Abstract
The invention discloses a ground wire device used for power transmission line maintenance. The ground wire device comprises a grounding hook and a grounding card connected to the grounding hook through a guide line. The grounding hook is composed of a top end straight part and a lower hook part. The top end straight part and the lower hook part are formed by bending a plate bock.. The grounding hook is of a similarly C-shaped structure. A clamp plate is arranged between the top end straight part and the hook part. A pull rod is fixedly connected with the cental position of the clamp plate. The top end of the pull rod penetrates through a pull rod hole formed in the top end straight part of the grounding hook and is connected with the pull rope through a pull rope ring. Parts, on the two sides of the pull rod, of the clamp plate are respectively connected with bolts. Upper ends of the bolts penetrate through screw holes formed in the top end straight part of the grounding hook and are fixed through nuts. The bolts between the clamp plate and the top end straight part of the grounding hook are sleeved with springs. A hook is connected with the central position on the front side of the clamp plate. A clamping groove matched with the hook is formed in the central position of the front side of the top end straight part of the grounding hook. A hanging buckle is embedded in the pull rod between the clamp plate and the top end straight part of the grounding hook. The ground wire device has the advantages of being good in coming-off preventing performance, strong in utilization flexibility and and like.
Description
Technical field
The present invention relates to a kind of grounding wire device for power transmission lines overhauling, belong 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 the installing earth connection, to guarantee the maintainer, exempts from the injury of getting an electric shock in maintenance process.Existing earth connection normally adopts the wire clamp folder be connected with ground to hang on the line conductor had a power failure.Insecure due to contacting between wire clamp and line conductor, be subject to the factor such as wind-force and disturb to cause and come off, the cross bar on the extra high voltage line shaft tower and the vertical range between line conductor are longer in addition, cause the wire clamp installing, tear the folder difficulty open.
Summary of the invention
The object of the present invention is to provide a kind of installing, remove convenient, 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 the ground connection hook and be connected to the grounding clamp on the ground connection hook by wire, it is characterized in that: described ground connection hook is top straight portion and bottom crotch two parts by the plate bending, be approximate " C " type structure, be provided with clamping plate between ground connection hook top straight portion and crotch part, place, clamping plate middle position is connected with pull bar, the tie rod hole that the pull bar upper end is offered through ground connection hook top straight portion, by the stay cord ring, with stay cord, be connected, be connected with respectively bolt on the clamping plate on pull bar both sides, the screw that the upper end of bolt is offered through ground connection hook top straight portion, by nut, fixed, be set with spring on bolt between clamping plate and ground connection hook top straight portion, 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 coordinated, be embedded with and buckle on pull bar between clamping plate and ground connection hook top straight portion.
Its technique effect is: the clamping plate that this device utilizes the Diastolic Force be sleeved on bolt upper spring between clamping plate and ground connection hook top straight portion to be connected with manual draw bar, can control easily the clamping plate that partly coordinate with ground connection hook crotch, realization clamps the parcel of line conductor or loosens disengaging, there is installation, dismounting easily, the ground connection hook contacts with line conductor firmly, anticreep is good, uses the characteristics such as flexibility is strong, while being applicable to the transmission line interruption maintenance operation of 110kV and above, uses.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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, comprise ground connection hook 3 and be connected to the grounding clamp 34 on the ground connection hook by wire 33.Described ground connection hook 3 is top straight portion and bottom crotch two parts by the plate bending, is approximate " C " type structure.Be provided with clamping plate 7 between ground connection hook top straight portion 31 and crotch part, place, clamping plate middle position is connected with pull bar 1, the tie rod hole that the pull bar upper end is offered through ground connection hook top straight portion, by the stay cord ring, with insulation stay cord 8, be connected, be connected with respectively bolt 2 on the clamping plate on pull bar both sides, the screw that the upper end of bolt is offered through ground connection hook top straight portion, fixed by nut.Be set with spring 5 on bolt between clamping plate and ground connection hook top straight portion.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 coordinated; Be embedded with and buckle 4 on pull bar between clamping plate and ground connection hook top straight portion.
During use, utilize insulation stay cord 8 to pull pull bar 1, make draw-in groove 32 interlocks on 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 the insulation stay cord, make the crotch part of ground connection hook 3 hook wire from the line conductor below, tension insulation stay cord drives the pull bar rising gently, make the hook on clamping plate break away from the draw-in groove on 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 the line conductor parcel is clamped between the crotch part of clamping plate and ground connection hook, realizes the anticreep purpose; 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 break away from line conductor, ground connection hook crotch part is under the effect of gravity, break away from line conductor, can complete the dismounting earth connection.
