Description

Technical Field

[0001] This application relates to the technical field of automated guided vehicles, and particularly to an automated guided vehicle. Background Art

[0002] An automated guided vehicle, with the full name of "Automated Guided Vehicle" (abbreviated as AGV), is a transport vehicle equipped with electromagnetic, optical, radar laser and other automatic guiding devices. It can travel along a specified guiding path, has safety protection and various transfer functions, and does not require manual operation.

[0003] When the existing automated guided vehicle carrier transports a shelf, it does not limit the shelf. When the automated guided vehicle starts, brakes or turns quickly, the shelf may move or tilt due to inertia, increasing the risk of goods slipping or the entire shelf toppling, causing harm to surrounding personnel and equipment. Since automated guided vehicles usually operate in crowded areas, the overall efficiency of logistics operations is affected.

[0004] Therefore, we propose an automated guided vehicle to solve this problem.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

Chutes are arranged on the sides of the plurality of guide rails close to the carrier. Clamping plates are slidably installed in the chutes. An installation groove is throughly opened between two opposite limiting grooves. A rotating shaft is rotatably installed in the installation groove. A gear is fixedly installed on the rotating shaft. Placing grooves are respectively and throughly opened on both sides of the installation groove and the limiting grooves. Support frames are fixedly installed on the sides of the two sliding plates close to the installation groove. Rack bars are fixedly installed on the sides of the two support frames close to the gear. The two rack bars are meshed with the gear. A driving mechanism is arranged in the chute.

[0009] Preferably, a jacking mechanism is arranged in the middle of the vehicle body, and the jacking mechanism is in transmission connection with the bottom of the carrier.

By providing the guide rails 3 and the clamping plates 4, the shelves can be limited after being lifted, so that the vehicle body 1 remains stable during rapid start, braking or turning, preventing the goods from slipping or the shelves from tipping over, and increasing the overall efficiency of logistics operations.

[0021] Refer to Figure 2 , a jacking mechanism 17 is provided in the middle of the vehicle body 1, the jacking mechanism 17 is in transmission connection with the bottom of the carrier 2 and can drive the carrier 2 to rise, thereby driving the shelf to rise.

[0022] Refer to Figure 2 and Figure 4 , the driving mechanism comprises a screw rod 8 and a first motor 5, the screw rod 8 is rotatably installed in the guide rail 3, the screw rod 8 is in threaded connection with the clamping plate 4, the first motor 5 is fixedly installed on the top of the guide rail 3, and the output end of the first motor 5 is in transmission connection with the screw rod 8, which can drive the clamping plate 4 to move downwards to clamp the shelf.
