Abstract
The utility model relates to an electric maintenance device, and the purpose is to provide a link plate clamping tool used to replace a four-split lead duplex strain insulator string. The clamping tool includes a clamping tool main body which is two parallel sheet-type structures. The sheet-type structure includes an obtuse angle-shaped top end, extending sections on the two sides, and two end parts protruding from the tails of the extending sections. The protruding direction of the end parts is opposite to the direction of the top end. In use, the link plate clamping tool is unconstrained by the type of a link plate and can fix the link plate, so the link plate can not rotate when one four-split lead duplex strain insulator string is replaced, and consequently the operation security is improved. The clamping tool can realize the replacement of an entire four-split lead duplex strain insulator string or a single insulator and hardware of the single insulator, thus solving the difficulty which bothers the line overhaul workers. The clamping tool is light, safe, reliable, versatile, and is easy to operate, thus laying the foundation to the popularization and application.
Description
Technical field
The utility model belongs to electric power maintenance equipment, particularly a kind of yoke plate jig that is used to change conductors on quad bundled duplex strain insulator string.
Background technology
The insulation property of insulator are along with the prolongation meeting of service time reduces even complete obiteration gradually, and this phenomenon is called the degradation phenomena of insulator.The glass insulator of deterioration can be revealed, and the appearance of self-destruction insulator has reduced the creepage distance of insulator string, has reduced the insulation level of circuit, might cause the generation of flashover fault.Need in time change the glass insulator of self-destruction to satisfy the requirement of transmission line insulation level for this reason.
Conductors on quad bundled duplex strain insulator string is owing to its particular structure form (the lead side is a duplex plate conductors on quad bundled, and the cross-arm side is a simply connected plate list hanging point), when changing the self-destruction insulator; Receive the restriction of existing Work tool; When tightening up a string insulator string, because two insulator string string unbalance stress can make the yoke plate of cross-arm side produce vertically rotation; Thereby cause pushing between the insulator; And the conductors on quad bundled conductor spacer can deform owing to distortion, has very big security risk, makes that the self-destruction insulator on present this structural shape circuit can not obtain changing.Be necessary to develop a kind of jig of changing conductors on quad bundled duplex strain insulator string that is applicable to for this reason.
The utility model content
The technical problem that the utility model will solve is, provides a kind of simple in structure, in light weight, easy to operate, safe in utilization, is used to change the yoke plate jig of conductors on quad bundled duplex strain insulator string.
Be the technical solution problem, the scheme of the utility model is:
A kind of yoke plate jig that is used to change conductors on quad bundled duplex strain insulator string is provided, comprises the jig main body; Said jig main body is two laminated structures that are arranged in parallel, this laminated structure have the obtuse angle shape top, both sides the extension and in the extension two ends of terminal protrusion, the protrusion direction of end and top in the opposite direction.
As a kind of improvement, be provided with two screws that run through in the middle part of said laminated structure, connect through bolt between two laminated structures.
As a kind of improvement, connect through welding, riveted joint or integral type casting between two laminated structures.
As a kind of improvement, in two ends of laminated structure a screw that runs through is set respectively, and is connected with joint between laminated structure through bolt.
As a kind of improvement, two ends of laminated structure are connected with welding, riveted joint or integral type casting mode with the joint between laminated structure.
As a kind of improvement, on the relative inwall of two laminated structures, be provided with the lines of rule or irregular convexity.
As a kind of improvement, on the middle part of laminated structure and its top opposed edges, be provided with the draw-in groove of an arc.
As a kind of improvement, the thickness of laminated structure middle part is greater than the thickness of extension.
The beneficial effect of the utility model is:
Because special structure design; Can not receive the restriction of yoke plate model when making the utility model use, and can play the fixedly effect of yoke plate, thereby when replacing conductors on quad bundled duplex strain insulator string wherein a string; Can not make yoke plate produce rotation, the fail safe when having strengthened operation.The line maintenance personnel use this jig, can realize the replacing to the whole string of conductors on quad bundled duplex strain insulator string or monolithic insulator and gold utensil thereof, have solved puzzlement line maintenance workman's a difficult problem.Particularly because portability, versatility, ease-to-operate, the security reliability of the utility model jig will be established solid foundation for applying of its.

Fig. 2 be among Fig. 1 A-A to profile;
Fig. 3 is the user mode sketch map of jig.
Embodiment
The yoke plate jig that is used to change conductors on quad bundled duplex strain insulator string in the utility model has through specially designed jig main body 1; There are two demountable joints 2 to be used for matching in addition with it.
Jig main body 1 is two detachable laminated structures that are arranged in parallel, this laminated structure have the obtuse angle shape top, both sides the extension and in the extension two ends of terminal protrusion, the protrusion direction of end and top in the opposite direction.The middle part of jig is provided with two screws that run through, and realizes combination through hex bolts 3; The two ends of extension respectively are provided with a screw that runs through, and make up through hex bolts and joint 2.
Between two laminated structures of jig, and can select between termination and the joint 2 that bolt is connected for use, welding, riveted joint or integral type casting any one connected mode in connecting.What present embodiment was selected for use is that bolt connects, so be provided with fixing threaded hole in the middle part and the two ends correspondence of jig.
The fastening degree of two bolts through regulating the jig middle part just can be fixed in jig on the yoke plate 4 reliably.
In order to increase the frictional force of jig inwall and yoke plate 4, the lines of rule or irregular convexity can be set on the inwall of jig.
Concrete method for using:
Be fixed on reliably on the cross-arm side yoke plate 4 of conductors on quad bundled duplex strain insulator string through two laminated structure cards of hex bolts jig; Respectively two joints 2 are combined to the two ends of jig with hex bolts, the bolt hole through the joint end is connected with two rhizoid thick sticks 5.To have wing formula jig 6 now through being bolted on the lead side yoke plate 7, the screw through wing formula jig two ends is connected with leading screw 5.With two pairs of leading screws yoke plate side jig 4 is connected with lead flank formula jig 6.During use, insulator string is supported, tighten up two pairs of leading screws respectively, make insulator string lax, just can change it with the bottle supporting frame.If combine the enclosed jig, then can change to monolithic insulator and gold utensil.
