Tooth-shaped rail for single-rail conveyor

The utility model discloses a tooth-shaped rail for a single-rail conveyor. The device comprises guide rails, supporting stand columns and racks. The rack is a linear tooth profile rack of which the tooth top and the tooth bottom are arranged to be arc-tooth-shaped; the arc radius of the inner side of the tooth bottom close to the guide rail end is correspondingly matched with the radius of the driving wheel roller; the tooth pitch of the rack corresponds to the distance between every two adjacent pin rollers of the driving wheel, the ratio of the full tooth height of the rack to the radius ofthe pin rollers of the driving wheel is 2.4-2.5 times, the arc radius of the inner side of the tooth top is smaller than the arc radius of the inner side of the tooth bottom, and the tooth profile angle of the rack is 28-29 degrees. According to the utility model, the tooth profile of the existing tooth-shaped track rack and the corresponding parameters of the full tooth height, the tooth profileangle and the tooth pitch
