Lifeboat hoisting structure

Abstract

The invention provides a lifeboat hoisting structure. By means of the lifeboat hoisting structure, the situation that when a lifeboat is hoisted and placed, the lifeboat shakes large, and side deflection of the lifeboat is caused is effectively prevented, and safety of staff in the lifeboat can be guaranteed. The lifeboat hoisting structure is characterized in that the lifeboat hoisting structure comprises a door frame type hoisting arm, and a winch is arranged on the hoisting arm; a suspension type cross beam is arranged at the upper end of the hoisting arm, and each of the two ends of the cross beam is provided with a movable roller and a hoisting hook; fixed rollers are arranged in the positions, corresponding to the two ends of the cross beam, of the hoisting arm; one end of the hoisting arm is provided with a middle roller corresponding to the fixed roller at the end; a supporting roller corresponding to the middle roller is arranged on the hoisting arm; the central axis of the fixed rollers longitudinally intersects with the central axis of the middle roller; the central axis of the fixed rollers horizontally intersects with the central axis of the supporting roller; a hoisting rope is sequentially wound across the winch, the supporting roller, the middle roller, the fixed roller at one end and the movable rollers and is finally fixed to the fixed roller at the other end.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery components. Specifically, it is a lifeboat lifting structure. Background technique [0002] When a ship is sailing at sea, when encountering working conditions, people usually use lifeboats to escape. The lifeboats are placed on the ship. Lifeboat escape, due to the heavy weight of the lifeboat and people, when the lifeboat is hoisted and placed, the lifeboat will shake a lot, which will cause the lifeboat to sideways, which will affect the safety of the people in the lifeboat. Contents of the invention [0003] In view of the above problems, the present invention provides a lifting structure for a lifeboat, which effectively prevents the sideways deviation of the lifeboat when the lifeboat is lifted and placed and the lifeboat shakes greatly, thereby ensuring the safety of the people in the lifeboat. [0004] The technical solution is as follows: a lifeboat lifting structure, which...
