Description
Technical field
The invention belongs to the jockey of high-tension electricity circuit gold utensil, the suspension insulator anticreep chapeau de fer that specifically a kind of confession is connected with the pin ball of high-tension electricity circuit gold utensil.
Background technology
For the bulb that prevents pin ball comes off, be provided with the anti-drop device that W formula night bolt or R formula night bolt by stainless steel band steel pressure-type structure constitute in the existing suspension insulator chapeau de fer from the cap nest of suspension insulator chapeau de fer.When the cap nest of pin ball and suspension insulator chapeau de fer is in plumbness or inclination angle when little, under the effect of gravity and night bolt coupling mechanism force, the bulb of pin ball is difficult to come off from the cap nest of chapeau de fer body.But because the high-tension electricity circuit is in the open-air very abominable natural environment for a long time, under the alternation effect of big wind-force such as hurricane, can be because of 1) facade that the impact friction makes night bolt constantly takes place and seriously wears away to break and take off in the bulb of pin ball and the facade of night bolt, causes the bulb of pin ball to be deviate from from the inverted T shape groove of cap nest; Or because of 2) the huge longitudinal frictional force that produces in swing or when mobile of the bulb of pin ball makes the gib head distortion or the fracture of night bolt, causes the bulb of pin ball to be deviate from from the inverted T shape groove of cap nest.Also may lose restriction because of the material forfeiture elasticity of night bolt, cause bulb from the inverted T shape groove of cap nest, to be deviate from bulb.In a word, because existing night bolt is structural unreasonable, the security incident that can cause the bulb of pin ball to be deviate from from the cap nest of chapeau de fer body takes place, and then high-tension line is suffered heavy losses.
Summary of the invention
The objective of the invention is provides a kind of suspension insulator anticreep chapeau de fer of simple in structure, easy to disassembly and maintenance, good anti-drop effect in order to overcome above-mentioned deficiency.
The present invention includes the chapeau de fer body that is provided with jack and inverted T shape groove, wherein, jack is communicated with an end of inverted T shape groove, it is characterized in that also comprising that an end is provided with the anticreep backing plate of draw-in groove, anticreep buting iron that constitutes by base plate and the riser that is connected with the base plate upside and the bolt that is used to connect anticreep backing plate and anticreep buting iron, wherein, one end of anticreep backing plate and base plate is respectively equipped with the bolt hole with core, the other end of said anticreep backing plate and riser lay respectively in the jack of said chapeau de fer body and the notch end of inverted T shape groove, said bolt is positioned at the bolt hole of said anticreep backing plate and base plate, and said chapeau de fer body is provided with the boss that matches with said draw-in groove.
Also be provided with the screw retention plate that has through hole between described bolt and the anticreep buting iron, wherein, the two ends of said screw retention plate are respectively equipped with the nut button and oppositely detain, and said bolt is positioned at said through hole.
Also be provided with split pin in the said technical scheme, the other end of said anticreep backing plate is provided with for the pin-and-hole that inserts said split pin.
Said anticreep buting iron is the inverted T-shaped that matches with the notch of said inverted T shape groove.
Chapeau de fer body of the present invention has only carried out changing (only setting up boss at the notch end of inverted T shape groove) to existing chapeau de fer main body structure lessly, and do not relate to the structure that changes existing pin ball, can not only reduce investment cost to greatest extent, reduce and make and assembly cost, and can keep the premium properties of original structure.Anti-drop device adopts anticreep backing plate, anticreep buting iron and bolt, match with boss on the chapeau de fer body by the draw-in groove on the anticreep backing plate, not only can overcome original night bolt easily by mortality defectives such as mill (breaking) damage, distortion and forfeiture elasticity, but also can greatly improve the security reliability and the durability of use.Has advantage simple in structure, easy to disassembly and maintenance, good anti-drop effect.
