DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 to Figure 5 As shown, a slot-connected lifting shelf comprises a shelf frame, wherein the shelf frame has four columns 1, a pair of the columns 1 in the length direction are respectively provided with a liftable long beam 3, and a pair of the columns 1 in the width direction are respectively provided with a liftable short beam 4; the short beam 4 is connected with a lifting drive assembly for controlling the short beam 4 to be lifted and lowered along the column 1; a support bracket 5 is provided on a side of the short beam 4 facing the long beam 3, a support shaft 7 is provided on an end of the long beam 3, a slot connection structure 6 is provided on a side of the column 1 facing the long beam 3, and a switching mechanism is further provided near the end of the short beam 4, and the switching mechanism is used to control the support shaft 7 to fall on the support bracket 5 or the slot connection structure 6.

[0027] The short cross beams 4 are a pair arranged symmetrically, and the long cross beams 3 are a plurality of pairs arranged symmetrically, and the plurality of pairs of long cross beams 3 are arranged layer by layer in the shelf frame.

[0028] The slot-connected lifting rack has a simple structure and is easy to control and use. By improving the lifting drive method and the installation structure of the long crossbeam 3, the long crossbeam 3 can be controlled to move up and down and stop at the required position, which is convenient for forklifts to load and unload materials. It has good flexibility and can adjust the height of the goods by lifting. The space utilization rate of the shelf is also high.

[0029] The short crossbeam 4 is an active lifting crossbeam, which is not directly connected to the long crossbeam 3, but can be moved by the supporting bracket 5 and the switching mechanism arranged thereon to realize the movement of the long crossbeam 3; the reason for this arrangement is that only one short crossbeam is arranged on each side of the shelf, and the long crossbeam is arranged in multiple layers. The long crossbeams of each layer need to be lifted but not lifted at the same time, only need to be lifted independently, and the long crossbeams of any layer can be selected for lifting and moving under the connection of the short crossbeams, and the long crossbeams of other layers are not affected and can be relatively stably supported in the shelf frame; in this way, it is only necessary to design a lifting drive component for driving the short crossbeam to lift and lower, which can reduce the number and difficulty of arranging the driving parts.

[0030] The two ends of the long beam 3 are provided with the support shaft 7, and in a normal state, the support shaft 7 is respectively engaged and supported on the slot connection structure 6 to form a layer structure of the shelf; when it is necessary to move, the short beam 4 will move up and down to the corresponding long beam 3 under the drive of the lifting drive assembly, and the support shaft 7 can be moved to the support bracket 5 through the switching mechanism, and then the long beam 3 can be lifted and lowered together with the short beam 4. When the long beam 3 needs to be placed again, the switching mechanism will move the support shaft 7 from the support bracket 5 to the slot connection structure 6 again. The whole process is driven and driven by electric mechanized components, without the need for human participation, and the effect of saving time and labor is achieved in the process of loading and unloading goods.

[0031] The shelf can be used in a warehouse or in a container of a logistics truck, so as to facilitate the automatic loading and unloading of materials in the truck. In some embodiments, the overall dimensions of the shelf frame are: 2850mm long * 1400mm wide * 2000mm high, and the cross-sectional dimensions of the columns are approximately 75*75mm. A shelf frame of this size can be installed in a box-type logistics truck.

[0032] Furthermore, each layer of the long beam 3 is provided with a tray, which can be used to carry goods. Since the long beam can be raised and lowered, the goods carried by the tray can also be raised and lowered.

[0033] When the long cross beam 3 is connected with the column 1, the two long cross beams 3 at the front and rear form a layer of boards, each of which can accommodate two 1.2m*1.2m pallets lying flat, and each layer of boards can bear 100kg. Preferably, the shelf of this design is composed of four columns and three layers of boards.

[0034] Each shelf moves when empty (without pallets and goods), and each shelf is not required to move at the same time. The two long beams of each shelf need to move synchronously to ensure that the goods do not slide when the shelf is loaded and can be picked up by forklift. The long beam can be effectively connected with the column to realize the load-bearing function, and the load-bearing capacity is not less than 300KG.

[0035] Furthermore, the slot connection structure 6 includes an L-shaped corner plate 601 arranged on the side wall of the column 1, and the outer side of the corner plate 601 is provided with a plurality of slots 602 opening obliquely upward in sequence from top to bottom, and the slots 602 are used to connect with the support shaft 7.

[0036] The slot 602 has an opening that is inclined upward, which can well connect with the support shaft 7 to prevent the support shaft 7 from falling off, and also allow the support shaft 7 to fall out of the slot 602 when subjected to a lifting force; the slots 602 are evenly distributed in the vertical direction from top to bottom, and can support the support shaft 7 at different heights.

[0037] Furthermore, a V-shaped slope is provided on the support bracket 5, and an arc groove 501 is provided at the bottom of the V-shaped slope. The arc groove 501 is used to support the support shaft 7. Such a structure not only facilitates the support shaft to fall into the arc groove 501, but also has a limiting effect to prevent the support shaft from rolling out in the front and rear directions; a clearance distance is provided between the support bracket 5 and the slot connection structure 6, and the clearance distance allows the cam hook to pass through.

[0038] Furthermore, a rolling bearing 8 or a roller is provided at the end of the support shaft 7 .

[0039] The rolling bearing 8 or the roller is arranged so that it can rotate at the end of the support shaft, and when it falls on the support bracket 5, it is conducive to the support shaft rolling toward the arc groove while the long beam itself does not rotate. At the same time, this structure can also form a limit at the end.

[0040] Furthermore, the switching mechanism includes a first drive motor 10 arranged on the short cross beam 4 through a mounting seat 9, and the output end of the first drive motor 10 is connected to a cam hook 11, and the cam hook 11 is located in the area between the support bracket 5 and the slot connection structure 6, and the cam hook 11 is used to hook the support shaft 7.

[0041] The first driving motor 10 can drive the cam hook 11 to rotate or swing. During the rotation, the cam hook 11 can hook the support shaft 7 to allow the support shaft 7 to switch between the support bracket 5 and the slot 602 .

[0042] Furthermore, the lifting drive assembly includes a second drive motor 13, a transmission gear 14 and a rack 15. A vertical guide groove is provided on one side of the column 1 facing the short cross beam 4. A pair of racks 15 are arranged on the inner side of the guide groove. The second drive motor 13 is connected to the short cross beam 4 through a first connecting plate 12. The output end of the second drive motor 13 passes through the guide groove and is connected to the transmission gear 14. The transmission gear 14 is meshed and connected between the pair of racks 15.

[0043] The second driving motor 13 drives the transmission gear 14 to rotate. Due to the limiting and meshing of the pair of racks 15, the transmission gear 14 can move up and down relative to the pair of racks 15, thereby realizing the up and down movement of the short crossbeam 4. This driving method has a simple structure, small space occupancy, and can utilize the internal space of the column.

[0044] The first drive motor 10 and the second drive motor 13 are both in the form of a combination of a servo motor and a reducer, which can better control the speed of lifting or rotating.

[0045] Furthermore, a second connecting plate 16 is provided at the end of the short cross beam 4 , and the second connecting plate 16 extends into the column 1 and is connected to a slider 17 . The slider 17 is disposed on a slide rail 18 , and the slide rail 18 is vertically arranged on the inner wall of the column 1 .

[0046] The coordinated arrangement of the second connecting plate 16 , the sliding block 17 and the sliding rail 18 can not only play a guiding role, but also improve the connection stability and movement stability of the short crossbeam.

[0047] Furthermore, the shelf frame also includes a fixed beam 2 connected between the ends of adjacent columns 1 to form a rectangular frame structure, and a number of support plates are connected between each pair of long beams 3, so that the correlation and stability between the pair of long beams 3 on each layer are higher.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
