But the design feature of the type yoke plate is: yoke plate dimensional space is little, is connected gold utensil, bolt, spring catch and has occupied most of space.Bring very big inconvenience to maintenance like this, especially live line working is difficult to effectively carry out especially, existing jig or need LF type yoke plate that enough fixing point or tie points are provided, the operating point that needs to provide abundant on instrument is to realize and being connected and fixing of yoke plate, therefore all cannot on LF type yoke plate, connect and fix, the fastening means that also needing of having provides auxiliary, makes workload large, and operating efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part and provides a kind of simple to operation, simple in structure effective, reduces workload, the front card of LF pattern insulator string charged for replacement operation of increasing work efficiency.
The purpose of this utility model realizes by following approach:
The front card of LF pattern insulator string charged for replacement operation, its structural feature is, described front card is a kind of L-type jig, comprise the stub being connected with yoke plate, and the long card being connected with insulated tension pole, stub is a kind of opening fork-shaped card, the end of fork-shaped card is provided with the pin-and-hole laterally running through that can connect bayonet lock, the fork pockets width of fork-shaped card and LF type yoke plate adaptation, can sleeve on LF type yoke plate; On long card, be provided with connecting hole, and by this connecting hole be arranged on LF type yoke plate on the gold utensil connection that is connected with wire; The tail end of long card has insulated tension pole connecting portion.
When use, enter electric field by operating personnel and carry out equipotential and operate, by the stub of L-type jig from LF type yoke plate along limit to upper sleeve, and pin-and-hole is adjusted in the slotted eye in LF type yoke plate, then insert bayonet lock, complete being connected of L-type jig and LF type yoke plate; Subsequently the connecting hole on long card is aimed to vacant through hole on gold utensil, and connect upper bolt, make it to be fixed on gold utensil.Like this, L-type jig taking long card with the tie point of gold utensil as the strong point, and taking the tie point (bayonet lock) of stub and LF type yoke plate as the anti-strong point, realize the front installation blocking.
Main points of the present utility model are, flexible utilization vacant through hole on the slotted eye on LF type yoke plate and the shaft-like gold utensil between yoke plate and wire come spacing and be connected L-type jig, so that the strong point of operation to be provided, because the distribution of yoke plate and shaft-like gold utensil is at right angles constructed, L-type jig can form quadrangle structure with this right angle configuration, become a firm structure, be convenient to operation, make the L-type jig can be simply and effectively, in operation, become simple, convenient, greatly reduce work operations amount, improve operating efficiency, effectively improve the ability of live line working abatement apparatus defect, reduce the line outage time, improve the reliability of operation of power networks.
The utility model can further be specially:
The pin-and-hole place of stub is horizontally arranged with guide, and bayonet lock is arranged in this guide.
In guide, be provided with bayonet lock spacingly and prestressed spring and limit component are provided, bayonet lock is arranged in guide, and realizes the action of extracting therein and regaining, and bayonet lock end arranges connecting ring, so that operate with action bars.
The fork pockets bottom of stub is an inclined-plane, is positioned at the medium position of stub, and it,, in the time that stub cover is inserted on LF type yoke plate, can be attached to the lower to limit of LF type yoke plate.
Like this, in the time that stub cover is inserted on LF type yoke plate, can better stablizes it and connect effect, ensure the stability of operation.
Insulated tension pole connecting portion is a kind of opening fork-shaped, and fork pockets thickness is greater than the thickness of insulated tension pole, is laterally penetrated with a kind of connecting pin and can be plugged on handle hole wherein on the fork wing.
Or: insulated tension pole connecting portion is a kind of opening fork-shaped, and fork pockets thickness is greater than the thickness of insulated tension pole, and the connecting pin that on the fork wing, end face is laterally penetrated with on a kind of insulated tension pole can twisted branch groove therein.
Realize insulating bar side part by connecting pin and be connected with insulated tension pole twisted branch, thereby can ensure insulated tension pole link plate clamping tool swing relatively, make operation process convenient.
In sum, the utility model provides a kind of 220kV circuit LF pattern insulator string charged for replacement operation front card, flexible utilization vacant through hole on the slotted eye on LF type yoke plate and the shaft-like gold utensil between yoke plate and wire come spacing and be connected L-type jig, so that the strong point of operation to be provided, make the L-type jig can be simply and effectively, in operation, become simple, convenient, greatly reduce work operations amount, improve operating efficiency, effectively improve the ability of live line working abatement apparatus defect, reduce the line outage time, improve the reliability of operation of power networks.
