Abstract
Description
Technical field
The utility model relates to a kind of grounding wire device for power transmission lines overhauling, belongs to electric power overhaul protection technical field of tools.
Background technology
Power system transmission line breaks down, and needs interruption maintenance.The important safeguard measure of interruption maintenance is installing earth connection, to guarantee that maintainer exempts from the injury of getting an electric shock in maintenance process.Existing earth connection normally adopts the wire clamp folder being connected with ground to hang on the line conductor having a power failure.Insecure due to contacting between wire clamp and line conductor, be subject to the factors such as wind-force and disturb to cause and come off, the cross bar on extra high voltage line shaft tower and the vertical range between line conductor are longer in addition, cause wire clamp installing, tear folder difficulty open.
Utility model content
The purpose of this utility model is to provide a kind of installing, it is convenient to remove, the grounding wire device for power transmission lines overhauling of good anti-drop effect.
Its technical scheme is: a kind of grounding wire device for power transmission lines overhauling, comprise ground connection hook and be connected to the grounding clamp on ground connection hook by wire, it is characterized in that: described ground connection hook is top straight portion and bottom crotch two parts by plate bending, be approximate " C " type structure, between ground connection hook top straight portion and crotch part, be provided with clamping plate, place, clamping plate middle position is connected with pull bar, the tie rod hole that pull bar upper end is offered through ground connection hook top straight portion, by stay cord ring, be connected with stay cord, on the clamping plate on pull bar both sides, be connected with respectively bolt, the screw that the upper end of bolt is offered through ground connection hook top straight portion, by nut, fixed, on bolt between clamping plate and ground connection hook top straight portion, be set with spring, position placed in the middle, clamping plate front side is connected with hook, and position placed in the middle, straight portion front side, ground connection hook top offers and links up with the draw-in groove coordinating, on pull bar between clamping plate and ground connection hook top straight portion, be embedded with and buckle.
Its technique effect is: this device utilizes and to be sleeved on the clamping plate that the Diastolic Force of bolt upper spring between clamping plate and ground connection hook top straight portion is connected with manual draw bar, can control easily the clamping plate that partly coordinate with ground connection hook crotch, realization is to the parcel clamping of line conductor or loosen disengaging, there is installation, dismounting easily, ground connection hook contacts with line conductor firmly, anticreep is good, uses the features such as flexibility is strong, while being applicable to the transmission line interruption maintenance operation of 110kV and above, uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Embodiment
As Figure 1-3, a kind of grounding wire device for power transmission lines overhauling, comprises ground connection hook 3 and is connected to the grounding clamp 34 on ground connection hook by wire 33.Described ground connection hook 3 is top straight portion and bottom crotch two parts by plate bending, is approximate " C " type structure.Between ground connection hook top straight portion 31 and crotch part, be provided with clamping plate 7, place, clamping plate middle position is connected with pull bar 1, the tie rod hole that pull bar upper end is offered through ground connection hook top straight portion, by stay cord ring, be connected with insulation stay cord 8, on the clamping plate on pull bar both sides, be connected with respectively bolt 2, the screw that the upper end of bolt is offered through ground connection hook top straight portion, is fixed by nut.On bolt between clamping plate and ground connection hook top straight portion, be set with spring 5.Position placed in the middle, clamping plate front side is connected with hook 6, and position placed in the middle, straight portion front side, ground connection hook top offers and links up with the draw-in groove 32 coordinating; On pull bar between clamping plate and ground connection hook top straight portion, be embedded with and buckle 4.
During use, utilize insulation stay cord 8 to pull pull bar 1, make draw-in groove 32 interlocks in hook 6 on clamping plate 7 and ground connection hook top straight portion, grounding clamp 34 is fixed on shaft tower tower material; Then transfer insulation stay cord, make the crotch part of ground connection hook 3 hook wire from line conductor below, tension insulation stay cord drives pull bar to rise gently, make the hook on clamping plate depart from the draw-in groove in the straight portion of ground connection hook top, be sleeved on the spring 5 on the bolt 2 between ground connection hook top straight portion and clamping plate, under the effect of Diastolic Force, suppress rapidly clamping plate and press down, thereby line conductor parcel is clamped between clamping plate and the crotch part of ground connection hook, realizes anticreep object; Operation is complete, pull pull bar make to buckle 4 risings through tie rod hole after, loosening pull bar makes to buckle on the upper surface that automatic clamping is connected on ground connection hook top straight portion, thereby clamping plate are loosened and depart from line conductor, ground connection hook crotch part is under the effect of gravity, depart from line conductor, can complete dismounting earth connection.
