Description

Technical Field

[0001] This invention relates to the field of ship structural engineering technology, specifically to a collision protection platform structure for a large loading hold and the large loading hold itself. Background Technology

[0002] Currently, many transport ships are equipped with large loading holds for loading cargo. However, for small and medium-sized aluminum alloy transport ships with large loading holds, the space in these holds is not very large due to their small size. Therefore, due to the limited space in the loading holds, there is a significant risk of collision between vehicles and the main hull bulkheads and cable pipelines during loading and unloading. If a collision occurs, it will directly affect the safe use of the main hull structure. In addition, the cost and time required for repairing the main hull structure, pipelines, and cables will be relatively high.

[0003] Therefore, the above-mentioned technologies have the problem that the large loading compartment is prone to collisions during loading, resulting in high maintenance costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that existing small and medium-sized aluminum alloy transport ships are prone to collisions when loading cargo, resulting in damage to the loading holds and cable pipelines, and high maintenance costs.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is to provide a collision protection platform structure for loading large compartments, including a detachable upper panel, an upper side panel, a lower side panel, a perforated transverse bulkhead, and bow and stern sealing plates. The detachable upper panel includes an upper panel that is placed horizontally. Two bow and stern sealing plates are provided and vertically arranged. The upper ends of the bow and stern sealing plates are connected to the shorter two sides of the upper panel, and the upper ends of the upper side panels are connected to the longer side of the upper panel. The sides of the upper side panels are connected to the sides of the bow and stern sealing plates. The upper end of the lower side plate is connected to the lower end of the upper side plate, and the lower end of the lower side plate is flush with the lower end of the bow and stern sealing plates. Multiple perforated transverse bulkheads are provided. The perforated transverse bulkheads are parallel to the bow and stern sealing plates and are located below the detachable upper panel. The perforated transverse bulkheads are connected to the detachable upper panel, upper side plate, and lower side plate. The detachable upper panel, upper side plate, lower side plate, and bow and stern sealing plates are assembled and connected to form a thin-walled box with an opening at the bottom and on one side. The side opening of the thin-walled box is connected to the side wall of the loading compartment, and the bottom of the thin-walled box is connected to the loading deck.

[0006] By adopting the above technical solution, and by setting up a thin-walled box body composed of a detachable upper panel, upper side panel, lower side panel, perforated transverse partition and bow and stern sealing plate, and installing it in the loading compartment, it can collide with the vehicle before the side wall of the loading compartment and the cable pipeline. Through its own flexible deformation, it releases the collision energy, which can effectively prevent the vehicle from directly colliding with the side wall of the loading compartment and the cable pipeline, thereby reducing damage to the loading compartment and the cable pipeline and reducing maintenance costs.

[0007] Optionally, the detachable upper panel further includes a first process plate and a second process plate. The first process plate is connected to the lower surface of the upper panel and is arranged along the other longer side of the upper panel. One end of the first process plate extends out of the upper panel and is welded to the side wall of the loading compartment. The second process plate is arranged vertically and is welded to the lower surface of the first process plate and the upper panel.

[0008] Optionally, the detachable upper panel further includes a third process plate, which is disposed on the lower surface of the lower panel where the first and second process plates are not disposed, and the upper end of the bow and stern sealing plates is welded to the lower surface of the third process plate.

[0009] Optionally, the first process plate and the third process plate are respectively connected to the upper panel using countersunk bolts. A fourth process plate is provided at the lower end of the countersunk bolts at the connection between the first process plate and the upper panel and at the connection between the third process plate and the upper panel. The fourth process plate is connected to the third process plate using countersunk screws.

[0010] By adopting the above technical solution, the first process plate is connected to the side wall of the loading compartment, and the second process plate is set to support the upper panel and the first process plate, so that the upper panel can be disassembled, which facilitates the maintenance of cables or pipelines in the internal space structure.

[0011] Optionally, the detachable upper panel, upper side panel, lower side panel, perforated diaphragm, and bow and stern sealing plate are all made of thin aluminum alloy sheets to meet the requirements of lightweight structure.

[0012] Optionally, the upper side plate is a right-angled plate, which includes a horizontal side plate and a vertical side plate. The horizontal side plate is connected to the upper panel using countersunk bolts, and a fourth process plate is welded to the upper side plate at the connection. The vertical side plate of the upper side plate is welded to the lower side plate.

[0013] Optionally, the lower side plate is a concave thin plate, and the cross section of the thin-walled box is an inverted trapezoid, which does not affect the arrangement of the loading deck mooring rails and mooring lashing.

[0014] Optionally, the perforated diaphragm is provided with round holes, which can reduce weight while meeting the requirements for the arrangement of ship cables and pipelines.

[0015] Optionally, the detachable upper panel is provided with a chamfered structure near the bow and stern sealing plates to ensure a gradual transition of the loading channel.

[0016] A loading hold includes two collision protection platform structures for the loading holds, which are arranged along the length of the ship. The perforated transverse bulkheads are welded to the side walls of the loading holds, and the bow and stern end plates and the lower side plates are welded to the loading deck.

[0017] In summary, the present invention has at least one of the following beneficial effects:

[0018] 1. This invention, by setting up a thin-walled box body composed of a detachable upper panel, upper side panel, lower side panel, perforated transverse partition and bow and stern sealing plate, and installing it in the loading compartment, can collide with the vehicle before the loading compartment side wall, cable pipelines, etc., and release the collision energy through its own flexible deformation. It can effectively prevent the vehicle from directly colliding with the loading compartment side wall and cable pipelines, thereby reducing damage to the loading compartment and cable pipelines and reducing maintenance costs.

[0019] 2. The cross-section of this invention is designed as a flexible inverted trapezoid, and the lower side plate is designed as a concave shape, so as not to affect the arrangement of the loading deck mooring rails and the mooring and binding.

[0020] 3. The present invention provides circular holes in the perforated bulkhead, which reduces weight while meeting the requirements for the arrangement of ship cables and pipelines, and alleviates the problem of limited space in the loading hold.

[0021] 4. The present invention is designed with a chamfered structure at the bow and stern ends to ensure a gradual transition of the loading channel.

[0022] 5. The present invention features a detachable top panel, which facilitates the inspection and maintenance of the internal space structure, cables, and pipelines.

[0023] 6. This invention can be used as a step leading from the loading cabin to the side cabins, facilitating personnel passage. Attached Figure Description

[0037] Example

[0038] In this embodiment, the upper panel 11, upper side plate 2, lower side plate 3, perforated transverse bulkhead 4, bow and stern sealing plates 5, and process plates are all made of 3mm thick aluminum alloy sheets. The overall height of the collision protection platform structure for the loading hold is 300-400mm, the upper width is 300-400mm, and the bottom width is 150-200mm. The collision protection platform structure for the loading hold is then symmetrically arranged on the port and starboard sides of the loading hold, located at the lower port and starboard corners of the loading hold and arranged along the length of the ship.
