Technical Field

[0001] The utility model relates to the technical field of wire rope slings, in particular to a double - helix anti - slip high - strength wire rope device. Background Technique

[0002] A wire rope is a flexible rope twisted by multiple or multi - strand fine steel wires. A wire rope is formed by twisting multiple layers of steel wires into strands, and then taking the rope core as the center, a certain number of strands are twisted into a spiral - shaped rope. In material handling machinery, it is used for lifting, traction, tensioning, and slings.

[0003] At present, for high - strength wire ropes, most of their application scenarios are for hoisting slings to realize the lifting of objects. However, when the existing wire ropes are used for hoisting and locking, the wire ropes are prone to looseness, resulting in poor fit between the pulley and the wire rope, affecting normal use, leading to a shaking and unstable situation and having certain safety hazards. Moreover, the currently used hoisting locks do not have a shock - absorbing effect, making it difficult to form a state of always fitting with the wire rope. As time goes by, it is not conducive to the staff to lock and stop the operation.

A shock - absorbing component adapted to the two pulleys a 4 is arranged on one side of the frame body 3. An additional installation plate 5 is slidably connected to the inner side wall of the frame body 3. Two symmetrically distributed bearing brackets 6 are fixed to the top side wall of the additional installation plate 5. A pulley b 7 is rotatably connected to the inner side wall of the bearing bracket 6. The pulley b 7 is slidably connected to the outer surface of the steel cable body 1. An adjusting component adapted to the pulley b 7 is arranged on one side of the frame body 3.

[0028] It is specifically worth noting that the shock absorption component includes a mounting top plate 8, which is fixed to the inner side wall of the top end of the frame 3. On the bottom side wall of the mounting top plate 8, two symmetrically distributed hinge seats a9 are fixed. A connecting rod 10 is hinged between the hinge seat a9 and the pulley a4; there are two hinge seats b11, and the two hinge seats b11 are symmetrically distributed and fixed to the bottom side wall of the mounting top plate 8. A damper 12 is hinged to one side of the hinge seat b11. On one side wall of the two mutually approaching connecting rods 10, a mounting rod 13 is jointly fixed. The damper 12 is rotationally connected to the mounting rod 13. Two mounting rings 14 are sleeved on the outer surface of the damper 12. On the jointly fixed side wall of the two adjacent mounting rings 14, a spring 15 is fixed. Through the setting of the shock absorption component, the stability effect of the device during movement can be improved, so as to effectively ensure that the pulley b7 is always in a state of being closely attached to the surface of the steel cable body 1, reduce the influence of the tightness of the steel cable body 1 on sliding, further improve the safety of sliding on the surface of the steel cable body 1, and make the sliding movement more flexible.

[0029] It is specifically worth noting that a connecting frame 16 is fixed to the side wall of the top end of the frame 3, and the connecting frame 16 and the mounting top plate 8 are fixed by a plurality of bolts 17. Through the setting of the connecting frame 16, the connection strength between the frame 3 and the mounting top plate 8 can be improved, so as to greatly enhance the firmness of the mounting top plate 8 and the frame 3.

[0030] It is specifically worth noting that the adjustment component includes a threaded hole 18, which is opened on the side wall of the bottom end of the frame 3. A threaded rod 19 is threadedly connected to the threaded hole 18. One end of the threaded rod 19 is fixed with a runner 20.

[0033] It is worth mentioning that the outer surface of the steel cable body 1 is provided with two anti-slip grooves 24 which are arranged in a staggered distribution. The central axis of the steel cable body 1 is arranged in a colinear manner with the central axis of the mounting base 2. Through the staggered anti-slip grooves 24, the stability of the pulley when sliding on the surface of the steel cable body 1 can be improved, and the anti-slip effect of the steel cable body 1 is effectively improved, which makes it convenient for the staff to quickly lock the steel cable.

[0034] Working principle: When the steel cable body 1 is needed, first ensure that the steel cable body 1 is fixed at the two mounting bases 2, and by rotating the rotating wheel 20, the threaded rod 19 is rotated synchronously, and the threaded transmission effect between the threaded rod 19 and the threaded hole 18 is utilized to make the mounting plate 5 move upward after being subjected to force, thereby driving the supporting bracket 6 and the pulley b7 to move upward synchronously until the two pulleys b7 are completely in contact with the outer surface of the steel cable body 1, and the elastic effect between the damper 12 and the spring 15 is utilized to ensure that the two pulleys a4 are always in contact with the outer surface of the steel cable body 1.
