AI Technical Summary

Technical Problem

Existing life rafts cannot maintain their centrality continuously, resulting in easy shaking during ship movement.

Method used

A life raft hoisting device is designed, including a main frame, a plurality of positioning members and a lifting ring system. The main frame is provided with a through hole, a beam, a first suspended ring and a plurality of second suspended rings on the top, and a plurality of positioning members are arranged in a horizontal direction for positioning and connection with the fixture of the life raft. By adjusting the position of the rope and positioning members, the movement of the life raft in the height direction and the centrality of the center are achieved.

Benefits of technology

Through this device, the center of the life raft can be effectively maintained, the shaking during the ship's movement can be reduced, and the stability of the life raft can be improved.

Abstract

The present application provides a life raft hoisting device, which includes a main body frame and a plurality of positioning members; a through hole is provided in the main body frame for the life raft to pass through; a cross beam, a first lifting ring and a plurality of second lifting rings are provided at the top of the main body frame, and the plurality of second lifting rings are distributed at the ends of the main body frame; the first lifting ring is connected to the lower side wall of the cross beam and is jointly traction-connected with the plurality of second lifting rings to the ropes of the fixture of the life raft, so that the ropes can be tractioned along the plurality of second lifting rings and the first lifting ring under the action of manual force or driving force, thereby realizing the movement of the life raft in the height direction. The plurality of positioning members are arranged at the positioning stations of the main body frame, the plurality of positioning members are arranged along the horizontal direction and are at the same height; the plurality of positioning members are arranged annularly along the inner side wall of the through hole and are distributed around the fixture connected to the life raft to be positioned and connected with each side surface of the fixture, ensuring the centricity of the fixture of the life raft and the life raft relative to the center of the positioning station.
