[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0029] like Figures 1 to 7As shown, a marine lifting safety auxiliary structure includes a hook body 1 and a locking buckle 2 for closing the opening of the hook body 1. The locking buckle 2 includes a fixed end 3 and a closed end 4. The fixed end 3 is provided with a docking hole 19 and is used to connect the locking buckle 2 to the lifting mechanism of the lifting device. The closed end 4 is used to close the opening of the hook body 1. In actual use, after the hook body 1 hooks the wire rope used to fix the equipment, under the action of force, the closed end 4 can promptly close the opening of the hook body 1 with the locking buckle 2, effectively preventing the hook body 1 from shaking and causing the locking buckle 2 to fail to effectively close the opening of the hook body 1, thus improving the safety performance of marine equipment during the lifting process and also improving the ease of use.

[0030] A mounting groove 5 for connecting the hook body 1 is provided between the fixed end 3 and the closed end 4. Connecting holes 6 are provided on both sides of the inner wall of the mounting groove 5. A rotatable pin 7 is inserted through the connecting hole 6. The connecting end of the hook body 1 and the mounting groove 5 is hinged to the pin 7. This allows the hook body 1 to be securely installed in the mounting groove 5. The hinged connection between the hook body 1 and the rotatable pin 7 makes it easy for the hook body 1 to rotate with the pin 7, and it is easy to manually adjust the angle at which the hook body 1 hooks the wire rope.

[0031] When the hook 1 hooks the wire rope, if the wire rope has a small or thin diameter, a portion of the wire rope may slip out through the gap between the closed end 4 and the opening of the hook 1, which may pose a safety hazard. Therefore, a through hole 8 is provided at the open end of the hook 1, and a connecting rod 9 passes through the through hole 8. Both ends of the connecting rod 9 are provided with fastening components to strengthen the function of the lock 2 in closing the opening of the hook 1. The ends of the fastening components are detachably fixed inside the closed end 4. This arrangement can strengthen the sealing effect of the closed end 4 on the opening of the hook 1, reduce safety hazards, and enhance the protection of the equipment.

[0032] Specifically, the connecting rod 9 has symmetrically arranged fixing grooves 10 at both ends, and threaded holes 11 coaxially arranged with the connecting rod 9 at both ends. Fixing members 12 that are screwed into the threaded holes 11 are fixedly installed at both ends of the connecting rod 9. The fastening assembly is fixedly installed in the fixing groove 10 and located between the connecting rod 9 and the fixing member 12. In actual use, the fastening assembly is sleeved in the fixing groove 10, and then the fixing member 12 is screwed into the threaded hole 11 to fix the fastening assembly in the fixing groove 10. In this way, the fastening assembly will not slip out of the fixing groove 10. When it is necessary to remove the fastening assembly, simply unscrew the fixing member 12 first, and then remove the fastening assembly from the fixing groove 10. It is convenient to use and easy to operate manually.

[0033] More specifically, the fastening assembly includes a connecting plate 13 fixedly installed in the fixing groove 10. One end of the connecting plate 13 fixed in the fixing groove 10 is provided with a fixing hole 14 that matches the fixing groove 10. Specifically, the diameter of the fixing hole 14 matches the outer diameter of the fixing groove 10, so that the connecting plate 13 can be firmly fixed in the fixing groove 10.

[0034] One end of the connecting plate 13 near the opening of the hook body 1 is fixed in the fixing groove 10. In order to achieve the purpose of strengthening the sealing effect of the closed end 4 on the opening of the hook body 1, the end of the connecting plate 13 away from the opening of the hook body 1 needs to be fixed to the closed end 4. Therefore, a limiting block 15 is provided at the end of the connecting plate 13 away from the fixing groove 10. The limiting block 15 can extend into the closed end 4. Specifically, the closed end 4 is provided with a limiting hole 16. Several protrusions 17 are arranged in a circumferential array inside the limiting hole 16. Several arc grooves 18 are arranged in a circumferential array outside the limiting block 15. The arc grooves 18 and the protrusions 17 are arranged in a one-to-one correspondence. In this way, the limiting block 15 can be locked inside the limiting block 15, thereby achieving the purpose of strengthening the sealing effect of the closed end 4 on the opening of the hook body 1.

[0035] When it is necessary to remove the connecting plate 13 from the limiting hole 16, first remove the fixing piece 12 so that the fixing hole 14 on the connecting plate 13 is disengaged from the fixing groove 10, that is, the connecting plate 13 is disengaged from the fixing groove 10. Then remove the connecting plate 13 so that the limiting block 15 is disengaged from the limiting hole 16, and the removal of the connecting plate 13 can be completed.

[0036] Since the locking buckle 2 will be connected to the lifting mechanism of the hoisting device, in order to reduce the damage to the locking buckle 2 caused by the friction generated when the lifting mechanism is connected to the docking hole 19 of the fixed end 3, a buffer pad 20 is glued and installed inside the docking hole 19. This can effectively reduce the wear on the locking buckle 2.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
