  Referring to FIG. 4, a conical locking protrusion 21a is formed at the bottom end of the rotating protrusion 21 and extends radially and has an inclined surface 21b on the bottom surface.

  On the fixed base portion 10 corresponding to this, there is provided a lock unit 12 in which a locking tip portion 12a for locking the locking projection 21a to prevent detachment is formed.

  In the lock unit 12, a hinge shaft 12 b prepared on the adjacent portion of the locking tip portion 12 a, that is, on the upper side of the lock unit 12 is hinged to the inside of the fixed base portion 10 that is adjacent to the insertion hole portion 11. It has a rotating shaft structure.

  The locking tip 12a is formed in a protruding shape protruding in the direction of the rotating protrusion 21.

  When the rotating projection 21 is inserted into the insertion hole 11, the locking tip 12a is pushed by the inclined surface 21b at the lower end of the rotating projection 21 and rotates in the clockwise direction with respect to the hinge shaft 12b. A rotation protrusion 21 is inserted by forming a space.

  That is, when the rotary protrusion 21 of the rotary base 20 is inserted into the insertion hole 11 of the fixed base 10, the locking tip 12 a of the lock unit 12 is pushed against the inclined surface 21 b of the lower end of the rotary protrusion 21.

Then, the loading of the container 7 is completed by being applied to the frame portion inside the through hole 7b.

  On the other hand, after the rotary base 20 connected to the fixed base 10 is separated from the fixed base 10, the separated rotary base 20 is attached to each edge connection 7 a of the container 7. It is also possible to load the container 7 in such a manner that the rotating base 20 connected to the edge connecting portion 7a is connected to the fixed base 10 in a directly connected state.

  In this case, the locking tip 12a is rotated backward via the lever 12c of the lock unit 12 of the fixed base 10 to release the locking protrusion 21a, and the rotating protrusion 21 is detached from the insertion hole 11. Can be made.

  On the other hand, when the container 7 is to be loaded and unloaded in-hold in a state where the rotating base part 20 is connected to the fixed base part 10, the rotating base part 20 is axially rotated to the side to rotate the container. Do not interfere with the up-and-down movement of 7.

  When the container 7 is to be released, the rotating lever 22b is operated so that the container 7 is separated into the rotating base portion 20, and the lever 12c of the lock unit 12 is operated to fix the fixed base portion 10. The rotating base 20 is separated from the base.

  As described above, the embodiment of the present invention includes the fixed base portion 10 fixed to the hull 5 and the rotary base portion 20 that is coupled to the fixed base portion 10 so as to be axially connected and detachable. By using an underlay structure that supports only the bottom four edges of the container 7, the total weight is basically greatly reduced and the power energy of the container ship can be reduced. This eliminates the risk of cost burden and fatigue damage due to the fitting of the hatch cover, and also eliminates the problems of the transportation and cargo handling system operated in units of hatch covers.
