Background technology
Interruption maintenance operation is one of Maintenance of Electric Transmission Line line facility conventional means of normally moving, ensureing the normal electricity consumption of resident always.In interruption maintenance operation, for preventing the unsafe conditions such as incoming call or induced electricity electric shock suddenly, must hang at the two ends of job site main earth connection carries out short circuit, guarantees operating personnel's personal safety.The economic loss of bringing for reducing interruption maintenance operation, alleviates operating personnel's work load, just must shorten the line outage repair time.Hang the time of main earth connection and improve the disposable success rate hanging of main earth connection and just can reduce to a certain extent the interruption maintenance activity duration if can shorten.The maintenance of line outage at present, mainly hangs main earth connection by insulating bar, has following problem but use existing action bars to hang main earth connection:
1, insulating bar (becket) is easy to come off from the groove of main earth connection chuck.
2, can only adopt vertical hanging formula earthing method, hang main earth connection difficulty large for the shaft tower of extreme terrain and strain insulator corner, the degree of freedom of operating personnel's operation is not high.
3, in particular cases, use current insulating bar effective length partially short
4, carrying out that three-phase drainage thread is torn open, in joining seam operation, due to line direction reason, to cause hanging main electrical scheme work difficulty large.
5, after having hung, in the time that action bars departs from from the wire clamp groove of main earth connection, hook-type spring wire clamp is pulled open, cause connecting without reliable, need again hang, the disposable success rate hanging is lower.
Summary of the invention
To be solved in the utility model is the problem that prior art exists, and aims to provide a kind of simple in structure, practicality and high efficiency, flexible and convenient operation, the disposable insulating bar of main earth connection and the jockey of main earth connection of successfully hanging when being suitable for line outage and overhauling.
For addressing the above problem, the utility model is by the following technical solutions: the jockey that improves main earth connection and hang timeliness, comprise connecting pin and lower connecting pin, it is characterized in that, the top of described upper connecting pin offers insulating bar link slot and upper installing hole, the bottom of described upper connecting pin is provided with pin-and-hole, in described pin-and-hole, is provided with steady pin; Described lower connecting pin is tubular structure, and bottom is provided with main earth connection link slot and installing hole; The top of described lower connecting pin offers ear groove; The top of described lower connecting pin is inserted in the bottom of described upper connecting pin, and described connecting pin is placed in described ear groove.
Jockey for main earth connection and insulating bar of the present utility model, when use, is fixed upper connecting pin to be connected with insulating bar by bolt or pin, and lower connecting pin is connected with the groove of main earth connection wire clamp with bolt or pin.When operation, main earth connection wire clamp is clamped wire by hand-held insulating bar, can overhaul.Because the utility model can once successfully hang the main earth connection of various towers, improve and hung efficiency, shorten the time of hanging, and then shortened the interruption maintenance activity duration, reduce the economic loss that has a power failure and bring.And, due to the utility model tool operation light and flexible, low to operating personnel's operating technology requirement, be easy to large scale application.
As further improvement of the utility model, in the body of described lower connecting pin, there is a confined planes, on described confined planes, be also provided with spring, lower connecting pin is connected by Clothoid type spring together with insulating bar with upper connecting pin together with main earth connection, can make like this insulating bar and main earth connection be linked to be an entirety, can dismantle very easily again separation simultaneously.
Further improve as of the present utility model, described upper connecting pin comprises pedestal and two-stage boss again, and described pin-and-hole is arranged on the first order boss being connected with described pedestal.
Further improve as of the present utility model, described ear groove is a pair of, and is symmetricly set on the top of described lower connecting pin again, upper and lower connecting pin is connected more reliable, operates more steady.
Further improve as of the present utility model, described connecting pin up and down all adopts bolt or pin to be connected with existing equipment again, has ensured the tight connected of main earth connection, connecting pin, insulating bar, does not rock all parts one integrated mass after stressed.
Further improve as of the present utility model, described upper connecting pin and existing insulating bar are bolted again, and can multi-angle regulate upper connecting pin, and convenient operation personnel face site environment complexity, hang the not good situation in position.
Further improve as of the present utility model, described connecting pin up and down adopts alloy material solid forging, and the overall pipe wall thickness 1.5mm of described lower connecting pin, alleviates jockey weight.
