An insertion column 301 is fixedly connected to the middle of one side of the first connecting piece 3. A first through hole 303 is arranged in the middle of the insertion column 301. An external thread part 302 is arranged on the outer end face of the insertion column 301. The other end of the anti-corrosion steel wire rope 1 is fixedly connected to a second connecting piece 4. An insertion pipe 401 is fixedly connected to one side of the second connecting piece 4. A second through hole 403 is arranged in the middle of the insertion pipe 401. An internal thread part 402 is arranged on the inner end face of the insertion pipe 401.
[0024] Furthermore, the inside of the glass fiber mesh layer 103 and the plurality of single-strand twisted steel wire bundles 2 are filled with cotton ropes 102. The single-strand twisted steel wire bundle 2 includes a plurality of steel wires 201 twisted and connected to each other. An isolation sleeve 202 is fixedly connected together on the outside of the plurality of twisted and connected steel wires 201. The isolation sleeve 202 is used to isolate between the plurality of single-strand twisted steel wire bundles 2 to prevent mutual extrusion and wear between the plurality of single-strand twisted steel wire bundles 2.
[0025] Furthermore, a plurality of wear-resistant rubber strips 105 are fixedly connected in an annular array on the outside of the anti-corrosion rubber layer 104. The wear-resistant rubber strips 105 and the anti-corrosion rubber layer 104 are fixedly connected by hot melt adhesive. The wear-resistant rubber strips 105 are used to improve the wear resistance of the entire anti-corrosion steel wire rope 1.
[0026] Furthermore, between the two anti-corrosion steel wire ropes 1, the insertion column 301 of the first connecting piece 3 on one anti-corrosion steel wire rope 1 is inserted into the insertion pipe 401 of the second connecting piece 4 on the other anti-corrosion steel wire rope 1 and is fixed by screwing the external thread portion 302 and the internal thread portion 402, so as to connect the two anti-corrosion steel wire ropes 1.
[0027] Furthermore, after the insertion column 301 and the insertion pipe 401 are fixedly connected, the first through hole 303 and the second through hole 403 are vertically aligned, and a pin rod 5 is connected to the first through hole 303 and the second through hole 403 together.
[0028] Furthermore, the upper end of the pin rod 5 extends out of the upper end of the second through hole 403 and is fixedly connected with a limiting piece. The lower end of the pin rod 5 extends out of the lower end of the second through hole 403 and rectangular grooves 501 are arranged on both sides.

A spring 602 is connected between the inner end faces of the limiting rods 6 and the inner side end faces of the interiors of the rectangular grooves 501. When the lower end of the pin rod 5 extends out of the lower end of the second through hole 403, the limiting rods 6 are pushed out by the spring 602, causing the limiting rods 6 to deflect through the rotating shafts 601, limiting the lower end of the pin rod 5 and the insertion pipe 401 and preventing the pin rod 5 from coming out.
[0030] Working principle: When in use, a central steel wire rope 101 is arranged in the middle of the anti-corrosion steel wire rope 1.

The single-strand twisted steel wire bundle 2 includes a plurality of steel wires 201 twisted and connected to each other. An isolation sleeve 202 is fixedly connected together on the outer sides of the plurality of twisted and connected steel wires 201. The isolation sleeve 202 is used to isolate between the plurality of single-strand twisted steel wire bundles 2 to prevent mutual extrusion and wear between the plurality of single-strand twisted steel wire bundles 2. An anti-corrosion rubber layer 104 is fixedly connected to the outer side of the fiberglass mesh layer 103. A plurality of wear-resistant rubber strips 105 are fixedly connected in an annular array on the outer side of the anti-corrosion rubber layer 104. The wear-resistant rubber strips 105 and the anti-corrosion rubber layer 104 are fixedly connected by hot melt adhesive. The wear-resistant rubber strips 105 are used to improve the wear resistance of the entire anti-corrosion steel wire rope 1. The connection between two anti-corrosion steel wire ropes 1 is realized by inserting the insertion column 301 of the first connector 3 on one anti-corrosion steel wire rope 1 into the insertion tube 401 of the second connector 4 on the other anti-corrosion steel wire rope 1 and threadedly connecting and fixing through the external thread portion 302 and the internal thread portion 402. The upper end of the pin rod 5 extends out of the upper end of the second through hole 403 and is fixedly connected with a limit piece. The lower end of the pin rod 5 extends out of the lower end of the second through hole 403 and rectangular grooves 501 are arranged on both sides. After the insertion column 301 and the insertion tube 401 are fixedly connected, the pin rod 5 passes through the first through hole 303 and the second through hole 403 to limit the rotation of the insertion column 301 in the insertion tube 401 and improve the connection strength between the insertion column 301 and the insertion tube 401.
