[0002] It is well known that the roller-belt translation exchange host of the current intelligent three-dimensional warehouse has a single function and can only realize the device's own cargo translation drive function, that is, each three-dimensional standard warehouse position needs to be equipped with a corresponding motor drive device to cooperate with the roller-belt translation exchange host to realize the cargo storage and retrieval translation drive function. Since each three-dimensional standard warehouse position needs to be equipped with a corresponding independent control component, the electromechanical system of the three-dimensional warehouse position supporting part is complex, the production and manufacturing cost is high, the programming control is complex and the maintenance requirements are high. In addition, the electromechanical parameter errors between the drive motors of each three-dimensional standard warehouse position and the drive motors of the roller-belt translation exchange host will cause the storage and retrieval of the cargo to be translated asynchronously and the positioning accuracy is low. With the rapid increase in the demand for three-dimensional warehouses in China's intelligent manufacturing and smart logistics, it has become a top priority to solve the problems of the single function of the roller-belt translation exchange host and the low translation positioning accuracy of the storage and retrieval of cargo. ; At present, the functions of the roller-belt translation exchange host used in the intelligent three-dimensional warehouse have the following characteristics in its implementation: ① The roller-belt translation exchange host has a single function and can only realize the translation exchange host's own driving function for the translation of goods, resulting in the complexity of the electromechanical system of the three-dimensional warehouse's warehouse matching parts, high production and manufacturing costs, complex programming and control, and high maintenance requirements; ② The electromechanical parameter errors between the drive motors of each three-dimensional standard warehouse and the drive motors of the roller-belt translation exchange host will cause the problem of asynchronous translation and low positioning accuracy of the stored and retrieved goods; With the functions of the roller-belt translation exchange host of the current intelligent three-dimensional warehouse, the problems of complex electromechanical system of the three-dimensional warehouse warehouse matching parts, high production and manufacturing costs, complex programming and control, high maintenance requirements, and low translation and positioning accuracy of stored and retrieved goods due to the single function of the roller-belt translation exchange host have yet to be solved. Summary of the invention

[0003] In order to overcome the problems of complex electromechanical system of the supporting parts of the three-dimensional warehouse position, high production cost, complex programming and control, high maintenance requirements, and low translational positioning accuracy of goods storage and retrieval caused by the single function of the roller-belt translational exchange host used in the existing intelligent three-dimensional warehouse, the purpose of the present invention is to provide a roller-belt translational exchange host with a position power output function that adopts an axial connection structure and a single motor power source synchronous output and an electronically controlled automatic two-way telescopic plug-in sleeve drive mechanism as an organic combination, so as to better solve the problems of complex electromechanical system of the supporting parts of the three-dimensional warehouse position, high production cost, complex programming and control, high maintenance requirements, and low translational positioning accuracy of goods storage and retrieval caused by the single function of the roller-belt translational exchange host in the existing intelligent three-dimensional warehouse.
