Description

Technical Field

[0001] The utility model relates to the technical field of anti-winding of hooks and ropes, in particular to an anti-winding device for hooks and ropes. Background Art

[0002] In production operations, especially automobile manufacturing operations, lifting equipment is often required to lift production materials or molds through two steel wire ropes. During the lifting process, due to unbalanced force, the lifting parts are prone to rotation. At this time, the top of the steel wire rope will be entangled, affecting work efficiency and posing a safety hazard. After the lifting is completed, the steel wire rope is no longer under force. At this time, due to the change in force, the steel wire rope is very likely to be entangled. If it is not handled in time before the next lifting, the distance between the contact part of the two steel wire ropes and the lifting parts will become smaller, causing the lifting parts to fall due to imbalance during the lifting process, posing a safety hazard; and the long-term irregular winding of the steel wire rope will seriously affect the service life of the steel wire rope.

[0003] At present, the anti-winding device of the hook and rope in the prior art is usually used to support the rope to prevent winding. When in use, since the device is combined with the rope, after long-term use, the rope and the device will be worn and need to be replaced, but the device cannot be conveniently disassembled from the rope, so the device and the rope cannot be replaced separately, and there is a problem of inconvenient disassembly. In addition, when in use, the rope lifts the object, so that the rope is stressed and keeps it straight, which squeezes the device, causing the device and the rope to quickly wear and damage, and there is a problem of being unable to protect the rope and the device.
