Problems solved by technology

First, the structure is large in size, high in material cost, contains reinforcing ribs, increases processing costs, and has poor mechanical properties
Second, the friction between the fairlead and the cable is relatively large, the cable is easily damaged, and the service life is short
Third, the rollers in conventional friction reducing devices have only one rotational degree of freedom, which is poorly applicable to working conditions and cannot be lubricated

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1 to Figure 7 As shown, the present invention discloses a fairlead, which includes an inner shell 2 and an outer shell 1 for accommodating the inner shell 2 . The outer shell 1 is provided with a front wall 14 , a rear wall 15 and two side walls 16 , as well as an opening 17 passing through the front wall 14 and the rear wall 15 . The two side walls 16 have an inner surface 162 and an outer surface 161, the shapes of the inner surface 162 a...

Abstract

The invention discloses a mooring pipe. The shapes of an inner-layer shell and an outer-layer shell of the mooring pipe are manufactured through simulating the outline curve of a goose egg, steel balls serving as rollers in a friction reducing device are embedded between the inner-layer shell and the outer-layer shell, and the steel ball rollers are lubricated. The mooring pipe of the structure has the advantages of being smaller in size, free from reinforcing ribs, good in mechanical property and the like, and the mooring pipe is internally provided with a mechanism used for reducing the friction between the mooring pipe and a mooring rope, and the mechanism can be lubricated.

Description

technical field [0001] The invention relates to the field of ships and marine engineering equipment, and mainly relates to the field of a fairlead. Background technique [0002] The fairlead is also called "bulwark cable hole". It is a closed hole-shaped fairlead embedded in the bulwark or fixed on the deck, which is used to limit the export position of the cable. It is a round or oval ring casting. Widely used in the mooring of ships and ocean engineering, it is an essential equipment for ships and ocean engineering. [0003] Traditional fairleads have the following problems. First, the structure is large in size, high in material cost, contains reinforcing ribs, increases processing costs, and has poor mechanical properties. The second, the frictional force between fairlead and cable is bigger, and cable is easily damaged, and service life is shorter. Thirdly, the rollers in conventional friction reducing devices have only one rotational degree of freedom, are poorly a...
