摘要
为提高带式输送机拉紧装置配重吊装过程的便利性,对该系统进行改进设计,包括用斗车代替吊车,用动滑轮组减小受力,用定滑轮组将起升力改为水平拉力。对改进方案进行三维建模和有限元仿真。通过对2条皮带线实施改造,运行效果良好。
The weight lifting system of belt conveyor tension device is improved and designed for operating smoothly. The crane is replaced by hopper. The stress is reduced for the movable pulley group, and the force is changed by the fixed pulley group. The cable diameter is calculated according to the stress. The stability of post is analyzed and reinforced. The improved plan is designed by the three dimensional modeling and finite element simulation. Two transformation belt lines are completed and fine feedback is received.
