Description

Many topography shuttle with lift layer board

Technical Field

The utility model relates to the related field of logistics storage equipment, in particular to a multi-terrain shuttle vehicle with lifting support plates.

Background

In recent years, warehouses have been increasingly automated due to the increase in the number of stored goods in the industries of e-commerce, logistics, and the like. The automatic stereo warehouse is also called automatic storage system, and is one kind of warehouse with high-rise shelf for storing material, automatic controlled stacker or carrier for storing and taking operation and computerized controlled management. The automatic stereoscopic warehouse has the basic functions of a traditional warehouse, and also has the functions of sorting and tallying, and automatically storing and taking out materials under the condition of not directly carrying out manual processing.

AGVs (automatic guided vehicles) and RGVs (rail guided vehicles) are an integral part of an automated logistics hierarchy. The AGV is mainly used for working on the ground, and an electromagnetic device and an automatic guiding device are arranged on a frame of the AGV, so that the AGV can run on the ground and carry goods according to a set route. RGVs can automatically handle goods without manual manipulation, but are typically used to drive and handle goods on high density storage racks.

In the automatic stereoscopic warehouse in the prior art, in order to store goods on the ground onto a shelf, an AGV is generally required to transport the goods stored on the ground to a storage destination according to a predetermined traveling track, and then store the goods onto corresponding storage locations of the shelf by means of an RGV, and the automatic stereoscopic warehouse has not only the AGV traveling on the ground but also the RGV traveling on the shelf; in a large warehouse, a large amount of transportation equipment is required to meet the storage requirement, and therefore, the cost and the failure rate of the transportation equipment are increased. Therefore, how to reduce the cost of the automated stereoscopic warehouse is an urgent technical problem to be solved.

The dual-mode operation can be realized, the cost is reduced, the structure is compact, higher rigidity and vehicle body strength can be realized, and the processing and the assembly are convenient. However, how to integrate a plurality of wheels, a plurality of transmission systems and power systems into a vehicle body with a relatively small volume does not provide a good solution in the prior art, and particularly does not provide a preferable design scheme and arrangement scheme for integrating the AGV, the RGV and the tray lift transmission operating mechanism into a multifunctional vehicle body.
