The operating mechanism at the bottom of the stacker bears the quality of the whole machine.Under the action of its own driving motor,it drives the whole stacker to run along the running track direction,and works together with the lifting mechanism and fork to complete the movement of goods storage and withdrawal.The operating mechanism is an important structural part of the stacker,and its mechanical properties have an important influence on the overall performance of the stacker,and its stiffness is of decisive significance to the accuracy of the positioning of the stored goods.Therefore,theoretical research and mechanical analysis on the operating mechanism of the stacker are necessary.In this paper,the design of three mainstream stacker operating mechanisms at home and abroad was compared and analyzed,and the deformation of stacker operating mechanisms under these design forms was solved by theoretical calculation and simulation respectively,and the application scope,advantages and disadvantages,design details and so on of various design schemes are introduced and analyzed.
