Cargo lifting device for ship and installation method

Abstract

The invention discloses a cargo lifting device for a ship and an installation method. The cargo lifting device for the ship comprises a magnetic attraction track, a supporting frame, a winch, a cableand a cargo box; a plurality of temporary cabin entering openings are formed in a hull outer plate in the height direction, and the magnetic attraction track is adsorbed on the hull outer plate; the supporting frame comprises a first part fixed on a hull and a second part extending out of the hull outer plate, the winch is arranged on the first part, and the second part is provided with a pulley;and one end of the cable is connected with the winch, the cable bypasses the pulley, the other end of the cable is connected with a cargo loading box, and the side, close to the hull outer plate, of the cargo loading box is connected with the magnetic attraction track and can be selectively aligned with the plurality of temporary cabin entering openings. According to the cargo lifting device for the ship, the magnetic attraction track is adopted to be directly adsorbed and fixed on the hull outer plate, so that the cargo lifting device is not influenced by the swing drift of a ship, and the occupation of a wharf space is reduced; and the cargo loading box can be stably moved up and down, transportation is safe and the efficiency is high, so that the construction speed of the ship is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a ship cargo lifting device and an installation method. Background technique [0002] Ships such as ro-ro passenger ships and cruise ships have more living quarters. During the construction process, it is necessary to use cranes or manpower to transport a large amount of building materials and decoration materials to the ship for installation and construction work. Such building materials and decoration materials are large in quantity, various in variety and light in weight. When hoisting with a crane, they need to be bound or fixed in other ways before hoisting, which may easily cause deformation or damage to the cargo during hoisting. The area is small, the working space of the crane is small, and the overall lifting efficiency is low. The mode of manual handling is more inefficient and has greater potential safety hazards. If a fixed cargo lifting device is built on th...

AI Technical Summary

Problems solved by technology

Such building materials and decoration materials are large in quantity, various in variety and light in weight. When hoisting with a crane, they need to be bound or fixed in other ways before hoisting, which may easily cause deformation or damage to the cargo during hoisting. The area is small, the working space of the crane is small, and the overall lifting efficiency is low

Manual handling is even more inefficient and poses a greater safety hazard

If a fixed cargo lifting device is built on the wharf, it will take up more dock space, and because the ship will sway and drift with the wind, waves or tides, the practicability of this type of cargo lifting device is poor
