Abstract

The invention relates to a climbing-free winding and tying device for transmission line tree barrier cutting. The device comprises a hoop shell (1), a hoop core (2), a ring (4), a motor (5), and a ring buckle (7). The hoop shell (1) and the hoop core (2) constitute a rope feeding mechanism moving along a fixed track. The ring is arranged at one end of the hoop core, and the ring buckle is arranged at the other end of the hoop core. The hoop core moves along a fixed track under drive of the motor to buckle the ring into the ring buckle. The ring (4) and the ring buckle (7) constitute a snap ring mechanism completing winding and tying. The winding and tying device of the invention is equipped with the rope feeding mechanism, a ring fixing device and the snap ring mechanism. When there is a need to clear a tree barrier around a transmission line, a rope can be wound around the tree and tied without climbing. The bother of rope winding by means of climbing is eliminated. The efficiency of tree barrier clearing is improved. The occurrence probability of accidents is lowered. The efficiency of charged maintenance is improved. Safe and reliable operation of the power system is ensured.

Description

technical field [0001] The invention relates to the technical field of live working tools for electric power maintenance, and in particular to a climbing-free tree-winding tether device for felling tree barriers on power transmission lines. Background technique [0002] Extremely severe weather such as heavy rain and thunderstorms have caused serious damage to power equipment. In addition to some lines being affected by lightning strikes, the more prominent damage phenomenon is that the super tall trees on both sides of the transmission line protection area are blown down by strong winds or knocked down by lightning. Trees fall down and contact wires to discharge, or even directly break the wires, causing power supply lines to trip, causing large-scale power outages, and seriously affecting people's lives and the economy and society. In summer, trees grow luxuriantly and there is a lot of rain, and the lodging resistance of trees is greatly reduced. If the super-high trees i...
