing surface that a top is fixed on described outer sleeve top and bottom and some inner tube walls that is fixed on described inner sleeve, between the inner tube wall of described outer sleeve and the outer tube wall of described inner sleeve, has annular gap.
Described some inner wings be take the central axis of described inner sleeve and uniformly-spaced are fixed on equably on the inner tube wall of described inner sleeve as axle center.
The quantity of described inner wing is eight.
The thickness of described annular gap is greater than the wall thickness of riser pipe.
The thickness of described inner wing equals the wall thickness of riser pipe.
The bottom of described outer sleeve is set to the horn mouth shape.
Thick 1.5 times of being the riser pipe wall thickness of cylinder of described outer sleeve and inner sleeve.
The internal diameter of described outer sleeve is than the large 2mm of the external diameter of riser pipe, and the external diameter of described inner sleeve is than the little 2mm of the internal diameter of riser pipe.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model be take the central axis of inner sleeve and uniformly-spaced is fixed on equably on the inner tube wall of described inner sleeve as axle center due to some inner wings, some described inner wings can support the inner tube wall of described inner sleeve well, thus the utility model can guarantee it in the situation that uniform stressed that riser pipe is poured equably is underground.2, there is annular gap between the outer tube wall of the utility model due to the inner tube wall of its outer sleeve and inner sleeve, the size in described gap is greater than the wall thickness of riser pipe, therefore the utility model can reduce due to the eccentric situation that causes the riser pipe distortion of piling, thereby increase the application life of riser pipe, the operation of assurance marine guidance piling is carried out smoothly, guarantees piling quality.3, the utility model because it comprises a top closure inner wing on the open inner sleeve on the open outer sleeve in bottom, sealing surface that a top is fixed on described outer sleeve top and bottom and some inner tube walls that is fixed on described inner sleeve, therefore the utility model processing is simple, can save processing cost.Based on above advantage, the utility model can be widely used in offshore petroleum drilling and other marine engineering piling work.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is front elevation drawing of the present utility model
Fig. 3 is upward view of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in FIG. 1 to 3, the utility model comprises an outer sleeve 1, an inner sleeve 2 and several inner wings 3.Wherein, outer sleeve 1 is the open cylindrical shell in a top closure and bottom.In the present embodiment, for ease of the utility model is enclosed within on riser pipe, bottom that can outer sleeve 1 is set to the horn mouth shape.Inner sleeve 2 is arranged in outer sleeve 1 coaxially, and the top of inner sleeve 2 is fixed on the sealing surface on outer sleeve 1 top, and its bottom is open.Simultaneously, between the outer tube wall of the inner tube wall of outer sleeve 1 and inner sleeve 2, exist the thickness of certain ，Gai annular gap, annular gap to be slightly larger than the wall thickness of riser pipe.Several inner wings 3 be take the central axis of inner sleeve 2 and uniformly-spaced are fixed on equably on the inner tube wall of inner sleeve 2 as axle center.
When the utility model is enclosed within on riser pipe, riser pipe is fixed in the gap between the outer tube wall of the inner tube wall of outer sleeve 1 and inner sleeve 2.The inner sleeve 2 supported by several inner wings 3 can provide the inner transverse reaction of bearing for riser pipe, avoids the riser pipe lateral deformation.Several inner wings 3 can support the inner tube wall of inner sleeve 2 well, guarantee the utility model in the situation that uniform stressed can to make riser pipe pour equably underground, minimizing is due to the eccentric situation that causes the riser pipe distortion of piling, thereby extend the application life of riser pipe, the operation of assurance marine guidance piling is carried out smoothly, guarantees piling quality.
In a preferred embodiment, the external diameter of the riser pipe of selecting is 762mm or 610mm, and the wall thickness of riser pipe is 25.4mm.The length of outer sleeve 1 is set to 750mm, and the outer sleeve 1 bell-mouthed external diameter in bottom is than the large 100mm of the external diameter of riser pipe.Thick 1.5 times of being the riser pipe wall thickness of cylinder of outer sleeve 1 and inner sleeve 2, the internal diameter of outer sleeve 1 is than the large 2mm of the external diameter of riser pipe, the external diameter of inner sleeve 2 is than the little 2mm of the internal diameter of riser pipe, thereby makes the upper end of the utility model and riser pipe can be good at agreeing with.
In a preferred embodiment, eight inner wings 3 be take the central axis of inner sleeve 2 and uniformly-spaced are welded on equably as axle center on the inner tube wall of inner sleeve 2, and the thickness of inner wing 3 equals the wall thickness of riser pipe.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
