起重机是现在搬运行业中不可缺少的设备,而且其使用频率非常频繁,主梁在使用过程中会发生上拱度减少,产生超规定的旁弯,主梁腹板出现超规定的波浪变形,随着使用时间的增加,可能使主梁产生永久性变形,因此要对起重机主梁的上拱度进行检测。本文对检验检测中常用的方法进行了深入的分析和研究,总结了其适用范围。 Crane is now an indispensable transportation equipment industry, and its frequency of use is very frequent, the main girder in the process of camber will occur to reduce, resulting in over-prescribed side-bending, girder web supernormal wave deformation occurs, with With the increase of service time, the main girder may cause permanent deformation, therefore, the camber of crane girder should be detected. This article has carried on the thorough analysis and the research to the method commonly used in the inspection and examination, sums up its applicable scope.
