摘要
随着钢铁企业向大型化、高速化的发展,用于钢坯吊运堆垛的电磁挂梁起重机也朝着高速、高级别、高精度、高集成和轻量化的方向发展,为此设计了一种四联卷筒电磁挂梁起重机起升机构,此机构通过钢丝绳的特殊缠绕系统与正交十字吊点旋转吊具配合,实现对钢坯90°方位交叉堆垛摆放的要求,使回转吊具不会因钢坯重心偏离回转中心失去平衡,也不会发生偏转、倾斜、摇摆现象,以及断绳坠落事故,作业运行安全、高效。四联卷筒结构使起升机构达到最简化,具有结构紧凑、质量轻、占用空间小的优点,文中给出了钢丝绳最大静拉力的计算方法。
As steel enterprises increasingly expand scale in high speed, electromagnetic suspension beam crane for billet lifting and stacking also develops rapidly, aiming for high level, high precision, high integration and light weight. In such background, a hoisting mechanism of quadruple reel structure is designed for electromagnetic suspension beam crane. The mechanism is capable of cross stacking of billets with each layer at 90 ° through coordination of special steel wire winding system and perpendicular cross rotary spreader. The rotary spreader can ensure safe and efficient operation of the mechanism, and there will be no problems such as unbalance, deflection, tilt and swinging in the case of center of gravity of billets deviating from rotation center as well as falling accidents due to rope breaking. Quadruple reel makes a simplest lifting mechanism, which is compact, light and space-saving. The paper also gives the method for calculating maximum static tensile force of steel wire.
