When the supporting drive557rotates, the sector gear553can be driven to rotate, thereby driving the second connecting rod555to move, the sliding rail556can enable the engaging part551to be driven to move in the longitudinal direction so as to achieve engagement. At the same time, in this embodiment, the fixing effect is good and the stability of movement is high, due to connection of four engaging parts551.

Please refer toFIG.1andFIG.2, this embodiment provides a goods shelf system, including a plurality of shelves700arranged in an array, tracks800arranged on the tops of the shelves700and a goods shelf shuttle, vehicle body100of the goods shelf shuttle can travel on the tracks800.

Among them, the goods shelf system can be applied in a warehouse. The warehouse is provided with a plurality of shelves700arranged in a lateral and longitudinal array, aisles are formed between the shelves700; each shelf700is formed with multiple layers of storage spaces, a plurality of goods900may be arranged inside each storage space. The top of the shelf700can be provided with the track800, the vehicle body100of the goods shelf shuttle can move on the tracks800, so as to move in the warehouse, and store and retrieve goods900.

Optionally, the tracks800can include lateral tracks and longitudinal tracks, setting the tracks on the top of the shelf700can make rational use of the space on the top of the shelf700, improving space utilization thereof. The goods shelf shuttle can move in the lateral direction by the first walking device200and move in the longitudinal direction by the second walking device300, thereby docking in the aisle of the shelf700where goods900are located.

When the goods shelf shuttle receives the instruction of taking out goods900in a certain layer of the shelf700, the goods shelf shuttle can lower the access device500by the lifting device600to the layer where the goods900are located, and then transfer the goods900to the fixed part510through the mobile part520, and then move the access device500and the goods900into the accommodating chamber by the lifting device600, and then the goods shelf shuttle can be moved to the designated delivery position for unloading.

In the goods shelf system provided by this embodiment, there is provided a vehicle body, an access device and a lifting device; where an accommodating chamber for accommodating the access device is formed in the vehicle body; the access device includes a fixed part and a mobile part for accessing goods; the mobile part can telescopically move relative to the fixed part; the lifting device is connected between the fixed part and the vehicle body, the lifting device is configured to drive the fixed part to move along a vertical direction, thereby enabling the access device to extend from or retract into the accommodating chamber. Since the access device of the goods shelf shuttle can move in the vertical direction under the driving of the lifting device, the goods in each layer of the shelf can be accessed, thereby reducing the number of the goods shelf shuttle and lowering the production cost.

In the present application, unless otherwise clearly specified and limited, the terms “install”, “couple”, “connect”, “fix” and other terms should be interpreted broadly. For example, it can be a fixed connection or a detachable connection, or integrally formed; it can be direct connection or indirect connection through an intermediary, unless specifically defined otherwise. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific situation.

In the above description, the description with reference to the terms “an embodiment”, “some embodiments”, “example”, “specific example”, or “some examples” etc. means specific features or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features or characteristics described can be combined in any one or more of the embodiments or examples in an appropriate manner. In addition, those skilled in the art can integrate and combine different embodiments or examples and the features of different embodiments or examples described in this specification without contradicting each other.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the present application; although the present application is described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: the technical solutions described in the foregoing embodiments may be modified, or some or all of the technical features therein can be equivalently replaced; these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
