のようなレールはない。 Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 to 4. 11 is a large hatch provided on the upper deck 14 of the hold 13 of the cargo ship 12, and 15 is a small hatch provided on the upper deck 14 adjacent to the large hatch 11 in the bow and stern direction. 16 is the large hatch cover of the above-mentioned large hatch 11, 17 is the small hatch 1
5 small hatch cover. The opening width of each of the hatches 11 and 15 is set to be 80% or more of the width of the ship, and therefore each of the hatch covers 16 and 17 has a structure in which the center part hardly flexes, that is, a box-shaped cross section with an arch shape. is being used. The large hatch cover 16 is sized so that the small hatch cover 17 can be accommodated in the lower surface of the large hatch cover 16, and the large hatch cover 16 is arranged on the large hatch 11 and on the small hatch 15. It is configured to be movable throughout. That is, a pair of rails 18, 18' are arranged on both sides of the large hatch 11 and small hatch 15, and two running wheels 1 are arranged on both sides of the large hatch cover 16.
9 is installed. Note that this running wheel 19
is rotationally driven by a rotary drive device 20 such as a hydraulic motor built into the large hatch cover 16. The large hatch cover 16 also has four holding devices 21 that can hold and release the small hatch cover 17.
It is set in place. That is, engagement holes 22 are formed at four positions on the upper surface of the small hatch cover 17, and the holding device 21 is connected to a first cylinder device 23 built in the large hatch cover 16.
and the rod 23a of this first cylinder device 23.
It consists of an engaging pawl 24 attached to the tip and detachably engaged with the engaging hole 22 of the small hatch cover 17. The engagement between the engagement claw 24 and the engagement hole 22 is achieved by inserting the engagement claw 24 into the engagement hole 22 and then rotating it through 90 degrees in a horizontal plane.
The first cylinder device 23 has a built-in mechanism for rotating the rod 23a by 90 degrees at its protruding position. By the way, large hatch cover 1
6 moves in the horizontal direction, so the large hatch 11
It is necessary to make the height position different when the door is closed and when it is open. Because when closed,
It is necessary for the sealing material 26 provided on the lower surface of the large hatch cover 16 to come into contact with and press the plate material 25 protruding from the upper surface of the coaming 11a of the large hatch 11, but when the large hatch cover 16 is opened, that is, when the large hatch cover 16 is moved. , the sealing material 26 must be separated from the plate material 25. Therefore, large hatch cover 1
6, the supporting portion rails 18a, 18'a of the running wheel 19 are partially cut off, and the second cylinder device 27 makes it possible to move up and down. Note that the small hatch cover 17 is raised and lowered by the large hatch cover 16, so there is no rail as described above.
次に、各ハツチの開閉動作について説明する。 Next, the opening and closing operations of each hatch will be explained.

分で済み、非常に経済的である。 First, when opening the large hatch 11, as shown in FIG.
Separate the sealing material 26 from the plate material 25 on the side 1a, and then attach the large hatch cover 16 to the small hatch cover 17.
Just move it up. Next, when opening the small hatch 15, as shown in FIG.
7, the first cylinder device 23 is operated to insert the engaging claw 24 into the engaging hole 22 of the small hatch cover 17 and rotate the engaging claw 24 by 90 degrees. Next, the first cylinder device 23 is operated again to pull up the small hatch cover 17 and hold it on the lower surface of the large hatch cover 16. In this state, the large hatch cover 16 may be moved onto the large hatch 11. In addition, each hatch 11, 15
If you want to close it, just follow the steps in reverse to the above. In this way, since the large hatch cover 16 is used to open and close the small hatch cover 17, only one traveling device and rail are required for the hatch cover, which is very economical.
