Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a connection structure of a sealing plate and a cargo unloading plate of a welded grooved bulkhead. Background Art

[0002] The corrugated bulkhead is used to divide the cargo hold of a ship. It is named corrugated bulkhead because it is made of corrugated plates instead of flat plates. The corrugated bulkhead can be divided into two types: press-bent type and welded type according to its processing technology. In the structure of the welded corrugated bulkhead, the corrugated face plate and the corrugated web are connected by welding.

[0003] As the name suggests, a loading board is a board that is tilted downwards and designed to prevent cargo from piling up. Figure 1 As shown in the figure, due to the existence of the groove in the corrugated bulkhead, an area surrounded by the grooved face plate 101, the grooved web plate 102 and the bottom plate is prone to cause cargo accumulation, and the inclined plate arranged in this area is called a cargo unloading plate 103. A vertical plate used to support the cargo unloading plate 103 is called a sealing groove plate 104.

[0004] In the conventional design of welded corrugated bulkheads, there are four welds at the intersection of the corrugated face plate, corrugated web, unloading plate and corrugation sealing plate, namely: full penetration welding of corrugated web and corrugated face plate; butt welding of corrugated web and corrugation sealing plate; butt welding of corrugation sealing plate and unloading plate; full penetration welding of single-sided opening of unloading plate and corrugated web. The disadvantages of this structure are: troublesome construction, more welding, and it is not easy to ensure the welding quality of stress concentration points.

[0005] In another existing design, two plates are added to solve the high stress problem at the corners. However, due to the addition of two plates, the number of welds at the corners increases from 4 to 6, making the construction more troublesome. In addition, due to the increase in parts and welds, the welding quality is not easy to ensure. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a connection structure between a sealing plate and a cargo unloading plate of a welded grooved bulkhead.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A structure for the connection between a sealing groove plate and a cargo unloading plate of a welded trough-shaped bulkhead, comprising a trough panel, a trough web, a sealing groove plate and a cargo unloading plate, wherein the trough panel and the trough web are welded and connected, the sealing groove plate is connected to the trough panel, and the cargo unloading plate is simultaneously connected to the trough web and the sealing groove plate; a sealing groove plate is respectively connected to both sides of the trough panel, and a toggle plate is respectively connected to each of the two sealing groove plates, the two toggle plates are respectively connected to both sides of the trough panel, and the free edges of the toggle plates are arc-shaped; the trough panel, the two sealing groove plates and the two toggle plates are integrally formed; an inclined plate with a cargo unloading function is fixedly arranged on the rear end face of the toggle plate, and the inclined plate is simultaneously connected to the trough web and the cargo unloading plate.

[0009] Preferably, the rear end surfaces of the two toggle plates are respectively provided with an inclined plate.

[0010] Preferably, the oblique plates are distributed obliquely downward from the groove web to the outer side of the groove web.

[0011] Preferably, the connection between the oblique plate and the bracket is not higher than the free edge of the bracket.

[0012] Preferably, the area of ​​the diagonal plate is smaller than the area of ​​the unloading plate.

[0013] Preferably, the diagonal plate closes the area on the rear side of the toggle plate which is surrounded by the groove web, the unloading plate and the toggle plate.

[0014] Preferably, the channel panel, the two channel sealing plates and the two toggle plates are located on the same plane.

[0015] Preferably, the oblique plate and the toggle plate are connected by welding.

[0016] Preferably, the inclined plate and the unloading plate are connected by welding.

[0017] Preferably, the unloading plate and the channel web are connected by welding.

[0018] The beneficial effects of the present invention are as follows: the present invention solves the problem of high stress, greatly reduces the stress at the corner point, and increases the life of the hull. The present invention reduces the number of welds at the original corner point to 3. Due to the reduction of welds, the construction difficulty is greatly reduced, the construction is more convenient, and it is more conducive to controlling the welding quality.

[0023] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, a structure of the connection between the sealing plate and the unloading plate of a welded corrugated bulkhead includes a corrugated panel 201, a corrugated web 202, a sealing plate 203 and an unloading plate 204. The corrugated panel 201 and the corrugated web 202 are welded together, the sealing plate 203 is connected to the corrugated panel 201, and the unloading plate 204 is simultaneously connected to the corrugated web 202 and the sealing plate 203.

[0025] A sealing plate 203 is connected to each side of the groove panel 201, and a toggle plate 205 is connected to each of the two sealing plates 203. The two toggle plates 205 are connected to each side of the groove panel 201, and the free edges of the toggle plates 205 are arc-shaped.

[0026] The groove panel 201, the two groove sealing plates 203 and the two toggle plates 205 are integrally formed. The groove panel 201, the two groove sealing plates 203 and the two toggle plates 205 are located on the same plane. The groove panel, the two groove sealing plates and the two toggle plates are processed from a whole piece of steel plate, which has the advantage of convenient construction.

[0027] An inclined plate 206 with a cargo unloading function is fixedly disposed on the rear end surface of the toggle plate 205 , and the inclined plate 206 is connected to the groove web 202 and the cargo unloading plate 204 at the same time.

[0028] An inclined plate 206 is respectively provided on the rear end surface of the two toggle plates 205 .

[0029] The oblique plate 206 is distributed obliquely downward from the groove web to the outside of the groove web. Like this, the problem of stacking of goods will not occur when falling on the oblique plate.

[0030] The connection between the oblique plate 206 and the toggle plate 205 is not higher than the free edge of the toggle plate. The oblique plate is located below the rear side of the toggle plate.

[0031] The area of ​​the inclined plate 206 is smaller than the area of ​​the unloading plate 204 .

[0032] The region surrounded by the groove web, unloading plate and toggle plate at the toggle plate rear side is sealed by the oblique plate 206. Like this, goods can not fall into the region surrounded by the groove web, unloading plate and toggle plate, avoids the accumulation of goods.

[0033] The inclined plate and the bracket, the inclined plate and the unloading plate, and the unloading plate and the groove web are all welded.

[0034] The present invention integrates the groove panel, the groove sealing plate and the toggle plate into an integrated design, which has the following beneficial effects:

[0035] 1. Solved the problem of high stress, greatly reduced the stress at the corners, and increased the life of the hull.

[0036] 2. Reduce the number of welds at the original corner point to 3, which are: the weld between the groove panel and the groove web; the weld between the groove panel and the unloading plate; the weld between the unloading plate and the groove web.

[0037] 3. As the number of welds is reduced, the construction difficulty is greatly reduced, the construction is more convenient, and it is more conducive to controlling the welding quality.

[0038] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims.
