Document Type and Number:
WIPO Patent Application WO/2022/099738
Kind Code:
A1
Abstract:
An annular lifting sling, comprising a lifting sling body (1), a protective mechanism, and a position adjusting mechanism. The protective mechanism comprises two identical cut-preventing edge sleeves (2) symmetrically and fixedly connected to either side of the lifting sling body (1). The cut-preventing edge sleeves (2) comprise several H-shaped blocks (201), several cross-shaped blocks (202), and several first bolts (203). The several H-shaped blocks (201) and the several cross-shaped blocks (202) are alternately provided; moreover, adjacent H-shaped blocks (201) and cross-shaped blocks (202) are rotatively connected to each other. The H-shaped blocks (201) and the cross-shaped blocks (202) are provided at the side in proximity to the lifting sling body (1) with mounting cavities (204). The first bolts (203) are threadedly connected between the top part and the bottom part of the mounting cavities (204). The position adjusting mechanism comprises an engaging block parent end (3), an engaging block child end (4), and mounting holes (5). The engaging block parent end (3) comprises a square barrel body (301), second bolts (302), and engaging grooves (303). The square barrel body (301) is movably sleeved on the surface of the lifting sling body (1). Two identical second bolts (302) are symmetrically sleeved on the sidewall of the square barrel body (301). The two second bolts (302) respectively are sleeved within two mounting holes (5). Identical engaging grooves (303) are equidistantly provided on the top part and the bottom part at one side of the square barrel body (301). The engaging block child end (4) comprises a housing (401), fixed columns (402), and third bolts (403). The housing (401) is sleeved at the distal end of the lifting sling body (1). Several identical fixed columns (402) are equidistantly and fixedly connected to the top end and the bottom end at one side of the housing (401). The annular lifting sling, by means of the two cut-preventing edge sleeves (2), effectively prevents the lifting sling body (1) from breaking due to either edge scraping other sharp objects during use; with the engaging block child end (4) and the engaging block parent end (3) engaging each other to connect the lifting sling body (1), when the radius of the ring formed by the lifting sling needs to be changed, an adjustment can be made by changing the position of the engaging block parent end (3), the structure is simple, and use is convenient.
