Description

Technical Field

[0001] This application relates to the field of marine roller technology, and more particularly to the field of polymer integral marine roller technology. Background Technology

[0002] Marine rollers are crucial equipment for ship mooring and navigation safety. As a key component connecting mooring lines to the vessel, guide rollers must withstand high-intensity operations to ensure smooth mooring line deployment and minimize wear. They are typically made of high-quality steel, possessing corrosion and wear resistance properties. Through precise design, they ensure smooth and efficient operation. Furthermore, advanced technologies such as braking and traction are incorporated to enhance the safety and stability of vessels operating in complex waters.

[0003] CN220054071U discloses a marine cable guide roller, comprising a roller body rotatably connected to the outside of a connecting shaft via bearings, and a rubber sleeve fitted over the outside of the roller body. The rubber sleeve has several countersunk holes evenly distributed circumferentially, extending radially through the rubber sleeve. The outer wall of the roller body has threaded holes corresponding to and communicating with the countersunk holes. Each countersunk hole contains a connecting bolt, the head of which abuts against the inner wall of the countersunk hole, and the threaded section of the bolt is threaded into the threaded hole. The rubber sleeve on the outside of the roller body increases the friction between the marine cable guide and the roller guide. Thus, during the pulling of the marine cable guide, the cable guide can drive the roller body to rotate, making it less prone to relative slippage between the cable guide and the roller body, and reducing the wear of the marine cable guide.

[0004] Despite numerous optimizations in structural design and material application to enhance wear resistance and functionality, existing polymer-based marine rollers still face the serious challenge of corrosion resistance in harsh environments such as the ocean. The salinity, humidity, and potential other chemicals in the marine environment can easily corrode the rollers, affecting their performance and service life. Therefore, further improving the corrosion resistance of rollers has become a critical issue that urgently needs to be addressed. Utility Model Content

[0005] To address the problem of poor corrosion resistance of existing marine rollers in marine environments, this application provides a polymer integral marine roller.

[0006] This application provides a polymer integral marine roller, which adopts the following technical solution:

[0007] A polymer integral marine roller includes a roller body, a roller seat, and a roller shaft. The roller shaft is vertically installed at the middle position of the upper end face of the roller seat, and the roller body is sleeved on the outside of the roller shaft. The roller body is characterized in that the roller body is divided into two layers: the inner layer is a metal iron roller, and the outer layer is a composite layer.

[0008] By adopting the above technical solution, the roller body, roller seat and roller shaft are designed as a whole, and with the comprehensive protection of the composite layer, the corrosion resistance of the roller in the marine environment is improved, the overall structural strength of the roller is enhanced, and the safety and reliability of ship operations are improved.

[0009] More preferably, the composite layer consists of a hydrophobic layer, a composite reinforcement layer, and a wear-resistant layer arranged sequentially from the inside out.

[0010] By adopting the above technical solutions, waterproofing, corrosion resistance, enhanced hardness, and wear resistance are organically combined to make the performance of marine guide rollers more balanced and superior.

[0011] More preferably, the thickness of the hydrophobic layer is 380-420 nm.

[0012] By employing the above technical solution, the inner layer is protected from seawater corrosion. Even in humid or rainy marine environments, the rollers can maintain a dry surface, reducing the risk of corrosion and extending their service life.

[0013] More preferably, the thickness of the composite reinforcement layer is 650-700 nm.

[0014] By adopting the above technical solutions, the hardness of the rollers can be increased, thereby enhancing their impact resistance and wear resistance.

[0015] More preferably, the wear-resistant layer thickness is 220-280 nm.

[0016] By adopting the above technical solution, the friction and wear between the roller and the cable are significantly reduced, energy loss is reduced, and the smoothness of the roller surface is maintained to ensure the smooth passage of the cable.

[0017] More preferably, the surface roughness of the wear-resistant layer is less than Ra0.10.

[0018] By adopting the above technical solutions, the resistance and energy consumption during roller operation are reduced, cable wear is also reduced, and the efficiency and service life of the entire cable guiding system are improved.

[0019] More preferably, the annular surface of the roller body is integrally formed, and the diameter of the opening at the upper end of the roller body is smaller than that at the lower end.

[0020] By adopting the above technical solution, the roller body's ability to withstand heavy loads is enhanced. The reduction in the diameter of the upper opening allows the roller to more effectively distribute the load to the connection between the roller body and the roller shaft, as well as the fixing point between the roller seat and the ship's deck, when subjected to a vertically downward heavy load, thereby reducing the risk of damage caused by local overload.

[0021] More preferably, the arc of the waist contact surface of the roller body is in the range of 1.0 radians to 1.3 radians.

[0022] By adopting the above technical solutions, the direct impact between the roller and the contact surface during the rolling process is reduced, thereby reducing operating noise, effectively distributing the load, reducing single-point wear, and extending the service life of the roller.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. By attaching a composite layer to the surface of the polymer roller body, the wear-resistant layer significantly improves the roller's wear resistance. The hydrophobic layer design reduces direct contact between the roller body and these substances, thereby enhancing the roller's corrosion resistance and preventing rust or corrosion in humid, high-salt marine environments. The composite reinforcement layer provides additional structural support and strength enhancement to the roller. This makes the roller more stable and reliable under heavy loads or complex stresses, reducing the risk of failure due to deformation or damage.

[0025] 2. By differentiating the upper and lower opening diameters of the roller body, the overall weight and space occupied by the roller are reduced, making it easier for staff to operate. On the other hand, the center of gravity of the roller is adjusted to make it more stable on the roller seat, reducing the risk of rolling or sliding caused by lateral forces or impacts.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This application discloses a polymer integral marine roller, with reference to... Figure 1The roller includes a roller body 1, a roller seat 2, and a roller shaft 3. The roller shaft 3 is vertically installed at the middle of the upper end face of the roller seat 2. The roller body is fitted onto the outside of the roller shaft 3. In use, the roller body 1 is fitted onto the roller shaft 3. The roller shaft 3 adds lateral axial force to the marine roller to control the traction or release of the cable. The roller seat 2 is fixed to the deck of the ship to ensure that the tension borne by the roller is stable.

[0031] More preferably, the roller body 1 is divided into two layers: an inner layer of metal iron roller and an outer composite layer. The composite layer, from the inside out, consists of a hydrophobic layer 4, a composite reinforcing layer 5, and a wear-resistant layer 6. This three-layer design provides comprehensive, multi-layered protection for the marine guide roller, significantly improving its corrosion resistance, structural strength, and wear resistance.

[0032] More preferably, the hydrophobic layer 4, as the innermost layer of the polymer coating, is closely attached to the surface of the roller body. The thickness of the hydrophobic layer is controlled between 380nm and 420nm. Its hydrophobic properties effectively isolate seawater from direct contact with the roller substrate, thereby effectively preventing corrosion.

[0033] More preferably, the composite reinforcing layer 5 serves as the intermediate layer of the polymer coating, located between the hydrophobic layer 4 and the wear-resistant layer 6, and acts as a connector between the inner and outer layers. The thickness of the composite reinforcing layer is 650nm-700nm, which enhances the overall strength and toughness of the coating, effectively disperses and absorbs the stress and impact experienced by the roller during rolling, and ensures that the composite reinforcing layer can fully bond with the roller body to cope with external washing.

[0034] More preferably, the wear-resistant layer 6, as the outermost layer of the polymer coating, has a thickness of 220-280 nm, which reduces the driving force and energy consumption required for the marine cable roller during the rolling process, and also reduces the heat and wear particles generated by friction, thus extending the service life of the marine roller and cable.

[0035] More preferably, the surface roughness of the wear-resistant layer 6 is less than Ra0.10, which makes the roller roll more smoothly, further reducing the resistance and vibration caused by surface roughness, and improving the stability and efficiency of the system.

[0036] More preferably, the annular surface of the roller body 1 is integrally molded, and the opening diameter at the upper end of the roller body 1 is smaller than that at the lower end, reducing the overall weight of the roller so that it can be moved or installed more easily. In some space-constrained environments, it is easier for operators to use. It also helps to improve the stability of the roller during operation when it is subjected to certain lateral forces or impacts.

[0037] More preferably, the arc of the waist contact surface of the roller body 1 is in the range of 1.0 radians to 1.3 radians, thereby reducing frictional resistance and vibration during the rolling process and improving the smoothness and efficiency of rolling.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
