A roller fairlead with cable maintenance function

Abstract

The invention discloses a roller fair lead with a mooring rope maintenance function, and belongs to the field of ship engineering. The roller fair lead with the mooring rope maintenance function comprises a fair lead body, rollers are rotatably connected with the inner end of the fair lead body, and arc-shaped ring grooves are formed in the outer ends of the rollers. A plurality of spherical grooves uniformly distributed are formed in the side wall of each arc-shaped ring groove, flow guiding rolling balls are rotatably connected to the inner ends of the spherical grooves, and cylindrical fineprotrusions are fixedly connected to the upper and lower ends of the flow guiding rolling balls. Frictional force between the fair lead and a mooring rope can be reduced, so that the service lives ofthe mooring rope and the fair lead are prolonged, when the mooring rope acts on the fair lead, lubricating oil can be led to the exterior of the fair lead through a rate-limiting flow guiding mechanism, so that the mooring rope is coated with the lubricating oil to realize lubricating maintenance of the mooring rope; and when the mooring rope does not act on the fair lead, the lubricating oil canbe stopped from being led to the outer side of the fair lead through a self-sealing mechanism, so that waste of the lubricating oil is reduced, and the resource utilization rate is improved.

Description

technical field [0001] The invention relates to the field of ship engineering, in particular to a roller fairlead with the function of cable maintenance. Background technique [0002] Fairleads, also known as "cable pliers" and "cable hooks", refer to cable-bearing appliances used to guide cables through or change directions to protect cables from wear. It is generally a metal crab claw, and some have a round pile or a roller between the two claws and set it on the deck or wharf of the ship. It is used to lead the cable out from a certain point beside the ship or the dock. The roller fairlead is a kind of fairlead. The rollers of the commonly used roller fairleads are mostly fixed structures. In some applications, the protruding rollers will affect the engineering operations and bring certain troubles to the engineering operations. . [0003] However, the flexibility of the fairlead needs to be strengthened, and the protection against it during the movement of the fairlea...

Problems solved by technology

The roller fairlead is a kind of fairlead. The rollers of the commonly used roller fairleads are mostly fixed structures. In some applications, the protruding rollers will affect the engineering operations and bring certain troubles to the engineering operations.

[0003] However, the flexibility of the fairlead needs to be strengthened, and the protection against it during the movement of the fairlead is not enough, which causes serious abrasion between the surface of the cable and the fairlead, seriously affecting the service life of the cable and the fairlead
