The method of charged for replacement drainage thread parallel groove clamp
Technical field
A kind of method that the present invention relates to charged for replacement drainage thread parallel groove clamp.
Background technology
Livewire work belongs to special work post, is high intelligence, high professional qualification, high investment, high risk work, is to ensure that the operation that power network safety operation does not has a power failure.Along with developing rapidly of electrical network, the increase of circuit gets more and more, and charged elimination line defct task is the heaviest.In order to ensure transmission line of electricity operational reliability, livewire work is requisite;Due to many circuit long operational times, ageing equipment, load weight, line conductor connecting portion occurs that temperature raises, phenomenon that wire is blown (particularly summer peak meeting period), this phenomenon occurs especially at the drainage thread parallel groove clamp of junction, for the problems referred to above, eliminate shaft tower drainage thread at present and ditch line generally uses: have a power failure fastening (need to change whole drainage thread time serious) and two kinds of forms of Electrified fastening: one, although having a power failure, the method for fastening can well process this kind of defect, but have a power failure and need planned power failure, as need to be promptly compeled to stop examine with unplanned outage.Affect transmission line of electricity power supply reliability fellow peers' evaluation.Need to have a power failure about four hours plus processing similar defect circuit, circuit availability coefficient is decreased obviously, and the cost of overhaul increases the most accordingly;Two, the method using Electrified fastening, although circuit reliability is run and reached index, but line load raises parallel groove clamp temperature and raises equally.Drainage thread can blow (causing circuit one class fault) at any time, and this type of defect not can solve, and labor intensity is big, dangerous high.
Summary of the invention
A kind of method that object of the present invention is to provide charged for replacement drainage thread parallel groove clamp, it has simple to operate, the advantage of safe ready.
The present invention is achieved like this, a kind of method of charged for replacement drainage thread parallel groove clamp, it is characterized in that said method comprising the steps of: 1) check bolt burn situation, if bolt burn causes bolt torsion to decline, then using disassembling bolts and fastening instrument to remove fastening parallel groove clamp and the bolt of pressing plate, fastening parallel groove clamp and pressing plate are automatically separated;2) use parallel groove clamp installation tool to fix the position of parallel groove clamp, then by pressing plate installation tool, pressing plate is placed on parallel groove clamp, finally with disassembling bolts and fastening instrument fastening parallel groove clamp and the bolt of pressing plate;Described disassembling bolts and fastening instrument include rotary handle, insulating bar, Magnet and sleeve, and the upper end of insulating bar is connected with rotary handle, and the lower end of insulating bar is fixedly connected with sleeve, are fixed with Magnet in sleeve;Described parallel groove clamp installation tool includes pallet device, torr bar, metallic channel and insulating bar, and pallet device is connected to the lower end of insulating bar by helicitic texture, and the side of pallet device is provided with torr bar, and the middle part of pallet device is provided with metallic channel;Described pressing plate installation tool includes that insulating bar and grapple, two grapple symmetries are fixedly connected on the lower end of insulating bar.
The solution have the advantages that: the method for charged for replacement drainage thread parallel groove clamp of the present invention makes operator be reduced to 6 people by 12 former people can to complete, labor intensity substantially reduces, easy to operate, and owing to staff keeps safe distance with electric field so that live line work safety improves.

Detailed description of the invention
The present invention is achieved like this, a kind of method of charged for replacement drainage thread parallel groove clamp, it is characterized in that said method comprising the steps of: 1) check bolt burn situation, if bolt burn causes bolt torsion to decline, then using disassembling bolts and fastening instrument to remove fastening parallel groove clamp and the bolt of pressing plate, fastening parallel groove clamp and pressing plate are automatically separated;2) use parallel groove clamp installation tool to fix the position of parallel groove clamp, then by pressing plate installation tool, pressing plate is placed on parallel groove clamp, finally with disassembling bolts and fastening instrument fastening parallel groove clamp and the bolt of pressing plate;
Described disassembling bolts and fastening tool construction such as accompanying drawing 1, it includes rotary handle 1, insulating bar 2, Magnet 3 and sleeve 4, and the upper end of insulating bar 2 is connected with rotary handle 1, and the lower end of insulating bar 2 is fixedly connected with sleeve 4, is fixed with Magnet 3 in sleeve 4;
Described parallel groove clamp installation tool structure such as accompanying drawing 2, it includes pallet device 5, torr bar 6, metallic channel 7 and insulating bar 2, and pallet device 5 is connected to the lower end of insulating bar 2 by helicitic texture, and the side of pallet device 5 is provided with and holds in the palm bar 6, and the middle part of pallet device 5 is provided with metallic channel 7;
Described pressing plate installation tool structure such as accompanying drawing 3, it includes that insulating bar 2 and grapple 8, two grapple 8 symmetries are fixedly connected on the lower end of insulating bar 2.
In implementation process, the operating process changing drainage thread parallel groove clamp is:
1, first operator uses disassembling bolts and fastening instrument, user catches one end of insulating bar 2, the nut on drainage thread parallel groove clamp is entangled with sleeve 4, rotate rotary handle 1, under the effect of Magnet 3 and rotary torsion, the screw threads for fastening structure of the lower drainage thread parallel groove clamp of dismounting, now parallel groove clamp and pressing plate come off the most naturally;
2, then using parallel groove clamp installation tool, user is caught insulating bar 2, is held parallel groove clamp with pallet device 5, and torr bar 6 and metallic channel 7 on pallet device 5 block parallel groove clamp, and the parallel groove clamp on mobile 2 pallet devices 5 of insulating bar is placed into and needs position to be mounted;Another operator use pressing plate installation tool, first use grapple 8 to catch a pressing plate, then utilize 2 pressing plates of insulating bar to move on parallel groove clamp;
3, finally use disassembling bolts and fastening instrument, adsorb nuts and bolt with the Magnet 3 being positioned at sleeve 4, and be placed on the appropriate location of parallel groove clamp, then rotate rotary handle 1, complete the fastening of helicitic texture.
