Description

Round sling with built-in monitoring device

Technical Field

The utility model relates to a built-in monitoring devices's roundsling belongs to rope net application technical field.

Background

Industrial slings are typically made of metal or synthetic materials. Wire rope slings are typically made by twisting together a plurality of metal strands, secured by a large metal sleeve. Synthetic slings are typically composed of a lifting core of synthetic fiber strands and a sheath that protects the core. The core is typically inserted in a direction parallel to the other wires within the core, but may also twist as it penetrates the jacket, a synthetic sling having weight, strength and other advantages over wire rope slings. One of the predominant designs for synthetic slings is the roundsling, in which the sling core forms a continuous loop and the sling is round or oval.

Modern industrial slings may experience load failure and loss due to sling wear or failure, for example, due to the sling fatiguing, overstretching or overloading in current or previous use. When overloaded beyond its rated capacity, the fibers of the load bearing core may be permanently damaged or deformed if the load stretches them beyond their rated strength. When a synthetic fiber sling is overloaded beyond its tensile strength or load-bearing capacity, it is considered damaged and may never recover its normal strength and load-bearing capacity. During field use, the detection of such an overload condition is difficult to visually or otherwise inspect or determine.

In the current art, there is no method available to continuously, directly measure the load on a wire rope or synthetic sling in an industrial or field use environment. Current methods rely solely on detecting overload conditions or indirectly measuring the load, for example, using load sensors or related measurement techniques at the attachment point. These indirect measurements may provide misleading information depending on the configuration of the hoist rigging when used in a lifting operation.

Often, overload, fatigue or damage to the sling material is not readily apparent as a result of visual inspection, particularly considering that the size or length of a certain sling is large, or because the load-bearing core is hidden within the cover. If the structure of the object being lifted changes, the sling may no longer be able to lift the load according to its maximum rated load capacity or load limit. Fatigue or structural weakness can pose a threat to operators and assemblers using damaged slings.

In addition, the structural ability of the sling is early warned in advance by monitoring or predicting the structural health condition of the sling, so that the service life of the sling can be prolonged, the necessity of replacing the sling is reduced, and the cost and the unnecessariness of replacing the sling are reduced. Furthermore, knowing the service life, environmental factors and overload history of a particular sling allows the lifting worker to determine the task and select the safest, most appropriate equipment for each rigging.
