升降机卷筒安全圈处钢丝绳断丝状况及受力分析

Analysis of Wire Rope Broken and Force Analysis at the Safety Ring of the Lift Drum

分析了一台升降机电动葫芦卷筒上的钢丝绳断丝原因,应用欧拉公式分析了钢丝绳在卷筒上的受力情况,构建了升降机钢丝绳的动力学模型。通过计算钢丝绳在3种不利工况下的安全系数,分析了可能存在的安全隐患,并提出了预防卷筒上的钢丝绳断丝、安全圈检验、减小冲击载荷等方面的建议。

The cause of wire broken on the electric hoist drum was analyzed, the force condition of wire rope on drum was analyzed by Euler formula, and the dynamic model of hoist wire rope was built. By calculating the safety factor of the wire rope under three unfavorable conditions, the possible safety risks were analyzed, and suggestions for preventing wire rope breaking, safety ring inspection and reducing impact load were put forward.
