In a preferred embodiment of the present invention, two tearing grooves are respectively disposed on the upper and lower surfaces of the outer sheath, the two tearing grooves on the upper surface of the outer sheath are disposed in the central symmetry of the cross section of the outer sheath, and the two tearing grooves on the lower surface of the outer sheath are also disposed in the central symmetry of the cross section of the outer sheath.
In a preferred embodiment of the present invention, the bottom of each tearing groove is flat, and the groove edges at both sides are convex arc.
In a preferred embodiment of the present invention, each wire harness is formed by twisting six wires, and the six wires are uniformly distributed in the circumferential direction.
Since the technical scheme as above is adopted, the utility model discloses an hypervelocity retinue cable adopts five pencil and every pencil to adopt six wire transposition to form, has shortened the width of retinue cable like this, and it is less to occupy the well area, and oversheath width direction's both sides are the inclined plane through to the slope of circular arc direction slope between circular arc and the upper and lower surface of oversheath and the circular arc simultaneously and are connected, and the windage that gets up in the operation like this is littleer, is fit for the hypervelocity operation. In addition, the bottom of each tearing groove is flat, and the groove edges on the two sides are in a convex arc shape, so that the wind resistance is further reduced. Two steel wire ropes are positioned at the outermost ends of the left side and the right side of the outer sheath, so that the running stability of the traveling cable at the over-speed is improved.
The utility model discloses the biggest automatic height that hangs can reach 320m, and the biggest promotion height can reach 640m, and the maximum functioning speed can reach 10m/s, and weight 2.3 0.3kg/m is referred to the cable, and wire rope breaking force 37.1KN, 20 ℃ free bending diameter 600 ± 50 mm.
Drawings
Fig. 1 is a schematic cross-sectional view of the ultra-high speed traveling cable of the present invention.
Detailed Description
