Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stacker component equipment, in particular to an ultra-heavy cargo platform lifting mechanism. Background Art
[0002] With the increasing use of heavy-duty vertical warehouses, the cargo on the cargo platform of the vertical warehouse stacker is also getting heavier, which puts higher and higher requirements on the load-bearing capacity of the stacker. As the load continues to increase, the load-bearing capacity of the wire rope that pulls the cargo platform up and down also increases. The usual practice is to select a wire rope with a corresponding breaking force as the load-bearing capacity increases. The outer diameter of the wire rope will become larger and larger. At the same time, the diameter of the movable pulley and the fixed pulley will also become larger, and the occupied structural space will increase. At the same time, the thicker the wire rope and the larger the pulley, the greater the friction at the relevant position, further increasing energy consumption. In addition, the larger the wire rope, the longer the procurement cycle will be, which may affect the delivery time of the project in actual application. Utility Model Content
