Problems solved by technology

[0002] As we all know, with the continuous development of social economy, the public has higher and higher requirements for reliable power supply. Due to the advantages of small footprint, low investment, fast construction speed, beautiful and practical, etc., steel pipe poles have been used in the construction of urban power grids in recent years. A large number of applications, however, with the continuous increase of power lines, some equipment is gradually aging, and the daily maintenance and repair tasks of power transmission lines are becoming more and more heavy. Due to the smooth surface of steel pipe rods and steel pipes in line design, the operating space is narrow, especially when the crossarm is placed on the wire The pole is easy to tilt, resulting in different counterweights on the left and right sides, which makes the work of replacing insulator strings and cross arms more and more difficult, and brings difficulties to the task of live maintenance of equipment. The hoist lifts the wire, and then manually replaces the insulator string and the cross arm. This method requires a large amount of engineering, increases manpower and material resources, and reduces work efficiency. It is impossible to replace the cross arm and insulator string at the same time.
