[0001] The present invention relates to the technical field of ship fairlead bases, and particularly to a double fairlead base suitable for use in a compact space. Background Art

[0002] A fairlead is a device used on ships or other waterborne vehicles. Its main function is to guide the cable to ensure that the cable is moored or towed safely in a fixed position. Fairleads are usually designed as circular or oval openings installed at appropriate positions on the hull to facilitate the passage of the cable. They can be simple openings or equipped with special fairlead devices such as fairlead rings or fairlead hooks to reduce cable wear and improve operational safety. Therefore, there is a particular need for a double fairlead base suitable for use in a compact space.

At this time, insert the fixing block 22 into the first fixing hole 21 and thread-connect it with the second connecting block 26. At this time, insert the first connecting block 23 into the connecting groove 24 opened on one side surface of the mounting block 22. Put the rivet 29 through the mounting hole 28 opened above the cross beam 12 and insert it into the first fixing groove 27 opened on one side surface of the first connecting block 23, so that the connecting frames 14 are firmly fixed. At the same time, tightly connect the two connected double fairlead base bodies 1 through the rivet 29.

[0021] Further, the double fairlead base body 1 includes a base 11, a fairlead 12, a clamping block 13, a connecting frame 14 and a support frame 15. The fairlead 12 is fixed on the base 11. The clamping block 13 is fixed on the outer wall of the base 11. The connecting frame 14 is installed on the outer wall of the clamping block 13. The support frame 15 is installed on the outer wall of the base 11. Through the cooperation of the connecting frame 14 and the clamping block 13, connect the two connected fairleads 12 with the base 11.

[0022] Further, the first threaded rod 25 and the second connecting block 26 form a threaded connection. The outer wall dimension of the second connecting block 26 matches the inner wall dimension of the connecting groove 24. Through the setting of the connecting groove 24, during use, the connecting groove 24 and the second connecting block 26 are used in cooperation to fix the two connected connecting frames 14.

Then, the hydraulic shock absorber 34 is installed on the connecting seat 32 through the connecting shaft 33. When the base 11 is under long-term load and vibration, the hydraulic shock absorber 34 will absorb the energy transmitted from the base 11 to the deck, and the spring 36 will further absorb the transmitted energy to complete shock absorption and buffering, thereby improving the support strength and service life of the double fairlead base body 1.

[0025] Furthermore, the first backing plate 35 is provided on one end surface of the spring 36, and the second backing plate 37 is connected to the other end surface of the spring 36. Through the setting of the spring 36, during use, the spring 36 can absorb the energy not absorbed by the hydraulic shock absorber 34 to complete shock absorption and buffering.

[0026] Furthermore, the hydraulic shock absorbers 34 are symmetrically installed with respect to the central axis of the connecting plate 31, and the inner wall size of the spring 36 matches the outer wall size of the hydraulic shock absorber 34. Through the setting of the hydraulic shock absorber 34, during use, the hydraulic shock absorber 34 can absorb, slow down, and reduce various vibrations to achieve the effect of shock absorption, so as to extend the service life of the double fairlead base body 1.

[0027] Furthermore, a fixing mechanism 4 is provided on the outer wall of the double fairlead base body 1. The fixing mechanism 4 includes a bolt 41, a nut 42, a second fixing hole 43, a second fixing groove 44, a bolt 45, a top plate 46, a second threaded rod 47 and a threaded knob 48. The outer wall of the support frame 15 is penetrated and connected with a bolt 41. One end surface of the bolt 41 is fixedly connected with a nut 42. A second fixing hole 43 is formed on the outer wall of the bolt 41. A second fixing groove 44 is formed on the outer wall of the nut 42. A bolt 45 is fixedly connected to the inner surface of the second fixing hole 43. The outer wall of the bolt 41 is penetrated and connected with a top plate 46. The outer wall of the top plate 46 is welded with a second threaded rod 47. A threaded knob 48 is fixedly connected to the outer surface of the second threaded rod 47. Through the settings of the bolt 41, the nut 42, the second fixing hole 43, the second fixing groove 44, the bolt 45, the top plate 46, the second threaded rod 47 and the threaded knob 48, during use, the support frame 11 and the top plate 46 are fixed to both sides of the arc-shaped frame 12 through the bolt 41, and then the nut 42 is fixed to one end of the bolt 41 through the bolt 45. When installing the support frame 15, rotate the threaded knob 48, and the threaded knob 48 will push the second threaded rod 47 and the top plate 46 towards the base 11, thereby improving the overall firmness and support strength of the support frame 15.

[0028] Furthermore, the top plate 46 is symmetrically installed with respect to the central axis of the support frame 15, and the second threaded rod 47 is symmetrically installed with respect to the central axis of the top plate 46. Through the setting of the second threaded rod 47, during use, rotating the threaded knob 48 will push the second threaded rod 47 towards the top plate 46, thereby fixing the top plate 46 to both sides of the support frame 15 and preventing the support frame 15 from deforming inward due to excessive pressure during use.

[0029] Furthermore, the second fixing groove 44 is symmetrically opened with respect to the central axis of the nut 42, and the outer wall dimension of the bolt 45 matches the inner wall dimension of the second fixing hole 43. Through the setting of the bolt 45, during use, the bolt 45 can effectively prevent the nut 42 from loosening and falling off due to long-term load and vibration.

[0030] Working principle: Through the settings of the first fixing hole 21, fixing block 22, first connecting block 23, connecting groove 24, threaded rod 25, second connecting block 26, first fixing groove 27, mounting hole 28 and rivet 29, during use, insert the connecting piece into the inside of the support frame 15, and align the first fixing holes 21 on both sides of the support frame 15 with the first fixing holes 21 on both sides of the interconnected support frame 15. At this time, insert the fixing block 22 into the first fixing hole 21 and thread-connect it with the second connecting block 26. Then insert the first connecting block 23 into the connecting groove 24 opened on one side surface of the mounting block 22. Place the rivet 29 through the mounting hole 28 opened above the cross beam 12 and insert it into the first fixing groove 27 opened on one side surface of the first connecting block 23, so that the support frames 15 are firmly fixed. At the same time, tightly connect the two connected double fairlead base bodies 1 through the rivet 29. Through the settings of the connecting plate 31, connecting seat 32, connecting shaft 33, hydraulic shock absorber 34, first backing plate 35, spring 36 and second backing plate 37, during use, put the spring 36 on the outer wall of the hydraulic shock absorber 34, then use the first backing plate 35 and the second backing plate 37 to fix the spring 36, and then install the hydraulic shock absorber 34 on the connecting seat 32 through the connecting shaft 33. When the base 11 is under long-term load and vibration, the hydraulic shock absorber 34 will absorb the energy transmitted from the base 11 to the deck, and the spring 36 will further absorb the transmitted energy to complete shock absorption and buffering, thereby improving the support strength and service life of the double fairlead base body 1. Fix the support frame 11 and the top plate 46 to both sides of the arc-shaped frame 12 through the bolts 41, and then fix the nut 42 to one end of the bolt 41 through the bolt 45. When installing the support frame 15, rotate the threaded knob 48, and the threaded knob 48 will push the second threaded rod 47 and the top plate 46 towards the base 11, thereby improving the overall firmness and support strength of the support frame 15.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
