The hatch cover 24 is connected to the hinge 22 and is used to cover the opening 111. The driving member 23 drives the hinge 22 to rotate around the rotating shaft 21 to open and close the hatch cover 24. When the device a needs to be used, the driving member 23 drives the hinge 22 to rotate around the rotating shaft 21, and the hatch cover 24 is opened, so that the device a can be lifted out of the opening 111 to the outside of the first deck 11 for use. Conversely, when the driving member 23 drives the hinge 22 to rotate in the opposite direction around the rotating shaft 21, the hatch cover 24 is closed.

[0041] In some embodiments, in order to avoid the phenomenon of the hatch cover 24 being popped up after being closed, the side of the hatch cover 24 facing the sealed cabin 13 is provided with a first plug-in part 241.

The first oil cylinder 32 drives the first latch 321 to move along the first direction X to approach or move away from the first plug-in part 241. When the device a needs to be used, the first oil cylinder 32 drives the first latch 321 to retract along the first direction X, so that the first latch 321 is disengaged from the first plug-in part 241, and the hatch cover 24 is unlocked. Conversely, when the hatch cover 24 is closed, the first oil cylinder 32 drives the first latch 321 to extend along the first direction X, so that the first latch 321 is plugged with the first plug-in part 241, thereby locking the hatch cover 24, avoiding the hatch cover 24 being accidentally popped up to affect the normal use of the first deck 11 or reduce the stealth performance of the ship.

[0044] The working process of the present application is as follows: Please refer to Figures 1-6 The equipment a is installed on the lifting platform 50.

The winch 421 is started to tighten and wind the cable 424, so that the cable 424 pulls the linear bearing 52 upward along the third direction Z through the cable connecting block 53, thereby lifting the platform body 51. When the platform body 51 is lifted to the position along the third direction Z, the equipment a on the platform body 51 is exposed outside the first deck 11 through the opening 111. At this time, the second oil cylinder 62 drives the second bolt 621 to extend in the first direction X, so that the second bolt 621 is plugged with the second plug-in piece 55, thereby locking the platform body 51. After use, the second oil cylinder 62 drives the second bolt 621 to retract in the first direction X, so that the second bolt 621 is disengaged from the second plug-in piece 55, thereby unlocking the platform body 51. At this time, under the action of the winch 421, the platform body 51 descends along the third direction Z until the equipment a completely enters the closed cabin 13. The driving member 23 drives the hinge member 22 to rotate around the rotating shaft 21, and the hatch 24 is closed. The first oil cylinder 32 drives the first bolt 321 to extend in the first direction X, so that the first bolt 321 is plugged with the first plug-in piece 241, thereby locking the hatch 24.

[0045] To sum up, the shipborne equipment lifting device provided by the application can drive the lifting platform 50 to lift along the third direction Z through the lifting mechanism 40, so that the lifting platform 50 can lift the equipment a, until the whole equipment a is moved to the outside of the first deck 11 through the opening 111, and then the lifting platform 50 is locked along the first direction X through the second locking mechanism 60; after use, the second locking mechanism 60 is unlocked, and the lifting platform 50 together with the equipment a is lowered along the third direction Z under the drive of the lifting mechanism 40, so that the whole equipment a enters the sealed cabin 13, the opening cover opening 111 is closed by the opening and closing mechanism 20, and the opening and closing mechanism 20 is locked along the first direction X through the first locking mechanism 30; the application can hide in the sealed cabin 13 when the equipment a is not used, which can reduce the reflection area of the ship and improve the stealth effect on the one hand, and can avoid occupying the deck space and improve the space utilization rate of the first deck 11 on the other hand.
