Description

Reel hoist cable

Technical Field

The utility model relates to the technical field of cables, specifically a reel hoist cable.

Background

The port machine cable mainly comprises a drag chain power cable, a drag chain control cable, a drag chain communication cable, a drag order communication cable, a rolled cable and the like, and is mainly suitable for a port machinery drag chain system, a built-in drag chain is used, and the cable is subjected to repeated winding. The reel hanger cable is mainly used for reeling connecting lines, mobile equipment, cable conveyers and cable cars which require high mechanical stress, and vertical reel operation, and not only requires the cable to have good electrical property and mechanical property, but also requires the cable to have good properties of flexibility, tensile strength, wear resistance and the like, and particularly has high requirements on the flexibility and tensile strength of the cable;

traditional reel hoist cable generally adopts rubber material, and when the cable received tensile state under for a long time and used, the easy emergence fracture of the insulating sinle silk of cable, traditional rubber sheath simultaneously through tensile back repeatedly, mechanical properties can greatly reduced, in abominable service environment, the sheath can be ageing with higher speed, the sheath is ftractureed easily, cable life is shorter.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a reel hoist cable to when solving among the prior art cable and receiving tensile state under for a long time, the insulating sinle silk of cable breaks easily, and traditional rubber sheath is in through the tensile back that relapses simultaneously, and mechanical properties can greatly reduced, and in abominable service environment, the sheath can be ageing with higher speed, and the sheath is cracked easily, the shorter problem of cable life.

In order to achieve the above object, the utility model provides a following technical scheme: the reel hanger cable comprises a cable main body and a tensile rope, wherein the cable main body is twisted with the tensile rope, the twisting radian of the cable main body is larger than that of the tensile rope, and the outermost layer of the cable main body is wound with a braided cloth wrapping circle.

Preferably, a polyurethane outer sleeve is arranged inside the round-covered woven cloth, and an insulating sleeve is arranged inside the polyurethane outer sleeve.

Preferably, aramid fiber woven reinforcing bearing elements are arranged in the middle of the inner portion of the insulating sleeve, and cable cores are arranged between the aramid fiber woven reinforcing bearing elements and the insulating sleeve.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses well cable main part and tensile rope transposition, the transposition radian of cable main part is greater than the transposition radian of tensile rope, and when the cable main part of transposition and tensile rope used, the tensile rope replaced the cable main part bearing, was drawn, had guaranteed the cable main part to the greatest extent, avoided its damage because the pulling force was too big;

2. the utility model discloses set up the cloth of weaving encircleing, can protect the outside of polyurethane overcoat to receive the damage, also further assurance cable main body's tensile degree.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic end view of the cable main body of the present invention.

In the figure: 1. a cable body; 11. wrapping the round by weaving cloth; 12. a polyurethane jacket; 13. aramid woven reinforcing load bearing members; 14. a wire core; 15. an insulating sleeve; 2. a tensile strand.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a reel hanger cable includes a cable main body 1, and further includes a tensile cord 2, the cable main body 1 is twisted with the tensile cord 2, a twisting radian of the cable main body 1 is greater than a twisting radian of the tensile cord 2, when the twisted cable main body 1 and the tensile cord 2 are used, the tensile cord 2 replaces the cable main body 1 to bear and pull, so as to ensure the cable main body 1 to the maximum extent, and avoid the damage caused by an excessively large pulling force;

as shown in fig. 1, a woven cloth covered circle 11 is wound on the outermost layer of a cable body 1, a polyurethane outer sleeve 12 is arranged inside the woven cloth covered circle 11, an insulating sleeve 15 is arranged inside the polyurethane outer sleeve 12, an aramid woven reinforcing bearing element 13 is arranged in the middle of the inside of the insulating sleeve 15, a wire core 14 is arranged between the aramid woven reinforcing bearing element 13 and the insulating sleeve 15, the wire core 14 is used for conducting wires and transmitting signals, the strength and the tensile strength of the aramid woven reinforcing bearing element 13 and the cable body 1 can be enhanced, the cable body 1 is further prevented from being damaged, and the insulating sleeve 15 is used for insulating the wire core 14 and avoiding electric leakage;
