Abstract

The invention relates to a chain cable securing device for a ship, which can be widely used for water drum mooring of the ship during defending against a hurricane. The chain cable securing device for the ship comprises a base and a manual opening and closing mechanism which is configured together with the base, wherein the manual opening and closing mechanism comprises a press cover with one end hinged with the base; an internal arc groove and an external arc groove are respectively formed inside and outside the press cover configured together with the base; the press cover is connected with a manual rocking bar by a connecting bar and the other end of the manual rocking bar is hinged with the base so that a double-rocking-bar type manual opening and closing mechanism; the manual rocking bar of the manual opening and closing mechanism is connected with a self-locking mechanism; and the self-locking mechanism is connected with a manual unlocking device. The chain cable securing device for the ship, provided by the invention has the advantages of compact and reasonable structure, high reliability, small appearance, light weight, high bearing load, strong hurricane defending mooring function, convenience in use, functions of rapidly clamping, automatically locking and rapidly unlocking hurricane defending chain cables and capability of being widely used for water drum mooring of the ship during defending against the hurricane.

Description

technical field [0001] The invention relates to a fixed anti-typhoon mooring chain cable device for ships, which can be widely used for mooring with water drums when ships are anti-typhoon. Background technique [0002] The mooring and towing system is an important part of the ship, which is of great significance to the safety of the ship. In the condition of strong wind and waves, in order to avoid the collision between the ship and the wharf, it is necessary to prevent the typhoon through the mooring drum at the anchorage. The existing standard single-point mooring chain catcher for mooring water drums has large dimensions, heavy weight, small working load, small diameter of the clamping anchor chain, and cannot be released quickly, so it is widely used on large and medium-sized ships. restrict. According to CB / T3672-1995, the maximum safe working load of single point mooring equipment on ships is only 200t. Therefore, for the safety of large ships, it is necessary to de...
