As the one side of the embodiment of the present invention, the present embodiment provides a kind of replacing card of straight line duplex V insulator strings
Tool, it is a kind of structural representation of the replacing fixture of straight line duplex V insulator strings of the embodiment of the present invention with reference to figure 1, including：Close
1, two screw mandrel 2 of formula card, machete card 3 and revotating card 4.
Wherein, the both ends of closed fixture 1 connect same one end of two screw mandrels 2 respectively, and the other end of two screw mandrels 2 connects respectively
The both ends of revotating card 4；The center bottom of revotating card 4 is connected with the top of machete card 3, and enables revotating card 4 relative with machete card 3
Rotate；The tail end of machete card 3 is provided with the fixed hook 301 of connection triangle yoke plate 5, in fixed hook 301 and rotation on machete card 3
The fulcrum pin axis hole 302 perpendicular to the card face of machete card 3 is provided between card 4 and the tie point of machete card 3.
One of embodiment, right angle hanging plate 501 is installed on triangle yoke plate 5, machete card 3 is hung by fixed hook 301
It is connected on right angle hanging plate 501.Pivot bolt is installed in fulcrum pin axis hole 302, passes through the fulcrum using the slope of triangle yoke plate 5
Bolt can be by the clip of machete card 3 on triangle yoke plate 5.
Specifically, the present embodiment is that machete card 3 uses titanium alloy, and pivot bolt uses SiMn materials, other uses
LC4 materials, the work load 7.5T of machete card 3.Weight is no more than 10kg.Revotating card 4 uses titanium alloy, above machete card 3,
Operating personnel can operate on gold utensil, it is possible to reduce livewire work risk.The weight of revotating card 4 is no more than 10kg.Screw mandrel 2, which uses, to be added
Two sets of strong type screw mandrel, live load 6T.Closed fixture 1 uses titanium alloy, and weight is no more than 10kg.
On the clip of machete card 3 to triangle yoke plate 5, apex yoke plate hole will be selected on triangle yoke plate 5 as the first stress
Point, right angle hanging plate 501 is installed in the first stress point, machete card 3 is articulated in into right angle by the fixed hook 301 of machete card 3 hangs
On plate 501.Pivot bolt is installed in fulcrum pin axis hole 302 on machete card 3, the card holder of machete card 3 existed by pivot bolt
On the slope of triangle yoke plate 5, the slope of triangle yoke plate 5 and the application point of the pivot bolt on machete card 3 are fulcrum, with machete card
3 and the tie point of revotating card 4 are the second stress point, machete card 3 is reached equalising torque.
The both ends of revotating card 4 connect same one end of two screw mandrels 2 respectively, and the other end of two screw mandrels 2, which is connected to, to be closed
The both ends of formula card 1, the clip of closed fixture 1 on the steel cap of insulator, when tightening up screw mandrel 2, pass through two silks in straight line duplex V strings
Bar 2, by the load transfer on insulator chain to revotating card 4, then pass through by revotating card 4 tie point of revotating card 4 and machete card 3
By on the second stress point of load transfer to machete card 3.Make the effect no longer loaded of straight line duplex V strings, so as to convenience more
The insulator and gold utensil changed in straight line duplex V strings.
When the clip direction of closed fixture 1 and machete card 3 be not in a plane, revotating card 4 is rotated, makes revotating card 4, two
