The operator moves the knob 370 upwards first, so that the slider 360 drives the rotating shaft 320 of the power storage gear 310 to enter the power storage groove 330, then the operator rotates the knob 370, the knob 370 drives the rotating shaft 320 of the power storage gear 310 to rotate, at this time, a torsion spring (not shown in the figure) on the rotating shaft 320 gradually stores power, after the power storage is finished, the operator pushes the knob 370 downwards, so that the slider 360 drives the rotating shaft 320 of the power storage gear 310 to enter the locking groove 340, the locking groove 340 locks the rotating shaft 320 of the power storage gear 310, the torsion spring is in a power storage state, the first pulley 240 and the second pulley 250 are not limited and can rotate randomly, and at this time, the grounding cable 230 between the first pulley 240 and the second pulley 250 is in a loose state.
Acquiring the rotation direction and the screw pitch of the spiral texture on the surface of the cable 500:
The operator lifts the installation rod 120 to lift the connection frame 100, two sensing hooks 400 on two connection hooks 200 of the connection frame 100 are hung on the surface of the cable 500, the sensing taper rod 410 on the sensing hook 400 at the moment is in contact with the surface of the cable 500, the operator pushes the installation rod 120 to rotate around the axis of the cable 500 by a certain angle with the hanging position of the sensing hook 400 as the circle center, the sensing taper rod 410 on the sensing hook 400 at the moment can move along the spiral texture on the surface of the cable 500, the distance sensor on the sensing hook 400 measures the moving distance of the sensing hook 400 to obtain the pitch of the spiral texture on the surface of the cable 500, the rotating direction of the spiral texture on the surface of the cable 500 is deduced according to the moving direction of the sensing taper rod 410, the operator rotates the driving wheel 190 according to the obtained data, the driving wheel 190 drives the driving wheel 180 to rotate, the driving wheel 180 drives the rotating wheel 170 to rotate, the threaded column 150 drives the threaded column 150 to move the two connection hooks 200 to approach or separate from each other, and thus the distance between the two connection hooks 200 is adjusted.
The ground cable 230 is spirally wound around the surface of the cable 500:
After the operator lifts the mounting bar 120 after finishing the adjustment, the mounting bar 120 drives the connection rack 100, the two connection hooks 200 on the connection rack 100 are connected with the line perpendicular to the axis of the cable 500, then the mounting bar 120 is lifted continuously, so that the ground cable 230 contacts the lower side of the cable 500 and the hook tip height of the two connection hooks 200 exceeds the height of the cable 500, then the mounting bar 120 is rotated according to the rotation direction of the cable 500, for example, as shown in fig. 12, the operator rotates the mounting bar 120 counterclockwise (the counterclockwise direction refers to the counterclockwise direction seen from top to bottom in fig. 12), the two connection hooks 200 are hung on the cable 500 by 90 degrees, the ground cable 230 at this time is spirally wound on the surface of the cable 500, and the rotation direction of the ground cable 230 is the same as the rotation direction of the spiral texture of the surface of the cable 500.
Tightening the ground cable 230:
When an operator removes the installation rod 120, since a pull rope (not shown in the figure) is arranged between the installation rod 120 and the knob 370, when the installation rod 120 is removed, the pull rope on the installation rod 120 can pull the knob 370 to move downwards, the knob 370 drives the sliding block 360 to move downwards, the sliding block 360 drives the rotating shaft 320 of the power storage gear 310 to enter the rotating groove 350, meanwhile, the power storage gear 310 is meshed with the second pulley 250, the rotating shaft 320 of the power storage gear 310 is not limited any more, the power storage gear 310 drives the second pulley 250 to rotate under the action of the torsion spring, the second pulley 250 and the first pulley 240 tighten the grounding cable 230, each of the conductive cables 231 of the grounding cable 230 is tightly wound on the surface of the cable 500, and the specific state is shown in fig. 2, so that the contact area between the grounding cable 230 and the cable 500 is increased, and the connection strength of the two is higher.
