The ocean drill pipe thread joint comprises an outer thread joint body and an inner thread joint body which are connected with each other in a threaded mode; the end of the outer thread joint body extends to the inner side to form a connecting ring surface, and the connecting ring surface is provided with an annular positioning groove; the inner wall of the inner thread joint body extends to form a connecting channel of a truncated cone-shaped structure, and the outer side end of the connecting channel is inserted into the positioning groove in the connecting ring surface. According to the ocean drill pipe thread joint connected stably and firmly, the end of the outer thread joint body extends to the inner side to form the connecting ring surface, the connecting ring surface is provided with the annular positioning groove, the outer side end of the connecting channel is inserted into the positioning groove in a matched mode, and therefore the loading capacity of the thread joint of the outer thread joint body and the inner thread joint body is dispersed; in addition, the longitudinal sectional view of the connection of the inner wall of the inner thread joint body, the connecting ring surface and the connecting channel is of a triangular structure, and therefore the connection of the outer thread joint body and the inner thread joint body is more stable and firmer.
Description
Technical field
The present invention relates to marine petroleum exploitation equipment, particularly the structure of drill rod threaded nipple.
Background technology
At present, marine petroleum exploitation generally adopts oil drill rocker, oil drill rocker carries out end-to-end connection by nipple, and nipple generally comprises male connection and female adapter, and male connection and female adapter carry out end-to-end connection by screw thread.But; oil drill rocker is when drilling well; mainly bear the combined loads such as torsion, tension and compression, bending, vibration; harsh to the connection request between oil drill rocker like this; when the oil drill rocker of prior art carries out recover petroleum, the nipple place of oil drill rocker often can occur to connect and misplace built on the sand, and replacement cost is large; and exchonge step is loaded down with trivial details, have a strong impact on the operating efficiency of oil drill rocker.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the present invention solves is: drill rod threaded nipple connects built on the sand.
For solving the problem, the technical scheme that the present invention takes is as follows:
An ocean drill rod threaded nipple for stable connection, comprises male connection and female adapter; Described male connection and female adapter are threaded; Described male connection end is extended one to the inside and is connected anchor ring; Described connection anchor ring is provided with the detent of annular; The inwall of described female adapter extends the interface channel of a truncated cone-shaped structure; The outboard end of described interface channel is plugged in the detent on connection anchor ring.
Further, the outside of described male connection is provided with spacing ring block; Conflict on spacing ring block in described female adapter end.
Further, described spacing ring block is provided with the first inclined plane; The first described inclined plane tilts to the connection toroidal direction of male connection end.
Further, described female adapter end is provided with the second inclined plane; Conflict with the first inclined plane and be connected in described second inclined plane.
Further, the second described inclined plane is consistent with the incline direction on the first inclined plane.
Further, the second described inclined plane comprises contact inclined-plane and is connected inclined-plane; The inner side on contact inclined-plane is located on described connection inclined-plane; Described contact inclined-plane and the incline direction on the first inclined plane are always; Described connection inclined-plane is contrary with the incline direction contacting inclined-plane.Described connection inclined-plane, between the first inclined plane and male connection lateral surface, form annular space.
Further, the inner side on described connection inclined-plane is provided with support ring block; Described support ring block and male connection lateral surface recline.
Further, the longitudinal cross-section structure triangular in shape of described support ring block.
Further, sealing ring is provided with in described detent.
Beneficial effect of the present invention
1. extend one in male connection end to the inside and connect anchor ring, connect detent anchor ring being arranged annular; The inwall of female adapter extends the interface channel of a truncated cone-shaped structure, and the outboard end of interface channel is plugged in the detent on connection anchor ring.The outboard end of interface channel and the cooperation grafting of detent make the load force of the connection of thread of male connection and female adapter be disperseed.And the inwall of female adapter, connect anchor ring, structure that longitudinal sectional view that these three parts of interface channel connect is triangular in shape, utilize leg-of-mutton stability, thus make the connection of male connection and female adapter more firm.
2., at the spacing ring block of arranged outside of male connection, is conflicted on the spacing ring block in female adapter end.First can conflict due to the rotation of screw thread spacing ring block in female adapter end, spacing ring block also can produce an active force by internal threads fitting end, the axial load power of dispersion male connection and female adapter, what male connection was connected with female adapter is more firm.
3. spacing ring block is provided with the first inclined plane, and the first inclined plane tilts to male connection end direction.Such structure makes to produce radial load between male connection and female adapter, the axial load of dispersion male connection and female adapter.
4. female adapter end is provided with the second inclined plane, conflicts with the first inclined plane and be connected in the second inclined plane.Such structure further increases between male connection and female adapter and produces radial load, the axial load of dispersion male connection and female adapter.
5. the second inclined plane comprises contact inclined-plane and is connected inclined-plane, connects the inner side that contact inclined-plane is located on inclined-plane; Contact inclined-plane and the first incline direction tilted always, connect inclined-plane contrary with the incline direction contacting inclined-plane.Such structure makes to produce space between female adapter end and male connection lateral surface, thus decrease the weight of female adapter end, male connection is made to be more prone to the effect of internal threads joint generation radial load, further increase the steadiness of male connection and female adapter, also further disperse the axial load of male connection and female adapter simultaneously.
6. the inner side connecting inclined-plane arranges a support ring block, and support ring block and male connection lateral surface recline.The effect that support ring block is arranged is the connection of thread that the radial forces that male connection internal threads joint is produced fully is postponed to male connection and female adapter, the axial load power of dispersion male connection and female adapter, adds the stability that male connection is connected with female adapter.
7. sealing ring is set in detent, adds the sealing between male connection and female adapter.
