Operation principle:When needing to move the present apparatus, start electric pushrod elongation, drive fixed block to move up suitably
Distance, pole is set to rise suitable distance, electric pushrod is stopped, and people pushes pushing hands and the present apparatus is pushed into suitable position
Put, when needing clamping porcelain insulator, start the second motor reversal, drive the reversion of the first screw mandrel and the second screw mandrel to rotate forward, make the
One nut moves up to be moved down with the second nut, is driven top kelly to move up and is moved down with lower section kelly, when upper
When the kelly of lower section is at a distance of appropriately distance, the second motor stalls, porcelain insulator is disposed below in kelly, starts the
Two motors rotate forward, and drive the first screw mandrel to rotate forward and the reversion of the second screw mandrel, the first nut is moved down with the second nut to moving up
It is dynamic, drive top kelly to move down and moved up and clamping porcelain insulator with lower section kelly, so the clamping effect of porcelain insulator
Fruit is more preferable, when not needing clamping porcelain insulator, starts the second motor reversal and drives the reversion of the first screw mandrel and the second screw mandrel to rotate forward,
Move up the first nut to move down with the second nut, drive top kelly to move up and moved down with lower section kelly,
When the kelly of upper and lower is at a distance of appropriately distance, the second motor stop reverse, porcelain insulator is taken out, then start the second electricity
Machine rotates forward, and drives the first screw mandrel to rotate forward and is inverted with the second screw mandrel, moves down the first nut and moved up with the second nut,
When first nut moves downward, wedge, which moves downward, makes contact wheel move right, so that the first push rod moves right, drives
Pressing board moves right press shift knob after, the second motor is stopped, then start the first motor rotate forward 90 °, drive hide ash
Frame rotates clockwise 90 ° and hides ash to kelly, can be again according to above-mentioned original when also needing to carry out the clamping of porcelain insulator next time
Reason is operated.
