Description
Technical field
The utility model belongs to a kind of instrument, particularly a kind of grounding wire clip using in high-tension line maintenance.
Background technology
In the time that high-tension line keeps in repair, in order to prevent that operating personnel from induced electricity occurring and wound, must, by ultra-high-tension power transmission line reliable ground, link together with the wire that is flexible coupling by transmission pressure and shaft tower, by transmission pressure safety ground, to guarantee operating personnel's personal safety.At present, the wire that is flexible coupling using in engineering has 6 ~ 7 meters long conventionally, be flexible coupling one end of wire is provided with a clamp, the other end is provided with a grounding wire clip, clamp is fixed on shaft tower, grounding wire clip is clipped on transmission pressure, thereby transmission pressure and shaft tower are linked together, and realizes safety ground.Existing grounding wire clip is similar to people's typical clamp used in everyday, just many support bars, and support bar one end is hinged on an intermediate plate, and one end is supported on another intermediate plate.When use, grounding wire clip is suspended in to the top of transmission pressure, then, fast to transferring grounding wire clip, utilizes the weight of grounding wire clip itself to rush open support bar, grounding wire clip is clipped on transmission pressure.The subject matter that this grounding wire clip exists is: can only use in the vertical direction of transmission pressure, use inconvenience, inefficiency.In addition, the spring of grounding wire clip is thinner, and clamping force is less, works unreliable, and in the process using, easily loosening or disengagement, causes potential safety hazard.
Chinese patent 201020580465.6 discloses a kind of grounding wire clip, and it is made up of clamp holder, chuck, spring, support chip and two supporting pins.Be provided with a through hole in the upper end of clamp holder, be used for being connected with the wire that is flexible coupling, chuck is hinged on clamp holder, and spring fitting, in the hinged place of clamp holder and chuck, has the through hole of a rectangle on chuck, two supporting pins are arranged in rectangular through-hole, support chip is hinged on clamp holder, and is arranged in the through hole of chuck, also has two supporting mouth on support chip, two supporting mouth match with two supporting pins respectively, are grounded the folding of harness clip by lifting the wire that is flexible coupling.This grounding wire clip can use in the place of departing from transmission pressure, and easy and simple to handle, and clamping force is large, safe and reliable.But the clamp holder of this grounding wire clip is to link together by terminal block screw bolt and nut with the wire that is flexible coupling, terminal block first together with the conductor compression jointing that is flexible coupling, then is fixed on terminal block on the through hole of clamp holder with screw bolt and nut.The problem that this connected mode exists is: terminal block is positioned at a side of clamp holder, lift while being flexible coupling wire, the stress point of clamp holder is not on the center line of clamp holder, but in a side of clamp holder, lift the deflection that can cause clamp holder while being flexible coupling wire, in use there will be the phenomenon of clamping stagnation, thereby affect the normal use of grounding wire clip.In addition, the folding of grounding wire clip realizes by lifting the wire that is flexible coupling, this does not meet the working specification of transmission line on the one hand, also can cause certain infringement to the wire that is flexible coupling on the other hand, and the problems such as appearance between wire and terminal block is become flexible, disengagement that cause being flexible coupling, the useful life of reducing the wire that is flexible coupling.
Summary of the invention
The purpose of this utility model is to overcome the problem that above-mentioned grounding wire clip exists, and a kind of easy to use, failure rate is low, durable in use, the grounding wire clip that meets specification are provided.
The utility model comprises clamp holder, chuck, spring, support chip and two supporting pins, chuck is hinged on clamp holder, spring fitting is in the hinged place of clamp holder and chuck, on chuck, there is a rectangular through-hole, two supporting pins are arranged in rectangular through-hole, support chip is hinged on clamp holder, and be arranged in the rectangular through-hole of chuck, its special character is, there is a screw hole at the top, upper end of clamp holder, connecting bolt is installed in screw hole, on connecting bolt top, the wire that is flexible coupling is installed, on wire, there is insulated tube being flexible coupling, a connecting plate is also installed between connecting bolt and clamp holder, a wiring clamp is installed on connecting plate, insulation stay cord is installed on wiring clamp, insulation stay cord is fixed together with the wire insulating sleeve that is flexible coupling.
The utility model has the advantage of:
1, be flexible coupling wire and insulation stay cord all in clamp holder top center, while lifting insulation stay cord, the stress point of clamp holder is just in time on the center line of clamp holder, therefore, while lifting insulation stay cord, can not cause the deflection of clamp holder, stop the catching phenomenon in use procedure, greatly improve the reliability of operation, thereby guarantee the normal use of grounding wire clip, the probability having broken down while having reduced operation, and use convenient.
2, at clamp holder top, insulation stay cord is set, when operational grounding harness clip, needn't lift the wire that is flexible coupling, only need lift insulation pulling cord, this has met the working specification of transmission line on the one hand, also the wire of having avoided being on the other hand flexible coupling suffers damage, and has extended the useful life of the wire that is flexible coupling.
3, on wire, insulated tube is set being flexible coupling, has avoided operating personnel directly to contact with the wire that is flexible coupling, use more safe and reliable.
4, insulation stay cord is fixed together with the wire insulating sleeve that is flexible coupling, and has guaranteed can not cause while lifting insulation stay cord the deflection of clamp holder, has further improved the reliability using.
