Description

Technical Field

[0001] The utility model relates to the technical field of ships, and particularly relates to a plug-in modular fairlead sheath. Background Art

[0002] A fairlead is a closed-hole fairlead device used in ships and ocean engineering to define the position where the cable is led out. It is usually a circular or oval ring-shaped casting, which is used to guide the cable through the hull and prevent the cable from damaging the hull, playing a key role in ship mooring and ocean engineering. However, the long-term use of the cable in the fairlead will cause wear, which may lead to cable breakage and cause safety accidents. To prevent this, a fairlead sheath is usually installed inside the fairlead to reduce cable wear and avoid the risk of cable breakage.

[0003] Although the existing fairlead sheaths can protect the cable to a certain extent, there are still some problems. At present, the installation gap between the fairlead sheath and the fairlead is relatively large, which will cause frictional displacement during use and affect the fixing of the sheath. Chinese Patent CN202311580747.4 discloses a fairlead anti-wear gasket and a ship fairlead, including a first protective sleeve and a second protective sleeve which are separately arranged, and a through hole sequentially penetrates through the first protective sleeve and the second protective sleeve; one end of the first protective sleeve is convexly provided with a plurality of insertion blocks, one end of the second protective sleeve is concavely provided with a plurality of slots, and the plurality of insertion blocks and the plurality of slots are in one-to-one corresponding plug-in fit along the central line direction of the through hole; the fairlead anti-wear gasket further includes a plurality of wedge blocks, and the plurality of wedge blocks are respectively embedded in the plurality of slots, and the wedge blocks squeeze the insertion blocks so that the side walls of the insertion blocks are tightly abutted against the side walls of the slots, and the connection stability of the two protective sleeves is ensured by the friction force between the side walls of the insertion blocks and the slots. Although the wall thickness requirements for the first protective sleeve and the second protective sleeve are effectively reduced, the fitting degree of the first protective sleeve and the second protective sleeve to the fairlead cannot be guaranteed, and displacement deformation is likely to occur during long-term practical use, resulting in a gap between the fairlead sleeve and the fairlead, with low use safety and poor stability.
