The invention relates to the technical field of ships, in particular to a fairlead anti-abrasion gasket and a ship fairlead, the fairlead anti-abrasion gasket is provided with a through hole for a fairlead to penetrate through, the fairlead anti-abrasion gasket comprises a first protective sleeve and a second protective sleeve which are arranged in a split mode, and the through hole sequentially penetrates through the first protective sleeve and the second protective sleeve; a plurality of insertion blocks are convexly arranged at one end of the first protective sleeve, a plurality of insertion grooves are concavely formed in one end of the second protective sleeve, and the insertion blocks and the insertion grooves are in one-to-one corresponding insertion fit in the center line direction of the through hole; the fairlead anti-abrasion gasket further comprises a plurality of wedge blocks, the wedge blocks are embedded into the inserting grooves in a one-to-one correspondence mode, the wedge blocks extrude the inserting blocks so that the side walls of the inserting blocks can abut against the side walls of the inserting grooves, it is guaranteed that the two protection sleeves are stably connected through friction force between the inserting blocks and the groove walls of the inserting grooves, the integrity of the inner wall of the through hole is guaranteed, and therefore the cable is prevented from being abraded. And screw holes do not need to be formed, the requirement for the wall thickness of the two protective sleeves can be lowered, and then the wall thickness can be reduced.
本发明涉及船舶技术领域,具体公开了一种导缆孔防磨衬垫及船舶用导缆孔,导缆孔防磨衬垫具有用于导缆穿过的通孔,导缆孔防磨衬垫包括分体设置的第一保护套和第二保护套,通孔依次贯穿第一保护套和第二保护套;第一保护套的一端凸设有若干插块,第二保护套的一端凹设有若干插槽,若干插块和若干插槽沿通孔的中心线方向一一对应地插接配合;导缆孔防磨衬垫还包括若干楔块,若干楔块一一对应地嵌于若干插槽,且楔块通过挤压插块以使插块的侧壁抵紧于插槽的侧壁,借助插块和插槽的槽壁之间的摩擦力保证两个保护套连接稳定,并保证通孔的内壁的完整性,以避免磨损缆绳;并且无需设置螺孔,对于两个保护套的壁厚需求也会降低,进而可减薄壁厚。
