[0002] With the rapid development of the logistics industry, its requirements for automation technology are getting higher and higher, especially for improving the handling efficiency of goods and reducing the working intensity of workers. In the prior art, the common ways to solve the problem of handling objects are generally automatic guided vehicles and the like. Although these handling methods have improved the automation level of logistics to a certain extent, improved the conveying efficiency, and reduced the labor intensity of workers, their disadvantages are also obvious. Most of the wheels of the existing load-carrying handling devices are fixedly installed, and their deflection angles cannot be adjusted. Moreover, the front and rear wheels are driven by a single motor, and the wheel speeds cannot be flexibly adjusted to achieve the steering of the device. Content of the Utility Model
