Description

Technical Field

[0001] The utility model relates to the field of mooring auxiliary equipment, and particularly relates to a wear-resistant roller fairlead for shore mooring. Background Technique

[0002] A fairlead belongs to a term in ship engineering and is a device that can be used to guide cables from any direction, also known as a "cable fairlead clamp" or "cable fairlead hook". Fairleads are widely used to lead cables from a certain location on the ship's side or the dock side and are common ship supplies. They are usually installed at the end of the ship's deck and are also called universal fairleads. The design feature of this kind of fairlead is that rollers or rollers are provided on the left and right and up and down of the hole. This structure greatly reduces the friction when the cable passes through, thus effectively protecting the cable and avoiding serious wear.

[0003] At present, there are various types and models of fairleads on the market, which match the size of the cable, and the sizes of the fairleads are also different. For example, the Chinese patent with the application number: CN202323102826.2, the specific content is: a ship roller fairlead, including a fixed base; a horizontal fairlead wheel is rotatably connected inside the fixed base. The above patent is a typical fairlead, but the roller structure adopted by the fairlead has relatively high requirements for the cable. The edges and corners of the roller are easy to cut the cable, and at the same time, the friction protection for the cable is insufficient, and the cable wears quickly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wear-resistant roller fairlead for shore mooring to solve the problems of insufficient friction protection for the cable and rapid cable wear existing in the existing fairleads as mentioned in the above background technique.

[0005] The technical solution of the utility model is realized as follows: a wear-resistant roller fairlead for shore mooring, two vertically arranged rollers with the same internal structure are installed on the frame, and two vertically arranged vertical rollers with the same structure as the vertically arranged rollers and perpendicular to them are arranged on the side of the vertically arranged rollers and inside the frame;

[0006] The vertically arranged roller includes a fixed axis for connecting with the frame, an outer sleeve is rotatably installed outside the fixed axis, a plurality of self-lubricating balls are embedded in the outer sleeve, a sealed cavity is formed inside the outer sleeve, the sealed cavity is filled with lubricating liquid, and a one-way valve communicating with the lubricating liquid is installed on the top of the outer sleeve.

[0007] Preferably, an installation limit block is arranged on the fixed axis.

[0008] Preferably, a gasket is arranged between the fixed axis and the outer sleeve.

[0009] Preferably, a diversion pipe is installed on the one-way valve, and the diversion pipe is a metal corrugated pipe.

[0010] Preferably, the center of the self-lubricating ball is embedded in the outer sleeve.

[0011] Adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] For this kind of wear-resistant shore mooring roller fairlead, using rollers as the main fairlead body, it can be generally applicable to ropes of various sizes, with good general applicability. At the same time, the present utility model can also provide lubrication protection for the rope while fairleading, reduce the friction between the fairlead and the rope, thereby reducing the wear of the rope and improving the service life of the rope.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all 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 belong to the scope of protection of the present utility model.

[0020] Refer toFigures 1-4 , a wear-resistant roller fairlead for shore mooring, comprising a frame 1, on which two vertically arranged rollers 2 with the same internal structure are installed. On the side of the vertical roller 2, two perpendicular rollers 3 which are installed inside the frame 1 and have the same structure as the vertical roller 2 and are perpendicularly arranged are provided;

[0021] The vertical roller 2 includes a fixed axis 201 for connecting with the frame 1. An outer sleeve 204 is rotatably installed outside the fixed axis 201. A plurality of self-lubricating balls 205 are embedded in the outer sleeve 204. A sealed cavity 206 is formed inside the outer sleeve 204. A lubricating fluid 207 is filled in the sealed cavity 206. A one-way valve 208 communicating with the lubricating fluid 207 is installed at the top of the outer sleeve 204.

[0022] Refer to Figure 3 and Figure 4 , an installation limit block 202 is arranged on the fixed axis 201. Such a setting can use the installation limit block 202 to provide an installation reference for the vertical roller 2, improving the stability and convenience of the installation of the vertical roller 2.

[0023] Refer to Figure 3 and Figure 4 , a gasket 203 is arranged between the fixed axis 201 and the outer sleeve 204. Such a setting can reduce the friction force when the fixed axis 201 and the outer sleeve 204 rotate relative to each other through the gasket 203, thereby reducing the loss of the fixed axis 201 and the outer sleeve 204 and prolonging the service life of the device.

[0024] Refer to Figure 3 and Figure 4 , a diversion pipe 209 is installed on the one-way valve 208. The diversion pipe 209 is a metal corrugated pipe. Such a setting is convenient for supplementing the lubricating fluid 207 into the vertical roller 2 and the perpendicular roller 3 through the diversion pipe 209 via the one-way valve 208 at any time when needed.

[0025] Refer to Figure 4 , the ball center of the self-lubricating ball 205 is embedded in the outer sleeve 204. Such a setting can ensure that the self-lubricating ball 205 can freely rotate in the outer sleeve 204 without falling off. Thus, while the self-lubricating ball 205 rolls, the self-lubricating ball 205 takes out the lubricating fluid 207 in the sealed cavity 206 and smears it on the cable, reducing the friction force between the cable and the vertical roller 2 and the perpendicular roller 3, thereby playing a role in protecting the cable.

[0026] Working principle: When using this device, first install the vertical roller 2 and the perpendicular roller 3 into the frame 1 of the frame respectively, and inject lubricating fluid 207 into the vertical roller 2 and the perpendicular roller 3. Then close the one-way valve 208, and pass the cable through the middle positions of the vertical roller 2 and the perpendicular roller 3. When the cable slides inside the vertical roller 2 and the perpendicular roller 3, while driving the vertical roller 2 and the perpendicular roller 3 to rotate, the self-lubricating balls 205 on the surfaces of the vertical roller 2 and the perpendicular roller 3 roll along. While the self-lubricating balls 205 are rolling, the self-lubricating balls 205 carry out the lubricating fluid 207 in the sealed cavity 206 and smear it on the cable, reducing the friction between the cable and the vertical roller 2 and the perpendicular roller 3, thereby playing a role in protecting the cable. At the same time, the lubricating fluid 207 can also absorb the heat generated when the vertical roller 2 and the perpendicular roller 3 rub against the cable, improving the protection effect on the cable.

For example, "connection" can be a fixed connection or indirectly through an intermediate component without affecting the relationship between components and technical effects, or it can be an integral connection or a partial connection.
