Description

Technical Field

[0001] This utility model belongs to the field of automated guided vehicles (AGVs), and specifically relates to a multi-layer AGV. Background Technology

[0002] Automated Guided Vehicles (AGVs) are vehicles capable of autonomously navigating predetermined or dynamic paths without direct human intervention. AGVs are widely used in modern warehousing, logistics, manufacturing, and healthcare industries, improving production efficiency and reducing labor costs. In operation, AGVs carry specific transport items on top of them and transport them along predetermined routes. However, most common AGVs are single-layered, limiting the number of items they can transport. Furthermore, some non-compressible items cannot be stacked, resulting in varying transport volumes depending on the nature of the items. This necessitates multiple round trips to complete the intended transport task, potentially impacting actual production and reducing efficiency.

[0003] In summary, the single-layer placement structure of the automated guided vehicle has some problems in use, so we hope to propose a new structure to solve the above-mentioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-layer automatic guided vehicle to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a multi-layer automatic guided trolley, comprising: an automatic guided trolley body, a placement rack, and shelf plates. The automatic guided trolley body is provided with a placement rack for assisting in the placement of items. The placement rack has two sets of symmetrically arranged end rack plates at its upper end. The left and right sides and front and rear ends of the two sets of end rack plates are provided with guide grooves for assisting the linear movement of the shelf plates up and down. Several sets of shelf plates for layered placement of items are installed between the two sets of end rack plates. The front and rear ends of the upper surface of the end rack plates are provided with sealing grooves. The inner side of the sealing grooves is fitted with a different number of sealing plates depending on the number of shelf plates used.

[0006] In a preferred embodiment, a set of mounting seats is fixedly connected to the upper four corners of the main body of the automated guided vehicle. The upper surface of the mounting seats is provided with mounting holes, and the lower surface of the end frame plate is fixedly connected to the main bearing plate.

[0007] In a preferred embodiment, a set of mounting columns are fixedly connected to each of the four corners of the lower surface of the main bearing plate. The mounting columns are interlocked with the mounting holes and fixed with bolts. Several sets of linearly and equally distributed auxiliary grooves are provided on the front and rear sides of the end frame plate. The mounting columns are embedded in the mounting holes and fixed with bolts, which can connect and fix the main body of the automatic guide trolley to the placement frame.

[0008] In a preferred embodiment, a hidden inner hole is provided at the corresponding position of the auxiliary groove on the inner side of the end plate, and a spring is provided inside the hidden inner hole. A push plate is fixedly connected to the end of the spring away from the center of the end plate.

[0009] In a preferred embodiment, a fixed column is fixedly connected to the end of the push plate away from the center of the end frame plate, and the left and right ends of the upper surface of the shelf plate are vertically penetrating to form through grooves. A guide slider is fixedly connected to the inner side of the through groove at the position corresponding to the guide slide groove.

[0010] In a preferred embodiment, fixing holes are provided on the inner sides of both ends of the through slot. The through slot and the end frame plate are interlocked and the guide slider and the guide groove are interlocked. When the shelf plate is in use, the fixing post is engaged with the fixing hole to fix it. According to the required number of shelf plates to be transported, the required number of shelf plates are slid upward and the sealing plate is released from the restriction of the fixing post at the corresponding position, so that the fixing post and the fixing hole are engaged to fix the shelf plate, which can facilitate the transport and use of the goods.

[0011] In a preferred embodiment, the sealing plates are provided in several groups, and each group of sealing plates has a connecting groove on its upper surface. A connecting slider is fixedly connected to the lower surface of the sealing plate. An elastic pull ring is provided above each group of sealing plates. The connecting slider and the connecting groove are interlocked and connected. In a single-layer structure, several groups of sealing plates are embedded in the sealing groove to hide the fixing column in the hidden inner hole. The number of sealing plates is pulled out according to the number of shelf panels used, so that the fixing column is hidden and not exposed when not in use.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By adding an automatic guide trolley, a placement rack, and shelf panels, several sets of shelf panels are placed between the end shelf panels. According to the needs of the transported items, different numbers of shelf panels can be moved to make the guide slider slide in the guide groove. The fixing column is engaged with the fixing hole under the action of the spring force of the fixing spring, so that the shelf panel is fixed to the specified height. Thus, the number of layers can be adjusted to facilitate the transport of items. By adding a placement rack, in the case of a single-layer structure, several sets of sealing plates are embedded in the sealing groove to hide the fixing column in the hidden inner hole. And according to the number of shelf panels used, an equal number of sealing plates are pulled out, so that the fixing column can be hidden and not exposed when not in use.
