The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model device is, the two ends that are included in marine riser are connected with male joint 1 and female joint 2 respectively, marine riser is in turn connected into string by the male and female joint between single and single during use, below narrates with female joint 2 ways of connecting from the top down with male joint 1.
With reference to Fig. 1, Fig. 2, female joint 2 termination inner chambers are provided with eight groups of adjustment units and four groups of positioning units along the circumference axially spaced-apart.Female joint 2 internal circular surfaces and male joint 1 contact surface also are provided with sealing ring 10, are used for the annular space between closure tolerance joint 1, the female joint 2, in case the outside leakage pollution of inner mud ocean in the work.
With reference to Fig. 1, Fig. 3, male joint 1 epimere (revealed section) maximum outside diameter circumferentially is provided with four grooves and four boss, and four grooves are used to guarantee the installing space of eight groups of adjustment units, and four boss are used to bow and press four groups of positioning units; Male joint 1 hypomere (interpolation section) largest circumference external surface is provided with annular groove 11, is used for locking with lock dog 3.
With reference to Fig. 2, Fig. 4, every group of adjustment unit comprise lock dog 3, drive block 4, location-plate 5, on drive bolt 6, drive bolt 8 down, wherein, last driving bolt 6, drive bolt 8 along coaxial being oppositely arranged in female joint 2 terminations down, being provided with between last driving bolt 6 and the following driving bolt 8 can be along female joint 2 axially movable drive block 4, the side of drive block 4 towards female joint 2 axle center is provided with the lock dog 3 that can move radially along female joint 2, the below of lock dog 3 is provided with location-plate 5, and lock dog 3 is realized supporting and axial location by location-plate 5.
With reference to Fig. 2, Fig. 4, Fig. 5, every group of positioning unit comprises back-moving spring 7 and positioning bolt 9, back-moving spring 7 is sleeved on the positioning bolt 9, the two ends wire spring of back-moving spring 7 is installed in respectively in the trough in the adjacent lock dog 3, each back-moving spring 7 can be controlled two adjacent lock dogs 3, realize that under the effect of elastic force lock dog 3 is the outside Unscrew of axis with positioning bolt 9, deviate from annular groove 11, realize unblanking of male joint 1, female joint 2.
