Parallel groove clamp assembly and disassembly operations instrument
Technical field
The present invention relates to a kind of power equipment mounting and dismounting tool, more particularly to a kind of parallel groove clamp assembly and disassembly operations instrument.
Background technology
Parallel groove clamp is a kind of for the parallel wire that continues, the contact gold utensil of transmission electrical load, using widely.It is non-
Wire jumper, the T wiring of power system non-bearing junction, the branch line of straight line pole, the electrical equipment downlead such as switch, transformer,
Ground wire grounding downlead etc. is continued, and parallel groove clamp can be used to complete.
At present, drawing for 10kV distribution network lines new equipment connects that to take fire be all to take fire using power failure, fewer to use equipotential band
Electricity takes fire, and earth potential live is taken fire and also just started to walk.If can be new using common parallel groove clamp band electrical bonding, realization for ground potential
Equipment live introduces system, then can overcome need to take power failure to take fiery mode and increase supply line's frequency of power cut originally, improves and supplies
Electric reliability, reduction delivery loss.
The content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of parallel groove clamp assembly and disassembly operations instrument,
It can realize that earth potential live takes fire by common parallel groove clamp using inventive article.
To achieve these goals, the present invention uses following technical scheme:It includes the parallel groove clamp being arranged in main body
Posting, the lowering or hoisting gear being connected with the parallel groove clamp posting;Main body is in edge-on concave shape structure, and its front offers many
Individual chute;The parallel groove clamp posting by the lifter plate in main body, be articulated in respectively the lifter plate both sides spring forceps,
The positive pressing plate of lifter plate is arranged on by elastic device, constituted with the sleeve installing plate that lifter plate is connected, the sleeve installing plate
On be fixed with multiple sleeves, the back side of each sleeve through corresponding chute from main body is stretched out;The lowering or hoisting gear is by being fixed on master
The adapter sleeve of body bottom, the insulating sleeve being flexibly connected by attachment means with the adapter sleeve, it is fixed in the insulating sleeve
Nut, the screw rod composition for being upward through main body with merging with the nut and being contacted with lifter plate;The positioner is by being fixed on
Body top two wires mounting locating piece, respectively be located at each sleeve both sides and be fixed on sleeve installing plate it is positive it is multiple simultaneously
Ditch wire clamp locating piece is constituted.
The elastic device is arranged in lifter plate by two ends and stage casing bends to the expansion link of L shape structures, is respectively mounted
Holddown spring at the expansion link two ends, is separately fixed at expansion link two ends and holddown spring is pressed on to the regulation in lifter plate
Nut is constituted;Expansion link is pressed on the front of lifter plate through pressing plate.
The attachment means are arranged on insulating sleeve by multiple balls on the insulating sleeve tube wall, by jump ring
The surface and overcoat, the spring between the overcoat and insulating sleeve that compress the ball are constituted, in the appearance of adapter sleeve
There is the annular groove being adapted with ball in face.
Lifter plate is arranged in main body by two guide pillars.
Compared with the prior art, therefore the present invention by adopting the above-described technical solution, have simple in construction, easy to operate
The advantages of, user's report can be shortened safe and efficiently using common and hook wire clamp and realize that earth potential live takes fire by being not required to power failure
ETL estimated time of loading.

Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1~5:Main body 13 is in edge-on concave shape structure or edge-on channel steel shape structure, by insulating materials system
Into;Its front offers multiple chutes 15.There are parallel groove clamp posting and positioner in main body 13, there is liter the lower section of main body 13
Falling unit.Wherein:
The parallel groove clamp posting by the lifter plate 8 in main body 13, be articulated in the bullets of the lifter plate both sides respectively
Spring pincers 3, the structure of sleeve installing plate 10 being fixedly connected by elastic device installed in the positive pressing plate 4 of lifter plate 8, with lifter plate 8
Into being fixed with multiple sleeves 11 on the sleeve installing plate, the back side of each sleeve 11 through corresponding chute 15 from main body 13 is stretched out.
Spring forceps 3 by be articulated in by bearing pin (not indicated in figure) on lifter plate 8 two calipers (not indicated in figure), will be described
The torsion spring 9 that the jaws of two calipers is compressed is constituted, and the effect of spring forceps 3 is to connect wire and be fixed on parallel groove clamp drawing for new equipment
It is interior, to prevent it from slipping.The positioner is by being fixed on two wire hanging wire locating pieces 1 at the top of main body 13, being located at respectively
Each both sides of sleeve 11 are simultaneously fixed on the positive multiple locating pieces 2 of sleeve rack 10 and constituted.The lowering or hoisting gear is by passing through flanged plate 14
The adapter sleeve 18 that is fixed on the bottom of main body 13, the insulating sleeve 6 being flexibly connected by attachment means with the adapter sleeve, it is fixed on this
Nut 17 in insulating sleeve, constitute with the screw rod 7 for being upward through main body 13 and being contacted with lifter plate 8 is merged with the nut.
Lifter plate 8 is hollow core structures, and the elastic device is stretched into lifter plate 8 by two ends and stage casing bends to L shapes sky
Between structure expansion link 5, be separately mounted to the holddown spring 19 at the expansion link two ends, be separately fixed at the expansion link two ends and will
The adjusting nut 20 that spring 19 is pressed in lifter plate 8 is constituted, and the stage casing of expansion link 5 is pressed on lifter plate 8 through pressing plate 4
Front.
The attachment means are arranged on insulating sleeve 6 by multiple balls 22 on the tube wall of insulation tube 6, by jump ring
The overcoat 16 on surface, the spring 21 between the overcoat and insulating sleeve 6 are constituted, and are had and ball on the surface of adapter sleeve 18
Ball 22 is pressed in the annular groove by 22 annular grooves being adapted (not indicated in figure), overcoat 16.
In order to realize that parallel groove clamp is accurately positioned, lifter plate 8 is arranged in main body 13 by two guide pillars 12.
In use, first held out against parallel groove clamp (not shown) on sleeve installing plate 10 by pressing plate 4, it is described
The lock-screw (not shown) and nut (not shown) of parallel groove clamp and the ratchet carriage being installed in sleeve 11
The concentric simultaneously fit of spanner (not shown), pre-terminated wire (not shown) is clamped and is stably held in simultaneously by spring forceps 3
In the lower groove (not shown) of ditch wire clamp, rotating edge sleeve pipe 6 using insulating bar (not shown) can be pushed away by screw rod 7
Dynamic lifter plate 8 is moved upwards along guide pillar 12, until live wire (not shown) enters the upper groove of parallel groove clamp (in figure not
Show) in, now keep instrument stable;Described ratchet carriage is operated to pull using an other insulating bar (not shown)
Hand, makes screw, the nut fastening of parallel groove clamp.Rotating backward edge sleeve pipe 6 can drive lifter plate 8 to decline by screw rod 7, until
Spring forceps 3 departs from wire, so that implementation tool is threaded off.
