Description
Technical field
The fixture of the ground clamp of using when the utility model relates to a kind of power construction, particularly a kind of ground clamp.
Background technology
During the transmission line interruption maintenance; Because of static, induced electricity, instead send misoperations such as electricity or abnormal unexpected incoming call; In transmission line, can produce dangerous voltage and electric arc, 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; Will on transmission line, articulate temporary ground wire, the instrument of temporary ground wire has elements such as ground clamp, ground wire stake and earth connection.Ground clamp is used for being clamped in tightly the electric wire of transmission line; The ground wire stake is used to insert and undergroundly contacts well with ground; Earth connection is used to connect ground clamp and ground wire stake; During the transmission line interruption maintenance on transmission line temporary ground wire be safety measure indispensable in the electric power maintenance work, only after hanging up properly earth connection on the dead line, can carry out the upkeep operation of contact wire.In the instrument of interim hanging earthing conductor, ground clamp is most important element on dead line.In the prior art, ground wire accompanies the hook-type ground clamp, and the hook-type ground wire accompanies hooked ground wire clamp; The ground wire clamp has straight-arm; The lateral wall of straight-arm has the ground wire contact, and the upper end of straight-arm is connected with the crotch that Open Side Down, and there is the neck of hook that can link to each other with action bars the lower end of ground wire clamp; Flexible sheet metal electric wire folder is connected with lead between electric wire folder and the ground wire contact in the crotch of ground wire clamp.
During temporary ground wire, good ground wire stake is inserted in hook taking shape ground clamp, earth connection and ground wire stake on the ground on transmission line; Between hook-type ground clamp and ground wire stake, connect earth connection, be connected in the hook-type ground clamp on the action bars, lift action bars; Hang over the mouth of hook of hook-type ground clamp on the tower-mounted electric wire of transmission line electricity; Pulling hook-type ground clamp lets the interior elastic sheet metal electric wire folder of the mouth of hook clamp electric wire downwards, and the realization ground clamp is connected with the transmission line electric wire.This hook-type ground clamp dismounting inconvenience, ground clamp contacts defective tightness with electric wire, and in the big environment of wind, lead shake ground clamp also splits away off from transmission line easily and causes security incident.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, to propose a kind of easy accessibility, and ground clamp contacts closely with electric wire, does not allow caducous screw rod compression type angle ground clamp.
The utility model is realized with following method.
Screw rod compression type angle ground wire accompanies hooked ground wire clamp, and the ground wire clamp has straight-arm, and the lateral wall of straight-arm has the ground wire contact; The upper end of straight-arm is connected with the crotch that Open Side Down, and the mouth of hook of crotch is a semicircular arc, and there is angle the outer end of crotch; Have in the straight-arm upper and lower to slideway; Slide block is arranged in the slideway, and slide block stretches out the semi arch piece that slideway partly has the opening that matches with the downward semi arch mouth of hook of straight-arm open upper end to make progress, and there is the angle that matches with the angle of crotch outer end the outer end of semi arch piece; Slide block part in slideway has internal thread hole; The rotation of the lower end of straight-arm is hinged with screw rod, and screw rod stretches out a section of straight-arm lower end has the neck of hook that can link to each other with action bars, and screw rod a section in straight-arm is spun on slide block in slideway in partly the internal thread hole.
During use, rotate the screw rod of the utility model earlier, driving sliding block descends; Let the downward semi arch mouth of hook of straight-arm open upper end and slide block stretch out distance between the slideway part semi arch slide block greater than the external diameter of transmission line circle electric wire; Be connected in the neck of hook of the utility model on the action bars, lift action bars, hang over the downward semi arch mouth of hook of straight-arm open upper end on the tower-mounted round electric wire of transmission line electricity; The rotary manipulation bar drives screw rod and rotates; Screw rod rotates and can driving sliding block rise, and the semi arch mouth of hook and the slide block downward with the straight-arm open upper end stretch out slideway part semi arch slide block circle electric wire clamped, and the realization ground clamp is connected with the transmission line electric wire.
In the utility model straight-arm slideway is arranged, the semi arch slide block that matches with the semi arch mouth of hook is arranged in the slideway, but the screw rod that has driving sliding block to slide in the straight-arm, and screw rod stretches out a section of straight-arm lower end has the neck of hook that can link to each other with action bars.During use, the available action bar drives the semi arch mouth of hook and the semi arch slide block clamps electric wire, and the utility model easy accessibility, contacts closely with electric wire, is not easy to come off behind the clamping electric wire when the clamping electric wire.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
