Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire rope rigging, and in particular relates to a limiting structure of a high-strength rigging steel rope. Background Art

[0002] Wire rope slings are made of wire rope as raw material and are mainly used for lifting, traction, tensioning and carrying. Wire rope slings have the characteristics of high strength, light weight, stable operation, and not easy to break suddenly. They are widely used in steel, chemical, transportation, ports and other industries. The types of wire ropes used include phosphating coated wire rope, galvanized wire rope, stainless steel wire rope and smooth wire rope.

[0003] The bottom of the wire rope sling is generally a hook, which is hooked with the external component for lifting. However, during the lifting process, the part hooked by the hook is prone to shaking inside the hook, which is not only not conducive to ensuring stability during lifting, but also has the risk of falling off. Therefore, it is necessary to design a limiting structure for the wire rope sling to solve this problem. Utility Model Content

[0006] A wire rope and a hook fixedly connected to the bottom end of the wire rope;

[0007] The limiting structure includes an end slot provided at the end of the hook, an elastic belt fixedly connected to the inside of the end slot, and a hollow slot extending through the surface of the hook;

[0008] The locking assembly connected between the end of the elastic belt and the hook surface comprises a fixed connecting piece fixedly connected to the end of the elastic belt, a fixed plate fixed to the hook surface, and a threaded rotating rod threadedly connected between the fixed connecting piece and the fixed plate.

[0009] Preferably, a rotary handle is fixed to the bottom end of the threaded rotary rod, and the surface of the rotary handle is provided with anti-slip grooves.

[0010] Preferably, the threaded rotating rod passes through the fixing plate, and the top end is threadedly connected to the fixing connecting piece.

[0011] Preferably, the locking assembly further comprises a connecting rope, and two ends of the connecting rope are respectively fixedly connected to the rotating handle and the fixing plate.

[0012] Preferably, a damping assembly is provided on the inner bottom surface of the hook, and the damping assembly includes a mounting groove opened on the inner bottom surface of the hook, a mounting back plate fixedly installed inside the mounting groove, and a rubber pad fixed on the outer surface of the mounting back plate.

[0013] Preferably, the damping assembly further includes an anti-slip groove formed on the outer surface of the rubber pad.

[0014] Preferably, the damping assembly further comprises a clamping strip fixed on the surface of the mounting back plate, and a clamping slot provided on the inner wall of the mounting slot and plugged into the clamping strip.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] After hooking the external component with the hook, the elastic belt can be moved to allow the fixed connecting plate to pass through the hollow groove and be fixedly connected to the fixed plate. At this time, the elastic belt is protected on the outside of the hooked part of the external component. In this way, the stability of the external component can be improved, and the hooked position is not easy to shake or slide inside the hook, and it can also avoid falling off the hook. The limiting effect of the limiting structure on the external component can improve the stability and safety of the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS
