Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a cable guide device for ships and the ship. Background Art

[0002] During the mooring process of a ship, due to the influence of factors such as tides, wind and waves, the cable and the fairlead will undergo reciprocating relative displacement. At the same time, due to the uneven surface of the fairlead, the cable will be greatly worn, reducing the service life of the cable.

[0003] In order to solve the above problems, in the prior art, the wear of the cable is reduced by adding an anti-wear pad to the inner wall of the cable guide hole. The common installation method is generally to splice multiple anti-wear pads and install them on the inner wall of the cable guide hole with screws. This installation method results in gaps between the anti-wear pads and screw installation holes. The gaps and holes will still have a certain impact on the cable. Therefore, it still needs to be improved. Utility Model Content

[0036] Embodiment 1

[0037] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a cable guide device for a ship, which includes a fixing seat 10 and an anti-wear pad 20. The fixing seat 10 is fixedly arranged on the deck or side plate of the ship, and the fixing seat 10 is provided with a cable guide hole 11 and a limiting portion; the outer wall shape of the anti-wear pad 20 is adapted to the inner wall shape of the cable guide hole 11, the anti-wear pad 20 is arranged in the cable guide hole 11, and the outer wall of the anti-wear pad 20 and the inner wall of the cable guide hole 11 are in contact, and the limiting portion can limit the movement of the anti-wear pad 20 along the axial direction of the cable guide hole 11.

[0038] The ship's cable guide device arranges the outer wall of the anti-wear liner 20 to match the inner wall of the cable guide hole 11, so that when the anti-wear liner 20 is connected to the cable guide hole 11, the outer wall of the anti-wear liner 20 can fit with the inner wall of the cable guide hole 11, and the limiting portion can limit the movement of the anti-wear liner 20 along the axial direction of the cable guide hole 11, avoiding the use of screws to install the anti-wear liner 20, so that the anti-wear liner 20 can be fixed in the cable guide hole 11 and can completely fit with the cable guide hole 11, and the cable is passed through the through hole 21 of the anti-wear liner 20, thereby reducing the wear of the cable and increasing the service life of the cable.

[0039] Optionally, the limiting portion includes two annular bosses 12, which are fixedly arranged at both ends of the fixing seat 10 along the axial direction of the cable guide hole 11; annular limiting plates 22 are arranged at both ends of the anti-wear pad 20 along the axial direction of the cable guide hole 11, and the annular limiting plates 22 extend outward in a direction perpendicular to the axis of the cable guide hole 11. When the anti-wear pad 20 is installed in the cable guide hole 11, the two annular bosses 12 are located between the two annular limiting plates 22, and the two annular limiting plates 22 can respectively abut against the two annular bosses 12. This structure enables the annular limiting plates 22 at both ends and the corresponding annular bosses 12 to abut against each other when the cable reciprocates and applies force to the anti-wear pad 20, which can effectively prevent the anti-wear pad 20 from slipping out of the cable guide hole 11.

[0040] In order to further improve the installation firmness of the anti-wear pad 20, a first inclined surface 121 is provided on the inner side of the annular boss 12, and the cross-sectional size of the first inclined surface 121 gradually decreases from the fixing seat 10 to the annular boss 12; second inclined surfaces 23 are provided at both ends of the anti-wear pad 20, and the cross-sectional size of the second inclined surface 23 gradually decreases from the anti-wear pad 20 to the annular limit plate 22. When the anti-wear pad 20 is installed in the fairlead hole 11, the two annular bosses 12 abut against the two annular limit plates 22 respectively, and the two first inclined surfaces 121 can abut against the corresponding second inclined surfaces 23 respectively. This structure further improves the installation firmness of the anti-wear pad 20 by having the two annular bosses 12 abut against the two annular limit plates 22 respectively, and the two first inclined surfaces 121 abut against the corresponding second inclined surfaces 23.

[0041] Optionally, the fixing seat 10 is a casting, which is manufactured by a casting process, which has a simple process and a low production cost. In this embodiment, the fixing seat 10 is a cast iron part.

[0042] Optionally, the anti-wear pad 20 is a cast part, which is cast in the cable guide hole 11 using a composite material so that the anti-wear pad 20 can completely fit with the cable guide hole 11 with a high degree of matching. The anti-wear pad 20 is integrated with the fixing seat 10 without seams or holes, which can better protect the cable and reduce wear.

[0043] During the casting process of the anti-wear pad 20, the fixing seat 10 is used as the outer mold, and the inner mold is designed according to the size of the through hole 21 of the anti-wear pad 20, and then the inner mold is centrally arranged in the fairing hole 11, and a molding gap is formed between the inner wall of the fairing hole 11 and the outer wall of the inner mold, and finally the composite material is cast in the molding gap to form the anti-wear pad 20. In this structure, the size of the through hole 21 does not need to be limited by the fairing hole 11, and the size of the inner mold can be adjusted according to the needs of the mooring design, thereby achieving the purpose of adjusting the size of the through hole 21; and during the casting process of the anti-wear pad 20, the inner wall of the fairing hole 11 does not need to be polished and smooth, and the curvature of the curved surface does not need to be controlled, and the gap can be filled by the anti-wear pad 20 during casting and molding, so that the anti-wear pad 20 and the inner wall of the fairing hole 11 can be completely fitted.

When the anti-wear liner 20 is installed in the cable guide hole 11, the plurality of limiting protrusions 13 are inserted into the plurality of limiting grooves 24 one by one, so as to form a good fixation for the anti-wear liner 20 to prevent the anti-wear liner 20 from falling out of the cable guide hole 11, and the limiting protrusions 13 in the structure are hidden inside the anti-wear liner 20 and do not affect the appearance.

[0047] It is understandable that the anti-wear liner 20 can cover the limiting protrusion 13 during the casting process, so that the anti-wear liner 20 forms the limiting groove 24 during the molding process.

[0048] Optionally, the plurality of limiting protrusions 13 are divided into two groups, the two groups of limiting protrusions 13 are arranged at intervals along the axis direction of the fairlead hole 11, and the plurality of limiting protrusions 13 in each group are distributed on the inner wall of the fairlead hole 11 around the axis circumference of the fairlead hole 11. This structure allows the anti-wear liner 20 to be evenly stressed and the dustproof liner to be more firmly installed.

[0049] Furthermore, if Figure 5As shown, the limiting protrusion 13 includes a first plate 131 and a second plate 132 connected perpendicularly to each other, the first plate 131 is fixedly connected to the inner wall of the fairlead hole 11, and the second plate 132 in one group of limiting protrusions 13 and the second plate 132 in another group of limiting protrusions 13 are extended toward each other or extended away from each other; the limiting groove 24 includes a first groove and a second groove connected perpendicularly to each other, the extension direction of the second groove is set corresponding to the extension direction of the second plate 132, the first plate 131 and the second plate 132 are respectively limited in the corresponding first groove and the second groove, and the limiting protrusion 13 in this structure is reasonably designed and can better limit the anti-wear liner 20. In this embodiment, the second plate 132 in one group of limiting protrusions 13 and the second plate 132 in another group of limiting protrusions 13 are extended toward each other.

[0050] Optionally, the limiting protrusion 13 can be made of angle steel.
