Description
Technical field
The invention belongs to power industry livewire work service kit.
Background technology
In recent years, society's electricity consumption amount is continuously increased, in order to not influence the normal electricity consumption of users, power transmission lines overhauling dimension
Shield is more to carry out defect elimination using the operating type not having a power failure.For charged for replacement 220kV triangle yoke plate two strings of strain insulators, have specially
Broadsword fixture, the broadsword fixture that intermediate insulation arm-tie connection both sides are snapped on triangle yoke plate during equipotential live line work,
Tightened up by screw mandrel to change insulator chain.But for using the double strings of strain insulator of LF type yoke plates on 220kV circuits, do not have
There is special mould clamp.In real work, it can only have a power failure and change insulator chain after both sides yoke plate is tightened up using Lever Blocks, it is time-consuming
The power supply reliability of power network is also reduced while laborious.
The content of the invention
The purpose of the present invention is exactly to overcome above-mentioned difficulty, and thinking is obtained from monolithic insulator special mould clamp is changed,
Design the live replacement of 220 kV tension-resistant double insulator string LF yoke plate special mould clamps appeared in.The present invention can realize charged for replacement
Using the double strings of strain insulator of LF yoke plates on 220kV transmission lines of electricity.
Live replacement of 220 kV tension-resistant double insulator string LF yoke plate special mould clamps, including main base connect with by pin
Connecting rod in main base bottom, agent structure side are connected with pedestal；Wherein, main base is a cuboid, in
Portion offers Baltimore groove and is used to be anchored to yoke plate；The key seat with prominent ears structure is arranged with main base two bottom sides,
Four key seats are connected with two connecting rods respectively by pin, it is blocked yoke plate；Pedestal is one and main base upper surface
Parallel triangle harden structure, the triangle groove for mitigating weight is offered in the triangle harden structure, head end is provided with outside pedestal
Hangers is used to be connected with insulation pulling plate.
In the course of work, fixture main base is anchored on LF yoke plates, by prominent with band after two connecting rods installation pins
The key seat of ears structure is connected, and yoke plate is blocked with this.The hangers of the outer head end of pedestal is connected with insulation pulling plate, insulation pulling plate
Opposite side connects broadsword fixture, changes insulator chain by tightening up screw mandrel, improves operating efficiency, has ensured the safety of power network
Stability.
The principle of the invention is similar with changing monolithic insulator special mould clamp principle, and in the course of work, fixture main base is buckled
Onto LF yoke plates, by being connected after two connecting rods installation pins with the key seat with prominent ears structure, joined with this to block
Plate.The hangers of the outer head end of pedestal is connected with insulation pulling plate, and insulation pulling plate opposite side connects broadsword fixture, by tighten up screw mandrel come
Insulator chain is changed to realize on charged for replacement 220kV transmission lines of electricity using the two strings of strain insulators of LF yoke plates.
The beneficial effects of the present invention are：Solve 220kV transmission lines of electricity to go here and there more using LF type yoke plates strain insulator is double
Change jobs no special mould clamp, and can only have a power failure the difficulty changed using Lever Blocks.This effectively utilizes yoke plate both sides using new
As fulcrum force, by effective connection between fixture, screw mandrel, insulation pulling plate, it is efficiently transferred to the power on insulator chain
On Work tool used, insulator is changed by tightening up screw mandrel, to reach the purpose for changing insulator chain, reduces line outage
Time, add power supply reliability.
