Specific embodiment
With reference to Fig. 1, Quick unhooking device laid by submerged pipeline, including multiple pipe clamps being fixedly connected with floating drum 1.I.e. floating drum
It is uniformly arranged multiple pipe clamps on 1.
As Fig. 2, pipe clamp includes the first pipe clamp 2 and second pipe clamp 3 of half arc, one of the first pipe clamp 2 and the second pipe clamp 3
Connection ring 4 is respectively equipped with connection end, is provided with connecting pin 5 in connection ring 4.Can be by the first pipe clamp 2 and by connecting pin 5
One end phase of two pipe clamps 3 is fixed.
Another connection end of the first pipe clamp 2 and the second pipe clamp 3 is respectively perpendicular and is provided with connection bump 6, and connection bump 6 is all provided with
There is connecting hole 7, all running through in connecting hole 7 has connecting rope 8, two connecting ropes 8 of the first pipe clamp 2 and the second pipe clamp 3 end are led to
Cross euphroe 9 to link together.Can by the other end of the first pipe clamp 2 and the second pipe clamp 3 even by connecting rope 8 and euphroe 9
Connect fixation.
The steel wire rope 10 being connected with hoist engine is provided with connecting pin 5.Steel wire rope is pulled by hoist engine, can be with steel wire rope
Quickly move, thus connecting pin 5 is pulled out in connection ring 4, mobile 21 meters about it is possible to complete the laying of 600 mitrons；Oil
After pipe sinks, withdraw steel wire rope, withdraw floating drum 1 simultaneously, operation can complete.
Be provided between connecting pin 5 and connection ring 4 for prevent connecting pin 5 be disconnected ring 4 band 11.By pricking
Band 11 can prevent rustless steel connecting pin 5 from voluntarily breaking off relations in the case of accident it is ensured that sea pipe does not occur in transit voluntarily to take off
The marine situation of hook landing.
The binding nose 12 being fixedly connected with floating drum 1 is arranged with the first pipe clamp 2.By connecting steel in binding nose 12
Cord can be fixedly connected with floating drum 1.
It is provided with buffering braiding layer 13 in pipe clamp inner surface.By buffering braiding layer 13, extra large pipe surface can be played with buffer protection work
With.
Operation principle:
Complete being fixedly connected of pipe clamp and floating drum 1 first.This utility model can be as needed uniform 4 or 6 on floating drum 1
Individual pipe clamp, and be fixedly connected with binding nose 12 on pipe clamp with iron chains or stainless steel wire rope.
Operating process: under oil pipe during water, floating drum 1 is hung to above oil pipe and (contacts), pipe clamp is just in the oil naturally drooping
Pipe both sides, is first plugged connecting pin 5, and ties band 11, more quickly tightens connecting rope 8 with euphroe 9；Second floating drum hangs
To be the distance setting with first floating drum when putting, connect pipe clamp with same method, so constantly repeat；Under oil pipe is continuous
Water, the steel wire rope 10 connecting connecting pin 5, also with lower water, so descends water operation to complete；After the position of oil pipe determines, need the company of pulling out
During pin 5, provide signal, little hoist engine starts, under the pulling force of hoist engine, steel wire rope 10 quickly moves steel wire rope 10, mobile
21 meters about it is possible to complete the laying of 600 mitrons；After oil pipe sinks, withdraw steel wire rope 10, withdraw floating drum 1, operation is complete simultaneously
Become.
This utility model is connected using euphroe 9 and connecting pin 5, tight rope, and 9 realize quick clamping, and connecting pin 5 can be realized
Overall pull-off, the quick clamping of energy and rapid unhooking, improve working performance；Whole pipe clamp is fixed together with floating drum 1, connecting pin 5
Float with floating drum 1 after pulling out support, pipe clamp can be reused, reduce and waste；Because pipe clamp is not left on oil pipe, for subsequently digging
Ditch provides convenient；Using quick band 11, during can preventing from laying extra large pipe, connecting pin 5 is when stormy waves or other carelessly touch
Naturally the problem disengaging；Connecting pin 5 on same floating drum is deviate from simultaneously, and the connecting pin on adjacent floating drum can a little later 1 point take off
Go out, it is less to realize dynamics of pulling pin, and unhook order is to start to break off relations from one end of extra large pipe, solve extra large pipe positioning of sinking inaccurate
Really, the problem easily occurring to deviate with original route.The extra large pipe of submerged pipeline laying Quick unhooking device minimizing ties up and sea pipe is de-
Hook program, effectively saves that land is prefabricated and the offshore construction time, guarantees pipe laying construction precision simultaneously, reduces and adjust work under water
Measure, it is to avoid potential safety hazard.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess,
Can also make a variety of changes on the premise of without departing from this utility model objective, the content after change still falls within this utility model
Protection domain.
