Abstract
The utility model discloses an articulated type anti-vibration hammer for overhead power transmission lines, comprising a wire clamp body and a wire clamp cover board which are articulated by a pin shaft; when in installation, the wire clamp body and the wire clamp cover board are opened and are not separated, the structure is compact and flexible, and the installation is simple and convenient; an anti-dropping rubber pad is arranged in the wire clamp body and the wire clamp cover board, and an anti-sliding stopping pin and a cotter pin are arranged at the middle-bottom part of the wire clamp body, thereby having high construction safety; the rational design of the compression amount of the rubber pad and the compression layout and good properties ensure the wire clamp of the anti-vibration hammer to have enough and durable gripping strength to the wires, thereby meeting the using requirements of power transmission lines for a long time; a hammer head and a steel strand are fixed by adopting a pressure welding process, thereby forming full and firm contact and increase the gripping strength of the hammer to the steel strand; the optimal design of the appearance of the product and the selection of non magnetic anti-corrosion material can lead the anti-vibration hammer to have remarkable energy-saving effect and good corrosion resistance.
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, novel locking energy-saving vibration prevention hammer that grip is enough and lasting.
The utility model adopts following technical scheme: a kind of overhead transmission line radial type stockbridge damper, comprise wire clip body and wire clamp cover plate, wire clip body and wire clamp cover plate are hinged by bearing pin, be provided with rubber blanket in wire clip body and the wire clamp cover plate, be provided with barrier pin and split pin below in wire clip body, the below crimping of wire clip body is steel strand wire fixedly, steel strand wire two ends crimping fixed hammer.
Wire clamp adopts non magnetic high-strength aluminum alloy material, and hinging pin shaft, barrier pin etc. adopt non magnetic austenitic stainless steel, and tup adopts the allumen material.
Compared with prior art, the utlity model has following advantage:
1, the utility model compact conformation is flexible, uses simple installation.Because wire clip body and cover plate be hinged to become a mobilizable integral body, to hang in the process of lead opening cover plate, wire clip body does not separate with cover plate; After closing tight cover plate, insert the pin barrier and get final product.
2, the utlity model has bigger working security.Since on the hemisphere jut of rubber blanket bottom and the wire clamp tubaeform through hole clamp-on cooperation, during construction, rubber blanket will stably hang on the wire clamp and can not come off easily; Design has a step on the barrier pin, can prevent that the accident after pin inserts from dropping, and insert split pin at the pin afterbody again, makes fail safe higher.
3, the utility model can guarantee enough and lasting grip, can satisfy the long-term instructions for use of transmission line.Because the appropriate design of rubber blanket decrement and compression layout, and the rubber blanket of selecting for use has good performance, therefore not only can guarantee the grip that requires, and can keep its original grip constant for a long time, prevented the loosening slippage of stockbridge damper.
4, 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.
5, the utlity model has obvious energy-saving effect.Wire clamp adopts non magnetic high-strength aluminum alloy material, joint pin, barrier pin etc. adopt non magnetic austenitic stainless steel, greatly reduce the loss of magnetic hysteresis eddy current electric energy, and the design of the slyness of wire clamp and tup, corona is no longer produced, and comparing traditional stockbridge damper more has energy-saving effect.
6, the utlity model has superior decay resistance.Because wire clamp adopts aluminum alloy material, hinging pin shaft, barrier pin etc. adopt stainless steel, and tup adopts the allumen material, makes product more corrosion-resistant, are fit to the use than heavily contaminated or coastal area.
