But the research meanses such as present theory or numerical method can not well carry out mechanical analysis to such labyrinth, so experiment becomes the Main Means of umbilical cables research.If the linkage function of umbilical cables experiment joint does not reach requirement, can directly have influence on the accuracy of experimental result even make cable test specimen failure, therefore the research of umbilical cables experiment joint had very important significance.For obtaining correct experimental result, to containing the umbilical cables of double armor structure of steel wire, keep the synchronous force and deformation of two-layer steel wire particularly important during experiment.There is series of problems in the experiment of existing umbilical cables with joint: steel wire of internal layer fixedly be by the snap-in force between the flange, when umbilical cables is stretched, pulling force can act on the kingbolt that snap-in force is provided, when kingbolt generation elongation strain and then when losing snap-in force to flange, steel wire of internal layer just can not get due fixing.
Summary of the invention
Goal of the invention: for the problems referred to above, provide a kind of umbilical cable for underwater production system experiment joint, it can make umbilical cables bear 10 tons with upper pulling force in the inside and outside two-layer steel wire in assurance end still be in and effectively be held state.
The technical scheme that adopts: provide the umbilical cable for underwater production system experiment to use joint, having comprised: external stability flange connection group, inner clamp device; External flanges connection group further comprises: lower cone flange 1, middle cone flange 4, large flange 6; Be fixed with bolt 12 between the above-mentioned three, and large flange 6 all reserves the certain interval Δ with surperficial joint place, the middle cone flange 4 of middle cone flange 4 with the surperficial joint place of lower cone flange 1, can form certain initial snap-in force to armouring wire after guaranteeing to install; The top of large flange 6 is provided with the through hole 11 that is connected with experimental provision in the circumferential direction of the circle; Inner clamp device further comprises: conical cover of wedge, baffle ring 3, the upper and lower surface of conical cover of wedge is circular arc and outside surface embossing, be divided into cover of wedge 5 and lower cover of wedge 2, match with middle cone flange 4 in upper cover of wedge 5 outer rings, match with lower cone flange 1 in lower cover of wedge 2 outer rings, apply pulling force larger in experimentation, cover of wedge contacts with the cone flange that more compaction forces is larger, friction self-locking outer to realize, interior two-layer armouring wire; And upper cover of wedge 5 is enclosed within respectively the armouring wire outside surface with lower cover of wedge 2, and middle umbilical cables oversheath 10 all divests; In the friction force of the outer ring of cover of wedge embossing with increase internal layer armouring wire 7, outer armouring wire 8; Middle baffle ring 3 is arranged between cover of wedge 5 and the lower cover of wedge 2, is used for realizing when mounted with the preliminary compression of cover of wedge with the cone flange.
Beneficial effect: the utility model adopts two covers of wedge to cooperate the friction self-locking of realizing inside and outside two-layer steel wire with two cone flanges respectively, can guarantee that inside and outside the experiment pulling force effect lower sub more than 10 tons two-layer steel wire still can be fully clamped and do not produce slip.Simultaneously, the utility model has reference for extra large cable rig-site utilization joint, because the rig-site utilization joint is subjected to the alternate load effect of wave, stream, cause bolt looseness, than the method that by bolt two parts is compressed to provide armouring wire fixing, the utility model adopts the method for cover of wedge friction self-locking principle then can better adapt to on-the-spot alternation and extreme value load action.
