The method of charged for replacement drainage thread parallel groove clamp
Technical field
The present invention relates to a kind of method of charged for replacement drainage thread parallel groove clamp.
Background technology
Live line working belongs to special work post, is high intelligence, high professional qualification, high investment, high risk work, is the operation that guarantees that power network safety operation does not have a power failure.Along with developing rapidly of electrical network, the increase of circuit is more and more, and charged elimination line defct task is heavy day by day.In order to guarantee the transmission line operational reliability, live line working is absolutely necessary; Because many circuit long operational times, ageing equipment, load weigh; Line conductor connecting portion appearance temperature raises; The phenomenon that lead is blown (particularly meeting period in kurtosis summer); This phenomenon especially occurs in the drainage thread parallel groove clamp place of junction, to the problems referred to above, eliminates the shaft tower drainage thread at present and the ditch line adopts usually: fastening when serious (need change whole drainage thread) and charged fastening two kinds of forms have a power failure: though one, have a power failure this kind of method ability good treatment defective fastening; Need planned power failure but have a power failure, promptly compel to stop with examining with unplanned stoppage in transit like need.Influence the transmission line power supply reliability same trade to mark.Add that handling similar defective circuit need have a power failure about four hours, the circuit availability coefficient obviously descends, the also corresponding increase of recondition expense; Two, adopt charged fastening method, though the circuit reliability operation has reached index, line load rising parallel groove clamp temperature raises equally.At any time can drainage thread be blown (causing one type of fault of circuit), this type of defective obviously can not well solve, and labour intensity is big, and is dangerous high.
Summary of the invention
The object of the present invention is to provide a kind of method of charged for replacement drainage thread parallel groove clamp, it has simple to operate, the advantage of safe ready.
The present invention realizes 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) inspection bolt burn situation; If the bolt burn causes bolt torsion to descend, then use disassembling bolts and fastened tools to remove the bolt of fastening parallel groove clamp and pressing plate, fastening parallel groove clamp separates with pressing plate automatically; 2) use the fixedly position of parallel groove clamp of parallel groove clamp erecting tools, be placed into pressing plate on the parallel groove clamp with the pressing plate erecting tools then, at last with the bolt of disassembling bolts and fastening parallel groove clamp of fastened tools and pressing plate; Described disassembling bolts and fastened tools comprise 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, and the sleeve internal fixation is connected with magnet; Described parallel groove clamp erecting tools comprises pallet device, holder bar, metallic channel and insulating bar, and the pallet device is connected the lower end of insulating bar through helicitic texture, and the side of pallet device is provided with the holder bar, and the middle part of pallet device is provided with metallic channel; Described pressing plate erecting tools comprises insulating bar and grapple, and two grapple symmetries are fixedly connected on the lower end of insulating bar.
Technique effect of the present invention is: the method for charged for replacement drainage thread parallel groove clamp of the present invention makes operating personnel reduce to 6 people by 12 former people and can accomplish; Labour intensity obviously reduces; Easy to operate, and, make charged job security improve because staff and electric field keep a safe distance.

Embodiment
The present invention realizes 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) inspection bolt burn situation; If the bolt burn causes bolt torsion to descend, then use disassembling bolts and fastened tools to remove the bolt of fastening parallel groove clamp and pressing plate, fastening parallel groove clamp separates with pressing plate automatically; 2) use the fixedly position of parallel groove clamp of parallel groove clamp erecting tools, be placed into pressing plate on the parallel groove clamp with the pressing plate erecting tools then, at last with the bolt of disassembling bolts and fastening parallel groove clamp of fastened tools and pressing plate;
Described disassembling bolts and fastened tools structure such as accompanying drawing 1, it comprises 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, and sleeve 4 internal fixation are connected with magnet 3;
Described parallel groove clamp erecting tools structure such as accompanying drawing 2; It comprises pallet device 5, holder bar 6, metallic channel 7 and insulating bar 2; Pallet device 5 is connected the lower end of insulating bar 2 through helicitic texture, and the side of pallet device 5 is provided with holder bar 6, and the middle part of pallet device 5 is provided with metallic channel 7;
Described pressing plate erecting tools structure such as accompanying drawing 3, it comprises that insulating bar 2 and 8, two grapple 8 symmetries of grapple are fixedly connected on the lower end of insulating bar 2.
In implementation process, the operating process of changing the drainage thread parallel groove clamp is:
1, at first the operator uses disassembling bolts and fastened tools; The user catches an end of insulating bar 2; Entangle the nut on the drainage thread parallel groove clamp with sleeve 4, rotate rotary handle 1, under the effect of magnet 3 and rotary torsion; Dismounting is the screw threads for fastening structure of drainage thread parallel groove clamp down, and this moment, parallel groove clamp and pressing plate came off under the effect of gravity naturally;
2, use the parallel groove clamp erecting tools then; The user catches insulating bar 2; Hold parallel groove clamp with pallet device 5, the holder bar 6 on the pallet device 5 blocks parallel groove clamp with metallic channel 7, moves insulating bar 2 and is placed into the parallel groove clamp on the pallet device 5 position that needs installation; Another operating personnel use the pressing plate erecting tools, use grapple 8 to catch a pressing plate earlier, utilize insulating bar 2 to move to pressing plate on the parallel groove clamp then;
3, use disassembling bolts and fastened tools at last, adsorb nuts and bolt with the magnet 3 that is positioned at sleeve 4, and be placed on the appropriate location of parallel groove clamp, rotate rotary handle 1 then, accomplish the fastening of helicitic texture.
