Description
Technical field
The utility model design power equipment detects the frock field, especially designs the antitorque test fixture of a kind of composite insulator.
Background technology
Along with the rapid increase of electricity needs, need to build large-scale power delivery networks and meet the demands.Composite insulator is widely used in the power transmission line, is used for improving stability and security in the electric power course of conveying.Composite insulator is a kind of long clavate puncture-proof composite insulator.But the condition of work of composite insulator in electrical network is comparatively abominable.Composite insulator can be along with waving of electric wire be subject to larger tangential force in practical work process, often has the composite insulator torsional failure and cause larger accident in electrical network.This need to test its anti-torsion performance before the composite insulator of producing is being put into on-the-spot the utilization.Although the higher device that composite insulator is carried out torsion test of existing specialized automaticity on the market, such device is complex structure mostly, and is with high costs.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of simple and reasonable, the easy to use antitorque test fixture of composite insulator is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
The antitorque test fixture of a kind of composite insulator is characterized in that: comprise a column, be provided with fastening boss at described column; Be shaped with half slot on the described fastening boss;
Comprise that also one is shaped with and the be complementary friction top of half slot of described boss half slot, removably connect by bolt between described fastening boss and the friction top;
Also be provided with positive stop lug boss on described column, be shaped with the guiding half slot on the described positive stop lug boss, described guiding half slot is coaxial with the boss half slot; Comprise that also one is shaped with and the be complementary spacing cover plate of half slot of described guiding half slot, be connected by bolt is detachable between described positive stop lug boss and the spacing cover plate;
Also comprise a movable fastener, described movable fastener is the anchor ear sheet that two halves are flexibly connected by bolt; Wherein an anchor ear sheet also is connected with torsion plate, and described torsion plate lower end has the torsion hole of closing tight rear endoporus same axis with described two anchor ear sheets;
Also comprise a torque-indicating wrench, described torque-indicating wrench torsion joint is fastened in the described torsion plate torsion hole.
Further, above being positioned at described torque-indicating wrench, around column, be provided with netted guardrail.
Further, it is characterized in that: described torsion hole is inner hexagonal hole.
The utility model is simple and reasonable, and it is very convenient to use, thereby can reflect the torsional property that torsion is known composite insulator from the torsion registration of torque-indicating wrench, has stronger practicality.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1,2 and 3, the utility model comprises a column 1, is provided with fastening boss 1a at described column 1; Be shaped with half slot 1a1 on the described fastening boss 1a; Comprise that also one is shaped with the be complementary friction top 2 of half slot with described boss half slot 1a1, removably connect by bolt between described fastening boss 1a and the friction top 2; Also be provided with positive stop lug boss 1b on described column 1, be shaped with guiding half slot 1b1 on the described positive stop lug boss 1b, described guiding half slot is coaxial with the boss half slot; Comprise that also one is shaped with the be complementary spacing cover plate 3 of half slot with described guiding half slot 1b1, be connected by bolt is detachable between described positive stop lug boss 1b and the spacing cover plate 3; Also comprise a movable fastener, described movable fastener is the anchor ear sheet 4 and 5 that two halves are flexibly connected by bolt; Wherein an anchor ear sheet 5 bottoms also are connected with torsion plate 6, and described torsion plate 6 lower ends have the torsion hole 6a that closes tight rear endoporus same axis with described two anchor ear sheets; Also comprise a torque-indicating wrench 7, described torque-indicating wrench 7 torsion joints are fastened in the described torsion plate torsion hole 6a.For the sake of security, above being positioned at described torque-indicating wrench 7, around column 1, be provided with netted guardrail; Because most of torque spanner connector all is hexangle type, described torsion hole 6a is inner hexagonal hole.
Concrete use flow process of the present utility model is as follows: will need first coupling part, the top 8a of the composite insulator 8 tested to be pressed abd fixed on and compress on the boss 1a; Again its bottom coupling part 8b is clamped by two halves anchor ear sheet 4 and 5; Composite insulator 8 bottoms need to pass positive stop lug boss 1b and the spacing cover plate 3 formed spacing holes on the column 1 simultaneously, and this moment, composite insulator 8 did not have limited cover plate 3 to be pressed on the positive stop lug boss 1b, can rotate with respect to spacing hole; One torsion plate 6 is connected to half anchor ear sheet, 5 bottoms and extends to the below of composite insulator 8, and has the interior hexagonal torsion hole 6a coaxial with the half slot 1b1 that leads at described torsion plate 6, and torque-indicating wrench 7 connectors are fastened in the described torsion hole 6a; Then rotate 7 pairs of composite insulators of torque-indicating wrench 8 and carry out the torsional property test.Wherein the effect of positive stop lug boss 1b and spacing cover plate 3 is to guarantee that composite insulator 8 does not produce bending in twist process, it is carried out spacing, guarantees the accuracy of testing.
The utility model is simple and reasonable, and it is very convenient to use, thereby can reflect the torsional property that torsion is known composite insulator from the torsion registration of torque-indicating wrench, has stronger practicality.
