Preferably, described main body 21Hai Qi both sides are provided with the dash receiver 26 of described erecting tools 100, so that the support to erecting tools 100 to be provided.The setting position of dash receiver 26 is defined as: when erecting tools 100 and connector 200 complete behind location, dash receiver be able to provide the support of the erecting tools locked hydraulic cylinder matching with flange 223, as shown in Figure 3.
Preferably, described main body 21 docking section 22 is provided with conical surface retaining mechanism 27 on this sleeve part 221, when the direction that Dang Gai promotion part 222 connects hub seat 300 to described manifold shifts out sleeve part 221, this conical surface retaining mechanism 27 can lock the relative position of this promotion part 222 and this sleeve part 221.Wherein, described conical surface retaining mechanism 27 has a square cone and a lock bolt, square Zhui one end is resisted against on this promotion part 222, and lock bolt is by screwing in sleeve part 221 by its locking, after preventing that manifold butt-joint operation from finishing, because becoming flexible and claw 23 locking inefficacies the promotion part 222 that accidental shock load causes.
Preferably, both sides, described housing 25 top have lifting rope shackle 254.While transferring this connector 200 by ，Dang Xiang deep-sea, lifting rope shackle 254 position is rationally set, the connector being suspended in midair by lifting rope can be transferred with attitude more stably.
Below in conjunction with accompanying drawing 3 and 4 in detail, method of operating of the present invention is described in detail:
1. transfer connector and locate with hub seat
First by lifting rope, transfer hub seat 300 tops in connector 200Zhi seabed, two leads 241 of device 200 to be connected enter into respectively two gathering sills 32 of hub seat 300 accordingly, continue to transfer connector 200, until two locating cones 242 of connector 200 bottoms are limited to respectively in two locating cone grooves 33 of hub seat 300, complete the location of connector 200 and hub seat.
2. remove the locking of connector
ROV(underwater robot) untie lifting rope, regained sea; Then ROV removes the locking cap 253 on connector 200 tops, and is recovered in work basket, and now the main body 21 of connector 200 and housing 25 unlock, and main body 21 enters the state of preparing docking; Last ROV is used secondary locking instrument to remove the locking of connector 200 docking section 22.
3. transfer erecting tools and locate with connector and hub seat
First recover erecting tools to initial position, ROV takes out erecting tools 100 and is placed on connector 200 and hub seat 300 tops from work basket, by adjustment, dock hydraulic cylinder 13 afterwards and the first guide sleeve 151 of erecting tools 100 is aimed to the guide pile 34 of hub seat 300, the guiding stake 212 of the second guide sleeve 152 alignment connectors 200 is inserted in respectively chimeric, to complete the location of erecting tools, last ROV discharges erecting tools 100, and two locked hydraulic cylinders 14 of erecting tools 100 together glide along the slide block that docks hydraulic cylinder leg 12 two ends by slide rail because of Action of Gravity Field together with portal frame 11, until two locked hydraulic cylinders 14 of erecting tools 100 slide to down respectively the dash receiver 26 of connector 200, now the locking actuator 141 of locked hydraulic cylinder 14 terminations be able to be stuck on the flange 223 of connector 200 docking section 22.The state that completes erecting tools, connector and hub seat location is shown in Figure 3.
4. connector and the docking of hub seat
First start docking hydraulic cylinder 13 and carry out the contraction of cylinder bar 131, because hub Zuo300 fixes one end, so docking hydraulic cylinder 13 can be shifted to hub seat 300 with erecting tools 100 integral body, again because the second guide sleeve 152 fit guiding stakes 212, make the main body 21 of connector 200 also together with the housing 25 that is drawn out connector, and move to hub seat 300 along the direction of rail groove 251, until the female wheel hub face of claw 23 and the male wheel hub face of hub seat 300 engage; Start afterwards a pair of locked hydraulic cylinder 14 and carry out the release of cylinder bar, the locking actuator 141 of cylinder masthead end can be released in the sleeve part 221 of 222Cong docking section, connector 200 promotion part 22, completes claw 23 and locks with the male wheel hub 31 of hub seat 300.The state having docked refers to Fig. 4.
5. use ROV to regain erecting tools
ROV catches the portal frame 11 of erecting tools 100, because now each guide sleeve also in the fixing state of each combination, so first the portal frame 11 of erecting tools can be raised along slide rail, make locked hydraulic cylinder 14 depart from the dash receiver 26 of connector 200, lock actuator 141 simultaneously and depart from flange 223; When the slide rail bottom row of portal frame 11 is during to support 12 slide position, each guide sleeve 151,152 of docking hydraulic cylinder 13 departs from respectively guide pile 34 and guiding stake 212, completes the disengaging completely of erecting tools, then erecting tools is recovered in work basket.
6. docking section locking
Use ROV that lock bolt is locked to sleeve part 221, fixedly the relative position of promotion part 222 and sleeve part 221.So far deep water manifold abutting joint is complete, can be carried out by ROV the subsequent steps such as sealing test.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, the common variation that those skilled in the art carries out within the scope of technical solution of the present invention and replacement all should be included in protection scope of the present invention.
