Description

technical field [0001] The invention relates to a method capable of improving the utilization rate of space in a container ship, in particular, the hatch cover can be freely crossed to meet the standard container transportation, and is also suitable for the transportation of non-standard containers. It is a method that can provide container ships method of loading rate. In addition, the present invention also relates to a container ship fastening device, which is a fastening device installed on a container ship, which can be used not only for standard container transportation, but also for non-standard container transportation. Suitable for different ship types. Background technique [0002] At present, the length of the monument (BAY) on most operating standard container ships is the length of the ISO standard 20-foot or 40-foot container, and there are a few ships with a small number of 45-foot or 53-foot monuments on the fore and aft deck areas, but It is far from meeti...

Problems solved by technology

[0005] In order to adapt to the transportation of non-standard containers, the transfer beams, transport frames, transport platform units, and transfer boxes of specific box types can be transported on local areas of a specific ship type such as decks, hatch covers, and standard containers in the market. The disadvantage is that there are additional logistics costs such as return transport and stacking, and the operation process is cumbersome, and different ship types or different loading areas on the ship and box types of different sizes need to be re-customized as a whole or partially, and there are limitations in use and circulation. :

[0006] Chinese patent CN2851101Y provides a detachable multi-modal transportation mechanism. In this prior art, the fixing between the lock seats on the first layer is completed through the connection of the lock seat buckles, and the length of the lock seat buckles needs to be determined according to different The recalculation, customization and replacement of ship and box types also increase the operation and time costs of ship loading and unloading, and when the ship is tilted vertically and horizontally due to wind and waves, the connection between the movable lock seat and the non-standard container is easy to be performed in multiple groups of superimposed non-standard containers. The fastening fails under the action of the gravity of the container and its sliding inertial force, which poses a safety hazard; in addition, the lock seat needs to be replaced when the non-standard container and the standard container are loaded and switched, otherwise the bottom beam at the front and rear ends of the standard container and the non-standard container will be pushed up by the lock head It cannot be put down, the operation is complicated and fragile

[0007] Chinese patent CN2883170Y provides a conversion beam for shipping ultra-wide containers. In this prior art, the length of the conversion beam is based on a certain hatch cover, and cannot be placed across the hatch cover. The utilization rate of the ship's space is not high. Taking 5 standard containers or 4 non-standard containers side by side on one hatch cover as an example, the space utilization rate of the conversion beam is 80%, because the center distance of each group of corner fitting holes corresponding to the standard container at the top and bottom of the conversion beam is 2260mm The adjacent spacing between the hole positions is fixed, which makes it unsuitable for ships with different sizes of hatch covers or different spacings of container corner fittings on adjacent compartments, because each group of holes on the top corresponds to 2591mm in the width direction of non-standard containers The fixed position limits its applicability to non-standard containers of different widths, and requires separate hoisting, stacking and return transport

[0008] Chinese patent CN100482551C provides a platform for transporting ultra-wide containers and a transport unit composed of multiple transport platforms, but the same problem exists in this prior art, the corner fittings used to connect non-standard containers on the platform transport unit The position on the transom is fixed, and the same platform transport unit is not suitable for ship types with different hatch cover spacing and different adjacent corner fitting seat spacing, nor for non-standard containers of different widths or different corner fitting center distances , all need to be recalculated and customized; the transport platform unit has limitations for different container ships and non-standard containers

[0009] Chinese patent CN201224482Y provides a combination frame for transporting ultra-wide containers. The center distance of a single group of cargo connectors in the prior art is fixed, and the distance between two groups of cargo connectors is also fixed, resulting in its It is not suitable for ship types with different spacing between hatch covers of different sizes / corner fitting seats on adjacent compartments, and limits its applicability to non-standard containers of different widths, and needs to be collected, hoisted, stacked and returned separately

[0010] Chinese patent CN103144870B provides a container adaptability conversion mechanism. In order to cope with different ship types and different sizes of containers, the length of the plate-packing spacing limit sleeve connected to the movable fillet needs to be re-customized and replaced, which increases the time required for loading and unloading the ship. In addition, the movable fillets on the beams can only move in one direction laterally, but they cannot offset the failure caused by the longitudinal displacement of different hatch covers caused by wind and waves, which will cause problems for non-standard containers placed above this area. In addition, due to the over-length limitation of the beam length of 2600 mm, normal dense loading of standard containers cannot be resumed after the non-standard container transportation is completed, resulting in additional collection stacking and return costs

[0011] Chinese patent CN203497379U provides a container transport frame, which solves the applicability to different ship types by adjusting the length of the extension frame and the distance of the conversion corner piece, but the operation is cumbersome and requires recalculation and customization. The total length of the frame is at least greater than 40 feet Standard containers, which means that the shipping frame cannot be loaded in the cargo hold of a container ship. It still needs to be stacked and stored when non-standard containers are not carried, which takes up space and increases logistics costs. In addition, there is also the problem of loading non-standard containers on ships There are limitations in the applicability of the extension frame. The design of the conversion corner fittings on the extension frame does not consider the longitudinal displacement between the hatch covers, which is easy to be damaged.

[0012] Chinese patent CN203946458U provides an ultra-wide box transport girder. In this prior art, the same transfer beam is not suitable for ships with different hatch cover spacing and different standard container corner fitting seat spacing. The same conversion beam is suitable for different widths or different angles. The non-standard container with the center distance of the parts is also not applicable. In addition, the conversion beam needs additional separate hoisting, and comprehensive logistics costs such as stacking and returning
