The specific embodiment
Chain stopper based on strengthening structure on ship of the present invention as Figure 1-4, chain stopper main body 4 is seated at chain stopper bottom and strengthens in structure.Concrete with reference to figure 1-9, in figure, dotted portion is chain stopper main body 4.Wherein, strengthen structure and comprise the bow side direction lower reinforcing plate 1 of subordinate's brace panel 2 and both sides forward that is positioned at 6 belows, deck.Shown in Fig. 5, bow is subordinate's brace panel 2 and deck out of plumb forward, to stem inclination 10-20 degree; The middle front part of side direction lower reinforcing plate 1 is provided with bow to middle part lower reinforcing plate 3, and bow is to middle part lower reinforcing plate 3 and deck out of plumb, to ship stern inclination 10-20 degree.
As shown in Figure 4, side direction lower reinforcing plate 1, bow forward subordinate's brace panel 2, bow surround a U-shaped scope that is greater than chain stopper base for 6 times on deck to middle part lower reinforcing plate 3, certain surplus are provided to the installation of chain stopper.Wherein, surplus need to guarantee installation strength, and the while guarantees easy for installation again, and therefore, under optimal way, side direction lower reinforcing plate 1 is outwards offset 60-100mm compared with chain stopper main body 4; The bow forward more described chain stopper main body of subordinate's brace panel 2 is outwards offset 30-50mm; Bow is to the inside ship stern of the more described chain stopper main body of middle part lower reinforcing plate 3 direction skew 60-100mm.
The acquisition of above-mentioned side-play amount is according to on-the-spot for many years chain stopper installation experience, and the error condition of adding up actual installation position and desirable design attitude obtains.The boats and ships that the present invention is particularly useful for more than 4 tons arrange chain stopper, and 40,000 tons of following boats and ships, because installation error is less, generally do not adopt the present invention.
Due to anchor chain device institute bearing load direction be mainly bow to, so the present invention at bow to twice lower reinforcing plate is set, to meet requirement of strength.Specifically, be provided with bow to middle part lower reinforcing plate 3, and to the relative rearward position of middle part lower reinforcing plate 3, be provided with the anterior upper reinforcing plate 5 of base to stem inclination 10-20 degree with bow above chain stopper lower body part both sides are positioned at deck 6.
As shown in Figure 5, on base front portion, strengthen 5 and be positioned at chain stopper base both sides, be arranged in chain stopper base front portion but not chain stopper base front end, apart from bow to middle part lower reinforcing plate 3 to stern, be offset 60-100mm, to the oblique 10-20 degree of trim by head.In addition, lateral loading is less, so strengthen at laterally disposed one time, middle part is not set and strengthens; Stern is to being subject to hardly load, so lower reinforcement is not set at chain stopper afterbody; Meanwhile, for meeting bow to requirement of strength, anterior upper reinforcement is set above deck.
It is example that the 320000 VLCC oil carrier chain stoppers of take are below strengthened structure, by utilizing the analysis of finite element model, and the assessment of a plurality of layouts is selected, and illustrates that the present invention can provide the advantage of the chain stopper reinforcement structure that surplus is installed.As shown in Figures 4 and 5, side direction lower reinforcing plate 1 is to both sides skew 100mm, because lateral loading is less, not because lower reinforcement does not increase thickness of slab with chain stopper contraposition, intermediate altitude 500mm, and the anti-dumping panel of 100mm is set, the end form of high 300mm radius 400mm is set simultaneously.As shown in Figure 5, bow forward subordinate's brace panel 2 is offset 50mm to bow, due to bow to load larger, for meeting requirement of strength, the thickness of slab of lower reinforcement is increased to 50mm by original 20mm, intermediate altitude 300mm, and the end form of high 300mm radius 400mm is set, because the effect that prevents that the reinforcement of twice side direction from reversing is born in the downward reinforcement of bow simultaneously, so being enhanced to right side from left side, employing strengthens continuous design; As shown in Figure 7, bow subordinate's brace panel 2 is forward set separately, can not meet requirement of strength completely, bow need to be set to middle part lower reinforcing plate 3, bow is offset 100mm to middle part lower reinforcing plate 3 to stern, for meeting requirement of strength, the thickness of slab of lower reinforcement is increased to 50mm by original 20mm, adopt the kneepiece form of 300mm * 500mm. due to bow forward subordinate's brace panel 2 adopted continuous structure, bow just can adopt split-type structural to middle part lower reinforcing plate 3; Simultaneously due to bow forward subordinate's brace panel 2 apart from bow, to middle part lower reinforcing plate 3, only have 150mm, distance is very little, to site operation, bring difficulty, for Solve problems in construction, increase the distance that twice are strengthened as far as possible, bow forward subordinate's brace panel 2 is oblique to trim by head, under optimal way, adopt 15 degree, bow tilts to middle part lower reinforcing plate 3 to stern, adopts 15 degree under optimal way, and bow can adopt split-type structural to be also conducive to site operation to middle part lower reinforcing plate 3.As shown in Figure 8, for meeting requirement of strength, the anterior upper reinforcing plate 5 of chain stopper base is positioned at chain stopper base both sides, be arranged in chain stopper base front portion but not chain stopper base front end, apart from bow to middle part lower reinforcing plate 3 to stern, be offset 100mm, the thickness of slab of reinforcement is 50mm, adopts the kneepiece form of 300mm * 500mm, to stern inclination certain angle, under optimal way, adopt 15 degree.In addition,, for strengthening structural strength, deck 6 is increased to 50mm by original 20mm.
Under prior art, to strengthen the mechanics principle of structure be the contraposition that structure is strengthened in application to chain stopper, makes load that chain stopper bears by tension and compression mode, is delivered to reinforcement structure, thereby is delivered to hull structure.The principle of design that the present invention can provide the chain stopper that surplus is installed to strengthen structure is the not contraposition that structure is strengthened in application, makes load that chain stopper bears by deck and the cut mode strengthened up and down, passes to reinforcement structure, thereby transmits hull structure.Because the anti-shear ability that improves material is mainly by increasing the thickness of slab of material, so the present invention has increased the thickness of slab of some, once there is to revise the needed work such as plate, welding, polishing, application of changing but compare, still save cost, simplified technique, improved work efficiency.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
