Description
Technical field
The utility model relates to power circuit maintenance tool fields, and in particular to a kind of orientation auxiliary protection for chopping at a tree
Tool.
Background technique
A large amount of quick woodss are nearby often planted in the line corridor lower section of 10kV medium-voltage line, in order to guarantee conducting wire and tree
Safe clearance distance between wood, need often fall trees.Due to not controlling the direction of tree falls down, trees are fallen
It will be easy to cause short-circuit tripping on the line when lower, the safe and stable operation of route be influenced very big.
Existing processing mode has following three kinds:
One: one people of mode falls trees, and the opposite direction of another person towards 10kV medium-voltage line pushes trees, makes trees
Bottom end break apart by chopping after can directioning falling, prevent trees pound cause on conducting wire 10kV medium-voltage line short-circuit between conductors trip.
The shortcomings that mode one is: the direction that trees are toppled over is difficult to control；The knife that chops at a tree is easy to accidentally injure the personnel of treedozer wood；Hold
Easily cause electric shock accidents.
Mode two: using the fixed wood to be chopped at a tree of rope, two staff make trees by two rope ends of pulling rope
After breaking apart by chopping can directioning falling, prevent conducting wire from discharging with the trees toppled over since clearance is insufficient.
The shortcomings that mode two is: it is more that personnel expend physical strength；After trees fall down to the ground, if pushing down rope, it will increase additional
Work load.
Mode three: application No. is CN201520801635.1 to describe a kind of orientation auxiliary protection tool for chopping at a tree
The shortcomings that mode three, is: being chopped at a tree using the tool, due to needing to pull to trees the direction of operator, is easy
Because operator hides not in time, trees occur and injure operator's accident by a crashing object；The insulating properties of the tool is unable to effective protection human body,
The operation handle of the tool does not have good insulation performance.
Utility model content
The utility model is a kind of orientation auxiliary protection tool for chopping at a tree, including undertake part and strut, carrier
