[0026] Reference Figure 1-Figure 5 , a high-safety mechanical processing sling with automatic unhooking, comprising a sling body 1, a hook 2 is provided at the bottom of the sling body 1, and an automatic unhooking component is provided inside the hook 2;
[0027] The automatic unhooking component includes a moving component and a self-locking component. The moving component includes a moving block 3, and the self-locking component includes a second rack plate 12. The moving block 3 is used to drive the second rack plate 12 to self-lock and unhook the hook 2.
[0028] Reference Figure 1-Figure 5The moving assembly also includes a connecting rod 5, the top of the connecting rod 5 is fixedly connected to the bottom of the moving block 3, the bottom end of the connecting rod 5 is fixedly connected to a first rack plate 6, a through hole is opened on one side of the hook 2, the bottom end of the first rack plate 6 is fixedly connected to a telescopic rod 7, the telescopic rod 7 passes through the through hole and is fixedly connected to the inner bottom wall of the hook 2, the bottom end of the first rack plate 6 is fixedly connected to a telescopic spring 8, the bottom end of the telescopic spring 8 is fixedly connected to the inner bottom wall of the hook 2, the telescopic spring 8 is sleeved on the outer wall of the telescopic rod 7, the internal rotation of the hook 2 is connected to the first rotating shaft, the outer wall of the first rotating shaft is fixedly connected to the first gear 9, the internal rotation of the hook 2 is connected to the second rotating shaft, the outer wall of the second rotating shaft is fixedly connected to the second gear 10, the internal rotation of the hook 2 is connected to the third rotating shaft, the third rotating shaft The outer wall of the shaft is fixedly connected with a third gear 11, the first gear 9 is meshed with the second gear 10, the second gear 10 is meshed with the third gear 11, the first gear 9 is meshed with the first rack plate 6, the interior of the hook 2 is slidably connected with a second rack plate 12, the second rack plate 12 is meshed with the third gear 11; a fixing groove 13 is provided on one side of the hook 2, the second rack plate 12 penetrates one side of the hook 2 and is plugged into the fixing groove 13, and the unhooking component can realize automatic unhooking when the hook 2 puts down the weight, specifically, when the rope on the weight is hung on the hook 2, when the weight is lifted, the moving block 3 will move downward due to the weight, and since the rope groove in the middle of the hook 2 is a rope groove for accommodating the rope of the weight, the rope can be limited to move left and right during transportation, and the moving block 3 The two sides just stick to the inner wall of the rope groove to move up and down. When the moving block 3 moves to a certain position, when the end of the moving block 3 close to the hook head 4 moves to expose the through hole of the second rack plate 12 passing through the hook 2, at this time, the first rack plate 6 at the bottom of the moving block 3 is just meshed with the first gear 9, and the first rack plate 6 continues to move downward to drive the first gear 9 to rotate clockwise, and the clockwise rotation of the first gear 9 drives the second gear 10 to rotate counterclockwise, and the counterclockwise rotation of the second gear 10 drives the third gear 11 to rotate clockwise, and the clockwise rotation of the third gear 11 drives the second rack plate 12 to slide out to the right, so when the through hole of the second rack plate 12 passing through the hook 2 is exposed, the second rack plate 12 slides out to the right, and the moving block 3 moves to the bottom due to the weight. When the movable block 3 moves to the bottom, the movable block 3 is just located below the second rack plate 12. At this time, one end of the second rack plate 12 is just plugged into the fixed groove 13, so that the hook 2 will be self-locking when in use to prevent the lifting rope from falling during lifting. When the hook 2 puts down the heavy object, the movable block 3 will disappear as the weight pressure disappears, and the telescopic spring 8 at the bottom will drive the movable block 3 to reset. At this time, the movable block 3 will gradually rise. While the movable block 3 rises, the second rack plate 12 will retract into the inside of the hook 2. Before the movable block 3 rises to the opening of the second rack plate 12 that passes through the hook 2, the second rack plate 12 will be completely retracted. The movable block 3 stops when it rises to be flush with one end of the hook head 4. At this time, the lifting rope will naturally slide down due to the inclined surface, thereby realizing the function of automatic unhooking.Avoiding the phenomenon of manual unhooking causing operational errors, automatic unhooking can improve the overall processing efficiency and provide a certain guarantee for the safety of the staff.
[0029] Reference Figure 1-Figure 4 A protective pad is provided on the outer wall of the moving block 3, and a hook head 4 is provided on one side of the hook 2. The hook head 4 and the moving block 3 are both inclined. The moving block 3 can be easily pressed through the protective pad. The hook head 4 and the moving block 3 are both inclined, so that the lifting rope can slide down the inclined surface directly when the moving block 3 is reset.
[0030] Reference Figure 1 and Figure 2 The top of the hook 2 is fixedly connected with a connecting head 14, which is rotatably connected to the sling body 1. A lead wheel 15 is provided on the top of the sling body 1. The bottom end of the hook 2 is fixedly connected with an auxiliary ring 16. The auxiliary ring 16 can be used to pick up the hook 2 when the sling body 1 is lowered.
[0031] Working principle: when the lifting rope on the heavy object is hung on the hook 2, when the heavy object is lifted, the moving block 3 will move downward due to the heavy object. When the moving block 3 moves to a certain position, when the end of the moving block 3 close to the hook head 4 moves to expose the opening of the second rack plate 12 passing through the hook 2, at this time, the first rack plate 6 at the bottom of the moving block 3 is just engaged with the first gear 9. The first rack plate 6 continues to move downward to drive the first gear 9 to rotate clockwise, and the clockwise rotation of the first gear 9 drives the second gear 10 to rotate counterclockwise. The counterclockwise rotation of the second gear 10 drives the third gear 11 to rotate clockwise, and the clockwise rotation of the third gear 11 drives the second rack plate 12 to slide out to the right. Therefore, when the opening of the second rack plate 12 passing through the hook 2 is exposed, the second rack plate 12 slides to the right. When the lifting block 3 is lifted up, the second rack plate 12 will be retracted into the hook 2, and the lifting block 3 will stop when it rises to be flush with one end of the hook head 4. At this time, the lifting rope will naturally slide down due to the inclined surface.
[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
