RGV lifting shaft and vehicle body positioning pin self-adaptive speed cooperative lifting method

The invention relates to an RGV lifting shaft and vehicle body positioning pin self-adaptive speed cooperative lifting method, and belongs to the technical field of vehicle automation. Two sets of vehicle body positioning mechanisms and one set of rail guided vehicle RGV are combined, a floating plate 1 is arranged on a lifting plate 2, the lifting plate 2 is controlled to ascend and descend through an iron chain 3, a gear 6 is controlled to rotate by a driver 8, a rack 5 is matched with the gear 6, the rack 5 drives a vehicle body positioning pin 7 to ascend and descend, and a sensor 4 is arranged at the limiting position of the rack 5 and used for sensing the position of the vehicle body positioning pin 7; through a software program, the RGV lifting shaft and the vehicle body positioning pin servo are combined for use, and by means of PLC calculation, the major risk caused by the phenomenon that after parameters are set unsatisfactorily, personnel abut against a power battery or a vehicle body can be avoide
