Description

A kind of universal adapter for livewire work
Technical field
This utility model belongs to power industry, the specific purpose tool structure skill of a kind of charged for replacement 220kV straight line bunch of insulator Art field.
Background technology
At present, Work tool used by charged for replacement 220kV linear insulator chain, is all complete with wire by preferable cross arm of tower Entirely manufacture and design at an angle of 90, but the angle of the cross-arm in actual motion equipment and wire is not the right angle of standard, all has one Fixed differential seat angle.In operation process, Work tool stress is undesirable, is easily damaged, installation exercise instrument difficulty, increases operating personnel Labor intensity, even can not change by charged for replacement, can only be forced to line outage and overhaul, add operating risk, increase Equipment power off time, seriously reduces the availability coefficient of equipment, reduces the reliability of power supply.
During charged for replacement 220kV linear insulator chain, use isoelectric level and earth potential combined techniques.Instrument has: lifting rope, Rope ladder frame, insulated flexible ladder, insulation pulling plate, insulation coaster, line lifter, screw mandrel etc..Due to the variation of cross arm of tower, the peace caused Dress power tool difficulty, increases operating personnel's labor intensity, even can not charged for replacement.
Summary of the invention
The purpose of this utility model precisely in order to overcome defect that above-mentioned prior art exists and design rotatable, can Solve cross-arm and wire angle problem, can be suitably used for the replacing of all linear insulator chains, operating risk value low, safe and reliable and The specific purpose tool of time saving and energy saving overhead transmission line replacing linear insulator string under electrification.The purpose of this utility model is by such as Lower technical scheme realizes:
A kind of universal adapter for livewire work, this utility model is characterised by, including a upper connective plate and Individual lower linking plate;By the nut segment threaded engagement being connected in the bolt section of upper connective plate and lower linking plate between upper connective plate with lower linking plate Connect, bolt section offers little screw M, nut segment offers little screw N, bolt section and nut segment spiral and arrives one Location is put and is made little screw M, little screw N form coincidence;Screw in little screw with bolt, loosen during preventing from using;Described spiral shell Bolt section sets with one section of endoporus;
It is provided with when jackshaft connects on lower linking plate is axial and passes nut segment and extend in described endoporus;
Upper connective plate laterally offers first line of a couplet hole be connected with livewire work specific purpose tool insulation pulling plate, horizontal on lower linking plate It is connected with livewire work specific purpose tool line lifter to offering second line of a couplet hole;
Between described nut segment and lower linking plate, bearing and lower linking plate by being fixed on jackshaft connect and compose one Overall;Enable bearing to make 360 ° of rotations around axial line, bear corresponding pulling force simultaneously.
The beneficial effects of the utility model are: this utility model can solve charged for replacement 220kV linear insulator chain in the past Work tool stress is undesirable, is easily damaged, installation exercise instrument difficulty, and operating personnel's labor intensity is big, even can not charged more The problem changed, substantially increases work efficiency, make operating risk value reduce, safe and reliable and time saving and energy saving, make replacing power transmission line The upkeep operation of road linear string is more standardized, standardization.

Detailed description of the invention
Seeing Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of universal adapter for livewire work, this utility model is characterised by, Including a upper connective plate 1 and a lower linking plate 4;By bolt section 2 and the lower linking plate of upper connective plate between upper connective plate and lower linking plate Nut segment 3 threaded engagement of upper connection connects, and offers little screw M7, offer little screw in nut segment 3 in bolt section 2 N7, bolt section 2 and nut segment 3 spiral arrive certain position makes little screw M7, little screw N7 form coincidence;Screw in little with bolt 8 In screw 7, loosen during preventing from using;Described bolt section 2 sets with one section of endoporus 10;
It is provided with when jackshaft 11 connects on lower linking plate 4 is axial and passes nut segment 3 and extend in described endoporus 10;
Upper connective plate 1 laterally offers first line of a couplet hole 9 be connected with livewire work specific purpose tool insulation pulling plate, at lower linking plate 4 On laterally offer second line of a couplet hole 6 and be connected with livewire work specific purpose tool line lifter;
Between described nut segment 3 and lower linking plate 4, the bearing 5 by being fixed on jackshaft 11 is connected structure with lower linking plate 4 Become an entirety;Make bearing 5 can make 360 ° of rotations around axial line, bear corresponding pulling force simultaneously.
This utility model uses metal material to make, and can bear the working pulling force of daily 80KN, and maximum can bear 200KN Pulling force.
In livewire work, change transmission line of electricity 220kV linear string bunch of insulator time, can only use isoelectric level with Earth potential combined techniques.Instrument has: lifting rope, rope ladder frame, insulated flexible ladder, insulation pulling plate, insulation coaster, line lifter, screw mandrel etc..Due to These Work tools are all manufactured and designed with wire the most at an angle of 90 by preferable cross arm of tower, but in actual motion equipment The angle of cross-arm and wire is not the right angle of standard, all has certain differential seat angle.This utility model comes with an adapter Reaching to change the effect of this angle, prevent Work tool stress in Renewal process undesirable, be easily damaged, installation exercise instrument is stranded The problems such as difficulty.This utility model installs an adapter on instrument additional, with insulation pulling plate with the use of, by isoelectric level, electrician pacifies Dress is more time saving and energy saving when operating.After this utility model specific purpose tool uses, the labor intensity of equipotential live line work personnel can be reduced, It is greatly shortened the activity duration, thus realizes the risk during reduction operating personnel's Equipotential live working.
2. tool materials, structure technology requirement
Material is LuCr-60, φ 40 aluminum alloy materials, and smooth surface is smooth and carries out preservative treatment, and workload is 80kN, bearable load 200kN safety coefficient is 2.5 times.
