Abstract
The invention relates to the field of electrical maintenance, in particular to a mounting tool for a fitting bolt and a ground potential nut. The mounting tool comprises an insulating rod and a nut mounting head. The insulating rod includes a mounting base which is located at the front end of the insulating rod, and the mounting base is of a disc structure; gear teeth and grooves are formed in the circumferential edge of one plane of the mounting base and arranged at intervals relative to one another; the gear teeth and the grooves are consistent in shape; in addition, a mounting hole is formed in the middle of the mounting base. The nut mounting head comprises a connecting part and a fixing part, wherein the connecting part and the fixing part are connected together, the fixing part is of a cylindrical structure, a groove is formed in the middle of the fixing part, and the groove is consistent with the nut in shape. The connecting part and the mounting base are consistent in structure; after the connecting part is meshed with the mounting base, the bolt passes through the mounting hole so that the insulating rod and a closed pin mounting head can be fixedly connected. By the adoption of the scheme, a power outage in the process of overhauling the fitting bolt can be avoided, and normal power supply can be guaranteed.
Description
Technical field
The present invention relates to power equipment maintaining field, refer in particular to a kind of metal bolt earth potential nut mounting tool.
Background technology
In equipments of HV transmission lines, bolt is one of modal material, has the several functions such as connection, fixing, load, once bolt goes wrong, directly will affect transmission line equipment general safety level.Charged position metal bolt is mainly divided into two large classes: a class is fastening class bolt, is used for the through-flow junction of all kinds of wire clamps; One class, for connecting class bolt, is used for the connection turning point of all kinds of gold utensil.Main and the nut of this two classes bolt first kind bolt with the use of, nut is connected tight multiplex spring shim as the measure preventing nut from getting loose with screw rod; Equations of The Second Kind bolt mainly uses screw rod as jockey, and the effect of nut prevents screw rod from deviating from, the anti-loose main dependence closed pin of nut itself.
Through field investigation, metal bolt the get loose defect of class in current charged position is mainly Equations of The Second Kind bolt, the nut of this kind of bolt does not need firm effect substantially, the anticreep of itself relies on closed pin, and when closed pin is by External Force Acting disappearance, nut also can get loose very soon, therefore, the present inventor makes further research this, and develop a kind of metal bolt earth potential nut mounting tool, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of metal bolt earth potential nut mounting tool, can when circuit is charged the nut of fitting bolt.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of metal bolt earth potential nut mounting tool, comprise insulating bar, nut mounting head, described insulating bar comprises mount pad, described mount pad is positioned at the front end of insulating bar, and mount pad is disc structure, the circumferential edge of a mount pad wherein plane is provided with apart from one another by the gear teeth and groove, the shape of the described gear teeth is consistent with the shape of groove, and the centre of mount pad offers installing hole; Described nut mounting head comprises the connecting portion and fixed part that link together, and described fixed part is cylindrical structural, and offer groove in the middle of fixed part, the shape of described groove is consistent with nut; Described connecting portion structure is consistent with mount pad, after connecting portion engages with mount pad, then is fixedly connected with closed pin mounting head by insulating bar by installing hole with bolt.
Further, described fixed part outer surface is fixed with spring leaf, offers some through holes under spring leaf, and be provided with the limited post that end is arc in through hole, limited post one end is arranged in groove inner wall, and the other end contacts with spring leaf.
Further, described connecting portion offers U-shaped mounting groove.
After adopting such scheme, the present invention compared with prior art, has the following advantages:
Loosening nut can be tightened under band electro ultrafiltration, avoid having a power failure during maintenance, ensure normal power supply.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in the figure, a kind of metal bolt earth potential nut mounting tool that the present invention discloses, comprise insulating bar 1, nut mounting head 2, the length of insulating bar 1 is greater than the safe distance from alive circuit, described insulating bar 1 comprises mount pad 11, described mount pad 11 is positioned at the front end of insulating bar 1, mount pad 11 is disc structure, the circumferential edge of a mount pad 11 wherein plane is provided with the gear teeth apart from one another by being evenly distributed and groove, the shape of the described gear teeth is consistent with the shape of groove, and the external diameter of the gear teeth is greater than internal diameter, and the centre of mount pad 11 offers installing hole, screw thread is provided with in installing hole.
Described nut mounting head 2 comprises the connecting portion 21 and fixed part 22 that link together, and described fixed part 22 is cylindrical structural, and offer groove in the middle of fixed part 22, nut can be inlayed in a groove; Fixed part 22 outer surface is fixed with spring leaf 23, the length of spring leaf 23 is greater than 1/2 of fixed part 22 outer ring circumference, spring leaf offers some through holes 23 times, be provided with the limited post 24 that end is arc in through hole, limited post 24 one end is arranged in groove inner wall, and the other end contacts with spring leaf 23, when nut is mounted to after in groove, limited post 24 suffers oppression outwards motion, but has spring leaf 23, so nut can be subject to the reaction force of limited post 24 and be fixed due to external stability.
Described connecting portion 21 structure is consistent with mount pad 11, and connecting portion 21 can engage with mount pad 11, just can not lateral rotation again after the gear teeth and groove intermesh, and is then fixedly connected with nut mounting head 2 by insulating bar 1 by installing hole with screwing bolts.Conveniently install, the installing hole of connecting portion 21 is replaced by U-shaped mounting groove.
During use, entangle nut by bolt mounting head, nut can be tightened.
Above are only specific embodiments of the invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
