Abstract
The invention relates to a single-string-insulator maintenance device which includes a positioning device, an adjustment device and an insulator positioning-limiting tray. The positioning device includes a U-shaped clamp, a spacing clamping plate adaptive with the U-shaped clamp, an extension rod fixedly arranged at the lower end of the U-shaped clamp, an adaptor fixedly arranged at the lower end of the extension rod and a first adjustment screw rod fixedly arranged on the first adopter, wherein an end part of the first adjustment screw rod is provided with a first position-limiting snap ring. Through a lap-joint structure, the single-string-insulator maintenance device is capable of satisfying insulators of different models and even if an insulator is installed at a position comparatively close to the edge and incapable of being fixed directly, the single-string-insulator maintenance device can also use the adaptor for three-dimension fixing and a safety device is also added at a connection position so that once an extreme position is reached through rotation, continuing of rotation is impossible and thus the safety of work personal is ensured. The single-string-insulator maintenance device is simple in structure, low in cost, capable of live line work and capable of improving safety coefficient and work efficiency of the work personal significantly.
