Abstract
The utility model discloses a ship stem which is low in cost, low in energy consumption and easy to machine. The ship stem comprises a stem body which is divided into two parts. The upper part is a steel plate section and the lower part is a round bar steel section, wherein the steel plate section is connected with the round bar steel section. A connection notch is arranged at the outer side of the end, connected with the round bar steel section, of the lower portion of the steel plate section.
Description
Technical field:
The utility model relates to a kind of shipping stempost.
Background technology:
Stem, shipping stempost are boats and ships bow members foremost, also are one of most important members of hull, and the stringers of the outside plate of boats and ships bow, deck, platform and topside all is to finish at the stem place.
Stem is a primary structure member, bear the fierceness collision of various External Force Actings, particularly hull and other object.It can strengthen hull bear wave impact force and hydraulic pressure, can also bear the vibrations of longitudinal impact.So stem will have enough Rigidity and strengths, can bear various external impacts.
On small boat, different according to manufactured materials and manufacture, stem has following several:
The steel plate stem is welded with plate iron, and vertically being provided with reinforced rib, laterally is provided with horizontal bracket, and is integrally welded.The advantages such as the steel plate stem has lightweight, and technique is simple, but impact resistance is relatively poor, yielding, generally be used for the not high boats and ships of requirement of strength.
The cast steel stem is cast with steel and to be formed, and good rigidity can be cast various complicated shapes.But, Heavy Weight, so it is applicable to the section shape complexity, the place that rigidity requirement is high.
Hybrid stem is made steel casting underwater, and topsides is made the steel plate stem, these two sections weld togethers.This hybrid stem has been taken into account the advantage of cast steel stem and steel plate stem, so, usually adopt hybrid stem on more modern large ships.
Concerning small boat, the general steel plate that adopts is done stem, but concerning the miniature high-speed ship, for reducing the wave making resistance of boats and ships bow, usually all design near the bow end shape of several waterlines design load water line and the design load water line very sharp thin, its arc radius is generally all very little, that is to say that near its arc radius of the section of stem design load water line is very little, this too small arc radius is difficult to processing with steel plate, can not guarantee the smoothness of appearance; The cost of cast steel stem is high, and power consumption is large, and the feature of environmental protection is poor, and Heavy Weight is inapplicable concerning the high speed vessel that weight control is arranged; The hybrid stem of steel casting is adopted in the bottom, also has the problem of high cost concerning the miniature high-speed ship.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, the shipping stempost that a kind of cost is low, consume energy less, be easy to process to be provided.
Problem to be solved in the utility model, can realize by following technical scheme: a kind of shipping stempost, include the stem body, the stem body is divided into two parts, and top is the steel plate section, and the bottom is the round steel section, and the steel plate section is connected with the round steel section.
The end outside that is connected with the round steel section in the bottom of steel plate section is provided with the connection otch.
The design uses hybrid stem, and underwater cast steel changes into round steel to be processed, and both compare, and this stem has following characteristics:
1. cost is lower than cast steel, and power consumption is few
2. compare simply in processing technology, steady quality, cast steel bow spare easily produces pore at casting process, before installation
Still need a large amount of polishings of proofreading and correct, there is not pore in the round steel stem, proofreaies and correct relatively easy yet.
3. the lower carbon steel of steel casting normal operation carbon content is more or less the same in weight with the round steel stem.
Description of drawings:
Fig. 1 is the constructional drawing of the utility model shipping stempost;
Fig. 2 is the decomposition chart of the utility model shipping stempost;
Fig. 3 is the vertical sectional structure chart after the utility model shipping stempost is installed to boats and ships;
Fig. 4 is the A-A sectional structure chart of Fig. 3;
Fig. 5 is the end TV structure figure after the utility model shipping stempost is installed to boats and ships.
The specific embodiment:
Below in conjunction with accompanying drawing present technique is described further.
The shipping stempost of this example includes stem body 1, stem body 1 is divided into two parts, top is steel plate section 11, the bottom is round steel section 12, steel plate section 11 is connected with round steel section 12, the end outside that is connected with round steel section 12 in the bottom of steel plate section 11 is provided with and connects otch 13, and the degree of depth of this connection otch 13 conforms to round steel thickness, and purpose is to connect for convenient.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
