Abstract

The utility model discloses a buggy ladle cable. A conductor and a tension element are intertwisted; the intertwisted conductor and tension element are wrapped by an insulating layer to form an insulation wire core; the outside of the insulation cable core is waved by a glass fiber layer to form a wire core; a plurality of wire cores are intertwisted to form a cable core; the center gap of the cable core is filled with a rubber strip; the cable core is covered by a nylon braiding layer which is covered by a sheath layer; the sheath layer is covered by a thermal insulation layer; a splash-proof layer is arranged outside the thermal insulation layer. The buggy ladle cable has a simple structure, is high temperature resistant and splashproof and possesses soft, frequent bending and winding resistant and tensile performances.

Description

A kind of ladle vehicular cable

Technical field

The utility model belongs to the electric wire field, is specifically related to a kind of ladle vehicular cable.

Background technology

The operational environment of buggy ladle is quite abominable and harsh, and the cable that at first is used for buggy ladle almost all is to work under hot environment, is positioned at the buggy ladle joint and also is subjected to splashing of molten steel for a long time and burns.Secondly the buggy ladle cable needs frequent mobile at work, and the cable of buggy ladle need be wound on the reel, movement with buggy ladle, this harvests line to there unwrapping wire again through being everlasting, the situation that often has cable core to be broken takes place, at this moment change with regard to whole cable of needs, both caused waste, incured loss through delay normal working hours again.For preventing molten steel, cable burns, not only need sheath material having resistance to elevated temperatures also requires cable that antispray layer is arranged, simultaneously in order to prevent cable beating under frequent bending, coiling, the extended state common mechanical damages such as core of turning round, ftracture, break, the buggy ladle cable need have softness to need that also enough mechanical performances are arranged, because cable requires the useful life of soft and enough intensity and cable closely bound up under mobile status.

The utility model content

For overcoming above-mentioned deficiency, the utility model purpose provides a kind of high temperature resistant, splashproof that possesses, and the hired car cable of the performance of soft, anti-frequent bending and coiling, tension.

Scheme of the present utility model is as follows: a kind of ladle vehicular cable, conductor and aramid fiber tensile elements are stranded, extruded insulation layer after stranded constitutes insulated wire cores, the outer braided glass fibre layer of described insulated wire cores constitutes core, many cores are twisted into cable core, and described cable core center gap place doses unvulcanized rubber bar; Described cable core coats the knit nylon layer outward, and described knit nylon layer coats the restrictive coating of fibrage outward, and described restrictive coating coats the asbestos cloth thermal insulation layer outward, and described thermal insulation layer arranges the nickel alloy wire antispray layer outward.

The beneficial effects of the utility model:

1, the aramid fiber tensile elements is adopted at the conductor center, its tensile strength be same external diameter steel wire 5-8 doubly, can, enough satisfy flexibility and the mechanicalness requirement of cable in laying.

2, insulating barrier has woven one deck glass fiber outward; can play mechanical protection to insulation, also play heat-blocking action simultaneously, stranding cable core center adopts unvulcanized rubber bar to fill; adopt unvulcanized rubber bar to fill, that can fill in the cable core center clearance is very closely knit.

3, cable core adopts fibrage outward, and protective cover material can directly be clamp-oned in the gap of cable core, makes the construction of cable more stable, can allow sheath become as a whole with cable core simultaneously, improves the intensity of cable; The centre has the sheath of fibrage, can improve the mechanical strength of sheath; The outer wrapped one deck asbestos cloth of sheath can play heat-blocking action; Asbestos cloth has woven one deck nickel alloy wire outward, can prevent the burn sheath of cable of the slag that splashes.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

A kind of ladle vehicular cable, conductor 2 and aramid fiber tensile elements 1 are stranded, and the extruded insulation layer 3 after stranded constitutes insulated wire cores, and the outer braided glass fibre layer 4 of described insulated wire cores constitutes cores, many cores are twisted into cable core, and described cable core center gap place doses unvulcanized rubber bar 5; Described cable core coats knit nylon layer 6 outward, the described knit nylon layer 6 outer restrictive coating 7 that coats fibrage, the described restrictive coating 7 outer asbestos cloth thermal insulation layers 8 that coat, the described thermal insulation layer 8 outer nickel alloy wire antispray layers 9 that arrange.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.

Claims

1. ladle vehicular cable, it is characterized in that conductor and aramid fiber tensile elements are stranded, extruded insulation layer after stranded constitutes insulated wire cores, the outer braided glass fibre layer of described insulated wire cores constitutes core, many cores are twisted into cable core, and described cable core center gap place doses unvulcanized rubber bar; Described cable core coats the knit nylon layer outward, and described knit nylon layer coats the restrictive coating of fibrage outward, and described restrictive coating coats the asbestos cloth thermal insulation layer outward, and described thermal insulation layer arranges the nickel alloy wire antispray layer outward.
