Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for transshipping large solid cargo such as containers, plants, or vehicles and bulk cargo such as grain, ore, or coal at any time depending on the route on a ship, especially a multipurpose cargo ship. The present invention relates to the structure of a lashing fitting set that is extremely effective when used as a lashing fitting on the surface of a loading structure on a ship that needs to be secured.

Loading structure surfaces include, for example, the surfaces on tank tops, decks, hatch covers, etc.

The problem with this type of multi-purpose cargo ship is that when loading solid cargo, lashing metal fittings must be set on the surface of the loading structure, and as a result, the metal fittings protrude from the top of the tank. When switching to bulk cargo, these metal fittings should be removed and the tank top should be made flat to avoid impact from grabs and pressure inspection by bulldozers, which provides flexibility.

First, to introduce the various systems of incomplete lashing metal fittings that have been used in the past, the first type is the convex type shown in Figure 5, with slots (5A and 5B), slide guides ( 5C, 5D), corner bracket) (5E,
5F) or cloverleaf (5G, 5
A receiver such as the one shown in Figure B) has metal fittings welded onto the tank top in a convex shape, and is used by attaching and removing the metal fittings.

The second type is a concave type as shown in Fig. 6 (Figs. 6A to 6), in which a recessed type washer is welded to the surface of the structure and a lashing fitting is attached and detached.

However, in the case of the above-mentioned convex type (Fig. 5), the lashing metal receiver may be damaged by equipment such as a grab or a bulldozer, or may interfere with cargo handling operations, and in the case of a folding type cargo hold. , which interferes with retraction of the palate.

In addition, except for the cloverleaf cone, the strength structure of the upward lashing cannot be achieved, and it takes time and effort to use removable metal fittings and to store and transport.

In addition, in the case of the concave type (Figure 6), the above-mentioned problems of the convex type are solved, but on the other hand, the recess may be clogged with remaining bulk cargo, or rainwater or washing water may enter. Particularly in cold regions, the residual water freezes, making the lashing fittings impossible to attach and detach, causing problems in the industry, such as hindering work.

As a desperate measure to prevent the intrusion of such foreign substances, residual water, and so-called impurities, the filling method shown in Figure 7 is used as the third category, and the container is covered with a separate cap or filled with stuffing. The current situation is to prevent the entry of the above foreign substances, but this method still has various problems such as high cost, inconvenient work, corrosion of the cap screw, and deformation of the filling. It is.

Therefore, the applicant has devised the present invention to solve the above-mentioned drawbacks.

That is, the object of the present invention is to provide a state in which a lashing metal fitting is stably set in a curved state on a smooth surface and a state in which the metal fitting is removed and restored to a smooth state by using an extremely simple configuration and operation. A lashing metal fitting that can be realized very easily and quickly, and that has no risk of contaminants entering into the recesses of the metal fitting, and also that there is no risk of falling off or loss of the members constituting the device. Our goal is to provide the following.

Another object of the present invention is to provide a lashing metal fitting set that can be applied to many types of lashing metal fittings and can exert a hooking force even as an upward lashing.
