Abstract
The utility model provides a hatch opening corner of large -scale bulk freighter and ore sand ship locates the hatch opening on -board, and this hatch opening corner of large -scale bulk freighter and ore sand ship is negative angle corner form including corner board, corner board, and the curve shape of corner board comprises two sections tangent circular arcs, and two sections circular arcs have first radius and second radius respectively, and first radial circular arc is tangent with the one side on deck. This hatch opening corner of large -scale bulk freighter and ore sand ship, corner board free edge stress descends, improves fatigue strength, and increase grab bucket working range reduces former material cost, structure safe and reliable.
Description
Technical field
The utility model is related to the hatch opening corner of a kind of large-scale bulk freighter and ore carrier.
Background technology
In the prior art, the hatch corner of large-scale bulk freighter and ore carrier uses as shown in Figure 1 1/4 substantially both at home and abroad
Ellipse, or 1/4 form justified as shown in Figure 2.Using the corner structure type of both, 20 ton bulk freighters are being carried out
, it is necessary to increasing corner thickness of slab and corner radius simultaneously could meet classification society rule's requirement when analysis of fatigue is calculated.But, with
The continuous increase of Ship's Principal Dimensions and hatch opening size, the corner plate thickness of slab and radius for meeting fatigue strength requirement is also required to increase
Plus.So, one side material order difficulty and the cost of raw material increase, and the increase of another aspect corner plate radius reduces handling
, there is potential safety hazard in the efficient working range grabbed bucket during goods.
Utility model content
The technical problems to be solved in the utility model is that, in order to overcome cost increase in the prior art, efficient working range is small
Defect, there is provided the hatch opening corner of a kind of large-scale bulk freighter and ore carrier.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The hatch opening corner of a kind of large-scale bulk freighter and ore carrier, on hatch opening deck, its feature is, institute
The hatch opening corner for stating large-scale bulk freighter and ore carrier includes corner plate, and the corner plate is negative angle corner form, the angle
The curve shape of corner plate is made up of two sections of tangent circular arcs, and two sections of circular arcs have the first radius and the second radius, institute respectively
The circular arc for stating the first radius is tangent with the one side on the deck.
It is preferred that first radius is more than second radius.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, obtain final product the utility model it is each compared with
Good example.
Positive effect of the present utility model is：
The hatch opening corner of a kind of large-scale bulk freighter and ore carrier in the utility model, under corner plate free edge stress
Drop, improves fatigue strength, and increase grab bucket working range reduces the cost of raw material, and structure is safe and reliable.
Brief description of the drawings
Fig. 1 is the medium-and-large-sized bulk freighter of prior art and the oval corner structural representation of ore carrier 1/4.
Fig. 2 is the medium-and-large-sized bulk freighter of prior art and the fillet corner structural representation of ore carrier 1/4.
Fig. 3 is the hatch opening corner structural representation of the large-scale bulk freighter and ore carrier of the preferred embodiment of the utility model one
Figure.
Description of reference numerals：
1：Corner plate
2：Deck
R1：First radius
R2：Second radius
Specific embodiment
Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.
As shown in figure 3, the hatch opening corner of a kind of large-scale bulk freighter and ore carrier, on hatch opening deck 2, greatly
The hatch opening corner of type bulk freighter and ore carrier includes corner plate 1, and corner plate 1 is negative angle corner form, the curve of corner plate 1
Shape is made up of two sections of tangent circular arcs, and two sections of circular arcs have the first radius R1 and the second radius R2 respectively, the first radius R1's
Circular arc is tangent with the one side on deck 2, and the first radius R1 is more than the second radius R2.
After using the corner structure type shown in Fig. 3 in the present embodiment, by finite element analysis, carry out fatigue mechanisms and obtain
The maximum stress value for going out the free margins of hatch opening corner plate 1 of same thickness of slab can decline more than 15%, and to the shape of corner plate 1
Into natural protection, the security of structure is increased, reduce the cost of raw material, it is favourable to construct and do not influence ship normally to operate
Requirement.
The group of suitable thickness of slab and radius according to the analysis of fatigue result of not shipmate type, can be selected in the present embodiment
Close, with stronger flexibility and reliability.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
On the premise of without departing substantially from principle of the present utility model and essence, various changes or modifications can be made to these implementation methods,
But these changes and modification each fall within protection domain of the present utility model.
