The Baiyun Iron Mine currently has 9 WK-10M3 electric shovels, including 6 in the main mine and 3 in the east mine. Since its commissioning, the WK-10M3 electric shovel has been used extensively at the Baiyun Iron Mine. 3 The slewing gears of electric shovels frequently experience tooth breakage. Replacing the slewing shaft and bearings requires disassembling the slewing wheel. During pallet installation, due to limited space and the pallet's weight, two people are needed to support it with chisels. Furthermore, its high position makes alignment difficult, resulting in wasted time and effort, significantly impacting production efficiency, reducing equipment operating efficiency, and markedly increasing the workload of maintenance workers. Therefore, its proper operation and efficiency directly affect the achievement of production and operational goals. This adds to the cumbersome maintenance procedures and increases labor intensity. To improve operational efficiency and reduce labor intensity, we implemented technical improvements, resolving the difficulty in aligning the slewing wheel. Based on the above, we custom-designed a bracket for installing the slewing wheel pallet. Utility Model Content
