After the winding of the grounding wire is completed , you can push the first push rod to push the reel to the designated place, then close the electromagnetic disk controller to disconnect the electromagnetic chuck from the power supply, and then extend the piston rod of the hydraulic cylinder to drive the upper support rod to swing to the left and tilt to a certain extent At this time, it is easy to remove the reel wrapped with the grounding wire and place it in a designated place for storage; when unwrapping the grounding wire wound on the reel, the piston rod of the hydraulic cylinder is in the extended position state, drive the upper support frame to swing to the left and tilt at a certain angle. The tilt angle here is small. At this time, the left end of the shaft is tilted downward. Set the reel wrapped with the ground wire on the shaft and slide it to the right end of the shaft to the limit. At this time, turn on the electromagnetic disk controller to connect the electromagnetic chuck to the power supply, so that the electromagnetic chuck generates axial magnetic force, and the electromagnetic chuck will move to the positioning disk on the reel and finally adsorb to the positioning disk to realize the axial direction of the reel. Positioning, and then make the piston rod of the hydraulic cylinder shrink, so that the upper support frame swings to the right and tilts at a certain angle. Push the entire retractable device to the working place, pass the free end of the ground wire wound on the reel through the corresponding cable guide, then start the motor to drive the rotating shaft to rotate, and at the same time manually push the second push rod to push the whole device to a certain extent. Speed movement, and then realize the pay-off of the ground wire, or according to actual needs, two types of ground wires can be paid out at the same time. The piston rod stretches out to drive the upper support frame to swing to the left and tilt at a certain angle, at which time the reel can be easily taken off.
