Technical Field
[0001] The utility model relates to the technical field of roller fairleads, in particular to a ship roller fairlead which is convenient for applying wear-resistant coating to a cable. Background Art
[0002] A ship fairlead, also known as a "cable fairlead" or "cable hook", is a key cable guiding device used when a ship berths. Its main function is to guide the cable to pass through or change direction to protect the cable from abrasion. A roller fairlead is a fairlead composed of several independent rollers arranged side by side, which is divided into a closed type and an open type. According to the number of its rollers, common ones include double-roller, triple-roller and quadruple-roller fairleads, etc. It can guide several cable ropes at the same time, and its quality is smaller than that of a fairlead with rollers, and it is mostly used on large and medium-sized ships.
[0003] In view of the above related technologies, the inventor found that when the roller fairlead guides the cable to change the transmission direction, there is a large friction between the cable and the roller fairlead. Therefore, a wear-resistant coating such as polyurethane needs to be applied to the surface of the cable to enhance the wear resistance of the cable. Generally, workers manually apply the wear-resistant coating on the surface of the cable. Such an application method increases the labor intensity of workers and reduces the work efficiency. Content of the Utility Model
[0004] The main technical problem to be solved by the utility model is to provide a ship roller fairlead which is convenient for applying wear-resistant coating to a cable. The transmitted cable drives the V-shaped guide roller assembly to rotate, and the V-shaped guide roller assembly drives the wear-resistant coating application cylinder to rotate through a transmission mechanism, so as to apply the liquid of the wear-resistant coating on the cable, reducing the labor intensity of workers and improving the work efficiency.
[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a ship roller fairlead which is convenient for applying wear-resistant coating to a cable, including: a mounting base, both ends of the upper plane of the mounting base are respectively connected with a V-shaped guide roller assembly, the V-shaped guide roller assemblies are arranged diagonally, a wear-resistant coating application cylinder is respectively arranged on one side of the V-shaped guide roller assembly, a feeding tank assembly for spraying liquid onto the outer circumferential surface thereof is respectively arranged above the wear-resistant coating application cylinder, and further includes two transmission mechanisms, and the V-shaped guide roller assembly drives the wear-resistant coating application cylinder to rotate in the reverse direction through the transmission mechanism;
[0006] The wear-resistant coating application cylinder includes a support shaft, a transition cylinder, and a flexible application ring sleeved on the transition cylinder. The transition cylinder is sleeved and connected to the support shaft. The cross-section of the flexible application ring is trapezoidal and extends into the annular V-shaped groove of the V-shaped guide roller assembly. It also includes a first L-shaped plate connected to the mounting base. The upper end of the support shaft passes through the first L-shaped plate and is rotatably connected thereto. The lower end of the support shaft passes through the mounting base and is rotatably connected thereto.
[0007] By adopting the above technical solution, during use, the roller fairlead is installed on the hull. The cable changes the transmission direction after passing around the V-shaped guide roller assemblies at both ends of the mounting base. When the cable is transmitted, it drives the V-shaped guide roller assemblies to rotate. The V-shaped guide roller assemblies drive the wear-resistant coating application cylinder to rotate in the reverse direction through the transmission mechanism. Since the cable passes through the annular V-shaped groove of the V-shaped guide roller assembly and elastically rolls in contact with the flexible application ring on the wear-resistant coating application cylinder, the feeding box assembly conveys the liquid of the wear-resistant coating to the upper inclined surface of the flexible application ring, and the liquid of the wear-resistant coating then flows to the outer circular surface with the largest diameter. The flexible application ring applies the liquid of the wear-resistant coating on the outer surface of the cable, eliminating the need for workers to manually apply the liquid of the wear-resistant coating on the outer surface of the cable, reducing the labor intensity of the workers and improving the work efficiency. Since the outer surface of the cable is elastically in contact with the wear-resistant coating application cylinders at both ends of the mounting base, the entire outer surface of the cable is coated with the liquid of the wear-resistant coating. The cable is then transmitted to an external drying oven for rapid drying. The wear-resistant coating plays a protective role for the cable and extends the service life of the cable.
[0008] In a preferred example of the present utility model, it can be further configured as follows: The V-shaped guide roller assembly includes a V-shaped guide roller and a fixed shaft. The V-shaped guide roller is sleeved and connected to the fixed shaft. It also includes a second L-shaped plate connected to the mounting base. The upper end of the fixed shaft passes through the second L-shaped plate and is rotatably connected thereto. The lower end of the fixed shaft passes through the mounting base and is rotatably connected thereto.
[0009] By adopting the above technical solution, after the cable passes around the annular V-shaped groove of the V-shaped guide roller, the transmission direction can be changed to achieve the purpose of guiding.
[0010] In a preferred example of the present utility model, it can be further configured as follows: The transmission mechanism includes a large external gear ring and a small external gear ring. The large external gear ring is meshed and connected with the small external gear ring. The large external gear ring is sleeved and connected to the outer circle at the upper end of the transition cylinder. The small external gear ring is sleeved and connected to the outer circle of the fixed shaft. When the small external gear ring drives the large external gear ring to rotate, the linear velocity of the smallest outer circular surface of the V-shaped guide roller is equal to the linear velocity of the largest outer circular surface of the flexible application ring.
[0011] By adopting the above technical solution, when the cable is transmitted, it drives the V-shaped guiding roller to rotate. Since the small external gear ring drives the large external gear ring to rotate, the linear velocity of the minimum outer circular surface of the V-shaped guiding roller is equal to the linear velocity of the maximum outer circular surface of the flexible coating ring, so that the transmission speed of the cable is equal to the linear velocity of the maximum diameter outer circle of the flexible coating ring, thereby reducing the friction between the cable and the flexible coating ring and prolonging the service life of the flexible coating ring.
[0012] In a preferred embodiment of the present utility model, it can be further configured that: the feeding box assembly includes a U-shaped seat and a liquid storage tank connected to its upper plane. The U-shaped seat is connected to the upper plane of the first L-shaped plate. The side of the liquid storage tank is connected to a discharge pipe. The outer end of the discharge pipe is connected to an infusion pipe. The end of the infusion pipe away from the discharge pipe is connected to a spray head. The spraying direction of the spray head points to the upper inclined surface of the flexible coating ring. A switching valve is connected to the discharge pipe.
[0013] By adopting the above technical solution, the liquid for the wear-resistant coating is stored in the liquid storage tank. After operating the switching valve, the liquid for the wear-resistant coating flows through the discharge pipe, the infusion pipe and the spray head in sequence and reaches the upper inclined surface of the flexible coating ring, achieving the purpose of providing the liquid for the wear-resistant coating.
[0014] In a preferred embodiment of the present utility model, it can be further configured that: the feeding box assembly further includes an L-shaped fixing plate. One end of the L-shaped fixing plate is connected to the V-shaped guiding roller assembly, and the other end of the L-shaped fixing plate is connected to the outer circular surface of the infusion pipe.
[0015] By adopting the above technical solution, through the use of the L-shaped fixing plate, it is convenient to fix the infusion pipe, so that the liquid for the wear-resistant coating flowing out of the spray head can flow to the upper inclined surface of the flexible coating ring.
[0016] In a preferred embodiment of the present utility model, it can be further configured that: the flexible coating ring is made of wear-resistant sponge.
[0017] By adopting the above technical solution, since the flexible coating ring is made of wear-resistant sponge, the flexible coating ring can inhale the liquid for the wear-resistant coating and then apply it on the outer surface of the cable, enhancing the uniformity of the application of the liquid for the wear-resistant coating.
[0018] In summary, the present utility model includes at least one of the following beneficial technical effects:
[0019] The transmitted cable drives the two V-shaped guiding roller assemblies to rotate. The V-shaped guiding roller assemblies drive the corresponding wear-resistant coating application cylinders to rotate through the transmission mechanism, thereby coating the liquid for the wear-resistant coating on the outer surface of the cable, reducing the labor intensity of workers, improving work efficiency, and the wear-resistant coating plays a role in protecting the cable and prolonging the service life of the cable.

[0032] The wear-resistant coating application cylinder 30 includes a support shaft 31, a transition cylinder 32, and a flexible coating ring 33 sleeved on the transition cylinder 32.

[0034] The transmission mechanism 50 includes a large external gear ring 51 and a small external gear ring 52. The large external gear ring 51 is meshed and connected with the small external gear ring 52. The large external gear ring 51 is sleeved and connected to the outer circle of the upper end of the transition cylinder 32, and the small external gear ring 52 is sleeved and connected to the outer circle of the fixed shaft 22.

[0036] The implementation principle of this embodiment is as follows: When in use, the roller fairlead is installed on the hull. The cable changes its transmission direction after passing around the V-shaped guiding roller assemblies 20 at both ends of the mounting base 1. When the cable is transmitted, it drives the V-shaped guiding roller assemblies 20 to rotate. The V-shaped guiding roller assemblies 20 drive the wear-resistant coating application cylinder 30 to rotate in the reverse direction through the transmission mechanism 50. Since the cable passes through the annular V-shaped groove of the V-shaped guiding roller assemblies 20 and is in elastic rolling contact with the flexible coating application ring 33 on the wear-resistant coating application cylinder 30, the feed box assembly 40 transports the liquid of the wear-resistant coating to the upper inclined surface of the flexible coating application ring 33, and the liquid of the wear-resistant coating then flows to the outer circumferential surface with the maximum diameter.

Since the outer surface of the cable is in elastic contact with the wear-resistant coating application cylinders 30 at both ends of the mounting base 1, the entire outer surface of the cable is coated with the liquid of the wear-resistant coating. The cable is then transmitted to an external drying oven for rapid drying. The wear-resistant coating plays a protective role for the cable and extends the service life of the cable.
