Description

Technical Field

[0001] This utility model relates to a fixing auxiliary mechanism, and more particularly to a ship cable fixing auxiliary mechanism. Background Technology

[0002] As vital means of transportation and operational platforms on the water, ships operate in complex and harsh environments. During navigation or operations, ships are continuously subjected to vibrations and shocks caused by various factors, including main engine operation, propeller work, and wave impact. These vibrations are broadband and multidirectional, posing a severe challenge to various equipment on board, especially the cable system.

[0003] Cables are the nerves and blood vessels of a ship, responsible for transmitting electricity and signals. Their safety and reliability are directly related to the ship's normal operation and the safety of lives. Currently, the traditional method of securing cables on ships mainly includes nylon cable ties, which bind cable bundles to supports. This method is low-cost and quick to install, but the cable ties may exert excessive tension on the cables after tightening, and the sharp edges of the ties can cause "fretting abrasion" under vibration, posing a risk of wear. In addition, nylon materials are prone to aging and embrittlement in marine environments.

[0004] This also includes rigid cable supports, which place cables in slots within metal or non-metal supports and then seal them with covers. While these provide support, they lack effective vibration damping and anti-friction designs, and the cables will still collide and rub against the channel walls due to vibration within the channel.

[0005] Through in-depth analysis and practical testing of existing technologies, the inventors discovered that these traditional cable fixing methods suffer from the following common defects: poor versatility and adaptability. Ships carry a wide variety of cable specifications, ranging from thin signal lines to thick power cables, with significant size differences. This necessitates the storage of a large number of different specifications of fixing components on board, increasing the complexity and cost of procurement, management, and installation.

[0006] In summary, there is an urgent need in this field for a new cable fixing solution that can flexibly adapt to various cable specifications and has the advantages of easy installation and maintenance. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this utility model provides a ship cable fixing auxiliary mechanism.

[0008] To solve the above technical problems, the technical solution adopted by this utility model is: a ship cable fixing auxiliary mechanism, comprising: The main body is a C-shaped sheet structure that wraps around the cable, and the C-shaped sheet structure has an opening that slopes upwards to allow the cable to enter and exit. Two anti-friction roller assemblies are installed on the sides of the opening at both ends of the main body. The anti-friction roller assembly has rollers that can be adjusted to move radially along the C-shaped main body. The wheel surface of the rollers is used to contact the outer periphery of the cable with the cable surface. The sliding base includes a slider and a slide rail. The slider is fixedly connected to the bottom outer side of the main body, and the slider is slidably mounted on the slide rail fixed to the hull.

[0009] Furthermore, the friction-reducing roller assembly includes a fixed plate and a fixed post connected to the C-shaped body. The fixed plate and the fixed post are located on opposite sides of the C-shaped body. An adjusting bolt is screwed onto the fixed plate. The adjusting bolt is arranged radially along the C-shaped body and rotates through the L-shaped transmission plate. The roller is rotatably connected to the end of the L-shaped transmission plate. A groove is provided on the L-shaped transmission plate. The fixed post slides within the groove. The adjusting bolt moves on the fixed plate to adjust the position of the L-shaped transmission plate on the C-shaped body, allowing the L-shaped transmission plate roller to move within the encircling range of the body.

[0010] Furthermore, the fixed plate is perpendicular to the main body; the first plate of the L-shaped transmission plate is parallel to the fixed plate, and a through hole is provided on the first plate for the screw of the adjusting bolt to pass through. A compression spring is provided between the through hole of the first plate and the nut of the bolt; a sliding groove is provided on the second plate of the L-shaped transmission plate, and the direction of the sliding groove is parallel to the moving direction of the adjusting bolt.

[0011] Furthermore, the slider is simultaneously matched on two parallel slides, and the slider is slidably set on the slides along the axial direction of the cable.

[0012] Furthermore, a barrier block is provided between the two parallel slides to limit the sliding range of the slider.

[0013] This invention utilizes a radial stepless adjustment mechanism driven by adjusting bolts, allowing a single device to accommodate cables with a wide diameter range, eliminating the need for multiple clamps for different cables and thus solving the problem of poor versatility and adaptability. The unique axial sliding base design enables fine-tuning of the final position of the fixing point after cable laying, avoiding the hassle of precise measurement and positioning required in traditional methods, greatly improving installation efficiency and flexibility, and solving the problem of inconvenient installation and adjustment. The anti-friction roller design is a fundamental solution, changing the friction at the fixing point from sliding to rolling, significantly reducing wear and addressing insufficient wear resistance. Integrating radial fixing and axial adjustment functions into a compact mechanism, the ingenious structure and powerful functionality make it easy to deploy in space-constrained environments on ships, resulting in high structural integration.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment provides a ship cable fixing mechanism, including a main body, a contact part, and a base part, specifically, as follows: Figs. 1-3 As shown; The main body 1 of the main body has a C-shaped sheet structure. This design can wrap around the cable. Its opening is slanted upward, which makes it easy for the cable to enter and exit from the side. The main body serves as the main body for the installation of the entire mechanism. The contact section mainly refers to the anti-friction roller assembly, which performs the core functions of adjusting and clamping the cable and adapting to cables of different specifications. Specifically, it includes two anti-friction roller assemblies on the side of the opening of the main body 1. Each assembly includes key components such as a fixing plate 21, which is vertically connected to one side of the main body 1 and has threaded holes; a fixing post 22, which is set on the other side of the main body 1, that is, the fixing plate 21 and the fixing post 22 are located on both sides of the C-shaped sheet structure; and an L-shaped transmission plate 23, which is composed of a first plate and a second plate that are perpendicular to each other. The first plate is parallel to the fixed plate 21 and has a through hole. The second plate has a strip-shaped groove 231. The extension direction of the groove 231 is parallel to the radial direction of the cable, that is, the clamping direction. An adjusting bolt 24 is threaded into the threaded hole of the fixed plate 21. The screw part is screwed into the threaded hole of the fixed plate 21. The screw part near the nut passes through the through hole on the first plate of the L-shaped transmission plate 23. A compression spring 25 is sleeved between the nut of the adjusting bolt 24 and the first plate. A friction-reducing roller 26 is rotatably installed at the end of the second plate of the L-shaped transmission plate 23.

[0020] After the cable enters through the opening of the C-shaped sheet structure, the anti-friction roller assembly clamps the cable. Using a tool, the adjusting bolt 24 is tightened. Rotating the adjusting bolt 24 clockwise pushes it towards the cable. The nut of the adjusting bolt 24 drives the entire L-shaped transmission plate 23 to move closer to the cable. Due to the sliding fit between the groove 231 on the L-shaped transmission plate 23 and the fixed column 22 on the main body 1, the L-shaped transmission plate 23 can only move in a straight line without deflection. Ultimately, this causes the anti-friction roller 26 at its end to press against the cable surface. Simultaneously, a compression spring 25 is fitted between the nut of the adjusting bolt 24 and the first plate to provide elastic compensation. When the two applied forces are adjusted, a stable clamping effect on the cable surface can be achieved. It should be understood that the contact surface with the cable should avoid being blade-shaped; for example, chamfering can be done on the C-shaped sheet structure or the anti-friction roller 26. During this process, the anti-friction roller 26 also assists in the movement of the cable through its rolling action during entry and exit.

[0021] The base portion includes slide rails 31 and sliders 32. At least two parallel slide rails 31 are fixedly mounted to the hull structure by bolts or other means. The extension direction of the slide rails 31 is parallel to the axial direction of the cable. The sliders 32 are fixedly connected to the bottom outer side of the main body 1. The lower part of the sliders 32 is provided with grooves or protrusions that match the cross-sectional shape of the slide rails 31, so that the sliders 32 can be smoothly engaged on the slide rails 31 and slide along them.

[0022] When laying cables, multiple mechanisms of this invention can be pre-installed on the slide rails 31, but do not need to be locked immediately. When the final fixed position needs to be determined, the mechanism needs to be pushed, and the entire mechanism can slide on the slide rails 31 via the slider 32, easily adjusting its position along the cable length. After the position is determined, note that the relative position of the slider 32 and the slide rails 31 can be fixed by additional set screws or by designing a self-locking structure. In addition, a blocking block 33 can be set between two parallel slide rails 31 to limit the sliding range of the slider 32, preventing it from coming off the end of the slide rail or moving in an unexpected range.

[0023] How does this utility model solve the problems in the background art? By adjusting the radial stepless adjustment mechanism driven by the bolt, one model of this device can adapt to cables with a large diameter range, eliminating the need to prepare multiple clamps for different cables, thus solving the problem of poor versatility and adaptability.

[0024] The unique axial sliding base design allows the final position of the fixing point to be finely adjusted after the cable laying is completed, avoiding the trouble of precise measurement and positioning required by traditional methods, greatly improving installation efficiency and flexibility, and solving the problem of inconvenient installation and adjustment.

[0025] The design of friction-reducing rollers is a fundamental solution, changing the frictional nature at fixed points from sliding to rolling, greatly reducing wear and solving the problem of insufficient wear resistance.

[0026] The radial fixing and axial adjustment functions are integrated into a compact mechanism, which is ingenious, powerful and easy to deploy in the space-constrained environment of ships, resulting in a high degree of structural integration.

[0027] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
