Abstract

Disclosed is a vibration-proof hammer that comprises line clamp using two half circles structure; the outline of line clamp is circular and has hexagonal holes in which having left-handed anti-slip waves; lower end of the line clamp is die cast in the middle of steel strand and half sphere bolt goes through line clamp and get bound with spiral tooth anti-loose stop ring and nuts; the steel strand is die cast with the hammer body; when being elbow-fist type, the two hammer locate on 45-60 degree position. The invention has the advantages of low discharge from corona, low electromagnetic energy loss with the circular outline of the line clamp.

Description

Energy-saving vibration prevention hammer

Technical field

The present invention relates to a kind of electric machinery protection armour clamp device, especially a kind of stockbridge damper that can alleviate the vibration of overhead transmission line wind-engaging.

Background technology

Along with the development of superhigh pressure large capacity transmission technology, there is anti-corona poor performance in the stockbridge damper that electric machinery protection is at present used, and electromagnetic consumable is big, and the grip instability is easy to generate displacement under the effect of nature external force, seriously influenced result of use.Chinese patent 00255410.0 discloses a kind of novel combination stockbridge damper, it comprises wire clamp, steel strand wire, tup, the link of the tup that is connected with steel strand wire is provided with connecting hole, steel strand wire insert in the connecting hole fixing, the other end of tup is a sphere-like, connecting hole is the regular hexagon hole, respectively is provided with a tup at two 1 ends of steel strand wire, is provided with definite angle between two tups.This stockbridge damper exists electromagnetic consumable big, grip instability, defective such as effectiveness in vibration suppression is undesirable, and useful life is short.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can reduce that electromagnetic consumable, saves energy, grip are stable, damping property is good, the energy-saving vibration prevention hammer of long service life.

The object of the present invention is achieved like this: wire clamp adopts two semicircle Hafu type structures, the wire clamp outline is excessively slick and sly, the Kazakhstan furan of wire clamp is provided with hex hole, be provided with left-handed anti-skidding line in the hex hole, the lower end die casting of wire clamp is at the middle part of steel strand wire, and it is fastening with locking Non-return ring of screw serrated form and nut that the hemispherical head bolt passes wire clamp, steel strand wire two ends and hammer body die casting are connected as a single entity, hammer body adopts elbow fist shape, and the hammer body exterior contour is excessively slick and sly, and two hammer bodies are the 45-60 angle position.

The inner hole wall of the locking Non-return ring of screw serrated form is provided with and the corresponding lead angle locking tooth of thread pitch.

Wire clamp and hammer body are made with non-magnet material.

Material novelty of the present invention, structure uniqueness, outline slyness reduce corona discharge, reduce the electromagnetic energy loss, saves energy, discharge off design, grip is stable, can produce four resonance frequencys, be suitable for transmission pressure resonance self-frequency better, prevent conductor galloping, reduce the circuit amplitude, the vibrationproof performance is good, and the corrosion resistant ability is strong, long service life.

1 transmission pressure, 2 wire clamps, 3 left-handed anti-skidding lines, 4 hemispherical head bolts, 5 steel strand wire, 6 hammer bodies, the locking Non-return ring of 7 screw serrated forms, 8 hex holes, 9 lead angle locking tooths among the figure.

Embodiment

Embodiment: by wire clamp 2, steel strand wire 5, hammer body 6 is formed, wire clamp 2 adopts two semicircle Hafu type structures, wire clamp 2 outlines are excessively slick and sly, the Kazakhstan furan of wire clamp 2 is provided with hex hole 8, be provided with left-handed anti-skidding line 3 in the hex hole 8, the lower end die casting of wire clamp 2 is at the middle part of steel strand wire 5, hemispherical head bolt 4 pass the locking Non-return ring 7 of wire clamp 2 usefulness screw serrated forms and nut fastening, steel strand wire 5 two ends and hammer body 6 die casting are connected as a single entity, the non-magnetic conduction zinc alloy material of hammer body 6 usefulness is made, be elbow fist shape, hammer body 6 exterior contours are excessively slick and sly, two hammer bodies are 50 angle positions, the inner hole wall of the locking Non-return ring 8 of screw serrated form is provided with and the corresponding lead angle locking tooth 9 of hemispherical head bolt 4 thread pitch, by external force fastening after, lead angle locking tooth 9 embeds screw thread, locking retaining, the non-magnetic conduction high-strength aluminum alloy material that wire clamp 2 usefulness are close with the transmission pressure coefficient of expansion is made, with hemispherical head bolt 4, locking Non-return ring 8 of screw serrated form and nut are fixed on the transmission pressure, it is excessively slick and sly that whole stockbridge damper is exterior contour, the discharge off design reaches 20 times than the stockbridge damper saves energy of using on the present power network.
