High-branch pruning pneumatic tool for charged high-voltage lines

Abstract

The invention discloses a high-branch pruning pneumatic tool for charged high-voltage lines. The high-branch pruning pneumatic tool for the charged high-voltage lines comprises a casing, and an air cylinder is arranged in the casing; a piston rod is connected with a cutting saw blade, an L-shaped protecting rod fixed on one side of the casing is arranged above the cutting saw blade; a steering block is hinged below the casing; the casing is provided with a clamping block I and a clamping block II on two sides of the steering block; the steering block is connected together with the clamping block I and the clamping block II through a tension bolt, and the connecting part of the upper part of the steering block and the casing is in the shape of a circular arc; an insulation rod is fixedly connected at the lower end of the steering block. According to the invention, the hand-held operation part of the high-branch pruning pneumatic tool for the charged high-voltage lines is formed by combining the hollow insulation rod and an insulation pull rope, so that the high-branch pruning pneumatic tool for the charged high-voltage lines has the insulation function, and the protecting rod is arranged to provide a certain safe working range for the cutting saw blade; the high-branch pruning pneumatic tool has a cutter steering mechanism, thereby being convenient for pruning tree branches in any direction to improve the labor efficiency.

Description

technical field [0001] The invention relates to the field of electric power construction maintenance tools, in particular to a pneumatic tool for high-branch pruning of live high-voltage lines. Background technique [0002] In the channel management of overhead transmission lines, the contradiction between wires and trees has always been a prominent and serious problem. On the one hand, with the rapid development of urban construction, greening construction such as new roads and parks has gradually increased, and the government's greening department has implemented " The Regulations on the Protection of Electric Power Facilities is not well understood, and large-scale tree planting often occurs under transmission lines, resulting in the distance between some line conductors and trees not meeting the specified requirements; on the other hand, overhead lines span a wide range, and there are many and mixed trees in the passage protection area , coupled with the enhanced awarene...

AI Technical Summary

Problems solved by technology

The commonly used high-branch shears are purchased in the market, and the operating unit found the following defects in the process of pruning trees with the existing ordinary high-branch shears in the market: 1. Insulation problems, traditional high-branch shears are not suitable for trees near high-voltage lines Therefore, the trees that do not meet the safety distance in the high-voltage line protection area cannot be trimmed during use, which limits the scope of use; 2. The direction of the blade head of the traditional high-branch shears is fixed, and the horizontal branch pruning effect Good, but the pruning of branches in other directions is difficult, time-consuming and easy to break the cutter head; 3. The traditional high-branch shears use the pulley block labor-saving device, which reduces the labor intensity of the operator to a certain extent, but in the process of pruning , it is prone to the phenomenon that the cutter head is stuck, and the operation cannot be continued, which virtually increases the labor time and labor intensity

Due to the above defects, the high-branch shears are time-consuming and labor-intensive in use, which affects work efficiency.
