Abstract
The utility model discloses a hollow ship stem comprising a longitudinal purlin plate, a watertight top sealing plate, a left outer plate, a right outer plate, an upper end seal plate, a lower end seal plate, and a plurality of cross partitions, which are molded by protective welding of inert gas. The longitudinal purlin plate is arranged on a central longitudinal section between the left outer plate and the right outer plate, the upper end and the lower end of the longitudinal purlin plate are welded with the top sealing plate and the left and right outer plates respectively, the partitions are arranged between the upper end seal plate and the lower end seal plate, and the distance from the cross partitions to the upper and lower end seal plates is not larger than rib distance of the ship. The hollow ship stem has the advantages that the front end of the hollow ship stem is in a sharp and slim smooth line shape, resistance to the ship is reduced, and water on the stem portion is reduced; the hollow stem is provided with the left and right outer plates, the central purlin plate and the top sealing plate with sufficient thickness, the hollow ship stem has the advantages of good structural strength and light weight; space at the joint of the hollow ship stem and the ship is wide, assembly and welding between the ship structure are facilitated, and full-ship construction period is shortened.
Description
Technical field
The utility model relates to boats and ships manufacture field, refers more particularly to the hollow first post of a kind of boats and ships.
Background technology
The first post of boats and ships is foremost part of ship member foremost, is also one of most important member of hull, and the stringers of outside plate, platform and the topside of foremost part of ship is all to finish at first post place.The first post of boats and ships can ensure foremost part of ship opposing accident collision, and has the hull of reducing resistance to motion, reduces wave in stem, improves the advantages such as overall performance.First post line style is sharper thin, and the effect that reduces resistance is better.Therefore, in conventional structure design, be all to adopt outside plate to be welded on center keelson web, because stem line style is very sharp thin, structure is very complicated conventionally, construction space is very little, construction is difficulty quite, cannot ensure construction quality and line style requirement, and hull head end structural strength cannot be ensured, and be difficult to meet overall requirement, and the problem of constructional difficulties also cannot thoroughly solve.
Utility model content
Technical problem to be solved in the utility model is to provide the hollow first post of a kind of boats and ships, have light, intensity is high, the feature of constructability.
For addressing the above problem, the utility model provides a kind of boats and ships hollow first post, and the section point of first post is made up of longitudinal flitch, top sealing plate, two of left and right outside plate, upper and lower two end-plates and some cross walls, adopts inert-gas welding moulding.
As prioritization scheme, longitudinal flitch is on the center buttock between the outside plate of two of described left and right, and its upper and lower end welds with described top closing plate and left and right outside plate respectively.
Cross wall is between described upper and lower two end-plates, and its spacing is not more than the frame spacing that designs boats and ships, is connected respectively with two of described left and right outside plate in the mode of plug welding.
The beneficial effects of the utility model are:
1. the line style of the fairing that has realized leading section point and become thin, reduces hull resistance, reduces unrestrained phenomenon in stem.
2. have the member such as two of the left and right outside plate of adequate thickness, middle flitch and top sealing plate to strengthen due to hollow first post, therefore it to have structural strength good, lightweight feature.
3. the space spaciousness of hollow first post and hull junction, the assembling between facility and hull structure, welding procedure, can shorten the production cycle of full ship, extremely has generalization.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
Fig. 1 is the lateral plan of the utility model embodiment;
Fig. 2 is the top board outline line birds-eye view of the utility model embodiment;
Fig. 3 is the typical drawing in side sectional elevation of the utility model embodiment;
In figure: 1, longitudinal flitch, 2, top closing plate, 3, cross wall, 4, two of left and right outside plate, 5, upper and lower two end-plates.
Referring to Fig. 1, Fig. 2, Fig. 3, comprise that each longitudinal flitch, top closing plate, cross wall, two of left and right outside plate and upper and lower two end-plates are aluminum alloy material by a longitudinal flitch 1, top closing plate 2, some hollow first post entities of boats and ships that cross wall 3, two of left and right outside plate 4, upper and lower two end-plates 5 are formed a whole.Wherein: longitudinally flitch 1 is one of primary member ensureing hollow first post intensity, the height of hollow first post depends on the minimum width of top closing plate 2, its minimum width will meet the requirement of head end structure construction and meet the area of code requirement, can determine according to the setting-out of stem line style the height of longitudinal flitch 1.Top closing plate 2 is one of primary members that ensure hollow first post intensity and water tightness, the both sides of top closing plate 2 and two ends adopt the process of single face welding and double face shaping to be welded to connect respectively and between two of left and right outside plate 4, upper and lower two end-plates 5 etc., ensure the water tightness of hollow first post.Between cross wall 3 and top closing plate 2 and longitudinal flitch 1, adopt two-sided welding, between cross wall and left and right outside plate, adopt the connection mode of plug welding.Its radical function is to ensure the transverse strength of hollow first post and the fairness of outside plate.Two of left and right outside plate 4 is one of primary members that ensure hollow first post intensity and water tightness, the upper end of two outside plates 4 in left and right and front and back end are connected with ship hull plate docking, lower end is connected with longitudinal flitch 1 overlap joint, adopts the method for plug welding to be connected at rib position place with cross wall 3.Directly adopt the technological process of outside plate docking to be connected the hollow first post entity of entirety and the segmentation of hull stem.The all parts field welds of hollow first post complete polishes surface weld afterwards fairing and carries out tightness test, until acceptance(check).Like this, the first post entity of integral hollow can ensure to meet the relevant regulations of CCS " internal navigation seagoing vessel is built specification " (2012), can ensure again the requirement of strength of hollow first rod structure and meet the requirement of water tightness.
It should be noted last that, above detailed description of the invention is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
