Technical Field

[0001] The utility model relates to the technical field of bulk carriers, in particular to a hatch cover mechanism for propelling bulk carriers. Background Art

[0002] For bulk carriers, cargo hold hatch covers are often covered with soft materials such as tarpaulins and fastened on both sides with special ship straps. This method is relatively traditional and requires manual labor to untie the straps when opening or closing, which is labor-intensive and time-consuming. In addition, some hatch covers are large in size and weight, making it inconvenient for workers to carry, open and close them, and posing certain risks. Therefore, a hatch cover mechanism for propulsion of bulk carriers is needed to improve the above problems. Utility Model Content

[0007] The hatch cover is provided with an adjustment mechanism, which includes a screw. Two first mounting plates are symmetrically fixedly installed on the hatch cover, and the two first mounting plates are connected by a second mounting plate. An L-shaped plate is fixedly installed on the outer wall of the cabin, and the first fixing plate is fixedly installed on the L-shaped plate. One end of the screw passes through the first fixing plate and is rotatably connected to the bottom end of the L-shaped plate. A moving block is screwed on the screw. Two hinged seats are symmetrically fixedly installed on the moving block and the second mounting plate. The corresponding two hinged seats are rotatably connected by a connecting rod.

[0008] The moving block is limited by a limiting mechanism. The limiting mechanism includes two limiting rods. The two limiting rods are symmetrically fixed on the first fixed plate. Two sliding holes are symmetrically opened on the moving block. The two limiting rods are slidingly connected to the two sliding holes respectively. The two limiting rods are connected by a connecting plate, and the connecting plate is rotationally connected to the screw.

[0009] Preferably, a second fixing plate is fixedly mounted on the L-shaped plate, and the second fixing plate is rotatably connected to the screw rod.

[0010] Furthermore, a reinforcing plate is fixedly mounted on the L-shaped plate, and the other end of the reinforcing plate is in contact with the second fixing plate.

A rotating shaft 3 is rotatably installed on the hatch cover 2. Slide blocks 4 are fixedly installed at both ends of the rotating shaft 3. Slide grooves are opened on the inner side walls at both ends of the cabin outer wall 1. The two slide blocks 4 are respectively slidably connected to the slide grooves. When the hatch cover 2 moves, the two slide blocks 4 slide on the cabin outer wall 1 respectively, so that the hatch cover 2 is more stable when moving.

[0024] See also Figure 1-4 , an adjustment mechanism is provided on the hatch cover 2, which includes a screw 9. Two first mounting plates 5 are symmetrically fixedly installed on the hatch cover 2, and the two first mounting plates 5 are connected by a second mounting plate 6. An L-shaped plate 7 is fixedly installed on the outer wall 1 of the cabin, and a first fixing plate 8 is fixedly installed on the L-shaped plate 7. One end of the screw 9 passes through the first fixing plate 8 and is rotatably connected to the bottom end of the L-shaped plate 7. A moving block 10 is screwed on the screw 9, and two hinge seats 11 are symmetrically fixedly installed on the moving block 10 and the second mounting plate 6. The corresponding two hinge seats 11 are rotatably connected through a connecting rod 12. By rotating the screw 9, the moving block 10 is moved on the screw 9, and the cooperation of the two connecting rods 12 drives the second mounting plate 6 to move, thereby driving the hatch cover 2 to move, thereby opening the hatch cover 2 and releasing the hatch cover 2 from blocking the outer wall 1 of the cabin.

[0025] See also Figure 1 、 Figure 2 and Figure 4 The moving block 10 is limited by a limiting mechanism. The limiting mechanism includes two limiting rods 13. The two limiting rods 13 are symmetrically fixed on the first fixed plate 8. Two sliding holes are symmetrically opened on the moving block 10. The two limiting rods 13 are slidably connected to the two sliding holes respectively. The two limiting rods 13 are connected by a connecting plate 14, and the connecting plate 14 is rotatably connected to the screw 9.

[0026] See also Figure 1 and Figure 2 A second fixing plate 15 is fixedly mounted on the L-shaped plate 7, and the second fixing plate 15 is rotatably connected to the screw rod 9. The arrangement of the second fixing plate 15 makes the screw rod 9 more stable when rotating.

[0027] See also Figure 1 and Figure 2 A reinforcing plate 16 is fixedly mounted on the L-shaped plate 7, and the other end of the reinforcing plate 16 is in contact with the second fixing plate 15. The installation of the reinforcing plate 16 makes the second fixing plate 15 more stable, thereby making the screw 9 more stable.

[0028] See also Figure 2 It should also be noted that a stabilizing cylinder 17 is fixedly installed at the bottom end of the L-shaped plate 7, and the screw 9 is rotatably connected to the stabilizing cylinder 17. The installation of the stabilizing cylinder 17 makes the screw 9 more stable when rotating.

[0029] See also Figure 1 and Figure 2 A hand wheel 18 is provided on the screw rod 9, and the setting of the hand wheel 18 facilitates the rotation operation of the screw rod 9.

[0030] In summary, when the hatch cover mechanism of the propulsion bulk carrier is in use, the screw 9 is rotated by the handwheel 18, so that the moving block 10 is limited on the screw 9 by the two limit rods 13, and the second mounting plate 6 is driven to move by the cooperation of the two connecting rods 12, thereby driving the hatch cover 2 to move. While the hatch cover 2 moves, the two sliders 4 are respectively slid on the outer wall 1 of the cabin, so that the hatch cover 2 is more stable when moving, thereby opening the hatch cover 2 and removing the hatch cover 2 from blocking the outer wall 1 of the cabin.
