近年来,市场对电站汽机房吊装发电机定子用桥机需求量越来越多,特别是80t~130t等中等吨位的电站桥式起重机占据市场份额较大。本文主要从降低轨顶以上高度H1为切入点,通过对比几种典型的电站桥式起重机结构形式,从构造特点、受力情况、加工工艺等多方面分析,提出一种电站用桥机的低净空设计思路,提高电站用桥机的市场竞争力。
In recent years, there is an increasing demand for the stator bridge machine used in the hoisting machine of a steam turbine room of a power station in the market, especially the bridge crane with medium tonnage of 80t ~ 130t occupies a large market share. This article mainly from the lower height above the top of the track H1 as the starting point, by comparing several typical types of power station bridge crane structure, from the structural characteristics, stress conditions, processing technology and many other aspects, proposed a power plant bridge machine low Clearance design ideas to improve the power station bridge machine market competitiveness.
