Anti-corrosion mooring fixing chain

Abstract

The invention discloses an anti-corrosion mooring fixing chain. An annular cushion block is arranged on a shackle and is in sleeving connection with an embedded ring on a wharf breast wall; when the fixing chain is impacted by external force, the annular cushion block rotates on a screw rod of a bolt to reduce friction force, and therefore the abrasion risk at a connecting position is lowered; a damping device is arranged, when the fixing chain is impacted by external force, and is extruded or stretched, an internal rubber block damps vibration, and the breakage risk of the fixing chain is further lowered. Moreover, through selection of appropriate materials, surface oxidation resistance is achieved, and the anti-corrosion mooring fixing chain is resistant to corrosion and salt and is applicable to various waters. Through the anti-corrosion mooring fixing chain, the problem that fixing chains and sleeving connection positions are prone to breakage due to long-time stress and corrosionin the prior art can be effectively solved, and the instability of ships reaching a port during large stormy waves is greatly lowered.

Description

technical field [0001] The invention relates to a fixing device, in particular to a corrosion-resistant mooring fixing chain. Background technique [0002] In the prior art, ships need to be buffered when berthing to avoid direct collision with the parapet of the wharf. Generally, an anti-scour assembly composed of wooden frames, rubber or steel components is used. When these devices are installed, the shackles on the ring chain and the parapet of the wharf are usually required to be installed. Fixed on the pre-embedded ring above. However, the joints of the existing shackles and embedded rings are easy to wear and become thinner under long-term stress due to tides, and the ring chains are also subject to stress wear, and seawater is more likely to corrode ordinary carbon steel metal parts, plus Anti-corrosion maintenance is not easy. In some areas or seasons with strong wind and waves, the greater force on the buffer equipment during berthing will cause the above-mentioned...
