Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a cargo unloading structure for the top plate of a trough-shaped bulkhead and a ship. Background Technology

[0002] For ease of loading and unloading, liquid cargo ships and bulk carriers typically have transverse bulkheads in their cargo hold areas designed as transverse trough-shaped bulkheads. To prevent cargo residue from being left after unloading, unloading plates are installed at the lower end of the trough-shaped section that curves towards the stern.

[0003] like Figure 1 As shown, conventional unloading plates are typically installed on top of the bulkhead and connected to the trough-shaped bulkhead. The junction between the unloading plate and the trough-shaped bulkhead forms a high-stress point, a high-stress concentration area or fatigue-prone area, making the structure prone to damage and cracking, and a high-risk area for accidents during actual operation. The narrow space formed by the trough-shaped bulkhead and the unloading plate makes welding and construction operations difficult, inspection operations challenging, and welding quality poor, leading to frequent problems with defective welds. In addition, the small space formed by the unloading plate and the trough-shaped bulkhead forms an air pocket during operation, where the accumulated gas cannot escape, creating a high-pressure area and posing a safety hazard. Finally, the connection between the unloading plate and the bulkhead / bullet needs to be completed during the final assembly stage on the slipway, resulting in a long slipway construction period and a poor construction environment. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a cargo unloading structure and a ship with a trough-shaped bulkhead top plate. By setting a downwardly concave unloading plate at the top of the lower bulkhead of the trough-shaped bulkhead, the unloading plate is prevented from connecting with the trough-shaped bulkhead, thus avoiding high stress areas and preventing damage or cracking of the trough-shaped bulkhead.

[0005] The objective of this invention is achieved through the following technical solution: a trough-shaped bulkhead pier top plate unloading structure, comprising a trough-shaped bulkhead, a pier top plate, pier side plates, and an unloading plate.

[0006] Among them, the groove-shaped bulkhead with its concave shape towards the tail is provided with an inner groove opening at the corresponding position of the top plate of the bulkhead, and the unloading plate is inclinedly set in the groove opening.

[0007] The unloading plate is connected to the top plate and side plate of the pier, but not to the trough-shaped bulkhead.

[0008] Preferably, the unloading platform includes a side plate and an inclined plate, wherein the side plate is disposed at both ends of the slot in the top plate of the wall pier, the inclined plate is disposed obliquely in the slot, the inclined plate is connected to the top plate and the side plate of the wall pier, and the inclined plate is not connected to the trough-shaped bulkhead.

[0009] Furthermore, the side panels and ramps of the unloading platform can be integrally molded independent components.

[0010] Furthermore, the inclination angle between the unloading platform and the top plate of the wall pier is 5°-45°.

[0011] Furthermore, the thickness of the side plates and inclined plates of the unloading platform is greater than or equal to that of the top plate of the wall pier, and the material is the same as that of the top plate of the wall pier.

[0012] Furthermore, the side plates and inclined plates of the unloading platform are welded to the top plate of the wall pier using a full penetration weld.

[0013] Furthermore, the distance between the side plate of the unloading platform and the corner of the trough is greater than or equal to 50mm.

[0014] Preferably, ventilation holes are provided on the side panels of the unloading platform.

[0015] Preferably, the shape of the ramp of the unloading platform includes, but is not limited to, semi-circular, arc-shaped, and flared.

[0016] In addition to providing a cargo unloading structure for the top plate of a trough-shaped bulkhead, the present invention further provides a ship including the above-mentioned cargo unloading structure.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention provides a cargo unloading structure and ship with a trough-shaped bulkhead pier top plate. By setting a downwardly inclined unloading plate at the bottom pier top plate of the trough-shaped bulkhead and designing the unloading plate at a certain downward angle, it is easy to tilt the cargo and solve the problems of cargo accumulation and residue.

[0019] In this invention, the unloading plate is not connected to the trough-shaped bulkhead, avoiding the problem of connecting the unloading plate to the high-stress points of the trough in traditional designs. This avoids high-stress areas and prevents damage or cracking of the trough-shaped bulkhead. Furthermore, the welding of the unloading plate to the top and side plates of the bulkhead piers uses easy-to-construct and weld diagonal welds, simplifying the operation. The connection does not create small spaces, facilitating inspection and avoiding problems with poor welding quality.

[0020] The unloading structure on the top plate of the trough-shaped bulkhead provided by this invention solves the problems of construction difficulties and safety hazards in the narrow space formed by the unloading plate and the trough-shaped bulkhead. By opening ventilation holes on the side plate, it solves the problem of air pockets forming in the narrow space formed by the unloading plate and the trough-shaped bulkhead, ensuring smooth flow of gas and liquid without the problem of gas accumulation and blockage.

[0021] The unloading structure for the top plate of the trough-shaped bulkhead provided by this invention can move the unloading plate installation process to the small closure stage, which is beneficial to improving construction quality and construction environment, reducing the construction cycle of the slipway, and reducing costs.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] The present invention provides a trough-shaped bulkhead top plate unloading structure, including a trough-shaped bulkhead 1, a top plate 2, a side plate 3, and an unloading plate 4.

[0032] Among them, the groove-shaped bulkhead 1 with its concave shape towards the tail is provided with an inner groove opening 5 at the corresponding position of the top plate of the bulkhead 2, and the unloading plate 4 is inclinedly placed in the groove opening 5.

[0033] The unloading plate 4 is connected to the top plate 2 and the side plate 3 of the wall pier, but the unloading plate 4 is not connected to the trough-shaped bulkhead 1.

[0034] like Figures 2 to 3 As shown, in some embodiments of the present invention, the unloading plate 4 includes a side plate 6 and an inclined plate 7. The side plate 6 is disposed at both ends of the slot 5 of the top plate 2 of the wall block, and the inclined plate 7 is disposed obliquely in the slot 5. The inclined plate 7 is connected to the top plate 2 of the wall block and the side plate 3 of the wall block, and the inclined plate 7 is not connected to the trough-shaped bulkhead 1.

[0035] In some embodiments of the present invention, the side plate 6 and the inclined plate 7 of the unloading plate 4 may be integrally formed independent components.

[0036] In some embodiments of the present invention, the tilt angle between the unloading plate 4 and the top plate 2 of the wall pier is 5°-45°.

[0037] In some embodiments of the present invention, the thickness of the side plate 6 and the inclined plate 7 of the unloading plate 4 is greater than or equal to that of the top plate 2 of the wall pier, and the material is the same as that of the top plate 2 of the wall pier.

[0038] In some embodiments of the present invention, the side plates 6 and inclined plates 7 of the unloading plate 4 are welded to the top plate 2 of the wall pier in a full penetration manner.

[0039] In some embodiments of the present invention, the distance between the side plate 6 of the unloading plate 4 and the trough-shaped corner is greater than or equal to 50 mm.

[0040] In some embodiments of the present invention, ventilation holes 8 are provided on the side plate 6 of the unloading plate 4.

[0041] In some embodiments of the present invention, the shape of the inclined plate 7 of the unloading plate 4 includes, but is not limited to, a semi-circular shape, an arc shape, and a trumpet shape.

[0042] The following example further illustrates the unloading structure of the top plate of the trough-shaped bulkhead pier provided in the technical solution of this invention:

[0043] like Figures 2 to 3 As shown, the unloading structure of the trough-shaped bulkhead pier top plate includes a trough-shaped bulkhead 1, a pier top plate 2, pier side plates 3, and an unloading plate 4. The trough-shaped bulkhead 1 has an indentation 5 corresponding to the pier top plate 2 at its concave stern. The unloading plate 4 includes side plates 6 and inclined plates 7. The side plates 6 are located at both ends of the indentation 5 in the pier top plate 2, and the inclined plates 7 are inclinedly positioned within the indentation 5. The inclined plates 7 are connected to the pier top plate 2 and the pier side plates 3, but not to the trough-shaped bulkhead 1. This separation of the unloading plate from the trough-shaped bulkhead avoids the problem of connecting the unloading plate to high-stress points in traditional designs, thus avoiding high-stress areas and preventing damage or cracking of the trough-shaped bulkhead.

[0044] like Figure 4 As shown, in this embodiment, the side plate 6 and the inclined plate 7 of the unloading plate 4 are integrally formed independent components, and the inclined plate is semi-circular in shape. Figure 5 As shown, the inclination angle between the unloading plate 4 and the top plate 2 of the pier is 30°. The thickness of the side plate 6 and the inclined plate 7 of the unloading plate 4 is equal to that of the top plate 2 of the pier, and their materials are the same. The welding of the side plate 6 and the inclined plate 7 of the unloading plate 4 to the top plate 2 of the pier is a diagonal weld, using a full penetration weld, which is simple to operate, does not form a small space after connection, is easy to inspect, and avoids the problem of poor welding quality.

[0045] like Figure 6 As shown, the distance between the side plate 6 of the unloading plate 4 and the corner of the trough is 50mm. Figures 6 to 7As shown, the side plate 6 of the unloading plate 4 is provided with ventilation holes 8. By opening ventilation holes on the side plate, the problem of air pockets forming in the narrow space formed by the unloading plate and the tank wall is solved, and gas and liquid flow smoothly without the problem of gas accumulation.

[0046] By adopting the trough-shaped bulkhead pier top plate unloading structure in this embodiment, the unloading plate installation process can be moved forward to the small closure stage, which is conducive to improving construction quality and construction environment, reducing the construction cycle of the slipway, and reducing costs.

[0047] In addition to providing a trough-shaped bulkhead top plate unloading structure, the present invention further provides a ship including the above-mentioned unloading structure.
