Abstract

The utility model relates to a reel drag cable. The reel drag cable is designed mainly for solving the problem that the conventional reel drag cable is short in service life and high in price, and comprise a steel wire soft rope. A high strength nylon belt is wrapped on the outside of the steel wire soft rope, and a plurality of insulating wire cores surround the outer circumference of the steel wire soft rope on which the high strength nylon belt is wrapped. Each insulating wire core comprises a cable conductor formed by twisting copper wires, a polyester isolation strip is wrapped on the outside of each cable conductor, an insulating layer made of a flexible and high-strength ethylene propylene rubber is extruded on the outside of each polyester isolation strip, and a polyester belt is wrapped on the outsides of the insulating layers. Filling ropes are arranged between the high strength nylon belt and the insulating wire cores, the insulating wire cores and the steel wire soft rope on which the high strength nylon belt is wrapped are twisted into a cable, and then an inner pad layer is extruded on the outside of the cable; a nylon belt is wrapped on the outside of the inner pad layer, and an outer sheath is arranged on the outside of the nylon belt. The advantages of the utility model are that the reel drag cable is wear resistant, and is good in tensile strength, long in service life and low in cost.

Description

A kind of reel drag cable

Technical field:

The utility model relates to a kind of reel drag cable.

Background technology:

China's traffic of a port ranks first in the world, that bulk carrier harbour or container terminal all have tens large-sized gantry formula jack lifts in a row, these cranes need to move back and forth frequently, the power source that they move transmits by a flexible cable that also moves thereupon, flexible cable is wrapped in the reel of cable hank, the needs that reel moves by the crane folding and unfolding of constantly reeling pulls flexible cable, so this cable is called the reel drag cable, it is a kind of special cable that produces along with the harbour prosperity in the last few years, but due to the lower work in the open of this cable, working environment is poor, it is exposed to the sun and rain for a long time, particularly cable is constantly reeled and while pulling and ground friction, cause aging speed fast, useful life is short.Domestic this kind of cable generally only has about three months useful life, although from the useful life of external import, can reach more than a year, price is very expensive.

Summary of the invention:

Technical problem to be solved in the utility model is to provide a kind of long service life, the reel drag cable that cost is low.

above-mentioned purpose is achieved in that it comprises the steel wire tightrope of pull-off force greater than 800 ㎏, the steel wire tightrope is positioned at the center of whole cable, steel wire tightrope outside is surrounded with the high-strength nylon band, several insulated wire cores are centered around on the steel wire tightrope excircle that is surrounded with the high-strength nylon band, each insulated wire cores comprises by diameter being the stranded cable conductor that forms of thin copper wire of 0.20mm, each wrapped polyester isolation strip, cable conductor outside, each outside, polyester isolation strip is extruded with the insulating barrier of being made by the high strength ethylene-propylene rubber of softness, insulating barrier is surrounded with polyester belt outward, between high-strength nylon band and each insulated wire cores, gasket for packing is arranged, after each insulated wire cores twists together stranding with the steel wire tightrope that is surrounded with the high-strength nylon band, outside is extruded with inner cushion layer, the inner cushion layer outside is surrounded with nylon tape, there is the oversheath of being made by the high strength ethylene-propylene rubber of softness the nylon tape outside.

The utility model has the advantages that: wear-resisting, tensile strength is good, anti-bending, and long service life,, according to test, can use about 2 years, and cost is low.

Description of drawings:

Accompanying drawing 1 is cross-sectional structure schematic diagram of the present utility model.

Embodiment:

with reference to accompanying drawing, it comprises the steel wire tightrope 1 of pull-off force greater than 800 ㎏, the steel wire tightrope is positioned at the center of whole cable, steel wire tightrope outside is surrounded with high-strength nylon band 2, several insulated wire cores are centered around on the steel wire tightrope excircle that is surrounded with the high-strength nylon band, each insulated wire cores comprises by diameter being the stranded cable conductor that forms 3 of thin copper wire of 0.20mm, each wrapped polyester isolation strip 4, cable conductor outside, each outside, polyester isolation strip is extruded with the insulating barrier 5 of being made by the high strength ethylene-propylene rubber of softness, insulating barrier is surrounded with polyester belt 10 outward, between high-strength nylon band 2 and each insulated wire cores, gasket for packing 9 is arranged, after each insulated wire cores twists together stranding with the steel wire tightrope that is surrounded with the high-strength nylon band, outside is extruded with inner cushion layer 6, the inner cushion layer outside is surrounded with nylon tape 7, there is the oversheath 8 of being made by the high strength ethylene-propylene rubber of softness the nylon tape outside.
