Description
Technical field
The utility model relates to electric power transmission line antihunting device technical fields, more particularly, to a kind of new-type antiskid
Set.
Background technique
Overhead transmission line when being acted on by gentle breeze, lead, the leeward of ground wire by generate certain frequency become alternatively up and down
The air-flow vortex of change, the air-flow vortex make overhead line by the pulsed force function of upper and lower alternation.When the alternating of air-flow vortex changes
When frequency is equal with the intrinsic natural frequency of vibration of overhead line, resonance is generated in vertical plane, that is, causes the vibration of overhead line.Continue
Aeolian vibration to will cause fitting abrasion, the fatigue of conducting wire stranded, or even broken string threatens the safe operation of route very big.For
Aeolian vibration harm caused by overhead transmission line is prevented, most common method is that damper is installed on overhead transmission line.
The fastening bolt of damper may be loosened due to many reasons, so that the grip between shockproof hammer thread clip and conducting wire
Become smaller, wire clamp loosens and damper is caused sliding phenomenon occur.Anti-vibration effect weakens or failure, conductor vibration aggravation, insulator
Suspension clamp is in high vibration state for a long time, and wire clamp exit cannot get due protection, cause conducting wire and overhanging golden tool
Hull junction conducting wire absorbs oscillation energy, and metal fatigue accelerates, and generates fretting wear between strands, ultimately causes conducting wire fatigue
It is stranded, and damper can also wear conducting wire during displacement, directly threaten the safe operation of transmission line of electricity.
The wire clamp material of damper has cast steel and two kinds of high-strength aluminum alloy, to prevent damage wires, when installation, and cast steel folder
Head is installed using winding aluminium armor tape mode, and aluminium alloy clamping head is used to be installed without winding aluminium armor tape mode.Data statistics is shown, is used
The damper that winding aluminium armor tape mode is installed is easier that sliding phenomenon occurs.
The main reason for generating sliding is that shockproof hammer thread clip grip is insufficient, and the friction of wire clamp and conducting wire is caused to reduce and cause.
Grip deficiency is mainly generated by several reasons: first is that route is chronically in vibration environment, the fastening bolt of wire clamp loosens;Second is that
Wire clamp material, conducting wire and aluminium armor tape nonhomogeneous hardness are big, even if using high-strength aluminum alloy wire clamp, wire clamp hardness is also much larger than leading
Line aluminium stock hardness, generates under Long-term Vibration impact between wire clamp and conducting wire and is squeezed and deformed accumulation, and wire clamp loosens;Third is that operation work
Condition lower wire elastic elongation and permanent creep elongation, wire clamp loosen;Fourth is that construction reason, such as cable clip bolt fastening not enough,
Aluminium armor tape winds nonconforming etc..
Currently, to have by improving wire clamp be loose-leaf structure formula, prevents fastening bolt loose type, adds clamp springs at wire clamp
Formula, wire clamp internal layer increase a variety of damper slip-proof ways such as rubber pad, inner metal sleeve formula, pre- hinge silk rubber sleeve type.Wire clamp changes
It still can not change grip insufficient front three reason for loose-leaf structure formula;Prevent fastening bolt loose type from can not change grip
Second and third insufficient reason;Adding clamp springs formula at wire clamp, structure is complicated, is able to satisfy the spring execute-in-place of big chucking power
Difficulty, it is also big that the later period overhauls difficulty, reliability, less economical;Wire clamp internal layer increases rubber pad and pre- hinge silk rubber sleeve type
Coefficient of friction is increased, but there are problem of aging;Inner metal sleeve formula, the such method mentioned in document at present are only used in aerial
On ground wire, ground wire is steel strand wires, and conducting wire is steel-cored aluminium strand, and the aluminum metal inner sleeve of this ordinary construction can by tightening bolt
Aluminum metal inner sleeve caused by energy can be squeezed and deformed, and form it with ground wire certain chimeric, if this big fastening force is used in
On conducting wire the outer layer aluminum steel of conducting wire will be deformed, cause very big with stress at conductive contact, be easier to broken string stock occur existing
As, while the outer surface of inner metal sleeve and wire clamp are possible there are still sliding, and are applicable only to ground wire.
Above several methods for preventing damper from sliding, from the complexity of engineering, service life, reliability, economy etc.
Many factors are fastidious, these modes all have certain problems;It is not also promoted the use of on Practical Project, not can prove that
Mode can reach preferable damper antiskid effect.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of new-type antiskid set, adopts
The structure and fastening means of original damper can not be changed with this Anti-slip cover, when installation, the wire clamp of damper passes through Anti-slip cover
Closely chimeric between conducting wire, moderate chucking power is just able to satisfy the frictional force for considerably increasing Anti-slip cover and conducting wire, in structure
On ensure that and be difficult to generate sliding between Anti-slip cover and conducting wire, the wire clamp of damper is clamped between two set shoulders of Anti-slip cover,
