Abstract

The invention discloses a winding drum underslung type ground wire which comprises a duckbilled impact type wire clamp and an insulation rope. A barb type hung slide way is connected with an outer surface which is higher than the position from a clamp front end to a clamp handle tail portion along the longitudinal center line of one clamp piece of the duckbilled impact type wire clamp, one end of the insulation rope is hung on the slide way in a sleeving mode, the other end of the insulation rope is fixed on a casing of a ground wire twisting and releasing box, a multi-strand annealed copper wire is wound on a rotation shaft in the ground wire twisting and releasing box, the outer end of the annealed copper wire is connected with the tail end of the other clamp piece of the wire clamp, a crank is installed at one end on the outer side of the rotation shaft in the ground wire twisting and releasing box, and a ground terminal fixing clip is installed at the outer end of the rotation shaft on the other side of the ground wire twisting and releasing box. During installation of the ground wire, the fixing clip is firstly installed on a cross arm, then a wire clamp port is upwards placed, and the insulation rope is pulled to hang the ground wire on a guide line, so that the ground wire is convenient to operate and time-saving.

Description

Reel reversely hung Yong earth connection
Technical field:
The present invention be a kind of for power failure operation hang, the reel reversely hung Yong earth connection of handled easily when tearing transmission line phase-splitting earth connection open.
Background technology:
According to the power industry relevant regulations, the method of tearing hanging earthing conductor open that electric power line pole tower is present is, earth connection generally is suspended on the terminal tower bow line at transmission line two ends during power failure, current use be the impacting type earthing wire clip, operating personnel at first are fixed on the earth terminal of connecting wires on the cross-arm, then utilize insulating cord that a kind of duckbilled impacting type wire clamp is contained on the wire, namely finished the installation of earth connection.But when running into large corner pole, interior angle bow line and cross-arm horizontal range are during greater than 1.5m, operating personnel are difficult to exactly duckbilled impacting type wire clamp is installed on the wire, when straight line pole hangs, since earth connection length more than 3m and wire clamp lightweight, during installation, multiple impact also is difficult to it is clipped on the wire.
Summary of the invention:
The purpose of this invention is to provide a kind of easy to operate, reel reversely hung Yong earth connection of saving the set-up time.
Technical scheme of the present invention is finished as follows, reel reversely hung Yong earth connection, it comprises a duckbilled impacting type wire clamp and an insulating cord, it is characterized in that: on an intermediate plate longitudinal centre line of earthing clamp, exceed outer surface from chuck front end to clamp holder afterbody and be connected with a barb-type suspension slideway, one end cover of insulating cord hangs on the slideway, the other end of insulating cord is fixed on the shell of an earth connection Storage case, rotation axis is wound with a multiply annealed copper wire in Storage case, the outer end of annealed copper wire is connected to another intermediate plate tail end of wire clamp, one end is equipped with a crank in the outside of Storage case rotation axis, in the opposite side rotation axis outer end of Storage case an earth terminal fixed card is installed.
The present invention is installed in fixed card on the cross-arm first when mounted, the wire clamp mouth is placed up again, and the pulling insulating cord just can hang over it on wire, and is easy to operate, save time.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, the present invention exceeds outer surface from chuck front end to the clamp holder afterbody of longitudinal centre line to be connected with a barb-type and to hang slideway 2 on an intermediate plate of a duckbilled impacting type wire clamp 1, one end cover of insulating cord 4 hangs on the slideway, the other end of insulating cord is fixed on the shell of an earth connection Storage case 5, rotation axis is wound with a multiply annealed copper wire 7 in Storage case, the outer end of annealed copper wire is connected to another intermediate plate tail end of wire clamp, one end is equipped with a crank 6 in the outside of Storage case rotation axis, in the opposite side rotation axis outer end of Storage case an earth terminal fixed card 3 is installed.During installation, first the ground connection fixed card is installed on the cross-arm, then utilizes insulating cord and barb-type to hang slideway by operating personnel and wire clamp is adjusted to jaws up, spur again insulating cord, just wire clamp can be hung on the wire easily.
