The invention relates to the technical field of cranes, in particular to a stand column structure of a portal crane. The stand column structure of the portal crane comprises a stand column, a guide rail is arranged on the stand column, a limiting rail is fixedly installed on the stand column, a rack is fixedly installed in the guide rail, a function box and a driving box are installed in the guiderail in a sliding mode, limiting rods are fixedly installed on the function box and the driving box, limiting rollers are rotatably installed on the limiting rods, rolling wheels are installed on thefunction box and the driving box, a driving shaft is rotatably installed in the driving box, a driving gear is fixedly installed on the driving shaft, and a gear ring is installed on the driving gearin a meshing mode. The guide rail with the rack and the limiting rail are arranged on the stand column, and the gear ring for climbing is arranged in the driving box, so that the function box can continuously move along the guide rail; and meanwhile, a rust removing plate carries out up-down rust removing and grinding on the stand column, and therefore automatic stand column maintenance work is completed, climbing operation of workers is not needed, and accidents are eradicated.
