In normal power circuit and custom power overhaul of the equipments work, often run into the situation that to take power cable and overhead transmission line jointing apart.At this moment; should on power cable head (cable nose), do safety measure; reason is: although the cable end of the user side that disconnects dead electricity; but a lot of users have the generator of providing for oneself; if self power generation during this period; the cable end of these disconnections will be charged, and then crisis maintainer's life security.Mostly be the vertical direction setting greatly owing to enter the power cable head at user place, it can not bear gravity, and ground wire has certain weight, makes that the cable nose is difficult to support the weight of ground wire.For this reason, when running into similar state, the maintainer is powerless to this, be mostly the user side cable end of leaving to take apart under the situation that does not add any safeguard procedures, exposed outside.At present, common earth connection peg, mouth hanging is a level, can not adapt to such environment for use, can't add hanging earthing conductor on the end of a thread, line nose power cable head up.
The utility model content
The utility model is at above problem, and providing a kind of can add hanging earthing conductor on the end of a thread, line nose power cable head up, thereby guarantees the cable end grounding wire device of maintainer's safety.
The technical solution of the utility model is: comprise earth connection, the insulation wire clamping head device that it also comprises bracing frame, flexibly connects with bracing frame; Described bracing frame is fixedly connected on the electric pole of service cable; Described insulation wire clamping head device comprises insulating bar, clamp head, the open-and-close mechanism of hollow; The clamp head comprises body, fixture block, the c-shaped shape of body, and the horizontal direction setting, fixture block is arranged in the recess of C shape body, and can move with respect to body; Open-and-close mechanism comprises spring, guide rod, soft rope, pull bar, crank mechanism; Body links to each other by elbow with insulating bar, is 45~160 ° of angles each other, and guide rod is fixedly connected on the fixture block back side, and spring is arranged on the guide rod between fixture block and the body; Guide rod is fixedly linked by soft rope and the pull bar that is arranged in the insulating bar after stretching into elbow; Crank mechanism is arranged on the insulating bar bottom, comprises crank-type spanner, spanner support, and the spanner support is arranged on the insulating bar outside, and insulating bar and hinged with pull bar is run through at crank-type spanner middle part, and fulcrum is decided in staight shank end and the hinged formation of spanner support, and earth connection connects body.
Described elbow is universal elbow.
The corresponding surface of described body, fixture block is provided with rubbing surface.
The clamp head of this novel cable end grounding wire device provided by the utility model is under the effect of open-and-close mechanism, can be reliably with the cable end or the Wiring nose clamping of vertical direction, during operation, only need pull the crank-type spanner of open-and-close mechanism, by pull bar, soft rope, guide rod, overcome spring from the fixture block back side apply one make the pressure that fixture block is positive with intrinsic corresponding end face fits tightly under normal conditions after, the positive corresponding inner face with body of fixture block is separated, thereby cable end can be stretched in the space separately; After unclamping the crank-type spanner, the positive and intrinsic corresponding end face of fixture block is fitted, thereby cable end is clamped.Ground wire is connected on the body of metal, guarantees to be connected with service cable head conduction.Bracing frame on supporting the be fixed on electric pole is used for each cable end grounding wire device is supported in the air.The utility model has solved an insoluble always difficult problem that exists in the prior art, even the anti-electricity that send of user, also entail dangers to maintainer's safety not.The utility model exquisite composition, the reliability height.
