摘要
摩擦提升机依靠钢丝绳与卷筒之间的摩擦力实现提升容器的上提和下放,滑动事故难以杜绝。后备滑动保护装置设计过程中,提出平板式制动块和凹槽式制动块两套设计方案,应用有限元软件ANSYS对两种设计方案的制动过程进行分析,得到不同制动工况下结构的应力云图、接触应力云图和摩擦应力云图。结果显示,尽管平板式结构的应力最大值大于凹槽式结构,但凹槽式结构可以避免应力集中和钢丝绳纵向滑动的情况,且凹槽式结构更适用于工业应用。
The friction hoist depends on the friction between the wire rope and the drum to enhance the lifting and lowering of the container, so that the sliding accident is difficult to eradicate. Aiming at the design of backup sliding protection device, two schemes of flat brake block and groove brake block have been designed. In order to study their performance, the finite element software ANSYS has been used to analyze braking processes of the two design programs, and the structural stress nephogram, contact stress nephogram and friction stress nephogram under different braking conditions have been obtained. The results show that although the maximum stress of flat structure is larger than that of groove structure, groove structure can avoid stress concentration and longitudinal slip of steel wire rope, and groove structure is more suitable for industrial application.
