During the transmission line interruption maintenance, because of static, induced electricity, instead send the misoperations such as electricity or abnormal unexpected incoming call, can produce dangerous voltage and electric arc in transmission line, this dangerous voltage and electric arc are known from experience the generation injury to the operation electrician people of contact power transmission circuit on transmission line.In order to prevent that above-mentioned dangerous voltage and electric arc from producing injury to the operation electrician human body of contact power transmission circuit on transmission line, press the power construction regulation, when the transmission line interruption maintenance, articulate temporary ground wire at transmission line, the instrument of temporary ground wire has the elements such as earth connection, earth wire pile and electric wire.Earth connection is used for being connected to tightly the electric wire of transmission line, earth wire pile is used for inserting and undergroundly contacts well with ground, electric wire is used for connecting earth connection and earth wire pile, during the transmission line interruption maintenance on transmission line temporary ground wire be safety measure indispensable in the power equipment maintaining work, only after dead line hangs up properly earth connection, can carry out the upkeep operation of contact wire.In the instrument of interim hanging earthing conductor, earth connection is most important element on dead line.In the prior art, earth connection has the coupling type earth connection, the coupling type earth connection has the ground wire clamp, the ground wire clamp has straight-arm, the upper end of straight-arm is connected with the crotch that Open Side Down, flexible sheet metal electrical wire clip in the crotch, the lateral wall of straight-arm has the ground wire contact, and the lower end of ground wire clamp is connected with the tubular action bars of insulating material.
On transmission line during temporary ground wire, getting hook-type earth connection, electric wire and earth wire pile, be plugged on the ground earth wire pile, between coupling type earth connection and earth wire pile, connect earth connection, lift action bars, the mouth of hook of coupling type earth connection is hung on the electric wire of transmission line, spur the coupling type earth connection downwards, allow elastic sheet metal electrical wire clip in the mouth of hook the wire clamping of transmission line, realize the electric wire ground connection of transmission line.The electric wire clamping contact defective tightness of this coupling type earth connection and transmission line, sometimes because wind or people bump, the electric wire shake that causes splits away off easily the coupling type earth connection and causes security incident from the electric wire of transmission line.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind of coupling type earth connection with fore shaft of splitting away off from the electric wire of transmission line of being not easy.
The present invention is achieved using the following method.
Coupling type earth connection with fore shaft has the ground wire clamp, the ground wire clamp has straight-arm, the upper end of straight-arm is connected with the crotch that Open Side Down, flexible sheet metal electrical wire clip in the crotch, the lateral wall of straight-arm has the ground wire contact, the lower end of ground wire clamp is connected with the tubular action bars of insulating material, there is the rectangular through-hole vertical with straight-arm the ground wire contact top of straight-arm, be installed with the active plugboard vertical with straight-arm in the through hole, the above and below of action bars circumference has respectively along the strip hole of action bars axis direction, the inwall of action bars, between the top of the below of upper strip hole and lower hole strip hole interior circumferential band is arranged, in the action bars, the insulating material drive link that passes interior circumferential band is arranged, drive link is connected with radial loop below interior circumferential band, the lower end of drive link is hinged with an end of drive rod under the arc that stretches out lower strip hole, the upper end of drive link is hinged with an end of drive rod on the arc that stretches out strip hole, the top of strip hole is connected with outer circular boop under the action bars excircle, be hinged with an end of handle on the circular boop, the other end of handle is hinged on the other end of lower drive rod, the end of active plugboard outside the crotch of ground wire clamp is hinged on the other end of drive rod, in the action bars pipe, the spring that makes drive link be subject to downward force is arranged between the interior circumferential band of the radial loop of drive link and action bars inwall.
In the pipe of the present invention, between drive link and the insulating bar spring that makes drive link be subject to downward force is arranged, in common nature, because of the elastic force of spring, active plugboard is on the mouth of hook of gear at crotch in the side in the ground wire clamp crotch.
During use, operating personnel's hand-held bar, press handle, compressed lower at spring, by lower drive rod, drive link and upper drive rod drive active plugboard and slide to the outside of ground wire clamp crotch, make the side of active plugboard in ground wire clamp crotch leave the mouth of hook of crotch, the mouth of hook of coupling type earth connection is hung on the electric wire of transmission line, spur the coupling type earth connection downwards, allow elastic sheet metal electrical wire clip in the mouth of hook the wire clamping of transmission line, release handle then, spring is removed compression, by lower drive rod, drive link and upper drive rod drive active plugboard to the inner slide of ground wire clamp crotch, and gear is on the mouth of hook of crotch.
There is the rectangular through-hole vertical with straight-arm the ground wire contact top of ground wire clamp straight-arm of the present invention, be installed with the active plugboard vertical with straight-arm in the through hole, active plugboard is connected with the drive unit that is comprised of handle, lower drive rod, drive link, upper drive rod and spring, control crank, also can make active plugboard leave the mouth of hook clamping electric wire of crotch, can make the active plugboard gear on the mouth of hook of crotch, prevent from because wind or people bump the electric wire shake that causes the coupling type earth connection being split away off from the electric wire of transmission line.
