[0041] Along the axial direction of the guiding shaft 21, the guiding portion 222 is located in the middle of the connecting portion 221, and the thickness of the connecting portion 221 is greater than the thickness of the guiding portion 222, so as to form a clamping groove 2210 between the connecting portion 221 and the guiding portion 222. The guiding assembly 2 further comprises a fastener 20, the fastener 20 is partially located in the clamping groove 2210, and the fastener 20 is detachably inserted in the connecting portion 221 and the guiding shaft 21.

[0042] In the above implementation manner, the guiding block 22 is provided as the connecting portion 221 and the guiding portion 222, so that the fastener 20 can be conveniently accommodated in the clamping groove 2210 formed between the connecting portion 221 and the guiding shaft 21, and the detachable connection between the guiding block 22 and the guiding shaft 21 is realized through the fastener 20.

[0043] In this embodiment, the guide block 22 is an integrally cast structure, which can improve the machining efficiency of the guide block 22.

[0044] Exemplarily, the rope groove 220 is a V-shaped groove, which can accommodate various ropes with different diameters through the gradually changing width between the two opposite side walls of the V-shaped groove (the side walls along the axial direction of the guide shaft 21).

[0045] Optionally, the connecting portion 221 is provided with a plurality of first threaded holes in the circumferential direction thereof, and the first threaded holes extend in the radial direction of the connecting portion 221. Correspondingly, the outer circumferential wall of the guide shaft 21 is provided with a plurality of second threaded holes arranged in the circumferential direction and corresponding to the first threaded holes one by one, and the fastener 20 is inserted into the corresponding first threaded hole and second threaded hole to achieve the detachable connection between the guide shaft 21 and the guide block 22.

[0046] The fastener 20 includes a bolt, a gasket, a nut, and the like.

[0047] Optionally, the guide shaft 21 has a liquid supply channel 211 inside, and the inlet of the liquid supply channel 211 is used to supply lubricating liquid to the inside of the guide shaft 21. The guide block 22 has a flow-through channel 223 inside, and the inlet of the flow-through channel 223 is in communication with the outlet of the liquid supply channel 211, and the outlet of the flow-through channel 223 is in communication with the rope groove 220.

[0048] In the above implementation, the liquid supply channel 211 is arranged inside the guide shaft 21, and the external lubricating liquid (such as lubricating oil or cleaning agent, etc.) can be introduced into the inside of the guide shaft 21 through the liquid supply channel 211.

[0049] And the flow-through channel 223 is arranged inside the guide block 22, and the lubricating liquid flowing into the liquid supply channel 211 can be introduced into the flow-through channel 223 and flow to the rope groove 220 through the flow-through channel 223 to lubricate or clean the rope in the rope groove 220.

[0050] Exemplarily, the liquid supply channel 211 includes an axial flow-through section 2111 and a plurality of radial flow-through sections 2112, the axial flow-through section 2111 extends along the axial direction of the guide shaft 21, and the radial flow-through sections 2112 are arranged along the radial direction of the guide shaft 21. One end of the axial flow-through section 2111 is connected to one end of each radial flow-through section 2112. The plurality of radial flow-through sections 2112 are arranged one by one corresponding to the plurality of guide blocks 22, and the other end of the radial flow-through section 2112 is in communication with the flow-through channel 223 of the corresponding guide block 22. In this way, the liquid supply channel 211 can be quickly machined.

[0051] Exemplarily, the flow channel 223 extends along the radial direction of the guide shaft 21. Each radial flow section 2112 is in line with the flow channel 223 of the corresponding guide block 22. In this way, the lubricating oil can flow from the radial flow section 2112 to the flow channel 223 quickly.

[0052] In the embodiment, if the cable is a steel rope, the lubricating oil can be butter. If the cable is made of nylon or other materials, the lubricating oil can be a cleaning agent.

[0053] Referring again to Figure 3 and Figure 4 Optionally, the guide assembly 2 further comprises a plurality of guide balls 23 and a plurality of elastic members 24, the plurality of guide balls 23 and the plurality of elastic members 24 are arranged one by one in correspondence, and the plurality of guide balls 23 and the plurality of guide blocks 22 are arranged one by one in correspondence. The guide ball 23 is connected with one end of the corresponding elastic member 24, the other end of the elastic member 24 is connected in the flow channel 223 of the guide block 22 corresponding to the guide ball 23, the elastic member 24 can stretch and contract along its own axis, and at least part of the guide ball 23 is located in the flow channel 223 of the corresponding guide block 22.

[0054] In the above implementation, the guide ball 23 and the elastic member 24 are connected in the inside of each guide block 22 in correspondence. When the cable is guided, the cable is located in the rope groove 220 and presses the guide ball 23, the guide ball 23 is pressed by the cable to press the elastic member 24, in the process of pressing, the lubricating liquid in the flow channel 223 flows out to contact the cable to lubricate the cable. When the cable is not guided, the guide ball 23 can properly hinder the loss of lubricating liquid.

[0055] The elastic member 24 mentioned above is a compression spring. In this way, the elastic member 24 can stretch and contract along its own axis. In addition, the guide ball 23 is a steel ball, which can reduce the friction between the guide ball 23 and the cable.

[0056] Optionally, the guide assembly 2 further comprises a plurality of sealing ring covers 25, the plurality of sealing ring covers 25 and the plurality of guide blocks 22 are arranged one by one in correspondence, and the sealing ring cover 25 is located at the outlet of the flow channel 223 of the corresponding guide block 22 and is connected with the guide block 22. The guide ball 23 is located at the opening of the sealing ring cover 25 and abuts against the inner wall of the sealing ring cover 25 when not pressed by the cable.

[0057] In the above implementation, the sealing ring cover 25 is used to seal the guide ball 23, so that the guide ball 23 and the elastic member 24 can seal the outlet of the flow channel 223 in the natural state (when not pressed by the cable), avoiding the lubricating liquid in the flow channel 223 from flowing out. When guiding the cable, the lubricating liquid can flow into the rope groove 220 along the gap between the guide ball 23 and the sealing ring cover 25.

[0058] In this embodiment, in order to facilitate the manufacture of the sealing ring cover 25, the sealing ring cover 25 is connected in the flow passage 223 by means of metal glue. When installing, first, one end of the elastic member 24 is placed in the flow passage 223 and welded with the inner wall of the guide block 22, then the guide ball 23 is placed in the flow passage 223 and welded with the other end of the elastic member 24, then a rubber plate containing a T-shaped structure (composed of a vertical rod and a circular plate) is placed at the opening of the flow passage 223, and the metal glue is solidified above the circular plate of the rubber plate and around the vertical rod of the rubber plate, so that the metal glue forms a hole-shaped sealing ring cover 25 with a central hole. After the metal glue cools and solidifies, the rubber plate is deformed and pulled out along the central hole of the metal glue. In this way, the sealing ring cover 25 can be connected in the flow passage 223.

[0059] Of course, the sealing ring cover 25 can also be of other structures, such as a steel ring cover plate, etc., which can be connected in the flow passage 223 by welding.

[0065] Exemplarily, the support plate 111, the plurality of support columns 113 and the connecting plate 114 are connected into one body by welding.

[0066] In order to facilitate the installation of the rotating shaft 12, the fixing frame 11 further comprises two bearing seats 115 and two bearing bushes 116.

The connecting ends of the rotating shaft 12 are respectively inserted into the two bearing bushes 116. In this way, the rotating shaft 12 can be rotatably installed on the support plate 111, and at the same time, the rotating friction of the rotating shaft 12 can be reduced.

[0067] Exemplarily, the bearing seat 115 is connected on the support plate 111 by welding.

[0068] Optionally, the cable guiding device further comprises a clutch 4 connected with the rotating shaft 12 to control the rotation of the rotating shaft 12.

[0069] In the above implementation manner, the clutch 4 is used to control the rotation of the rotating shaft 12 to adjust the spatial position of the guide block 22, so as to facilitate the layout of the cable.

[0070] In this embodiment, the specific structure of the clutch 4 can refer to the text disclosed in CN107387592A, which will not be described here.

The positions opposite to the rotating shaft 12 between the first side plate 131, the second side plate 132, the first connecting plate 133 and the second connecting plate 134 have openings for the cable to pass through.

[0072] In the above implementation, the bogie 13 is arranged in the above structure, the first side plate 131 and the second side plate 132 are connected with the two ends of the rotating shaft 12 respectively, and the bogie 13 forms a cavity with an opening, so that the guide block 22 is arranged inside the bogie 13. In addition, the opening on the bogie 13 can facilitate the cable to pass out after being guided by the guide block 22.

[0073] For example, in order to facilitate the viewing of the state of the cable on the guide block 22 and reduce the weight of the bogie 13, a plurality of fan-shaped holes are arranged on the first connecting plate 133 and the second connecting plate 134 and close to the opening on the bogie 13.

[0082] In the above implementation, two rollers 31 are arranged on one side of the axial line of the rotating shaft 12, so that the gap formed between the two rollers 31 can be used as another rope entering direction.

[0083] For example, when a cable recovered from seawater, the cable can be passed through the gap formed between the two rollers 31, and then passed through the opening 1200 on the rotating shaft 12 and the rope passing cavity 120, and guided by the guide block 22, so that it can be recovered. That is, the cable first passes through the gap between the two rollers 31, and then enters the rotating shaft 12 through the opening 1200, and then is wound in the rope groove 220 and guided by the guide block 22 and then extends out of the opening of the bogie 13.

[0084] That is, the above arrangement can increase one rope entering mode, so that different rope entering modes can be selected according to the different use states of the cable. For example, a clean cable or a cable used in the cabin can pass through the inside of the rotating shaft 12. A cable used in water operation or a cable with marine organisms attached thereto can pass through the gap between the rollers 31 (because it passes through the gap, the organisms attached to the cable can be filtered out indirectly).

[0085] In addition, in order to facilitate the arrangement of the cable, the opening 1200 is located in the middle of the axial direction of the rotating shaft 12, and the projection of the opening 1200 on the roller 31 is located on the side of the roller 31 toward the axial line of the first connecting plate 133 along the direction perpendicular to the axial direction of the rotating shaft 12.

[0086] In this embodiment, in order to adjust the gap between the two rollers 31, a plurality of connecting holes are arranged on the first side plate 131 and the second side plate 132, and the plurality of connecting holes on the first side plate 131 and the plurality of connecting holes on the second side plate 132 are arranged along the axis perpendicular to the rollers 31.

[0087] In this way, the two rollers 31 can be connected to the first side plate 131 and the second side plate 132 respectively according to different specifications (outer diameter) of the cable, so that the gap between the two rollers 31 can just allow the cable to pass through.

[0088] Exemplarily, the rollers 31 are connected to the first side plate 131 and the second side plate 132 by bolts or other fasteners.

[0089] Figure 8 For Figure 1 a structural schematic view of the transfer shaft, Figure 9 for Figure 8 a sectional view along the direction B-B, in combination with Figure 8 and 9 Exemplarily, the transfer shaft 12 includes a first plug-in section 121, a second plug-in section 122, and an intermediate section 123, and the two ends of the intermediate section 123 are connected to the first plug-in section 121 and the second plug-in section 122 respectively. The first plug-in section 121 and the second plug-in section 122 are respectively inserted into the bogie 13.

[0090] In order to avoid interference with the arrangement of the guide block 22, the opening 1200 is in the shape of a strip and extends along the axis of the intermediate section 123, and the opening 1200 is located in the middle of the axis direction of the intermediate section 123. A flat key groove 1221 is provided at a position close to the end of the second plug-in section 122, and the flat key groove 1221 is used to accommodate a flat key to realize transmission connection with the clutch 4 through the flat key.

[0091] At the same time, an axle shoulder is provided on the first plug-in section 121 and the second plug-in section 122 respectively, and the axle shoulder is used to install a limiting plate to limit the axial movement of the transfer shaft 12.

[0092] Figure 10 a structural schematic view of another cable guide device provided by the embodiment of the present disclosure, in combination with Figure 10 Optionally, the support 1 further includes a first steel rod 15 and a second steel rod 16, and the first steel rod 15 and the second steel rod 16 are arranged in parallel and are located on the same side of the fixed frame 11. One end of the first steel rod 15 is welded to the fixed frame 11, and the other end of the first steel rod 15 is welded to the ship body. One end of the second steel rod 16 is welded to the fixed frame 11, and the other end of the second steel rod 16 is welded to the ship body. In this way, the cable guide device can be hung on the ship body.

[0093] The above merely describes optional embodiments of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
