DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] Currently, deck-operated navigation aid vessels typically have a traction winch at each corner of the operating deck to facilitate the deployment of navigation aids, anchor chains, and sunken rocks. To enable their movement anywhere on the deck, the winch's working rope must be able to swing freely. The rope must pass through a cable guide installed at a certain height to pull the navigation aid, anchor chain, and sunken rock to any position on the deck. However, the existing cable guide has a fixed output direction, making it impossible to freely move navigation aids on the operating deck.

[0030] Based on this, an embodiment of the present disclosure provides a ship's cable guide device, and the installation connection part of the present disclosure is connected to the upper deck as an installation base. The cable guide wheel is partially arranged inside the cable guide drum through the guide wheel connecting part to realize the cable output reversal in the vertical direction, and the cable guide drum is rotated axially through the rotating part so that the cable output is adjusted in the horizontal direction. The present disclosure can solve the problem of the cable output angle, and reasonably and effectively realize the operational requirements of arbitrary movement of navigation equipment on the working deck.

[0031] The following describes the marine cable guide device in detail through specific embodiments:

[0032] Reference Figures 1 to 5 As shown, in the first aspect of the present disclosure, a ship cable guide device is provided, including a cable guide drum 1, a guide wheel assembly 2, a rotating member 3 and a mounting connection portion 4, the mounting connection portion 4 is used to connect to the upper deck 100, the guide wheel assembly 2 includes a guide wheel connector 21 and a cable guide wheel 22, the guide wheel connector 21 is connected to the cable guide drum 1, the cable guide wheel 22 is partially arranged inside the cable guide drum 1 through the guide wheel connector 21, and the wheel surface of the cable guide wheel 22 faces the axis of the cable guide drum 1, wherein the rotating member 3 is connected to the mounting connection portion 4, and the rotating member 3 is used to rotate the cable guide drum 1 along the axial direction.

[0033] The installation connection part 4 of the present disclosure is connected to the upper deck 100 as the installation base, and the connection method can be bolt connection or welding. The present disclosure specifically uses welding to enhance the structural stability of the installation connection 4. Figure 4 As shown, the cable guide wheel 22 of the present invention is partially arranged inside the fairlead 1 through the guide wheel connector 21 to realize the cable output reversal in the vertical direction, and as shown in FIG. Figure 5 As shown, the fairlead 1 is rotated axially by the rotating member 3 so that the cable outflow is adjusted in the horizontal direction. The present disclosure can solve the problem of the cable outflow angle and reasonably and effectively realize the operation requirement of arbitrary movement of navigation equipment on the working deck.

[0034] Specifically, the rotating part of the present invention can be selected, according to the functional requirements and technical characteristics of the ship's cable guide device, the rotating part 3 can be selected from a double-bearing seat rotating mechanism, a turntable slewing bearing or a hydraulically driven rotating module, and an integrated hydraulic motor (such as a cycloidal motor) is used to realize active rotation control. The present invention specifically uses a double-bearing seat rotating mechanism, which is arranged at both ends of the extension direction of the fairlead 1 as a passive rotation basis. When the fairlead 1 is pulled by the cable, it can rotate, so as to facilitate the rapid movement of the navigation equipment without the need to actively rotate the fairlead 1 before it can move. Furthermore, the rotation range of the fairlead 1 of the present invention can be adaptively selected according to the actual use scenario of the ship, and the maximum rotation angle can achieve 360 ​​degrees. In the embodiment of the rotation angle of 360 degrees, the installation connection part 4 needs to give way to the cable so that the installation connection part 4 and other components of the ship will not block the movement of the cable during the rotation of the fairlead 1. In most use scenarios, the rotation angle of the fairlead 1 is less than or equal to 270 degrees. The guide wheel connector 21 of the present disclosure can be a connecting structure such as a connecting rod, a mounting plate or a bracket. The present disclosure specifically uses a mounting plate as the guide wheel connector 21. It should be noted that the cable guide wheel 22 needs to be rotatably connected to the guide wheel connector 21 so that the cable guide wheel 22 can achieve the basic cable derivation function.

[0035] In terms of specific use, the cable of the traction winch 200 passes through the fairlead 1, is arranged on the cable guide wheel 22 partially located inside the fairlead 1, and is led out of the fairlead 1 along the cable guide wheel 22. At this time, the fairlead 1 can limit the position of the cable so that the direction of the rope leading out (vertical direction) is completely determined by the cable guide wheel 22. During the movement of the buoy equipment, the fairlead 1 is swung through the rotating part 3, so that the buoy equipment can be moved arbitrarily on the working deck to meet the operational requirements.

[0036] In some embodiments, the guide wheel connector 21 includes a first support plate 211, a second support plate 212 and a guide wheel shaft 213. There is a guide wheel installation space between the first support plate 211 and the second support plate 212, and the cable guide wheel 22 is arranged in the guide wheel installation space through the guide wheel shaft 213.

[0037] In this embodiment, the symmetrical frame formed by the first support plate 211 and the second support plate 212 of the present disclosure disperses the radial load of the guide wheel shaft 213 to the fairlead 1, significantly improving the load-bearing capacity compared to a single-sided support structure. The cable guide wheel 22 is confined to a preset space, effectively preventing axial movement. Specifically, the first support plate 211 and the second support plate 212 are configured to be detachably connected to the fairlead 1 to facilitate rapid replacement of the cable guide wheel 22 and maintenance of the first support plate 211 and the second support plate 212.

[0038] In some embodiments, the mounting connection portion 4 includes a base 41, a first base elbow plate 42 and a second base elbow plate 43, the rotating member 3 is connected to the base 41, the second base elbow plate 43 is connected to the base 41 through the first base elbow plate 42, and the second base elbow plate 43 is used to connect the upper deck 100.

[0039] In this embodiment, the concentrated load of the rotating part 3 is dispersedly transmitted to the upper deck 100 through the stepped force transmission path of the base 41, the first base bracket 42, and the second base bracket 43, so that the stress peak is reduced to increase the service life. Specifically, the double bracket structure can be set as a torsion-resistant triangular structure, which can withstand a torque deflection of ±15° under the rolling condition of the ship. It should be noted that the first base bracket 42 realizes a flexible transition between the base 41 and the upper deck 100, reducing the welding stress concentration, while the second base bracket 4 expands the connection area with the upper deck 100 and improves the single-point load-bearing capacity. It can be understood that the mounting connection part 4 of the present disclosure does not have to be installed on the upper deck 100 of the ship, and can also be installed in other parts, and can be adaptively selected according to the conditions of use.

[0040] In some embodiments, the second base elbow plate 43 includes a first elbow plate 431 and a second elbow plate 432, the plate surfaces of the first elbow plate 431 and the second elbow plate 432 are arranged opposite to each other, and the first elbow plate 431 and the second elbow plate 432 are vertically arranged on the base 41, and the first base elbow plate 42 is connected to the first elbow plate 431, the second elbow plate 432 and the base 41.

[0041] In this embodiment, the vertically symmetrical structure formed by the first elbow plate 431 and the second elbow plate 432 of the present disclosure greatly improves the shear load distribution and transmission efficiency of the base 41, and through the three-way connection of the first base elbow plate 42, the deck load is converted into axial pressure, thereby reducing the stress concentration factor of the welding area.

[0042] In some embodiments, the first bracket 431 and the second bracket 432 are provided with mounting notches 433, which are connected to the upper deck 100 and are used to adjust the mounting angles of the first bracket 431 and the second bracket 432. Figure 4 As shown, the first bracket 431 and the second bracket 432 are provided with mounting notches 433 , which can better position the upper deck 100 and provide a certain degree of adjustment space according to different inclination angle requirements of the fairlead 1 .

[0043] In some embodiments, the rotating member 3 includes a first bearing seat 31, a second bearing seat 32 and a sleeve 33. The first bearing seat 31 and the second bearing seat 32 are connected to the mounting connection part 4, and the two ends of the guide tube 1 in the extension direction are respectively connected to the first bearing seat 31 and the second bearing seat 32 through the sleeve 33.

[0044] In this embodiment, the first and second bearing seats 31, 32 form a spanning support, reducing the bending moment of the fairlead 1 and effectively avoiding the problem of eccentric wear of the journal caused by single-point support. The synergistic effect of the two bearing seats controls axial runout, maintaining stable rotation even when the ship rolls within ±15°. Furthermore, the first and second bearing seats 31, 32 can utilize a closed oil chamber structure to reduce the corrosion rate in salt spray environments.

[0045] In some embodiments, the apex of the wheel surface of the cable guide wheel 22 located inside the fairlead 1 overlaps with the central axis of the fairlead 1 .

[0046] In this embodiment, the vertex of the cable guide wheel 22 located inside the fairlead 1 overlaps with the central axis of the fairlead 1, so that the portion of the cable guide wheel 22 entering the fairlead 1 occupies half of the internal space of the fairlead 1. When the cable guide wheel 22 occupies 50% of the barrel diameter, the cable contact angle can be controlled within the range of 120°±5°, reducing the peak contact pressure and enhancing dynamic stability. Under the ship rolling condition, this ratio can effectively suppress the risk of cable jumping and reduce the swing amplitude. In addition, half of the internal space of the fairlead 1 is retained to accommodate sudden cable twisting and deformation to avoid jamming.

[0047] In some embodiments, the fairlead 1 is configured as a cylinder, with a guide wheel mounting opening 11 formed on the sidewall of the fairlead 1 along its extension direction, and a cable entry opening 12 provided at the bottom of the fairlead 1. In this embodiment, the cylindrical structure stabilizes the cable contact angle at 120° (±5°), reducing the peak contact stress compared to a rectangular fairlead, and the cylinder has no stress concentration at sharp corners.

[0048] In some embodiments, a jump-stop rod 5 is further included. The jump-stop rod 5 is connected to the guide wheel connector 21 and is used to prevent the cable from escaping from the cable guide wheel 22.

[0049] In this embodiment, the anti-jump rod 5 prevents the rope from jumping out of the pulley during rope operation and causing damage. Specifically, in an embodiment where the guide wheel connector 21 includes a first support plate 211, a second support plate 212, and a guide wheel shaft 213, the anti-jump rod 5 of the present disclosure is disposed within the guide wheel installation space formed by the first support plate 211 and the second support plate 212, and is disposed obliquely above the axis of the cable guide wheel 22, that is, away from the side of the mounting connection portion 4. Its location can prevent the cable from escaping the cable guide wheel 22 and can also limit the rope withdrawal angle according to specific setting parameters.

[0050] In a second aspect of the present disclosure, a navigation aid vessel is provided, comprising the ship cable guide device provided in the first aspect of the present disclosure.
