Summary of the invention
The purpose of this utility model is to provide a kind of one with breathing out sheath not from vibration damping cable, should be from its outer sheath good endurance of breathing out of vibration damping cable, and self has vibration-damping function, can improve the resist the elements impact of exciting of cable, improve the anti-fatigue life of cable body.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of from vibration damping cable, comprise cable body and be positioned at not sheath of the outer field Kazakhstan of cable body, it is characterized in that: not between sheath, have separation layer at cable body and in the outer field Kazakhstan of cable body, described separation layer or damping rubber or viscoelastic body or slow coagulated material or existing damping rubber are added with again the mixed structure body of viscoelastic body or slow coagulated material, separation layer or be directly distributed in whole rope length, or by being distributed on cable in the locating slot fixed point of breathing out not jacket inner wall setting.
Its further technical scheme is: being arranged on and breathing out the not damping rubber piece of jacket inner wall is semicircular structure, and its back is established a boss, and this boss coordinates installation with locating slot.
Described viscoelastic body is a kind of macromolecule polymer material simultaneously with some viscous liquid and elastic solid (Hookean body) characteristic; Comprise viscoplasticity rubber, viscoplasticity polyurethane, viscoplasticity propylene fat, viscoplasticity asphalt mixture, viscoplasticity latex mixture or viscoplasticity epoxy resin composition.
Described slow coagulated material is that a kind of original state is stream plastomer, can become thereafter the material of the solid with certain Rigidity and strength, as slow setting knot concrete.
Its again further technical scheme be: be not in described Kazakhstan that point-like distributes for how much or random distribution has multiple pits on the external surface of sheath, the shape of cross section of pit is rectangle, trapezoidal, semicircle, half elliptic, triangle or other arbitrary polygons, and the spacing between each pit equates or be unequal.
Its again further technical scheme or: in described Kazakhstan, not the external surface of sheath is provided with double helix muscle or is wound with double helix muscle.
Owing to adopting technique scheme, the one of the utility model has rain wind induced vibration is had to good inhibition from vibration damping cable, has improved the beneficial effect in the application life of cable:
First, the utility model is filled separation layer 2 breathing out not gap between jacket inner wall and cable, described separation layer comprises that damping rubber or viscoelastic body separation layer or slow coagulated material or existing damping rubber are added with again the mixed structure body of viscoelastic body or slow coagulated material, make cable self have vibration-damping function.
Secondly, by the not sheath face of breathing out, spiral bar and pit being set, make current deflection, prevent that the water small stream on cable body surface is along rotational vibration, thereby reach the object of vibration damping, make to breathe out the not function of the anti-rain wind induced vibration of sheath tool; By the mode of field-winding spiral bar, make to breathe out the not structure of sheath and have more stability simultaneously.
Below, in conjunction with the accompanying drawings and embodiments a kind of technical characterictic from vibration damping cable of the utility model is further described.
