Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power transmission line maintenance, in particular to a tool for replacing a suspension fitting of an overhead ground wire of a power transmission line. Background Art
[0002] The commonly used standardized products of suspension clamps now retain the U-bolt style (usually called ship-shaped clamps), which are composed of a bracket U-bolt, a clamp hull made of forgeable cast iron, and a pressure plate. The other is a pre-twisted suspension clamp, which is used to fix the conductor on the insulator string of a straight pole tower, or to hang the lightning arrester on a straight pole tower. It can also be used to support the transposition conductor on the transposition tower and fix the jumper of the tension angle pole tower. However, due to the many types of ground wire hanging points of the transmission line tower, the long winding of the protective wire, and the many connection forms due to different tower types, terrains, ice-covered areas and spans, the tools used in the past are difficult to be universal, and it is difficult to make quick adjustments for different usage conditions. At the same time, there is a lack of storage structure for parts, which makes it very inconvenient to select smaller parts. For this reason, we propose a tool for replacing the suspension hardware of the overhead ground wire of the transmission line. Summary of the invention
