Description

Marine push-down boat lifting frame

Technical Field

The utility model relates to a boat davit specifically is a marine push-down boat davit belongs to marine equipment technical field.

Background

The boat davit is a special hoisting device which is carried by a ship and used for hoisting and placing a boat. According to different folding and unfolding modes, the folding and unfolding type can be divided into a gravity type, a swing-out type and a swing-out type.

The davit is of many types, and the current use can be roughly divided into gravity type and inverted lever type (rotary type is not adopted on the sea ship). The gravity type boat davit can be divided into a slide rail type and an inclined type, and the gravity type boat davit can be divided into a plurality of different structural shapes due to different arrangement statuses in the slide rail type and the inclined type. The inverted bar type boat davit can be divided into a straight bar type and a sickle type, and the two types can also be divided into various structural shapes due to different requirements and arrangement.

The gravity type boat lifting frame which is adopted on the sea ship more acts rapidly, is safe and reliable when the boat is placed, and after the braking device is opened, the boat lifting frame releases the boat under the action of gravity without power driving. However, the lifeboat davit of this type has a disadvantage that the lifeboat is usually suspended on the davit, which relatively increases the center of gravity of the ship.

The certain height must be hoisted with the ship to the outboard to the general when putting the ship of down-bar formula boat davit or rotation type boat davit, and speed is slower when consequently putting the ship, and it is also great to occupy the deck area simultaneously. The boat davit is because the boat is directly place on deck, compares with above-mentioned gravity type, can reduce a little relatively to boats and ships focus. The inverted bar type boat davit is used on inland ships.

The existing boat davit is simple in structure, one of the boat davit is not of a push rod type, the power device occupies a large volume, is not beneficial to light weight, consumes energy, is large in quantity and low in efficiency, is poor in modularization, is not easy to disassemble and assemble, brings inconvenience to production and maintenance, and the other one of the boat davit is not beneficial to sustainable development due to the fact that gas is adopted as an energy source, pollutes the environment.
