Abstract
Provided is a preformed armour rod rotation chuck-type shockproof hammer. A line clamping head adopts a multilayer rotation structure, a plurality of spiral preformed armour rods are arranged on the line clamping head, and the preformed armour rods are wrapped on the outer surface of a transmission line. The rotation structure of the line clamping head is favorable to rotation of the preformed armour rod rotation chuck-type shockproof hammer, reciprocation rotation in a certain angle is formed between the preformed armour rods of the preformed armour rod rotation chuck-type shockproof hammer and a lead in the process that the lead on the line gradually produces misty pine and icing, the preformed armour rod rotation chuck-type shockproof hammer can keep relative independent relative to the lead, the preformed armour rod rotation chuck-type shockproof hammer and the lead cannot be frozen to form a whole, normal power characteristics can be guaranteed, and the lead can be protected and free of damage.
Description
Technical field
The present invention relates to face upward device, particularly lead that the system overhead transmission line the waves conductor spacer between mutually in twos.
Background technology
Conductor vibration is the key factor that threatens the overhead transmission line safe and stable operation with waving; China is vibration and waves one of the most serious country of disaster; Vibration and wave can cause huge destruction to transmission line; Destroy and to show as mainly that flashover, tripping operation, electric arc burn, gold utensil, insulator damage, disconnected strand of lead, broken string, fall tower etc.Usually, the span of high-tension overhead line is bigger, and shaft tower is also higher, in order to alleviate near the generally stockbridge damper of the installation some suspension wire clamp of waving of lead; When overhead wire receives the wind perpendicular to line direction, can form the stabilizing vortex of pressing the certain frequency alternatively up and down at its back side, cause lead periodic vibration ripple; Form nodal point at lead and wire clamp interface; No matter any wavelength or frequency all are that the vibration of built on stilts wire clamp exit is the most serious, at the crest that node is nearest stockbridge damper are installed; Because the inertia effect of stockbridge damper tup; Make the continuous upper and lower bending of steel strand wire that connects tup, between the steel strand wire thigh and storeroom all produce friction and consume vibrational energy, what make that hearsay gives that the vibrational energy of lead is consumed can not produce significantly vibration; Because remaining energy reduces, the amplitude of overhead wire reduces, and the energy of stockbridge damper consumption also descends with amplitude, and last energy reaches balance, and overhead wire can only be with very low amplitude vibration.
After general stockbridge damper was installed on the lead, when conductor vibration, stockbridge damper also vibrated, and the steel strand wire on the stockbridge damper drive the vibrational energy that tup consumes lead.But when this type of stockbridge damper is used for gently, during heavy icing area, because the effect of ice is frozen into one to lead and stockbridge damper when whole fully, stockbridge damper loses the function that prevents and suppress conductor vibration at this moment when circuit.
Summary of the invention
Wave transmission line is caused considerable damage in order to overcome transmission line wire; Under freezing effect, can be frozen into an integral body to existing stockbridge damper and lead; Make stockbridge damper lose the deficiency of application function; The present invention provides a kind of preformed armor rods revolution chuck formula stockbridge damper, and this preformed armor rods revolution chuck formula stockbridge damper be because it can have the rotation repeatedly of certain angle to lead, can in freezing environment, not be frozen into an integral body fully with lead as the one of which.
The technical solution adopted for the present invention to solve the technical problems is: the wire clamp head of preformed armor rods revolution chuck formula stockbridge damper links to each other with the stage casing of steel strand wire, and just the two ends of twisted wire respectively link to each other with firm sleeve pipe, and each firm sleeve pipe links to each other with tup; Be provided with interior revolving body in the external gyrorotor of wire clamp head, be provided with damping rubber in the interior revolving body; External gyrorotor is linked to each other through connector with the wire clip body cover plate by wire clip body; Interior revolving body is formed by the revolution chuck is set in the stainless steel lining in two, and the revolution chuck links to each other through connector in two, and the outer surface that turns round chuck in two respectively is provided with the wire casing of an indent; Be provided with preformed armor rods in the wire casing, the two ends of preformed armor rods are helical form, and the interlude of preformed armor rods is a straightway, and the straightway of preformed armor rods is put into wire casing.
A kind of prioritization scheme of such scheme is: the wire clamp head becomes hexagon to link to each other with the stage casing of firm twisted wire through crimping, and just the two ends of twisted wire become hexagon to link to each other with firm sleeve pipe crimping.
The another kind of prioritization scheme of such scheme is: two tups are around the angled symmetry of steel strand wire.
Another prioritization scheme of such scheme is: wire clip body links to each other with the cup head hole pin through cylindrical pins with the wire clip body cover plate.
Another prioritization scheme of such scheme is: the revolution chuck links to each other with the cup head threaded shank through cup head pin with holes in two.
Also a kind of prioritization scheme of such scheme is: put into two preformed armor rodses in each wire casing.
The invention has the beneficial effects as follows; The revolving structure of clamp head helps the rotation of preformed armor rods revolution chuck formula stockbridge damper, when the lead on the circuit in the process that produces mist pine, icing gradually, the reciprocal rotation that the relative lead of preformed armor rods on the preformed armor rods revolution chuck formula stockbridge damper produces certain angle; Make the relative lead of preformed armor rods revolution chuck formula stockbridge damper can keep relative independence; Can not become an integral body with lead is freezing, can guarantee its normal power characteristic, guardwire does not damage.
