Ultrahigh-pressure integrated-network woven and twisted anti-burst multipurpose airbag

Abstract

The invention relates to an airbag, in particular to an ultrahigh-pressure integrated-network woven and twisted anti-burst multipurpose airbag. The ultrahigh-pressure integrated-network woven and twisted anti-burst multipurpose airbag comprises a bag body and a connecting bag head and is characterized in that the bag body is formed by compounding a plurality of rubber sheet layers; each rubber sheet layer is formed by weaving and twisting two rubber sheets in a crossed manner; cords are embedded in the rubber sheets; the cords are formed by weaving longitudinal cords and transverse cords in a staggered manner; and angles of the longitudinal cords and the transverse cords of the cords of the two adjacent rubber sheet layers are different from each other. As the angles of the longitudinal cords and the transverse cords of the cords of each rubber sheet layer are different, the cords of the different rubber sheet layers form a * shape so that the anti-burst strength of the airbag is enhanced; therefore, the service life of the ultrahigh-pressure integrated-network woven and twisted anti-burst multipurpose airbag is prolonged and the use cost is reduced for enterprises.

Description

technical field [0001] The invention relates to an airbag, in particular to an ultra-high-voltage integral network woven, wound, and burst explosion-proof multipurpose airbag. Background technique [0002] As we all know, two methods of rail sliding and air bag rolling are generally used when ships on the Yangtze River and inland rivers go up and down the water. The rail slides up and down the water, and the rails are coated with butter, which not only pollutes the environment, but also has high cost, and each rail can only get on and off one ship, causing a lot of waste to the site. Marine airbags, which are easy to use, high quality and low price, small investment, long service life and other characteristics, are widely used by small and medium shipyards all over the world. The currently used marine airbag manufacturing process mainly consists of the following two methods: one is to use multi-layer rubber with cords to cross-laminate vertically and horizontally, and roll ...

AI Technical Summary

Problems solved by technology

The track slides up and down the water, and the track is coated with butter, which not only pollutes the environment, but also has a high cost, and each track can only get on and off one ship, which causes a lot of waste to the use of the site. my country pioneered the use of air bags to launch and launch the ship, that is, Marine airbag, which is easy to use, high quality and low price, small investment, long service life, etc., is widely used by small and medium-sized shipyards all over the world

The current manufacturing process of marine airbags mainly consists of the following two methods: one is to use multi-layer rubber with cords for vertical and horizontal lamination, and roll them into a cylindrical shape, which is called lap airbags. Its disadvantages are many The layers of rubber with cords are laminated across the warp and weft, and the cord rubber is in the shape of a parallelogram. Therefore, the products of this process have low strength during use. The structure of the cords is not stable, and it is easy to burst in a large area and cannot be repaired. The other is fixed on the type tire frame, and the rubber cord with the cord is wound into a cylindrical shape, which is called a wound airbag. Close rolling, the airbag is prone to detachment between the cord layers during use, resulting in gas leakage, which is also irreparable
