The standpipe of conveyance conduit and platform is linked together with form of flanges, since underwater welding technology is immature, usually vertical
Rotary flange is set, and prefabricated on platform structure, pipeline is rear in place to connect with riser flange by pulling into water on pipe.
The conventional device of pipeline drawing is: production is a set of using blank flange as front end, and rear portion is welded with insertion ear mount plate weldering
It is connected in integrated cutting back seamless steel pipe, bolt is easy for installation when in order to connect with underwater flange.In use, by by blind plate method
Blue connect after underwater drawing to predetermined position with pipe end flange using more bolt is needed disassembling bolts, whole mistakes
The operating time of journey is long, and difficulty is larger, and bolt also is easy to fall under water to lose.In addition, the structure weight of the conventional equipment
Measure larger, diver is difficult to move under water, further increases underwater work difficulty.
This patent exactly proposes a kind of quick towed equipment of submerged pipeline construction in this context.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of quick towed equipments of submerged pipeline construction.
The present invention is realized by the following technical solutions:
A kind of submerged pipeline is constructed quick towed equipment, including device noumenon, towing tension along plate, Top fastening screw, swing claw and
Removable pin shaft, described device ontology are the class triangular structures as made of one piece of steel plate cutting processing, and triangle shaped ends are open-minded
Mouth structure, the top and bottom at gap both ends are welded with ear mount, weld after the device noumenon aperture near gap in top concentric position
It is connected to nut；The towing tension is aperture otic placode form along plate, and lower end is welded as a whole with described device ontology；The Top fastening screw
The screw of lateral small through hole is provided with for a radicle, the other end is the polished rod that a bit of diameter is less than diameter of thread, described to hold out against
Screw can be attached with the nut on described device ontology；The swing claw passes through the removable pin shaft and described device
The ear mount of ontology is attached and fixes.
The structure of the removable pin shaft is similar to there is the bolt pattern of polished rod, only also small with aerofoil profile on screw rod
Piece, nut are wing nut, convenient for installing and freeing manually.
The polished end of the Top fastening screw connects protection copper sheathing by interference, can avoid Top fastening screw in contact underwater flange
When scratch flange surface, influence sealing effect.
The towing tension can reinforce connection with gusset along plate and described device ontology and fix.
Beneficial effects of the present invention: the present invention provides a kind of quick towed equipments of submerged pipeline construction, can be effective
Reduction install operation difficulty, free under water conveniently, the flange of feed-line can quickly be drawn to installation in place, after making
Continuous flange mating operation is convenient and efficient, greatly improves construction efficiency, shortens the operating time, creates preferable economic benefit.
The present invention will be further described with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is a kind of quick towed equipment connection schematic diagram of submerged pipeline construction；
Fig. 2 is a kind of quick towed equipment axonometric drawing of submerged pipeline construction；
Wherein: 1- pipeline；2- underwater flange；3- flange draws Quick Connect Kit；3.1- towing tension is along plate；3.2- device noumenon；
3.3- Top fastening screw；3.4- swings claw；3.5- protects copper sheathing；3.6- sealing ring sheath；The removable pin shaft of 3.7-.
Specific embodiment
With reference to the accompanying drawing 1 and attached drawing 2, the present invention is described in detail.
A kind of submerged pipeline construction draws Quick Connect Kit 3 with flange, including device noumenon 3.2, towing tension along plate 3.1,
Top fastening screw 3.3, swing claw 3.4 and removable pin shaft 3.7, described device ontology 3.2 are base of all component groups to installation
Plinth, the class triangular structure as made of one piece of steel plate cutting processing, triangle shaped ends are gap structure, the top and bottom at gap both ends
It is welded with ear mount, is welded with nut in top concentric position after the device noumenon aperture near gap；The towing tension is along plate 3.1
It is attached transmitting traction force for the shackle in aperture otic placode form, with drawing wirerope, lower end and described device ontology 3.2 weld
It is connected in one；The Top fastening screw 3.3 is that a radicle is provided with the screw of lateral small through hole, when use by iron rod or it is other just
Property strong rotation, can hold out against or unclamp screw, the other end is the polished rod that a bit of diameter is less than diameter of thread, is connected by interference
Copper sheathing 3.5 is protected, Top fastening screw is can avoid and scratches flange surface when contacting underwater flange, influence sealing effect, it is described to hold out against
Screw 3.3 can be attached with the nut on described device ontology 3.2；The swing claw 3.4 passes through the removable pin shaft
3.7 are attached and fix with the ear mount of described device ontology 3.2.
At sea construction in, flange draw Quick Connect Kit 3 be a set of purely mechanic device, by loop wheel machine lift to
Install near 2 end of underwater flange, by removable pin shaft 3.7(backwards to towing tension along the side of plate 3.1) it releases, make to swing claw
3.4 can swing, in order to prevent will during dilatory installation is in place in the end of Top fastening screw 3.3 installation protection copper sheathing 3.5
The sealing ring being mounted on underwater flange scratches, and sealing ring sheath 3.6 is placed between Top fastening screw 3.3 and underwater flange 2, so
Claw 3.4 will be swung afterwards and blocks underwater flange 2, by removable pin shaft 3.7(backwards to towing tension along 3.1 side of plate) insertion otic placode, connection
Wing nut locks pin shaft, and later by constantly rotating, Top fastening screw 3.3 makes the 3.5 push pipe line of protection copper sheathing of its end
The surface of flange 2 continues to turn Top fastening screw 3.3, its pressure is made to reach the requirement of design installation.Finally by steel cord ends
Shackle and towing tension connected along plate, installation can be completed and enter the preparation before water.
It pipeline 1 is entered water draws to loosen the drawing of wirerope to riser flange attachment, make wirerope not by active pulling force.
Later, diver unscrews Top fastening screw 3.3 in place, by removable pin shaft 3.7(backwards to towing tension along 3.1 side of plate) it releases, smoothly
It unclamps and swings claw 3.4, make its swing, flange can thus be drawn to Quick Connect Kit 3 and underwater flange 2 directly divides
It opens.Flange is drawn Quick Connect Kit 3 finally by recycling wirerope to recycle, convenient for installing and using next time.Subsequent pipe
Connection between collimation method orchid, is not related in this section, details are not described herein.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
