Base of a three-dimensional shelf

Abstract

The invention discloses a base of a stereoscopic shelf. The base comprises a bottom plate, wherein, a U-shaped positioning column is arranged on the bottom plate, and a plurality of front connecting holes arranged longitudinally are arranged on the bottom surface of the U-shaped groove of the U-shaped positioning column. The bottom plate is also provided with a nut connecting plate, the nut connecting plate is located at the middle part of the U-shaped groove of the U-shaped positioning column, the nut connecting plate is provided with a nut plate connecting hole corresponding to the front connecting hole, and the hole end face of the nut plate connecting hole is provided with a fixing nut. The bottom plate is also provided with a tubular column, and a plurality of corresponding side connection holes are arranged on the two sides of the tubular column. The shelf assembled with the base has the advantages of large bearing tonnage, convenient installation and easy adjustment, ensures theaccuracy of the first layer of the shelf, reduces the welding deformation of the direct welding between the long column and the base, and improves the appearance of the shelf.

Description

technical field [0001] The invention relates to a three-dimensional shelf for storage and storage, and more specifically relates to a base of the three-dimensional shelf. Background technique [0002] At present, the shelves in China's logistics industry generally adopt a single cargo unit composed of columns, flat diagonal braces, and pendants (beams). The storage carriers such as pallets are directly stored on the beams, which meets the structure of the domestic lifting and extracting stacker. It has the advantages of simple and fast construction, durability, and low engineering cost. However, each cargo compartment of the storage structure is independent, and all loads are concentrated on the pendant, which cannot meet the storage of heavy tonnage and large span cargo. In modern warehouse automation management, there are high requirements for the stability and accuracy of warehouse shelves. The current conventional design of the column fixed bottom plate is generally di...

AI Technical Summary

Problems solved by technology

The current conventional design of the column fixed bottom plate is generally directly welded by the bottom plate and the column. The design disadvantage of this structure is: because the column is very high, the end face of the column is directly welded to the bottom plate, the welding deformation is large, and it is easy to cause strength after grinding. insufficient

Moreover, the welded bottom plate is only used for three-dimensional storage shelves with generally small load-bearing capacity, and cannot meet the requirements for the use of heavy-duty and large-tonnage shelves.
