Description
Technical field
The utility model relates to the test fixture in a kind of electric power apparatus manufacture process, relates in particular to the counter-bending testing fatigue performance of a kind of composite insulator frock.
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.Run into weather such as strong wind heavy snow through regular meeting; composite insulator can be subjected to bigger bending stress; composite insulator can be along with waving of electric wire crooked recovery the reciprocally; can cause composite insulator to reach stress limit in actual use and directly cause the fracture, also can be owing to alternating bending causes its fatigue failure.Therefore before a composite insulator of producing is being put into on-the-spot the utilization, need carry out bending resistance and anti-fatigue performance is test to it.Though what existing specialized automaticity was higher on the market carries out the device that bending resistance and anti-fatigue performance are test to composite insulator, this type of installs mostly complex structure, 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 counter-bending testing fatigue performance of composite insulator frock is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
The counter-bending testing fatigue performance of a kind of composite insulator frock is characterized in that: comprise a guide rail, described guide rail is by stent support;
Be with a guide pin bushing on the described guide rail, the fixedly connected travelling block in described guide pin bushing bottom; Also be provided with a fixed pulley on described support, be provided with a windlass below described fixed pulley, its end points was fixed on the described support after described windlass wire rope passed fixed pulley and travelling block successively;
Described guide pin bushing end face is provided with hole; Described support is provided with and the described guide pin bushing hole coaxial hole that is complementary;
Post a stress section at described wire rope;
On described support, also also be provided with a scale in parallel with the described guide rail outside; Described scale label is in its outside;
One indicator stem that is connected with guide pin bushing stretches out the described scale outside;
Also be provided with a photoelectric sensor in described scale inboard;
Also comprise a panel controller, described panel controller keeps communicating by letter with described stress section, photoelectric sensor and windlass; Also has data display screen on the described panel controller.
Further, also be connected with an indicator stem on the guide pin bushing, be convenient to read from described scale the position at guide pin bushing place.
Advantage of the present utility model is: simple and reasonable, it is comparatively convenient to use, and can test to the mechanical property (anti-bending strength, antifatigue failure performance) of composite insulator, thereby guarantee the quality of composite insulator.
Description of drawings
