The invention has the beneficial effects as follows：The service kit for changing insulator chain of the present invention, left card main body and right card
Main body can be fastened on the steel cap of certain insulator in insulator chain, and then drive screw assembly rotates, and is drawn using screw component
The tightly left card main body and right card main body tension force to overcome insulator chain to be subject to, then can be utilized existing dismantling device will be located at
Insulation minor segment between left and right card main body is removed, and replaces with new insulator chain, the left and right card main body of this replacing fixture
For split-type structural, the bayonet socket with insulator steel cap cooperation can be formed after left and right card body combination, insulator can be fastened in
On the steel cap of any one insulator in string, from any insulator chain sections can be changed using this fixture, changing insulator
During string, old insulator chain can support and is fixed on the first bracing frame inside pull bar, and new insulator chain can support and consolidates
Due on the second bracing frame outside pull bar, after old insulator chain sections is pulled down from insulator chain, the first bracing frame
With the second bracing frame around pull rod shaft line locking rotate 180 °, rotate finish after, pull the first bracing frame and the second bracing frame around
Connecting rod axis rotates, and so that the insulator chain being suspended in below bracing frame is overturn to above bracing frame, then installs positioning lever lock
Determine the rotation around connecting rod for the bracing frame, finally new insulator chain is installed to specified location.
Brief description
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention.
