Abstract

The invention relates to a pre-twisted rotation spacer rod which comprises a frame and a wire clamp arranged on the frame. Half of the wire clamp is of a rotating type, and the other half of the wire clamp is of a fixed type. The rotating wire clamp structure comprises a wire clamp head (1) for clamping a wire, the wire clamp head (1) is connected with a connecting plate (4) fixed to the frame through a wire clamp support sliding rod (3), the rear portion of the wire clamp head (1) is provided with a rotating circular groove (10), the support sliding rod (3) stretches into the rotating circular groove (10) and can rotate along the rotating circular groove (10). The pre-twisted rotation spacer rod is simple in structure. The rotating wire clamp comprises just a few simple parts but can better achieve the effect that the rotating wire clamp rotates along with the wire, so that the sufficient condition for damaging waving of all wires is achieved, and the purpose of controlling waving of the wires is achieved.

Description

A kind of preformed revolution conductor spacer

Technical field

The present invention relates to a kind of electric armour clamp, relate to specifically a kind of preformed revolution conductor spacer.

Background technology

Waving of overhead transmission line is a kind of air force wild effect, is a kind of low frequency causing under wind-force effect after the inhomogeneous icing of transmission line wire, the chattering of large amplitude.Once conductor galloping forms, and can cause great destruction, thereby threaten the safe operation of transmission line to transmission line.Wave often cause wire whiplash, burn, disconnected thigh, broken string, gold utensil heavy wear, rupture, come off, electric insulator steel foot ruptures, shaft tower is toppled over, line tripping etc., thereby easily causes the serious accidents such as large-area power-cuts, brings great economic loss to society.

It is the key factor that threatens overhead transmission line safe and stable operation that transmission line wire is waved, one of country that disaster is the most serious is waved by China, wave and can cause huge destruction to transmission line, destruction main manifestations is flashover, tripping operation, electric arc burn, gold utensil, insulator damage, and disconnected strand of wire, broken string fall tower etc.

In order to solve the situations such as light, heavy icing area circuit is waved, now invent a kind of preformed revolution spacer rod device.Conventionally, the span of high-tension overhead line is larger, and shaft tower is also higher, in the time that wire is subject to strong wind and blows, stronger vibration can occur.When vibration meets some requirements.That phase conductor can be waved, and will cause wire fatigue damage, makes wire that disconnected strand, broken string occur.Sometimes wave and also can destroy gold utensil and insulator and steel tower when strong.

The patent that application number is 2012205111149 for this reason discloses a kind of wave-proof clip of output formula revolution conductor spacer, it is fixed that its total design philosophy is that half wire clamp is set to, half wire clamp is set to rotary type, in the time running into strong wind weather, avoids large wind-induced conductor galloping like this; In running into sleety weather, in Anti-galloping, eliminate ice and snow.Thereby guarantee that wire is under wind-force, Ice Load, make wire rotate certain angle and eliminate the condition of waving generation, effectively suppress conductor galloping, keep spacing each other.

But the technical scheme complex structure that above-mentioned patent provides, is in use easily damaged.

Summary of the invention

The present invention is directed to above-mentioned defect, it is a kind of simple in structure that object is to provide, and can realize the preformed revolution conductor spacer of Anti-galloping.

The technical solution used in the present invention is for this reason: the present invention includes framework and be arranged on the wire clamp on framework, wherein the wire clamp of half is rotary type, second half wire clamp is fixed, described rotary type cable clamp structure is: comprise the wire clamp head (1) of clamping wires, wire clamp head (1) is connected with the connecting plate (4) being fixed on framework by wire clamp supporting slider (3);

Described wire clamp head (1) rear portion is provided with rotates circular groove (10), and supporting slider (3) stretches to rotates in circular groove (10) and can rotate along rotating circular groove (10).

Advantage of the present invention is: the present invention is simple in structure, rotary type wire clamp only comprises several simple parts, but can well realize rotary type wire clamp follows wire and rotates together, destroy thereby reach the sufficiency that every phase conductor is waved, reach the object that pilot is waved.

Brief description of the drawings

Fig. 1 is structural representation of the present invention.

Fig. 2 is the structural representation of rotary type wire clamp.

In figure, 1 is that wire clamp head, 2 is for inner liner rubber watt, 3 is for wire clamp supporting slider, 4 is for wire clamp head support and connection plate, 5 is for bolt 5,6 is for plain washer, 7 is for spring washer, 8 is for nut, 9 is for closed pin, 10 is for rotating circular groove.

Embodiment

The half wire clamp of conductor spacer of the present invention forms a preformed revolution conductor spacer by fixed chuck A, half by turning round wire clamp B and deckle board C bolted on connection, and the connection of conductor spacer and wire is wrapped on the fixing clamper and revolution wire clamp of wire and conductor spacer by one group of preformed armor rods 11.

Preformed revolution rotary wire clamp for conductor spacer head B by active line chuck 1, inner liner rubber watt 2(also can), wire clamp supporting slider 3, wire clamp head support and connection plate 4, connect and be combined into by bolt 5, plain washer 6, spring washer 7, nut 8, small closed end pin 9.

The front portion of active line chuck is by the wire casing of a clamping wires, there is half arc grooved of one 180 degree to rotate circular groove below, in the time that wire wants product to rotate, the assembly being connected with wire clamp supporting slider 5 by wire clamp support and connection plate 4 rotates in half camber circular groove of 180 degree.

In the time that line conductor will be waved, preformed turning spur chuck one end can followed wire and rotated together, and opposite side fixing clamper does not produce any rotation, reaches unbalanced moving, reach and destroy the sufficiency that every phase conductor is waved, reach the object that pilot is waved.

Claims (1)

1. a preformed revolution conductor spacer, comprise framework and be arranged on the wire clamp on framework, wherein the wire clamp of half is rotary type, second half wire clamp is fixed, it is characterized in that, described rotary type cable clamp structure is: comprise the wire clamp head (1) of clamping wires, wire clamp head (1) is connected with the connecting plate (4) being fixed on framework by wire clamp supporting slider (3);
