1. Twin Helical Track Parking System, includes two helical tracks, track support devices, and multiple parking racks mounted on the helical tracks. The two helical tracks are installed side by side on the track support devices, and connected by horizontal tracks at both the top and bottom, forming a closed-loop twin helical track system together with the horizontal tracks at both ends. The horizontal track at the bottom also serves as the bicycle entry and exit point. The parking rack includes a parking plate and a bicycle fixation device located on the parking plate. The multiple parking racks are connected end-to-end and are installed on the twin helical tracks through pulley devices, with at least one of the pulley devices equipped with a power drive device. The power drive devices are evenly distributed among the parking racks at certain intervals, driving all the parking racks to circulate on the closed-loop helical tracks. The twin helical track parking system boasts high space utilization, efficient parking and retrieval, as well as being safe and convenient.
