Abstract
The invention discloses a kind of power shovel vehicle cables, outer jointing jacket including cable core and outside cable core, the cable core includes strengthening core and four insulated wire cores for waiting cores, the center of four insulated wire cores for waiting cores is located on same circumference and adjacent two insulated wire cores are against each other, strengthening core is located among four insulated wire cores, insulated wire cores include conductor and the insulating layer being coated on outside conductor, strengthening core includes twisted stone dead wire and is coated on outside twisted stone dead wire to extrude rubber layer, one layer of glide band is externally provided with extruding rubber layer, glide band is abutted with the insulating layer of four insulated wire cores.The present invention is using the above scheme, reasonable in design, increases the tension creep resisting ability of cable, increases the sliding between insulated wire cores, insulated wire cores friction force is reduced, so as to improve cable service life.
Description
Technical field：
The present invention relates to a kind of power shovel vehicle cables.
Background technology：
The function mode of the Special electrics forklift cable such as iron ore, Gypsum Mine, gold mine as roll rope for drawing water from a well fetch water formula need repeat roll up
It puts, and stress is serious, operating environment is severe, therefore intensity to cable, to stretch rate, soft abrasion-resistant, anti-extrusion requirement quite stringent.
Due to being influenced by occupation mode and environment, the service life of existing domestic cable cannot meet the needs of client, scrap frequently,
Production cost increases.
Common power shovel vehicle cable is as shown in Figure 1, generally 3+1 cores or 4 grade cores soft rubber cables, the effect of central filler object
Also only play the role of buffering extraneous extruding force, usually rubber adhesive tape.The filling of 4 grade cores cables of normal production design is straight
Diameter is about 0.42 times of insulated wire cores diameter.
Invention content：
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of power shovel vehicle cables, it is reasonable in design, improve
The intensity of cable stretches rate, soft abrasion-resistant degree and anti-extrusion ability, increases the sliding between insulated wire cores, reduces insulated wire cores
Friction force extends the service life of cable, solves problems of the prior art.
The used to solve above-mentioned technical problem technical solution of the present invention is：
A kind of power shovel vehicle cable, the outer jointing jacket including cable core and outside cable core, the cable core include strengthening core and
Four wait cores insulated wire cores, four wait cores insulated wire cores center be located on same circumference and adjacent two insulated wire cores that
This is abutted, and strengthening core is located among four insulated wire cores, and insulated wire cores include conductor and the insulating layer being coated on outside conductor, strengthen
Core includes twisted stone dead wire and is coated on outside twisted stone dead wire to extrude rubber layer, and one layer of sliding is externally provided with extruding rubber layer
Band, glide band are abutted with the insulating layer of four insulated wire cores.
Extrude a diameter of insulated wire cores diameter of rubber layer 0.5-0.6 times.
Bituminous coating is equipped on the outside of outer jointing jacket.
The present invention is using the above scheme, reasonable in design, increases the tension creep resisting ability of cable, increases insulated wire
Sliding between core reduces insulated wire cores friction force, so as to improve cable service life.
Description of the drawings：
Fig. 1 is the structure diagram of traditional cable.
Fig. 2 is the structure diagram of the present invention.
In figure, 1, outer jointing jacket, 2, conductor, 3, insulating layer, 4, twisted stone dead wire, 5, extrude rubber layer, 6, glide band, 7,
Bituminous coating.
Specific embodiment：
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this hair
It is bright to be described in detail.
As shown in Fig. 2, a kind of power shovel vehicle cable, the outer jointing jacket 1 including cable core and outside cable core, the cable core packet
Include the insulated wire cores that strengthening core and four wait cores, the center of four insulated wire cores for waiting cores is located on same circumference and adjacent two
Insulated wire cores are against each other, and strengthening core is located among four insulated wire cores, and insulated wire cores include conductor 2 and are coated on outside conductor 2
Insulating layer 3, strengthening core includes twisted stone dead wire 4 and is coated on outside twisted stone dead wire 4 to extrude rubber layer 5, is extruding rubber
Cortex 5 is externally provided with one layer of glide band 6, and glide band 6 is abutted with the insulating layer 3 of four insulated wire cores.
Extrude a diameter of insulated wire cores diameter of rubber layer 0.5-0.6 times, more than 0.42 times of traditional design.It is logical
Crossing the mode of increase filler diameter makes filler stress, so as to reduce the stress of insulated wire cores.
Bituminous coating 7 is equipped in 1 outside of outer jointing jacket, there is anti-corrosion function.
It substitutes traditional rubber adhesive tape using the cored structure of strengthening of twisted stone dead wire+extrude rubber layer and fills, increase electricity
The tension of cable, anti-extrusion ability increase sliding between insulated wire cores extruding the glide band 6 that is set outside rubber layer 5, alleviate
Insulated wire cores friction avoids since frictional resistance brings the generation of fatigue fracture phenomenon, improves cable life.
Above-mentioned specific embodiment cannot function as limiting the scope of the invention, for the technology people of the art
For member, any alternate modification or transformation made to embodiment of the present invention are all fallen in protection scope of the present invention.
Part is not described in detail by the present invention, is the known technology of those skilled in the art of the present technique.
