CCS Ship Launching Rescue Marine Salvage Airbags

Rescue Airbag With Inflatable Airbag With Ship Launching Airbag

Application areas of airbags:

Ship launching and launching:

After more than 20 years of practice, launching ships have developed from flat-bottomed ships weighing tens of tons to large ships with tens of thousands of tons. Practice has proved that the airbag launching process is safe and reliable. This technology has been recognized by the shipbuilding industry and port construction industry at home and abroad, and the airbag launching technology has been promoted in the United States, Europe, Southeast Asia and other countries.

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.

Inflatable Marine Rubber Airbag Technical Parameter

Features of ship airbag:

(1) The airbag is formed by a unique integral winding process, and the airbag wall has no seams. The strength is balanced in all directions, so the burst strength and the number of impact fatigue resistance are increased; (2) Because it uses compressed air as a buffer medium, it has a soft pressure relief effect, absorbs impact energy, and has low stress on the transported object. Excellent impact performance.

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.

Technical requirements for marine airbags:

According to CB/T 3795-1996, marine airbags should meet the technical requirements

1. Size deviation
The deviation of diameter and effective length is -2%---+2%,
The deviation of the total length is -4%---+4%

2. Elastic deformation
When using 1.2 times the working pressure as the experimental pressure, the diameter deformation is not more than 5%

3. Safety factor
Safety factor is not less than 4.5

4. Airtightness
Inflate for 1h, the pressure drop is not more than 5%

5. Appearance requirements
Linear smooth, no cracks and bubbles, heavy skin, mixed impurities and obvious dirt and other visual defects.

6. Safety inflation device
The safety valve should be installed on the capsule, and the trip pressure of the safety valve should be 1.25 times of the working pressure.

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.
