鉴江高岭拦河闸2×250 kN固定卷扬式启闭机设计

Design for 2×250 kN fixed winch hoists for the Jianjiang Gaoling Sluice

介绍了鉴江高岭拦河闸重建工程升卧式工作闸门2×250 kN固定卷扬式启闭机的整体布置和主要技术参数。对启闭机的总体设计方案和零部件的选型进行了比较和分析,对较长同步轴的引出位置和防挠支撑方式进行了探讨并给出解决方案,对水平受力的多支点机架基础荷载通过ANSYS软件进行了计算分析,并提出水平抗滑移措施。2×250 kN固定卷扬式启闭机安装后,各项技术指标均满足设备招标书和规范规定;各类安全保护装置动作准确可靠,钢丝绳在卷筒上多层缠绕排列均匀;闸门升降顺利,未出现偏斜现象,闸门从直立到平卧以及从平卧到直立的状态转换平滑、连续;同步轴运行平稳无振动,说明同步轴的引出位置和中部支撑设置合理。

The overall layout and main technical parameters of 2×250 kN fixed winch hoists for the lifting-lying operating gate of Jianjiang Gaoling Sluice Reconstruction Project are introduced.The overall design scheme and component selection of the hoist are compared and analyzed.The extraction position and the stiffener selection for the long synchronous shaft are discussed and the solution is given.The base load for multi-pivot bracket under horizontal force is calculated and analyzed by ANSYS software,and measures for anti-slip on horizontal direction are proposed.After the installation of 2×250 kN fixed winch hoists,all technical indicators have met the bidding documents and specifications;all kinds of protection devices are operating accurately and reliably,and the steel wire ropes are evenly wound on the reel;no deflection occurs during lifting and the state of the gate switches between upright and lying smoothly;the synchronous shaft runs smoothly without vibration.These indicate that the arrangement for extraction position and the central support of synchronous shaft are reasonable.
