The principle of this embodiment is:
the spool 52 is also subjected to reactive forces from the grid lines during tightening of the lines under force, and when the magnitude of the reactive forces from the lines is determined to be the same, it is determined that the grid lines are each of the same arc.
The plurality of fingers can be a plurality of adjacent parallel power grid lines, or a plurality of continuous lines formed by connecting the same power grid line with a plurality of binding posts continuously.
The hanger of the adjustable torque tightener 100 is connected with one of a plurality of power grid lines needing tightening and needing uniform vertical radian, the rotating handle 10 is installed on the tightener main body 50, a torque balancing device 40 is selected, the bulge 11 on the rotating handle 10 is abutted to the second end position of the balancing weight 43 of the torque balancing device 40, at the moment, external acting force is applied to the rotating handle 10, the connecting position of the assembly hole of the rotating handle 10 and the external section is used as a rotating fulcrum of the rotating handle 10, the balancing weight 43 abutted to the bulge 11 provides supporting force for the rotating handle 10 under the action of the spring 41, the ratchet 20 rotates in the clockwise direction and drives the winding shaft 52 to rotate, the spring 41 of the torque balancing device 40 is compressed at the moment, the balancing weight 43 rotates by a certain angle with the rotating shaft 42 as an axis at the horizontal position under the action of the lever principle, the counter acting force of the wire on the winding shaft 52 is increased in the process of gradually tightening the power grid lines, in order to overcome the counter acting force, the corresponding acting force needs to be applied to the rotating handle 10, the supporting force is provided by the corresponding to the bulge device 10, the supporting force needs to be provided by the supporting weight 40 is increased, the supporting force is needed to the rotating handle 10 is provided for the balancing weight 40, the supporting weight is needed to have a larger value is increased, the rotating weight is needed to the balancing weight is needed to have a certain degree is increased, and the rotating device is increased, and the balancing weight 43 is has a certain degree has a certain value is increased, and has a certain value.
And then the same operation is performed one by one on the adjustable moment tightener 100 for other power grid lines needing to tighten and unify the vertical radians, namely, the vertical radians of each power grid line can be tightened and unified to the same vertical radians as the first line.
Specifically, because the spring 41 of each moment balance device 40 has different elastic coefficients, the maximum supporting force that each moment balance device 40 can provide for the rotating handle 10 is different, and the corresponding values of the maximum reaction force of the lines to the winding shaft 52 are different, and the corresponding tightening degrees to the power grid lines are different, so that when other lines are tightened one by one in the same way as the first line, the balance weight 43 of the moment balance device 40 abutting against the protrusion 11 of the rotating handle 10 is the balance weight 43 of the same moment balance device 40 when the first line is tightened, so as to ensure that the reaction force of the power grid lines to the winding shaft 52 is equal when the protrusion 11 and the balance weight 43 fall off, and ensure that the vertical radian of each power grid line is uniform.
Because the spring 41 of each moment balance device 40 has different elastic coefficients, when the first tightening power grid line is tightened, the convex body 11 is not separated from the balance block 43 when the power grid line is tightened to the maximum extent, and the moment balance device 40 of the spring 41 with smaller elastic coefficient is selected to enable the balance block 43 to be abutted against the convex body 11 of the rotating handle 10.
Correspondingly, when the grid line is not yet tightened and the protruding body 11 is separated from the balance weight 43, the moment balance device 40 of the spring 41 with larger elastic coefficient is selected to enable the balance weight 43 to abut against the protruding body 11 of the rotating handle 10.
