Description
Technical Field
[0001] The utility model relates to the field of stackers, in particular to a stable three-dimensional warehouse stacker. Background Technique
[0002] A stacker is a tool for placing goods in a large warehouse. In order to increase the inventory capacity, the shelves used in large warehouses are not only tall but also have small shelf spacings, so generally a stacker is needed to place goods on the shelves. The lifting structure of the existing stacker mainly uses wire pulling. The lifting platform is pulled by a wire to make the lifting platform rise, and the lifting platform will also descend under the action of gravity.
[0003] At present, since the steel wire rope of the existing stacker only pulls the part of the lifting platform close to the stacker main body, when the weight of the goods is large, the lifting platform exerts a force on the steel wire rope several times the self-weight of the goods under the action of the lever away from it, making the steel wire rope bear a large force, which not only reduces the service life of the steel wire rope but also has certain potential safety hazards. Therefore, it is necessary for us to improve such a structure to overcome the above defects. Content of the Utility Model
