Technical Field

[0001] The utility model relates to the technical field of fairleads, in particular to a fairlead device with a replaceable fairlead for large ships. Background Technique

[0002] A fairlead, also known as a "bulwark fairlead", is a closed fairlead device installed on the bulwark to limit the position where the cable is led out, and is a circular or oval-shaped ring casting. Fairleads are usually made of cast iron or cast steel, installed on the bulwark, guiding the cable through the hull, and can prevent the cable from damaging the hull. They are widely used in the mooring of ships and offshore engineering, and are essential devices for ships and offshore engineering.

[0003] In the related art, the fairlead is usually fixedly connected with a fairlead base in a matching manner. The fairlead base has a stabilizing effect. The fairlead is fixedly connected to the hull through the fairlead base, and the cable passes through the fairlead to achieve the fairlead function.

[0004] Generally, it is not convenient to disassemble the fairlead and the fairlead base. When the fairlead is damaged or needs to be repaired, it is inconvenient to disassemble, and even the fairlead base needs to be replaced, which is time-consuming and laborious, and has poor economy. This situation is more serious especially for the fairleads installed on large ships.

[0005] Therefore, the present application provides a fairlead device with a replaceable fairlead for large ships, which improves the replacement efficiency of the fairlead and reduces the operation cost of large ships. Content of the Utility Model
