Abstract
This utility model discloses a special tool device for disassembling the synchronous pulley of a grinding mill, relating to the field of grain processing machinery maintenance technology. It includes a left semi-circular disc, a right semi-circular disc, and a pneumatic adjustment component for adjusting the distance between the left and right semi-circular discs. Multiple pneumatic valves for tensioning the synchronous pulley are installed on the left and right semi-circular discs. A retractable handle for improving torque transmission efficiency is detachably installed on either the left or right semi-circular disc. This utility model automatically adjusts the distance between the left and right semi-circular discs through the pneumatic adjustment component. This structure has high interlocking strength, effectively preventing slippage of the clamped synchronous pulley. The retractable handle reduces operational intensity, improves torque transmission efficiency, and is ergonomically optimized. Utilizing the lever principle (lever ratio 5:1), force is applied through the retractable handle (operating force < 50N) to rotate the synchronous pulley, achieving rapid disassembly.
