Method for resetting tool of aluminium electrolysis multifunctional overhead traveling crane and device thereof

The present invention discloses a method of electrolytic tending tools and resetting means. Which is fixed on the switch detects the sensing signal with the actual position of the tool is moved up and down the inductor, when the actual amount of decline Δss inductor is greater than the allowable amount Sy decline, the switch sends a signal detection signal and a preset alarm driving tool automatically reset to the initial height. The method according to the present invention comprises a fixing device made of sensing the movement of the tool body (1) (2); (4) and the sensing signal switch includes a sensing signal switch portion of the tool in a fixed guide (3) of ( 5) and allows fell position sensor switch (8); the sensing signal switch and allows the switch and the sensing signal falling position sensing operation switching switch (6) and the tool lever (7) is connected. Prior to the present invention can be automatically reset to a decline in the height of the crane dangerous tool, and the lower end of the tool to avoid the upper portion of the electrolytic cell mechanism of mechanical collision.
