Description

[Detailed description of the invention] The present invention relates to the structure of a container anchor used to stabilize cargo when stacking containers on a ship that does not have special equipment for loading containers. .

Usually, container ships are equipped with cell guides to streamline container loading operations and ensure stable stacking, but multi-purpose ships are not equipped with cell guides for containers.

For this reason, when loading containers onto ships that are not equipped with such container loading equipment, wires, chains,
Lashing work was carried out using rods, etc.

Therefore, it is not easy to stack cargo stably in a state that corresponds to the rocking of the ship, and it is also difficult to maintain the strength of the container when using rods or the like.

The purpose of the present invention is to solve the problems associated with conventional lashings, and to provide a container anchoring device that allows containers to be stably loaded even on ships that are not equipped with cell guides. be.

The locking device of the present invention utilizes the squeezing force between stacked containers to attach the locking device, connects the other end of this locking device to the hook of the hold wall, and furthermore inserts a wedge between the two. It is inserted to prevent movement.

As shown in FIG. 1, the proposed fastener 1 is a rectangular steel plate-like body with a square hole 11 formed on almost the entire surface except for one end, and the upper and lower surfaces of the end side. Same shape in symmetrical position,
A protrusion 12 of the same size is integrally formed.

Containers 4 are stacked in multiple stages in a ship's hold as shown in FIG. 2, but in the present invention, the stacking surfaces of the stacked containers 4 are used to clamp the locking tool 1 as shown in FIG. 3.

At this time, by holding the end portion of the locking tool having the protrusion 12 on the container side, the protrusion 12 fits into the recesses formed in advance on the bottom and top surfaces of the container 4, thereby ensuring a stable mounting state. is obtained and the other end protrudes laterally.

A square hole 11 is provided on the protruding side, and the hook part 3 of the hold wall is fitted into this square hole 11, and the tip side of this hook part 3 is
A wooden wedge 2 is driven into a square hole 11 where both side walls of the container are located and tightened.

Such locking portions are formed at each stacking portion as shown in FIG. 2, and also formed on symmetrical surfaces of the stack.

Therefore, the stacked containers are maintained in tension from both sides and fixed to the hold walls.

According to the locking device of the present invention, the lashing work of containers can be simplified and stable loading has become possible.

Moreover, it is possible to stack containers in multiple stages without using container rods, wires, chains, etc.
