Detailed ways

As shown in Figures 1, 2, 3, and 4, a wire rope anti-swing device for an explosion-proof single-girder crane includes a hoist 1, a wire rope 1 2 and a hook, and two ends of the hoist 1 are respectively fixedly connected with a support frame 3 , a horizontally arranged connecting shaft 4 is rotatably connected in the support frame 3, and the connecting shaft 4 is powered by a deceleration motor 5. The connecting shaft 4 is fixedly connected with a drum 6, and the drum 6 is wound with a wire rope two 7, two wire rope two 7 The bottom is connected with an anti-swing frame 8, the anti-swing frame 8 is arranged below the hoist 1, and a plurality of sleeves one 9 are set in the anti-swing frame 8, and the number of the sleeves one 9 is at least 2, and each sleeve is One 9 is connected by a spring 11, the spring 11 adopts a compression spring, a fixed rod 10 is fixedly connected between the outermost sleeve 1 9 and the anti-swing frame 8, and the wire rope 1 2 passes through the innermost sleeve 1 9 , the wire rope 1 2 runs through the innermost sleeve 1 9 and extends to the bottom of the anti-swing frame 8. The bottom of the wire rope 1 2 is connected with the hook, which can prevent the wire rope 1 2 and the hoisting hook from rising and falling. The swing of the amplitude limits the swing range of the wire rope-2.

The first gear 12 is installed on the connecting shaft 4, and the second gear 13 is installed on the output shaft of the deceleration motor 5, which is meshed with the first gear 12. The deceleration motor 5 provides power, and drives the drum 6 through the transmission of the first gear 12 and the second gear 13. Rotating, so that the wire rope 2 7 wound on the drum 6 descends and ascends, thereby driving the anti-swing frame 8 to ascend and descend.

The support frame 3 is a rectangular frame structure, and the end of the support frame 3 is fixedly connected with the end of the hoist 1 . The top of the anti-swing frame 8 is connected with a lifting ring 14, and the lifting ring 14 adopts a lifting ring screw. The lifting ring 14 is used to be fixedly connected with the wire rope 2 7, and the two ends of the top surface of the anti-swing frame 8 are fixedly connected with inclined connecting rods 15. A vertically arranged sleeve 2 16 is fixedly connected between the connecting rods 15 , the wire rope 2 7 passes through the second sleeve 16 , the connecting rod 15 and the second sleeve 16 form a triangle, and the triangle has stability and increases anti-swing The stability of the rack 8 during ascent and descent.

The inner layer of the innermost sleeve one 9 is connected with a protective layer 17, the wire rope one 2 passes through the sleeve one 9, the inner side of the sleeve two 16 is also connected with a protective layer 17, and the protective layer 17 can be made of rubber. In this way, the wear resistance of the first sleeve 9 and the second sleeve 16 are respectively increased, and the service life of the first sleeve 9 and the second sleeve 16 is prolonged.

The number of the sleeve one 9 is at least two, and the diameter of the sleeve one 9 increases sequentially from the inside to the outside.

Both ends of the drum 6 are integrally connected with baffles 18 , and the baffles 18 play a role in limiting the position of the second wire rope 7 .

Working process: the lifting of the wire rope 1 2 drives the hook to lift the goods, the wire rope 1 2 passes through the sleeve 1 9, and when the wire rope 1 2 swings during the movement, the wire rope 1 2 will contact with the sleeve 1 9. The inner walls are in contact with each other, and a spring 11 is connected to the outside of the sleeve one 9, which acts as a buffer for the sleeve one 9. When the wire rope one 2 moves, the deceleration motor 5 is started, and the drum 6 rotates the wire rope two 7 to also move, and the wire rope two 7 passes through the second sleeve 16, and the two sides of the second sleeve 16 are fixedly connected with connecting rods 15 to prevent the second wire rope 7 from swinging during the movement, thereby limiting the swing range of the second wire rope 7.
