Technical Field

[0001] This utility model belongs to the technical field of ship cable guides, specifically relating to a marine roller cable guide. Background Technology

[0002] Mooring equipment for ships includes bollards, roller guides, guide holes, anchor winches (or winches), and cables. Among these, the roller guides and guide holes are mounted on the bulwark. The roller guide's rollers rotate around a central axis. During cable deployment and retraction, the rollers rotate, converting the linear friction of the cable within the guide hole into rolling friction, thus reducing cable wear. However, in existing ISO guide standards, the roller guide's rollers and shaft rotate synchronously, requiring the rollers and base to be installed as a single unit, which presents significant installation challenges. Utility Model Content

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide a marine roller guide.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0038] Example 1 (Four-roller cable guide)

[0039] Figure 1 The figure shows a perspective view of the marine four-roller guide provided in this embodiment. As can be seen from the figure, the four-roller guide includes a frame 100 and roller modules 300 that are guided and installed on the frame 100 by a guide mechanism 200.

[0040] Continue to refer to Figure 2 As shown, the frame 100 includes vertical plates 101 on the left and right sides and horizontal plates 102 on the top and bottom sides. The horizontal plates 102 are vertically welded and fixed to the vertical plates 101, and an installation space for installing the roller module 300 is formed between the vertical plates 101 and the horizontal plates 102.

[0041] In one executable embodiment of this example, the upper horizontal plate 102 is fixed to the top of the vertical plate 101, and the lower horizontal plate 102 is fixed between the left and right vertical plates 101, so that a transition space is formed at the bottom of the frame 100. Specifically, by utilizing this transition space, the overall frame 100 can be flexibly adapted to installation at different locations on the bulwark (such as upright installation of the frame 100, inclined installation of the frame 100, etc.). This embodiment demonstrates upright installation.

[0042] In another executable embodiment of this example, a bent reinforcing inclined plate 105 is formed extending from the front side of the vertical plate 101, thereby improving the structural strength of the frame 100 and increasing the contact area between the vertical plate 101 and the deck when the frame 100 is welded and fixed on the deck, thus ensuring welding stability.

[0043] Continue to refer to Figure 2 As shown, the guiding mechanism 200 includes a guiding through hole 203, and the guiding through holes 203 on the left and right vertical plates 101 cooperate to form a horizontal guiding member 201, and the guiding through holes 203 on at least the upper horizontal plate 102 cooperate to form a vertical guiding member 202.

[0044] In an executable embodiment of this first embodiment, at least the vertical guide member 202 further includes a guide positioning ring 204. In the figure, the guide positioning ring 204 is welded and fixed to the lower horizontal plate 102, and the center of the guide positioning ring 204 is on the same straight line as the center of the guide through hole 203 on the upper horizontal plate 102, thereby accurately determining the central axis guided by the vertical guide member 202.

[0045] Continue to refer to Figure 1 As shown, the roller module 300 includes a horizontal roller group and a vertical roller group. In the four-roller cable guide of this embodiment, the horizontal roller group includes two parallel horizontal rollers 303, and the vertical roller group includes two parallel vertical rollers 304, and a cable guide channel for passing through the cable is formed between the horizontal rollers 303 and the vertical rollers 304.

[0046] In the executable implementation of this first embodiment, combined with Figure 9 and Figure 11 As shown, the horizontal roller 303 and the vertical roller 304 are collectively referred to as rollers 301, and a central shaft 302 is detachably mounted at the center of each roller 301.

[0047] In summary, when installing the four-roller cable guide of this embodiment, the fixed frame 100 can be welded first, and then the roller module 300 can be installed by using the guiding mechanism 200 to guide it.

[0048] Vertical roller assembly installation: Place the vertical roller 304 into the installation space within the frame 100 (while simultaneously providing washers 308 at least at the ends of the vertical roller 304 to reduce wear between the vertical roller 304 and the frame 100), and then... Figure 12 As shown, at least an annular groove 309 is provided at the bottom end of the vertical roller 304. Therefore, the vertical roller 304 can be positioned by engaging the annular groove 309 with the guide positioning ring 204, ensuring that the center of the guide positioning ring 204, the center of the vertical roller 304, and the center of the guide through hole 203 on the upper horizontal plate 102 are all on the same straight line. The central shaft 302 is inserted sequentially from the top of the upper horizontal plate 102 into the guide through hole 203, the vertical roller 304, and the guide positioning ring 204, completing the guided assembly of the vertical roller 304 and the central shaft 302. In addition, combined with Figure 10As shown, a stop groove 305 is provided at the end of the central shaft 303. A stop plate 307, in which a bolt 306 is installed, can be engaged in the stop groove 305. Thus, after the central shaft 302 is guided and installed, according to... Figure 1 As shown, the stop plate 307 is snapped into the stop groove 305, and then the frame 100 and the stop plate 307 are fixed with bolts 306 to realize the installation of the whole vertical roller assembly.

[0049] Horizontal roller assembly installation: Place the horizontal roller 303 into the installation space within the frame 100 (with washers 308 at both ends of the horizontal roller 303 to reduce wear between the horizontal roller 303 and the frame 100), ensuring that the center of the horizontal roller 303 and the center of the guide holes 203 on the left and right vertical plates 101 are on the same straight line. Insert the central shaft 302 into the guide holes 203, the horizontal roller 303, and the guide holes 203 sequentially from the left or right side (selected flexibly according to the actual installation position), completing the guided assembly of the horizontal roller 303 and the central shaft 302. Additionally, combined with... Figure 10 As shown, a stop groove 305 is provided at the end of the central shaft 303. A stop plate 307, in which a bolt 306 is installed, can be engaged in the stop groove 305. Thus, after the central shaft 302 is guided and installed, according to... Figure 1 As shown, the stop plate 307 is snapped into the stop groove 305, and then the frame 100 and the stop plate 307 are fixed with bolts 306 to realize the installation of the whole transverse roller assembly.
