摘　　要：带回转吊的门式启闭机是一种水利水电工程中常见的机械设备,通常采用主起升机构承担对闸门的启闭、安装及检修吊运任务,采用回转吊承担对液压启闭机油缸的安装及检修吊运任务,对所在部位的金属结构设备正常运行发挥着重要作用。回转吊悬伸于门架之外作回转运动,回转吊运行时的整机抗倾覆稳定性是确保门机安全运行的必要条件。某水电站工程1 000 kN/160 kN带回转吊的双向门式启闭机通过在回转吊立柱下方增加支承轮的处理措施,提高了门机的抗倾覆稳定性,成功解决了门机抗倾覆稳定性不足的问题。The gantry crane with rotary hoist is a common mechanical equipment in water conservancy and hydropower projects.The main lifting mechanism is usually used to undertake the tasks of opening,closing,installation,and maintenance of the gate.The rotary hoist is used to undertake the tasks of installation,maintenance,and lifting of the hydraulic hoist cylinder,and plays an important role in the normal operation of the metal structure equipment.The rotary hoist overhangs outside the gantry for rotary motion.The stability of the entire machine against overturning during the operation of the rotary hoist is a necessary guarantee for the safe operation of the gantry crane.This article takes a 1000 kN/160 kN gantry crane with a rotary hoist of a hydropower station as an example.By adding supporting wheels under the column of the slewing crane,the anti-overturning stability of the gantry crane has been improved,and the problem of insufficient anti-overturning stability of the gantry crane has been successfully solved.This provides a reference for solving such problems.
