Abstract
The utility model discloses a metal anti-vibrating hammer for an ADSS optical cable, particularly an anti-vibrating device. The utility model comprises two metal hammer heads, an elastic steel stranded wire and a metal cable support, wherein the two metal hammer heads which present half S shapes are respectively fixed to both ends of the elastic steel stranded wire; the steel stranded wire is permanently fixed on the metal cable support; the plane of one side of the metal cable support approaching to an optical cable is provided with a hole; the weight and the volumes of the two metal hammer heads are different, with different bending degrees of the half S shapes and different distances from the metal cable support. The utility model can generate more than four resonant frequencies and can effectively decrease the oscillation amplitude of a line. Additionally, the use of a fixed preformed stranded yarn decreases the damage to the optical cable and the break of the optical cable in the course of using the anti-vibrating hammer. The utility model is suitable for preventing vibration of an ADSS optical cable.
Description
Technical field:
The utility model relates to a kind of vibration abatement, particularly a kind of metal stockbridge damper that is used for ADSS (all dielectric self-supporting) optical cable.
Background technology:
Built on stilts ADSS optical cable in use can produce vibrations owing to be subjected to wind action, and in long-term vibrations, the fixing position of ADSS optical cable and shaft tower is caused damage owing to constantly impacting, even fracture.In order to reduce and prevent to shake the generation of the damage that causes, one of them solution is to install stockbridge damper additional from one meter to two meters of bearing.According to overground cable vibration frequency operational formula, the gentle breeze vibration frequency that thinner aerial cable causes is higher, and scope is bigger.In practical operation, aerial condutor typically has a diameter from 16 to 26 millimeters, and the ADSS optic cable diameter is generally 10 to 14 millimeters, so thinner comparatively speaking ADSS optical cable, the higher scope of the frequency of vibrations is bigger.The thick relatively cable of the cable that physical features is tiny reason such as easy fracture more in addition, the relative aerial condutor of ADSS optical cable is easy fracture more.And the stockbridge damper that uses has at present been copied the stockbridge damper of special use on the power transmission line mostly mechanically, and its structure generally is to be made of two metal tups, Elastic Steel twisted wire, metal cables holder.Two problems have in use appearred: the one, and this class lead stockbridge damper generally can only produce few several harmonic shock frequency, can not better cover the vibration frequency scope of various circuits in the reality thus, reduces vibrations.The 2nd and the line place of ADSS optical cable adopt the mode of wire clamp or hook and screw or rivet to fix, this rigid fixation cause not little damage still can in the vibrations process original just tiny relatively ADSS optical cable, even caused fracture.
Summary of the invention:
The practical problems good inadequately at shockproof effect in traditional stockbridge damper use, that the ADSS optical cable ruptures easily, the utility model improves traditional stockbridge damper, makes it better to reduce the damage of vibrating, at utmost reducing the ADSS optical cable.
The technical solution of the utility model is as follows: this metal stockbridge damper that is used for the ADSS optical cable comprises two metal tups, Elastic Steel twisted wire, metal cables holder, described two metal tups are half serpentine, be separately fixed at the two ends of Elastic Steel twisted wire, the Elastic Steel twisted wire is fixed in the metal cables holder, porose on the plane of a side of close optical cable in the metal cables holder, the weight and volume difference of described two metal tups, the degree of crook of its half serpentine is inequality, and is inequality from metal cables holder distance.This stockbridge damper overall weight is not more than 1.2 kilograms.The material of its metal tup can be steel, aluminium or alloy aluminum, also can be other metal material, and its manufacturing process can be casting, forging and pressing.Method with cold weld or thermo-compressed between Elastic Steel twisted wire and tup or the metal cables carriage is connected, and also can be material adhesive.
The metal tup that volume and weight is bigger in the described metal tup is far away from the cable holder, and little metal tup is nearer from the cable holder.
Half serpentine degree of crook of the big metal tup of volume and weight is little in the described metal tup, and half serpentine degree of crook of little metal tup is big.
Described two metal tups lay respectively at the both sides on Elastic Steel twisted wire and plane, optical cable place.
The hole is at least two in the described cable holder, and its shape can be round, also can be oval.
Described stockbridge damper comprises that also stockbridge damper also comprises the hole passed in the described metal cables holder and the fixedly preformed armor rods on the ADSS optical cable.
Described stockbridge damper can be equipped with stockbridge damper and protect lines and be electrically connected preformed armor rods.
Described preformed armor rods is the wire coils of band screw pitch and screw diameter, and its material can be the suitable aluminium alloy single line of diameter, aluminium Baogang single line or other metal single lines; Its length is not stoped, and decides as required.
The beneficial effects of the utility model are:
1. owing to volume, weight, shape, the position difference of two metal tups, can produce at least four resonance frequencies, thereby can reduce generation of vibration better.
With ADSS optical cable junction owing to used preformed armor rods, adopt flexible fixation, can at utmost reduce the generation of ADSS optical cable damage.
3. because hammer body is the smooth flow linear shape of half " S ", also effectively reduced the generation of " corona ".

Fig. 2 is the vertical view of structure shown in Figure 1
Fig. 3 is that the A-A of structure shown in Figure 1 cuts open and shows
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As seen from Figure 1: the utility model ADSS optical cable uses the metal stockbridge damper by big hammer body 1 and hand hammer body 2, Elastic Steel twisted wire 3, metal cables holder 4 and around ADSS optical cable 6 fixing preformed 5 compositions, described two metal tups are half serpentine, be separately fixed at the two ends of Elastic Steel twisted wire 3, Elastic Steel twisted wire 3 is permanently affixed in the metal cables holder 4, and three preformed armor rodses perforation 7 are arranged on the plane of a side of close optical cable 6 in the metal cables holder 4.This perforation is circular.Metal tup 1,2 is half serpentine and smooth outer surface is streamlined.Big hammer body 1 relative hand hammer body 2 volume and weights are all bigger.Big hammer body 1 is far away from metal cables holder 4, and hand hammer body 2 is nearer from metal cables holder 4.Half serpentine degree of crook of big metal tup 1 is little, and half serpentine degree of crook of little metal tup 2 is big.Size hammer body 1,2 all is permanently affixed on the Elastic Steel twisted wire 3.Two metal tups 1,2 lay respectively at the both sides on Elastic Steel twisted wire and plane, optical cable place.In concrete operations, earlier hold ADSS optical cable 6 with metal cables holder 4, pass preformed armor rods with fixing preformed armor rods 5 and bore a hole 7, more fixing preformed armor rods 5 is fixed in ADSS optical cable 6 and metal cables holder 4.The utility model metal stockbridge damper overall weight is no more than 1.2 kilograms.
