Description

Control Line Clearance Tree Bamboo Inverted Pole

technical field

The utility model relates to a construction tool for a power transmission line, in particular to a tree and bamboo inverted support rod for clearing obstacles of a control line. the

Background technique

Since most of the transmission lines are erected in the wilderness and mountainous areas, and the lines pass through special areas such as forest farms, moso bamboo growth areas, nature reserves, and economic forest areas, a large number of trees and bamboos grow in the line passages every year. In order to ensure the safe operation of the transmission lines , according to the "DL/T 741-2010 Operation Regulations for Overhead Transmission Lines", the trees and bamboos that cannot meet the operation requirements must be felled. Because the work is carried out near the high-voltage live line, safety measures must be taken to control the fall of the tree and bamboo before the operation. The traditional operation method is to climb up to the top of the tree and bamboo and tie one end of the rope, and then several workers hold it The other end of the pull rope controls the falling of the trees and bamboos to prevent the trees and bamboos from falling to the side of the line and crushing the lines. Another operator can use a chainsaw to saw the roots of the trees and bamboos to complete the task of clearing obstacles, which not only wastes Time, work efficiency is low, and the labor intensity of operator is also big, and safety is poor. the

Contents of the invention

The purpose of the utility model is to provide a control circuit clearing tree and bamboo inverted support bar which saves working time, has high working efficiency, reduces the labor intensity of operators, is simple to operate, safe and reliable, and is convenient to carry. the

The purpose of this utility model is achieved in that:

A tree and bamboo inverted stay for controlling line clearing obstacles, including a long tubular stay body, characterized in that: a U-shaped fork with an opening facing forward is fixed on the top of the stay body, and a front-facing fork in the middle of the U-shaped fork The bottom is fixed with a sharp anti-skid thorn at the front end, and a backward barb is fixed at the bottom of the U-shaped fork facing backward.

 The rear bottom in the middle of the U-shaped fork is a columnar body, which is inserted into the tube hole at the top of the strut body, and the U-shaped fork is fixed on the top of the strut body with screws.

The elongated tube-shaped strut body is a telescopic rod, which is composed of 2-4 sections of support rods, and the adjacent two-section support rods are fixed or loosened by rotatable joint screws.

A non-slip plastic handle is sheathed on the bottom end of the strut body.

The utility model consists of a strut body and a U-shaped fork. A U-shaped fork with an opening facing forward is fixed on the top of the strut body. A sharp anti-slip thorn is fixed at the bottom of the U-shaped fork facing forward. The rear-facing bottom is fixed with backward barbs, and the strut body is a telescopic rod consisting of 2-4 sections of struts. When clearing tree barriers on the line, ① if the height of the trees and bamboos does not exceed 12 meters, and the main pole is relatively strong, it is not necessary to bind the rope to control the inversion, but the pole body composed of three poles is 30o-45o The specific operation method is as follows: the operator first adjusts the length of the strut body, holds the strut body in hand, aligns the U-shaped fork with the center of gravity of the trunk and pushes it hard, so that the pointed end of the non-slip thorn will not penetrate into the trunk. Slide, and also pierce the pointed end of the anti-skid thorn of the other pole body into the tree trunk, and then forcefully push it in the backward direction at an angle of 30o-45o. ②If the growth height of the tree and bamboo exceeds 12 meters and the main pole is thick, use the main body of the pole to control the tying of the backward rope, instead of the operator climbing the tree and bamboo, so as to eliminate the risk of workers falling from high altitude and shorten the safety measures The effect of time, the specific operation method is: first hang the control rope in the 2U-shaped fork, use the pole body to lift to the height of the center of gravity of the tree bamboo and pass through the branches, and then use the 3 barbs of the other pole body to hook The hanging loop of the control rope is pulled down to the ground, and the operator puts the control rope into the hanging loop of the control rope to tighten it. When another operator uses a chainsaw to saw the roots of the bamboo, the bamboo to be cut is pulled Move to a safe falling area and complete the felling. ③ For tree species with small diameter and fast growth, such as moso bamboo, poplar, fir, etc., you can directly insert the non-slip thorn in the middle of the U-shaped fork into the trunk for pushing, which can save a lot of preparation time for safety measures and improve work efficiency.

The utility model saves the process of operators climbing trees and binding them, avoids the risk of operators falling from high altitude, greatly shortens the preparation time for safety measures, improves the efficiency of clearing obstacles in the overhead transmission line channel, and has the advantages of saving working time and high working efficiency , Reduce the labor intensity of operators, simple operation, safe and reliable, and easy to carry. the
