AI Technical Summary
When steel wire ropes are in use, the gap between the rope core and the strands increases, leading to a decrease in strength and even wire breakage, due to the lack of an effective tensile connection design.
The structure adopts an inner steel wire core, a protective rubber layer, a fourth steel wire mesh, and stranded steel wires. It combines the third steel wire mesh, rubber friction layer, first and second textile mesh, and first and second steel wire mesh in the inner connecting part. The connection stability is increased by bonding the rubber layer and the alternately distributed connecting plates, and the overall structure is enhanced by the spiral twisting of the outer strands.
It effectively prevents the gap between the rope core and the stranded wire from widening, increases the structural strength and tensile strength of the rope core, avoids loosening and wear, and improves the durability of the mechanical drive rope.
