焦作某热电厂2×1.2万kW机组的逆流式自然通风冷却塔。淋水面积600m~2,塔高42.0m,最大半径16.0m,构件柱距为4.10m,构件布置紧凑,机械化施工难度较大,见图1。构件最大重量2.06t,其他构件重量均小于1.70t。构件安装总高度9.0m。根据前述务件,采用起重量Q=3.0t,起升高度H=24.0m的电动葫芦作起重机械,解决了大型机械施工困难的问题。取得了较好的经济效益。一、悬挂式单轨吊的布置利用冷却塔风筒顶部挑
A counterflow natural draft cooling tower for a 2 × 12,000 kW unit in a thermal power plant in Jiaozuo, China. The water shower area is 600m~2, the tower height is 42.0m, the maximum radius is 16.0m, and the column spacing of the components is 4.10m. The layout of the components is compact, and the mechanized construction is difficult. The maximum weight of the component is 2.06t, and the weight of other components is less than 1.70t. The total height of component installation is 9.0m. According to the foregoing articles, the electric hoist with a lifting weight of Q=3.0t and a lifting height of H=24.0m is used as a lifting appliance, which solves the problem of difficulty in construction of large-scale machinery. Has achieved better economic benefits. First, the arrangement of the suspended monorail crane utilizes the top of the cooling tower
