The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
As shown in Figure 1; The quick riser connector of isometrical self-centering formula of the present invention; Comprise male joint 1, lock dog 5, chuck 6, bevel gear 8, female joint 10; Male joint 1 wherein and female joint 10 are welded on marine riser main pipe's two ends (marine riser is in turn connected into string through the male and female joint between single and single during the duty assembling for marine riser one an end welding female joint 10, other end welding male joint 1) respectively; All offer six corresponding auxiliary line holes on male joint 1 and female joint 10 disk borders; Evenly be provided with six cavitys at female joint 10 upper edge circumference, each cavity structure inside is equipped with a bevel gear 8, whole chuck 6 and a lock dog 5 from top to bottom successively, and each bevel gear 8 is fixedly connected with female joint 10 through a positioning bolt 9 respectively; After male joint 1 is plugged into female joint 10 extreme positions; The primary seal 7 that is provided with between male joint 1 and the female joint 10 plays the effect of insulating sea water and drilling fluid, and lock dog 5 snaps in the surperficial cannelure 17 of male joint 1, realizes firm tight connection.
Chuck 6 soffits are provided with bevel gear 8; Upper surface is provided with plane Archimedes's screw thread; Utilize the property advanced such as grade of Archimedes spiral direction in utmost point footpath, when chuck 6 rotations, make six lock dogs 5 in female joint 10 cavitys with identical displacement near or away from male joint 1; Reach the purpose of self-centering and self-locking, make that six lock dogs 5 contact with cannelure 17 in the male joint 1 more fully, reliable.Plane Archimedes's screw thread on chuck 6 tops can only through bevel gear 8 drive chucks 6 rotate realize lock dogs 5 and male joint 1 near or away from, otherwise 5 of lock dogs can not make chuck 6 rotate.
Multiple shapes such as that lock dog 5 and cannelure 17 in the male joint 1 are set to as required is trapezoidal partially, trapezoidal, rectangle, triangle.
With reference to Fig. 1, Fig. 2; When locking is installed; Earlier female joint 10 is fixed on the platform; After male joint 1 is plugged into female joint 10 extreme positions, the male joint of each auxiliary line (choke flow line 11, hydraulic line I12, mud supercharging pipeline 13, kill line 14, hydraulic line II15) is inserted in the corresponding female joint; Then through pneumatic impact spanner or other instruments any bevel gear 8 that turns clockwise; Thereby bevel gear 8 drives chuck 6 rotations with the bevel gear engaged transmission of chuck 6 soffits; Plane Archimedes's screw thread of chuck 6 upper surfaces drives six lock dogs 5 simultaneously; Make six lock dogs 5 move along utmost point footpath direction equidistant inward (entad) at the interior of female joint 10, in the cannelure 17 that inserts male joint 1 external surface, thus the quick connection and the installation of realization male and female joint.Plane Archimedes's screw thread of chuck 6 upper surfaces is realized self-locking, promptly can only through bevel gear 8 drive chucks 6 rotate realize lock dogs 5 and male joint 1 near, otherwise then not all right; The load that marine riser is installed on the lock dog 5 of back can not pass to chuck 6 and bevel gear 8, can only pass to female joint 10.
Like Fig. 3; When needing release (male and female splice failure); Be rotated counterclockwise any bevel gear 8, thereby the bevel gear engaged transmission of bevel gear 8 and chuck 6 bottoms drives chuck 6 rotations, plane Archimedes's screw thread of chuck 6 upper surfaces drives six lock dogs 5 simultaneously, and equidistant the moving outward of direction moves on to the release extreme position up to lock dog 5 along utmost point footpath in the I-shaped groove of female joint 10; Break away from cannelure 17; Propose male joint 1 then, can the male and female joint be separated, thus the quick release and the disengagement of realization male and female joint.
