Embodiment 1
[0028] Such as figure 1 , figure 2 Shown: a tool for replacing a suspension insulator with electricity, including a frame bracket and a telescopic suspension mechanism set on the top of the frame bracket; the frame bracket includes a bottom support plate and a top cross brace 4, The supporting plate and the cross brace are connected by two pairs of insulating connectors 6 with adjustable length.
[0029] Each pair of insulating connectors 6 includes two insulating pull plates 61. The insulating pull plates 61 are elongated insulating plate structures with a number of connecting through holes. The insulating pull plates 61 are placed in the through holes through bolts and used The screw cap is screwed to limit the connection, and the through-hole connection at different positions can be selected according to the needs to realize the length adjustment of the insulating connector; if the length is still not enough, the existing two insulating pull plates can also be connected b...
Embodiment 2
[0033] Such as figure 1 , figure 2 Shown: the difference between this embodiment and embodiment one is:
[0034] The adjusting lead screw 3 includes two sections of an upper lead screw 31 and a lower lead screw 32 fixedly connected with the self-locking hook 1 and the cross brace 4 respectively, and the upper lead screw 31 and the lower lead screw 32 are positive and negative screw structure, the upper lead screw 31 and the lower lead screw 32 are connected through a sleeve 33 with positive and negative screw threads on the inner wall, an adjustment handle 34 is arranged on the sleeve 33, and the top end of the upper lead screw 31 is connected to the The self-locking hook 1 is welded, and the lower end of the lower lead screw 32 is welded with the middle part of the cross brace 4 . By controlling the adjustment handle 34 to rotate the sleeve 33, the upper and lower screw screws can be rotated into the sleeve 33 at the same time, which can effectively improve the lifting eff...
Embodiment 3
[0037] A method for performing live replacement of hanging insulators of a hanging bottle string by using the above-mentioned tool, comprising the following steps:
[0038] 1) Preparation: The operator assembles the above-mentioned tools for live replacement of the suspension insulator in the local area, and reserves one side of the insulating connector 6 not to be installed;
[0039] 2) Hoisting: The tower operator boards the pole tower to the cross arm above the insulator to be replaced, and uses the transfer rope to transfer the tool for replacing the hanging insulator with power to the cross arm where the insulator is to be replaced. The cross arm operator uses the self-locking hook. The assembled live replacement suspension insulator tool is hung on the cross arm above the insulator to be replaced, and the insulating connector 6 on the side that has been installed is pushed by hand. Put the hammer into the supporting plate, and then connect the insulating connector 6 on t...
