Abstract
A ship-mooring ring for mooring unpowered ships relates to mooring equipment for ships. The problem to be solved by the utility model is to design a ship-mooring ring for typhoon-resistant mooring systems for large and medium unpowered ships. The technical scheme of the utility model adopts an end shackle, and is characterized in that: two L-shaped brackets are respectively welded under the transverse pin holes of both ends of the end shackle; a transverse pin is lengthened, and the lengthened part of the transverse pin is provided with a rectangular hole, in which an open safety pin is inserted; and two earrings are respectively welded on both ends of the transverse pin. The utility model is applicable to ship-mooring rings for mooring large and medium unpowered ships in order to resist typhoon.
Description
Technical field
The utility model relates to the mooring equipment of boats and ships.
Background technology
Boats and ships were built between sailing date, and off host power situation may appear in the part period, promptly self did not have the boats and ships of power-handling capability.During annual typhoon, the anchoring safety and the wind sheltering problem of unpowered boats and ships all face very severe situation, not only relate to people's life and business property safety, and are very great public safety problems.Adopting single buoy mooring system is one of effective way that solves the anti-platform anchoring of large and medium-sized unpowered boats and ships problem.Single buoy mooring system is in the past compared, and applies to the single buoy mooring system of 100,000 tons~300,000 tons of large and medium-sized unpowered boats and ships, has following characteristics: 1, the mooring object is large and medium-sized unpowered boats and ships; 2, mode of operation is exceedingly odious states such as typhoon, and this causes mooring system stressed huge, and stressed size is 6000~10000kN, and is all born by mooring system; 3, be, to take off cable frequent, to being, taking off the operation technological requirement height.Single buoy mooring system is mainly by floating drum, mooring ring, anchor chain and anchor body are formed under water, the single point mooring buoy lower end of anchor chain under water links to each other with the anchor body, the mooring ring of upper end passes floating drum and is shelved on the floating drum, floating drum only limits the downward degree of freedom of mooring ring, when bearing pulling force, mooring ring can freely be extracted floating drum together with anchor chain; Ship anchor chains or hawser directly link to each other with mooring ring, mooring force directly by mooring ring and under water anchor chain be passed to anchorage system.Under the moored condition, floating drum does not bear ship mooring power substantially, only bears How is chain leading and changes the moment of torsion that causes and certain skew back takes place; Non-moored condition, floating drum bear anchor chain weight under water.Floating drum mainly acts on and provides buoyancy and guarantee that the mooring ring of anchor chain stays in the water surface under water, and what be convenient to boats and ships is, takes off the cable operation.Above-mentioned each assembly can be by strengthening floating drum, and overstriking anchor chain, increasing anchor body and intensification anchor body buried depth realize that existing design level and productive capacity all can guarantee to realize, and mooring ring becomes the gordian technique that realizes native system.The requirement that mooring ring need satisfy is: 1) can bear huge pulling force, pulling force needs greater than 6000kN; 2) because pulling force is huge, needing to consider to satisfy is the needs of anchor chain; 3) be convenient to artificial system, take off cable operation.Current mooring ring has following several: 1, " Ω " ring, and according to investigation, the maximum stretching resistance of existing " Ω " ring of producing is about 3000kN, can't satisfy the native system requirement; Open Side Down for " Ω " ring, and lateral pin directly links to each other with anchor chain under water, can not plug, and can only finish heaving pile by binding hawser mode thereon, and hawser is required height, can't be anchor chain.In sum, " Ω " ring can't satisfy the requirement of native system.2, fast system, slip chain hook, the current heaving pile that is mainly used in more external spitkits, it is, it is easy and simple to handle to take off cable, but because cable hook is the single armed tension, is about about 3000kN according to its maximum stretching resistance of investigation.For satisfying the native system requirement, cable hook need adopt better material and manufacture craft to satisfy requirement of strength, and existing no example temporarily can be joined.
The utility model content
Problem to be solved in the utility model is the mooring ring that the anti-platform mooring system of a kind of large and medium-sized unpowered boats and ships of design is used.
The technical solution of the utility model adopts end shackle, it is characterized in that welding " L " type leg rest respectively under the shackle both sides lateral pin hole endways; And the length of lengthening lateral pin, separate an oblong jack, opening safety plug of slot plug-in mounting at the lateral pin lengthening part; Respectively weld an earrings at the two ends of lateral pin.
Of the present utility model owing to end shackle having been welded " L " type leg rest, can rest on the circle shelf that is provided with in the floating drum conical horn mouth, and can not drop under water, anchor chain can upwards pass through floating drum smoothly when tension under water simultaneously, during with assurance ship mooring state, mooring force is directly by anchor chain transmission under water.The end shackle Heavy Weight is difficult to realize the dismounting of lateral pin, respectively welds an earrings at the two ends of lateral pin, be equipped with a cucurbit when practical operation, the end of cucurbit is tied up on the guardrail of floating drum, the other end ties up on the earrings of lateral pin, the operation cucurbit drags lateral pin, can realize the dismounting of lateral pin.
Description of drawings
What accompanying drawing was represented is the assembling scheme drawing of floating drum and mooring ring.
The specific embodiment
The utility model (referring to accompanying drawing) welds " L " type leg rest respectively under the lateral pin hole, both sides of shackle 1 endways, and " L " type leg rest adopts round steel to be processed as " L " type, and the leg rest bottom is tied, and is held on the floating drum so that end shackle is stable; One circle shelf 2 is set in the conical horn mouth of floating drum 3, unload like this and link subsea anchor chain 4 and just can be shelved on the floating drum and can not drop under water, anchor chain can make progress when tension smoothly by floating drum under water simultaneously, and mooring force is directly by anchor chain transmission under water during with assurance ship mooring state.Because the end shackle Heavy Weight under the effect of storm load, is easy to rock on floating drum, be difficult to it is resetted by manpower, leg rest can guarantee that shackle is shelved on the vertical state of maintenance on the floating drum shelf, so that the heaving pile operation.Traditional countersunk head lateral pin length is short, generally after manufacturer's anchor chain heaving pile is finished, fixes safety plug, adopts lead shot that safety plug is sealed, and when operating except changing anchor chain, does not need the lateral pin dismounting generally speaking.The lateral pin of this mooring ring needs frequent dismounting, therefore needs the lateral pin length of lengthening end shackle, and separates an oblong jack at lengthening part, and the oblong jack is adorned an opening safety plug, can realize the frequent dismounting of safety plug; Because lateral pin weight is big, by the artificial dismounting that is difficult to realize lateral pin, respectively weld an earrings at the two ends of lateral pin, tie up on the earrings with cucurbit 5, dilatory lateral pin, being convenient to anchor chain and hawser can be inserted in the lateral pin.
