Abstract
The invention discloses a tool for shearing off fire wires and branches, which comprises a rod body which is flat at the upper part, a blade, and an elastic device, wherein the blade is rotationally arranged on the rod body; the front end of the blade is matched with the upper part of the rod body to form shears; the elastic device is arranged between the rear part of the blade and the rod body and is used for enabling the blade to return; the tail end of the blade is provided with an insulating rope for driving the blade to shear; the lower end of the rod body is provided with a joint connected with an insulating tension pole. The tool has the advantages that the structure is simple; one person can pull the insulting rope to shear off the branches or the waste fire wires; safety of an operator can be well protected; the tool is time-saving and labor-saving and has high efficiency.
Description
Technical field
The present invention relates to a kind of for cutting the instrument of live wire and branch.
Background technology
The place of or mountainous rural area dense vegetation higher in urban afforestation degree, because power circuit adopts overhead transmission line mode more, so the situation that trees and power circuit approach, touch happens occasionally, this situation is more common in region, mountain area, rural area, and the safe and stable operation of overhead transmission line is brought to hidden danger.As circuit O&M personnel, while finding that in tour trees may touch the hidden danger of circuit, for avoiding the faults such as single-phase earthing, phase fault, must prune trees, to guarantee the normal operation of circuit.
Before this, to closing on the cleaning work of live wire trees, mainly adopt in two ways:
The first, in the situation that orographic condition allows at the scene, can adopt ascend operation car, staff carries out the pruning work of branch on operating platform, is subject to the restrictions such as orographic condition, Active workings traffic environment;
The second, can not or will whole during trees felling, only have people to climb to that tree is upper to be pruned corresponding branch, waste time and energy, there is very large potential safety hazard simultaneously.
So have human hair to understand insulation saw, but stand in the lower operation of tree, branch, in stationary state not, is relatively wasted time and energy with saw saw.
In routine duties, for some low pressure discarded or that do not re-use live wire that falls, need to directly excise.Staff must step on bar or use ascend operation car can cut live wire before this, wastes time and energy, and efficiency is very low.
Summary of the invention
The object of the present invention is to provide a kind ofly for cutting the instrument of live wire and branch, the branch that can effectively solve work on hand center line roadside can touch circuit and have potential safety hazard, and discarded low fire line pressing needs excision, waste time and energy, and inefficient problem.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of for cutting the instrument of live wire and branch, comprise top be flat the body of rod, rotate be arranged on the body of rod and front end coordinate with body of rod top form scissors blade, be arranged on the elastic device that makes blade return between blade rear portion and the body of rod, the tail end of described blade is provided with the insulating cord that drives knife cut, and the lower end of the described body of rod is provided with the joint being connected with link rod.
Preferably, the head of the described body of rod is comprised of two hook-type sheets, leaves the gap of passing through for blade between two described hook-type sheets; To blade, provide good positioning action, hook-type sheet can hook and be cut object simultaneously, also to being cut object, plays fixation.
Preferably, the bottom of the described body of rod is provided with the first fixed pulley, the tail end of described blade is provided with swinging mounting, the middle part of described swinging mounting is provided with the second fixed pulley, the afterbody of described swinging mounting and the afterbody of blade are rotationally connected, one end of described insulating cord is fixed on the front end of swinging mounting, and the other end of described insulating cord is walked around the first fixed pulley and the second fixed pulley successively; Make insulating cord can better control the action that blade is cut off.
Preferably, described elastic device is extension spring, and one end of described extension spring and the top of the body of rod are fixed, and the other end of described extension spring and the tail end of blade are fixed; Extension spring low price reliability is high.
Preferably, wherein hook-type sheet lateral surface is provided with and the bolt head of surveying ammeter and being connected described in a slice; Can also detect whether wire is charged.
Compared with prior art, advantage of the present invention is: this apparatus structure is simple, and a people pulls insulating cord branch or discarded live wire can be cut off, and can well protect operating personnel's safety, and time saving and energy saving efficiency is high.
Accompanying drawing explanation
Fig. 1 is that the present invention is a kind of for cutting the structural representation of the instrument of live wire and branch;
Fig. 2 be in Fig. 1 hook-type sheet A to view.
Embodiment
Consulting Fig. 1 is that the present invention is a kind of for cutting the embodiment of the instrument of live wire and branch, a kind of for cutting the instrument of live wire and branch, comprise that top is the body of rod 1 of flat, rotation is arranged on the body of rod 1 and front end coordinates with the body of rod 1 top the blade 2 that forms scissors, be arranged on the elastic device 3 that makes blade 2 returns between blade 2 rear portions and the body of rod 1, the tail end of described blade 2 is provided with the insulating cord 4 that drives blade 2 to shear, the lower end of the described body of rod 1 is provided with the joint 6 being connected with link rod 5, the head of the described body of rod 1 is comprised of two hook-type sheets 7, as shown in Figure 2, between two described hook-type sheets 7, leave the gap 8 of passing through for blade 2, the bottom of the described body of rod 1 is provided with the first fixed pulley 9, the tail end of described blade 2 is provided with swinging mounting 10, the middle part of described swinging mounting 10 is provided with the second fixed pulley 11, the afterbody of the afterbody of described swinging mounting 10 and blade 2 is rotationally connected, one end of described insulating cord 4 is fixed on the front end of swinging mounting 10, the other end of described insulating cord 4 is walked around the first fixed pulley 9 and the second fixed pulley 11 successively, described elastic device 3 is extension spring, the top of one end of described extension spring and the body of rod 1 is fixed, the tail end of the other end of described extension spring and blade 2 is fixed, wherein described in a slice, hook-type sheet 7 lateral surfaces are provided with and the bolt head 12 of surveying ammeter and being connected.
By joint 6, the body of rod 1 and link rod 5 are connected together, then make branch or the live wire cut be positioned in the hook of hook-type sheet 7, pull insulating cord 4, insulating cord 4 will make the tail down campaign of blade 2, the head of blade 2 upwards forms scissors action with hook-type sheet 7 simultaneously, the object being positioned in hook-type sheet 7 hooks is cut off, then operator unclamps insulating cord 4, under the effect of elastic device 3, the afterbody of blade 2 moves upward, the head of blade 2 moves downward, and allows open position that the hook portions of hook-type sheet 7 is opened, and gets back to initial condition.This apparatus structure is simple, and a people can operate, and can well protect operating personnel's safety, and time saving and energy saving efficiency is high.
