The above technical scheme is adopted in the utility model, structural design is reasonable, has increased the anti creep ability of tensile of cable, increases sliding between insulation core, has reduced insulation core rubbing action power to improve cable life.

Description

A kind of power shovel car cable

Technical field:

This utility model relates to a kind of power shovel car cable.

Background technology:

The function mode of the Special electric forklift cables such as iron mine, Gypsum Mine, gold mine needs to repeat volume put such as the wheel rope for drawing water from a well formula of fetching water, and stress is serious, and working environment is severe, thus to the intensity of cable, to stretch rate, soft abrasion-resistant, anti-extrusion requirement quite strict. Due to the impact by occupation mode and environment, the demand that client can not be met service life of existing domestic cable, to scrap frequently, production cost strengthens.

Common power shovel car cable is as it is shown in figure 1, be generally the core rubber sleeve flexible cables such as 3+1 core or 4, and the effect of central filler thing also simply serves the effect of the extraneous extruding force of buffering, is generally rubber adhesive tape. The normal diameter of filling producing design 4 core cables such as grade is about 0.42 times of insulated wire cores diameter.

Utility model content:

This utility model is in order to make up the deficiencies in the prior art, provide a kind of power shovel car cable, its reasonable in design, improve the intensity of cable, stretch rate, soft abrasion-resistant degree and anti-extrusion ability, increase the sliding between insulated wire cores, reduce insulated wire cores friction force, extend the service life of cable, solve problems of the prior art.

This utility model be the technical scheme is that by the above-mentioned technical problem of solution

A kind of power shovel car cable; including cable core and be located at the outer jointing jacket outside cable core; described cable core includes the insulated wire cores of the cores such as strengthening core and four; the insulated wire cores of four cores such as grade is centrally located on same circumference and adjacent two insulated wire cores are against each other; strengthening core is positioned in the middle of four insulated wire cores; insulated wire cores includes conductor and the insulating barrier being coated on outside conductor; strengthening core includes stranded stone dead wire and is coated on and extrudes rubber layer outside stranded stone dead wire; being externally provided with one layer of glide band extruding rubber layer, the insulating barrier of glide band and four insulated wire cores abuts.

Described extrude that rubber layer diameter is insulated wire cores diameter 0.5-0.6 times.

Bituminous coating it is provided with outside outer jointing jacket.

This utility model adopts such scheme, reasonable in design, adds the tension creep resisting ability of cable, increases the sliding between insulated wire cores, reduces insulated wire cores friction force, thus improving cable service life.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of traditional cable.

Fig. 2 is structural representation of the present utility model.

In figure, 1, outer jointing jacket, 2, conductor, 3, insulating barrier, 4, stranded stone dead wire, 5, extrude rubber layer, 6, glide band, 7, bituminous coating.

Detailed description of the invention:

For knowing the technical characterstic that this programme is described, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Figure 2, a kind of power shovel car cable, including cable core and be located at the outer jointing jacket 1 outside cable core, described cable core includes the insulated wire cores of the cores such as strengthening core and four, the insulated wire cores of four cores such as grade is centrally located on same circumference and adjacent two insulated wire cores are against each other, strengthening core is positioned in the middle of four insulated wire cores, insulated wire cores includes conductor 2 and the insulating barrier 3 being coated on outside conductor 2, strengthening core includes stranded stone dead wire 4 and is coated on and extrudes rubber layer 5 outside stranded stone dead wire 4, it is externally provided with one layer of glide band 6 extruding rubber layer 5, glide band 6 abuts with the insulating barrier 3 of four insulated wire cores.

Described extrude that rubber layer diameter is insulated wire cores diameter 0.5-0.6 times, more than 0.42 times of traditional design. Implant stress is made, thus reducing the stress of insulated wire cores by increasing the mode of implant diameter.

Outside outer jointing jacket 1, it is provided with bituminous coating 7, there is anti-corrosion function.

The strengthening core structure adopting stranded stone dead wire+extrude rubber layer substitutes traditional rubber adhesive tape and fills, add the tension of cable, anti-extrusion ability, extruding the sliding that the outer glide band 6 arranged of rubber layer 5 adds between insulated wire cores, alleviate insulated wire cores friction, avoid owing to frictional resistance brings the generation of fatigue fracture phenomenon, improve cable life.

Above-mentioned detailed description of the invention cannot function as the restriction to this utility model protection domain, and for those skilled in the art, any alternate modification made to this utility model embodiment or conversion all fall within protection domain of the present utility model.

This utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
