Abstract
A dragging cable for an underground digger comprises a cable core, an inner sheath 9, an anti-torsion woven layer 10 and an outer sheath 11. The cable core is formed by twisting three power wire cores, three ground wire cores and a Y-shaped filling core. The lay ratio of the cable core is 8 to 11 times. The cable core is sequentially coated with the inner sheath 9, the anti-torsion woven layer 10 and the outer sheath 11 from inside to outside. The Y-shaped filling core is formed by a center monitoring wire core and a Y-shaped support 12. The center monitoring wire core is formed by a conductor B5 and an insulation layer B6. The center of the Y-shaped support 12 is provided with a through hole 12-1 for containing the center monitoring wire core and the Y-shaped support 12 is provided with three equally-divided vertex angles 12-2. The dragging cable can completely meet the requirement for use in various weather conditions, conductive performance and flexibility are good, the winding radius is small, electromagnetic immunity is high, the tensile strength of the wire cores is effectively improved, bending performance, monitoring performance and the stability of the cable structure are obviously enhanced, and service life is greatly prolonged.

The further technical scheme of the present invention is: power wire core is made up of conductor A, inner shield, insulating barrier A and metal/fiber braiding layer, and internal shield, insulating barrier A and metal/fiber braiding layer are coated on the outer surface of conductor from inside to outside successively.
The present invention further technical scheme is: wire core is made up of conductor C and insulating barrier C, is coated on the outer surface of conductor C with the insulating barrier C that semiconductive polyolefin elastomer makes.
The present invention further technical scheme is: Y shape is filled out core and is made up of center monitors core and Y shaped bracket, and center monitors core is arranged in the through hole at Y shaped bracket center;
Center monitors core is made up of conductor B and insulating barrier B, and insulating barrier B is coated on the outer surface of conductor B;
There is the through hole for holding center monitors core at the center of Y shaped bracket, and it has the drift angle of three decile distributions, have the circular arc indent for mutually embedding power wire core between adjacent two drift angles, the circular arc indent for mutually embedding wire core is arranged at the top of each drift angle; The thickness at each angle of Y shaped bracket is not less than 1.5mm.
The present invention as above designs owing to adopting, and compared with prior art, has following features:
1, the present invention adopts and has excellent fire-retardant, high strength, high-wearing feature, high anti-tear, high temperature resistant, low temperature resistant ozone, the black chlorinated polyethylene rubber of corrosion-resistant, oil resistant, weather, moisture proof, waterproof or neoprene and make oversheath, can meet the instructions for use of all kinds of weather conditions completely.
2, the present invention adopts the tinned copper wire of the stranded bunchy of multiply filament to make conductor, electric conductivity and softness good, winding radius is little.
3, the present invention adopts symmetrical three cores and metal/fibrage layer process, and electromagnetism strong interference immunity, the tension that effectively improve core drags ability.
4, the present invention adopts center monitors core and Y shape to fill out cored structure, makes the bending property of cable, monitors that the stability of performance and the construction of cable obviously strengthens.
5, the present invention adopt anti-twisting property and resistance to tension is good, with the good Polyester Yarns of rubber adhesion as antitorque braid, the tension of cable and bending property are strengthened greatly, and useful life extends greatly.
