A flexible reinforced structure anti-drag rubber sheath flexible cable

Abstract

The invention discloses an anti-drag rubber-sheathed soft cable with a flexible reinforced structure, which comprises a cable core located at the center of the cable, and an inner sheath is extruded outside the cable core, and the outer surface of the inner sheath is reinforced by uniform winding and twisting of a reinforcing rope. layer, and then tightly extrude the outer sheath on the reinforcement layer. The above-mentioned reinforcing rope adopts aramid yarn reinforcing rope, and the aramid yarn reinforcing rope includes several strands of aramid yarn twisted together in the middle, and then a layer of aramid yarn is woven on the outer surface of the twisted aramid yarn . The invention adopts high-strength aramid yarn reinforcement material, which improves the tensile strength and is easy to process in the subsequent process; compared with the metal reinforcement layer, it does not need large-scale steel belt and steel wire armoring machines, which is convenient for workers to operate and reduces energy consumption. ; The bending and dragging performance of the cable is improved, the service life of the cable is extended, and the economic benefit is improved.

Description

[0001] technical field [0002] The invention relates to a wire and cable, in particular to a drag-resistant rubber-sheathed soft cable with a flexible reinforced structure. Background technique [0003] The existing cable reinforcement structure usually adopts steel belt wrapping reinforcement, steel wire winding and twisting reinforcement, steel wire braiding reinforcement, etc., that is, a layer of inner sheath is extruded after the cable insulation core is twisted, and the surface of the inner sheath is made of steel belt. , steel wire and other metal materials are armored and reinforced, and then a layer of outer sheath is extruded. Although metal reinforcement materials such as steel strips and steel wires improve the tensile strength and drag performance of the cable, they also affect the bending and winding performance of the cable during laying and use. During the process, the flexural performance is greatly reduced, and the long-term normal use of the cable cannot...

Problems solved by technology

Although metal reinforcement materials such as steel strips and steel wires improve the tensile strength and drag performance of the cable, they also affect the bending and winding performance of the cable during laying and use. During the process, the flexural performance is greatly reduced, and the long-term normal use of the cable cannot be guaranteed
