[0023] like Figure 1-Figure 4As shown, this embodiment adopts the following technical solution: it comprises a mounting seat 1 and a fairlead hole body 2, the fairlead hole body 2 is fixedly arranged on the mounting seat 1, and inclined reinforcing rib plates 17 are fixedly arranged on the front and rear sides of the left and right side walls of the fairlead hole body 2, and the reinforcing rib plates 17 are fixedly connected to the mounting seat 1, and the reinforcing rib plates 17 can improve the strength of the connection structure between the fairlead hole body 2 and the mounting seat 1, so that the force bearing performance of the fairlead hole can be enhanced;

[0024] It also contains:

[0025] A cable hole cover 3, wherein the cable hole cover 3 is two in number and is respectively set on the front and rear sides of the inner side of the main body 2 of the cable guide hole. Two connecting rods 4 are fixedly set on the side wall of the cable hole cover 3. Several plugging rods 15 are fixedly set on the side wall of the front cable hole cover 3 with equal fillet distribution. The plugging rods 15 are movably inserted in the side wall of the rear cable hole cover 3. The connection of the two cable hole covers 3 can be achieved through the plugging rods 15, so that the installation of the cable hole cover 3 on the main body 2 of the cable guide hole is more stable. Several limit blocks 16 are fixedly set on the front and rear side walls of the main body 2 of the cable guide hole. The limit blocks 16 are movably set in the grooves provided on the cable hole cover 3. The limit blocks 16 can realize the installation limit of the cable hole cover 3 on the main body 2 of the cable guide hole;

[0026] Reinforcement frames 5, wherein the reinforcement frames 5 are two and are respectively fixedly arranged on the left and right sides of the main body of the fairlead hole 2, and the connecting rod 4 passes through the main body of the fairlead hole 2 and is movably inserted into the reinforcement frames 5;

[0027] The horizontal plates 6 are four in number and are respectively movably disposed on the upper and lower sides of the two reinforcement frames 5. A plurality of limit rods 7 are fixedly disposed on the horizontal plates 6. The limit rods 7 are movably inserted in the reinforcement frames 5, and one end of the limit rods 7 is movably inserted on the connecting rod 4.

[0028] Spring 8, there are two springs 8, which are movably arranged in two reinforcement frames 5 respectively, and the ends of the spring 8 are fixedly connected to the cross plate 6. A rotating frame 9 is screwed on the side wall of the reinforcement frame 5 through an axis and a bearing. Guide frames 10 are fixedly arranged on the upper and lower sides of the rotating frame 9. A guide rod 18 is fixedly arranged on the side wall of the cross plate 6, and the guide rod 18 is movably arranged on the guide frame 10.

[0029] Embodiment 2:

[0030] like Figure 2 and Figure 4 As shown, this embodiment is improved on the basis of the first embodiment, a threaded rod 11 is inserted on the rotating frame 9 through a bearing rotation connection, a movable plate 12 is sleeved on the threaded rod 11 through a threaded rotation connection, and two positioning rods 13 are fixedly provided on the movable plate 12. After the positioning rod 13 passes through the rotating frame 9, it is movably abutted in a positioning groove 14 opened on the side wall of the reinforcement frame 5.

[0031] When the utility model is used, the guide cable can be inserted into the two cable hole covers 3. The cable hole covers 3 protect the main body 2 of the cable hole, so as to avoid the friction between the guide cable and the main body 2 of the cable hole, thereby preventing the main body 2 of the cable hole from being worn and damaged. When the cable hole cover 3 needs to be replaced due to severe wear, the threaded rod 11 can be rotated so that the movable plate 12 drives the positioning rod 13 to move toward the inside of the rotating frame 9. At this time, one end of the positioning rod 13 is disengaged from the positioning groove 14 on the reinforcement frame 5. Then the rotating frame 9 can be rotated to make the rotating frame 9 tilted, and with the cooperation of the guide frame 10, the guide rod 18 drives the cross plate 6 to move away from the reinforcement frame 5. At this time, the spring 8 is in a stretched state, and the cross plate 6 drives the limit rod 7 to move and disengage from the connecting rod 4. Then the cable hole covers 3 on the front and rear sides can be moved in opposite directions. The cable hole cover 3 is disassembled from the cable guide hole main body 2, and then the intact cable hole cover 3 is installed in the cable guide hole main body 2. The cable hole cover 3 drives the connecting rod 4 to be inserted into the reinforcement frame 5, and then the rotating frame 9 is loosened. At this time, the spring 8 is reset and shortened, and the spring 8 drives the cross plate 6 to move in the direction of the reinforcement frame 5. The cross plate 6 makes the rotating frame 9 rotate to the vertical state again through the guide rod 18 and the guide frame 10. At the same time, the cross plate 6 drives the limiting rod 7 to move, so that the limiting rod 7 is inserted into the connecting rod 4. While limiting the connecting rod 4, it can also achieve the limiting of the cable hole cover 3 after installation on the cable guide hole main body 2. Thereafter, the threaded rod 11 is rotated in the opposite direction, so that the movable plate 12 drives the positioning rod 13 to move away from the rotating frame 9. At this time, one end of the positioning rod 13 can be inserted into the positioning groove 14 on the reinforcement frame 5 to limit the rotating frame 9.

[0032] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0033] 1. The cable hole cover 3 can protect the cable hole to prevent the cable from being directly rubbed on the cable hole and causing wear of the cable hole. The cable hole cover 3 can also be installed and disassembled by using the cooperation of the connecting rod 4, the reinforcement frame 5, the cross plate 6, the limit rod 7, the spring 8, the rotating frame 9 and the guide frame 10, so as to facilitate the replacement of the damaged cable hole cover 3.

[0034] 2. The inclined reinforcing rib plate 17 can effectively improve the strength of the connection structure between the main body 2 of the cable guide hole and the mounting seat 1, so that the load-bearing performance of the cable guide hole can be enhanced.

[0035] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
