Abstract

A tool special for stay manufacture comprises a stay holding bender, a stay clamp tightener and a stay fixing device. The stay holding bender comprises an upper holding bend mechanism and a lower holding bend mechanism, the lower end of the upper holding bend mechanism is rotatably connected to the upper end of the lower holding bend mechanism, the upper holding bend mechanism comprises an upper holding bend column, the top of the upper holding bend column is fixedly connected to an upper connecting bolt arranged vertically, and the rear side of the upper holding bend column is fixedly connected to a bending groove. The tool provides proper holding bending angle, the standard size meets the process standard, detachable handles of two ends are arranged, the arc is limited through a pulley, and friction damage is reduced.

Description

technical field [0001] The invention relates to a tool for on-site fabrication of power transmission lines. Background technique [0002] In the field of electric power, the stay wire is used to connect the ground and the end of the tower to form an effective traction and fixation for the tower. At the connection between the stay wire and the ground, it is necessary to bend the back of the stay wire back to the main stay wire, and wrap the back and the main stay wire with an iron wire to fix them. Due to the high rigidity of the stay wire, it is not easy to bend, and the operator needs a lot of strength to bend it. And it is not easy to control in the operation, and the upper and lower wire clips on the backguy made do not meet the construction standards, and the curved arc of the backguy that is held is not beautiful and not standard, and also damages the backguy and damages the galvanized layer. The original construction method is exhausted if one person makes a few, and...
