The jack-up AGV trolley car, that is, the unmanned truck/automatic guided transport vehicle, belongs to the field of wheeled mobile robots. Under the control of the control system, it can automatically travel along the prescribed guiding path according to the established algorithm to reach the designated place. Completing a series of tasks is one of the main equipments for material transportation automation in the factory, especially for warehousing, manufacturing, medicine and special hazardous areas. The jack-up AGV trolley refers to a jack-up AGV trolley with a jacking mechanism for lifting cargo. The jacking mechanism of the conventional jack-up AGV trolley adopts a screw nut, which is provided with a jacking device and a top. The lifting device comprises a lifting frame and a lifting mechanism for driving the lifting frame, the lifting mechanism comprises two sets of synchronously moving screw nut pairs, and is driven by the double output shaft motor, and the lifting device further comprises preventing the lifting frame from lifting Guided yaw during the process. The jack-up AGV trolley is suitable for lifting lighter weight objects, but there is a shortage of bearing capacity for one ton or more of cargo on the factory or workshop. Of course, multiple loads can be added. Screws, replacement of larger models of motor drives to meet the requirements, at the same time, because multiple screws need to be synchronized and raised, it is necessary to add more transmission mechanisms to ensure the synchronization of multiple screws, or increase the drive of multiple motors With multiple screws, the increase in the number of motors can also lead to a complicated system structure. Therefore, the jacking of heavy cargo causes the structure of the jacking mechanism to be very complicated, and the probability of failure when the mechanical components are excessive is significantly increased.
