Description

Joint for riser pipe
Technical field
The utility model relates to a kind of joint, particularly about a kind of joint for riser pipe.
Background technology
In offshore drilling process, riser pipe one of the important drilling equipment that is absolutely necessary, conventionally adopt conventional threaded joint or snap joint that some riser pipes are linked in sequence into a riser pipe combination, then from offshore drilling platform to sea-bottom shallow, for drillng operation provides passage.Although adopt conventional threaded joint or snap joint to be easy to realize, cost is also lower, but has the critical defects such as whole bending resistance, anti-ice performance weakness because of junction strength deficiency.In practical engineering application, often there is joint and destroy prior to riser pipe, thereby cause tremendous economic loss and work accident etc.Improve the intensity between riser pipe, thereby improve the whole flexing resistance of riser pipe combination, finally improving its anti-ice is current assistant officer problem to be solved.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of joint for riser pipe that strengthens riser pipe junction intensity, improves riser pipe composite entity flexing resistance and anti-ice.
For achieving the above object, the utility model is taked following technical scheme: a kind of joint for riser pipe, it is characterized in that, it comprises a male joint and and the female joint that removably connect coaxial with described male joint, wherein, described male joint comprises cylindrical first housing of a both ends open, and some edges are circumferentially fastenedly connected the first wing plate on described the first housing outer wall; Described female joint comprises the second housing that an internal diameter, external diameter all equate with described the first housing, and some edges are circumferentially fastenedly connected on described the second housing outer wall and can with the second wing plate that described in each, the first wing plate face contacts; The front of motor of described the first housing and the second housing all reserved clamping device is used position.
Described male joint and female joint spin with the internal thread that is arranged on described the second housing link by being arranged on the external screw thread of described the first housing link.
Circumferential uniform six described first wing plates at described the first housing outer wall middle part, the equal half wedge-like structure for being processed by variable cross-section i iron of the first wing plate described in each.
The equal chamfer trapezoidal shape structure for being processed by i iron of the second wing plate described in each.
The utility model is owing to taking above technical scheme, it has the following advantages: the housing outer wall of 1, the utility model male joint, female joint is circumferentially all equidistantly fastenedly connected some i iron wing plates that quantity equates, because i iron wing plate itself has good second moment of area characteristic, therefore can greatly improve the anti-bending strength of male joint and female joint itself.2, together with the utility model is threaded connection male joint is screwed in female joint, after spinning, the inner surface of the wing plate of the external surface laminating female joint of the wing plate of male joint, face contact between the two, strengthened the bending resistance moment of inertia of joint area, do not need additional any operation just can improve the bending resistance of joint area, in use, the internal face of each layer of tubing string during the utility model combines with riser pipe contacts, and then greatly strengthen the whole anti-bending strength of riser pipe combination, simultaneously, wing plate is also between each layer of tubing string, and the spoke effect of playing power transmission between each layer of tubing string and outermost riser pipe, greatly promoted the anti-ice ability of riser pipe composite entity.3, due to two ends of the present utility model respectively with riser pipe combination in the two ends welding of sleeve body, therefore simple to operation, intensity is high.4, simple and reasonable, easy to use, long service life of the present utility model, can be used for the connection of each layer of sleeve pipe in riser pipe combination, when not affecting normally the carrying out of drillng operation, also has the scope of application very widely.

Fig. 2 is the overall structure schematic diagram of the utility model male joint
Fig. 3 is the overall structure schematic diagram of the utility model female joint
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises a male joint 1 and a female joint 2 being connected with male joint 1 coaxial threaded.
As Fig. 2, male joint 1 comprises the cylindrical housings 10 of a both ends open, one end of housing 10 arranges one section of external screw thread 11, the outer wall middle part of housing 10, along it, be circumferentially equidistantly fastenedly connected six wing plates 12, the half wedge-like structure of wing plate 12 for being processed by variable cross-section i iron, the reserved clamping device of the other end of housing 10 is used position.
As shown in Figure 3, female joint body 2 comprises that an internal diameter, external diameter all equate housing 20 with housing 10, housing 20 one end inwalls are offered one section of internal thread 21 spinning with external screw thread 11, the outer wall of housing 20 one end, along it, be circumferentially equidistantly fastenedly connected six wing plates 22, the chamfer trapezoidal shape structure of wing plate 22 for being processed by i iron, the reserved clamping device of outer wall of the other end of housing 20 is used position.
Describe using method of the present utility model below in detail:
As shown in Figure 1, while using the utility model, the male end of male joint 1 is aimed at the female end of female joint 2, then both are tightened, in rundown process, fit the gradually on-right angle waist of wing plate 22 of the wedge surface of each wing plate 12, until external screw thread 11 is all fitted with wing plate 22 with internal thread 21 and wing plate 12.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode and manufacture craft 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.
