[background technology]
Known, insulator is a kind of special insulation control, can play support wire and prevent that electric current from returning the important function on ground in overhead transmission line.Aforementioned two effects must be guaranteed, and insulator should be because environment and the electric loading condition various dynamo-electric stress that causes that changes lose efficacy, otherwise insulator just can not produce great effect, will damage use and the service life of whole piece circuit.Because insulator is that glass or pottery are made mostly, be subject to environmental impact, after long-time the use, floating dust, birds droppings and other filth can appear, adhere at insulator surface in order to prevent the filths such as floating dust, the formation path is insulated sub-both end voltage and punctures, so want cleaned at regular intervals and change damaged insulator for insulator; Need to tighten up insulator string during the two insulator string of charged for replacement, conventional more difficult the completing of instrument.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses the two insulator string jigs of a kind of transmission line transposing, the utility model is by the Rational structure of screw rod, connecting plate, connecting rod A and connecting rod B, can realize tightening up fast of " V " shape insulator string, facilitate the replacing of damaged insulator.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
The two insulator string jigs of a kind of transmission line transposing, comprise hook A, upper hook B, connecting rod A, connecting rod B, connecting plate, setscrew nut, screw rod and lower draw-bar, the lower end of connecting rod A, connecting rod B is connected with the both sides of connecting plate and is locked by setscrew nut respectively, described connecting rod A, the V-shaped distribution of connecting rod B, the upper end of connecting rod A, connecting rod B be respectively equipped with link up with B, on link up with A; Be provided with lower draw-bar in the screw rod lower end, described screw rod middle part is connected with the middle part of connecting plate, is provided with adjusting nut on the screw rod on connecting plate top.
The two insulator string jigs of described transmission line transposing are provided with tube connector in the bottom of upper hook A, and connecting rod B upper end is in described tube connector.
The two insulator string jigs of described transmission line transposing are provided with tube connector in the bottom of upper hook B, and connecting rod A upper end is in described tube connector.
The two insulator string jigs of described transmission line transposing, described connecting plate middle part is dull and stereotyped, be respectively equipped with downward-sloping extension board in the both sides of middle part flat board, the lower end of connecting rod A, connecting rod B connects respectively the extension board of dull and stereotyped both sides, middle part, is connected with the middle part of connecting plate is dull and stereotyped in the middle part of screw rod.
The two insulator string jigs of described transmission line transposing, screw rod lower end are in the tube connector on lower draw-bar top, are respectively equipped with locking nut on the screw rod at two ends, tube connector up and down.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
The two insulator string jigs of transmission line transposing described in the utility model, " Y " shape structure of using screw rod, connecting plate, connecting rod A and connecting rod B to form, catch on the hitch point of " V " shape insulator string upper end by upper hook A and upper hook B, by adjusting nut, " V " shape insulator string is tightened up; The utility model has simple in structure with respect to existing operating type, the easy to operate beneficial effect of Denging.
