Abstract

This utility model relates to an insulation tension resistant wire clamp, comprising a wire clamp and a wedge block. The wire clamp comprises a pedestal and a U-shaped bolt which is connected to the pedestal. The top of the end with a relatively small caliber of the pedestal is provided with a circular hole lifting lug; one side of the pedestal is provided with a T-shaped chamber; a reinforcement rib is arranged on the outer surface of one side of the pedestal which has no a chamber; two sides of the bottom end of the pedestal are provided with lifting lugs for the U-shaped bolt to pass through; the pedestal is inserted in to a wedge block from the end with a relatively large caliber; the wedge block is constituted by two identical small wedge blocks; and the integral wedge block is trapezoid; one-direction sawtooth is uniformly positioned on the inner side of the small wedge block along the long axis of the small wedge block; and a frustum-shaped chamber is formed in the middle part of the integral wedge block after splicing two small wedge blocks. The insulation tension resistant wire clamp is advantageous in that the malposition between the two small wedge blocks during the usage can be avoided through a limiting device.

Description

A kind of insulating tension clamp
Technical field
The utility model relates to a kind of insulating tension clamp, specifically a kind of device of avoiding wedge in use to occur inconsistent phenomenon.
Background technology
Strain clamp is for fixing cord, to bear wire tension, and wire is hung to the gold utensil on strain insulator-string group or shaft tower.Strain clamp is used for corner, continues, and the connection of terminal.Spiral aluminium-clad steel wire has extremely strong strain insulator intensity, without concentrated stress, optical cable is played to the effect of protection and auxiliary vibration damping.A whole set of optical cable strain hardware fitting comprises: strain insulator preformed armor rods, supporting connection gold utensil.Grip of clamp is not less than the 95% easy for installation, quick of the specified tensile strength of optical cable, has reduced construction cost.Be applicable to span≤100 meter, the ADSS lightguide cable link of circuit corner <25 °.Strain clamp is used for wire or lightning conducter to be fixed on non-rectilinear shaft tower strain insulator string, and the effect of weighing anchor, is also used for fixing the bracing wire of bracing wire shaft tower.
Strain clamp, by the difference of structure and mounting condition, can be divided into two classes haply.The first kind: strain clamp will bear whole pulling force of wire or lightning conducter, grip of clamp is not less than and is mounted 90 of wire or the specified stretching resistance of lightning conducter, but not as electric conductor.This class wire clamp can also be pulled down after wire is installed, and uses separately.Such wire clamp has bolt-type strain clamp and wedge shape strain clamp etc.Equations of The Second Kind: strain clamp is except bearing whole pulling force of wire or lightning conducter, again as electric conductor.Once after therefore this class wire clamp is installed, just can not go again dismounting, be called again dead wire and press from both sides.Owing to being electric conductor, the installation of wire clamp must be in accordance with conscientiously carrying out about the regulation of fitting operation rules.
At present, wedge shape strain clamp in using on market, its wedge is spliced and combined and is formed by two little wedges, but do not have any jockey on two little wedges, therefore after long-time use, may there is the phenomenon of dislocation in two little wedges, finally make overall wedge drop from wedge mount, and impact is used normally.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of insulating tension clamp of avoiding wedge in use to occur inconsistent phenomenon.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of insulating tension clamp, and its innovative point is: mainly comprise wire clamp and wedge;
The U-bolt that described wire clamp mainly comprises pedestal and is connected with pedestal, described pedestal is trapezoidal shape, on the top of the less one end of the bore of pedestal, be provided with a circular hole hanger, one side of described pedestal has T shape cavity, make overall base be C word shape, outer surface in the side of not opening cavity of pedestal is provided with ring stiffener, the middle part of described ring stiffener is provided with a vertical reinforcement, in the both sides of the bottom of pedestal, be provided with the hanger that appearance U-bolt passes, described pedestal inserts wedge from the larger one end of bore;
Described wedge is spliced by two little wedges, described wedge entirety is trapezoidal shape, the structure of two little wedges is identical, the cross section of described little wedge becomes C type shape, a side at the tail end of little wedge is provided with a splicing projection, inwall at little wedge is evenly provided with unidirectional sawtooth along the long axis direction of little wedge, after two little wedge splicings, makes the middle part of overall wedge form a round table-like cavity;
On the outer surface of described two little wedges, be provided with a stopping means.
Further, described stopping means is specially: the tail end of a little wedge is provided with a positioning convex therein, between described positioning convex and splicing projection, form limited impression, in the relevant position of another little wedge, be provided with the spacing preiection matching with limited impression.
The utility model has the advantage of: by the use of stopping means, make two little wedges can be good at being fixed together, avoided two little wedges in use to occur the phenomenon misplacing, simultaneously when needing repairing, can also dismantle very easily, very convenient.
