In order to solve the problems of the technologies described above, the present invention is achieved through following technical scheme:
A kind of underwater structure spare hanging apparatus that is used for platform is equipped with two slide rails on the offshore platform structure, on the said slide rail coaster is installed, and is mounted with jack on the said coaster.
Be connected with brace between said slide rail and the said offshore platform structure.
Said coaster is motor block or manual coaster.
A kind of underwater structure spare hanging method that is used for platform comprises the steps:
A. according to waiting that the weight and the size that lift underwater structure spare carry out design calculation, slide rail and offshore platform structure that slide rail is installed are carried out Force Calculation and strength check, and select to meet slide rail, coaster and the jack of force request;
B., two slide rails are installed on the offshore platform structure above the construction area side by side, on the said slide rail coaster are installed, articulate jack on the coaster;
C. utilize the platform crane will wait to lift the work of lifting of underwater structure spare and support on the ship that work supports that ship is in place to construction area;
D. underwater structure spare is connected with said jack through rigging;
E. operate said coaster and said jack and support ship to sling from work underwater structure spare, and move to the water surface sky of installation site;
F. according to diver's instruction, operate said jack and slowly transfer underwater structure spare, on height level's line of transferring to the place, installation site;
G. according to diver's instruction, operate said coaster parallel motion, the level attitude of underwater structure spare is adjusted, until hoisted in position.
The invention has the beneficial effects as follows:
Hanging apparatus of the present invention and hanging method are abbreviatied, and only need utilize simple facility such as coaster and jack, can realize that through the horizontal displacement of coaster and the vertical lift of jack the lifting of underwater structure spare puts in place.The present invention compares with hanging method with traditional hanging apparatus, and following remarkable advantage is arranged:
(1) construction precision is high, can carry out three-dimensional localization to underwater structure, and level and vertical direction position are adjusted easily;
(2) input equipment facility are simple, and construction cost is cheap;
(3) construction method is simple, and security risk is low;
(4) need not take the original place of platform resource, can not impact during construction platform production;
(5) carry out hanging device and design for scheme flexibly according to the platform actual conditions, can confirm lifting and mount scheme fast and effectively, thereby solve the difficult problem of underwater structure lifting;
(6) equipment is installed and construction required time weak point, and lifting and erection work can settle at one go, have improved work efficiency greatly;
(7) reduce the consumption of the required fuel of platform electric power or boats and ships construction greatly, i.e. environmental protection is economical again;
(8) compare with crane barge, can not cause construction loss or great security risk because of the weather reason.
(9) highly versatile, can extensively be popularized and applied to platform such the construction in go, wide application prospect is arranged.
Under equal work capacity situation, compare with tradition construction pattern, utilize the each construction of the present invention can save about 200,000 yuan of construction cost, have remarkable economic efficiency.
