Problems solved by technology

Usually, we use insulating operating rods of corresponding voltage levels (installed in front with matching two-tooth crawlers, three-tooth climbers or semicircle hooks) to remove foreign objects. When cleaning foreign matter, it is easily affected by the wind force, which makes it impossible to accurately grasp foreign matter, and the two-toothed claw does not have the function of cutting foreign matter, resulting in inconvenient operation and low work efficiency when removing foreign matter

Abstract

The invention discloses a special tool for removing foreign matters on power transmission line conductors. The special tool is characterized in that the special tool is formed by an insulating rod, a clamping mechanism, a cutting mechanism, a turning mechanism and a transmission mechanism. The clamping mechanism comprises a clamp body, a clamp mouth, a movable clamp mouth and torsion spring. The cutting mechanism comprises a guide tube, a blade guide block, a blade, a blade guard pin and a spring. The turning mechanism is a bidirectional steering knuckle. The transmission mechanism comprises a knife handle frame, a clamp mouth handle, a blade handle, an insulation tiepiece, a blade tiepiece and a clamp mouth tiepiece. The special tool has the advantages: 1) the special tool can carry out multi-angle adjustment to adapt to different conditions; 2) the special tool has good removing effect on both light foreign matters and heavy foreign matters; 3) the special tool can realize live grounding wire foreign matter removing without causing interference and influence on operation equipment in the removing process; and 4) the special tool, made of high-strength alloy steel, is not easy to damage, compact in overall structure, small in size and light and portable.

Description

technical field [0001] The patent of the present invention relates to a tool for power transmission equipment, in particular to a special tool for removing foreign objects in power transmission line wires with simple operation, safe use and high work efficiency. Background technique [0002] With the rapid development of the power grid and the continuous improvement of users' requirements for the reliability of power supply, higher requirements are put forward for the safety and reliability of power grid operation. Safe operation of the power grid, and even cause line tripping accidents. [0003] During the operation of the transmission line, under the influence of the external environment, foreign objects such as plastic films, ribbons, balloons, etc. are often hung on the line conductor, which seriously endangers the safe and reliable operation of the line. Usually, we use the insulating lever of the corresponding voltage level (the supporting two-tooth climbing, three-to...
