Abstract
The utility model discloses a ground wire free of climbing up a pole. The ground wire free of climbing up the pole includes an insulating operating rod (1), a wire clamp (6), a ground wire (2), a ground terminal (4) and a ground terminal screw (3), and is characterized in that: the outside of a connection end between the wire clamp (6) and the insulating operating rod (1) is fixed with a hanging ring which is fixed by the ground terminal (4) and the ground terminal screw (3). Compared with the prior art, the ground wire free of climbing up the pole directly uses the brake pull-rod to hang and remove the ground wire, or use the pulley block to cooperate with the brake pull-rod so as to hang and remove the ground wire, so that the hanging and removing of the ground wire free of climbing up the pole are realized; the time for hanging and removing the ground wire is greatly shortened; the construction time is shortened; the power supply reliability is improved; and the safety for the staff to hang and remove the ground wire is improved.
Description
Technical field
The utility model relates to a kind of electrician's instrument, especially a kind ofly exempts to pedal rod earth wire.
Background technology
In the daily construction working of basic unit's power supply unit, earth connection articulate and dismounting be one very time-consuming, the process of effort, particularly run into the same bar of high-low pressure, when personnel must pass through multilayer line and hang, tear open, will need long time, personnel are also very dangerous.Sometimes a very little job, the actual operating time may only need tens minutes, yet the extension of the earth connection that job site two ends are sealed, tears open and just need twenty or thirty minute, from having affected to a great extent power supply reliability.Therefore, designing a kind of rod earth wire of exempting to pedal, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rod earth wire of exempting to pedal.
The technical scheme in the invention for solving the technical problem is:
Exempt to pedal rod earth wire, comprise insulating bar, wire clamp, earth connection, earth terminal and earth terminal screw, in the outside of the link of wire clamp and insulating bar, with earth terminal and earth terminal screw, be fixed with and exempt to step on rod earth wire operating parts.Described operating parts is one section of angle-shaped piece vertically arranging, on one side of angle-shaped piece, there are two unthreaded holes that vertically arrange, the centre-to-centre spacing of two unthreaded holes is identical with the centre-to-centre spacing of screw hole in wire clamp, on the another side of angle-shaped piece, there is a semiclosed inverse u shape breach, this semiclosed inverse u shape breach enclosure portion upwards has a barb, and this semiclosed inverse u shape breach not width of enclosure portion is greater than the diameter of the cantilever mast of brake pull-rod operating parts.
As a kind of preferred version of the present utility model, on the top of the semiclosed inverse u shape breach of angle-shaped piece, be provided with pulley hanging hole.
As a kind of preferred version of the present utility model, other exempts to pedal the cross-arm of rod earth wire on insulating bar, to be fixed with suspension.
Compared with prior art, the utility model is directly used brake pull-rod extension, dismounting ground wire, or use assembly pulley to coordinate brake pull-rod extension, dismounting ground wire, bar extension, dismounting ground wire have been accomplished to exempt to pedal, greatly shorten articulating and the dismounting time of earth connection, shorten the engineering time, improve power supply reliability, the fail safe of raising personnel when hanging dismounting ground wire.
