Problems solved by technology
This kind of tool for replacing double-string insulators has a large volume and many separate parts, which not only increases the difficulty of handling the tool, but also adds two separate processes during the replacement: connecting the U-shaped ring to the double-string insulator The process of connecting the plate holes and the process of hanging the double hooks of the pull rods on the double U-shaped rings make the replacement operation complicated and difficult, and it is difficult to ensure construction safety

Abstract
The invention discloses a changer of double-string insulator strings capable of stretching in two directions. A left screw and a right screw with forward and reverse threads are respectively connected to two ends of a connection link through inner threads; a left puller and a right puller connected with holes on a connecting plate of a fixed insulator string are respectively arranged at the outer ends of the left screw and the right screw; two annular sleeves at the front part of a rocking handle are sleeved on a connection link at a gap; two-way ratchet wheels fixed on the connection link are arranged between the two annular sleeves at a certain gap, and two-way pawls acting together with the two-way ratchet wheels are hinged between the two annular sleeves. The changer of the double-string insulator strings is suitable for changing the insulator strings on an electric transmission line. A detachable structure is adopted, and the changer of the double-string insulator strings has the characteristics of being convenient to carry, high in work efficiency, and safe and reliable to operate.
Description
technical field [0001] The invention relates to a tool for replacing insulator strings under power transmission line operation, in particular to a double-string insulator replacement tool capable of bidirectional expansion and contraction. Background technique [0002] At present, the replacement of double-string insulators on high-voltage transmission lines mainly adopts a retractable tie rod structure on one side, and is connected with U-shaped rings that can be connected to the holes of the double-string insulators through the hooks on both sides. This kind of tool for replacing double-string insulators has a large volume and many separate parts, which not only increases the difficulty of handling the tool, but also adds two separate processes during the replacement: connecting the U-shaped ring to the double-string insulator The process of connecting the holes of the plates in series and the process of hanging the double hooks of the pull rods on the double U-shaped ring...
