Description

A kind of cement rod-type power transmission line overhead ground wire auxiliary device
Technical field
The invention belongs to electrical equipment technical field, especially a kind of cement rod-type power transmission line overhead ground wire auxiliary dress It sets.
Background technology
Aerial earth wire is one of effective reduction lightning outage rate device, but due to by the influence of topography, setting up or tearing open When except aerial earth wire operation, the higher straight line pole of topographical position is encountered(Tower)When, since hitch point is higher, in same span internal frame Vacant lot shape dead weight and stress load reach maximum, can not only be promoted aerial earth wire to the predetermined height of hitch point with staff's strength Degree influences attachment installation or removes.Based on this difficult point, the main two kinds of options of traditional processing mode:
When manpower pickaback mode, second is that wooden interim pole mode.Because steel strand wires dead weight and stress load are larger, exceed manpower Range and the fracture of wooden pole in one's power, are easy to damage the positions such as personnel's waist, shoulder in both ways, how set Count it is a kind of convenient for fast lifting ground wire device be pump field technology personnel's long felt direction.
The patent document of Authorization Notice No. CN206814366U discloses a kind of transmission line concrete rod earth wire band iron promotion Tool, including holder, crowbar and crowbar load component, the holder include bolt of long stem, round steel and bottom plate, and the one of the round steel End be welded on the bottom plate, the other end is connect with one end of the bolt of long stem, the other end of the bolt of long stem with it is described Crowbar load component connects, and the bolt of long stem is provided with nut, the crowbar load component and institute with the round steel junction Crowbar connection is stated, the round steel uses 45# steel, the round steel to be internally provided with internal thread, the size of internal thread and the stock External screw thread on bolt matches, and the bolt of long stem is connected with the round steel by external screw thread and internal thread, the crowbar For adjustable in length formula crowbar, the crowbar handgrip part is provided with Anti-slip cover, is set with the crowbar load component contact position It is calculated as that there is one fixed width and the U-shaped framework of thickness.The structure is only applicable to ground or high-altitude, and closely ground wire promotes work Industry, without fundamentally solving the problems, such as that ground wire is promoted.
The patent document of application publication number CN107887836A discloses a kind of tangent tower overhead-groundwire lifter, including horizontal torsion The combination of brilliance iron, pressing plate, cross-bridges iron, cross-bridges level lengthen iron, adjustable lead screw;Horizontal angle bar combination of turning one's head is located at aerial earth wire hanging wire Point top is simultaneously fixed with tangent tower, and pressing plate is fixed on horizontal angle bar group of turning one's head and closes, a pair of of angle bar of angle bar combination, each angle One angle bar of iron is facing away under, and another angle bar back of the body of two angle bar is drawn close in opposite directions, and the pressing plate is ladder-like, and ladder vertical plane adapts to In the height setting of the angle bar directed downwardly back of the body, upper ladder plane of structure is fixed on the angle bar back directed downwardly of angle bar, and downstairs plane of structure is fixed On the cross-bridges iron, so that cross-bridges iron is passed through with tangent tower and tighten pressing plate fixation.The structure is disadvantageous in that:Horizontal torsion Brilliance iron combine with it is complex in the fixed form of tangent tower, two cross-bridges levels on cross-bridges iron lengthening iron is using process In stability it is not strong, in addition, due to cross-bridges level lengthen iron specific mounting means, the aerial baseline being disposed below Hoisting depth is limited, and manpower auxiliary is needed to carry out the installment work of the slightly above end of connecting wires of fixed point.
