Industry is required for carrying out by lowering or hoisting gear.Jacking system is platform in platform towage, standing work, storm under the operating mode such as depositing
Ensure its safe most critical part, its performance directly influences the safety and its using effect of platform.
Lifting device structure is located at the junction of the spud leg on jack-up unit main hull open deck, main platform body
Linked together between spud leg by lifting tower structure.Its structure type has much relations with spud leg type.
Lifting tower structural bearing caused dynamic loading during huge agent structure and lifting platform ship, also needs full
The intensity requirement of the sufficient various working conditions of platform.Under normal circumstances, lifting device structure has structure type complexity, intensity requirement
The features such as high, so ultrahigh-strength steel plates use ratio is big, steel plate thickness is also larger, and welding capacity increases therewith, therefore compares appearance
It is also easy to produce welding deformation.And the construction of lowering or hoisting gear requires very high, therefore jacking system structure is the difficulty of whole platform construction
Point.In the construction cost of self-elevating drilling platform, jacking system structure also occupies sizable proportion.
In general, traditional lowering or hoisting gear has an independent lifting device structure unit at each rack, described
Connected between traditional lifting device structure unit by large-scale down tube.Each lifting device structure unit is similar cuboid
Box-structure, steel plate is thick and narrow space, is unfavorable for site operation.Moreover, each lifting structure unit is both needed to root
Close up according to the positioning of ground sample, very big workload is brought to scene.
Utility model content
The purpose of this utility model is to provide a kind of structure strengthened for multifunctional platform lowering or hoisting gear.
The technical solution adopted in the utility model is：
A kind of structure strengthened for multifunctional platform lowering or hoisting gear, it is characterised in that：Including located at the hexagonal enclosed on well
Box-structure, grillage, the hexagonal box-structure is fixedly connected on by grillage to be enclosed at the top of well, below the hexagonal box-structure
Grillage formed hollow structure in gear-box is set, the gear-box top and bottom is individually fixed in hexagonal box-structure bottom
Portion and enclose at the top of well, the hexagonal box-structure is to include upper cover plate, lower shoe and three short sides, the axle pair of three long side surfaces
Claim structure, the short sides are set gradually with long side surface is fixed on upper cover plate and lower shoe, and the hexagonal box-structure is at three
Population is equipped with short sides, the hexagonal box-structure is equipped with longitudinally disposed sliding way, the upper cunning on the inside of population
Road is correspondingly provided with glide path enclosing in well, the sliding way with, through there is spud leg rack, the spud leg rack passes through in glide path
Spud leg down tube is fixedly connected.
The sliding way is with glide path on same axis.
The framed plate structure is in horn-like expansion downwards.
Three spud leg racks set gear-box respectively.
The advantages of the utility model：Reinforcement structure inner hollow, it is in light weight, material cost is saved, structure working space fills
Foot, beneficial to construction is built on-site, it is segmented as an entirety during folding structures, only needs according to ground sample positioning once during positioning,
Even structure bears, transmits hull loads, and structural strength is higher.
