Description

Fastening unit and fastening device for container ship

Technical Field

The utility model relates to a container ship fastening unit, fastener, concretely relates to install on container ship, not only can be used for the fastening unit, the fastener of standard container transportation, but also can be used for the fastening unit, the fastener of non-standard container transportation.

Background

Currently, the length of the monument (BAY) on most operating standard container ships is 20-foot or 40-foot ISO standard containers, and a few bow and stern deckboard areas on a ship are also provided with a few 45-foot or 53-foot monuments, but far from meeting the transportation requirements of non-standard containers or containers.

The monument is an area divided along the longitudinal direction of the ship, the same monument can be used for placing N rows of containers side by side, the line is an area divided along the width direction of the ship, the layer is an area divided according to the upper space and the lower space of the ship, and the cabin is a space for loading a single standard container, for example: the 20 nd stele, the 2 nd row, the 70 th layer, is the position of the 20 th stele in the ship length direction, namely the position of a standard container at the 70 th layer height in the 2 nd box counted from the ship side, if the position is the 16 th stele, namely a row of containers placed at the position of the 16 th stele area in the ship length direction along the ship width direction, four groups of standard container corner piece seats are arranged on the positions of a bottom plate, a deck and a cover in the cargo hold, the adjacent interval of each group of corner piece seats is designed according to the ship type, the size of the cover and the gap of the cover, the interval of the corner piece seats on different covers is different, and the interval between the adjacent covers of different ship types is also different.

By non-standard container is meant a container that is not a standard size in length or width, or both, i.e., a width that is different from the 2438 mm width specified for ISO standard containers, or a corner fitting center-to-center spacing that exceeds 2260 mm, typically including 40/45 feet for european boxes 2500 mm wide and 53 feet for us boxes 2600 mm wide; or containers having a length different from the ISO standard 20-foot or 40-foot container length, such as 10/24/24.5/30-foot standard boxes, as well as house boxes, equipment boxes, offset ocean platform boxes, and miscellaneous tanks, and the like, all of which have different lengths and widths.

In order to adapt to the transportation of non-standard containers, the transportation of transfer beams, transportation frames, transfer boxes of specific types among them can be realized on local areas of a specific ship type such as decks, hatches, standard containers, for example:

chinese patent CN2851001Y provides a detachable multi-type intermodal transport mechanism, in this prior art, the fixation between the first-layer lock holders is completed by the connection of the lock holder buckle sleeves, the length of the lock holder buckle sleeves needs to be recalculated, customized and replaced according to different ship types and box types, the operation and time cost during loading and unloading of the ship are also increased, and the damage caused by the longitudinal displacement of the hatch cover is not considered.

Chinese patent CN201224482Y provides a combined frame for transporting ultra wide containers, where the center distance of the single set of cargo connectors is fixed and the distance between the two sets of cargo connectors is also fixed, making it unsuitable for use with different sizes of hatches/different distances between container corner fittings on the hatches, and limiting its applicability to different widths of non-standard containers, and requiring separate collection, lifting, stacking and return shipping.

Chinese patent CN103144870B provides a container adaptability switching mechanism, which needs to be customized and replaced again to deal with the length of the spacing sleeve between the plate-loading and the box-loading of the containers with different ship types and different sizes, which increases the operation and time cost when loading and unloading the ship, in addition, the movable fillet on the cross beam can only do transverse unidirectional movement and can not counteract the failure caused by the longitudinal displacement of different hatchcovers caused by wind waves.

Chinese patent CN103241478B provides a container, and this transfer box among the prior art can realize the sea transportation to 53 feet super wide (2600 mm) case on appointed ship, but the same transfer box can't dock the nonstandard container that has different corner fitting hole centre-to-centre distances in container width direction, and its suitability to different ship types and different box types has the limitation, and this type of transfer box still has extra comprehensive logistics cost problems including piling up deposits, THC hoist and mount etc..

Chinese patent CN2883170Y provides a transfer beam for shipping ultra-wide containers, where the length of the transfer beam in the prior art is in terms of a hatch cover, and the transfer beam cannot be placed across the hatch cover, and because the adjacent distance between the hole sites corresponding to 2260 mm in the center distance of the standard corner fitting holes in each group of the top and bottom of the transfer beam is fixed, it is not suitable for the different sizes of hatches or the ship types with different distances between the corner fitting seats of the container on the hatch cover, and because the hole sites corresponding to 2591 mm in the width direction of the non-standard container in each group of the top of the transfer beam are fixed, the applicability of the transfer beam to the non-standard containers with different widths is limited, and the transfer beam needs to be lifted, stacked and transported back separately.

Chinese patent CN100482551C provides a platform for transporting ultra wide containers and a transportation unit composed of multiple transportation platforms, but the prior art has the same problems, the position of the corner piece on the beam for connecting the non-standard container on the platform transportation unit is fixed, the same platform transportation unit is not suitable for the ship type with different deck lid spacing and different adjacent corner piece seat spacing, and is also not suitable for the non-standard container with different width or different corner piece center distance.

Chinese patent CN203497379U provides a container transportation frame, which solves the problem of applicability to different ship types by adjusting the length of the extension frame and the distance between the corner pieces, but has the disadvantages of complex operation, need to recalculate and customize, still has the problems of need to stack and store when not carrying non-standard containers, space occupation and increased logistics cost, and in addition, has the limitation to the applicability of ship loading non-standard containers, and the design of the corner pieces on the extension frame does not consider the longitudinal displacement between the covers, and is easy to damage.

The main drawbacks of the above mentioned prior art patents are: the logistics cost of additional return transportation, stacking and the like is needed, the operation process is complicated, and the whole or local customization is needed for different ship types or different loading areas on ships and boxes with different sizes, so that the use and circulation limitations exist.
