摘要
在调研传统液压自动抓梁在水利水电工程中应用情况的基础上,分析了液压自动抓梁吊轴中心与水工钢闸门吊耳孔中心对位的原理与过程。并针对传统液压自动抓梁在对位设计上存在的不足,提出了一种基于"柔性调速"的设计思想,采用"过程控制"以实现液压自动抓梁吊轴中心与闸门吊耳孔中心自动对位的结构设计。该新型结构对传统液压自动抓梁对位装置系统进行了必要的改进,既可较好地保证对位精准度,同时也有效地保护了闸门及液压自动抓梁的设备安全。
According to the actual application of the hydraulic automatic grab beam in water conservancy and hydropower pro- jects, the alignment principle and process of the hydraulic automatic grab beam is analyzed. To solve the defects of alignment de- sign in the traditional automatic hydraulic grab beam, a new alignment structure based on ＂flexible control of lowering speed＂ is proposed. The ＂ process control＂ is put forward to realize the alignment between＇the automatic hydraulic grab beam and the lug of gate. The new structure can improve the alignment device of the traditional automatic hydraulic grab, which could ensure the a- lignment accuracy and also protect the safety of gate and the automatic grab beam.
