[0002] With the change of modern enterprise production and operation modes and the change of external market conditions, the space for reducing product costs by reducing raw material costs and conducting product technology development is getting smaller and smaller. The traditional self-sufficient logistics service cannot compare with professional third-party logistics enterprises in terms of economic benefits, systematization and specialization. This has led more and more enterprises to outsource logistics operations that do not belong to the core competitiveness of the enterprise in order to optimize enterprise resource allocation and enhance market competitiveness, promoting the rapid development of Chinese third-party logistics. The RGV conveyor, that is, the rail-guided vehicle conveyor, is provided with a conveyor chain on its upper part to facilitate the arrival or departure of goods from the RGV cart.

[0003] However, the motor of the traditional RGV conveyor is in the middle of the conveyor chain, which not only occupies space but also limits the minimum size of the goods. Moreover, due to the obstruction of the motor, the height of the conveyor chain cannot be lower than the height of the motor, reducing the stability of the RGV conveyor during movement. Therefore, it is necessary to improve such a structure to overcome the above defects. Summary of the Utility Model
