Description
Technical field:
The utility model relates to the device that is used for the lifting of " V " type insulator, more specifically relates to " V " type insulator string suspension apparatus of " V " type insulator string vibration test of a kind of being used for.
Background technology:
In the high voltage power transmission and transforming field, insulator string is to be used to connect overhead transmission line and iron tower, and between the two, plays insulating effect.Along with the progressively raising of transmission line electric pressure, the string of insulator string is long also progressively to extend, and serial type then is divided into conventional straight line string, strain insulator-string, and the V-type string that prevents the overhead transmission line windage yaw.In the circuit design initial, need be in the laboratory to the insulator of different serial types do power frequency or the wet resistance test of direct current, lightning impulse is done resistance test, switching impulse wet resistance test, corona and related electric and mechanical tests such as radio interference test, vibration creep.This just need under lab arrange the insulator string of different serial types.
The suspention of laboratory " V " type insulator and assembling are comparatively complicated; Conventional suspention method is to use steel cross-arm of electric block suspension of one or two vertical suspention; Two ends of " V " type insulator string are hung on the cross-arm, and the position of two hitch points need be calculated according to the string of insulator angles long and two insulator strings.Shortcoming be automaticity low, bear the alternate load ability, rigidity is little, useful life is short;
Summary of the invention:
A kind of " V " type insulator string suspension apparatus that the utility model provides; Be used for the suspention of " V " type insulator string and the adjustment of two insulator string angles; Comprise iron tower and two cover electric blocks; Every cover electric block is formed by a hoist crane and a position adjustment cucurbit, solves the deficiency of the suspention method of Routine Test Lab " V " type insulator.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of " V " type insulator string suspension apparatus that the utility model provides; Comprise that the assembling of " V " type insulator string and " V " type insulator string uses gold utensil; The assembling of said " V " type insulator string is provided with two " V " type insulator strings with gold utensil; One end of said two " V " type insulator strings all is hinged on the assembling of " V " type insulator string with on the gold utensil, and bolt is arranged, and the other end of said two " V " type insulator strings is connected with hoist crane respectively; Said two hoist cranes are symmetricly set on the iron tower upper beam, and said hoist crane also is connected with position adjustment cucurbit.
In another preferably a kind of " V " type insulator string suspension apparatus technical scheme that the utility model provides, said position adjustment cucurbit is through the stepless time adjustment motor-driven.
Because the beneficial effect that has adopted technique scheme, the utility model to obtain is:
1, two overlap electric blocks hoisting heavy synchronously, according to test requirements document lifting V-type insulator test product;
2, the electronic hook of two covers all can bear 5 tons of oblique pullings, and stepless adjustment V-type string two hanging point distances, satisfies the V-type string test of different angles, and automaticity improves greatly;
3, hoist crane can be realized oblique suspension insulator string, has broken through the restriction that conventional electric block only allows vertical suspension heavy weight;
4, the good alternate load ability of bearing satisfies the insulator vibration test;
5, big rigidity Design is longer than the conventional crane life-span.
