Abstract

Atree cutting-down tool for cutting down trees under leads comprises a hook, a hinge pin, an insulating control rod and an insulating rope, wherein a small hole is formed in a position, which is close to the tail, of the hook, and the hook is hinged to the insulating control rod through the hinge pin; a through hole for tying the insulating rope is formed in the tail of the hook, and one end of the insulating rope is tied on the through hole. The tool has the advantages as follows: the tool is simple in principle structure and good in practicability and has a control function; a worker can use the tool on a near-electricity side through the insulating tree cutting-down hook, and the application range is wide; during cutting down of trees, the worker controls the special tree cutting-down hook on the ground to fix the trees to control falling directions of the trees, so that falling of persons due to the fact that corresponding persons climb the trees to tie ropes is avoided. When the trees are fixed by the tree cutting-down hook, the working state can be adjusted under the control action of the insulating rope, the working efficiency is improved, and the lead power outage handling time is shortened greatly; and the tool is simple to operate, firm, durable and good in stability.

Description

The instrument of cutting down trees of a kind of trees of cutting down wire below
Technical field
The utility model relates to the field of tool of cutting down trees, particularly the instrument of cutting down trees of a kind of trees of cutting down wire below.
Background technology
Along with the quickening of power grid construction process, transmission line of electricity is actively implemented " not having a power failure " power supply strategy, and not having a power failure to power in future to obtain power supply trend.What specialty was cut down trees cut down trees hooks the strategy that do not have a power failure that can ensure to greatest extent circuit, there is good practicality, can in the situation that not having a power failure, cut down the trees below circuit, and cost is not too high again, can better improve power supply reliability and safety, save the operation of circuit science safety.
Social economy's fast development, power grid construction has also reached unprecedented speed, due to the centrality of transmission line of electricity, fulminant construction, cause the not felling in time of trees in line protection district, wood to be cut down trees significantly increases, greatly increase the probability of circuit to trees electric discharge, the safe and stable operation of circuit has been produced to serious threat.Accomplish to report in time the trees hidden danger in line protection district, accomplishing falls trees in time becomes an important job of overhauling company's transmission of electricity fortune inspection, but cut down higher trees in circuit guard plot time, usually run into and can not control trees toppling direction, the trees that can topple over touch charged wire, cause personnel's injures and deaths and the damage of equipment, secondly when maintainer climbs the tree tied rope so that when the direction that control trees are toppled over, easily generation personnel fall the situation generation of lower trees, and personnel casualty accidents occurs.
Utility model content
The purpose of this utility model is that spy provides the instrument of cutting down trees of a kind of trees of cutting down wire below for the ease of felling wire below trees.
The utility model provides the instrument of cutting down trees of a kind of trees of cutting down wire below, it is characterized in that: the instrument of cutting down trees of the trees of described felling wire below, comprises and hook body 1, bearing pin 2, insulation control lever 3, insulating cord 4;
Wherein: hook the close tail position of body 1 with aperture, hinged with insulation control lever 3 by bearing pin 2; The tail position band that hooks body 1 is useful on the through hole 101 of bolt insulating cord 4, and one end bolt of insulating cord 4 is on this through hole 101.
On the inner ring of described hook body 1 with laciniation 102.
On described hook body 1, through hole 101 is greater than 50 millimeters with aperture position spacing.
The structure of described hook body 1 is for being greater than four/three-arc structure.
Described insulation control lever 3 is Split connection structure.
Insulating cord 4 is free adjustment length in stroke range, for controlling the duty of cutting down trees and hooking.
Described hook body 1 is that an alloy hooks body member.
Advantage of the present utility model:
The instrument of cutting down trees of the trees of felling wire described in the utility model below, theory structure is simple, with good practicality and control function, staff cuts down trees to hook through use insulation and can ensure to use in nearly electric side, the scope of application is wide, in the time falling trees, control the special hook of cutting down trees by personnel on ground and fix trees and accomplish to control trees toppling direction, the personnel that tied rope causes thereby the corresponding personnel that avoid climb the tree fall.Cut down trees and hook while fixing trees and can adjust duty by the control action of insulating cord, can effectively solve the each trees defect below felling wire time, due to trees, conductor spacing is crossed the problem of felling toppling direction inconvenience control of near and trees etc., favourable increase operating efficiency, greatly limit reduces the time that wire power failure is processed, simple to operate, sturdy and durable, good stability.
