The fixture disclosed by the utility model has simple structure, is convenient, rapid and safe to operate, is time-saving and labor-saving, has high construction efficiency and is particularly suitable for replacing the V-shaped double-string insulator of the compact 500kV power transmission line.
Description
Technical field
The utility model belongs to the ultra-high-tension power transmission line service kit, and what relate to is a kind of jig of changing insulator, particularly a kind of machete type jig that is used for the two insulator strings replacings of compact 500kV transmission line V-type.
Background technology
In the ultra-high-tension power transmission line maintenance, the replacing of insulator is a regular job, and the jig structure of changing insulator should be reasonable, must be suitable with the gold utensil in the circuit, could guarantee to change smoothly, and can be time saving and energy saving.At present, the compact 500kV transmission line in the Yunnan Province of China operation of power networks has 10, and its height above sea level is at 250-2800m; Hypsography along the line changes greatly; The steep paddy in slope is dark, and the tower position is more, and span is big, the discrepancy in elevation is big; Therefore, the shape of multiple gold utensil and existing 220kV and different in the tower in the circuit, conductor arrangement, insulator string assembly type and the circuit with line.Machete type jig is incompatible fully to be used in compact 500kV transmission line and existing pair of insulator string changed.
Summary of the invention
The purpose of the utility model is to propose a kind of two insulator strings of V-type that are adapted at using in the compact 500kV transmission line and changes machete type jig.
The technical scheme that realizes above-mentioned purpose is: the two insulator strings of a kind of compact 500kV transmission line V-type are changed machete type jig; Comprise before the big knife-edge card behind the card and big knife-edge and two ends be articulated in respectively before the retraction assemblies of card and back card tail end; Each parts of jig are on same plane, and said preceding card is identical with structure, the shape of back card, is tabular integrated member; Leading portion is the hook section; Back segment is the handle of a knife section, links up with the die cavity of Duan Youyi grafting line hardware yoke plate, and the line hardware yoke plate L-8445S of this die cavity and grafting is suitable.
Said die cavity be one along the plate face and perpendicular to the groove of hook face, the end face of groove is an inclined-plane, this inclined-plane forms an obtuse angle perpendicular to the plate face and with the hook section knife back.
Said retraction assemblies is connected to form by hydraulic pressure leading screw and insulation pull-rod.
During use, the front and rear card of jig is plugged on respectively on the two ends gold utensil yoke plate of duplex V-type twin insulator strings, the right angle link plate of hook companys of catching on gold utensil yoke plate is terminal, operates the replacing that retraction assemblies can be implemented one side bunch of insulator then.
The utility model jig is simple in structure, and easy to operate, quick, safety save time, laborsaving, and efficiency of construction is high, is particularly suitable for the replacing of the two insulator strings of compact 500kV transmission line V-type.

Among the figure: 1. card before, 2. back card, 3. hydraulic pressure leading screw, 4. insulation pull-rod, 5. groove, 6. groove end face, 7. line hardware right angle link plate, 8. line hardware L type yoke plate, 9. connecting screw rod, 10. line insulator string.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1,2, shown in 3, the utility model is made up of preceding card 1, back card 2, hydraulic pressure leading screw 3 and insulation pull-rod 4, preceding card 1 with after to block 2 structure, shape identical; All be the machete shape, be tabular integrated member, leading portion is the hook section; Back segment is the handle of a knife section; Hydraulic pressure leading screw 2 and insulation pull-rod 3 connect to form the retraction assemblies of jig, before the two ends of this retraction assemblies are hinged on respectively card 1 and back card 2 handle of a knife termination (as shown in Figure 1), each parts of jig are on same plane.Before the hook face interposition of card 1 and back card 2 hook sections be equipped with one along the plate face and perpendicular to the groove 5 (as shown in Figure 3) of hook face; The end of this groove 5 is that groove end face 6 is inclined-planes, and this inclined-plane forms obtuse angle (as shown in Figures 2 and 3) perpendicular to the plate face and with the knife back of linking up with section.
As shown in Figure 4; When changing line insulator string; Preceding card 1 and back card 2 are plugged on respectively on the two-termial line gold utensil L type yoke plate (L-8445S) 8 of duplex V-type insulator string, just one side of line hardware L type yoke plate 8 are inserted in the groove 5, the hook of preceding card 1 and back card 2 catches on the end of the line hardware right angle link plate (Z-84180S) 7 of connection line gold utensil L type yoke plate 8 respectively; Pretension hydraulic pressure leading screw 3; At this moment, preceding card 1 forms tight the contact with the groove end face 6 that block on 2 back with the inclined-plane of line hardware L type yoke plate 8, and two contact-making surfaces form supporting surfaces.Along with hydraulic pressure leading screw 3 continue tighten up; Groove end face 6 compressing line hardware L type yoke plates 8 inclined-planes make line hardware L type yoke plate 8 rotate around its connecting screw rod that is connected with line hardware right angle link plate 79, and promptly line hardware L type yoke plate 8 deflects; Thereupon; On one side line insulator string 10 is able to off-load and produces the free gap, when its free gap reaches when unloading string and requiring, can implement the replacing of bunch of insulator on one side.
When changing the another side insulator string, the switching-over of the utility model jig is connected to the another side of line hardware, implements aforesaid operations and get final product.
