Description

High-flexibility towline cable

Technical Field

The utility model belongs to cable preparation field, a high flexibility tow chain cable.

Background

In the occasion that the equipment unit needs to move back and forth, in order to prevent the cable from tangling, abrasion, pulling off, hanging and scattering, the cable is often put into a cable drag chain to form protection for the cable, and the cable can also move back and forth along with the drag chain. The drag chain cable needs round trip movement, bending, dragging when using, causes the cable core that breaks easily, especially domestic like product at present, and most cabling structure is all sinle silk stranding together, because the sinle silk is more, because crooked removal produces frictional force between the sinle silk, causes sinle silk quality problem easily, reduces life.

Chinese patent: 105575510B discloses a novel drag chain cable at 2018-07-03, which comprises a wire core and a drag chain ring; the drag chain ring is in a flat ring cylinder shape, bar magnets extending along the axial direction of the drag chain ring are uniformly distributed in the circumferential direction of the drag chain ring, and the arrangement directions of magnetic poles of the bar magnets are consistent; translation wheels are further mounted on the outer ring surface of the towing chain ring at equal intervals, and the wheel surface of each translation wheel passes through the axis of the towing chain ring; annular grains are engraved on the inner ring surface of the drag chain ring; the cable has simple structure and is convenient to store and use; extension, translation that can be swift can realize the side simultaneously and move, can show improvement work efficiency. But still have the cabling structure for all sinle silks cabling transposition together, because the sinle silk is more, because crooked removal produces frictional force between the sinle silk, causes sinle silk quality problem easily, reduces life.

SUMMERY OF THE UTILITY MODEL

To the traditional cable structure that still exists that prior art exists for all sinle silks cable stranding together, because the sinle silk is more, because crooked removal produces frictional force between the sinle silk, causes sinle silk quality problems easily, reduces life's technical problem, the utility model provides a high flexibility tow chain cable.

In order to solve the technical problem, the utility model discloses the technical scheme who takes does: the utility model provides a high flexibility towline cable, is including strengthening sinle silk and a plurality of insulation core, and every insulation core all includes the conductor of the same quantity, the conductor is the thin soft copper wire of national standard sixth class, and the outside of every conductor is all crowded package and is had soft level soft polyvinyl chloride insulating layer, and the conductor of the same quantity is wrapped into insulation core by the band, strengthen sinle silk and insulation core and together wrap up in the outer band layer, the central point of towline cable puts and places and strengthen the sinle silk, insulation core evenly distributed is around strengthening the sinle silk, all insulation core all with strengthen the sinle silk butt, the outside package on outer band layer is equipped with polyurethane elastomer sheath, the external diameter of strengthening the sinle silk is greater than insulation core's external diameter. The conductor adopts the sixth type conductor specified by national standards, and is softer and has more excellent bending performance. The insulating layer adopts soft level soft polyvinyl chloride insulating material, and this material not only has good insulating nature, stability, still has fine compliance, can guarantee that the insulating layer can not the problem when the cable is crooked. The insulated wire cores are firstly cabled into small wire cores and then are wrapped to enable the small unit wire cores to be more stable. The center is placed and is strengthened the sinle silk during the stranding, strengthens cable atress performance, and other little stranding sinle silks are around strengthening the sinle silk stranding in proper order, and stable in structure between the sinle silk in the little stranding not only like this to make between whole little unit and other little units structure when the cable is crooked more stable, be difficult to take place the quality problem. The outer jacket is made of a polyurethane elastomer sheath material, the material has good flexibility and wear resistance and high tensile strength, the cable can be protected from being damaged by external force in dragging movement, the quality problem caused by the dragging external force is reduced, and the service life of the cable is greatly prolonged.

Preferably, all adjacent insulated wire cores abut against each other.

Preferably, the inner gap of the outer wrapping belt layer of the high-flexibility drag chain cable is filled with the polypropylene filling rope during cabling

Preferably, the outer wrapping belt layer of the high-flexibility towline cable is a thin non-woven fabric wrapping belt. Adopt thin non-woven fabrics band to overlap the package in order to increase the stability of cable structure and the circularity of cable, because the band thickness is thin (0.07 mm), the feel is very soft to the compliance that has also increased the cable.

Preferably, the thickness of the thin non-woven fabric wrapping tape is less than 0.07 mm.

The utility model discloses a substantive effect is: the conductor adopts the sixth type conductor specified by national standards, and is softer and has more excellent bending performance. The insulating layer adopts soft level soft polyvinyl chloride insulating material, and this material not only has good insulating nature, stability, still has fine compliance, can guarantee that the insulating layer can not the problem when the cable is crooked. The insulated wire cores are firstly cabled into small wire cores and then are wrapped to enable the small unit wire cores to be more stable. The center is placed and is strengthened the sinle silk during the stranding, strengthens cable atress performance, and other little stranding sinle silks are around strengthening the sinle silk stranding in proper order, and stable in structure between the sinle silk in the little stranding not only like this to make between whole little unit and other little units structure when the cable is crooked more stable, be difficult to take place the quality problem. The outer jacket is made of a polyurethane elastomer sheath material, the material has good flexibility and wear resistance and high tensile strength, the cable can be protected from being damaged by external force in dragging movement, the quality problem caused by the dragging external force is reduced, and the service life of the cable is greatly prolonged.
