In this way, the balance and stability of the lifting platform 50 moving along the third direction Z can be ensured by arranging the two groups of guide assemblies 41, so as to ensure the normal use of the equipment a.

[0071] In some embodiments, as Figure 4As shown, the guide assembly 41 comprises a linear guide rail 411, a first base 412 and a second base 413, wherein the linear guide rail 411 extends along the third direction Z, the lifting platform 50 is slidingly installed on the linear guide rail 411, the first base 412 is arranged on the side of the linear guide rail 411 close to the first deck 11 along the third direction Z, and the first base 412 is connected with the first deck 11, and the second base 413 is arranged on the side of the linear guide rail 411 close to the second deck 12 along the third direction Z, and the second base 413 is connected with the second deck 12. In this way, the guide assembly 41 can not only guide the lifting platform 50, but also provide a downward supporting force for the first deck 11, thereby ensuring the supporting strength of the first deck 11.

[0072] In some embodiments, the lifting mechanism 40 further comprises a winch assembly 42, which is arranged in the closed cabin 13 and connected with the lifting platform 50. The winch assembly 42 is configured to drive the lifting platform 50 to move along the third direction Z, so as to lift or lower the lifting platform 50 along the third direction Z.

[0073] In some embodiments, the winch assembly 42 comprises a winch machine 421, at least one first guide pulley assembly 422, at least one second guide pulley assembly 423 and a cable 424, wherein the winch machine 421 is arranged on the second deck 12; the at least one first guide pulley assembly 422 is arranged on the second deck 12; the at least one second guide pulley assembly 423 is arranged on the side of the first deck 11 facing the second deck 12; one end of the cable 424 is connected with the output end of the winch machine 421, and the other end is sequentially wound around the first guide pulley assembly 422 and the second guide pulley assembly 423 and connected with the lifting platform 50. In this way, by arranging the first guide pulley assembly 422 and the second guide pulley assembly 423, the direction of the force can be changed, the lifting flexibility of the lifting platform 50 in the limited space of the closed cabin 13 can be improved, and the friction loss of the cable 424 can be reduced, thereby prolonging the service life.

[0074] In some embodiments, the lifting platform 50 comprises a platform body 51, a linear bearing 52 and a cable connecting block 53. The linear bearing 52 is connected with the platform body 51, and the linear bearing 52 is slidingly connected with the linear guide rail 411 along the third direction Z.

[0079] In some embodiments, the opening and closing mechanism 20 comprises a rotating shaft 21, a hinged piece 22, a driving piece 23 and a hatch cover 24. The rotating shaft 21 is arranged at the opening 111 of the first deck 11 along the first direction X. The hinged piece 22 is connected with the rotating shaft 21. The driving piece 23 is arranged on the side of the first deck 11 facing the second deck 12, and the output end of the driving piece 23 is connected with the hinged piece 22.

The driving piece 23 is used to drive the hinged piece 22 to rotate around the rotating shaft 21 to open and close the hatch cover 24. When the equipment a needs to be used, the driving piece 23 drives the hinged piece 22 to rotate around the rotating shaft 21, and the hatch cover 24 is opened, so that the equipment a can be lifted from the opening 111 to the outside of the first deck 11 for use. Conversely, when the driving piece 23 drives the hinged piece 22 to rotate reversely around the rotating shaft 21, the hatch cover 24 is closed.

[0080] 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 closed cabin 13 is provided with a first plug-in piece 241. The first locking mechanism 30 comprises a first connecting piece 31 and a first oil cylinder 32.

The first oil cylinder 32 is connected with the first connecting piece 31, and the output end of the first oil cylinder 32 is provided with a first bolt 321. The first oil cylinder 32 is used to drive the first bolt 321 to move along the first direction X to approach or move away from the first plug-in piece 241. When the equipment a needs to be used, the first oil cylinder 32 drives the first bolt 321 to retract along the first direction X, so that the first bolt 321 is separated from the first plug-in piece 241, and the hatch cover 24 is unlocked. Conversely, when the hatch cover 24 is closed, the first oil cylinder 32 drives the first bolt 321 to extend along the first direction X, so that the first bolt 321 is plugged with the first plug-in piece 241, thereby locking the hatch cover 24, and avoiding the hatch cover 24 being popped up accidentally to affect the normal use of the first deck 11 or reduce the stealth performance of the ship.

[0081] In some embodiments, in order to make the opening and closing of the hatch cover 24 more stable and smooth, the side of the hatch cover 24 facing the closed cabin 13 is provided with a first counterweight 242, and the first deck 11 is provided with a second counterweight 112 near the opening 111. The first counterweight 242 and the second counterweight 112 are connected with an elastic piece 25. The arrangement of the elastic piece 25 makes the hatch cover 24 always in a tension state. Under the action of the driving piece 23 and the hinged piece 22, the opening and closing of the hatch cover 24 is more stable and smooth.

[0082] In some embodiments, the shipborne equipment lifting device further comprises a controller, which is arranged in the sealed cabin 13, and the opening and closing mechanism 20, the first locking mechanism 30, the lifting mechanism 40 and the second locking mechanism 60 are all controlled by the controller to realize automatic control through the controller.

[0086] 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 part 55, and the locking of the platform body 51 is released, 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 sealed cabin 13, the driving part 23 drives the hinged part 22 to rotate around the rotating shaft 21, and the cabin cover 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 part 241, thereby locking the cabin cover 24.

[0087] 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.
