Description
Technical field
The utility model relates to a kind of high-voltage electric power circuit tools for live working, relates in particular to a kind of charged for replacement 110kV pre-twisted line hardware strain insulator jig.
Background technology
In recent years, according to country's " amphitypy three is new " (resource-conserving, environmentally friendly, new technology, new material, new technology) needs built, on the newly-built 110kV transmission line of some unit parts, conventional bolt-type strain clamp and the compression type strain clamp using substituted by new material pre-hinged strain clamp.And pre-hinged strain clamp is compared with bolt-type strain clamp or compression type strain clamp in shape and is all had larger difference, cause originally can charged for replacement 110kV strain insulator list insulator string General-purpose wing type clamp apparatus cannot on the single insulator string with pre-hinged strain clamp, use, even if adopt conventional Lever Blocks, the replacing that has a power failure of chain block or double-hook wire grip, also can be because matching used fixing-line device cannot fix on the preformed armor rods of wire or strain clamp can not stringing lead, finally cause and cannot successfully change this and be arranged on the strain insulator list insulator string on 110kV pre-hinged strain clamp.If the wing shaped clamp of prior art does not structurally upgrade, will make the work of charged for replacement the above-mentioned type list string strain insulator to carry out, bring larger potential safety hazard to the safe and stable operation of circuit.
Summary of the invention
In view of the problems referred to above of prior art, the purpose of this utility model is to provide a kind of charged for replacement 110kV pre-twisted line hardware strain insulator jig easy to use, quick for installation.
To achieve these goals, the utility model provides a kind of charged for replacement 110kV pre-twisted line hardware strain insulator jig, comprise front end card, rear end card, both sides insulation pulling plate and bottle-holding rack, it is characterized in that: the draw-in groove of described front end card is semi-circular asymmetric notch, matches with the overall dimension of thimble in pre-hinged strain clamp.
In order to make the utility model have larger expansion in the scope of application, meet the requirement that different strain insulators connect gold utensil type of attachment, further scheme is that rear end card is designed to open type square groove and clamping plate fit structure, connects gold utensil in order to fixing strain insulator.
Front end card core of the present utility model position is strictly according to the configuration design of pre-hinged strain clamp, compared with the ∏ type structure generally adopting with existing General-purpose wing type clamp apparatus, the semi-circular asymmetric groove structure of design can be well with pre-hinged strain clamp in the overall dimension of thimble match, and the steady and stressed equilibrium that keeps wing type clamp apparatus, overcome the problem of General-purpose wing type clamp apparatus unstable and unequal force in application.Wing type clamp apparatus front end card latch is fixed on the thimble in pre-hinged strain clamp, and stress point in the same horizontal line, can effectively ensure the stressed at equilibrium of a whole set of jig.Rear end card is designed to the fixing strain insulator of open type square groove clamping plate and connects gold utensil, guarantees that it can meet the requirement that different strain insulators connect gold utensil type of attachment, has larger expansion in the scope of application compared with other products.
The beneficial effects of the utility model are, the semi-circular asymmetric groove structural design of front end card, the gap that can farthest meet the thimble in jig and pre-hinged strain clamp reaches minimum requirement, overcome General-purpose wing type clamp apparatus because of the do not coexist problem of the unstable and unequal force producing in application of contour structures, met live line working personnel and operated to light and flexible at the scene.
Brief description of the drawings
Fig. 1 is the example structure schematic diagram of charged for replacement 110kV pre-twisted line hardware strain insulator jig of the present utility model;
Fig. 2 is the structural representation of front end card in the utility model;
Fig. 3 is the structural representation of rear end card in the utility model.
Embodiment
Below in conjunction with example and contrast accompanying drawing the utility model is described in further detail.
As shown in Figure 1, charged for replacement 110kV pre-twisted line hardware strain insulator jig of the present utility model, comprises front end card 8, rear end card 1, adjustable screw 3, both sides insulation pulling plate 4, insulating insulator bracket 6 parts such as grade.
Strain clamp adopts airfoil structure, material selection aluminum alloy materials, and the design of wing type clamp apparatus will meet the maximum load requirement of tension-resistant rod.Before wing type clamp apparatus, card mates with the form factors of preformed armor rods gold utensil, and gap length meets operating personnel and operates light and flexible; After wing type clamp apparatus, card can meet the assembling form that different strain insulators connect gold utensil.
In the time needing charged for replacement that the strain insulator list insulator string of pre-hinged strain clamp is installed, only the parts such as the front end card of this wing shaped clamp 8 and rear end card 1, adjustable screw 3, both sides insulation pulling plate 4 and insulating insulator bracket 6 need be assembled and put in place on request.
The shape at core position and the profile of pre-hinged strain clamp of front end card 8 are consistent, for the overall dimension of the thimble in pre-hinged strain clamp and the draw-in groove of front end card 8 are matched, keep the steady and stressed equilibrium of wing type clamp apparatus, front end card 8 middle parts are designed to semi-circular asymmetric groove 81, as shown in Figure 2.The semi-circular asymmetric groove 81 at front end card 8 middle parts is inserted on the thimble 7 in pre-hinged strain clamp, the force-bearing pin 82 at front end card 8 middle parts is inserted in the thimble of pre-hinged strain clamp, and force-bearing pin is locked.Force-bearing pin is designed to the chromium metal cylinder of Ф 22mm-40Cr, can meet carrying tension, can play well the effect of balance wing type clamp apparatus stability simultaneously.Rear end card is designed with open type square groove 12, coordinates with clamping plate 11, and clamping plate 11 can move along square groove 12.Turn on the butterfly bolt 13 of rear end card 1 intermediate openings formula square groove clamping plate and insert to extend and encircle 2, screwing butterfly bolt and be fixed.Install bottle-holding rack 6, the temporary transient weight that supports strain insulator 5 during for capable of live-line replacing strain single insulator.Tighten up adjustable screw 3, make strain insulator 5 in relaxed state, after jig stressing conditions is good, transfer to the spring catch in the last a slice strain insulator 5 of side of wire was, just can change smoothly strain insulator.
