Embodiment 1

[0065] Such as figure 1 As shown, the multi-functional double-layer anti-swing six-degree-of-freedom wave compensation device of the present invention is arranged on the supply ship A, and can lift cargo 12 to the receiving ship B, and the multi-functional double-layer anti-swing six-degree-of-freedom device of the present invention The wave compensation device can cooperate with the helicopter C to realize the supply of the supply ship A by the helicopter, including supplies and personnel, such as Figure 7 shown.

[0066] Such as figure 2 As shown, the multi-functional double-layer anti-sway six-degree-of-freedom wave compensation device includes a cargo crane 1 arranged on a supply ship and a wave compensation mechanism whose upper part is connected to the boom 101 of the cargo crane 1 . The wave compensating mechanism includes an upper platform 2, a middle platform 3 and a lower platform 4 arranged sequentially from top to bottom. Wherein, the upper platform 2 and the ...

Embodiment 2

[0087] Such as Figure 11 As shown, the difference between this embodiment and Embodiment 1 is:

[0088] The middle platform includes the first layer 301 of the middle platform and the second layer 302 of the middle platform arranged in sequence from top to bottom. The first layer 301 of the middle platform and the second layer 302 of the middle platform are parallel to each other and fixedly connected. In this embodiment, the middle platform The first layer 301 of the platform and the second layer 302 of the middle platform are fixedly connected by several supporting connecting columns 303 . The ball bearing outer lining 602 is fixed to the second layer 302 of the middle platform, and the center of the first layer 301 of the middle platform has a central hole with a diameter greater than the outer diameter of the outer rod 501 of the telescopic rigid rod 5 .

[0089] On the upper surface of the first layer 301 of the middle platform, near the edge, the first rotating motor u...

Abstract

The invention relates to the field of marine equipment, and aims to provide a multifunctional double-layer anti-swing six-degree-of-freedom wave compensation device. The device is good in compensation effect and capable of not only compensating side-by-side supply of ships on the sea, but also performing wave compensation on relative movement of a cargo supply ship and an air supply helicopter. A wave compensation mechanism comprises an upper platform (2), a middle platform (3) and a lower platform (4) which are sequentially arranged from top to bottom, the upper platform (2) is connected with the middle platform (3) through twelve retractable upper platform steel wire ropes, the middle platform (3) is connected with the lower platform (4) through twelve retractable lower platform steel wire ropes, the center position of the upper platform (2) is connected with the upper end of a telescopic rigid rod (5), the telescopic rigid rod (5) penetrates through the center position of the middle platform (3), and the lower end of the telescopic rigid rod (5) is connected with the center position of the lower platform (4).

Description

technical field [0001] The invention relates to the field of marine mechanical equipment, in particular to a multifunctional double-layer anti-swing six-degree-of-freedom wave compensation device. Background technique [0002] During the process of the ship being docked for replenishment at sea, the two ships need to berth briefly at sea. Due to factors such as the tonnage, scale, line shape of the supply ship and the receiving ship, and the relative positions of the two ships on the waves, etc., at the same time, Considering the influence of environmental factors such as wind direction and wave direction, there will be relative motion in six degrees of freedom between the two ships, including sway, surge, heave, roll, pitch, and yaw, and this relative motion will be upgraded with the sea conditions Intensified, it is easy to cause the cargo to slip and deviate from the normal landing point. In severe cases, the cargo may even collide with the superstructure on the deck or o...
