摘要
大跨度起重机行走机构因两侧行走机构运行不同步会引起偏斜,此偏斜会引发行走机构车轮啃轨而出现车轮或轨道损坏,从而导致正常运行受阻,严重时可能会发生安全事故。针对上述问题给出了几种自动纠偏系统控制方案,介绍了纠偏系统的控制原理,并详细介绍了各种纠偏控制系统硬件组成、安装简图、实现方法及其优缺点,以便于起重机研发设计人员更好的开展工作。
Asynchronous travelling on both sides of travelling mechanism can lead to deflection of large span crane. As a consequence, deflection can induce rail gnawing of travelling wheel or rail damage to prevent normal travelling or more seriously to bring about safe accident. As regards the above-mentioned problem, several control schemes on automatic correction system was provided,and the working principle of the system as well as its hardware composition, installation diagram sketch, installing method and its pros and cons were introduced in detail, so that research and design personnel of crane to work better.
