Background technology
The strain insulator joint is the special-purpose gold utensil of a kind of built on stilts power transmission and transformation line, is used for the backguy part of shaft tower more, is extensive use of in power transmission and transformation line is built, and it mainly acts on is that aerial condutor is fixed on continuing on the strain insulator shaft tower or to aerial condutor.
Strain insulator joint of the prior art usually by wire clamp be connected the steel anchor and form, be mainly used in present a kind of steel reinforced aluminium conductor that generally uses.Aluminum pipe on the power transmission and transformation line cross-under wire clamp, steel core wherein be connected the steel anchor and connect, aluminum steel and wire clamp make it to link into an integrated entity by the hydraulic press upsetting pressure.The main pulling force that steel core carrying power transmission and transformation line is suffered also passes to connection steel anchor.Recently, a kind of high-strength carbon fiber composite core aluminum stranded wire is succeeded in developing, and the carbon fiber complex core of this novel aluminum twisted wire does not have spiral to curl up structure, and above-mentioned strain insulator joint no longer can clamp this novel aluminum twisted wire, thereby no longer suitable.
At present, a kind of Wedge-type strain insulator joint that is used for steel reinforced aluminium conductor is arranged abroad, be provided with spring, several voussoirs and the fixing matrix of voussoir in wire clamp, all pulling force are by wedge clamp body and voussoir cable to be held with a firm grip to fix.The strain insulator joint design relative complex of this Wedge-type, and because several voussoirs are discrete, inhomogeneous to the grip force at each position of aluminium stranded conductor, influence the clamping effect of strain insulator joint to lead.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, designs a kind of high-strength carbon fiber composite core aluminum stranded wire and uniform a kind of wedge shape strain insulator joint of grip force of being applicable to, it is realized by following technical scheme:
Comprise that one contains the binding clip of aluminum pipe, also comprise fixing clamper, wedge pipe, fixing clamper is fixed in the described aluminum pipe, and the wedge pipe is plugged in the wedged hole of fixing clamper correspondence.
Two ends of described wedge pipe are provided with orthogonal radial slot.
The gradient of the described wedge pipe outside conical surface is less than the angle of friction of material.
Described binding clip is provided with and connects the steel anchor, an end that connects the steel anchor inserts in the aluminum pipe and with an end spiral of wedge pipe and is connected, moving axially when connecting steel anchor helical rotation can promote the wedge pipe and move in the corresponding wedged hole of fixing clamper, and the other end that connects the steel anchor is provided with connecting ring.
The aluminum pipe of described binding clip is built-in with bushing pipe.
Described binding clip is provided with securing member.
The beneficial effects of the utility model are: the structure in the wedged hole that the wedge pipe is plugged on the fixing clamper correspondence of employing, and orthogonal radial slot is set at two ends of wedge pipe, make the lead of being held with a firm grip stressed evenly, functional reliability is higher, set up on the defeated modified line road that adapts to a kind of energy-conservation, high-tensile, low arc drop, in light weight, corrosion resistant carbon fiber complex core aluminium stranded conductor, promote to make promoting the use of of this novel aluminum twisted wire, help the update of power transmission and transformation line.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Contrast Fig. 1, wedge shape strain insulator joint of the present utility model is by binding clip 7, connection steel anchor 5, and fixing clamper 3, wedge pipe 4 are formed.The less aluminum pipe of one resistivity 2 is arranged on the binding clip 7, have reliable electric conductivity to guarantee wedge shape strain insulator joint, in order to bear the current-carrying function of overhead transmission line.Fixing clamper is fixed in the aluminum pipe 2, is provided with a wedged hole with certain taper in it, and wedge pipe 4 outsides are the taper seats that have with the same tapering of above-mentioned wedged hole, and wedge pipe 4 is plugged in the wedged hole of fixing clamper.An end that connects steel anchor 5 inserts in the aluminum pipe 2 and with wedge Guan Yiduan spiral and is connected, and moving axially when connecting steel anchor helical rotation can promote the wedge pipe and move in the wedged hole of fixing clamper correspondence.The other end that connects the steel anchor is provided with connecting ring, in order to link with the strain insulator shaft tower.Securing member 6 is to be used for drainage tube and binding clip 7 are linked.Bushing pipe 1 is the contact area that is used for increasing lead and aluminum pipe 2, is not more than the former desired value of uiform section lead to guarantee the resistivity behind the strain insulator coupling compression joint.
Strain insulator joint of the present utility model also can be used as continuing of aerial condutor, this kind situation does not need to connect steel anchor 5, just symmetry is equipped with a fixing clamper 3 and wedge pipe 4 in the aluminum pipe 2 of wire clamp 7, sees also according to Fig. 2, and the strain insulator joint of this moment is used for two connections between the lead.
Contrast Fig. 3 is respectively equipped with flute length radially on the biend of wedge pipe 4, and groove depth radial slot 8, two radial slots 8 in axial direction are vertical mutually.Wedge pipe 4 usefulness stainless steels are made, and the gradient of the outside conical surface of its pipe makes it have auto-lock function in the wedged hole of fixing clamper less than the angle of friction of material, and to guarantee reliable grip force, the lead of holding with a firm grip can not become flexible.
During use, earlier carbon fiber complex core is penetrated in the wedge pipe 4 of collapsible slip, the steel anchor 5 that is rotatably connected then connects steel anchor 5 and moves axially in the turn, promote wedge pipe 4 and move forward, wedge pipe 4 constantly moves towards the gradually little place of wedged hole diameter, its all side is subjected to the restraining force of wedge shape hole wall, because radial slot 8 is arranged, the tube wall of wedge pipe 4 is out of shape to central elastic, the radial dimension of wedge pipe 4 diminishes, and tube wall is more held the lead that penetrates.Connect steel anchor 5 turn many more forward, the degree that the tube wall of wedge pipe 4 is held with a firm grip to the lead in it is firm more.
The utility model strain insulator joint ground is fine to have solved the problem that existing product can not satisfy Overhead Transmission Line Construction, and solution is simple, thereby the applicability of product is improved greatly.
