Detailed Description

As shown in fig. 1, 2, 3 and 4, a wire rope anti-swing device of an explosion-proof single-beam crane comprises a winch 1, a wire rope I2 and a hook, wherein two ends of the winch 1 are respectively and fixedly connected with a support frame 3, a horizontally arranged connecting shaft 4 is rotatably connected with the support frame 3, the connecting shaft 4 is powered by a speed reduction motor 5, a roller 6 is fixedly connected with the connecting shaft 4, a wire rope II 7 is wound on the roller 6, the bottoms of the two wire rope II 7 are connected with an anti-swing frame 8, the anti-swing frame 8 is arranged below the winch 1, a plurality of sleeved sleeves I9 are arranged in the anti-swing frame 8, the number of the sleeves I9 is at least 2, each sleeve I9 is connected through a spring 11, the springs 11 are compression springs, a fixing rod 10 is fixedly connected between the outermost sleeve I9 and the anti-swing frame 8, the wire rope I2 passes through the innermost sleeve I9, the steel wire rope I2 penetrates through the innermost sleeve I9 and extends to the position below the anti-swing frame 8, the bottom of the steel wire rope I2 is connected with the lifting hook, the steel wire rope I2 and the lifting hook can be prevented from swinging to a large extent in the ascending and descending processes, and the swinging range of the steel wire rope I2 is limited.

The first gear 12 is mounted on the connecting shaft 4, the second gear 13 meshed with the first gear 12 is mounted on an output shaft of the speed reducing motor 5, the speed reducing motor 5 provides power, and the drum 6 is driven to rotate through transmission of the first gear 12 and the second gear 13, so that the second steel wire rope 7 wound on the drum 6 descends and ascends, and the swing-proof frame 8 is driven to ascend and descend.

The support frame 3 is of a rectangular frame structure, and the end part of the support frame 3 is fixedly connected with the end part of the first winch. The top of the anti-swing frame 8 is connected with a hanging ring 14, the hanging ring 14 is made of hanging ring screws, the hanging ring 14 is used for being fixedly connected with the second steel wire rope 7, connecting rods 15 which are obliquely arranged are fixedly connected to two ends of the top surface of the anti-swing frame 8, a second vertically arranged sleeve 16 is fixedly connected between the two connecting rods 15, the second steel wire rope 7 penetrates through the second sleeve 16, the connecting rods 15 and the second sleeve 16 form a triangle in a surrounding mode, the triangle has stability, and the stability of the anti-swing frame 8 in ascending and descending is improved.
