Specific embodiment
A kind of livewire work construction elastic wire clamp：
Including wire clamp base plate 4, the centre of wire clamp base plate is provided with vertically arranged threaded connection hole 5, with threaded connection hole is
Center is symmetrical to be provided with two wire fixing grooves 7, and the notch of wire fixing groove is down-set, the lower end of threaded connection hole
It is provided with the spring retainer groove 6 bigger than the diameter of threaded connection hole；Threaded connection hole is concentric design with spring retainer groove.For solid
Determine spring, spring is combined with certain restriction effect with spring retainer groove, so as to realize wire clamp pressing plate is prevented in fastener cycle
Deflection.
With wire clamp pressing plate 2, the center of wire clamp pressing plate is provided with and due bolt is passed through with the threaded connection hole of wire clamp base plate
Hole 12, is provided with two wire pressing plate grooves 11 by bolt by symmetrical centered on hole, and the notch of wire pressing plate groove is upwards
Arrange and correspond with the wire fixing groove of wire clamp base plate, the spring limit with wire clamp base plate is provided with by the upper end in hole in bolt
The corresponding spring mounting groove 10 of position groove.
With spring 3 and fastening bolt 1, spring is arranged between wire clamp base plate and wire clamp pressing plate, and the two ends of spring correspond to dress
At spring retainer groove and spring mounting groove；Fastening bolt sequentially passes through the bolt of wire clamp pressing plate from bottom to top by hole, spring
It is connected with the threaded connection hole of wire clamp base plate, wire clamp base plate and wire clamp pressing plate are in normally open all the time in spring effect.
Insulating bar draw-in groove 9 is provided with the top of wire clamp base plate, insulating bar draw-in groove is fixed for action bars, ground electricity
During the work of position, wire clamp is gone up in advance by act by insulating bar realization and main line is sent to line.The side of insulating bar draw-in groove 9
Along the block 8 for being provided with protrusion.Mainly prevent action bars clamped tool from exiting.
The bolt of wire clamp pressing plate is strip unthreaded hole by hole, and spring mounting groove is located at the centre position of strip unthreaded hole.
When the major and minor cross-sectional area great disparity of principal security is very big, pressing plate can be to any adjustment, it is ensured that bolt is reliably fastened and necessary
Wire clamp and wire section contact.Squared design is protruded for plane in wire clamp pressing plate top, is that fastening bolt spring washer is played
Act on and set.
The difficult practical challenges of upper and lower lock out operation present in powered hookup wire clip process are solved, the wire clamp has side
Just install, applicable wire scope is big, improve operating personnel's operating efficiency, improves the plurality of advantages of mounting process.Conventional 10kV joins
Netting twine road carrying out high-voltage lead of transformer band electrical bonding, in 10kV branched line and main line connection procedure, using routine
And wire clamp is hooked in powered installation process, because operating personnel need to be operated with insulating glove, cause conventional and hook
The pressing plate opening manipulation of wire clamp is difficult, and installment work efficiency is low, and operating personnel pays larger labour intensity, and mounting process is not
Good, when particularly ground potential is operated, the inconvenience for bringing more is protruded, and the utility model is directed to the problem for existing, in combination with band
The property of electric work operations, develops before one kind installs automatically wire clamp pressing plate in normally open, it is ensured that operating personnel are fast
Speed major and minor line is correctly installed in place, simplify completely original pressing plate repeatedly opening manipulation, particularly earth potential working when, work
Make efficiency improve particularly evident, mounting process is entirely capable of being guaranteed.
The cable clamp structure rationally, installs simple, current capacity by force, wire scope of application width, conductor cross-section 35-300mm2All
Can apply.According to livewire work feature, cable clamp structure meets ground potential insulating bar working system and installs wire clamp, meets using insulation
The free-hand installation of car personnel, wire clamp pressing plate novel designs open in usual, the loaded down with trivial details difficult problem of wire clamp installation operation is fundamentally solved, is installed
Technique is greatly improved, and operation intensity reduces, and operating efficiency is improved.
Using the protection invention device, mainly there is the advantage of the following aspects：
（1）New wire clamp is applied widely, and Novel wire clamps plate screwed hole and adopts oblong, realizes wire range of application
From 35mm2To 300mm2Can reliably install, in addition to installing for livewire work, also be common to power cut construction installation.
（2）Wire clamp pressing plate automatic open structure, is by wire clamp base plate and spring mounting groove set by wire clamp pressing plate, using bullet
Wire clamp base plate and pressing plate are separated by the tension force of spring automatically, and livewire work personnel manually need not carry out unlatching operation to pressing plate, greatly
Facilitate installation operation.Wire clamp base plate, wire clamp pressing plate spring spacing under, solve pressing plate and the normally closed defect of base plate, while
Pressing plate skewness in fastener cycle is also limit, finally ensure that wire clamp mounting process and quality.
（3）By spring washer, wire clamp pressing plate top design can ensure that wire clamp is realized enough for protruding planar design
Tightening force, and play locking effect.
Ground potential installation instructions：Operating personnel pedals bar to correct position, clamps wire clamp base plate top with fixing action bars convex
The insulating bar draw-in groove for going out, the wire clamp being open smoothly is gone up act and is put on main line line conductor, and another staff uses
Branched line drainage thread is fixed by another action bars and upper act is put in second half fixing groove for the wire clamp that has been open, and is finally used
Bolt fastening operating rod screws two bolts and completes whole operation.
The free-hand installation instructions of insulation car：Used as major insulation, operating personnel need to wear insulating glove and carry out hand operation insulation car.
Installation process is as follows：Operating personnel's operation insulate car to preferable station, a groove of the free-hand wire clamp by automatic open
Mouth is put on main traverse line, then branched line drainage thread is put in another wire clamp notch, you can complete with spanner fastening bolt
Become installation exercise.
