Line of centers is the encapsulated coil of a ring-type, and object-line is shape circulation winding in the shape of a spiral along the line of centers periphery, so just can form a ringwise non junction rope bundle.Because each object-line twines around line of centers, the phenomenon that some coil is in relaxed state can not occur, and each object-line is evenly distributed on the cross-sectional plane of endless rope bundle, thus whole piece endless rope bundle stressed evenly, can not cause the waste of material.The band cover is set outside the endless rope bundle has protective effect, prevent to be colluded line or disarray.The number of turns that object-line is wound on the line of centers is decided as required.
In above-mentioned ring-shaped thread-through lifting belt, described line of centers and each object-line are integral structure.In fact, the line of centers of this structure and object-line are same single lines, and the fixing line of centers that promptly forms in back is rolled in the inner of object-line.Also can adopt such structure: line of centers is an osed top non junction toroid, and the inner of object-line is connected on the line of centers.In addition, the said line of centers of the utility model also can be to be twined mutually by the several wire material that shape in the shape of a spiral twines to constitute, and promptly line of centers is identical with the coiling mode of object-line, does not have proper difference.
In above-mentioned ring-shaped thread-through lifting belt, described band cover is woven into cannula-like by flexible material, and the endless rope collar is located at wherein, and the two ends of band cover are connected.The band cover can do up protective effect to endless rope.Before the coiling object-line, earlier this band is enclosed within the line of centers periphery, stitching got final product after coiling was finished.Also can adopt such structure: the entire belt cover is wrapped after the coiling of endless rope bundle is finished.
In above-mentioned ring-shaped thread-through lifting belt, described line of centers and object-line are made by fiber yarn, and line of centers and object-line are multi cord.Advantages such as fiber yarn has the intensity height, and material is light, and be flexible material not only use more conveniently, also have higher safety, can to around people or article not constitute a threat to.
In above-mentioned ring-shaped thread-through lifting belt, described band cover is formed by the fiber yarn braiding.
Compared with prior art, the advantage of this ring-shaped thread-through lifting belt is:
1. integral body is jointless annular, and adopts flexible material to make, and has the structural strength height, and it is very convenient to use, and safety performance is good, even if fracture also not can to around people or property advantage such as cause damage.
