The utility model belongs to the technical field of forklift manufacturing, and discloses an auxiliary device for improving
portal frame stacking efficiency. The stand column
welding part is fixedly arranged on the top surface of the bearing frame and vertically extends upwards; the rotary supporting plate is in welded
coupling connection with all the stand columns; the rotary supporting plate comprises a linkage end; the supporting end and the linkage end are perpendicular to each other and are integrally formed; in the unused state, the two supporting ends located on the bottom layer face the position between the two stand column
welding-on parts and incline upwards. One end of the connecting plate is rotationally connected with the linkage end, and the other end is coupled with the linkage end of the rotary supporting plate on the connecting plate; the combination of the load-bearing frame, the stand column seaming, the rotary supporting plate and the connecting plate forms the reliable, practical and simple
portal frame stacking auxiliary device, and the
portal frame stacking auxiliary device is mainly applied to production activities of portal frames, when semi-finished portal frames need to be stacked, operation steps are reduced, the stacking time is shortened, and therefore the working efficiency of workers is improved, and the production cost is reduced. And meanwhile, the
operation safety can be improved.
