Utilizing the platform crane lifting is lifting mode the most conveniently, can faster the structural member lifting be put in place, but in the engineering construction of reality, a lot of construction locations is in the zone that the platform crane can't cover, and can't utilize crane directly to lift.
Utilize the hoist engine lifting to need to make interim lifting frame, articulate assembly pulley and wire rope etc. at lifting frame welding hanger, also need accurate addressing is carried out in the hoist engine installation site, remove the structures such as original platform windbreak, guardrail, hanging device installation, dismounting and location workload are larger; The method is larger to the space requirement of construction area, and a lot of construction area exactly can't be installed hoist engine owing to limit by site space.In addition, the vertical orientation that hoist engine lifting only can the control structure thing, horizontal position adjustment difficulty.
The crane barge lifting can faster put the structural member lifting in place, but its construction cost is high, needs to flow to the location of casting anchor according to routing diagram and seawater, and the security risk in cast anchor location and the hoisting process is higher, and it is larger affected by weather and sea situation, is difficult to accurately control construction precision.
Simultaneously, the lifting of ocean platform underwater structures spare requires high-precision adjustment is carried out in its position usually, to reach installation requirement.Utilize the facility such as hoist engine, crane barge all can be because of various condition restriction or impact and be difficult to carried out the adjustment of high-precision position by hoisting structure spare, need the diver to adjust in place by instruments such as guide chains under water, construction precision is lower, and is long in time limit, also has higher security risk.
The utility model content
To be solved in the utility model is above-mentioned technical problem of the prior art, and a kind of underwater structures spare hanging apparatus for ocean platform is provided, and easy and simple to handle, with low cost, construction safety is efficient.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of underwater structures spare hanging apparatus for ocean platform is equipped with two slide rails on the offshore platform structure, on the described slide rail coaster is installed, and is mounted with jack on the described coaster.
Be connected with brace between described slide rail and the described offshore platform structure.
Described coaster is electric hoist or manual coaster.
The beneficial effects of the utility model are:
Hanging apparatus of the present utility model is abbreviatied, and only need utilize the simple facility such as coaster and jack, can realize that by the horizontal shift of coaster and the vertical lift of jack the lifting of underwater structures spare puts in place.The utility model is compared 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) utilize the job practices of this device simple, security risk is low;
(4) need not take the original place of platform resource, can not impact platform production during construction;
(5) carry out flexibly the design of hanging device and scheme according to the platform actual conditions, can determine fast and effectively lifting and mount scheme, thereby solve the difficult problem of underwater structure lifting;
(6) equipment is installed and construction required time weak point, and lifting and installation work can settle at one go, have improved greatly operating efficiency;
(7) greatly reduce the consumption of the required fuel of platform electric power or boats and ships construction, 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 ocean platform such the construction in go, have broad application prospects.
In equal workload situation, compare with traditional Construction Mode, utilize the each construction of the utility model can save about 200,000 yuan of construction cost, have significant economic benefit.
