Description
Technical field
The square bus ground clamp of using when the utility model relates to a kind of power construction, particularly a kind of fixture of side's bus 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 the square bus of 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 square bus of transmission line; Downward pulling hook-type ground clamp lets the interior elastic sheet metal electric wire folder of the mouth of hook clamp square bus, 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 square bus, and square bus is at horizontal level, and the hook-type ground clamp is the side's of grasping bus effectively; When square bus is tilting or during vertical position, 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 the caducous straight folder formula screw rod side of compressing bus ground clamp.
The utility model is realized with following method.
The straight folder formula screw rod side of compressing bus ground wire accompanies the ground clamp body, 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 of lateral openings, and the mouth of hook of crotch is a rectangle, and the lower end of crotch is hinged with centering block; Have on the centering block and the relative rectangular recess of the oblique arm upper lateral rectangle mouth of hook, have in the straight-arm upper and lower to slideway, slide block is arranged in the slideway; Be hinged with connecting rod between slide block and the centering block, slide block part in slideway has internal thread hole, and the lower end rotation of straight-arm is hinged with screw rod; 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 in the internal thread hole of slide block part in slideway.
The screw rod of rotation the utility model drives the centering block swing, can make the rectangular recess merging on the straight-arm upper lateral rectangle mouth of hook and the centering block or separates, and the rectangular apertures of merging matches with the size and dimension of square bus.
During use, the screw rod of rotation the utility model drives centering block and outwards puts earlier; Let the straight-arm upper lateral rectangle mouth of hook and the open distance of centering block thickness greater than transmission line side's bus; Be connected in the neck of hook of the utility model on the action bars, lift action bars, be against the straight-arm upper lateral rectangle mouth of hook on the square bus of transmission line; The rotary manipulation bar drives screw rod and rotates; Screw rod rotates and can drive centering block and inwardly put, and square bus clamped, the realization ground clamp is connected with transmission line side's bus with the side direction rectangle mouth of hook of straight-arm upper end and the rectangular recess on the centering block.
In the utility model straight-arm slideway is arranged, slide block 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 centering block swing and is held in square bus clip between the side direction rectangle mouth of hook and the rectangular recess on the centering block on the oblique arm.The utility model is in clamping side during bus, easy accessibility, contacts closely with square bus line, is not easy to come off behind clamping side's bus.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
