Abstract
The invention relates to a device for hoisting a V-shaped insulator string, in particular to a V-shaped insulator string suspension device for vibration test of the V-shaped insulator string, which comprises an electric block, V-shaped insulator strings and a V-shaped insulator string assembling fitting, wherein the electric block comprises hoist cranes and a position adjusting block, the V-shaped insulator string assembling fitting is provided with two V-shaped insulator strings, one end of each V-shaped insulator string is hinged onto the V-shaped insulator string assembling fitting, the other end of each V-shaped insulator string is respectively connected with the hoist cranes, the two hoist cranes are symmetrically arranged onto an iron tower upper beam, the hoist cranes are also respectively connected with the position adjusting block, and the iron tower upper beam is parallel to the ground and is used for suspending the V-shaped insulator strings and adjusting an angle between the two insulator strings, so the defect of a suspension method of the V-shaped insulator in an ordinary laboratory can be overcome.
Description
Technical field:
The present invention relates to the device for the lifting of " V " type insulator, more specifically relate to a kind of " V " type insulator string suspension device for " V " type insulator string vibration test.
Background technology:
In high voltage power transmission and transforming field, insulator string is for connecting overhead transmission line and steel tower, and plays insulating effect between.Along with the progressively raising of transmission line electric pressure, the string of insulator string is long also progressively to be lengthened, and serial type is then divided into conventional linear string, strain insulator-string, and prevents the V-type string of overhead transmission line windage yaw.At the line design initial stage, need in laboratory to the insulator of different serial type do power frequency or direct current wet resistance test, lightning impulse does resistance test, switching impulse wets resistance test, corona and the related electric such as radio interference test, Vibration Creep and mechanical test.This just needs the insulator string under lab arranging different serial type.
The suspention of laboratory " V " type insulator and assembling are comparatively complicated, conventional suspension system uses one or two electric block vertically suspended in midair to hang a steel cross-arm, hang on cross-arm by two ends of " V " type insulator string, the position of two hitch points needs to calculate according to the string of insulator angle that is long and two insulator strings.Shortcoming be automaticity low, bear alternate load ability, rigidity is little, useful life is short;
Summary of the invention:
One provided by the invention " V " type insulator string suspension device, for the suspention of " V " type insulator string and the adjustment of two insulator string angles, comprise steel tower and two cover electric blocks, often overlap electric block by a hoist crane and a position adjustment cucurbit composition, solve the deficiency of the suspension system of Routine Test Lab " V " type insulator.
For achieving the above object, the present invention is by the following technical solutions:
One provided by the invention " V " type insulator string suspension device, comprise electric block, " V " type insulator string and " V " type insulator string assembling gold utensil, described electric block comprises hoist crane and position adjustment cucurbit, described " V " type insulator string assembling gold utensil is provided with two " V " type insulator strings, one end of described two " V " type insulator strings is all hinged on " V " type insulator string assembling gold utensil, the other end of described two " V " type insulator strings is connected to hoist crane, described two hoist cranes are symmetricly set on steel tower upper beam, described hoist crane also adjusts cucurbit with position and is connected, described steel tower upper beam is parallel to ground.
In one provided by the invention " V " type insulator string suspension device technical scheme, described position adjustment cucurbit is symmetricly set on the two ends of steel tower upper beam, and is connected with hoist crane by steel wire rope.
In another preferred a kind of " V " type insulator string suspension device technical scheme provided by the invention, described position adjustment cucurbit is driven by stepless time adjustment motor.
Owing to have employed technique scheme, the beneficial effect that the present invention obtains is:
1, two cover electric blocks can synchronous hoisting weight, according to test requirements document lifting V-type insulator test product;
2, two cover electric hooks all can bear 5 tons of oblique pullings, and stepless changing V-type string two hanging point distance, meet the V-type string test of different angle, automaticity improves greatly;
3, hoist crane can realize oblique suspension insulator string, breaches the restriction that conventional electric block only allows vertical suspension heavy weight;
4, well bear alternate load ability, meet insulator vibration test;
5, large rigidity design, longer than the conventional cranes life-span.
