Problems solved by technology
Most of the high-voltage transmission lines use overhead bare wires. If an out-of-control kite is placed on two high-voltage lines, in cloudy and rainy days, the damp kite line will cause a short circuit, and the automatic power protection facility will trip, causing economic losses and affecting normal operation of power lines
For this reason, it is necessary to remove the out-of-control kite entangled on the high-voltage transmission line in time. In order to eliminate the hidden danger of the kite entangled on the transmission line, an insulating ladder is generally used to perform equipotential operation without power failure. The insulating ladder currently used in the field is a frame Type structure, and can not be moved, inconvenient to operate

The invention discloses a centipede-type ladder for eliminating foreign maters on a conducting wire under an electrification condition. In a ladder body of a main ladder (2), a straight rod (6) is used as a central main cone; footstools (7) are arranged on the ladder body straight rod (6) and are alternately arranged and fixed on the two sides of the straight rod (6); a hanger (3) is fixedly arranged at the top end of the ladder body straight rod (6) of the main ladder (2); a movable pulley (4) is arranged in the hanger through a bolt (5); a bottom ladder (1) is connected to the lower end of the ladder body straight rod (6) of the main ladder (2) through a hinge in a movable manner; and the ladder body straight rod (6) of the bottom ladder (1) is connected with the footstools (7). Electric power circuit maintenance personnel eliminates the foreign matters on the conducting wire by using the centipede-type ladder under the electrification condition, and the pulley (4) can move on the conducting wire, so that the foreign matters at different positions of the conducting wire are convenient to eliminate; and the ladder is convenient to carry, mount and detach.
Description
technical field [0001] The invention relates to an operation tool for maintenance and maintenance of transmission lines in the power supply industry, in particular to an insulating ladder used for removing foreign objects in the wires of high-voltage transmission lines when charged. Background technique [0002] Every spring and autumn, more and more people fly kites in the wild. Most of the high-voltage transmission lines use overhead bare wires. If an out-of-control kite is placed on two high-voltage lines, in cloudy and rainy days, the damp kite line will cause a short circuit, and the automatic power protection facility will trip, causing economic losses and affecting normal operation of power lines. For this reason, it is necessary to remove the out-of-control kite entangled on the high-voltage transmission line in time. In order to eliminate the hidden danger of the kite entangled on the transmission line, an insulating ladder is generally used to perform equipotentia...
