Description
Technical field
The present invention designs power equipment and detects frock field, especially designs the antitorque test fixture of a kind of composite insulator.
Background technology
Along with the sharply increase of electricity needs, need to build large-scale power delivery networks and meet the demands.Composite insulator is widely used in power transmission line, is used for improving stability and security in 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 severe.Composite insulator can be along with waving of electric wire is subject to larger tangential force in practical work process, often has composite insulator torsional failure and cause larger accident in electrical network.This,, before the composite insulator of producing is being put into on-the-spot utilization, need to test its anti-torsion performance.Although the existing higher device that composite insulator is carried out to torsion test of specialized automaticity on market, such device is complex structure mostly, with high costs.
Summary of the invention
Object of the present invention 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 invention is as follows:
The antitorque test fixture of composite insulator, is characterized in that: comprise a column, be provided with fastening boss on described column; On described fastening boss, be shaped with half slot;
Also comprise that one is shaped with and the match friction top of half slot of described boss half slot, between described fastening boss and friction top, by bolt, removably connect;
On described column, be also provided with positive stop lug boss, be shaped with guiding half slot on described positive stop lug boss, described guiding half slot is coaxial with boss half slot; Also comprise that one is shaped with and the match spacing cover plate of half slot of described guiding half slot, between described positive stop lug boss and spacing cover plate, by bolt is detachable, be connected;
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 is also 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 described torsion rod torsion hole.
Further, above being positioned at described torque-indicating wrench, along column, be provided with netted guardrail around.
Further, it is characterized in that: described torsion hole is inner hexagonal hole.
The present invention 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.
Accompanying drawing explanation
Fig. 1 is that the present invention uses view.
Fig. 2 is pillar construction schematic diagram of the present invention.
Fig. 3 is the present invention's half anchor ear sheet and torsion plate structural representation.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Shown in Fig. 1,2 and 3, the present invention includes a column 1, on described column 1, be provided with fastening boss 1a; On described fastening boss 1a, be shaped with half slot 1a1; Also comprise that one is shaped with the match friction top 2 of half slot with described boss half slot 1a1, between described fastening boss 1a and friction top 2, by bolt, removably connect; On described column 1, be also provided with positive stop lug boss 1b, be shaped with guiding half slot 1b1 on described positive stop lug boss 1b, described guiding half slot is coaxial with boss half slot; Also comprise that one is shaped with the match spacing cover plate 3 of half slot with described guiding half slot 1b1, between described positive stop lug boss 1b and spacing cover plate 3, by bolt is detachable, be connected; 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 anchor ear sheet 5 bottoms are also 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 described torsion plate torsion hole 6a.For the sake of security, above being positioned at described torque-indicating wrench 7, along column 1, be provided with netted guardrail around; Because most of torque spanner connector is all hexangle type, described torsion hole 6a is inner hexagonal hole.
Concrete use flow process of the present invention is as follows: first coupling part, the top 8a of the composite insulator 8 of needs test is pressed abd fixed on and is compressed on boss 1a; Again its bottom coupling part 8b is clamped by two halves anchor ear sheet 4 and 5; Composite insulator 8 bottoms need through the positive stop lug boss 1b on column 1 and the formed spacing hole of spacing cover plate 3 simultaneously, and now composite insulator 8 does not have limited cover plate 3 to be pressed on positive stop lug boss 1b above, 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 on described torsion plate 6, has the interior hexagonal torsion hole 6a coaxial with the half slot 1b1 that leads, and torque-indicating wrench 7 connectors are fastened in described torsion hole 6a; Then rotate 7 pairs of composite insulators of torque-indicating wrench 8 and carry out 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, guarantee test accuracy.
The present invention 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.
