[0027] Reference Figure 1-6 A cargo ship lifting auxiliary device comprises a crane arm 1, a fixing plate 2 is fixedly installed at the end of the crane arm 1, a guide rod 3 is slidably penetrated on the surface of the fixing plate 2, a hook 11 is arranged at the bottom end of the guide rod 3, two mounting plates 6 are fixedly installed on the surface of the fixing plate 2, a winding wheel 5 is rotatably connected between the two mounting plates 6, a high torque motor 4 is fixedly installed on the side wall of the mounting plate 6, an output shaft port of the high torque motor 4 is fixedly connected to the winding wheel 5, a connecting block 13 is fixedly installed at the bottom of the fixing plate 2, a lifting rope 7 is fixedly connected to the surface of the connecting block 13, a through hole 9 is opened on the surface of the guide rod 3 near the bottom, the lifting rope 7 penetrates through the through hole 9 and is wound around the winding wheel 5, and the fixing plate 2 is fixedly installed on the crane arm during use. 1, when lifting, the crane arm 1 is used to move the hook 11 to the top of the object, and then the high-torque motor 4 is used to drive the roller reel 5 to rotate, so as to loosen the rope 7. During the loosening process, the guide rod 3 will slide downward under the influence of gravity until the hook 11 can be hung on the object, and then the high-torque motor 4 is used to rotate the reel 5 in the opposite direction, so that the rope 7 is rolled up. As the rope 7 becomes shorter and shorter, the guide rod 3 will slide upward under the action of the rope 7, so that the object is lifted up. By arranging the hook 11 at the bottom of the guide rod 3, the guide rod 3 can only slide in the vertical direction, so that rotation will not occur during lifting, and even less will swing, thereby reducing safety hazards.

[0028] Furthermore, a pulley 8 is rotatably connected inside the through hole 9, and the suspension rope 7 is in contact with the pulley 8. By setting the pulley 8, the wear of the suspension rope 7 and the guide rod 3 can be reduced, and the setting of the pulley 8 can form a pulley 8 group, thereby reducing the traction force on the high-torque motor 4.

[0029] Furthermore, a round block 17 is fixedly installed on the top of the hook 11, and a fixed block 10 is fixedly installed on the bottom end of the guide rod 3. A receiving groove 16 is opened inside the fixed block 10, and the round block 17 is rotatably connected inside the receiving groove 16. A limiting mechanism for limiting the round block 17 is provided inside the fixed block 10. The hook 11 is connected to the fixed block 10 through the round block 17, so that the hook 11 can rotate. The rotation of the round block 17 can be limited by setting a limiting mechanism to avoid the rotation of the goods during the lifting process. When placing the goods, in order to place the goods at a required angle, the restriction can be released and the goods can be rotated manually for easy operation.

[0030] Furthermore, the limiting mechanism includes a limit plate 12, which is composed of a circular plate and extension rods fixedly installed on both sides of the circular plate. Vertical grooves 15 are provided on both sides of the fixed block 10, and the vertical grooves 15 are connected to the receiving grooves 16. The extension rods pass through the vertical grooves 15. A spring 14 is fixedly installed on the top of the limit plate 12, and the end of the spring 14 away from the limit plate 12 is fixedly connected to the top wall of the receiving groove 16. The bottom of the limit plate 12 is evenly fixedly connected with limiting teeth 18, and the top of the circular block 17 is evenly provided with limiting tooth grooves that are compatible with the size of the limiting teeth 18. When the limiting mechanism is in use, the limit plate 12 is subjected to the elastic force of the spring 14, so that the limiting teeth 18 at the bottom of the limit plate 12 and the limiting tooth grooves at the top of the circular block 17 are engaged with each other, thereby forming a restriction. When the restriction needs to be released, the extension rod can be manually pulled upward to disengage the limiting teeth 18 at the bottom of the circular plate from the limiting tooth grooves, thereby releasing the restriction.

[0031] Furthermore, the bottom wall of the receiving groove 16 is evenly provided with balls 19, and the balls 19 and the receiving groove 16 are movably connected. By providing the balls 19, the round block 17 can rotate more smoothly inside the receiving groove 16, reducing the rotation resistance.

[0032] Furthermore, a square hole is opened on the surface of the fixing plate 2 , and the suspension rope 7 passes through the square hole and is wound around the winding wheel 5 .

[0033] In summary, during use, the fixing plate 2 is fixedly installed on the crane arm 1. When lifting, the crane arm 1 is used to move the hook 11 to the top of the object, and then the high-torque motor 4 is used to drive the roller winding wheel 5 to rotate, so as to loosen the lifting rope 7. During the loosening process, the guide rod 3 will slide downward under the influence of gravity until the hook 11 can be hung on the object, and then the high-torque motor 4 is used to rotate the winding wheel 5 in the opposite direction, so that the lifting rope 7 is wound. As the lifting rope 7 becomes shorter and shorter, the guide rod 3 will slide upward under the action of the lifting rope 7, so that the object is lifted. By setting the hook 11 at the bottom of the guide rod 3, the guide rod 3 can only slide in the vertical direction, so that there will be no rotation during lifting, and even less swinging, thereby reducing safety hazards. By setting the pulley 8, the wear of the lifting rope 7 and the guide rod 3 can be reduced, and the setting of the pulley 8 can form a pulley 8 group , reducing the traction force on the high-torque motor 4, the hook 11 is connected to the fixed block 10 through the round block 17, so that the hook 11 can rotate, and the rotation of the round block 17 can be restricted by setting a limiting mechanism to avoid the rotation of the goods during the lifting process. When placing the goods, in order to place the goods at a required angle, the restriction can be released and manually rotated for easy operation. When the limiting mechanism is in use, the limit plate 12 is subjected to the elastic force of the spring 14, so that the limiting teeth 18 at the bottom of the limit plate 12 and the limiting tooth groove at the top of the round block 17 are engaged with each other, thereby forming a restriction. When the restriction needs to be released, the extension rod can be manually pulled upward to disengage the limiting teeth 18 at the bottom of the circular plate from the limiting tooth groove, thereby releasing the restriction. By setting the ball 19, the round block 17 can be rotated more smoothly inside the accommodating groove 16, reducing the rotation resistance.
