Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a lashing platform for open container ships. Background Technology

[0002] River-sea direct open-top container ships are a type of high-efficiency transport vessel designed specifically for river-sea direct routes. The open-top design eliminates the need for traditional hatch covers, which not only reduces the weight of the hull and improves the utilization rate of cargo hold volume, but also facilitates the rapid loading and unloading of containers and shortens port dwell time.

[0003] In order to continue to highlight the advantages of open-top container ships that can directly cross rivers and seas, such as lower hull weight, improved loading and unloading efficiency, and shorter ship length, the design of existing open-top container ships that can directly cross rivers and seas has eliminated the design of traditional container ship lashing bridges.

[0004] Although the related technology has eliminated lashing bridges, the requirements for container lashing have not been reduced. After loading is completed, bridge locks are still required to connect adjacent containers on top. Due to the lack of hatch covers and lashing bridges, crew members must use ladders or climb directly to carry the necessary locks to the top of the containers for securing during container loading and unloading operations. Furthermore, some vessels are not equipped with fully automatic twist locks, requiring crew members to install or remove twist locks from the top of containers during loading and unloading. The lack of fixed climbing equipment significantly increases the operational risks for crew members.

[0005] Therefore, it is necessary to develop a new type of lashing platform for open container ships to improve some of the problems existing in the relevant technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a lashing platform for open container ships, which allows crew members to climb and lash the containers safely and reliably, reducing the risk of falling. Furthermore, the lashing platform can be quickly and easily attached and detached from the ship's hatch, improving the lashing efficiency of container ships without affecting the loading and unloading efficiency and high container capacity of open container ships that operate directly between river and sea.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] This invention provides a lashing platform for open container ships, comprising: a working layer, a supporting structure, a climbing passage, a spreader assembly, and a connecting structure; at least two working layers form a working space for personnel to perform container lashing operations at different heights; the supporting structure connects the working layers, arranging them vertically; the climbing passage connects adjacent working layers, allowing personnel to move between working spaces; the spreader assembly is disposed on the supporting structure for lifting and transporting containers to the top of the bulkhead of the ship's hold using a lifting device; the connecting structure is disposed at the bottom of the supporting structure, connecting the supporting structure to the top of the bulkhead.

[0009] Furthermore, the support structure includes a plurality of columns arranged in a rectangular shape in the horizontal plane to match the surface of the top of the bulkhead.

[0010] Furthermore, the column is made of angle steel, and the material of the angle steel is carbon structural steel, grade B.

[0011] Furthermore, the connection structure includes a diagonal brace, the end of which is connected to the support structure and the top of the bulkhead, and the angle between the diagonal brace and the column is greater than or equal to 45° and less than or equal to 75°.

[0012] Furthermore, the connection structure also includes fasteners for fixing the support structure, the fasteners including any one or more of studs, bolts, rivets, and anchors.

[0013] Furthermore, the climbing passage includes a foot hole and a ladder disposed in the floor of the working layer, the ladder passing through the foot hole, and the floor material being fiberglass.

[0014] Furthermore, the ladder is formed by welding steel profiles, and the material of the steel profiles is ferritic-bainitic steel.

[0015] Furthermore, the lifting device assembly is any one or more of a shackle, a shackle, or a sling.

[0016] Furthermore, the working layer includes a floor and guardrails, the guardrails having a multi-layered structure in the height direction, and the guardrails in the same layer being connected by detachable chains.

[0017] Furthermore, a pedestrian opening is provided on the floor, which is located at the first and second side edges of the floor along the length of the floor. A ladder passes through the pedestrian opening vertically through the floor of a working level.

[0018] Compared with existing technologies, the beneficial effects of the lashing platform for open container ships provided by this invention are as follows: This invention supports at least two working levels through a support structure, forming at least two working spaces. Adjacent working levels are connected by climbing passages, allowing workers to move and lash containers within working spaces at different heights. This not only meets the lashing requirements of different deck heights but also significantly reduces the risk of falls during climbing, improving lashing efficiency. Furthermore, since the support structure also includes spreader components and connecting structures, shore-side workers can pre-assemble the lashing platform before the open container ship docks for loading and unloading. Using lifting equipment and spreader components, the pre-assembled lashing platform can be quickly transported to the top of the ship's bulkhead, and reliably connected and fixed to the top of the bulkhead via the connecting structures. This further shortens construction time, improves the ease of installation and disassembly of the lashing platform, and the removal of the lashing platform after lashing does not affect the container ship's carrying capacity.
