Description

Technical Field

[0001] The utility model relates to the technical field of ship roller sheaths, in particular to a marine polymer roller sheath. Background Art

[0002] A fairlead roller refers to a mooring appliance used to guide a cable through or change its direction to protect the cable from abrasion.

[0003] The fairlead roller for guiding mooring cables is a special part used for mooring when a ship docks. The known fairlead roller is vertically installed on the bow and stern deck near the side of the ship. When mooring, the cable first passes through the fairlead roller and then is fixed to a bollard or a winch. The fairlead roller is used for cable guiding and at the same time protects the cable from abrasion.

[0004] A protective sleeve is usually sleeved on the surface of the fairlead roller. The protective sleeve has high wear resistance and is used to protect the roller and the cable from abrasion. When the ship docks at the wharf, the cable pulls the hull through the running surface of the fairlead roller, preventing the rope from being worn during the drift of the ship, and playing the role of cable guiding and cable protection.

[0005] In the related art, the protective sleeve on the surface of the roller is often severely worn during long-term use, and at the same time, the cable is also severely worn, which seriously affects the safety and economy of ship operation. Summary of the Utility Model

[0006] Aiming at the problems in the related art, the present application discloses a marine polymer roller sheath, which solves the problems that the protective sleeve on the surface of the marine roller is easily worn and the cable is easily worn in the related art.

[0007] To achieve the above object, the present application provides the following technical solutions:

[0008] A marine polymer roller sheath, the shape of the sheath conforms to the outer shape of the roller. The sheath includes a wear-resistant layer and a buffer layer from outside to inside, and a self-lubricating layer is provided on the outer surface of the wear-resistant layer.

[0009] As a further solution of the present application: an anti-slip layer is provided on the inner side surface of the buffer layer.

[0010] As a further solution of the present application: anti-slip protrusions are provided on the inner side surface of the anti-slip layer.

[0011] As a further solution of the present application: an uneven surface is provided between the wear-resistant layer and the buffer layer, and the uneven surface can increase the bonding area between the wear-resistant layer and the buffer layer.

[0012] As a further solution of the present application: reinforcing layers are provided inside both the wear-resistant layer and the buffer layer.

[0013] As a further solution of the present application: The reinforcing layer includes a nylon mesh layer.

[0014] In summary, the beneficial effects of the present application are as follows:

[0015] 1. For the marine polymer roller sheath, the shape of the sheath conforms to the outer shape of the roller. The sheath includes a wear-resistant layer and a buffer layer from the outside to the inside. A self-lubricating layer is provided on the outer surface of the wear-resistant layer. The self-lubricating layer contains tiny lubricant particles, and these lubricant particles are stably stored in the self-lubricating layer. During the friction process between the cable and the protective sheath, due to external force or temperature rise, the lubricant gradually releases from the self-lubricating layer. The released lubricant forms a lubricating film on the friction surface, thus effectively reducing the friction coefficient and wear, effectively protecting the sheath and the cable, reducing the wear rate of the sheath and the cable, and improving the safety and economy of ship operation.

[0016] 2. An anti-slip layer is provided on the inner side of the buffer layer, and anti-slip particles are provided inside the anti-slip layer, which improves the bonding degree between the sheath and the roller and improves the safety of the sheath.

[0017] 3. Anti-slip protrusions are provided on the inner side of the anti-slip layer. The anti-slip protrusions increase the contact area between the anti-slip layer and the roller, improve the bonding degree between the sheath and the roller, and improve the safety of the sheath.

[0018] 4. There are concave and convex surfaces between the wear-resistant layer and the buffer layer. The concave and convex surfaces increase the bonding area between the wear-resistant layer and the buffer layer, improve the bonding degree between the wear-resistant layer and the buffer layer, and improve the safety of the sheath.

[0019] 5. Reinforcing layers are provided inside both the wear-resistant layer and the buffer layer. The reinforcing layer is preferably a nylon mesh layer. The reinforcing layer is embedded inside the wear-resistant layer and the buffer layer, which improves the firmness of the sheath, increases the service life of the sheath, and improves the safety and economy of ship operation.

[0028] To further understand the content, features and effects of the present application, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows:

[0029] As Figure 1 shown:

[0030] A marine polymer roller sheath, the shape of the sheath conforms to the outer shape of the roller, and the sheath can be tightly sleeved outside the roller.

[0031] The sheath is composed of multiple layers. From the outside to the inside, the sheath includes a wear-resistant layer 1 and a buffer layer 2. A self-lubricating layer 3 is provided on the outer surface of the wear-resistant layer 1.

[0032] The wear-resistant layer 1 includes wear-resistant polyurethane, the buffer layer 2 includes wear-resistant rubber, and the protective sleeve is made of wear-resistant material, having good wear resistance and being able to effectively prevent the cable from being worn.

[0033] The self-lubricating layer 3 contains tiny lubricant particles, which are stably stored in the self-lubricating layer 3. During the friction process between the cable and the protective sleeve, due to external forces or temperature rise, the lubricant gradually releases from the self-lubricating layer 3. The released lubricant forms a lubricating film on the friction surface, thereby effectively reducing the friction coefficient and wear, effectively protecting the protective sleeve and the cable, reducing the wear rate of the protective sleeve and the cable, and improving the safety and economy of ship operation.

[0034] The inner side of the buffer layer 2 is provided with an anti-slip layer 4. The anti-slip layer 4 is composed of anti-slip rubber and contains anti-slip particles inside, having high elasticity and anti-slip performance, which can effectively improve the bonding degree between the protective sleeve and the roller.

[0035] In addition, the inner side of the anti-slip layer 4 is provided with anti-slip protrusions 5. The anti-slip protrusions 5 are semi-circular protrusions, and adjacent semi-circular protrusions are in contact with each other. The anti-slip protrusions 5 increase the contact area between the anti-slip layer 4 and the roller, and improve the bonding degree between the protective sleeve and the roller.

[0036] In addition, there is an uneven surface 6 between the wear-resistant layer 1 and the buffer layer 2. The uneven surface 6 can increase the bonding area between the wear-resistant layer 1 and the buffer layer 2, improve the bonding degree between the wear-resistant layer 1 and the buffer layer 2, and improve the safety of the protective sleeve.

[0037] Reinforcing layers 7 are provided inside both the wear-resistant layer 1 and the buffer layer 2. The reinforcing layer 7 is preferably a nylon mesh layer. The nylon mesh layer enhances the wear resistance and tensile strength of the wear-resistant layer 1 and the buffer layer 2, and improves the service life of the protective sleeve.

[0038] In practical applications:

[0039] The protective sleeve includes a wear-resistant layer 1 and a buffer layer 2 from the outside to the inside. The outer surface of the wear-resistant layer 1 is provided with a self-lubricating layer 3. The self-lubricating layer 3 contains tiny lubricant particles, which are stably stored in the self-lubricating layer 3. During the friction process between the cable and the protective sleeve, due to external forces or temperature rise, the lubricant gradually releases from the self-lubricating layer 3. The released lubricant forms a lubricating film on the friction surface, thereby effectively reducing the friction coefficient and wear, effectively protecting the protective sleeve and the cable, reducing the wear rate of the protective sleeve and the cable, and improving the safety and economy of ship operation.

[0040] The inner side of the buffer layer 2 is provided with an anti-slip layer 4. The anti-slip layer 4 is provided with anti-slip particles inside, which improves the bonding degree between the protective sleeve and the roller and improves the safety of the protective sleeve.

[0041] The inner side of the anti-slip layer 4 is provided with anti-slip protrusions 5. The anti-slip protrusions 5 increase the contact area between the anti-slip layer 4 and the roller, and improve the bonding degree between the protective sleeve and the roller.

[0042] There is a concave-convex surface 6 between the wear-resistant layer 1 and the buffer layer 2. The concave-convex surface 6 increases the bonding area between the wear-resistant layer 1 and the buffer layer 2, improves the bonding degree between the wear-resistant layer 1 and the buffer layer 2, and improves the safety of the sheath.

[0043] Reinforcing layers 7 are provided inside both the wear-resistant layer 1 and the buffer layer 2. The reinforcing layer 7 is preferably a nylon mesh layer. The embedding of the reinforcing layer 7 inside the wear-resistant layer 1 and the buffer layer 2 improves the firmness of the sheath, extends the service life of the sheath, and improves the safety and economy of ship operation.

[0044] This new type of roller sheath is made of multiple layers of wear-resistant, anti-aging and self-lubricating materials, which significantly improves the durability and anti-wear performance of the roller sheath, improves the bonding degree between the sheath and the roller, and extends the service life of the sheath; using such a roller sheath can effectively protect the cable, improving the economy and safety of the ship; the design of this fairlead sheath is simple and practical, easy to produce and install, with low cost and long service life, and has a good market prospect.

[0045] Finally, it should be noted that the above disclosure is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The scope of the present application is only limited by the appended claims.
