Description

Technical Field

[0001] The utility model relates to the technical field of warehousing and logistics equipment, and particularly relates to a column for a heavy-duty warehousing robot. Background Technique

[0002] The column device of warehousing and logistics equipment is the main load-bearing part of the equipment, which has the characteristics of high strength and strong bending resistance. In the production design of the column, in order to reduce the deformation requirements of the raw materials for the column, the design of increasing the thickness of the material and enlarging the cross-sectional size of the column is usually adopted to improve the deformation of the column.

[0003] For example, in the column structure of a common warehousing robot stacker, the general stacker column structure in the industry is made by welding national standard square tubes. When the length exceeds a certain value, due to the uncontrollable bending deformation of the raw materials, it is easy to cause that after the column is processed and installed, its precision parameter requirements cannot meet the industry standard specification values, affecting the operation and use of the equipment and increasing the difficulty of equipment installation and debugging. If the design of increasing the thickness of the column plate and enlarging the cross-sectional size of the column is adopted to improve the deformation of the column, the stacker column made in this way will be relatively heavy, thus reducing the operation performance parameters of the stacker to a certain extent.

[0004] A connecting device, a column device and a stacker (publication number: CN218433764U) are retrieved. A connecting device, a column device and a stacker provided by this utility model, since the two ends of each guide rail mechanism have been positioned, there is no need to assemble with bolts and other fasteners subsequently, greatly improving the assembly efficiency of the stacker column device.

[0005] A column assembly for a stacker (publication number: CN212424301U) is retrieved again. The structure of this utility model is simple, the weight is reduced without losing the bearing strength, and all are bolt-fastened, which is convenient for maintenance. At the same time, the material is selected as aluminum alloy material, which is convenient for the painting process, and can also be adapted to motors with lower energy consumption, improving the horizontal running speed of the stacker.

[0006] For the patents retrieved above, namely a connecting device, a column device and a stacker (publication number: CN218433764U), due to the use of positioning grooves for docking, the processing cost of the positioning grooves is high, the docking labor intensity is large, and on-site docking is very inconvenient. For a column assembly for a stacker (publication number: CN212424301U), the material is selected as aluminum alloy material, and all are bolt-fastened in the connection method. On the one hand, although the weight is reduced due to the aluminum alloy material, its strength is low and it is not suitable for heavy-duty equipment. On the other hand, all are bolt-fastened. Due to the existence of assembly gaps, the installation accuracy is low. After normal operation, due to the loosening of the gaps, it will affect the docking accuracy of the tracks, thus affecting the normal operation of the equipment. Therefore, we need to propose a column for a heavy-duty warehousing robot. Summary of the Utility Model

One end of the first inner connecting rod 106 is inclined and fixedly installed on the sides of the upper and lower adjacent groups of the first horizontal connecting rods 103;

[0039] The lower column 2 includes a third vertical plate 201, a fourth vertical plate 202, a second horizontal connecting rod 203 and a second inner connecting rod 205. There are two groups of the second horizontal connecting rods 203, and the two groups of the second horizontal connecting rods 203 are symmetrically fixed on the inner sides of the third vertical plate 201 and the fourth vertical plate 202. One end of the second inner connecting rod 205 is installed on the second horizontal connecting rod 203, and the other end of the second inner connecting rod 205 is fixedly installed on the inner side of the third vertical plate 201.

[0040] It should be noted that the column generally adopts structural members such as the first inner connecting rod 106, the inclined connecting rod 104, the first horizontal connecting rod 103, the second horizontal connecting rod 203 and the second inner connecting rod 205, and is assembled with fasteners.
