Description
Technical field
It is quick, quasi- the present invention relates to being carried out when the construction of the liquefied gas carrier of shipbuilding, especially c-type independent tank formula to flow container
Really lifting guiding and the method for positioning.
Background technique
LNG carrier is mainly the storage and transport that natural gas is carried out by flow container, and relatively common liquefaction day
Right gas ship is the LNG carrier with c-type independent tank formula.Needing the LNG carrier built at present is that storage volume is super
Cross 10000 cubes of large-scale flow container.On LNG carrier, in order to guarantee stability and safety, flow container and bulkhead gap
It is very small, but the quality of flow container itself is but very big.In building course, also the relevant lifting work of flow container is mostly enterprising in river surface
Row, any small trend fluctuation or heaving of the sea can all cause the fluctuation of crane barge and construction ship, extreme influence flow container is just
It is really in place.It, must before lifting in order to guarantee the accurate in place of flow container and flow container external insulation layer and stainless steel sheet| be protected not to be broken
Corresponding lifting guide-localization guide must be established.
Currently, shipyard is to there are two types of the tank installation localization methods of the liquefied gas carrier of c-type independent tank formula both at home and abroad, one is draws
Line ocular estimate, by wirerope bolt on the guiding otic placode of flow container, the movement that crane or crane barge is fully utilized makes flow container wirerope institute
It is substantially aligned in position and its location of saddle support aboard ship, then fall tank installation.This method to the stormy waves weather conditions of lifting require compared with
Height limits greatly the size weight of flow container, and the operating time is long, careless slightly that card tank phenomenon may occur.Two lead to be fixed
Rail device, one guiding device of welding equipment above liquid container saddle seat, guide lug on flow container can follows track fall into cabin.This method is implemented
When, to make flow container relatively difficult into guide rail, while fixing the live welding equipment of guide rail and cutting off heavy workload, coating failure mechanics are big,
Guide rail bracket can only first use, it is big to the material loss of batch ship.
We have applied for a patent of invention 200410052784.9, entitled " the active guiding of tank installation in 2004
And positioning device and its installation method ", this method is found that while that goal of the invention can be completed in practice, reaches corresponding invention
Effect, but need to improve there is also some problems: 1. positioning device structures and use are all relative complex, need to install multiple
Matching piece；2. not being able to satisfy quick needs, epoxy resin has been done positioning not yet and has been completed in practice；3. guide rod and guide groove
It is easy to appear when cooperation and blocks or be detached from situation；4. being difficult to adapt to the location and installation of large tank.
Summary of the invention
The technical problem to be solved in the present invention is that overcome above-mentioned the deficiencies in the prior art, provide it is a kind of can be by large-scale flow container
It is quick and precisely positioned into rail, while facilitating installation again and removing, reused lifting guide-localization and installation method.This hair
Fast and accurately localization method is greatly improved the one-time success rate of tank installation to flow container when bright liquefaction vessel is built, and effectively controls
Shipbuilding cost processed.
Technology of the invention solves design: the civilian dress weldering lifting guide plate in flow container manufacture；In block assembly
Otic placode is used in installation and guide device connection in corresponding position in segmentation；The appropriate location setting that flow container hanging ring is corresponded on main deck pulls
Cucurbit eye plate, heavy industry slides into flow container guiding otic placode by pulling chain hoist to adjust flow container position when lifting
In the specific guide groove of dedicated guiding device, rapidly and accurately realizes fall tank location and installation at the appointed time.
