Description

Technical Field

[0001] The utility model relates to the technical field of ribbed plates for oil tankers, in particular to a ribbed plate for a corrosion-resistant superstructure of an oil tanker. Background Art

[0002] Oil tankers are ships specially used to transport oil and its products. Oil pumps are used to load and unload cargo through pipelines, so there are no cargo lifting equipment and large cargo hatches on the deck, but there are entry hatches. Since oil is easy to evaporate, burn and explode, strict fire safety requirements are imposed. The 1978 Protocol of the International Maritime Organization stipulates that new oil tankers with a deadweight of more than 20,000 tons must have inert gas explosion-proof facilities and the engine room must be located at the stern.

[0003] In the manufacturing process of oil tankers, corrugated plates are used in their superstructures. The structure of corrugated plates has the characteristics of light weight, high bearing capacity, strong bending resistance, and small space occupation. After reasonable design, they can play the role of support, protection, and structural connection, etc. They are widely used in aerospace, shipbuilding, automobiles, construction, energy, transportation and other fields. At the same time, due to the influence of the use environment of oil tankers, their corrugated plates need to have strong corrosion resistance.

[0004] For example, a side reinforcement structure with application number 201910695890.5 uses a ribbed plate instead of a welded structure. The increased strength brought by the groove structure on the ribbed plate replaces the conventional reinforcement method of welding ribs on the metal plate, which greatly reduces manual welding and grinding operations, saves construction costs, and improves construction efficiency. In addition, the ribbed plate also has a stretchable property in the length direction, so that the ribbed plate can be fine-tuned in the length direction for easy assembly, but its device still has certain defects;

[0005] The corrugated plates are not provided with an anti-corrosion structure, which will accelerate the corrosion of the corrugated plates during the use of the oil tanker, thereby reducing the service life of the corrugated plates and making it inconvenient to splice the corrugated plates.

[0006] Therefore, we propose a corrosion-resistant ribbed plate for oil tanker superstructure to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of the utility model is to provide a corrosion-resistant corrugated plate for an oil tanker superstructure, so as to solve the problem raised by the above-mentioned background technology that the corrugated plates on the current market are not provided with an anti-corrosion structure, which will accelerate the corrosion of the corrugated plates during the use of the oil tanker, thereby reducing the service life of the corrugated plates, and at the same time it is inconvenient to splice the corrugated plates.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corrosion-resistant ribbed plate for a superstructure of an oil tanker, comprising a first ribbed plate body, a second ribbed plate body, a first arc block and a second arc block, the second ribbed plate body is arranged on the right side of the first ribbed plate body, and the first arc block is installed on the right upper surface of the first ribbed plate body, the second arc block is installed on the left upper surface of the second ribbed plate body, arc grooves are opened inside the first arc block and the second arc block, a connecting plate is installed above the first arc block, and a second fixing bolt is installed on the connecting plate;

[0013] Preferably, both left and right sides of the first arc block and the second arc block are provided with through grooves, and the width of the through grooves is greater than the diameter of the connecting rod, and the width of the through grooves is less than the thickness of the anti-slip head and the semicircular block.

[0014] By adopting the above structural design, the connecting rod can move inside the first arc block and the second arc block, so that it is convenient to pull the connecting rod through the anti-slip head to drive the semicircular block to rotate.

[0015] Preferably, the connecting plate is designed as an inverted "L"-shaped structure, and a threaded structure is formed between the connecting plate and the second fixing bolt, and the diameter of the second fixing bolt is equal to the distance between the first arc block and the upper semicircular block of the second arc block.

[0016] With the above structural design, when the two semicircular blocks are rotated to a vertical direction, the second fixing bolt is rotated, and the second fixing bolt moves downward along the connecting plate, so that the second fixing bolt moves into the gap between the two semicircular blocks, thereby limiting the two semicircular blocks and preventing them from rotating.

[0017] Preferably, the anti-slip head is fixedly connected to the connecting rod, and the outer surface of the connecting rod is provided with anti-slip grooves.
