Heavy Lifting Marine Salvage Airbags

 

 

Airbag advantages:
Put a lot of uninflated cylindrical bladders under the bottom of the boat, then inflate the top of the boat, remove other obstacles below, and then slowly release the airbags at the back a little bit, and place the hull a little backward. If you use the power to push it a little bit in the front, the boat will naturally go into the water behind, and the boat will be launched.


Ship launching in the shipbuilding industry is a relatively complex process. Inland and coastal shipping ships generally use track sliding and airbag rolling methods. Track sliding requires a berth or dock. Due to high investment costs and small scope of application, it is generally only used. Selected by large shipyards. Marine airbags are widely used by small and medium-sized shipyards due to their small overall investment and wide range of applications.


Heavy goods handling:


Marine airbags are widely used in caisson lifting, transportation, launching and other fields in port construction, as well as component displacement and launching.

Floating and salvage:


Marine airbags can generate greater buoyancy and strong load-bearing capacity, and are now widely used in rescue of stranded ships and other buoyancy and salvage fields.

The principle of ship airbag hauling:


The working principle of the airbag "roller" hauling caisson is basically the same as that of the drum hauling heavy objects. Several airbags are placed between the bottom of the caisson and the ground, and the caisson is inflated to lift the caisson, and then the caisson is pulled by external force to roll the airbag, thereby driving the caisson to move. Compared with the traditional roller, the airbag can produce greater deformation under the weight of the caisson. Increase the contact area between the airbag and the ground, so that the pressure per unit area is reduced, the force is even, and the adaptability to the site is strong. The structure and characteristics of the structure The airbag is a long cylindrical shape and consists of 3 layers of rubber and nylon cord fabric. The inner and outer layers are rubber layers, and the middle is a nylon cord fabric layer.

Airbag packaging and transportation:


According to the provisions of the CB/T 3795-1996 of the People's Republic of China Ship Industry Standard, the packaging, transportation and storage of marine airbags should comply with the following standards:


1. Packaging
Folded and packed with plastic woven bags.


2. Transportation
Airbags should be lifted, lifted, and rolled in an inflated state when transported on short distances. It is strictly forbidden to drag on the ground.


The airbag should be folded and fixed to the tray during long-distance transportation, with a cushion underneath, and wrapped with a wrapping film on the outside.

The development history of marine airbag:


According to related records, humans have been using the rolling wood principle to carry heavy objects more than 6,000 years ago. People still use the rolling wood principle to carry heavy objects in daily production and life. Marine airbag is a flexible heavy vehicle designed according to the principle of rolling wood.


In the 1980s, due to the manufacturing process and materials of airbags, the weight of airbag launching ships was between 100 tons and 500 tons.


In the early 1990s, people made innovations in the process and materials of airbag manufacturing: nylon cords replaced canvas as a new skeleton material, and a new type of integral winding manufacturing process was developed.


Some marine airbag manufacturers still use the old production technology of lap type. It is generally believed that the integrally produced marine airbag is more reasonable in structure and has a greater safety factor and bearing capacity.


Water-filled blasting test is an important method to check the performance of marine airbags.
