Abstract
This utility model relates to the field of overhead crane coupling technology, specifically an overhead crane coupling replacement device. The device includes a support base plate, with an electric push rod fixedly connected to the top of the support base plate. The telescopic end of the electric push rod is equipped with an adjustment mechanism, and the top of the adjustment mechanism is equipped with a clamping mechanism. This utility model utilizes a synchronous pulley, a synchronous belt, and sliding clamps. By starting a second rotating motor, the output of the second rotating motor drives the synchronous pulley to rotate. The rotation of the synchronous pulley drives two second lead screws to rotate via the synchronous belt. The rotation of the two second lead screws causes two sliding clamps to move downwards, clamping the coupling using the sliding and fixed clamps. Then, the bolts on the half-coupling can be removed, preventing the half-coupling from falling off during bolt removal and enhancing the safety of coupling disassembly.
