[0040] A hook assembly is provided on both the front and rear sides of the lifeboat body 17, and the hook assembly includes a mounting plate 1, and two hanger plates 2 are arranged side by side on the top of the mounting plate 1, and a cavity is formed between the two hanger plates 2; a movable hook 3 is rotatably connected to the top of the two hanger plates 2, a stopper frame 4 is arranged on the front side of the two hanger plates 2, and a brake block 5 is rotatably connected to the rear side of the two hanger plates 2, and a brake groove 6 is provided on the top of the brake block 5. When the lower end of the movable hook 3 is stuck in the brake groove 6, the upper end of the movable hook 3 abuts against the stopper frame 4; the bottom of the two hanger plates 2 rotates A half shaft 7 is connected. When the outer ring arc surface of the half shaft 7 conflicts with the brake block 5, the lower end of the movable hook 3 is inserted into the brake groove 6. When the outer ring plane of the half shaft 7 conflicts with the brake block 5, the lower end of the movable hook 3 rotates out of the brake groove 6. A mounting hole 8 is provided through the mounting plate 1. The mounting hole 8 is located on the outside of the cavity. A driving mechanism 9 is provided in the mounting hole 8. The driving mechanism 9 is connected to the half shaft 7 to drive the half shaft 7 to rotate. A shield 10 is provided between the mounting plate 1 and the hanger plate 2. The shield 10 surrounds the mounting hole 8 and covers the driving mechanism 9.

[0041] The driving mechanism 9 includes a hydraulic cylinder 91 and an extension plate 92. The cylinder body of the hydraulic cylinder 91 is arranged in the mounting hole 8. The piston rod of the hydraulic cylinder 91 extends upward from the mounting hole 8.

[0046] The rubber sleeve 27 is sleeved on the outside of the safety pin 16 and contacts the hanger plate 2 and the movable stopper 26. It can not only be used to limit the movable stopper 26 to ensure that the movable stopper 26 can always remain perpendicular to the safety pin 16, but also can be used to limit the safety pin 16 so that the limit pin cannot move axially, thereby avoiding the safety pin 16 from detaching from the two hanger plates 2.

[0047] A torsion spring 28 is provided between the safety pin 16 and the movable stopper 26 . When the torsion spring 28 is in a force-balanced state, the movable stopper 26 is perpendicular to the safety pin 16 .

[0048] When the movable stopper 26 is controlled to pass through the two hanger plates 2 along with the safety pin 16, the movable stopper 26 can be rotated to be perpendicular to the safety pin 16 under the action of the torsion spring 28, which makes the operation more convenient. Furthermore, the torsion spring 28 can keep the movable stopper 26 perpendicular to the safety pin 16 through elastic force, so that the safety pin 16 is not easily separated from the two hanger plates 2.

[0049] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
