Abstract
Description
Technical Field
[0001] The present application relates to the technical field of logistics warehousing robots, and in particular to lifting forks. Background Art
[0002] In high-bay warehouses, pallets are often used as carriers for supporting and storing goods. In order to realize the circulation of cargo pallets in high-bay warehouses, high-bay warehouse robots are often deployed to transport cargo pallets.
[0003] Currently, it is common to deploy horizontal storage robots on the shelves of a high-bay warehouse to transport and retrieve cargo pallets. Furthermore, existing storage robots are typically equipped with bilaterally symmetrical lifting forks on top, which are driven by a lifting mechanism (including a lifting connecting rod) within the storage robot to lift the cargo pallet upward.
[0004] However, due to the lifting characteristics of the three-dimensional storage robot itself (such as: defects or errors in the synchronization system design; some moving or transmission parts wear / deform / loosen after long-term operation, resulting in inaccurate coordination, etc.), the lifting links located on the front and rear sides of the three-dimensional storage robot may be out of sync; in addition, the top of the existing lifting fork adopts a flat structure. During the process of lifting or lowering the cargo pallet, the lifting sequence of the lifting fork in the front and rear directions of the cargo pallet is inconsistent. After multiple operations, it is easy for the position of the cargo pallet to deviate too much relative to the position of the lifting fork, causing the lifting fork to deviate to one side when contacting the contact surface of the cargo pallet, which can easily damage the cargo pallet and even cause problems such as cargo overturning. Utility Model Content
[0005] Based on this, it is necessary to propose a lifting fork that can limit the deviation of the cargo pallet due to the asynchronous front and rear lifting links, thereby reducing damage to the pallet and the possibility of overturning of the cargo thereon.
[0006] This application provides a lifting fork, which adopts the following technical solutions:
[0007] The lifting fork comprises a fork body, wherein the fork body is provided with a limiting member; there are a plurality of limiting members, which are arranged at intervals along the length direction of the fork body.
[0008] Preferably, the limiting member is located at the top of the fork body.
[0009] Preferably, the limiting member is a limiting groove provided on the top of the lifting fork, and the limiting groove is a flared structure.
[0010] Preferably, the limiting member is a positioning block spaced apart from the fork body, the length direction of the positioning block is perpendicular to the length direction of the fork body, and the top of the positioning block is located above the top of the fork body.
[0011] Preferably, there are a plurality of limiting grooves, which are spaced apart along the length direction of the fork body.
[0012] In summary, this application has the following beneficial effects:
[0013] When the fork is lifted to pick up the cargo pallet, the position limiter is used to limit the position deviation of the cargo pallet caused by the asynchronous lifting sequence, thereby avoiding damage to the cargo pallet and reducing the possibility of cargo overturning.

[0019] Reference Figure 1 and Figure 2 The lifting fork disclosed in the embodiment of the present application includes a fork body 1. Two forks 1 are symmetrically mounted on top of a three-dimensional storage robot 2. A lifting mechanism (including a lifting link 21) within the three-dimensional storage robot 2 drives the fork bodies 1 to lift the cargo pallet 5 upward, thereby enabling the circulation of the cargo pallet 5 within the three-dimensional warehouse. It should be noted that the three-dimensional storage robot 2 in the present application is not limited to transporting cargo pallets; the fork bodies 1 can also transport vehicles such as cage trucks.
[0020] Reference Figure 2 and Figure 3Furthermore, the lifting fork is provided with a limiting member for limiting the position of the cargo pallet 5. In other embodiments, the limiting member can also limit the position of a carrier such as a cage truck on the fork body. The limiting member is a limiting groove 3 provided on the top of the lifting fork, and the limiting groove 3 is a flared structure. There are three limiting grooves 3, which are spaced apart along the length direction of the lifting fork; and the opening position, size and shape of the limiting groove 3 are designed according to the "Chuan" structure at the bottom of the cargo pallet 5. In the process of lifting or lowering the cargo pallet 5 by the lifting fork, the limiting groove 3 on the top of the fork body 1 is used to cooperate with the structure at the bottom of the cargo pallet 5 (that is, the limiting groove 3 is plugged into the "Chuan" structure at the bottom of the cargo pallet 5) to limit the position of the cargo pallet 5, which can effectively avoid damage to the cargo pallet 5 and reduce the possibility of overturning of the cargo.
[0021] Reference Figure 3 and Figure 4 In addition, the limiting member can also be a positioning block 4 fixed to the top of the lifting fork. There are four positioning blocks 4 and they are spaced apart along the length direction of the lifting fork. The top of the positioning block 4 is located above the top of the fork body 1, and the length direction of the positioning block 4 is arranged perpendicular to the length direction of the fork body 1. The shape, size and position of the positioning block 4 on the fork body 1 are also designed based on the "chuan" structure at the bottom of the cargo pallet 5. In other embodiments, the limiting member can also take the form of a positioning pin, etc., and the cargo pallet 5 has a corresponding structure to achieve position restriction.
[0022] The implementation principle of the lifting fork in the embodiment of the present application is:
[0023] During the process of lifting the cargo fork to insert the cargo pallet 5, the position of the cargo pallet 5 on the fork body 1 is limited by a limiting member (limiting groove 3 or positioning block 4, etc.), thereby avoiding positional deviation of the cargo pallet 5 due to the asynchronous lifting sequence, thereby avoiding damage to the cargo pallet 5 and effectively reducing the possibility of overturning of the cargo.
[0024] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
