Embodiment
Below in conjunction with accompanying drawing, as example of making, technical scheme is further illustrated.
Reference picture 1,2,3,4,5, constitutes and changes double in three parts of the double string horizontal insulator instruments of 500KV straight lines simply connected
Join overturning plate clamp 1 by turnover panel 14 and card body 9, rotated and connected and composed by rotating shaft 10；Pass through mutual ratcheting shape between turnover panel 14 and card body 9
The axis hole that the junction surface of formula is issued, penetrates rotating shaft 10 in axis hole, and axle lower end is fixed with pad and swivel nut, and the upper end of rotating shaft 10 has one
The individual spindle nose more than axis hole makees axle shelves.It is consistent with turnover panel shape with the anastomotic part of turnover panel 14 on card body 9；After the two is combined,
Between form a clip slot, the width of clip slot is slightly less than the duplex plate thickness of the existing insulator chain used, in order in use,
Duplex board 21 is clamped in this clip slot.In the central spot expense hole 12 of card body 9 and the assembly of turnover panel 14, this pin-and-hole 12 runs through
Turnover panel 14；It is fixed in 3 Screws by lid 13 is padded at pin-and-hole 12, then hexagonal (hexagon)nut 11 is fixed on pad lid 13.In use,
The bolt head of the one end of duplex board 21 is stuck in hexagonal (hexagon)nut 11 through the hexagonal (hexagon)nut 11 at pin-and-hole 12；Screw the one end of turnover panel 14
Hanging plate 2 at attachment screw, make card body 9 and the formation clip slot of turnover panel 14 one end for stretching into duplex board 21 in its groove firm
Clamp, you can change the insulator chain 20 being located in duplex board 21 on this clamped one end.Positioned at the two ends perforate of card body 9, respectively
With the affixed hanging plate 2 of screw, hanging plate upper/lower terminal has connecting hole, and upper hole is connected with card body 9, and lower opening is used for adjustable insulation
Pull-rod 3 or adjustable insulation pulling plate 23 are connected.It is the connecting hole 24 for selecting diverse location during with adjustable insulation board 23, changes its length
The mode of degree reaches adjustable purpose, when selecting adjustable insulation pull-rod 3, and length is realized using the adjustable insulation pull-rod combination of different length
The requirement of degree.
It is main to constitute the top of four line hooks 5 in three parts of the double string horizontal insulator instruments of replacing 500KV straight lines simply connected
Body 16, makes two ends and is slightly below middle part, middle part is convex, and the size shape generous compared with two ends, two ends make have the mouth of hook upward
Thread hook is as rising to the bait 8；Two rise to the bait 8 hook underneath side make a downward circular arc under convex portion, in lower convex portion perforate,
There is the shank of thread hook by each affixed lower end of screw 17, as lower hook 7, the length of shank should adapt to current electric power transmission tower
The requirement of discrepancy in elevation size between upper twice of 22 liang of upper four wires.Central spot perforate in the top and bottom of main body 16, can allow worm gear snail
The screw mandrel 4 of bar is stretched out, then centered on the lower mouth in this hole, four screws are opened around, and worm and gear 6 is installed with screw 18；Snail
The operation spanner 19 of worm and gear 6 uses rechargeable electric wrench, is easy to when changing insulator, laborsaving fast during operation worm and gear
Speed.A connector 15 for having connecting hole is fixedly mounted with the upper end of worm and gear 4, is easy to draw with adjustable insulation pull-rod or adjustable insulation
Plate is connected.
The adjustable insulation pull-rod changed in three parts of the double string horizontal insulator instruments of 500KV straight lines simply connected is constituted, is this
The part that example is selected, is linked together by two sections by joint screw, then its upper end and the card body 9 of duplex overturning plate clamp 1
On hanging plate 2 connect, the mode connects for screw of connector 15 of the screw mandrel 4 of lower end and worm and gear is firm.
It is connected with the adjustable insulation pull-rod 3 of two four line hooks 5 and two sets with duplex overturning plate clamp 1 and makes replacing 500KV straight lines
The double string horizontal insulator instruments of simply connected.
Reference picture 4, during using changing 500KV straight lines simply connected pair string horizontal insulator tool changing insulator chain, by following
Mode is operated：
The bolt being connected positioned at the outer end of turnover panel 14 with hanging plate 2 is taken out, just can be turnover panel 14 along the rotating opening of axle 10, afterwards
On one end of duplex board 21 in insertion, the hexagonal spiral shell that hex nut 11 is fastened in the one end of duplex board 21, turnover panel 14 is closed, is penetrated
The connecting bolt of hanging plate 2 and card body 9 is simultaneously screwed, and duplex overturning plate clamp 1 just clamps duplex board 21.Again by underlying four transmissions of electricity
Wire 22 is linked into the two of corresponding four lines hook 5 and risen to the bait in 8 and twice hooks 7, and the gravity of wire 22 just all moves and changing 500KV straight lines
On the double string horizontal insulator instruments of simply connected, you can change the insulator chain that this one end duplex overturning plate clamp 1 Nei is sandwiched in duplex board
20.After replacing terminates, then the duplex board other end is clamped in the same way, change the insulator chain on the other end.What is illustrated is
Duplex board 21 on transmission line of electricity, the hanging hole at its upper convex portion center is mounted with electric power pylon, and respectively there are a string of insulation at two ends
Son 20 is connected with four wires 22 of lower section by combining yoke plate.
Specified operational procedure：
When the 1st, changing insulator chain, No. 1 electrician is arranged on to be replaced after duplex overturning plate clamp turnover panel traveling nut is opened
In the duplex board 21 of insulator chain, and the nut at center keyhole 12 is set closely to be connected with duplex board load bolt；
2nd, No. 1 electrician installs adjustable insulation pull-rod 3 at the connecting plate of duplex overturning plate clamp both sides；After screwing, adjustable insulation is drawn
Rod 3 is fixed, meanwhile, turnover panel 14 also clamps duplex board 21；
3rd, No. 1 electrician and equipotential electrician coordinate installs four line hooks 5 at wire, by equipotential electrician by turbine and worm silk
Bar 4 is connected with adjustable insulation pull-rod 3；
4th, equipotential electrician tightens up screw mandrel 4 using electric wrench 19, and four transmission pressure weight, which take a turn for the better, moves in four line hooks 5
On, after waiting insulator chain loose, coordinate No. 1 electrician to carry out the replacing of bunch of insulator.
So, available for the insulator chain for changing different model and different length, the combination tool is easy for installation, operation letter
It is single, power tool is effectively reduced, labor intensity is reduced, operating efficiency and safe operation is improved.
