Background technology
As 500kV transmission lines of electricity power grid construction input increases, still face to pass through at present and road is built below 500kV circuits
The engineerings such as road, railway, circuit are on the increase, and arrange regulation according to south net is counter, for raising circuit safety in operation, 500kV need to be related to
And scissors crossing section carries out single suspension insulator and is changed to double suspension insulators.Traditional work method be using cucurbit or
Shifted again after lifting insulator by stress hanging point, but the method is in use, since cross-arm structure is different, often
Need to adjust in suspension centre selection, angle etc. multiple, suspension insulator could be displaced to new hanging point, to making during this
Level of skill, method and body strength of industry personnel etc. are proposed higher requirement, if shifted for a long time less than new
Hanging point, can also greatly increase operating risk.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of 500kV transmission lines of electricity list suspension insulator and replaces
Gearshift is lifted for double insulator string, the endurance of insulator chain is transferred on cross-arm and device by the device, and profit
Its displacement function is realized with the roller on device, moves into new hanging point, and it is easy to operate, operating efficiency is improved, reduces operating risk.
The utility model solves above-mentioned technical problem with following technical solution：
The utility model 500kV transmission line of electricity list suspension insulators are changed to double insulator string lifting gearshift, bag
Include slotted body and two leading screws, downward, and lower middle portion is provided with the notch of slotted body can avoid insulator hanging point spiral shell
The inverted U-shaped recess of bolt, slotted body are provided with the roller that body can be driven to move by wheel shaft；Two leading screws pass through flute profile sheet
Body, and lower part is equipped with the fixture block of two leading screws of connection and insulator pin, the top of two leading screws is respectively equipped with realization tightening
Or stretch out the revolving rod of leading screw.
The fixture block is made of two pieces of intermediate plates, and two pieces of intermediate plates pass through screw connection.
At least provided with two, the wheel shaft for installing roller is fixed in slotted body the roller.
The utility model 500kV transmission line of electricity list suspension insulators, which are changed to double insulator string lifting gearshift, to be had
Following advantage：
1st, using the tightening campaign of the leading screw on device, the endurance of insulator chain is transferred on cross-arm and device, is grasped
Make simple.
2nd, the problems such as being translated using the roller on device, being displaced to new hanging point, effectively avoided because of angle can not be new
Hanging point position penetrates the problem of bolt.
3. the utility model can effectively mitigate operating personnel's load, of less demanding to operating personnel's level of skill, can
For generally operating, operating efficiency is improved, reduces operating risk.

Embodiment
The utility model will be further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model 500kV transmission lines of electricity list suspension insulator is changed to double insulator string
Lifting gearshift is mainly made of slotted body 4 and two leading screws 5, the notch of slotted body 4 downward, and lower middle portion
The inverted U-shaped recess of insulator hanging point bolt can be avoided by being provided with, and the both ends of slotted body 4 are provided with by wheel shaft 3 can drive respectively
The roller 2 of body movement, wheel shaft 3 are fixed in slotted body 4；Two leading screws 5 pass through the middle part of slotted body, and lower part is equipped with
For connecting the fixture block 6 of two leading screws 5 and insulator pin 8, the top of two leading screws 5 is respectively equipped with realization tightening or stretchs out
The revolving rod 1 of leading screw；Fixture block 6 is made of two pieces of intermediate plates, passes through screw connection between two pieces of intermediate plates.
Roller described in the utility model can set two or more.
As shown in Fig. 2, the slotted body 4 of the utility model is mainly arranged at 500kV (220kV) insulators hanging point horizontal stroke
Carry on a shoulder pole on 7 position, the inverted U-shaped recess that lower section opens up among slotted body 4, is mainly used for without prejudice to insulator hanging point bolt
Dismount work.
During operation, 8 position of insulator chain first insulator bulb first is blocked with fixture block 6, while fixture block 6 connects two silks
Thick stick 5, then rotates rotating rod 1, leading screw 5 is made tightening movement, is carried fixture block 6 and bunch of insulator by upward active force
Rise, insulator hanging point bolt is in and does not stress state at this time, operating personnel so as in the position of inverted U-shaped recess by insulator
Hanging point disassembling bolts, 4 both ends of slotted body are connected with two rollers 2 by wheel shaft 3, after insulator chain is raised, operation people
Member is by flat-pushing whole device, and using the rotational displacement of roller 2 at new hanging point, operating personnel penetrates spiral shell in new hanging point position
Bolt, rotates backward rotating rod 1, loosens leading screw 5 downwards, the gradual stress of insulator hanging point bolt, after complete stress, removes folder
Block 6, displacement are completed.
Since part 220kV iron tower of power transmission line insulator hanging point cross-arms are similar with 500kV, so the utility model
500kV transmission line of electricity list suspension insulators are changed to double insulator string lifting gearshift, and to be equally also suitable part 220kV defeated
Electric line list suspension insulator is changed to double insulator string operation.
