Abstract
The utility model discloses a pre-twisted anti-vibration hammer for an overhead transmission wire. The pre-twisted anti-vibration hammer comprises a wire clamp body which is suspended on a lead wire; a steel wire is fixed below the wire clamp body in a pressed welding way, and hammer heads are fixed at both ends of the steel wire in a pressed welding way. The utility model is characterized in that pre-twisted anti-vibration hammer also comprises a pre-twisted wire which is twisted on the wire clamp body and the lead wire so that the wire clamp body and the lead wire are fixed together. The pre-twisted anti-vibration hammer has compact and flexible integral structure and easy, convenient and safe installation; the relative fixing of the positions of a wire clamp and the lead wire of the anti-vibration hammer can be ensured due to the banding force of the pre-twisted wire on the lead wire and the match of the pre-twisted wire and a diamond raised limit structure positioned at the upper end part of the wire clamp body, so that the requirement on the long-term use of the transmission wire is met; the hammer head is fixed with the steel wire by the pressed welding process to realize the complete and firm contact, so that the holding power of the hammer head for the steel wire is increased; in addition, the pre-twisted anti-vibration hammer has obvious energy-saving effect and superior corrosion resistance due to the optimization design of the appearance of a product and the use of non-magnetic anticorrosion materials.
Description
Technical field
The utility model relates to a kind of overhead transmission line stockbridge damper, relates in particular to a kind of stockbridge damper that had not only prevented the sliding and corrosion of pine but also energy-saving effect is arranged.
Background technology
The aeolian vibration of overhead transmission line conductor is to threaten one of key factor of transmission line safe operation, by stockbridge damper is installed on lead, can effectively reduce the aeolian vibration level of lead, and it is suppressed in the safe range.
Present widely used stockbridge damper exists the stockbridge damper wire clamp to be difficult for holding with a firm grip lastingly lead owing to multiple reasons such as himself structure and installations, and then the stockbridge damper phenomenon of loosening slippage on the line takes place.Stockbridge damper has the design and installation position of its regulation on transmission line, in case after the slippage, will completely lose its vibration-isolating effect, if untimely discovery is also corrected, finally cause the vibrating fatigue of overhead transmission line conductor to be destroyed possibly.
Present widely used stockbridge damper is owing to multiple reasons such as himself structure and materials, and the loss of electric energy such as ubiquity corona, magnetic hysteresis eddy current can not have been satisfied the energy-conserving and environment-protective requirement that transmission line improves day by day.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation flexibly, use simple installation, grip is enough and lasting, low energy loss, the superior novel locking energy-saving vibration prevention hammer of decay resistance.
The utility model adopts following technical scheme:
A kind of overhead transmission line stockbridge damper, comprise the wire clip body that is suspended on the lead, the fixing steel strand wire of crimping below wire clip body, at steel strand wire two ends crimping fixed hammer, it is characterized in that, also comprise preformed armor rods, described preformed armor rods is wrapped on wire clip body and the lead wire clip body and lead fixed is in the same place.
Described wire clip body has hangs lead rear defence accidental structure.
Described anti-accidental structure is the hook-type wire clip body.
Described wire clip body is provided with anti-loosening structure.
Described anti-loosening structure has the rhombus projection for being arranged on the wire clip body upper end.
Described tup is ball bone shape or tuning fork shape.
Described tup is ball bone shape or tuning fork shape.
Compared with prior art, the utlity model has following advantage:
1, the utility model compact conformation is flexible, uses simple installation safety.Need not erecting tools, wire clip body is hung lead after, directly twine preformed armor rods and get final product.And the shape-designing of wire clip body uniqueness, being necessary for curved path when making it hang into (drawing off) lead hangs into (drawing off), and in the installation process (after referring to that wire clip body is hung lead, before the installation preformed armor rods) colliding with unexpectedly mostly is force of the breath and is single direction, so be difficult for causing the accidental of wire clip body.
2, the utility model can guarantee enough and lasting grip, can satisfy the long-term instructions for use of transmission line.Because preformed armor rods has tightening force to lead, and then generation frictional force can guarantee the not relative slippage of preformed armor rods and lead, again because the cooperating of the protruding position limiting structure of preformed armor rods and wire clip body upper end rhombus, guaranteed the relative fixed of wire clip body and preformed armor rods, final effect is exactly that stockbridge damper will not produce loosening and slippage to lead.
3, tup of the present utility model and steel strand wire adopt compression joint technique to fix, and have avoided the flanging process and the casting of metals technology of relative complex, and between steel strand wire and tup because of crimping can form abundant firm contacting, increased the grip of tup to steel strand wire.
4, the utlity model has obvious energy-saving effect.Wire clamp adopts non magnetic high-strength aluminum alloy material, greatly reduces the loss of magnetic hysteresis eddy current electric energy, and the design of the slyness of wire clamp and tup, and corona is no longer produced, and comparing traditional stockbridge damper more has energy-saving effect.
5, the utlity model has superior decay resistance.Because wire clamp adopts aluminum alloy material, tup adopts the allumen material, makes product more corrosion-resistant, is fit to the use than heavily contaminated or coastal area.
