Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, structure of the present utility model is, comprise the top connection 2 and lower contact 6 that are socketed in correspondence with each other, top connection 2 and upper tube body 1 weld together, composition top riser pipe is single, lower contact 6 and lower tube body 7 weld together, and composition bottom riser pipe is single, and the contact surface of top connection 2 and lower contact 6 is provided with sealing ring 3;
With reference to Fig. 2, Fig. 3, top connection 2, lower contact 6 socket place periphery respectively correspondence are provided with annular groove, lower annular groove, when top connection 2 and lower contact 6 are socketed tight, upper annular groove and lower annular groove to be jointly provided with in C type jump ring 5, C type jump ring 5 circumferentially radial direction and to be provided with multiple driving bolt 4.
With reference to Fig. 4, Fig. 5, top connection 2 lower end edge inner surface circumferentially establishes spaced boss 8, lower contact 6 upper end edge circumference establishes spaced groove 9, the boss 8 of top connection 2 and groove 9 size of lower contact 6 can be engaged in correspondence with each other, after top connection 2 is reliably docked with lower contact 6, boss 8 and the occlusion of groove 9 correspondence closely cooperate, and can limit the single circumference in riser pipe upper and lower part and rotate.
Reference Fig. 6, C type jump ring 5 is the annular element of opening, is convenient to disassembling, assembling and replacing.
Be arranged on the outside of top connection 2 and lower contact 6 with reference to Fig. 7, C type jump ring 5, circumferentially radial direction has multiple screw, is separately installed with one and drives bolt 4 in each screw.
Installation process of the present utility model is,
As Fig. 1, be first fixed on platform by single for the bottom riser pipe welded;
Then, be arranged on by C type jump ring 5 in the single top connection of top riser pipe 2 in annular groove, rely on the weight that top riser pipe is single, in C type jump ring 5 bottom, inclined-plane slowly contacts with the outer inclined-plane of lower contact 6, sees the left figure of Fig. 2; Drive C type jump ring 5 radially outward to move, until C type jump ring 5 contacts with the bottom straight section of lower contact 6, C type jump ring 5 no longer radially outward movement is shown in Fig. 2 and schemes; Top connection 2 continues to move downward under the effect of deadweight, top connection 2 upper boss starts to have contacted guiding with the lower recess of lower contact 6 corresponding matching, when the straight section height of lower contact 6 is more than in C type jump ring 5 bottom during bevel altitude, top connection 2 boss 8 coordinates complete with lower contact 6 groove 9, C type jump ring 5 lower end enters in the lower annular groove of lower contact 6, C type jump ring 5 affranchises state, namely locks that upper and lower part riser pipe is single sees the right figure of Fig. 2.
Circulate successively, by this connector can realize fast riser pipe single and single between be connected bunchiness.
Unloading process of the present utility model is,
When dismantling riser pipe and needing to unlock, rotary actuation bolt 4, drives C type jump ring 5 radially outward to move, promotes top marine riser single, can realize unlocking that upper and lower part marine riser is single sees Fig. 3.
In a word, device of the present utility model, utilizes closely cooperating of top connection 2 upper boss and lower contact 6 lower recess, and the single circumference in restriction riser pipe upper and lower part is rotated, and improve torque resistant performance, sealing effectiveness is effectively ensured; C type jump ring 5 is arranged on the outside of top connection 2 and lower contact 6, makes jump ring carry evenly, simple to operate, time saving and energy saving; This connector can realize C type jump ring 5 under riser pipe Gravitative Loads, and to lock upper and lower part riser pipe single, do not need special tool; During unblock, rotary actuation bolt 4, drives C type jump ring 5 radially outward to move, promotes top marine riser single, can realize unlocking upper and lower part riser pipe single.
