Description

Technical Field

[0001] The utility model relates to an elevator, in particular to a storage elevator. Background Art

[0002] Elevators are used in warehousing systems to transport goods across multiple floors. Elevators can lift goods, eliminating the need for manual labor and overcoming the limitations of shuttle vehicles for single-layer transport. Elevators can improve cargo transfer efficiency, especially for bulk goods.

[0003] The Chinese patent document with patent number CN116238832A discloses an elevator for logistics warehousing, which specifically discloses that it includes a lifting mechanism, on which a telescopic feeding platform is installed. The lifting mechanism drives the telescopic feeding platform to realize the distribution of materials on each layer of the shelf. The telescopic feeding platform is provided with a power transmission line. When loading and unloading goods, the upper surface of the power transmission line is aligned with the storage surface of the shelf on that layer, the power transmission line is started, and the goods are transported to the storage surface of that layer, thus completing the loading of the goods. It has the following shortcomings: the goods to be loaded and unloaded are directly placed on the telescopic feeding platform, the amount of goods to be loaded and unloaded each time is small, and the goods cannot be stacked on the power transmission line. If the whole pallet of goods is directly placed on the telescopic feeding platform and moves up and down with the lifting mechanism, there is a safety hazard that the pallet is easily offset or falls off the telescopic feeding platform.

[0004] Therefore, it is necessary to propose further solutions. Utility Model Content
