[0003] A search of CN220054071U discloses a ship cable guide roller, which makes it difficult for relative sliding to occur between the ship cable guide and the roller body, and is not easy to aggravate the wear of the ship cable guide.

[0004] The cable guide roller can extend the service life of the cable guide, but the cable guide roller is directly arranged on the mounting seat. When the cable guide roller needs to be disassembled after long-term use, tools are needed to directly disassemble the mounting seat, which increases the overall complexity of replacement and repair.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0014] As a preferred embodiment of the utility model, the oil outlet holes are arranged in a plurality, and the oil outlet holes are evenly and equidistantly distributed on the outer wall of the cable guide roller.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] According to the utility model, first, the lever is pushed backward, and the lever will drive the second connecting rod to move backward. When the second connecting rod moves, it will drive the installation plug rod to move. When the installation plug rod moves, the spring is squeezed and compressed. At the same time, when the installation plug rod moves, it will drive the first connecting rod to move, thereby synchronously driving the installation plug rod on the other side to move.

[0017] The utility model firstly injects lubricating oil into the oil storage tank provided on the inner wall of the cable guide roller through the oil inlet hole, and seals the oil inlet hole after injecting the lubricating oil. When lubricating the outer wall of the cable guide roller is needed, the electric telescopic rod can be started, and the output end of the electric telescopic rod can drive the rubber push plate to move downward, thereby pushing the air inside the oil storage tank to move downward, and at the same time driving the lubricating oil inside to squeeze the rubber plate. At this time, the rubber plate is squeezed outward by the pressure and deformed, thereby separating from each other to open the oil outlet. After that, the lubricating oil can enter the oil outlet through the oil outlet and flow to the outer wall of the cable guide roller, so as to achieve the purpose of lubricating the outer wall of the cable guide roller.

[0027] Furthermore, there are two mounting rods 314, which are distributed on the left and right inner walls of the mounting groove in a left-right symmetrical structure, so that the left and right sides of the connecting base plate 318 can be positioned synchronously, thereby further improving the load-bearing capacity after installation and improving the stability after installation.

[0028] Furthermore, a socket is provided on the inner wall of the installation groove at the top of the installation turntable 312, and the inner wall of the socket fits snugly with the inner wall of the installation socket 319 and the outer wall of the installation rod 314, so as to ensure the fitting stability of the installation rod 314 after installation.

[0029] The lubrication mechanism 32 includes an oil storage tank opened at the top of the cable guide roller 2, the inner wall of the top of the oil storage tank is fixedly connected to a cover plate 321, the bottom end of the cover plate 321 is fixedly connected to an electric telescopic rod 322, the output end of the electric telescopic rod 322 is fixedly connected to a rubber push plate 323, an oil outlet is opened at the bottom end of the inner wall of the oil storage tank opened at the top of the cable guide roller 2, a rubber plate 324 is fixedly connected to the inner wall of the oil outlet, an oil outlet hole 325 connected to the outer wall of the cable guide roller 2 is opened on the inner wall of the oil outlet, and an oil inlet hole 326 connected to the inner wall of the oil storage tank is opened at the top of the cable guide roller 2.

[0031] Furthermore, a plurality of oil outlet holes 325 are arranged, and the oil outlet holes 325 are evenly and equidistantly distributed on the outer wall of the cable guide roller 2, so that lubricating oil can be applied to the outer wall of the cable guide roller 2 all around at the same time, thereby further improving the smoothness of the cable guide roller 2 during use.

[0032] The implementation principle of a cable guide roller for a floating production storage vessel of this embodiment is as follows: when the cable guide roller 2 needs to be disassembled, first push the lever 317 backward, and the lever 317 will drive the second connecting rod 316 to move backward. When the second connecting rod 316 moves, it will drive the installation plug rod 314 to move. When the installation plug rod 314 moves, the spring 313 is squeezed and compressed. At the same time, when the installation plug rod 314 moves, it will drive the first connecting rod 315 to move, thereby synchronously driving The mounting plug rod 314 on the other side moves, so that the two mounting plug rods 314 will move backward synchronously, thereby disengaging from the mounting hole 319 opened on the inner wall of the mounting turntable 312 and the outer wall of the connecting base plate 318, so that the connecting base plate 318 will be separated from the positioning relationship between the mounting turntable 312, and then the connecting base plate 318 can be taken out upward to disengage from the mounting groove at the top of the mounting turntable 312, and at the same time, the cable guide roller 2 installed on the top of the connecting base plate 318 will be driven to remove the mounting seat 1, completing the disassembly work.

[0033] First, the lubricating oil is poured into the oil storage tank provided on the inner wall of the cable guide roller 2 through the oil inlet hole 326. After the lubricating oil is poured in, the oil inlet hole 326 is sealed. When the outer wall of the cable guide roller 2 needs to be lubricated, the electric telescopic rod 322 can be started, and its output end will drive the rubber push plate 323 to move downward, thereby pushing the air inside the oil storage tank to move downward, and at the same time drive the internal lubricating oil to squeeze the rubber plate 324. At this time, the rubber plate 324 is squeezed outward by the pressure and deformed, thereby separating from each other to open the oil outlet. After that, the lubricating oil can enter the oil outlet hole 325 through the oil outlet and flow to the outer wall of the cable guide roller 2, so as to achieve the purpose of lubricating the outer wall of the cable guide roller 2.
