Abstract

The utility model relates to a shockproof hammer, comprising a steel stranded wire, a steel wire rope hitch, two hammer bodies fixedly arranged at the two ends of the steel stranded wire, a connector fixedly arranged in the middle position of the steel stranded wire, and a wire clip fixed on a conducting wire, wherein the wire clip is provided with a sleeve arranged longitudinally and downwards, the steel wire rope hitch is accommodated in the inner cavity of the sleeve, the connector is provided with a protruded part extending upwards and longitudinally, a steel wire rope is fixedly arranged on the top end of the protruded part, the other end of the steel wire rope penetrates through the bottom wall of the sleeve to be fixedly connected with the steel wire rope hitch. According to the shockproof hammer, the connector is arranged between the wire clip and the steel stranded wire, and the steel wire rope connected to connector is buckled with the steel wire rope hitch arranged in the sleeve of the wire clip, so that the effect that the hammer bodies of the shockproof hammer, the steel stranded wire and the connector can rotate along with wind is realized, for the conducting wire, the shockproof hammer is more beneficial to weakening or absorbing vibration frequency, changing the swinging frequency of the line, and reducing the vibration or waving amplitude of the line.

Description

A kind of stockbridge damper

Technical field

The utility model relates to a kind of stockbridge damper, is specifically related to a kind of stockbridge damper that hangs on the transmission line.

Background technology

Known to a person skilled in the art, the effect of meteorological conditions such as overhead power line wind-engaging, ice, low temperature makes circuit produce vibration and waves, during vibration, frequency is higher and amplitude is very little, so make overhead wire at the suspension point place repeatedly by stubborn folding, cause fatigue of materials, cause disconnected strand, broken string accident at last; When waving, frequency is very low, and amplitude is very big, is easy to cause alternate flashover, causes serious accidents such as line tripping, power failure or burn lead.Therefore, stockbridge damper just arises at the historic moment for the electric armour clamp of eliminating the circuit self-vibration and eliminating the resonance that wind etc. causes as a kind of.

The wire clamp that stockbridge damper on the existing market generally comprises the hammer body that is connected the steel strand wire two ends and is articulated in the steel strand wire centre position, by wire clamp with the stockbridge damper hanging support on lead, yet in actual the use, because stockbridge damper is applied to the more abominable field of natural environment or air port, therefore, in rugged environment too, stockbridge damper plays prevents that conductor vibration or the effect of waving are very little.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, novel in design and can more effective reduction conductor vibration frequency or wave the stockbridge damper of amplitude.

For achieving the above object, the utility model adopts a kind of stockbridge damper, comprise steel strand wire, wire line hitch, be fixed on the steel strand wire two ends two hammer bodies, be fixedly installed on the connector in steel strand wire centre position and be used for being fixed on wire clamp on the lead, wherein said wire clamp has the sleeve that vertically arranges downwards, described wire line hitch is contained in the inner chamber of described sleeve, described connector has vertical upwardly extending protuberance, fixedly there is steel wire rope on the top of this protuberance, and the other end of described steel wire rope passes the diapire of sleeve and forms a fixed connection with wire line hitch.

By the above-mentioned improvement to prior art, owing between wire clamp and steel strand wire, connector is set, and this connector is by being arranged on wire line hitch in the wire clamp sleeve and the fastening of steel wire rope, reached the effect that the hammer body of stockbridge damper and steel strand wire and connector can rotate with the wind, for lead, stockbridge damper of the present utility model is conducive to weaken or absorb vibration frequency more, changes the circuit wobble frequency, reduces the vibration of circuit or the amplitude of waving.

Fig. 1 is the front view of the utility model embodiment.

Embodiment

As shown in Figure 1, specific embodiment of the utility model is a kind of stockbridge damper, comprise steel strand wire 1, wire line hitch 2, be fixed on two hammer bodies 3 at steel strand wire 1 two ends, be fixedly installed on the connector 4 in steel strand wire 1 centre position and be used for being fixed on wire clamp 5 on the lead, wherein said wire clamp 5 has the sleeve 50 that vertically arranges downwards, described wire line hitch 2 is contained in the inner chamber of described sleeve 50, described connector 4 has vertical upwardly extending protuberance 40, fixedly there is steel wire rope 41 on the top of this protuberance 40, and the other end of described steel wire rope 41 passes the diapire 51 of sleeve 50 and forms a fixed connection with wire line hitch 2.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and appended claim and the equivalent thereof of protection range that is required by the utility model defines.

Claims

1. stockbridge damper, it is characterized in that: comprise steel strand wire, wire line hitch, be fixed on the steel strand wire two ends two hammer bodies, be fixedly installed on the connector in steel strand wire centre position and be used for being fixed on wire clamp on the lead, wherein said wire clamp has the sleeve that vertically arranges downwards, described wire line hitch is contained in the inner chamber of described sleeve, described connector has vertical upwardly extending protuberance, fixedly there is steel wire rope on the top of this protuberance, and the other end of described steel wire rope passes the diapire of sleeve and forms a fixed connection with wire line hitch.
