Including lift it is floating refute and lifting device, the lift is floating refute and set there are two, floating refute of lift swims on the water surface, two lifts are floating refute between be arranged
Steel wire is lifted by crane, the both ends for lifting by crane steel wire are connect with anchor head respectively, and anchor head is arranged on the inside of the floating deck for refuting top of lift, lifting device
It is connect with anchor head by steel wire.
Preferably, further include guide roller, the guide roller setting is between lift floats and refutes and lift by crane steel wire.
Preferably, the intermediate position of the lifting steel wire connects backing girder steel, and backing girder steel, which is placed on, to salvage a sunken ship
Hull bottom.
Preferably, the lifting device includes lift cylinder, accumulator, cushion cylinder, and the lift cylinder is entire system
System provides lifting force, and accumulator is connect with cushion cylinder, and accumulator provides buffering energy, cushion cylinder and promotion for cushion cylinder
The front and back connection of oil cylinder.
Using the technical solution of the utility model, advantageous effect below can be obtained：
The large-tonnage synchronization lifting system of the utility model can adapt to the lifting that center of gravity does not know large structure, energy
It is enough to reduce marine stormy waves stream and cause the lifting increased influence of load, compared to the crane capacity that Large marine crane barge has bigger,
More hoist cables can be set in lifting operation, reduce the risk of suspended object structural failure.
Description of the drawings
Brief description is made to the content expressed by each attached drawing of this specification and the label in figure below：
Fig. 1 is the structural schematic diagram of this synchronization lifting system；
Fig. 2 is the partial enlarged view of lifting device in Fig. 1；
Label in above-mentioned figure is：1, lift is floating refutes；2, steel wire is lifted by crane；3, guide roller；4, anchor head；5, steel wire；6、
Accumulator；7, cushion cylinder；8, lift cylinder；9, backing girder steel；10, shipwreck.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, for example involved to specific embodiment of the present utility model
Mutual alignment and connection relation, the effect of each section and operation principle between the shape of each component, construction, each section etc. make into
The detailed description of one step.
As shown in Figure 1, this large-tonnage synchronization lifting system, which includes that lift is floating, refutes 1 and lifting device, lift is floating refute 1 set there are two,
Lift is floating to refute 1 and swims on the water surface, two lifts are floating refute 1 between setting lifting steel wire 2, the both ends for lifting by crane steel wire 2 connect with anchor head 4 respectively
Connect, anchor head 4 be arranged lift it is floating refute 1 top, lifting device connect by steel wire 5 with anchor head 4.Further include guide roller 3, leads
The setting of way roller 3 is floated in lift and is refuted between 1 and lifting steel wire 2, the intermediate position connection backing girder steel 9 of lifting steel wire 2, backing girder steel
9 be placed on need to salvage a sunken ship 10 hull bottom.
As shown in Fig. 2, lifting device includes accumulator 6, cushion cylinder 7 and lift cylinder 8, lift cylinder 8 is entire system
System provides lifting force, and accumulator 6 is connect with cushion cylinder 7, and accumulator 6 is that cushion cylinder 7 provides buffering energy, cushion cylinder 7
With lift cylinder 8 is front and back connect, control lift cylinder 8, the effect drive of lift cylinder 8 by controlling cushion cylinder 7 when use
Steel wire 5 promotes shipwreck, and the setting of cushion cylinder 7 can reduce the load generated due to wind wave flow action in offshore lifting operation
Lotus increases sharply, and reduces integral hoisting load.It can more uniformly be distributed the load of all hoist cables simultaneously, to which effectively control is hung
Pretend often to cover the maximum load of lifting system in industry.
In use, according to suspended object estimate weight, center of gravity determines the specification and quantity of lifting device.According to suspended object
Hoisting depth determines the floating beam refuted of the lift chosen.The arrangement that steel wire is lifted by crane according to the size of suspended object and structure determination, to
Determine that lifting device lifts the arrangement above floating barge at two.According to the arrangement of lifting device and design load carry out lift it is floating refute it is whole
Body and local strength check；The structure design of lifting device connects bearing；Lift by crane the structure of guide roller 3 at 2 upper deck of steel wire
Design.Mooring system design is carried out according to the sea conditions in construction marine site, determines windlass and corollary equipment that barge installs additional
Arrangement.According to the sea conditions and buffer requirements in construction marine site, buffer system is designed.
As shown in Figure 1, being loaded onto ship according to the equipment that the layout of equipment of design completes two barges；Lifting system carries out group
Dress, land examination are drawn；Dullness finally is carried out to lifting system, is even adjusted.Then floating refute of two lifts is dragged to construction site by tugboat, pressed
Barge, which is floated, according to two lifts of design anchor position figure pair carries out cloth field of casting anchor.
Diver, which dives under water, completes the installation of lifting steel wire 2, carries scheme according to the tune of formulation, lash is adjusted to reach appearance before promotion
State carries out 30% load before formal promoted to promoting rigging substep, completes all preloads for promoting rigging.It is pressed when formal promotion
Load is synchronized according to 50%, 60%, 80%, 90%, 100% design load.To close to before and after 100% load, partial dot starts to continue
Rise, partial dot is still motionless, continues load 105% to these motionless points, 110%, 115%, until suspended object start it is whole from
It opens sea bed, confirms suspended object aweigh enough after distance, accumulator 6 is carried out oil-filled, cushion cylinder 7 starts to act on, this
It keeps load to synchronize promotion afterwards, the state of cushion cylinder 7 is monitored in lifting process, keep the piston of cushion cylinder 7
Bar is close at the stroke of half.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
