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 magnetic lock type lifting shelf includes a shelf frame, 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 end of the short beam 4 is connected to a driving component through a first connecting plate 8, the output end of the driving component passes through the first connecting plate 8 and is connected to a transmission gear 9, and the transmission gear 9 is matched with the directional rack 10 on the column 1; the end side of the short beam 4 and the end of the long beam 3, and the end side of the long beam 3 and the column 1 are respectively connected by magnetic locks.

[0027] The magnetic lock lifting shelf improves its lifting connection structure and driving method so that the long crossbeam 3 with load-bearing function can be freely lifted up and down and parked at a required height, which is convenient for loading and unloading goods. At the same time, the structure is relatively simple, occupies less space, does not affect the storage of goods in the shelf, and is easy to use and control.

[0028] By cooperating with the transmission gear 9 and the directional rack 10, the transmission gear can be moved up and down relative to the directional rack under the drive of the drive motor, thereby realizing the up and down movement of the short crossbeam 4; this driving method has a simple structure, small space occupancy, and can also utilize the internal space of the column.

[0029] The short beam 4, the long beam 3 and the column 1 are connected by magnetic locks, and a variety of connection combinations can be achieved. In the normal loading state, the long beam 3 is connected to the column 1 by magnetic locks and disconnected from the short beam 4, and a pair of the long beams 3 can form a layer structure; 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 driving component, and connect to the long beam 3 through the magnetic lock while the long beam 3 is disconnected from the column 1, and then the long beam 3 can be raised and lowered with the short beam 4. When the long beam 3 needs to be placed again, the magnetic lock on the long beam 3 is connected to the column 1 again, and the connection with the short beam 4 is disconnected. The whole process is driven and driven by electric mechanized components, without the need for human participation, achieving the effect of saving time and effort in the process of loading and unloading goods, and has high flexibility, smaller external space occupation, and reduces the number of motors arranged.

[0030] 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.

[0031] Further, the short beams 4 are a pair arranged symmetrically, and the long beams 3 are several pairs arranged symmetrically, and the several pairs of the long beams 3 are arranged layer by layer in the shelf frame, and a plurality of synchronous connecting plates 5 are connected between each pair of the long beams 3, and the synchronous connecting plates can strengthen the relationship between the pair of long beams. A pallet is provided on each layer of the long beams 3, and the pallet can be used to carry goods.

[0032] 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.

[0033] 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.

[0034] Furthermore, the shelf frame also includes a fixed beam 2 connecting the ends of adjacent columns 1 to form a rectangular frame structure.

[0035] Furthermore, the column 1 is a hollow structure, and a vertical guide groove is provided on one side of the column 1 facing the short cross beam 4. A pair of directional racks 10 are provided on the inner wall of the column 1 near both sides of the guide groove, and the transmission gear 9 is meshed and connected between the pair of directional racks 10.

[0036] The directional rack 10 is arranged inside the column 1, so that the internal space of the column 1 can be fully utilized; the arrangement of a pair of directional racks 10 can better connect and support the transmission gear 9, and the bite force is stronger. Preferably, the pitch circle of the transmission gear 9 is 29mm, and the module is 1; the column is a carbon steel profile with a cross-section of about 75mm*75mm, and the profile thickness is about 2.5mm.

[0037] Furthermore, a vertical guide rail 13 is provided inside the column 1 , a slider 12 is provided on the guide rail 13 , and the slider 12 is connected to a second connecting plate 11 , and the second connecting plate 11 passes through the guide groove and is connected to the short cross beam 4 .

[0038] The coordinated arrangement of the second connecting plate 11 , the sliding block 12 and the track 13 can not only play a guiding role, but also improve the connection stability and movement stability of the short crossbeam 4 .

[0039] Furthermore, the magnetic lock includes a first electromagnetic lock 14 connecting the short beam 4 and the long beam 3, and a second electromagnetic lock 15 connecting the long beam 3 and the column 1, the lock body of the first electromagnetic lock 14 is installed in the end of the short beam 4, the lock body of the second electromagnetic lock 15 is installed in the end of the long beam 3, the magnetic attraction plate of the first electromagnetic lock 14 is installed on the end face of the long beam, and the magnetic attraction plate of the second electromagnetic lock 15 is vertically installed on the side wall of the column 1.

[0040] The first electromagnetic lock 14 and the second electromagnetic lock 15 can be independently controlled to complete locking or unlocking operations respectively. The connection structure between the beam and the column can be simplified through the magnetic connection method, and the lock bodies of these electromagnetic locks can be set inside the beam, occupying less external space.

[0041] The first electromagnetic lock 14 and the second electromagnetic lock 15 can both be magnetic locks with magnetic plates or magnetic locks with retractable latches. The latches can be used to further enhance the connection strength, and a lock hole needs to be provided on the cooperating parts to cooperate with them. If the electromagnetic lock and the magnetic lock fail at the same time due to external force, the limit connection between the latch and the lock hole can also serve as the last safety barrier to play a protective role. The magnetic attraction of the first electromagnetic lock and the second electromagnetic lock can be reasonably selected according to the actual load-bearing weight.

[0042] Furthermore, the magnetic plate of the first electromagnetic lock 14 is a short plate, and the magnetic plate of the second electromagnetic lock 15 is a long plate (for example, an electromagnetic lock alignment strip 16, which can be magnetically attracted and has a lock hole), extending from the bottom to the top of the column 1, so that the long beam can be magnetically attracted and docked at any position along the height direction of the column.

[0043] Furthermore, an openable and closable magnetic lock inspection port 17 is provided on the end side of the long crossbeam 3 to facilitate the later maintenance of the internal magnetic lock.

[0044] Furthermore, the driving assembly includes a servo motor 6 and a reducer 7 connected to the servo motor 6 , and the servo motor 6 and the reducer 7 are installed below the short crossbeam 4 through the first connecting plate 8 .

[0045] The coordinated arrangement of the servo motor 6 and the reducer 7 can better control the lifting speed and movement accuracy; preferably, a 400W servo motor with a 1:10 reducer is selected, and the rated speed of the servo motor is 3000R / min.

[0046] 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.
