Abstract

The invention discloses an electric power stringing line crossing device. The device comprises a threading device, a pull rope, a variable-pitch rope, a side face fixing device, a fixed pulley, a movable pulley, a pulley, a supporting column, a fixed notch, a sliding connecting rod, a supporting column, a fixed pulley, a supporting set and a linkage set. The supporting set comprises the supportingcolumn, the side face fixing device, an upper fixing plate and a variable-pitch rope fixing device. The linkage set comprises the threading device, the movable pulley, the fixed pulley, a wire connector, the sliding connecting rod and a linkage rotating wheel; the supporting column is in a stand column shape, and the supporting column is made of a cement concrete material; the side surface fixingdevice is arranged above the supporting column; and the side face fixing device is of a barreled structure and is made of stainless steel materials, the side face fixing device is arranged above thesupporting column in a sleeving mode, fixing buckles are fixedly arranged on the two sides of the side face fixing device, the side face fixing device fixes a device fixing frame through the fixing buckles, the device fixing frame is of a trapezoidal structure. Maintenance, regulation and control are achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power transportation, in particular to an electric power line jumper. Background technique [0002] Overhead lines mainly refer to overhead open lines, erected above the ground, and are high-voltage transmission lines that use insulators to fix the transmission wires on the towers standing on the ground to transmit electric energy. It is convenient to erect and maintain, and the cost is low, but it is easy to be affected by weather and environment (such as strong wind, lightning strike, pollution, ice and snow, etc.) . The main components of overhead lines are: wires and lightning conductors (overhead ground wires), towers, insulators, fittings, tower foundations, stay wires and grounding devices, etc. [0003] During the use of the previous jumpers, it was not easy to regulate and operate. Contents of the invention [0004] The object of the present invention is to provide an electric power...
