Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

As shown in fig. 1 to 4, an embodiment of the present invention provides a flexible steel wire rope sling, including a steel wire 1 for bearing pressure, a plurality of steel wire ropes 1 forming a spiral steel wire rope 6, a plurality of spiral steel wire ropes 6 spirally arranged for avoiding the spiral steel wire rope 6 from being scattered, a first flexible layer 2 fixedly connected to an outer surface of the spiral steel wire rope 6, a first elastic rope 3 arranged between the first flexible layer 2 for bending the spiral steel wire rope 6, a hose 5 arranged inside the first flexible layer 2 for avoiding friction between the spiral steel wire ropes 6, the hose 5 being made of PE and filled with a spiral metal wire for avoiding easy deformation.

The side surface of the first flexible layer 2 and the outer side of the first elastic rope 3 are provided with a second elastic rope 4, the outer surface of the second elastic rope 4 is provided with a flexible sleeve 7 for protecting the spiral steel rope 6, the first elastic rope 3 and the second elastic rope 4 are made of terylene and polypropylene fibers, the flexible sleeve 7 is woven by DuPont wires, terylene and nylon fibers which are imported in a four-strand circular weaving mode, and one strand of each of the DuPont wires 2, the terylene and the nylon is used for having tensile effect, the upper surface of the flexible sleeve 7 is fixedly connected with a fixed sleeve 8, the inner surface of the fixed sleeve 8 is in contact with the spiral steel rope 6, the upper surface of the fixed sleeve 8 is provided with two holes, the upper surface of the spiral steel rope 6 is provided with a circular connecting rope 9, the circular connecting rope 9 is formed by dividing the spiral steel rope 6 into two strands, and the upper surface of the circular connecting rope 9 extends to the outer side of the holes, the ring type connecting rope 9 is welded to increase the welding area and facilitate the fixation, and the outer surface of the ring type connecting rope 9 is provided with a connecting cylinder 10 for the ring type connecting rope 9 to be fixed.
