Description
Technical field
The present invention relates to a kind of insulator string charged for replacement operation technique, particularly LF type link plate clamping tool for a kind of 220kV line insulator string charged for replacement.
Background technology
L-LF pattern refers to the assembly type of insulator string, and what the gold utensil at 220kV line tension duplex insulator two ends adopted is that L-type yoke plate and LF type yoke plate coordinate installation.LF type yoke plate title is rectangle yoke plate, and it applies extremely many on the line, but various informative, is mainly reflected in: rectangular slab, except four angles are connected with gold utensil, are also divided into and have handle hole and without handle hole, have hollow out and there is no hollow out on plate face.For hollow out pattern person, be also divided into two kinds of patterns of oval hollow out and circular hollow out.What the present invention is directed to is oval hollow out pattern LF type yoke plate, and it is to be mainly directly connected with double bundle conductor that side of wire was adopts the advantage of LF type yoke plate, need not additionally increase yoke plate, reduces the consumption of material.
Yet 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.To maintenance, bring very big inconvenience 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 object of the invention is to overcome the deficiencies in the prior art part and provide a kind of simple to operation, simple in structure effective, reduce workload, LF type link plate clamping tool for the 220kV line insulator string charged for replacement of increasing work efficiency.
The object of the invention is to realize by following approach:
LF type link plate clamping tool for 220kV line insulator string charged for replacement, its structural feature is, include yoke plate side part and insulating bar side part, yoke plate sidepiece is divided into a kind of curved arc shape overturning plate clamp, include fixed page and active page, wherein fixed page and insulating bar sidepiece are divided into Construction integration, and one end and the fixed page of active page are hinged, and can be locked by screw rod; First curved arc that described fixed page and active page start to extend forward from hinged place is provided with the connecting hole of lateral direction penetrating, and this connecting hole is adaptive with the nut being arranged on LF type yoke plate, and nut can just in time wear this connecting hole; Second curved arc that described fixed page and active page start to extend forward from hinged place is jig head, and it is provided with the pin-and-hole laterally running through that can connect bayonet lock; In insulating bar side part, be provided with handle hole, it can be connected with insulated tension pole.
Pin-and-hole and the distance between connecting hole of curved arc shape overturning plate clamp are: in the time of on the nut below connecting hole is set on LF type yoke plate, the below tangent line of pin-and-hole is just in time positioned on yoke plate along on limit.It is first strong point that described like this link plate clamping tool just be take the socket of connecting hole and nut, and the shear force along limit is second strong point on pin-and-hole and yoke plate, the active force of two strong points is contrary, make lifting insulating bar, when carrying in insulating bar side part, can under the effect of this two strong point, will in the respective side of LF type yoke plate, carry the insulator string that relaxes, complete replacing operation.Described link plate clamping tool is when operation, need operating personnel to enter electric field and carry out equipotential operation, open active page, fixed page is leaned against on the nut of wherein one side below of yoke plate, the connecting hole in fixed page is set on this nut, active page closes, the nut of yoke plate opposite side is also inserted on the connecting hole of active page, finally adjusts link plate clamping tool, the pin-and-hole of head is exposed on LF type yoke plate along limit, and insert bayonet lock, complete fixing; Finally insulation sides part is coupled together with insulated tension pole, complete link plate clamping tool is arranged on LF type yoke plate, finally by lifting link plate clamping tool under existing wire grip effect, lax insulator string.
It is critical support point with the tie point of yoke plate nut that the present invention be take in the middle of jig, and simple to operation, workload is little, and operating efficiency is high, has effectively improved the ability of live line working abatement apparatus defect, reduces the line outage time, improves the reliability of operation of power networks.
The present invention can further be specially:
The pin-and-hole place of curved arc shape overturning plate clamp head is horizontally arranged with guide, and bayonet lock is arranged in this guide.
In guide, be provided with spacing to bayonet lock 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 hinge portion of fixed page and active page includes connecting axle and tie down screw, and described tie down screw is between fixed page and active page, and it can just in time abut in the short brink of yoke plate when link plate clamping tool is connected on LF yoke plate.
Like this, the reverse strong point when screw rod of locking hinge also can be used as link plate clamping tool work, contributes to stable connection and the operation of link plate clamping tool.
Insulating bar side is partly a kind of solid component, and it intersects and tight joint by handle hole and insulated tension pole.
Or: insulating bar side is partly 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: insulating bar side is partly 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.
By connecting pin, realize insulating bar side part and be connected with insulated tension pole twisted branch, thereby can guarantee insulated tension pole link plate clamping tool swing relatively, make operation process convenient.
In sum, the invention provides LF type link plate clamping tool for a kind of 220kV line insulator string charged for replacement, take in the middle of jig with the tie point of yoke plate nut as critical support point, jig is designed, adopt the structure of turnover panel cassette, simple to operation, workload is little, and operating efficiency is high, has effectively improved the ability of live line working abatement apparatus defect, reduce the line outage time, improve the reliability of operation of power networks.
