Description

Technical Field

[0001] The utility model relates to the field of fairlead devices, and specifically relates to a marine roller fairlead that is convenient for maintenance. Background Technique

[0002] A roller fairlead is an important ship equipment used to guide and restrict the direction of the cable to protect the cable from abrasion.

[0003] The roller fairlead plays an indispensable role in the process of ship berthing and mooring. It precisely guides the cable, ensuring that the cable will not be damaged due to friction, and at the same time protecting the structural integrity of the ship and the dock.

[0004] When the roller fairlead is in use, the outside of the roller is subject to friction and seawater erosion for a long time, which easily causes wear on the outer surface of the roller. The worn outer surface will in turn wear the cable, which is likely to reduce the strength of the cable. Moreover, when the roller is damaged after long-term use, it cannot be replaced and needs to be replaced as a whole, wasting resources. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a marine roller fairlead that is convenient for maintenance to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A marine roller fairlead that is convenient for maintenance, including a support frame, a horizontal roller, and a vertical roller. A first disassembly mechanism for conveniently disassembling the horizontal roller is arranged between the horizontal roller and the support frame, and a second disassembly mechanism for conveniently disassembling the vertical roller is arranged between the vertical roller and the support frame. Protection mechanisms for protecting the rollers are arranged on both the horizontal roller and the vertical roller. The first disassembly mechanism includes a first groove, a first arc-shaped plate, and a first screw. The first groove is opened on one side of the support frame. The first arc-shaped plate is closely attached to one side of the support frame. The first screw passes through the first arc-shaped plate through threads and then penetrates into the interior of the support frame. When in use, the position of the horizontal roller is restricted by the first arc-shaped plate. When disassembly is required, rotate the first screw to disassemble the first arc-shaped plate, and then the horizontal roller can be disassembled along the first groove, facilitating the disassembly and replacement work of the horizontal roller.

[0007] Preferably, the second disassembly mechanism includes a second groove, a second arc-shaped plate, and a second screw. The second groove is opened on the support frame. The second arc-shaped plate is fixed on the support frame through the second screw. The position of the vertical roller is restricted by the second arc-shaped plate. When disassembly is required, at this time, disassemble the second screw to disassemble the second arc-shaped plate, and thus the vertical roller can be disassembled through the second groove, facilitating the replacement work of the vertical roller.

[0008] Preferably, the protection mechanism includes a protective pad, a limit cover plate, threads, and screw holes. The protective pad is disposed around the outer side of the vertical roller. The threads are formed on the outer side of the vertical roller. The screw holes are formed at the center position of the limit cover plate. The limit cover plate is installed on the outer side of the threads through the screw holes. After the protective pad is installed, the limit cover plate is rotated at this time, so that the limit cover plate moves downward along the threads, thereby limiting the upper and lower sides of the protective pad to prevent the protective pad from moving up and down along the vertical roller, and protecting the vertical roller through the protective pad. When the protective pad is worn, it can be directly replaced, thus preventing the cable from being damaged at the worn position.

[0009] Preferably, there are two transverse rollers, which are symmetrically and movably installed on one side of the support frame.

[0010] Preferably, there are two vertical rollers, which are movably installed on both sides of the support frame.

[0011] Preferably, after the protective pad is wound, the mutually contacting positions of the protective pad are fixed by bonding.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the present invention is in use, the position of the transverse roller is restricted by the first arc-shaped plate. When it needs to be disassembled, the first screw is rotated, and then the first arc-shaped plate can be disassembled. After that, the transverse roller can be disassembled along the first groove body, which facilitates the disassembly and replacement work of the transverse roller;

[0014] The present invention restricts the position of the vertical roller through the second arc-shaped plate. When it needs to be disassembled, the second screw is disassembled at this time, and then the second arc-shaped plate can be disassembled. In this way, the vertical roller can be disassembled through the second groove body, which facilitates the replacement work of the vertical roller;

[0015] After the protective pad is installed in the present invention, the limit cover plate is rotated at this time, so that the limit cover plate moves downward along the threads, thereby limiting the upper and lower sides of the protective pad to prevent the protective pad from moving up and down along the vertical roller, and protecting the vertical roller through the protective pad. When the protective pad is worn, it can be directly replaced, thus preventing the cable from being damaged at the worn position. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a marine roller fairlead that is easy to maintain, including a support frame 1, a horizontal roller 2, and a vertical roller 3. There are two horizontal rollers 2, which are symmetrically and movably installed on one side of the support frame 1. There are two vertical rollers 3, which are movably installed on both sides of the support frame 1. There is a first disassembly mechanism for conveniently disassembling the horizontal roller 2 between the horizontal roller 2 and the support frame 1, and a second disassembly mechanism for conveniently disassembling the vertical roller 3 between the vertical roller 3 and the support frame 1. There is a protection mechanism for protecting the rollers on both the horizontal roller 2 and the vertical roller 3. The first disassembly mechanism includes a first groove 4, a first arc plate 5, and a first screw 6. The first groove 4 is opened on one side of the support frame 1. The first arc plate 5 is closely attached to one side of the support frame 1. The first screw 6 passes through the first arc plate 5 through the thread and then penetrates into the interior of the support frame 1. When in use, the position of the horizontal roller 2 is restricted by the first arc plate 5. When disassembly is required, rotate the first screw 6 to disassemble the first arc plate 5, and then the horizontal roller 2 can be disassembled along the first groove 4, facilitating the disassembly and replacement work of the horizontal roller 2.

[0024] The second disassembly mechanism includes a second groove 7, a second arc plate 8, and a second screw 9. The second groove 7 is opened on the support frame 1. The second arc plate 8 is fixed to the support frame 1 by the second screw 9. The position of the vertical roller 3 is restricted by the second arc plate 8. When disassembly is required, at this time, disassemble the second screw 9 to disassemble the second arc plate 8, and thus the vertical roller 3 can be disassembled through the second groove 7, facilitating the replacement work of the vertical roller 3.

[0025] The protection mechanism includes a protective pad 11, a limit cover plate 10, a thread 12 and a screw hole 13. The protective pad 11 surrounds the outside of the vertical roller 3. After the protective pad 11 surrounds, the contact positions of the protective pad 11 are fixed by bonding. The thread 12 is opened on the outside of the vertical roller 3, and the screw hole 13 is opened at the center position of the limit cover plate 10. The limit cover plate 10 is installed outside the thread 12 through the screw hole 13. After the installation of the protective pad 11 is completed, at this time, the limit cover plate 10 is rotated so that the limit cover plate 10 moves downward along the thread 12, thereby limiting the upper and lower sides of the protective pad 11 to prevent the protective pad 11 from moving up and down along the vertical roller 3, and protecting the vertical roller 3 through the protective pad 11. When the protective pad 11 is worn, it can be directly replaced, thus preventing the cable from being damaged at the worn position.

[0026] Working principle: When in use, the position of the transverse roller 2 is restricted by the first arc-shaped plate 5. When it needs to be disassembled, the first screw 6 is rotated to disassemble the first arc-shaped plate 5, and then the transverse roller 2 can be disassembled along the first groove body 4, which is convenient for the disassembly and replacement of the transverse roller 2; the position of the vertical roller 3 is restricted by the second arc-shaped plate 8. When it needs to be disassembled, at this time, the second screw 9 is disassembled to disassemble the second arc-shaped plate 8, and thus the vertical roller 3 can be disassembled through the second groove body 7, which is convenient for the replacement of the vertical roller 3; after the installation of the protective pad 11 is completed, at this time, the limit cover plate 10 is rotated so that the limit cover plate 10 moves downward along the thread 12, thereby limiting the upper and lower sides of the protective pad 11 to prevent the protective pad 11 from moving up and down along the vertical roller 3, and protecting the vertical roller 3 through the protective pad 11. When the protective pad 11 is worn, it can be directly replaced, thus preventing the cable from being damaged at the worn position.
