Description
Technical field
The utility model relates to the clamping device of outdoor aerial insulation, specifically, relates to a kind of universal jig that overhead transmission line is changed glass insulator that is used for.
Background technology
Fast development along with economic society, the construction speed of overhead transmission line is constantly accelerated, the glass insulator of the different model that a large amount of different manufacturers produce drops into application on the line, even the glass insulator of the same model of same manufacturer production, its steel cap head shapes also irregular, surface are extremely coarse or have a flaw.At present, changing the overhead transmission line glass insulator mainly adopts common jig to cooperate the method for Lever Blocks.The generic card that this method adopts has following defective:
1, the model of common jig must consistently with the model of insulator could be used, and the insulator model of using on the overhead transmission line has thousands of kinds of hundreds ofs, if all buy the jig of respective model at the insulator of every kind of model, must cause huge financial burden to unit.
2, consistent with the glass insulator model common jig is very high to the requirement of glass insulator, and steel cap head is irregular, there be all can not using of any flaw in steel cap head surface.And the steel cap head of glass insulator all is to be cast by the pig iron to form, the steel cap head shapes irregular of same model insulator, the surface is very coarse or have flaw, even also very difficult insulator steel cap head chucking with the common jig of insulator same model, is difficult to finish more changing jobs.
3, the screw mandrel stroke of common jig too short (generally can only block damaged insulator before and after two insulators) causes between the monolithic insulator stuckly mutually easily, and damaged insulator can't take out, and brings huge inconvenience for replacing work.
For in time changing glass insulator damaged in the overhead transmission line, make normally carrying out of trolley wire road service work, developed the universal jig of changing the overhead transmission line glass insulator, this jig can be changed the multi-disc insulator simultaneously, and adaptability is strong, reduces operating personnel's labour intensity, increase work efficiency, the energy one card for multiple uses, the reserve level of minimizing jig is increased economic efficiency.
The utility model content
The purpose of this utility model is to solve the shortcoming that exists in the above-mentioned prior art, provide a kind of simple to operate, need not the universal jig that aid can fastening various models size glass insulator steel cap heads.
For achieving the above object, technical scheme that the utility model adopts is:
A kind of universal jig that is used for overhead transmission line replacing glass insulator, card main body before comprising, back card main body, wherein, go up card and preceding card down before the card main body is respectively equipped with before described, go up the chucking groove that card and preceding card down are respectively equipped with mutual correspondence before described, two chucking grooves of described correspondence form bail wire, described preceding upward card and described preceding cartoon are down crossed the preceding bolt that blocks and are locked and connected, after being respectively equipped with, described back card main body goes up card under card and the back, described back go up card and described back down cartoon block bolt later and lock and connect, described before card main body and back block main body and lock and connect by the double hook wire grip.
Above-mentioned chucking groove diameter size can change by card bolt before regulating or back card bolt.
Further, also be provided with anti-skid structure in the described chucking groove.Described anti-skidding mechanism is mainly used in the insulator steel cap head in the fixing chucking groove.
Again further, described anti-skid structure is the dentation reinforcement.Described dentation reinforcement is to described chucking groove internal projection, and the part of projection is to reserve design at the steel cap head of different-diameter size.The snap action of being convenient to better various different model glass insulator steel cap heads is arranged like this, strengthen the versatility of the utility model structure.
Space between the above-mentioned dentation reinforcement can also hold the irregular part of glass insulator steel cap head and have the part of flaw.
Further, described double hook wire grip is the big stroke screw mandrel of scalable.Described screw mandrel can be regulated length automatically, and the adjustment stroke scope is bigger, can block six insulators of damaged glass insulator front and back when maximum, the phenomenon of effectively avoiding stuck mutually, the damaged insulator between the monolithic insulator to take out, and can easily realize changing the multi-disc insulator simultaneously, increase work efficiency greatly.
Compared with prior art, the beneficial effects of the utility model are: simple to operate, and compact conformation, versatility is very strong, and a kind of universal jig of model can be general to the glass insulator of different manufacturers, different model; The insulator steel cap head that the pole of figure is irregular, the surface is very coarse be can tighten, various steel cap head shapes irregulars, the very coarse insulator in surface adapted to; At every turn multipotency is changed three impaired insulators, has improved operating efficiency greatly.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
If shown in Fig. 1-3, the utility model is a kind of universal jig that overhead transmission line is changed glass insulator that is used for, card main body 1 before comprising, back card main body 2, wherein, before card main body 1 go up card 11 and preceding card 12 down before being respectively equipped with, preceding upward card 11 and preceding card 12 down are respectively equipped with the chucking groove 3 of mutual correspondence, two corresponding chucking grooves 3 form bail wire, before go up card 11 and described before down card 12 lock and connect by preceding card bolt 4, after being respectively equipped with, back card main body 2 goes up card 22 under card 21 and the back, card 22 is by back card bolt 4 ' lock and connect down card 21 and described back on the back, and preceding card main body 1 and back card main body 2 lock and connect by double hook wire grip 5.
Also be provided with anti-skid structure in the chucking groove 3.Anti-skidding mechanism is mainly used in the glass insulator steel cap head in the fixing chucking groove 3.
Anti-skid structure is a dentation reinforcement 6.Dentation reinforcement 6 is to described chucking groove 3 internal projection, and the part of projection is to reserve design at the steel cap head of different-diameter size.The snap action of being convenient to better different model glass insulator steel cap head is arranged like this, strengthen the versatility of the utility model structure.
Space between the dentation reinforcement 6 can also hold the irregular part of glass insulator steel cap head and have the part of flaw.
Double hook wire grip 5 is the big stroke screw mandrel of scalable.Screw mandrel can be regulated length automatically, and the adjustment stroke scope is bigger, can block six insulators of damaged glass insulator front and back when maximum, the phenomenon of effectively avoiding stuck mutually, the damaged insulator between the monolithic insulator to take out, and can easily realize changing the multi-disc insulator simultaneously, increase work efficiency greatly.
Though the utility model illustrates and describes by the reference preferred embodiment, but those skilled in the art should understand, and can be not limited to the description of present embodiment, in the scope of claims, can do the various variation on form and the details.
