The climbing embarkation mechanism first fixes the pad 4 to the hull with bolts. Under normal circumstances, only the cross bar 2 and the support rod 3 are installed on the top of the vertical rod 1 for storing items. When it is needed to be used as a life-saving equipment, the mounting frame 5 is fixedly connected to the cross bar 2 by bolts. When the life raft moves to the vicinity of the embarkation ladder, the clamping mechanism 9 is adjusted to be clamped and fixed with the first clamping groove 7, so that the extension mechanism is extended from the inside of the mounting frame 5, allowing the lifeguard to pull and support, and then the lifeguard passes through the cross bar 2 from the support rod 3, and then lands on the hull from the embarkation mechanism. The device can be improved on the basis of the existing device, which reduces the production cost of the shipyard, simplifies the production process, and improves the construction efficiency.

[0026] Among them, the clamping mechanism 9 includes a telescopic rod 91, an adjusting plate 92, a clamping block 93 and a spring 94. The inner side of the telescopic rod 91 is fixed on the connecting rod 10, and the outer side is fixed on the adjusting plate 92. The outer side of the adjusting plate 92 is fixed with a clamping block 93, and the clamping block 93 is clamped and fixed with the first clamping groove 7 and the second clamping groove 8. The outer side of the telescopic rod 91 is sleeved with a spring 94, and the spring 94 is located between the adjusting plate 92 and the connecting rod 10. The staff squeezes the adjusting plate 92 inward to make the telescopic rod 91 contract, and then pulls the clamping block 93 out of the second clamping groove 8, and then pushes the connecting rod 10 to the side close to the first clamping groove 7, and then releases the adjusting plate 92, so that the spring 94 drives the telescopic rod 91 to perform a reset movement, and the clamping block 93 is clamped and fixed in the first clamping groove 7.

[0027] Among them, the extension mechanism includes a mounting plate 11, a moving rod 12 and a limit plate 13. The mounting plate 11 is fixed on the connecting rod 10, and the moving rod 12 is fixed on the mounting plate 11. The moving rod 12 slides through the mounting frame 5 and is fixed on the limit plate 13 on the outer side. When the connecting rod 10 moves to the side close to the first clamping groove 7, the mounting plate 11 drives the moving rod 12 to move outward, thereby making the limit plate 13 move to the side away from the mounting frame 5, so that the lifeguard can pull the limit plate 13 on the shaking lifeboat and then climb onto the hull.

[0028] There are two movable rods 12 symmetrically disposed on both sides of the connecting rod 10 , which can improve the stability of the movement of the limiting plate 13 .

[0029] Among them, the boarding mechanism includes a connecting plate 14, a mounting side plate 15 and a pedal 16. The connecting plate 14 is fixed to the outer side of the vertical rod 1. The middle part of the connecting plate 14 is fixedly connected to the mounting side plate 15 by bolts. The inner side of the mounting side plate 15 is fixedly connected to the pedal 16 by bolts. The lifeguard climbs onto the hull from the cross bar 2 through the pedal 16.

[0030] There are two mounting frames 5 symmetrically arranged at the front and rear sides of the crossbar 2 , which are convenient for lifeguards to support and walk on the support rod 3 .

[0031] Wherein, rubber pads are fixedly installed inside the first clamping groove 7 and the second clamping groove 8 , which can improve the stability of the connection between the clamping block 93 and the support tube 6 .

[0032] Among them, four vertical rods 1 are arranged, symmetrically distributed at the four corners of the lower end of the cross rod 2. The vertical rods 1 are made of Q234-A steel, which can improve the installation stability of the cross rod 2 and the support rod 3.

[0033] The mounting frame 5 is made of Q235B steel, which is corrosion-resistant and has high hardness, thereby increasing the overall service life.

[0034] Among them, eyelets 17 are fixed on both sides of the cross bar 2 to facilitate the installation of binding ropes and to store and fix the ladder stored on the upper end of the support rod 3.

[0035] Working principle: When in use, firstly, the pad 4 is fixedly connected to the hull by bolts. Under normal circumstances, only the cross bar 2 and the support rod 3 are installed on the top of the vertical rod 1 for storing items. When it is needed to be used as a lifesaving device, the mounting frame 5 is fixedly connected to the cross bar 2 by bolts. When the life raft moves to the vicinity of the embarkation ladder, the staff presses the adjustment plate 92 inward to shrink the telescopic rod 91, and then pulls the clamping block 93 out of the second clamping groove 8, and then pushes the connecting rod 10 to the side close to the first clamping groove 7, and then loosens the adjustment plate 92 to make the elastic The spring 94 drives the telescopic rod 91 to perform a reset movement, and the clamping block 93 is clamped and fixed in the first clamping groove 7. When the connecting rod 10 moves to the side close to the first clamping groove 7, the mounting plate 11 drives the moving rod 12 to move outward, thereby causing the limit plate 13 to move to the side away from the mounting frame 5, so that the lifeguard can hold the limit plate 13, climb onto the support rod 3, and then climb from the cross bar 2 to the hull through the pedal 16. The device can be improved on the basis of the existing device, reducing the production cost of the shipyard, simplifying the production process, and improving the construction efficiency.
