Single-power traverse moving system

The invention discloses a single-power traverse moving system which comprises a steel structure rack (1), car carrying boards (2) and a traverse moving motor (3), wherein each car carrying board (2) comprises a board body (4), a travelling wheel (5) and a chain wheel group arranged at one side of the board body (4); each chain wheel group comprises one big chain wheel (6) and two small chain wheels (7), and the two small chain wheels (7) are respectively positioned on two sides of the big chain wheel (6); a chain wheel shaft of each big chain wheel (6) is provided with a chain wheel enclasping mechanism; and the traverse moving motor (3) is connected with the big chain wheels (6) on all the car carrying boards (2) through driving chains (9). The system disclosed by the invention has the beneficial effects that waste of resources and the systems operation cost are reduced, the operation is simple, positioning is accurate, and the system stability is high, when the motor operates, the traverse movement and stillness of the car carrying boards can be switched randomly; and the travelling wheel is provided with a power-off brake, thus the device safety is high.
