Description

A kind of Novel pre-hinged damper

Technical field

This utility model relates to damper, is specifically related to a kind of Novel pre-hinged damper.

Background technology

The impact of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, can make power circuit Produce vibration or wave.The frequency of generation vibration is higher but amplitude is the least, in this case, Vibration can make overhead power line repeatedly by stubborn folding at suspension point, causes fatigue of materials, finally can Cause the generation of the disconnected accident such as stock, broken string；The frequency waved is the lowest, and amplitude is very big, very Easily cause alternate flashover, cause line tripping, have a power failure or the major accidents such as wire of burning.Anti- Vibration hammer be one iron leg rod, owing to it is carried additionally at circuit tower bar suspension point, can be used to absorb or Damping vibration energy, changes circuit wobble frequency, it is possible to prevent the vibration of circuit or wave.

Traditional damper uses bolt to fix, and during installation, workmen must be provided with torque wrench, Do not possess these instruments once when construction team, installation process will occur moment of torsion excessive or turn round The situation that square is too small.Moment of torsion is crossed conference and is caused the damage of wire or bolt；Moment of torsion is too small, then prevent Grip between vibration hammer and wire can not be up to standard.Even if using torque wrench to install, damper With the grip between wire has reached requirement, but it is as shaking of wire and damper during circuit runs Dynamic, the stress of wire and bolt can taper into, and the grip between wire and damper reduces, meeting Causing loosening of shockproof hammer thread clip, thus cause damper to deviate initial makeup location, this kind partially Happen occasionally on the circuit put into operation from phenomenon.

The shortcoming that Pre-Cutter-Type Anti-Vibration Hammer overcomes above-described bolt fastening damper.Install Pre-Cutter-Type Anti-Vibration Hammer need not any instrument, free-hand can complete, quick and easy for installation, construction With low cost.Grip between the preformed armor rods of damper and wire is dispersed in the length of 30-80cm On degree region, it is to avoid the stress of wire is excessively concentrated.The aluminum Baogang material of function admirable is installed Preformed armor rods ensure that grip continual and steady between preformed armor rods and wire.It is demonstrated experimentally that experience 200,000,000 After secondary vibration, damper is relative to wire without any displacement, and conductive line surfaces is without any damage Wound, damper itself is intact.

At notification number CN201927975U, date of declaration is the practical new of on August 10th, 2011 Type patent discloses a kind of Pre-Cutter-Type Anti-Vibration Hammer, including hammer body, it is characterized in that two symmetrical Hammer body is connected on wire clamp by steel strand wires, and wire clamp top is hook-shaped, wire clamp top and electric wire Contact portion arranges anticorrosion rubber blanket, arranges preformed armor rods simultaneously.This Pre-Cutter-Type Anti-Vibration Hammer exists Construction uses preformed armor rods install, it is not necessary to installation tool, improve working security, and energy Keep constant moment, slip phenomenon will not occur.But this Pre-Cutter-Type Anti-Vibration Hammer uses extension The wire clamp of hook-type, it is impossible to be fixed on wire to firm stable, it is easy to depart from wire；Single spiral shell The preformed armor rods of rotation structure is compared to double-stranded preformed armor rods, and its stability and fastness ratio are double Spiral preformed armor rods is very different；When the situation of accumulated snow or icing occurs on damper, if Can not remove ice and snow the most in time, the vibrationproof performance of damper can be substantially reduced, meanwhile, long-pending Water also can make the key position of damper get rusty, and can reduce the vibrationproof performance of damper equally.

Utility model content

(1) solve the technical problem that

For the disadvantages mentioned above existing for prior art, this utility model provides a kind of novel pre- Strand formula damper, it is possible to effectively overcome and be easily separated from wire, stability existing for prior art Poor with fastness and lack the defects such as snow melt water removal body.

(2) technical scheme

For realizing object above, this utility model is achieved by the following technical programs:

A kind of Novel pre-hinged damper, including wire clamp, described wire clamp top is provided with chuck, institute Being fixed with preformed armor rods in stating chuck, described preformed armor rods is Double-spiral, fixing bottom described wire clamp Having steel strand wires, described steel strand wires two ends to be fixed with tup, described Novel pre-hinged damper also sets There is snow melt water removal body.

Preferably, described snow melt water removal body includes the photothermal deformation being located at described steel strand wires both sides Device and carbon fiber heating line.

Preferably, it is provided with damping rubber pad inside described chuck.

Preferably, cave inward in the middle part of described chuck.

Preferably, described chuck top is provided with the string holes coordinated with preformed armor rods.

Preferably, described tup is tuning-fork type tup.

(3) beneficial effect

Compared with prior art, a kind of Novel pre-hinged damper provided by the utility model is adopted With chuck, and make to cave inward in the middle part of chuck, coordinate Double helix preformed armor rods, it is possible to make whole anti- It is clipped on wire to vibration hammer firm stable, will not depart from from wire；Snow melt water removal body can Remove the accumulated snow on damper or hydrops in time, be effectively improved damper preventing when sleety weather Shake performance.
