Intelligent transfer robot for warehouse

Abstract

The invention belongs to the technical field of AGV (Automatic Guided Vehicle), and relates to an intelligent transfer robot for a warehouse. The intelligent transfer robot for the warehouse comprises a trolley located on the bottom part and contacted with the ground. The trolley comprises a bottom plate, bottom frameworks, a motor base plate, universal wheel supporting plate cushion blocks, universal wheel supporting plates and universal wheels, wherein the bottom framework are fixedly arranged on the bottom plate; the motor base plate and the universal wheel supporting plate cushion blocks are fixedly arranged on the bottom framework; the universal wheel supporting plates are fixedly arranged on the supporting plate cushion blocks; the universal wheels are connected with the universal wheel supporting plates; a drive mechanism, a motor, a driver and a storage battery are sequentially arranged on the bottom framework from bottom to top; a rotatable lifting mechanism and a chain compressing mechanism are also arranged on the drive mechanism. The invention provides the intelligent transfer robot for the warehouse, which is reasonable in design, stable in performance, and applicable to the AGV and turns flexibly.

Description

technical field [0001] The invention belongs to the technical field of AGVs, in particular to a warehouse intelligent handling robot. Background technique [0002] AGV has a history of more than 50 years since its invention. With the expansion of application fields, its types and forms have become various. At present, the walking mechanism commonly used by AGV is a four-wheel walking mechanism with steering wheels, which includes two driving wheels and two supporting wheels and is distributed in a diamond shape. The four-wheel walking mechanism with steering wheel is evolved on the basis of the three-wheel walking mechanism. It is equivalent to combining two tricycles together. The fulcrums of the two supporting wheels are at the apex of the isosceles triangle of the base. The front and rear wheels are both steering wheels and driving wheels. This kind of AGV car can track the trajectory of the guide line when the front and rear wheels are turning, and its maneuverability...

AI Technical Summary

Problems solved by technology

However, the walking mechanism also has the following problems: the walking mechanism AGV is not suitable for the in-situ rotation of the AGV in the intensive storage area: when the car body rotates in situ, since the supporting wheels on both sides have no driving force, the flexibility of its rotation is limited. and stability are not enough

Two-way walking AGV car, a single-drive two-way walking AGV is to install a non-rotatable drive unit at the bottom of the body, and install four universal wheels at the bottom of the front and rear ends of the body. When the AGV trolley is walking, the driving wheels drive four universal wheels. When the steering wheels move together, the trolley will travel in a serpentine route during the walking process, and the body cannot be balanced and cannot go straight straight. Compared with a single AGV under the same load, the motor power consumed is larger, and the existing technology The drive unit of this single-drive two-way AGV is fixed relative to the body. When the AGV car turns, the drive unit needs to drive the entire body to turn together, so that the required torque is too large, so that the motor power consumption is too large, and the cost Increase
