Embodiment Construction

[0010] Such as figure 1 As shown, a flexible reinforced structure anti-drag rubber-sheathed flexible cable according to the present invention includes a cable core 1 located in the center of the cable. The cable core in this embodiment is formed by twisting four insulated wire cores. It can be combined by several insulated wire cores. The inner sheath 2 is extruded outside the cable core 1, and then the reinforcement rope 3 is evenly wound and stranded on the outer surface of the inner sheath to form a reinforcement layer, and then the outer sheath 4 is tightly extruded outside the reinforcement layer.

[0011] Such as figure 2 , the reinforcing rope 3 is an aramid yarn reinforcing rope, and its structure is to twist and twist several strands of aramid yarn 5 together, and then weave a layer of aramid yarn 6 on the outer surface of the twisted aramid yarn. The invention replaces the single sheath structure of the traditional cable, that is, after the rubber insulated wire c...

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...
