Abstract
The utility model relates to a pre-twisted wire rotary chuck-type shock-proof hammer, which is characterized in that a wire clip adopts a multilayer rotary structure, the wire clip is provided with a plurality of helical pre-twisted wires, and the pre-twisted wires wraps the outer surface of a power transmission line. The rotary structure of the wire clip is favorable for the rotation of the pre-twisted wire rotary chuck-type shockproof hammer, when a conducting wire on a circuit is gradually misted and iced, the pre-twisted wire on the pre-twisted wire rotary chuck-type shockproof hammer makes a reciprocating rotation of a certain angle relatively to a conducting wire, so that the pre-twisted rotary chuck-type shockproof hammer is kept relatively independent relative to the conducting wire, the pre-twisted rotary chuck-type shockproof hammer is free from being frozen with the conducting wire into a whole, the normal power characteristic of the pre-twisted rotary chuck-type shockproof hammer can be guaranteed, and the conducting wire is protected against damage.
Description
Technical field
The utility model relates to faces upward the device that overhead transmission line processed is waved, particularly the conductor spacer between wire two two-phases.
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, the destruction main manifestations is that flashover, tripping operation, electric arc burn, gold utensil, insulator damage, disconnected strand of wire, broken string, falls tower etc.Usually, the span of high-tension overhead line is larger, 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 wire; When overhead wire is subject to doing the time spent perpendicular to the wind-force of line direction, can form the stabilizing vortex of pressing the certain frequency alternatively up and down at its back side, cause wire periodic vibration ripple, form nodal point at wire and wire clamp interface, no matter any wavelength or frequency, all be that the vibration of built on stilts wire clamp exit is the most serious, at the crest that node is nearest stockbridge damper is installed, because the inertia effect of anti-vibration hammer, make connect tup steel strand wire constantly on, lower bending, between the steel strand wire thigh and storeroom all produce friction and consume vibrational energy, make hearsay can not produce significantly vibration to what the vibrational energy of wire was consumed; 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 wire, when conductor vibration, stockbridge damper also vibrated, and the steel strand wire on the stockbridge damper drive the vibrational energy that tup consumes wire.But when this type of stockbridge damper was used for light, heavy icing area, because the effect of ice is frozen into one to wire and stockbridge damper when whole fully, stockbridge damper lost 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 wire, make stockbridge damper lose the deficiency of application function, the utility model provides a kind of preformed armor rods revolution chuck type stockbridge damper, this preformed armor rods revolution chuck type stockbridge damper is because it can have to wire the repeatedly rotation of certain angle, and it generally can not be frozen into an integral body with wire fully in freezing environment.
The technical scheme that its technical problem that solves the utility model adopts is: the wire clamp head of preformed armor rods revolution chuck type 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 by connector with the wire clip body cover plate by wire clip body; Interior revolving body forms by the revolution chuck is set in the stainless steel lining in two, and the revolution chuck links to each other by connector in two, and the outer surface of revolution chuck respectively is provided with the wire casing of an indent in two; 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 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 by 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 by 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 threaded bolt of cup head by 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 beneficial effects of the utility model are; the revolving structure of clamp head is conducive to the rotation of preformed armor rods revolution chuck type stockbridge damper; when the wire on the circuit in the process that produces gradually mist pine, icing; the relative wire of preformed armor rods on the preformed armor rods revolution chuck type stockbridge damper produces the reciprocating rotation of certain angle; make the relative wire of preformed armor rods revolution chuck type stockbridge damper can keep relative independence; can not become an integral body with wire is freezing, can guarantee its normal power characteristic, guardwire does not damage.
