转炉副枪升降移动导向辊机构分析及设计优化

Failure Analysis and Design Optimization of Auxiliary Gun Lifting and Moving Guide Roller

本文针对现场副枪升降移动导向辊常见的问题进行分析,根据副枪各机构,作图模拟副枪本体在移动导向辊内可能出现的运行轨迹,并结合现场实际情况,分析发生故障的薄弱点。通过轨迹模拟分析可知:原有的设计理论上并不会出现副枪本体过度偏移至某一方位,导致在安装副枪探头下降时副枪接插件偏离在导向斗之外,从而导致探头安装失败,甚至出现撞坏副枪等问题。同时发现由于导向盘原设计结构存在缺陷,有可能会导致副枪本体出现异常磨损情况。在得出结论后,在原有设计基础大体不变的条件下,对薄弱环节进行设计优化,加强现场设备运行稳定性。

This paper analyzes the common failures of the auxiliary gun lifting and moving guide roller on site. According to the mechanisms of the auxiliary gun, it simulates the possible running track of the auxiliary gun body in the moving guide roller, and analyzes the weak points of the failures based on the actual situation on site. Through trajectory simulation analysis, it can be seen that in the original design theory, the auxiliary gun body will not be excessively shifted to a certain direction, which will cause the auxiliary gun connector to deviate from the guide bucket when the auxiliary gun probe is lowered, resulting in the probe installation failure, or even the auxiliary gun is damaged. At the same time, it is found that the original design structure of the guide plate has defects, which may lead to abnormal wear of the auxiliary gun body. After the conclusion is drawn, under the condition that the original design basis is basically unchanged, the optimization scheme is designed for the weak link to strengthen the operation stability of the field equipment.
