It is sheathed on described first bolt；Right side wire clamp lower end is hinged with a moving block, and described moving block offers tapped through hole, and
It is equipped with the second bolt, left side wire clamp lower end is provided with a bayonet socket, described second bolt left end is provided with the head that bayonet socket is stated in cocker residence
Portion, described first bolt, the second bolt right-hand member are respectively equipped with locking nut.
Further, wire clamp upper end in left side is articulated with described support through bearing pin, so that left side wire clamp can be around described bearing pin
Swing.
Further, described support is provided with the action bars connecting portion for attended operation bar.
The invention also discloses the installation method of above-mentioned shunting wire clamp device, comprise the following steps：
（1）First action bars is connected with described action bars connecting portion, by the first action bars by shunting wire clamp device
It is delivered at heat generating spot；
（2）Described left side wire clamp is turned to by the position that the second bolt is stated in cocker residence using the second action bars；
（3）Described second bolt is pulled so as to head blocks the bayonet socket of described left side wire clamp using the second action bars, thus
Shunting wire clamp device is packed into the wire at heat generating spot；
（4）Spanner set using the second operation club head screws locking nut, thus fixing shunting wire clamp device, so far
Shunting wire clamp device installation.
The invention has the beneficial effects as follows providing a kind of ground potential installing type shunting wire clamp device and its installation method, can be real
Ground potential adopts action bars and aid Remote Installation shunting wire clamp now, compared to traditional equipotential installation method and dress
Put, one is that of avoiding equipotential live line work personnel turnover high voltage electric field, then adopts earth potential working mode, and operating personnel is in shaft tower
Cross-arm or tower body is operable, at utmost ensure that the safety of operating personnel, prevented installation shunting wire clamp it may happen that
Electric shock accidents, two is to solve the problems, such as in equipotential live line work firmly terraced decorating position and support staff's occupy-place, expands ground electricity
The optional scope of bit manipulation personnel's occupy-place, decreases the operation that cannot install because safe distance is not enough, expands the scope of application, and three
It is the reduction of high pressure equipotential live line work personnel and sets up the insulation program such as ladder firmly, simplify installation procedure so that shunting wire clamp
Assembly and disassembly operation is simpler, efficient, has very strong practicality.
