Description

Technical Field

[0001] The present invention relates to the technical field of logistics warehousing equipment, and more precisely, to a turnover machine applicable to the column of a stacker crane. Background Art

[0002] With the popularization and promotion of automated stereoscopic warehouses in the logistics warehousing industry, the requirements for the efficiency and operation stability of automated stereoscopic warehouses are getting higher and higher. The stacker crane is the core equipment of an automated stereoscopic warehouse and belongs to a special-purpose lifting and transportation machine. It mainly realizes the horizontal and vertical running functions through the ground track and its own column, and uses devices such as a universal fork to realize the grasping, handling, and stacking operations of unit goods. The column of the stacker crane is one of the core components of the stacker crane, generally made of square tubes, rectangular tubes, or steel plates welded together. The cross-sectional size of the stacker crane column is large and the height is very high. Moreover, with the continuous increase in the scale of automated stereoscopic warehouses, in order for the stacker crane to adapt to faster and higher working conditions, the cross-sectional size and length of the stacker crane column have also been continuously increased, thereby increasing the difficulty of the production and processing of the stacker crane.

[0003] During the production process of the stacker crane, the column needs to be turned over. Currently, the turning operation generally uses a sling in cooperation with a traveling crane. The column is placed flat on the workbench. One end of the sling is fixed to the column, and the other end is fixed to the hook of the traveling crane. Then, the traveling crane is operated to obliquely pull the sling to drive the turning of the column cross-section. In the implementation process of the current scheme of the traveling crane obliquely pulling and turning the column, due to the large size and weight of the column, after the center of gravity moves from one side of the fulcrum to the other side, uncontrollable impacts will occur between the column and the workbench, easily causing damage and deformation of the column, being very dangerous to the staff, and having a relatively low working efficiency.
