Rubber guard, also known as rubber guard, is installed on a dock or the ship to absorb the collision energy between the ship and the dock or the ship at the landing or mooring, and plays the function of protecting the safety of the ship and the dock. Due to the advantages of high energy absorption, low reaction force, aging resistance, long service life and easy installation, with the continuous development of modern shipbuilding industry, rubber guard has gradually become a very popular terminal safety protection device. Due to the different requirements for guard cover, the characteristics of rubber provides diversified options for various ships and berthing environment. According to the different structure, the rubber guard can be divided into solid rubber guard and floating rubber guard two different types. Solid rubber guard is also known as non-floating guard, which has a history of application very early, and it is also the safety protection device of wharf ships with the highest penetration rate. According to the different forces, the rubber guard can be divided into shear, rotation and compression, etc. Compared with other types of ship terminal safety protection devices, this solid guard has the advantages of good energy absorption, low cost and long service life.
Drum rubber guard performance characteristics
1. In the case of no increase in the reverse force, the deformation distance increases by 13%, the energy absorption increases by 17%, and the energy absorption ratio per unit reverse force (E / RH) increases by 15%
2. In the compression guard series, the unit weight of the drum guard has the highest energy absorption
Model | Specifications | Product weight (rubber)(TON) | To absorb energy(KN·M) | Tons of rubber energy absorption ratio(％) | Remark |
The cylinder type | 1000φ×500φ×1000L | 0.711 | 65.7 | 100 | |
Semi-circular | 500H×2000L | 0.440 | 62.8 | 154 | |
Arch form | 500H×1000L | 0.220 | 72.0 | 355 | |
Drum type | 800H | 0.230 | 98.0 | 453 |
3, port front with steel frame, thus greatly reduce the effect on the ship board surface pressure, according to the need of surface pressure up to 25 tons / m 2 below, especially suitable for large ships berthing
4, due to the unit reverse force suction energy is high, especially suitable for the needs of the sea wharf, especially the pier wharf
5, in compressed rubber port series, drum port tilt compression performance change small
6, steel frame installation PE panel, reduce the friction coefficient, make the berthing shear force is greatly reduced.
