They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the utility model.

[0037] In this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Example:

[0040] like Figure 1 As shown, an embodiment of the present application discloses a lightweight column structure, which is a component of a stacker and is used on high-rise and multi-story floors with low load-bearing capacity; it is suitable for dense storage systems with high warehousing efficiency and small site space, and it has a U-shaped structure, including: two U-shaped plates 1 and two connecting plates 2.

[0041] The opening sides of the two U-shaped plates 1 are arranged opposite to each other; the two connecting plates 2 are arranged parallel to each other and are arranged between the U-shaped plates 1, and are specifically welded to the ends of the opening sides of the U-shaped plates 1, thereby reducing the processing cost and facilitating production and assembly. The connecting plates 2 have a plurality of hollow grooves 21 and a plurality of reinforcing ribs 22, and the hollow grooves 21 and the reinforcing ribs 22 are alternately arranged along the axis direction of the column.

[0042] It should be noted that, through force analysis, it can be known that when the column is actually used, the U-shaped plates 1 at both ends are subjected to a higher bearing capacity, while the connecting plate 2 in the middle is subjected to a lower bearing capacity.

[0043] The utility model can significantly reduce the overall weight by arranging hollow grooves 21 on the connecting plate 2 without greatly affecting the overall supporting strength; and a plurality of reinforcing ribs 22 are formed on the connecting plate 2 by stamping, which can improve the local structural strength and rigidity without increasing the weight, so that it can withstand greater forces and loads. The two cooperate with each other, which not only ensures the actual use effect, but also carries out a lightweight design for the columns, thereby reducing the weight of a single machine, thereby reducing the ground bearing requirements, and can be used in high-rise and multi-story floors with low bearing capacity, and the overall structure is compact, suitable for layout in occasions with small space, which greatly expands the scope of application.

[0044] In some embodiments, Figure 1 and Figure 3 As shown, the cross section of the reinforcing rib 22 is a semicircular structure and is concave toward the inside of the column. The semicircular cross section can disperse stress distribution well and avoid stress concentration in a certain area, thereby improving durability and service life, but it is not limited to this, and can also be an ellipse or other shapes, without specific limitation.

[0045] In some embodiments, Figure 2 As shown, the hollow groove 21 is in an isosceles trapezoidal shape, and the axis of the hollow groove 21 is perpendicular to the axis of the column; the plurality of hollow grooves 21 are evenly spaced and arranged in meshing relationship along the axis of the column.

[0046] Specifically, the above design can maximize the removal of excess material on the connecting plate 2, and make the overall shape regular, the force distribution uniform, avoid stress concentration, ensure the overall support effect, improve the impact resistance, and have high structural stability.

[0047] Based on the above solution, the distances between the upper and lower bottom edges 211 of the hollow groove 21 and the side edge of the connecting plate 2 are equal. This design arranges the hollow groove 21 in the center of the connecting plate 2, balances the structural strength and rigidity of the left and right sides of the connecting plate 2, and improves the overall bearing support capacity.

[0048] Preferably, the inner corners of the hollow groove 21 are all provided with arc chamfers 212. The arc chamfers 212 can disperse the stress distribution at the inner corners and avoid stress concentration, thereby improving stability, durability and service life.

[0049] Based on the above scheme, if Figure 2As shown, the reinforcing rib 22 is linear and parallel to the adjacent side waist edge 213 of the adjacent hollow groove 21. This design allows the reinforcing rib 22 to evenly enhance the strength and rigidity of the plate between two adjacent hollow grooves 21, and is easy to stamp and form, and convenient for production and manufacturing.

[0050] In some embodiments, Figure 3 As shown, the U-shaped plate 1 is an integrally formed part, including: a side plate 11 and two bent plates 12 .

[0051] The side plate 11 is a flat plate, which makes the column shape more regular, but is not limited to this, and can also be a curved plate or other forms, so as to improve the support strength, without specific limitation;

[0052] The two bending plates 12 are symmetrically arranged at the two ends of the side plate 11 ; the two bending plates 12 are gradually bent inwards and then butted against the connecting plate 2 .

[0053] Specifically, compared with the traditional concave structure, the structural design of the U-shaped plate 1 increases the cross-sectional area, thereby improving the strength and rigidity, enhancing the supporting effect, and ensuring the structural stability.

[0054] Based on the above scheme, if Figure 3 As shown, in order to improve the regularity of the exterior of the column and the stability of the connection with the connecting plate 2, the bent plate 12 includes a connection section 121, a middle section 122 and a straight section 123.

[0055] Specifically, one end of the docking section 121 is fitted onto the outer side of the connecting plate 2. This structural design enables a large contact area, a high welding strength and easy operation. The other end of the docking section 121 is connected to the middle section 122. After the middle section 122 expands outward, it is connected to the side plate 11 via the straight section 123. This structural design enables the appearance of the column to have a high degree of regularity.

[0056] Exemplarily, the middle section 122 is a flat plate, which makes the shape of the column more regular, but is not limited to this. It can also be a curved plate or other forms to improve the supporting strength, without specific limitation.

[0057] Preferably, the butt section 121 and the straight section 123 are both perpendicular to the side plate 11 . This structural design further improves the regularity of the shape of the column.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
