The hatch cover 110 is provided in a rectangular plate shape to selectively align the hatch, lift, exhaust, and the like of the ship. In addition, the hatch 110 can be adjusted in thickness as needed. A plurality of locking bar support bars 111 that support the locking bars 160 up and down are formed in the up and down direction at the front of the hatch 110.

The hatch frame 120 has a rectangular frame shape for supporting the hatch cover 110. On the left side of the hatch frame 120, there is provided a coupling shaft for rotatably coupling the side guide bars 150, and on the lower side of the hatch frame 120, a locking groove 122 is formed which is combined with the locking bar 160 to function as a locking function. . The locking groove 122 may be directly formed in the hatch frame 120, or as shown in FIGS. 1 to 9, an additional locking frame 121 is formed at the central lower end of the hatch frame 120 and a locking hole is additionally formed in the locking frame 121. 122. In addition, in the first figure and the second figure, the shape and the set position of the lock frame 121 are schematically shown in the shape of the plate, but actually, as shown in Fig. 4, the locking bar 160 may be locked on the left and right. Between the side plates, a locking step structure is provided on the front side of the locking groove 122.

The hatch hinge 130 is provided on the upper side of the hatch 110 and the hatch frame 120 and is combined to rotate the hatch 110 forward relative to the hatch frame 120.

The opening protrusion 140 protrudes laterally from one of the left side surface or the right side surface of the hatch cover 110 (the left side surface in one embodiment of the present invention), and is rotated forward in conjunction with the opening motion of the hatch cover 110.

The side guide bar 150 is provided with a plate shape extending in the up-and-down direction, and the lower end portion is rotatably coupled to one side surface of the hatch frame 120, and a long hole-shaped guide hole 151 is formed along the side surface, and the upper portion of the guide hole 151 is further rearward. The side is extended to form a support step 152 to engage with the opening protrusion 140 to open and close the hatch cover 110 and to fix the open state of the hatch 110.

As described above, in the hatch cover device for a ship according to the embodiment of the present invention, the rice-opening projection 140 provided in the hatch cover 110 and the side guide bar 150 provided in the hatch frame 120 are coupled to each other, and are guided by the open projection 140. The movement characteristics of the sliding movement of the hole 151 easily guide the opening and closing operation of the hatch 110 with respect to the hatch frame 120, and the open state of the hatch 110 can be easily fixed.

In addition, the hatch cover device for a ship according to an embodiment of the present invention may further include: a locking strip 160 extending in front of the hatch cover 110 to move in the up and down direction, and a lower end portion being coupled to the center of the lower frame formed in the hatch frame 120. The locking groove 122 locks the hatch 110 to the hatch frame 120; and the torsion spring 170 is provided to the hatch hinge 130 to provide an elastic reaction force to open a portion of the hatch 110 when the locking bar 160 moves upward to unlock .

As described above, when the lock bar 160 releases the lock of the lock bar 160 in a state where the elasticity of the torsion spring 170 is suppressed, a part of the high-weight hatch cover 110 can be pushed forward by the momentary elastic reaction force. Therefore, the hatch can be easily opened.

Here, the magnitude of the elastic reaction force of the torsion spring 170 is set to be such that the hatch cover 110 can be instantly opened to 10° to 45° when opened, and does not hinder the downward movement of the hatch cover 110 by its own weight when closed. Rotate the action.

Further, as shown in Fig. 4, the lower outer peripheral surface of the lock bar 160 is further provided with a compression spring 161 to provide an elastic reaction force for downward movement, and the lower end of the lock bar 160 forms a sliding surface which is inclined from the rear side to the front side to The hatch 110 is inserted into the locking groove 122 when it is rotated downward.

Specifically, the compression spring 161 generates an elastic reaction force that constantly moves the lock bar 160 downward between the spring fixing bar 162 provided on the outer circumferential surface of the locking bar 160 and the locking bar support bar 111 provided on the hatch 110. In addition, since the lower end portion of the locking bar 160 has an inclined shape, when the hatch 110 is rotated downward by its own weight, the sliding of the locking bar 160 The face is in contact with the outer side of the hatch frame 120 such that the locking bar 160 is naturally lifted upwardly, and thereafter, due to the elastic reaction force of the compression spring 161, the locking bar 160 is moved back to the lower portion to automatically engage with the locking groove 122.

Further, the hatch cover device for a ship according to an embodiment of the present invention extends forward at the upper end portion of the lock bar 160 to form a handle bar 163 which functions as a first handle for unlocking the lock bar 160, and is formed in front of the hatch 110. To the state in which the second cover of the hatch 110 is rotated forward by the torsion spring 170 in the state where the hatch 110 is partially opened, the upper end of the side guide bar 150 is further formed to rotate upwardly. The guide strip 150 is a detachment protrusion 153 that functions as a third handle that disengages the opening protrusion 140 from the support step 152.

That is, as can be seen from the operational characteristics to be described, since a semi-automatic operation system that requires external manpower in the operation of opening and closing the hatch 110 is formed, if it is located at a high position that is not accessible to a human hand, a lever can be provided. The strip (not shown) is sufficient to complete the opening and closing operations by three lifting actions. In order to perform the action of jacking up more smoothly, the above structure is further included in an embodiment of the present invention. At the same time, when the hatch is placed at a low position, it is easy to complete the opening and closing operation by holding the handles by hand.

5 to 9 are schematic views for explaining the opening and closing operation of the hatch cover device for a ship according to an embodiment of the present invention, and are side views.

Next, as shown in Fig. 6, after the locking bar 160 is unlocked, a portion of the hatch 110 is instantaneously opened by 10 to 45 due to the elastic reaction force of the torsion spring 170. Due to the pre-opening action using the elastic reaction, the open action can be completed until it is completely open.

Next, as shown in Figure 7, to fully open the hatch cover 110, use a bar or grip When the rotating ring 180 is rotated forward, the side guide bar 150 interlocks with the rotation from the bottom to the front of the opening protrusion 140 to rotate the upper end from the upper side to the front side and guide the opening operation of the hatch cover 110 on the side. In the process in which the open projection 140 is slidably moved by the guide hole 151, when the hatch 110 is completely opened, the open state of the hatch 110 can be fixed by the support protrusion of the guide hole 151 by the open protrusion 140.

Next, as shown in FIG. 8, the side guide bar 150 is rotated upward by the disengagement protrusion 153, and the opening protrusion 140 is detached from the support step.

Next, as shown in FIG. 9, after the detachment operation is completed, the lock bar 160 is automatically coupled and locked to the lock groove 122 due to the self-weight of the hatch 110 being accelerated from the front to the rear, so that the hatch 110 closes the hatch frame 120. At this time, when the hatch 110 is rotated downward, the side guide bar 150 interlocks with the rotation from the front to the bottom of the opening protrusion 140 to rotate the upper end from the front direction and to guide the closing operation of the hatch 110 on the side.

As described above, the hatch cover device for a ship according to an embodiment of the present invention can easily open and close the hatch cover provided on the high wall surface with a small force.

Further, the hatch cover device for a ship according to an embodiment of the present invention can prevent a safety accident from occurring when the hatch cover is opened and closed.
