Description

  The present invention relates to a container ship that transports a large number of containers stacked in multiple stages, and more particularly, to a container ship that includes means for securing a larger number of containers stacked in multiple stages.

Conventionally, a large number of containers are stacked and transported by ship in a conventional manner. In shipping such containers, a large number of containers are stacked in the hold and on the deck. Since the containers stacked in the hold are supported by the cell guide, they have good stability and do not require lashing.
On the other hand, the container stacked on the deck tilts the container stacked by the left and right shaking of the hull, and the tilt changes the position where the upper container pushes down the lower container. If the container is deformed and greatly deformed, the container may be damaged.
In addition, the deformation of the container into a rhombus is called racking. In order to prevent the racking, the containers stacked on the deck are stabilized by ordinary lashing.

As a conventional technique related to a shipboard container securing technique, a “locking rod device for a container ship” is described in Japanese Patent Publication No. 11-502484 (Patent Document 1).
The container bridge for a container ship described in Patent Document 1 includes a second lock hole disposed substantially at the same height as the first lock hole, and the second lock rod is The container is held by extending in a substantially horizontal direction from the second locking hole, and the first locking rod is fixed to the container disposed in the upper stage stacked in the upward direction from the first locking hole. .

Engage with the lower concave portion of the third stage of the stacked container, tie it with a turnbuckle, and have a second locking hole arranged at substantially the same height as the first locking hole, From there, the second locking rod is extended substantially horizontally in the horizontal direction, and engaged with the upper recess of the lower container (the second stage of the container stacked as viewed from above the hatch cover), and at the turnback Tie up.
According to the first locking rod, it is disclosed that the stacked containers can be stabilized, and according to the second locking rod, a heavy object can be carried.

In addition, as a conventional technique related to a shipboard container lashing technique, “shipboard container lashing apparatus” is described in Japanese Patent Application Laid-Open No. 2000-335480 (Patent Document 2).
In the onboard container tying device described in Patent Document 2, one end of a fastening member including a lashing rod and a turnbuckle is attached to a lashing eye plate of a lashing pillar erected on the ship, and the fastening member extends obliquely downward. The other end is attached to the corner metal of the container, and is tightened so that a component of force is generated in the direction of lifting the container.
Accordingly, it is disclosed that the compressive force at the corner of the container can be reduced, the collapse can be prevented, and the fastening member can be reduced in size and weight.

Furthermore, “container lashing method” is disclosed in Japanese Patent Application Laid-Open No. 2002-321686 (Patent Document 3) as a conventional technique relating to a shipboard container tying technique.
In the container securing method described in Patent Document 3, a plurality of containers are stacked between lashing bridges provided on the deck, and the lower surface of the container is held at substantially the same level as the upper surface of the lashing bridge. Engage one end of a tie that can be extended and contracted with the corner fittings at the bottom of both ends, and connect the other end of the tie to the upper part of the lashing bridge. The metal fittings are secured horizontally, and the adjustable fasteners are placed on one side of the container between the corner metal fittings at the bottom of both ends and the upper part of the lashing bridge in the next container on the horizontally secured container. The two fasteners are crossed diagonally so that they cross each other, and the lower corner fittings of the container in the next stage are tied diagonally by tightening each of the fasteners. This increases the support rigidity of the corner, eliminates the need for securing work in the uppermost container of a plurality of containers stacked on the corner, shortens container securing time, and reduces worker fatigue. It is disclosed that it is possible to measure.
