【摘要】：宝钢COREX炼铁工程引进的Maxoflex波状挡边带式输送机是上料主皮带，用于输送球团矿、块矿等物料。在提升产量的过程中，发现其实际输送能力与设计能力存在明显差异，影响整个COREX炉产量。因而产生了本文所要研究的问题：在现有设备条件下，通过改进寻找最优的方案，提升输送能力，并确保设备长期稳定的运行。论文首先对Maxoflex波状挡边带式输送机的结构及技术参数作了概要性地介绍，再分析造成Maxoflex波状挡边带式输送机输送能力不足的原因。针对输送能力不足的原因提出并选择最优的方案——维持带速，增加电机功率。并针对方案中可能存在的部件载荷能力问题进行分别探讨：复核减速机在电机大功率下的峰值扭矩及热容量；用Solidworks软件分析运行时液力偶合器泵轮强度，并用实验校核了偶合器的热容量。其次，在输送能力提升后，凸弧段托辊及传动滚筒在运行过程中发生故障。通过理化分析、受力分析等方法对这些现象分别进行故障原因分析，并对评估这些部件失效是否与输送能力提升后输送机受力增大有关，然后根据分析结果分别提出了部件改进方案。
[Abstract]:The Maxoflex bellows belt conveyor imported from the COREX ironmaking project of Baosteel is the main belt for conveying pellets, blocks and other materials. In the process of increasing the output, it is found that there is obvious difference between the actual conveying capacity and the design capacity, which affects the output of the whole COREX furnace. Therefore, the problem that this paper will study: under the existing equipment conditions, by improving to find the optimal scheme, improve the delivery capacity, and ensure the long-term stable operation of the equipment. In this paper, the structure and technical parameters of Maxoflex corrugated belt conveyor are introduced briefly, and then the reasons for the shortage of conveying capacity of Maxoflex bellows belt conveyor are analyzed. According to the reason that the transmission capacity is insufficient, the optimal scheme-maintaining the band speed and increasing the power of the motor is put forward and selected. The problems of the load capacity of the components in the scheme are discussed respectively: check the peak torque and thermal capacity of the reducer under the high power of the motor; The pump wheel strength of hydraulic coupling is analyzed by Solidworks software, and the thermal capacity of coupling is checked by experiment. Secondly, when the conveying capacity is improved, the protruding arc roller and the drive roller break down in the process of operation. By means of physical and chemical analysis, force analysis and other methods to analyze the causes of these phenomena respectively, and to evaluate whether the failure of these components is related to the increase of the conveying capacity of the conveyor. Then according to the results of the analysis, the improvement scheme of the components is put forward respectively.
