Abstract

The invention discloses a special rope throwing device for cleaning a tree barrier of a transmission line. The special rope throwing device comprises a pulley, a supporting shaft, a supporting rack, a connecting rack and a supporting rod, wherein the pulley is rotatably mounted on the supporting shaft; two ends of the supporting shaft are respectively fixed on the supporting rack; the connecting rack is provided with a positioning part, a first connecting part and a second connecting part; the positioning part is in lap joint on a branch; the first connecting part and the second connecting part are arranged at two ends of the positioning part; the supporting rack is connected with the first connecting part; and the supporting rod is connected with the second connecting part. The special rope throwing device is simple in structure and easy to manufacture, can be used by supporting the supporting rod on the ground, is convenient to operate, accurate in rope throwing position and high in success rate, and has the advantage that a tool is automatically separated from a rope. Rope throwing operation for cleaning of the tree barrier of the transmission line is realized, safety risks of falling of operators from high positions or accidental electric shock of the operators and the like are avoided effectively, and the working efficiency is improved effectively.

Description

technical field [0001] The invention relates to transmission line operation and maintenance equipment, in particular to a special rope throwing device for clearing tree barriers of transmission lines. Background technique [0002] With the rapid development of my country's economy and the deepening reform of the power system, the degree and scale of power grid construction continue to expand, the distribution points of overhead transmission lines are multi-faceted and intricate, and factors such as the external environment affect the safe and stable operation of transmission lines. tripping has become one of the important safety hazards. [0003] In the operation and maintenance of transmission lines, in order to effectively prevent the occurrence of transmission line tripping accidents due to line tree contradictions, operation and maintenance personnel need to regularly cut down and eliminate tree barriers in the transmission line passages and protection areas under their j...
