Abstract
The utility model discloses a bolt type strain clamp for overhead transmission lines. A plurality of sets of pressing blocks are improved on the basis of the original wire clamp, so as to facilitate the construction operation, guarantee enough and lasting grip strength of the wire clamp to conducting wire, and meet the long-term use requirement of the transmission line. The strain clamp has an optimally designed shape and adapts nonmagnetic corrosion-resistant material, thereby having remarkable energy saving effect and superior corrosion resistance.
Description
Technical field
The utility model relates to a kind of overhead transmission line bolt type strain clamp, relates in particular to a kind of can bearing than big load, the bolt type strain clamp that energy-saving effect is arranged again easy to install and use.
Background technology
Strain clamp is used for lead or lightning conducter are fixed on the strain insulator string of non-rectilinear shaft tower, plays the anchoring effect.
There is construction and installation inconvenience in present widely used bolt type strain clamp owing to multiple reasons such as himself structures, and then influence is to the phenomenon of lead grip.
Present widely used bolt type strain clamp 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 distributed architecture rationally, low energy loss, the superior novel bolt type strain clamp of decay resistance.
The utility model adopts following technical scheme:
A kind of overhead transmission line bolt type strain clamp comprises wire clip body, hangers bolt and U bolt, it is characterized in that, also comprises a briquetting, and described briquetting is arranged on the side-lower at wire clip body.
Described briquetting and U bolt are single-piece disjunctor fixed structure, and adopt the extruding fixed form.
The material briquetting of described wire clip body and wire clamp is non magnetic high-strength aluminum alloy.
Compared with prior art, the utlity model has following advantage:
1, the utility model compact conformation is flexible, uses simple installation safety.Penetrating lead and tightening U bolt and compress in the process of lead,, thereby greatly facilitating constructing operation because briquetting is fixed on the U bolt with fashion of extrusion and do not drop.
2, the utility model can guarantee enough and lasting grip, can satisfy the long-term instructions for use of transmission line.Owing to adopt single-piece disjunctor fixed structure, promptly be connected with single briquetting relative fixed respectively by several U bolts, can guarantee that briquetting evenly exerts pressure to lead when fastening successively tightening U bolt, and briquetting is often pushed down the phenomenon of lead with crooked dislocation form when having avoided the split structural design, thereby has guaranteed the grip to lead.
3, adopt special equipment and frock extruding fixing between U bolt of the present utility model and the briquetting, accurate positioning unanimity between U bolt and the briquetting, controllability height.
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, compares traditional cast iron bolt type strain clamp and has played good energy-saving and environmental protection effect.
5, the utlity model has superior decay resistance.Because the wire clamp of product main body adopts aluminum alloy material, makes product more corrosion-resistant, be fit to use than heavily contaminated or coastal area.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is briquetting of the present utility model and U bolt single-piece disjunctor fixed structure schematic diagram.
Wherein 1 wire clip body, 2 hangers bolts, 3 briquettings, 4U type bolt.
Embodiment
A kind of overhead transmission line bolt type strain clamp comprises wire clip body 1 and hangers bolt 2, assembles some groups of briquettings 3 and U bolt 4 at the side-lower of wire clip body 1.In wire clip body 1 wire casing, briquetting penetrates lead 53 times, tightens U bolt spare 4 in order, make briquetting 3 be fixed lead 5 after, be connected to strain insulator string by hangers bolt 2.
Securing members 4 such as briquetting 3 and U bolt are single-piece disjunctor fixed structure.
