Abstract
The utility model relates to an operating rod for a grounding wire. The operating rod comprises a conductive clamp and an insulating rod, wherein the conductive clamp consists of a fixed clamp and a movable clamp which are both made of metal; an insulating pull rod penetrating two ends of the insulating rod is arranged in the insulating rod; the movable clamp is fixed at the upper end of the insulating pull rod; the lower part of the fixed clamp is fixed at the upper end of the insulating rod, and the upper part of the fixed clamp extends above the upper end surface of the movable clamp to form a hook; a spring seat is arranged at the lower part of the fixed clamp; a compression spring is mounted on the pull rod between the lower end of the movable clamp and the spring seat; and the compression spring tightly presses the upper end surface of the movable clamp onto the hook of the fixed clamp under the action of no external force. As the movable clamp clamps a lead wire on the fixed clamp from the bottom up, the clamping force is large, the lead wire is firmly fixed in the clamp, the safety performance is good and the operation is convenient.
Description
Technical field
The utility model relates to a kind of supply line repair apparatus, specifically a kind of earth connection action bars.
Background technology
At hotline maintenance such as electric power system, transmission line with when safeguarding, often need to use the earth connection action bars, with lead ground connection.This earth connection action bars is made up of conductive chuck and insulating bar usually, and earth connection is fixed on the chuck, during operation, clamps on the skyborne lead of suspension with chuck, and lead is electrically connected with earth connection.The disclosed a kind of earth connection action bars that comes to this of Chinese patent CN2632878Y, because wire clamp is between the tongue piece of both sides, its chucking power depends on the elastic force of the elastic pressuring plate of tongue piece lower end.If elastic force is excessive, then lead is difficult to get between the tongue piece, if elastic force is too small or inefficacy, easy meeting causes between lead and the chuck loosening, entail dangers to system safety operation and personal safety.
Summary of the invention
The purpose of the utility model provides a kind of earth connection action bars, and lead can be clamped on the chuck easily, and clamping is more firm, can not become flexible, and security performance is good.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: comprise conductive chuck and insulating bar; Conductive chuck is made up of the geometrical clamp and the live splint of metal material, and insulating bar is the pipe fitting of hollow, is provided with the insulated tension pole at perforation insulating bar two ends in the insulating bar; Live splint is fixed on the insulated tension pole upper end, and the live splint upper end is useful on the upper surface of clamping lead; The geometrical clamp bottom is fixed on the insulating bar upper end, the oriented hook that extends to top, live splint upper surface in its top, and there is the lower surface of clamping lead the hook lower end; The geometrical clamp bottom is provided with spring base, and the compression spring is housed on the pull bar between live splint lower end and the spring base, the live splint upper surface is held out against on geometrical clamp hook lower surface at no external force effect lower compression spring.
During use; Only need to stretched insulated tension pole; Gap between geometrical clamp and the live splint forms wiring inlet; To hang skyborne lead and put into, unclamp insulated tension pole again, and under the effect of compression spring, be about to wire clamp on the live splint upper surface be held on the geometrical clamp lower draw-bar end face by this porch.Lead can be got in the chuck by a side non-resistance ground, and the elastic force of compression spring is difficult for losing efficacy greatly and than shell fragment, thereby more firm to the lead clamping, and security performance is good.
Lead gets into the chuck porch for ease, and insulating bar is provided with the locking device that insulated tension pole is moved down locking position behind the segment distance.A kind of preferred structure of said locking device is: be made up of lock pin and spring, have the radial hole of mounting spring and lock pin on the insulated tension pole sidewall, have the pin-and-hole with the lock pin coupling on the sidewall of insulating bar.When insulated tension pole is descending when making the pin-and-hole position of lock pin to insulating bar; Spring pushes lock pin in the pin-and-hole, can insulated tension pole be fixed on the insulating bar, lead is placed on by the porch of chuck puts into chuck again; Press lock pin insulated tension pole is upwards discharged, lead is clamped.
For conveniently pushing above-mentioned lock pin, the button of unlatching-locking apparatus is housed on the said insulating bar, be hinged on insulating bar by support in the middle of the button, an end extends to the pin-and-hole outside, between the other end and the insulating bar back-moving spring is housed.
To the stretched insulating bar, the utility model is provided with draw ring in the insulated tension pole lower end for convenient.
For prevent that lead from sliding on chuck, geometrical clamp hook lower surface is provided with the groove to the lead location.
Can be known that by technique scheme the utility model live splint from bottom to top is held in wire clamp on the geometrical clamp, chucking power is big, and lead is firm at the chuck internal fixation, can not become flexible, and security performance is good, and lead passes in and out by a side non-resistance, and is easy to operate.
