Abstract
With the rapid development of China's manufacturing and logistics industry, portal cranes are irreplaceable in ports, wharfs and freight yards.
The role. The graduation design is designed by a multi-purpose gantry crane. The operation mechanism is mainly used for the horizontal adjustment of the crane's working position. This design is based on the design parameters and model requirements proposed by the task book. First, the design selection is carried out, and the overall design calculation of the multi purpose portal crane is completed. Then the design calculation of the operating mechanism and the selection of the transmission parts are completed. Finally, the 3D modeling software SolidWorks is used to model the main parts of the operating mechanism. In order to intuitively reflect the components of each component.
Key Words: Multi-purpose portal cranes; overall design; operating mechanism design
