[0038] Specifically, in this embodiment, the storage rack 100 is provided with a rack body 110.

The relative distance between the transverse movement guide rail 210 and the rack body 110 is kept constant. The structure of the transverse movement guide rail 210 is adapted to the placement of the rack body 110. For example, if the rack body 110 is a linear structure, the transverse movement guide rail 210 is set as a linear structure; if the rack body 110 is an arc structure, the transverse movement guide rail 210 is correspondingly set as an arc structure. In this embodiment, the horizontal displacement mechanism 200 can be located on one side of the storage rack 100 to set the transverse movement guide rail 210, and the transverse movement of the goods on the single-side transverse movement guide rail 210 is carried out separately.

When in use, the goods or packages are placed on the tray 330 of the load-bearing rack 310. The transverse movement rack 220 slides on the transverse movement guide rail 210 to the specified column, and then the load-bearing rack 310 is lifted to the specified row by the vertical lifting mechanism 300. Finally, the tray 330 is sent into the storage unit 111 through the pushing component 320. Through the design of this structure, the action path is simple, easy to use, the equipment investment cost is reduced, and the transverse movement guide rail 210 can be built following the placement of the storage rack 100. The working range of the horizontal displacement mechanism 200 is large, and the transportation and stacking efficiency of the goods is improved.

[0039] In some embodiments of the present utility model, first roller groups 311 are respectively arranged on both sides of the carrying frame 310. The tray 330 is slidably connected to the first roller groups 311. Two sets of pushing components 320 are provided, and the moving directions of the two sets of pushing components 320 are opposite. Specifically, in this embodiment, the pushing component 320 can control the switching of the tray 330 between the storage unit 111 and the carrying frame 310. The tray 330 serves as the bearing support for goods or packages. When the pushing component 320 controls the tray 330 to enter or leave the storage unit 111, the tray 330 moves on the first roller groups 311, thereby reducing the thrust required by the pushing component 320. In this embodiment, two sets of pushing components 320 are provided, and moreover, the working or moving directions of the two sets of pushing components 320 are opposite. One set of pushing components 320 is used to store external goods in the carrying frame 310 by controlling the movement of the tray 330, and the other set of pushing components 320 is used to store the tray 330 on the carrying frame 310 in the storage unit 111, or take out the tray 330 in the storage unit 111 and place it on the carrying frame 310. Through the design of this structure, not only can the moving range of the tray 330 be increased, improving the working efficiency, but also the structural size of the pushing component 320 can be reduced, thereby reducing the manufacturing cost of the equipment.

Specifically, in this embodiment, the push assembly 320 is provided with two groups, and the moving directions of the two groups of push assemblies 320 are opposite. In this embodiment. The push assembly 320 is driven by a motor screw. Therefore, in this embodiment, the positions of the two sets of push assemblies 320 are close to the two sides of the load-bearing frame 310 respectively. By controlling the initial position of the push assembly 320, the working direction of the push assembly 320 is controlled. When storing goods, the push assembly 320 responsible for receiving the tray 330 into the load-bearing frame 310 starts to work, the lifting cylinder 325 is started, and the driving pin 326 is inserted into the positioning hole 331, so that the tray 330 is fixed on the push plate 322. The screw motor 324 is started to control the push plate 322 to extend outward along the axis direction of the push screw 323. At this time, the tray 330 moves to the outside of the load-bearing frame 310 with the movement of the push plate 322. After the staff puts the goods or packages on the tray 330, the push assembly 320 retracts the initial device and recycles the tray 330 into the load-bearing frame 310. Furthermore, the lifting cylinder 325 controls the pin shaft 326 to be retracted, so that the push assembly 320 responsible for storing the pallet 330 into the supporting frame 310 and the pallet 330 are out of contact.

At this time, the pallet 330 moves into the storage unit 111 with the movement of the push plate 322, and then the pin shaft 326 is retracted, the push plate 322 is out of contact with the pallet 330, and then reset to the initial state, completing the storage of the goods. Through the design of the structure, the work is simple and energy-efficient.

Since in this embodiment, the pushing lead screw 323 is fixed on the pushing base 321, when the pushing plate 322 is driven to move by the operation of the lead screw motor 324, the lead screw motor 324 itself has a tendency to rotate. In order to avoid contact wear between the outer shell of the lead screw motor 324 and the pushing base 321, in this embodiment, the lead screw motor 324 is suspended, and the movement direction of the pushing plate 322 is restricted by providing the auxiliary guide rail 327. Through the design of this structure, the service life of this embodiment can be improved and the failure rate can be reduced.

[0042] In some embodiments of the present utility model, the horizontal displacement mechanism 200 includes a driving rack 240, a horizontal displacement motor 250, and a driving gear 260.

Specifically, in this embodiment, the horizontal displacement mechanism 200 can control the transverse movement frame 220 to move in the horizontal direction. The horizontal displacement mechanism 200 includes a driving rack 240, a horizontal displacement motor 250, and a driving gear 260.

The horizontal displacement motor 250 is arranged on the transverse movement frame 220, and the output end of the horizontal displacement motor 250 is drivingly connected to the driving gear 260, and the driving gear 260 meshes with the driving rack 240. The transverse movement guide rail 210 mainly provides structural support and overall direction control. By arranging the horizontal slide rail 211 on the transverse movement guide rail 210, most of the gravity of the transverse movement frame 220 can be shared by the horizontal slide rail 211, avoiding damage to the gear rack due to excessive load.

In this embodiment, the structure of a ball screw is adopted to control the lifting of the bearing frame 310. The ball screw has high efficiency. The ball screw uses the rolling of balls between the threaded shaft and the female threaded sleeve to reduce friction, thereby improving efficiency. Compared with traditional sliding friction, rolling friction has higher efficiency, which can reach more than 90%.
