[0003] In the prior art, Chinese patent CN201710934561.2 discloses an auxiliary tooling for laying marine cables, used to assist in laying cables on cable trays during ship construction. It includes a hanger and rollers; the hanger is suspended on two circular tubes of the cable tray; the rollers are fixed to the hanger and can rotate along its transverse central axis. This invention addresses the technical problem in the prior art where laying cables on cable trays involves high friction, leading to time-consuming, labor-intensive work and easy scratching of the cable surface. It provides an auxiliary tooling and method that saves time and labor and reduces the degree of scratching on the cable surface during cable laying on cable trays.

[0004] Although the aforementioned patent can reduce the resistance when laying cables on cable trays by rotating the rollers on the auxiliary tooling, there is a lack of restraint on both sides of the rollers during cable transportation. The cables are prone to detaching from the sides of the rollers during laying, causing the rollers to lose their function and affecting the laying efficiency of the cables.

[0005] Therefore, this utility model proposes a marine cable laying guide device to solve the above problems. Summary of the Invention

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a marine cable laying guide device to solve the problems in the prior art where the rollers lack restraint on both sides, the cable easily detaches from the sides of the rollers during laying, and the rollers become ineffective, thus affecting the laying efficiency of the cable.

[0007] The purpose of this utility model is achieved as follows:

[0008] A marine cable laying guide device includes a base with side plates installed at both ends. Multiple support assemblies are installed on the top of the base. Each support assembly includes two end seats fixedly installed on the top of the base, with a support roller rotatably connected between the two end seats. Multiple side support assemblies are installed on both ends of the support rollers on the top of the base. Each side support assembly includes a second bracket, with a side roller rotatably installed on the outer end of the second bracket. An installation groove is formed on the base below the second bracket, with a sliding rod fixedly installed on the inner side of the installation groove. A second slider is fixedly installed on the bottom end of the second bracket.

[0009] As a preferred technical solution of this application, the second slider is provided with a through hole.

[0010] As a preferred technical solution of this application, the second bracket is L-shaped, and a diagonal rod is fixedly installed on the inner side of the second bracket.

[0011] As a preferred technical solution of this application, a limiting mechanism is fixedly installed at both ends of the top of the base.

[0012] As a preferred technical solution of this application, the limiting mechanism includes a stand fixedly connected to the base by bolts, a threaded rod rotatably installed inside the stand, a first slider threadedly connected to the threaded rod, a first bracket fixedly installed on the side of the first slider, and a pressure roller rotatably installed on the inner side of the first bracket.

[0013] As a preferred technical solution of this application, the top of the support frame is provided with a rotating handle connected to the threaded rod.

[0014] As a preferred technical solution of this application, the side roller is located in the gap between the two support rollers.

[0015] Compared with the prior art, this utility model provides a marine cable laying guide device, which has the following beneficial effects:

[0016] (1) By setting the side support component, when the cable is laid by the support roller, the side rollers located on both sides of the top of the base limit the two sides of the cable, prevent the cable from falling off during laying, improve the laying efficiency of the cable, and solve the problem that the two sides of the roller lack restriction in the prior art, and the cable is easy to fall off the two sides of the roller during laying, which causes the roller to lose its function and affects the laying efficiency of the cable.

[0024] To better understand the technical solution of this utility model, a detailed description will be provided below in conjunction with relevant illustrations. It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0025] See Figure 1-4 , Figure 1 A schematic diagram of a marine cable laying guide device according to Embodiment 1 is shown. As shown in the figure, the marine cable laying guide device according to Embodiment 1 includes a base 1, with side plates 2 installed at both ends of the base 1. During use, it is convenient to be bolted or welded to the surface of the ship's hull frame. Multiple support components are installed on the top of the base 1 to support the cable and facilitate laying. The support components include two end seats 13 fixedly installed on the top of the base 1, and a support roller 8 is rotatably connected between the two end seats 13. By rotating the support roller 8, static friction can be converted into dynamic friction during cable laying, effectively reducing friction on the surface of the cable during movement and effectively reducing damage.

[0026] Reference Figure 1 and Figure 4 The top of the base 1 is equipped with multiple side support components at both ends of the support roller 8. The side support components limit the cable located on the support roller 8 to prevent the cable from falling off during the operation, making it more convenient and stable to use.

[0027] The side support assembly includes a second bracket 6, which is L-shaped, and an inclined rod is fixedly installed on the inner side of the second bracket 6 to improve the stability of the second bracket 6 during use. A side roller 7 is rotatably installed on the outer end of the second bracket 6. The side roller 7 is located in the gap between two support rollers 8. When laying cables, the side rollers 7 on both sides can limit the cable and effectively prevent the cable from falling off, making it more stable during use.

[0028] The base 1 has an installation groove 10 located below the second bracket 6. A slide rod 11 is fixedly installed on the inner side of the installation groove 10. A second slider 15 is fixedly installed at the bottom end of the second bracket 6. The second slider 15 has a through hole. During use, the second slider 15 can slide in the installation groove 10 to facilitate the adjustment of the distance between the two opposite side rollers 7. During use, the side rollers 7 can limit the cable and maintain the stability of cable transportation. In addition, at corners, by adjusting the position of the side rollers 7, the bending of the cable at the corner can be made more natural and stable, improving the efficiency and safety of cable laying.

[0029] Reference Figure 1 and Figure 3 Limiting mechanisms are fixedly installed at both ends of the top of the base 1. The limiting mechanisms are respectively installed on the base 1. During use, the cable located on the support roller 8 is limited by two pressure rollers 4. This is to prevent the cable from jumping due to movement during the cable sliding process, which would affect the cable laying efficiency and easily cause wear on the cable sheath.

[0030] The limiting mechanism includes a stand 3 fixedly connected to the base 1 by bolts. A threaded rod 12 is rotatably installed inside the stand 3. A rotating handle 9 connected to the threaded rod 12 is provided on the top of the stand 3. A first slider 14 is threadedly connected to the threaded rod 12. A first bracket 5 is fixedly installed on the side of the first slider 14. A pressure roller 4 is rotatably installed on the inner side of the first bracket 5. In use, rotating the rotating handle 9 can drive the threaded rod 12 to rotate. The rotating threaded rod 12 drives the first slider 14 to move up and down. When laying cables, the pressure roller 4, after descending, limits the top two ends of the base 1, maintaining the stability of the cable during transportation and reducing friction damage.

[0031] Working principle:

[0032] This utility model provides a marine cable laying guide device. In use, the cable is passed under the pressure roller 4 at one end of the top of the base 1, and then supported by multiple support rollers 8. Finally, the cable passes under the pressure roller 4 at the other end of the top of the base 1. When the cable is pulled, the support rollers 8 support the cable and the distance between the opposite side rollers 7 is adjusted to clamp the cable. The pressure rollers 4 at both ends limit the cable at both ends of the top of the base 1 to keep the cable stable during laying.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
