Portion is connected by rotating shaft with drive link one end, and the drive link other end is fixed on plug-in strip by rotating shaft, the power
Interlinking lever end is connected by the expansion link of rotating shaft and telescoping mechanism, and the telescoping mechanism is fixed in fixed seat by rotating shaft.
The power interface and controller of the telescoping mechanism extend to electric pole bottom by cable.
The power interface and controller are arranged on the electric pole at the 2.8-3.5m of ground, the controller output
Controller signals are to telescoping mechanism, and the power interface connects power supply and is that controller and telescoping mechanism are powered.
The power interface is rain-proof plug.
The dynamic link stroke two ends are equipped with travel switch, and the travel switch exports break signal to controller.
The telescoping mechanism is hydraulic cylinder.
Described drive shaft one end is provided with rotating handles.
The drive link is insulating bar.
The plug-in strip and junction block are engaged provided with three groups, and plug-in strip and junction block described in every group are equipped with one and plug-in strip
The plectrum and drive link of cooperation.
It is easy to use the utility model has the advantage of simple in construction, not only it is effectively reduced the labor that operating personnel step on bar
Fatigue resistance, can also reduce the security risk for operation of ascending a height.
Brief description of the drawings
